The heat exchanger with a controlled coefficient of thermal expansion (CTE) includes a low CTE thermal expansion control member operatively connected to a heat transfer member in order to restrain the lateral thermal expansion of the heat transfer member during use. The thermal expansion control member is placed outside the heat transfer path, so the thermal expansion control member can be made of a low thermal conductivity material without increasing the thermal resistance of the heat exchanger. The CTE of the thermal expansion control member is lower than that of the heat transfer member, so as to constrain lateral thermal expansion of the heat transfer member during operation. The difference between the CTE of the device being cooled and the heat transfer member, i.e. the CTE mismatch, is reduced over conventional heat exchangers by restraining the heat transfer member during operation. |
