A cooling system in which an electronic component is cooled by using one or more containers of liquid and sorbent that transfer heat from the component to the fluid in the well bore. According to the present invention, a sorption cooling system is provided for use in a well, Such as down hole tool which is in a drill string through which a drilling fluid flows, or in a down hole tool, which is on a wire line. This cooling system comprises a housing adapted to be disposed in a wellbore, the sorption cooler comprising a water supply adjacent to a sensor or electronics to be cooled; a Dewar flask lined with phase change material surrounding the electronics/sensor and liquid supply; a vapor passage for transferring vapor from the water supply; and a sorbent in thermal contact with the housing for receiving and adsorbing the water vapor from the vapor passage and transferring the heat from the sorbed water vapor through the housing to the drilling fluid or well bore. The electronics or sensors adjacent to the water supply are cooled by the evaporation of the liquid.

1. A sorption cooling apparatus for use in cooling a region in a down hole tool housing deployed on a wire line tool or a drill stem comprising:a container of liquid positioned adjacent to at least one of a sensor or electronics package, the container of liquid forming a first region within the down hole tool; a desiccant located in a second region of the tool; a check valve for preventing spillage of the liquid; and a vapor passage between first region containing the liquid and the second region containing the desiccant, thereby enabling vapor generated during evaporation of the liquid to pass from the first region through the vapor passage to the desiccant in the second region, thereby transferring heat from the first region to the second region.
