Heat exchange plate for plate heat exchanger, and plate heat exchanger

Abstract

A heat exchange plate for use in a plate-type heat exchanger, and a plate-type heat exchanger having same. The heat exchange plate having a heat exchange portion and a port portion; fluids having different temperatures exchange heat with each other by means of the heat exchange portion; an opening used as the port of the heat exchanger is formed in the port portion. The heat exchange plate includes a first side and a second side in a direction perprendicular to the heat exchange plate; the port portion is provided with a contact porition that is in contact with the port portion of another heat exchange plate at the first side, and a protrusion protruding towards the second side relative to the contact portion. The heat exchange plate and the plate-type heat exchanger of the embodiments of the present invention can, for example, improve the quality of the port portion of the heat exchange plate of the heat exchanger.
