Abstract
Abstract An article provides sealing of an electronic component connected to a mating fluid heat exchanger by providing a diaphragm with an opening shaped to fit about the heat exchanger, the opening forming a sealing lip. A clamping ring, which expands and contracts as a function of temperature is placed around the lip of the diaphragm and subject to a temperature to shrink the clamping ring against the lip and heat exchanger for sealing the diaphragm thereto. Preferably the clamping ring is a shape memory alloy metal. In addition, a compressible metal seal may be placed between the lip and the heat exchanger to increase the ability to seal.
