Abstract
The prevent invention provides a plate heat exchanger. The plate heat exchanger comprises heat exchange plates each forms one or more first fluid channels and one or more second fluid channels. The one or more first fluid channels each has a fluid channel upstream portion and a fluid channel downstream portion separated from the fluid channel upstream portion, wherein the fluid channel upstream portion is fluidly communicated via a fluid communication device with the fluid channel downstream portion. The plate heat exchanger according to the present invention achieves uniform distribution of the refrigerant while being independent of the distributors, and, provides different heat exchange regions in the channels on the basis of heat-transfer mechanism correlated to refrigerant evaporation, to reinforce the heat transfer. The plate heat exchanger, without the distributors, according to the present invention not only reduces difficulties on productions and processes, but also, widens practical application scopes and conditions. In addition, as there is no distributor in the plate heat exchanger, compared with other similar products, the refrigerant stream has a lower total pressure d…
