Description

Technical Field

[0001] This utility model relates to plate-fin heat exchangers, and more particularly to a plate-fin heat exchanger nozzle reinforcement device. Background Technology

[0002] Plate-fin heat exchangers are highly efficient heat exchange devices widely used in various industrial fields. They consist of parallel-arranged metal plates and heat exchange fins, achieving heat exchange through the increased surface area of ​​the fins and forced convection of the fluid. During the use of plate-fin heat exchangers, connecting pipes are needed to guide the fluid to the inlet and outlet pipes of the heat exchanger.

[0003] The existing technology has the following problems: In actual use, the connecting pipes of existing plate-fin heat exchangers need to circulate liquid inside. When the connecting pipes are affected by the liquid, they will shake. When the connecting pipes shake, it will affect the connection stability between the connecting pipes and the plate-fin heat exchanger, thus affecting the normal use of the plate-fin heat exchanger. Utility model CN220567964U discloses a plate-fin heat exchanger body, with a connecting pipe body on one side of the plate-fin heat exchanger body. The outer surface of the connecting pipe body is provided with an anti-corrosion layer, and the inner wall of the anti-corrosion layer is provided with a first fiber strip. A second fiber strip is provided on one side of the first fiber strip. A support plate is provided inside the connecting pipe body. The surface is provided with a fixing groove, and a pressure spring is installed inside the fixing groove. A slider is installed at one end of the pressure spring. This utility model, through the fixing groove, pressure spring, slider, and claw, allows the position of the claw to be adjusted by the cooperation of the pressure spring and slider inside the fixing groove when the plate-fin heat exchanger body is in use. This allows the claw to clamp and fix the pipe body, thereby improving the stability of the pipe body and preventing it from shaking due to the liquid flowing inside. Although the pipe can be pressed down by the pressure spring, the spring will vibrate when shaking occurs, resulting in poor fixing effect and only being compatible with pipes of one diameter.
