| 1. A sorption heating apparatus for use in a downhole tool comprising:
a solid source of liquid associated with a first region within the tool;
sodium polyacrylate located in a second region of the tool; and
a passage between the first region and the second region configured to enable liquid vapor released from the solid source
of liquid to pass from the first region to the second region and the sodium polyacrylate configured to soak up the liquid
vapor thus removing heat from first region.
