ABSTRACT:
Cooling apparatus is disclosed which comprises a reservoir for compressed, preferably liquified, gas, the reservoir being connected to tubing 130 arranged to be disposed in an article of clothing adjacent to the skin of a user. A solenoid 230 is provided for opening a valve 240 between the reservoir 100 and the tubing 130 to allow pressurized gas to evaporate and escape from the reservoir along tube 130. As the gas evaporates it cools due to latent heat of evaporation thus providing a cooling effect to the user due to heat transfer through the walls of tubing. A control device 200 is provided for regulating the output of cooling gas in dependence on temperature.
