Mechanical assembly for regulating the temperature of an electronic device which incorporates a heat exchanger that contacts an entire planar face on the device except for its corners

摘要

A mechanical assembly for regulating the temperature of a chip is comprised of a heat exchanger which has a face for mating with a planar surface on the chip. A frame is coupled to the heat exchanger such that the face of the heat exchanger is exposed and can contact the planar surface of the chip. And, the face of the heat exchanger has a shape which makes contact with the entire planar surface on the chip except for each of its corners. One particular embodiment of the heat exchanger has four grooves which extend from the face and which respectively align with the corners of the chip. Due to those grooves, initial contact between the face on the heat exchanger and the planar surface on the chip occurs on an edge of the chip which is spaced-apart from a corner. Consequently, the chance of breaking the tip of a corner off of the chip is reduced.
