Abstract

A plate heat exchanger includes a plurality of spaced plates secured together to form a stack having a plurality of fluid flow channels and a first plurality of passages. The channels are divided into at least first and second groups, the channels in the first group spaced from one another by the channels in second group. Each passage in the first plurality of passages extends between adjacent plates through one of the channels in the second group of channels. Each successive passage in the first plurality of passages is in fluid communication with successive channels in the first group of channels, and is offset from each preceding passage in the first plurality of passages such that fluid flowing through the first group of channels and the first plurality of passages follows a serpentine pattern through the stack.
