Abstract: A plate heat exchanger includes a plurality of heat transfer plates; a first fluid channel and a second fluid channel formed between adjacent heat transfer plates and fluidly isolated from each other; an upstream outlet port and a downstream inlet port formed in each of the heat transfer plates; and a fluid communication device. The first fluid channel includes a fluid channel upstream portion and a fluid channel downstream portion that are separated from each other. The upstream outlet port is communicated to the fluid channel upstream portion of the first fluid channel, while the downstream inlet port is communicated to the fluid channel downstream portion of the first fluid channel. The upstream outlet port and downstream inlet port are fluidly communicated with each other through the fluid communication device. By adopting the plate heat exchanger according to the present disclosure, a number of parts may be reduced.
