Hey guys been a long while since I've posted but I ask today to start an opinion based discussion, how viable do you think Coolshirt from Coolshirt.com with a pair of pants, utilizing a liquid cooling system for a PC tower, do you suppose you could find a way to hook it all together to stay cool and keep you cool under your armor? Using the ODST back pack you could hide this unit in there I suppose. Let me know what you guys think. Seans backpack looks like it cool be a pretty good base the build this into. Thoughts and opinions.
 
I saw the coolshirt thing awhile back and honestly I'm a bit skeptical, it isnt made for armor as far as how it fits, but the concept is pretty amazing. Once I grasp how to make a pump that can fit inside the backpiece and or resevoir, I would stitch tubing into my actual undersuit matching the contours of it and making sure it actually covers the arterial areas, and incorporate a valve closing mechanism that can hook up or detach when putting the chest piece over the suit. theres gotta be a cheap macgyver alternative to coolshirt because they are pretty pricey
 
Just before the beginning of next month, I will be testing out an idea I have had in the works for quite a while. I have a couple of unused camelbacks and will be taking out the bladders from them, plumbing in and sealing a input hose, and using the exit hose to create a recirculating cooling system. I have a water pump already for the testing phase, but it is huge and heavy. I have already added the radiator, fan, 12v Li-Po 8600mah battery pack, and tiny 12v water pump to my Amazon wish list pending the results. My idea is to have a bladder on my chest and on my back, both under my Exo-suit, with quick connects to hook up to the pump/fan/radiator which will be built into the center portion of my Rogue's back piece (all together they are less than 5"x5"x1 1/2") or possibly the new jet pack I just built. The only hiccup I can see is if one of the bladders does not pass water through it properly and starts backing up. My main idea is to use as little water as possible (maybe 6-12 oz. total) and vacuum seal the system so that there is absolutely no air in any portion.

Does anyone have any ideas about or experience with this?
 
I'll look around and see what I can find.

A serious challenge associated with body armor, apart from its excessive weight, is the heat caused by lack of effective perspiration, eliminating the body's natural ability to dissipate and dispose of metabolic heat. Increasing heat stress exhausts the human body within a short time, even under normal conditions, let alone the extreme heat encountered in the Middle East and Central Asia.

Personal Cooling Systems

Enabling troops to endure these conditions, cooling vests are worn under the body armor or assault vests, preventing 'heat overload' on extended missions. Unlike 'air conditioners' that cool an entire space, these personal cooling systems sustain a microclimate just around the human body. Microclimate can be sustained by circulating dry, fresh air, liquid, ice or wax to draw and absorb heat from fighter pilot suites.





Yet, applying these systems for use by infantrymen is more challenging due to strict weight and power constraints. Currently available personal cooling systems are based on one of two principles: body ventilation or heat transfer. Body ventilation systems are designed to circulate air between the body armor and the skin surface, using electrically powered fans. Heat transfer systems are absorbing heat directly from the skin by circulating cool gel through the vest. Both of these methods have their drawbacks - whereas electrical fans are dependent on a power source, Phase Change Material (PCM) like ice or paraffin lose their ability to cool after some time, as they exhaust their potential to absorb heat. Both systems add significant weight (about 4 – 5 pounds in average) to the soldier's load. A typical cooling vest is the MCCS.

This colling vest, comprising part of the US Army PEO Soldier microclimate kit, uses a air blower and water, circulated inside the vest to absorb and remove body heat.Current personal cooling systems have serious limitations – they are heavy, and cumbersome to wear under the body armor. Most versions have limited duration (less than two hours) and must be 'recharged' between missions. New systems, currently in development, are aiming to overcome these limitations, by introducing more efficient microclimate cooling by combining electrical ventilation and phase change methods.

Phase Change Materials (PCM's)

PCM's are absorbing body heat by acting as 'heat sink'. The PCM is activated when the temperature rises above a certain level, an activated PCM then absorbs heat as it transitions to a liquid state. After the mission, the PCM is 'recharged' by transforming back to a solid or semi-solid state in refrigerators, freezers, or in ice and water. Cooling vests are worn either over a T-shirt or next to the skin. This heat transfer garment conducts phase change gel like material, to extract the body heat from under the body armor, dissipating the heat outside the armor shell, which normally blocks natural perspiration. Photo: TPIThe material freezes at a temperature of 65 degrees Fahrenheit (F) for optimum cooling. The pack sustains cooling for up to two hours at 100 degrees F. Further enhancement of the PCM concept is applied in the design of cooling underwear, worn under the armor and helmet.

A typical cooling vest, designed by TPI includes a cooling vest circulating cooled water through a specially designed shirt, shorts and a cooling pad for the helmet. These elements are embedded with cooling channels linked to a heat exchanger. The system uses a thermostatically controlled valve to regulate the water flow through the heat exchanger, to establish an optimal operating temperature. The suit uses 'camelback' style backpack bladder to contain up to two liters of frozen water and is designed to sustain several hours of operation without coolant replacement.

Body Ventilation Systems

Another concept is a lightweight 'spacer vest', designed to assist the natural cooling through perspiration, which is blocked by the thermal insulation of the body armor. The US Army tested such a system designed to distance the Interceptor Body Armor (IBA) from the wearer's skin surface,Spacer kit demonstrated on this enhanced body armor, designed for future soldier systems. therefore increasing evaporative cooling around the torso. The tests demonstrated an improvement of up to 20% in the evaporative cooling potential when wearing the spacer vest, compared to wearing standard IBA.

The Israeli company Rabintex developed a lightweight cooling system known as Breeze, utilizing a lightweight battery powered ventilation system that reestablishes the natural cooling by perspiration. By feeding fresh air beneath the body armor, the Breeze vest facilitates cooling by wicking moisture from the body and cooling through the natural phase change process. The vest weighs only 0.4 kg (0.9 pounds) and does not require additional coolant. Breeze is worn under most types of body armor vests, and is powered by standard AA batteries. A similar system developed by Global Secure is known as the Body Ventilation System (BVS). A concept drawing of the elements included in the Breeze vwst. Photo: Rabintex.In 2006 over 2,200 systems were shipped to equip troops in Iraq and Kuwait. BVS was designed to be worn underneath the Interceptor Body Armor (IBA). Weighing less than five pounds, BVS uses rechargeable lithium ion batteries to power a blower for up to eight hours.

Future Improvements

A more advanced cooling system is under development for the Future Force Warrior (FFW) Program and is expected to mature into a working prototype by mid 2008. This system will support the soldier operating the standard FFW suite as well as the full NBC protected gear. The 3.5 lb system will provide microclimate control by circulating cooling water. FFW project team is also considering the use of spaced personal armor to improve resistance to impact, trauma and improve heat transfer through evaporation and permeability. In the UK, another microclimate suite is currently under development for the British Army and is expected to complete development within two years (2009). This system is designed to weigh around four pounds, provide 100 watts of cooling to operating for four hours. Further improving performance, the US Army Natick Soldier RD&E Center is studying different physiological and technological means to extend the operational endurance and efficiency of future personal cooling systems.

Cooling can also be achieved by applying thermal regulation elements into the body armor. Such a concept is described in a patent registered by John Hopkins University's Applied Physics Lab (APL). This concept is eliminating entirely the need for a liquid coolant or phase change materials by using high thermal-conductivity channels embedded into the body armor itself. The heat conductors are applied over a moisture wicking layer pulling moisture from the body and dispersing the moisture to the outer surface where it can evaporate.

Farther into the future, warfighters will be 'tuned' to maintain peak physical and cognitive performance under stressful and harsh battlefield environment, by increasing tolerance to extreme climates (heat and cold). At DARPA, scientists are studying several concepts, including feeding soldiers with special nutrients and supplements optimized for enduring peak physical stresses, and customizing their vitamin consumption based on each individual’s unique metabolism. The program has recently identified a key bio-molecule that is altered by stress, and may be causative for muscle fatigue following rigorous exercise. Scientists are also studying the principles of thermo-regulation, by controlling the core body temperature by bio-electronic means, thus cooling or warming the body by increasing the levels of heat transfer in certain areas, for example, through the palms and soles.
 
This is really great that I found out about this overheating problem associated with cosplay armour, because as a person with high metabolism I overheat, fast.
 
hey cool subject you could try the setup i am working on . get a old mini fridge and take out the fans and thermal coolers out and hook it up
with a picaxe wireless board get the usb board
 
I'm working on a similar project westley72, I'm using a peristaltic pump and peltier cooler with an aluminum heat exchanger I made (similar to a CPU water cooling block). The problem I'm having is similar to what's been expressed above: power. The peltier cooler uses a good amount of power and it's difficult to get a long usage out of it.
 
I'm working on a system like this too. Using a pre tubed cooling vest from Veskimo. The trick is to not have the peltier running all the time, use tie in thermostats and an arduino to control everything. I'm still finishing some other things on my suit, but once they are done, i'll be fitting my whole cooling system in next. :)
 
Has anybody used these for cosplay before? They look and sound like a great idea, but I want to know if it is practical and useful for that price.
 
shadowkitfox you could try 24 volt rechargeable batteries wired in series you will need a voltage regulator and capacitors to take off some of
load off the batteries
