Abstract

The invention discloses a channel assembly. The channel assembly comprises a shell which is matched with a tube plate, wherein a current sharing tube with the sealed inner end part is arranged in the middle of the shell; a plurality of first-stage current sharing holes are formed in the sealing surface and side wall of the current sharing tube; a refrigerant air outlet tube and a refrigerant liquid inlet tube which is coaxially communicated with the current sharing tube axially penetrate the shell; a current sharing plate which is matched with the current sharing tube is arranged on the end surface of the shell, which is matched with the tube plate; and a plurality of second-stage current sharing holes which are in one-one-to-one correspondence with heat exchange tubes of the tube plate and adapt to the heat exchange tubes mutually are arranged on the current sharing plate. The channel assembly can improve the heat exchange efficiency of a dry-type evaporator and causes the overall operation of the dry-type evaporator to be relatively stable and efficient. The invention also discloses the dry-type evaporator adopting the channel assembly.

Description

technical field [0001] The invention relates to the technical field of dry evaporator supporting components, in particular to a pipe box assembly. The invention also relates to a dry evaporator using the pipe box assembly. Background technique [0002] In the current field of refrigeration equipment, the dry evaporator, as an indispensable part of the entire refrigeration system, plays a vital role in the entire refrigeration system, and the tube box assembly is an important part of the dry evaporator, Its working performance directly affects the overall working condition of the dry evaporator. With the continuous improvement of the demand for use, people have put forward higher requirements for the working performance of the dry evaporator. [0003] At present, in the existing dry evaporator, the tube box assembly is usually equipped with a flow equalizer to ensure that the refrigerant can evenly enter the heat exchange tubes on the tube sheet, and thus ensure the overall...
