Benefits of technology

[0010]The undersuit includes both a heat conducting envelope, surrounding an outer surface of the conduit, and a heat conducting cloth layer, situated closest to the skin, to aid in a transfer of heat from the wearer's body to the fluid flowing in the conduit. The undersuit pref

Problems solved by technology

It is difficult to use the human body's evaporative cooling system when a person is wearing multiple layers of clothing.
If the water pump efficiency is 50 percent, it means that about 1 W of power is lost.
Furthermore, existing cooling systems are formed of a large number of capillary tubes, which collect heat from a large body area.
This results in large power losses due to the viscose friction in small tubes and very complex and expensive tube connections.
In addition to the logistical problems of this approach, the heat of fusion of water is 6.013

Embodiment Construction

[0018]The present disclosure is directed to a body suit cooling system. Specifically, it is directed to a self-contained system worn by a person to maintain body temperature at healthy levels.

[0019]For purposes of this disclosure, the terms “body armor” and “suit” (hereinafter collectively referred to as “suit” or “protective suit”) refer to any protective clothing worn by a person. The present disclosure is particularly useful when used in conjunction with military suits and other armor worn by soldiers in combat; however, its use is not strictly limited to garments worn by servicemen. The term “suit” can similarly refer to explosive ordinance disposal (EOD) suits. The term “suit” can further include environmental suits designed for particular hostile environments. These suits can include any material which protects the wearer from certain temperatures, climates, or pressures. The term “suit” can also refer to a contamination or a hazardous material (“hazmat”) suit, which protects ...

Abstract

A body cooling system is provided for utilization with a protective suit worn by a person. The cooling system includes an external air flow source that produces an air flow and blows it in free atmosphere towards an evaporative cooling apparatus. A fluid volume flows from the cooling apparatus to a conduit contained in an undersuit worn under the protective overcoat. A pump circulates fluid through the conduit. The undersuit includes both an envelope, surrounding an outer surface of the conduit, and a cloth layer, situated closest to the skin, to aid in a transfer of heat from a body to the fluid flowing in the conduit. The evaporative cooling apparatus can include a radiator body having finger-like projections extending therefrom. A fluid channel is formed within the evaporative cooling apparatus for egress of the heated fluid carried away from the undersuit.

Description

BACKGROUND OF THE DISCLOSURE[0001]The present invention relates generally to a body suit cooling system. More specifically, it relates to a body suit cooling system having an evaporative cooling system that utilizes a free air approach to remove body heat from a person.[0002]A coolant fluid such as water has an advantage of high volume heat capacity and much higher thermal conductivity compared to air. The heat exchange coefficient for liquid such as water is orders of magnitude higher than for air, resulting in the possibility for compact and energy efficient cooling systems. It is difficult to use the human body's evaporative cooling system when a person is wearing multiple layers of clothing. Thus, the evaporative process should occur outside of the person's body suit and water should be supplied from an outside source. Since it takes only about ten milliwatts of power to provide an air flow in an open space, a free air evaporative system can have improved efficiency.[0003]An exa...
