A counterflow heat exchanger has a pair of disklike end plates between which there are disposed a multiplicity of disklike heat transfer walls. The heat transfer walls have peripheral flanges which are fluid-tightly joined to each other to provide spaces between the walls. There are a first and a second pair of spaced openings defined through each heat transfer wall for the passage of a first and a second fluid respectively therethrough. Each heat transfer wall is additionally fluid-tightly joined to an adjacent heat transfer wall on one side thereof at their edges bounding the first pairs of openings, and to another adjacent heat transfer wall on another side thereof at their edges bounding the second pairs of openings, so that two sets of flow paths for the two fluids are formed alternately by and between the heat transfer walls. The two pairs of openings in each heat transfer wall are situated adjacent the peripheral flange thereof for uniform fluid distribution throughout each flow path. There is also disclosed herein a refrigeration system employing the heat exchanger of the foregoing construction as a refrigerant vaporizer.

[ What is claimed is:] [1.] A heat exchanger for use with two fluids of different temperatures, comprising:(a) a plurality of heat transfer walls of substantially disklike shape peripherally fluid-tightly joined in stacked and spaced relationship to each other;(b) there being a first pair of spaced openings defined through each heat transfer wall for the passage of a first fluid therethrough, the first pairs of openings in all the heat transfer walls being aligned;(c) there being a second pair of spaced openings defined through each heat transfer wall for the passage of a second fluid therethrough, the second pairs of openings in all the heat transfer walls being aligned;(d) each heat transfer wall being additionally fluid-tightly joined to an adjacent heat transfer wall on one side thereof at their edges bounding the first pairs of openings, and to another adjacent heat transfer wall on another side thereof at their edges bounding the second pairs of openings, whereby two sets of flow paths for the two fluids are formed alternately by and between the heat transfer walls; and(e) means for the inflow and outflow of the first fluid into and from the first pairs of openings through one set of flow paths between the heat transfer walls, and for the inflow and outflow of the second fluid into and from the second pairs of openings through the other set of flow paths between the heat transfer walls;(f) each heat transfer wall having an annular flange extending along a periphery thereof, the flanges of neighboring heat transfer walls being directly joined to each other so as to provide the flow paths between the heat transfer walls;(g) the first and the second pairs of openings in each heat transfer wall being situated adjacent the peripheral flange of that heat transfer wall, with the flanges serving to uniformly distribute the fluids throughout the flow paths between the heat transfer walls.
