ABSTRACT:
A cooling suit system comprises a suit which is adapted to be worn by a person and which has a cooling media flow conduit therein for circulating a cooling media therethrough. A heat exchanger is associated with the suit and is advantageously adapted to be carried on the back of the wearer and it includes an inlet to the heat exchanger which is connected from the flow conduit into an insert of elastic material arranged within the housing of the heat exchanger. An outlet connects the lower end of the insert to the cooling media flow conduit downstream of the inlet. The insert is filled with a cooling media in the form of meltable solid pieces of ice and it is elastically constructed so that it tightly engages around the ice and may compress with the ice in its liquid form from the thawing of the ice. The construction advantageously includes a pressurizable space in the heat exchanger housing surrounding the insert having an excess pressure valve for regulating the pressure of air which is blown into the space by an air supply pump. The pressure is selected so that the insert will be aided in tightly engaging around the ice during the thawing process. The liquid which is cooled by the ice is circulated by a pump through the outlet connection to the cooling media flow conduit of the suit.
