Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a plate-fin heat exchanger with an anti-blocking function. Background Art

[0002] The plate-fin heat exchanger is a common heat exchange equipment. The working principle of the plate-fin heat exchanger is to transfer heat by passing the heat source fluid and the cold source fluid through the two inlet pipes of the plate-fin heat exchanger respectively, so that the two fluids can exchange heat between the plates.

[0003] In the prior art, a Chinese patent with publication number CN217424078U discloses a plate-fin heat exchanger. By setting a mounting mechanism, it is convenient for workers to install or disassemble the heat exchanger, thereby promoting the convenience of later maintenance or replacement of the heat exchanger. By setting a first handle and a second handle, it is convenient for workers to take the heat exchanger, thereby further increasing the convenience of installing or disassembling the heat exchanger.

[0004] With respect to the related technologies of the above-mentioned patent, the inventors have found that the above-mentioned patent still has at least the following deficiencies: in the actual use of the plate-fin heat exchanger, the dirt and sediment in the fluid will gradually deposit on the wall of the flow channel as the fluid passes through the flow channel of the plate-fin heat exchanger. As time goes by, these scales will accumulate and block the flow channel, resulting in a decrease in heat exchange efficiency. The above-mentioned patent lacks a structure to prevent the flow channel from being blocked. After a period of time, the staff is required to disassemble the heat exchanger as a whole, clean the flow channel inside the heat exchanger, and then reinstall it. The operation is cumbersome and is not conducive to the long-term use of the plate-fin heat exchanger. Utility Model Content
