Plate type heat exchanger

Abstract

A plate heat exchanger in which the various plates from which it is fabricated are brazed together in a stacked assembly comprised of flow plates and heat transfer plates arranged in alternating relationship. The heat exchanger has inlets and outlets for two fluids with passage networks extending between the inlets and outlets and turbulator members are located in each flow cavity formed between adjacent surfaces of the heat transfer and flow plates. The turbulator members are interchangeably positionable between each pair of adjacent flow and heat transfer plates and are selectable from a plurality of differently configured turbulator members. Plate sizes, shapes and openings therein are standardized to provide a basic heat exchanger system which can be fabricated in easily modified embodiments to meet various and diverse heat exchange requirements.
