    摘要： 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 drop, which brings more spaces for type selection of the expansion valve.

    摘要： A heat exchanger system is disclosed by embodiments of the present invention. The heat exchanger system comprises an upper manifold, a middle manifold and a lower manifold arranged successively from top to bottom, wherein a first heat-exchanging tube is arranged between the upper manifold and the middle manifold, and a second heat-exchanging tube is arranged between the middle manifold and the lower manifold. The middle manifold has a first chamber and a second chamber separated from each other. During circulation of refrigerant, the refrigerant in the upper manifold flows through the first heat-exchanging tube down to the first chamber, and flows via a first communicating part into the chamber of the lower manifold, and subsequently the refrigerant flows through the second heat-exchanging tube up into the second chamber and then returns via a second communicating part to the upper manifold.

    摘要： Disclosed are a fin (1) for a heat exchanger, and a heat exchanger having the fin (1). The fin (1) comprises a fin body (10) in a waveform structure formed by boards, wherein the fin body (10) has two first side surfaces (11) which are opposite one another in a first direction, two second side surfaces (12) which are opposite one another in a second direction, and wave crests and wave troughs, which are on the second side surfaces (12); and the first direction and the second direction intersect. The fin body (10) comprises: a first concave portion (13), wherein the first concave portion (13) is formed in the fin body (10), and is located on the two first side surfaces (11) of the fin body (10). The fin (1) and the heat exchanger are manufactured more simply. Since the connection portions between the wave crests and wave troughs of the fin (1) are approximately perpendicular to a heat exchange tube (2), the condensed water is more easily discharged.
