Patent ID: 7272946

Claim:
A cooling suit to be worn on a wearer, comprising: a cloth part; at least one air inlet provided at said cloth part and configured to introduce outside air into the interior of said cloth part; at least one air outlet provided at said cloth part and configured to extract the air within the interior of said cloth part to the exterior; at least one air-blowing means for discharging the air in a space between said cloth part and the wearer's body or an undergarment to the exterior, thereby forcibly causing air-streams within said space; at least one clearance holding means, provided to cover that surface of the at least one air-blowing means which opposes to the wearer's body or to the undergarment, and configured to hold a predetermined clearance between the at least one air-blowing means and the wearer's body or the undergarment; electric-power source means for supplying electric power to the at least one air-blowing means; and air-leakage preventing means for preventing the air-streams flowing between said cloth part and the wearer's body or the undergarment, from leaking to the exterior from a lower end of said cloth part; wherein the at least one air-blowing means introduces the outside air into the interior of said cloth part through the at least one air inlet to cause the introduced air to flow within said space and substantially parallel to a wearer's body surface, thereby increasing a temperature gradient near the wearer's body surface to thereby cool the wearer's body, and thereby contacting the air-streams flowing within said space with perspiration from the wearer's body so as to vaporize the perspiration from the wearer's body to thereby cool the wearer's body by utilizing an effect to take away evaporation heat from the surroundings upon evaporation of the perspiration.
