Heat exchange plate

Abstract

The invention relates to a heat exchange plate. The heat exchange plate comprises semicircular grooves and projections and bent opposing edges, and further comprises unequal-width grooves, wherein the semicircular grooves and projections which are die-pressed are not interconnected and mutually perpendicular, and the S-like unequal-width grooves are symmetrically added to the non-groove and non-projection area. The S-like unequal-width grooves are symmetrically distributed on two sides (or at two ends) of the grooves and projections, so that the area of the non-groove area of the heat exchange plate is small. Production results show that the thickness of a cooling core made of the heat exchange plate with the semicircular grooves and grooves and the symmetrical S-like unequal-width grooves is two thirds of the original thickness, the strength and rigidity of a passage are better than those of cooling cores of original plate thickness and same specification; and the symmetrical S-like unequal-width grooves are added, so that heat exchange power of the cooling cores of the same specification is increased by 10%.

Description

technical field [0001] The invention belongs to the field of cooling equipment, and in particular relates to a heat exchange plate. Background technique [0002] The company's original plate cooler product for wind turbine nacelle (ZL2009100986880), its core body is composed of thin-plate heat exchange plates, and the heat exchange plates are molded into concave and convex grooves that are perpendicular to each other and do not intersect. One group of opposite sides of the heat exchange plate is made into a male button and then bent so that the male button is on the same plane as the bottom of the convex groove on the same surface. The other group of opposite sides of the heat exchange plate is made into a female button in the opposite direction and then bent. Make the mating opening of the female button and the male button be on the same plane as the bottom of the convex groove on the same plane; several groups of crimped heat exchange plates are used to make the core of th...

AI Technical Summary

Problems solved by technology

Grooves and convex grooves increase the strength of the heat exchange plate, but the heat exchange plate has a large area without grooves, so the overall strength and rigidity of the heat exchange plate are not enough, and the core body composed of thinner heat exchange plates The flow channel is easy to deform, and the thickness must be increased to meet the requirements of the cooler core for the strength and rigidity of the heat exchange plate
