Embodiment Construction

[0018] Such as figure 1 and figure 2 As shown, in the heat exchange plate of the present invention, the refrigerant inlet port 1 is elliptical, and a diameter concentric with the port is provided at the edge of the port 1 and is not larger than the major diameter of the elliptical port. The arc-shaped concave portion 2; the arc-shaped concave portion 2 transitions to the first sealing area 4 around the refrigerant inlet orifice through the inclined annulus 3; the edge of the orifice 1 does not exceed the boundary 5 of the first sealing area 4. When the above two heat exchange plates are pressed together, the arc-shaped concave portion 2 is close together, and the orifice 1 forms a waist-shaped notch 6 on both sides of the arc-shaped concave portion 2 . When multiple sets of heat exchange plates are assembled together, these waist-shaped notches 6 form distribution channel openings 7 arranged along the refrigerant inlet channel.

Abstract

The invention relates to a heat exchanging plate for the evaporator of the cooling system and the plate type heat exchanger made of these heat exchanging plates. It comprises inlet elliptic hole of the coolant with arc concave at the edge of the hole. The said arc concave transits to the No.1 sealing area around the inlet hole of the coolant through slanting ring phase, with the edge of the hole not surpassing the No.1 sealing area. While attaching the said two heat exchanging plates, the arc concave along the edge of the coolant inlet, with at least one side with opening of the elliptic hole on the arc concave. When multi groups of heat exchanging plates assembled together, the kidney shape openings forming distributing channel holes arranged along the coolant inlet channel. This invention is simple in processing and assembly. Heat exchanger of this type can realize the even distribution of coolants in all evaporating channels, ensuring the stable evaporating efficiency and use of the equipment.

Description

technical field [0001] The invention relates to a heat exchange plate, in particular to a heat exchange plate used in an evaporator of a refrigeration system. [0002] The invention also relates to a plate heat exchanger, in particular to a plate heat exchanger used as an evaporator in a refrigeration system. Background technique [0003] Plate heat exchangers are often used as evaporators for circulating refrigerants in refrigeration systems. During the use of this plate heat exchanger used as an evaporator, it often encounters the problem that the refrigerant cannot be evenly distributed to the evaporation channels between the heat exchange plates after entering the heat exchanger into the inlet channel, which leads to Some parts of the heat exchanger cannot be effectively utilized, and at the same time, some parts of the heat exchanger will be deformed due to uneven distribution of refrigerant. For example, when the plate heat exchanger is composed of more heat exchange...
