换热板片、板式换热器及换热系统
By setting concave or convex curved surfaces or inward or outward inclined flat welding surfaces on the heat exchange plates, the problem of reduced effective heat exchange area caused by increased welding surface size is solved, thereby improving the pressure-bearing capacity and heat exchange performance of the plate heat exchanger.

AI Technical Summary
The welding surface of the existing heat exchange plates extends parallel to the plate plane, resulting in an increased welding area, which sacrifices the effective heat exchange area and affects the pressure-bearing capacity and heat exchange performance.
A first protrusion is provided in the height direction of the heat exchange plate, and the welding surface is a concave or convex curved surface or an inward or outward inclined plane, which increases the contact welding area without changing the projected area of the welding surface in the height direction, forming a contact welding surface that is compatible with the concave curved surface and the convex curved surface or the inward and outward inclined plane.
The welded structure strength was improved, the effective heat exchange area was increased, and the pressure-bearing capacity and heat exchange performance of the plate heat exchanger were enhanced.
