Abstract

A heat exchange plate includes main protrusions, intermediate protrusions and non-protruded portions. The main protrusions having a truncated cone or pyramid shape are placed in positions based on a pattern on the plate. The intermediate protrusion is placed between two main protrusions that are adjacent to each other at a shortest distance so that the main protrusion is connected to two other main protrusions through two intermediate protrusions. The intermediate protrusion is defined by a flat portion extending to opposing surfaces of the two main protrusions. The intermediate protrusion has a peak portion placed in a lower position than a top of the main protrusion. The non-protruded portion is placed between adjacent intermediate protrusions. The non-protruded portion is placed in a lowest position relative to a protruding direction of the main and intermediate protrusions so as to provide a recess surrounded by the main and intermediate protrusions.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates a heat exchange plate, which is formed of a metallic plate and to be used in combination with the other heat exchange plates having the same structure so that they are combined in parallel and integrally with each other to form a heat exchanger, and especially to such a heat exchange plate that permits to provide an integrally combined state for the heat exchanger in which an appropriate heat exchange can be made between heat exchange fluids in correspondence with differences in characteristic property therebetween, while causing the heat exchange fluids to flow along the opposite surfaces of the heat exchange plate, respectively, thus enhancing heat exchange efficiency.

[0003] 2. Description of the Related Art

[0004] If there is a demand that heat transfer coefficient is increased to enhance heat exchange efficiency, utilizing a heat exchanger by which transfer of heat (i.e., heat exch...
