specific Embodiment 1

[0041] see Figure 1-12 As shown, a special plate evaporator of a refrigeration evaporation system according to the present invention includes an evaporator body 1, and the evaporator body 1 includes 100 layers of plates arranged at equal intervals vertically between the upper fixing plate 101 and the lower fixing plate 102. 103, the outer part between the adjacent upper and lower plates 103 is surrounded to form a "Y" shaped fin 104, so that a cavity structure is formed between the adjacent upper and lower plates 103, and a set of refrigerant exchange circulation channels are opened in the evaporator main body 1 and a set of heat medium exchange circulation channels;

[0042] Each group of refrigerant exchange circulation passages includes two through passages 105 vertically opened in the evaporator main body 1, marked as a and b in the drawings, and the upper end of the passage 105 of the refrigerant exchange circulation passage is provided with two shunt pipes 2, The lower...

specific Embodiment 2

[0054] The difference of this specific embodiment with respect to specific embodiment 1 is:

[0055] Each group of refrigerant exchange circulation channels includes two through channels 105 vertically opened in the evaporator main body 1. The lower end of the through channel 105 of the refrigerant exchange circulation channel is provided with two shunt pipes 2, and the upper end is provided with a refrigerant liquid inlet / refrigerant Liquid outlet 3;

[0056] Each group of heat medium exchange circulation channels includes two through channels 105 vertically opened in the evaporator main body 1.

Abstract

The invention discloses a plate-type evaporator special for a refrigeration evaporation system and a working method thereof, and relates to the technical field of evaporators. At least one group of refrigerant exchange circulation channels and one group of heating medium exchange circulation channels are formed in an evaporator main body; each group of refrigerant exchange circulation channels and heating medium exchange circulation channels comprises two through channels vertically formed in the evaporator main body, wherein the upper end or the lower end of each through channel of the refrigerant exchange circulation channel is provided with a flow dividing pipe or a refrigerant liquid inlet / refrigerant liquid outlet, closed rings in the refrigerant exchange circulation channel and the heat medium exchange circulation channel are arranged in a staggered mode, and flow distribution pipes at the ends of the two penetrating channels of the refrigerant exchange circulation channel or the heat medium exchange circulation channel achieve circulation interaction through flow guide holes in the plate heat exchanger. The heat exchange speed is higher, and the heat exchange effect can be greatly improved; The horizontal arrangement is adopted, so that smooth oil return of the evaporation system is ensured, the occupied area is saved, materials are saved, and the initial investment is reduced.

Description

technical field [0001] The invention belongs to the technical field of evaporators, and in particular relates to a special plate evaporator of a refrigeration evaporation system and a working method of the special plate evaporator of the refrigeration evaporation system. Background technique [0002] A plate heat exchanger is a partitioned wall heat exchanger, a device used to exchange heat between hot and cold fluids. The plate heat exchanger has the characteristics of free combination of different structural types of plates. As a high-efficiency and compact heat exchanger, the heat exchange effect of the plate heat exchanger in the industrial field is much higher than that of the shell-and-tube heat exchanger. With the continuous development of refrigeration technology, the existing vertical plate heat exchanger has the disadvantages of uneven liquid separation, unreasonable structure, and inability to discharge the refrigerant oil, resulting in low heat transfer efficienc...
