Abstract
Electronic equipment and the like, particularly electronic equipment used in oil well logging, is kept cool by placing it in a container inside a vacuum dewar filled with a vaporizable fluid such as water. As the water evaporates, it removes heat from the dewar. The water vapor is absorbed inside a canister filled with a water-absorbing material. A thermostatically-controlled valve is provided to limit water vaporization when not required for cooling, thus greatly extending the life of a single charge of cooling fluid.
