Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0022] like figure 1 and 2 As shown, a high-efficiency combined distributor structure for heat exchangers in refrigeration systems, including sequentially connected cover plate 1, first gasket 2, distribution plate 3, second gasket 4, end cover 5, third Gasket 6, tube sheet 7, end cover 5, and tube sheet 7 are fixedly installed on the shell end face 8 of the heat exchanger through flanges. The tube sheet 7 is processed with a plurality of liquid inlet holes 10, and the liquid inlet holes 10 are connected with the heat exchange The heat exchange tubes 11 in the device are correspondingly communicated. Three end cap screws 12 and six cover plate screws 13 extend vertically outward from the outer end surface of the tube plate 7 , and the ends of each screw are screwed into the tube plate 7 through external threads or welded to the tube plate ...

Abstract

The invention relates to a refrigerating system, and provides an efficient combined distributor structure for a refrigerating system heat exchanger. According to the invention, distribution channels are machined in a cover plate, a distribution plate and an end cover respectively, single-hole or double-hole inlet liquid is evenly distributed to multiple holes through three-stage distribution channels, the liquid is output and enters multiple heat exchange tubes, evenness of refrigerants in the heat exchange tubes is guaranteed, and the heat exchange effect is improved; and the cover plate, the distribution plate and the end cover are fixed and corresponding sealing gaskets are fastened in a layered fastening mode of three groups of bolts, so that leakage at the sealing gaskets can be effectively prevented, firm sealing is ensured, and meanwhile, the problems of inconvenience in disassembly and assembly, liquid leakage and the like caused by welding are effectively avoided.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a high-efficiency combined distributor structure for a heat exchanger of the refrigeration system. Background technique [0002] Since the shell-and-tube heat exchanger in the refrigeration system does not use a refrigerant distributor, there is a problem of uneven liquid separation, which leads to the inability to fully utilize the heat transfer area and poor heat transfer efficiency; in order to meet the requirements of uniform liquid separation, usually in The distributor is installed at the liquid inlet of the heat exchanger, and the distributor is directly connected to the heat exchange tube by welding. This connection method has the problem of inconvenient disassembly and assembly of the distributor. At the same time, there are solder joints on the fluid side of the heat exchange tube. The material state of the heat exchange tube has been changed, and there are defects such as hidd...
