Embodiment Construction
[0009] The present invention will be further explained below in conjunction with the accompanying drawings.
[0010] An external pressure heat exchange tube distributor, characterized in that it includes a shell, a water inlet cavity, an exchanger, and a light pipe, and a gas-liquid heat exchanger is arranged above the outer shell; Inlet distributor; the side of the water inlet chamber is equipped with a water separator; the thin-walled bare pipe body or the thin-walled external pressure heat exchange pipe body is characterized in that the bare pipe body or the external pressure heat exchange pipe The end wall thickness of the body is greater than the body wall thickness.
[0011] By adopting the above solution, the present invention has a simple structure, maintains the heat exchange efficiency of the thin-walled heat exchange tube, and simultaneously solves the problem of welding between the heat exchange tube and the tube sheet.
[0012] The above content is only a preferr...

The invention discloses an externally-pressed type heat exchange pipe distributor. The externally-pressed type heat exchange pipe distributor is characterized by comprising a shell, a water feeding cavity, an exchanger and a light pipe, wherein a gas-liquid heat exchanger is arranged above a shell body; a fed-liquid distributor is arranged below the shell body; a water distributor is arranged beside the water feeding cavity; and a thin-wall light pipe body or a thin-wall externally-pressed type heat exchange pipe body are characterized in that the wall thickness of the end of the light pipe body or the externally-pressed type heat exchange pipe body is larger than that of the main body. By the adoption of the scheme, the externally-pressed type heat exchange pipe distributor is simple in structure, the heat exchange efficiency of a thin-wall heat exchange pipe is maintained, and meanwhile the difficult problem of welding the heat exchange pipe to a pipe plate is solved.
Description
technical field [0001] The invention relates to heat exchange tubes, in particular to an external pressure heat exchange tube distributor. Background technique [0002] The heat exchange tubes on the existing heat exchangers generally use thin-walled tubes with a wall thickness of less than 3mm. It is difficult to ensure product quality for the welding between the heat exchange head and the tube sheet, which increases the production cost. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide an external pressure heat exchange tube distributor that can really play a sealing role. [0004] An external pressure heat exchange tube distributor, characterized in that it includes a shell, a water inlet cavity, an exchanger, and a light pipe, and a gas-liquid heat exchanger is arranged above the outer shell; Inlet distributor; the side of the water inlet chamber is equipped with a water separato...
