Body cooling apparatus for removing body or external heat in an environment where sufficient cooling by perspiration is not available. The apparatus includes a compressor and a condenser which feeds liquid coolant to a flexible tube network which is held adjacent the body to be cooled. The cooling takes place by the boiling of the liquid within the flexible tube network. The flow of liquid into the network is controlled depending upon the amount of cooling needed.
