Abstract: 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.

Abstract: A microchannel heat exchanger (800) is manufactured by bonding a first sheet (802a) of material and a second sheet (802b) of material in a first connection pattern for integral formation of a core portion (801) and a manifold portion (808) for the first and second sheets (802a, 802b) of material. A third sheet (802c) of material is then superposed on to the second sheet (802b) of material and bonded in a second connection pattern to the second sheet of material for integral formation of the core portion (801) and the manifold portion (808) for the second and third sheets (802b, 802c) of material.

The core portion (801) and the manifold portion (808) of the heat exchanger (800) are thus integrally created. The interstices between the first, second, and third sheets (802a, 802b, 802c) of material are then expanded to create fluid flow channels (806).

Abstract: Provided are a gasket, a reactor using the same for sealing a spiral, and a manufacturing method thereof. Spirials are continuously installed in the longitudinal direction between an inner pipe and an outer pipe coaxially arranged to form a flow path for a heat medium, so the seal between the spiral and the outer pipe is stably maintained and fabrication of the reactor is facilitated. The gasket is inserted in and coupled with the spiral, and thus does not need additional processing for combining the gasket. The gasket and spiral are coupled by lodging the spiral into a channel of the gasket. Furthermore, since the gasket is evenly coupled in the outer circumference of the spiral, in which a cushion plate made of resilient material is installed, breakage of the gasket during assembly of the outer pipe is effectively prevented and the post-assembly seal between the spiral and the outer pipe is stabilized.
