Abstract
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.
