Abstract:
A system for dissipating heat from an electronic data processor disposed in a casing of an electronic device, comprising:an electronic data processor; a heat transfer unit attached to the processor and having an inner chamber therein including a fluid inlet and a fluid outlet to allow fluid flow therethrough for transferring heat from the processor to the fluid; a heat exchange unit including a heat dissipator in fluid communication with the outlet of the heat transfer unit and configured to receive heated fluid from the heat transfer unit and cool the heated fluid for return to the heat transfer unit; a fluid reservoir in fluid communication with the heat dissipator for temporarily storing cooled fluid; a pump including a shaft-driven impeller disposed within the reservoir for circulating fluid through the system; and an air flow device for directing air from within the electronic device over the heat dissipator and out of the casing.
