Externet Posted August 25, 2008 Share Posted August 25, 2008 Hi. I use canned chemicals to 'freeze' electronics as one tool for troubleshooting; and would like to know if there is any canned product that works by heating instead of using a heat gun. Has to be electrically non-conductive, capable of reaching about 80 Celsius. Link to comment Share on other sites More sharing options...
hermanntrude Posted August 25, 2008 Share Posted August 25, 2008 the reason that the canned chemicals cause freezing is that the liquid inside the can is usually a gas at room temperature. As soon as the liquid comes out (and lands on your electronics) it starts to evaporate, very very fast. Evaporation requires energy, and that energy comes from the liquid's surroundings (to some extent, this is your electronics), which cools the surroundings down. In other words it's the process of evaporation which is endothermic, not the fluid itself. I'm not sure I can think of a method by which you could do the opposite conveniently...
