ABSTRACT:
An end plate for heat exchangers, includes a plurality of bodies and a connecting part. Each of the plurality of bodies has a plurality of holes to allow a refrigerant pipe to pass through the plurality of bodies. The connecting part connects the plurality of bodies to each other, with a recess being provided on the connecting part to allow the connecting part to be easily bent. A manufacturing method includes preparing a plurality of fins arranged to provide two or more parallel rows of fin arrays, preparing an end plate provided on a side of the fin arrays to connect the fin arrays to each other, inserting a refrigerant pipe into the fin arrays and the end plate to provide an assembly including the refrigerant pipe, the fin arrays, and the end plate, and bending the assembly at a predetermined angle around the connecting part of the end plate.
