·
OSTI ID:6876127
A heat exchanger apparatus is described comprising: a heat exchanger constituted by a multiplicity of heat exchanger units laminated one upon another; a filter having first and second filter elements for removing any unnecessary substance mixed into a working fluid; holding means, including an end plate, for holding the filter therein; a fixing member having a cylindrical end portion to which the end plate faces and disposed such as to extend through the heat exchanger so that the heat exchanger and the filter are integrally secured to each other; a communicating passage provided within the heat exchanger such as to communicate with the upstream side of the first and second filter elements; a main flow passage provided within the heat exchanger such as to communicate with the downstream side of the first filter element; a subsidiary flow passage provided within the heat exchanger such as to communicate with the downstream side of the second filter element; single seal means for separating the main flow passage and subsidiary flow passage, the seal means being contacting at the end portion of the fixing member so that the seal means travels only a short distance on an outer surface of the end portion of the fixing member when the filter is fixed with the fixing member; and embracing means provided in the end plate, including three wall means, for embracing all surfaces of the seal means except one surface on which the end portion of the fixing member abuts.
