HEAT EXCHANGE PLATE USED FOR PLATE-TYPE HEAT EXCHANGER AND PLATE-TYPE HEAT EXCHANGER PROVIDED WITH THE HEAT EXCHANGE PLATE

摘要

A heat exchange plate used for a plate-type heat exchanger. The heat exchange plate comprises: a heat exchange part (10); multiples protrusions (14) that protrude from a plate plane (12) to at least one side of the plate plane (12) in the heat exchange part (10), the multiple protrusions (14) being aligned along multiple lines; and a transition part (16) that is between adjacent protrudes (14) aligned along a line and that protrudes to at least one side of the plate plane (12), the size of the top of each protrusion (14) in a direction perpendicular to the line being larger than the size of the top of the transition part (16). Strength of the heat exchange plate of the plate-type heat exchanger is improved by increasing the size of a welding part or a bearing part.

1. A heat exchange plate for a plate-type heat exchanger, the heat exchange plate comprising:
a heat exchange part; multiple protrusions which project at the heat exchange part from a plate plane to at least one side of the plate plane, the multiple protrusions being arranged along multiple lines; and transitional parts which are located between adjacent protrusions arranged along one of the lines and project to the at least one side of the plate plane; in a direction perpendicular to the line, the size of the top of each protrusion is greater than the size of the top of the transitional part.
