Problems solved by technology

[0003] The heat exchangers in the prior art are not resistant to freezing. In the process of freezing water into ice, the ice density is small and the volume expands, which often leads to vicious problems of heat exchanger swelling and cracking, which directly affects the operation and safety of the equipment.

Embodiment

[0020] refer to Figure 1 to Figure 7 , the invention discloses an anti-freezing heat exchanger with a three-dimensional air cavity, which is a shell-and-tube heat exchanger with metal tubes built in, and multi-channel parallel metal tubes are coiled in the shell to be connected to each other and formed by a large To a plurality of small concentric rings, the sleeves are used to isolate the adjacent rings, and it also has a brine outlet 1, a brine inlet 2, a liquid refrigerant outlet 3, and a gaseous refrigerant inlet 4.

[0021] The sleeve used to isolate the metal pipe can be made of a plurality of cups with a circular air cavity, or it can be made of an open cylinder as the base surface, and a series of rings that shrink at one end are sleeved , forming a series of air cavities, or superimposed special air cavities made by using the local gaps of the shell.

[0022] As a preferred air cavity, its top must be sealed, and its lower end cavity is open or has a gap or a hole t...

Abstract

The invention discloses a freeze-resistant type heat exchanger with a three-dimensional air cavity. The freeze-resistant type heat exchanger with the three-dimensional air cavity comprises a shell-and-tube type heat exchanger body and a plurality of concentric circular rings, wherein, the concentric circular rings are formed by the method that a multi-circuit parallel connection metal pipe is winded in the shell-and-tube type heat exchanger body, the concentric circular rings are mutually connected from big to small, and the adjacent circular rings are separated through sleeves. The freeze-resistant type heat exchanger with the three-dimensional air cavity has the beneficial effects that the freeze-resistant effect of the heat exchanger is achieved by building multi-loop passageways by using sleeves with different sizes and the air cavities, and big heat exchange amount is achieved through multi-loop heat exchanging in a small volume.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an antifreeze heat exchanger with a three-dimensional air cavity. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] The heat exchangers in the prior art are not resistant to freezing. During the process of freezing water into ice, the ice density is small and the volume expands, which often leads to vicious problems of heat exchanger swelling and cracking, directly affecting the operation and safety of the equipment. [0004] So the prior art needs to be improved and developed. Contents of the invention [0005] The technical problem to be solved by the invention is to provide a frost-resistant heat exchanger with a three-dimensional air cavity. [0006] The technical solution of the present invention is: an anti-freezing heat exchanger with a ...
