Abstract
A heat exchanger plate which has a plate body formed from at least two plate elements and at least one connecting piece for a cooling fluid. The plate body and connecting piece are joined together using soldering. The connecting piece has a joining portion which is joined in a receiving portion of the plate body formed between the plate elements. A solder resist limits the flow of solder when producing the solder connection. The solder resist is able to be formed by a sealing metal, which is arranged on the joining portion of the connecting piece in front of and/behind a solder material applied to the joining portion. The solder resist is able to be formed by an annular bead resting on the end face of the receiving portion.
