[0002] For brazed plate heat exchangers, they are composed of an upper end plate, a lower end plate and several stacked heat exchange plates. Corner holes are set at the four corners of the upper end plate, the lower end plate and the plates. The four corner holes of the heat exchanger form inlet and outlet channels for hot and cold liquids, which are dispersed into the heat exchange channels formed between the plates.
