SELF CIRCULATING HEAT EXCHANGER

摘要

A self-circulating heat exchanger apparatus for dissipating heat from an electronic assembly. An enclosure defines a closed-loop circulation path for coolant. An electronic assembly capable of generating heat is installed into a vertical portion of the enclosure such that heat from the electronic assembly causes coolant in the vertical portion to rise, thereby inducing self-circulation of the coolant in the enclosure. The electronic assembly is coated with a combination of silicon nitride and PARYLENE® in order to protect electronic components from water based coolants such as a mixture of ethylene glycol and water.
