Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger that is heat-insulating and leak-proof. Background Technology

[0002] A heat exchanger is a device whose main function is to transfer heat from a hot fluid to a cold fluid. It is also called a heat exchanger. This device is widely used in industry, commerce and daily life. It is an industrial application that uses convection and heat conduction for heat transfer. The heat exchanger is equipped with an insulation and leak-proof structure to prevent leakage while keeping heat from being lost, thereby improving the performance of the heat exchanger.

[0003] The prior art, disclosed in patent document CN215261328U, presents the following technical solution: a heat exchanger with heat insulation and leak prevention, comprising a heat exchanger inner liner and a heat exchange tube bundle. The heat exchanger inner liner includes an inner liner body, a left cover, a right cover, and a connector. A medium inlet is provided on the upper left side of the heat exchanger inner liner. The heat exchange tube bundle is disposed inside the heat exchanger inner liner. The end of the fluid inlet away from the heat exchanger inner liner is connected to a first sleeve.

[0004] The above technical solution involves installing a filter screen inside the first sleeve at the fluid inlet. When the filter screen needs to be cleaned, the pipe at the fluid inlet needs to be disassembled first, which requires removing multiple bolts on the second flange. The first and second sleeves need to be separated by rotation to allow the filter screen to be exposed. The process is cumbersome and troublesome, reducing the efficiency of filter screen cleaning.

The heat exchanger can be insulated by the insulation board 12 and the vacuum layer 13.

[0031] like Figure 4 and Figure 5 As shown, the water inlet filter device 2 includes a mounting plate 22. A top cover 23 is fixedly connected to the top side of the mounting plate 22. L-shaped grooves 231 are provided around the top of the top cover 23 and the upper part of the mounting plate 22. Moving blocks 232 are slidably connected to the bottom side of the L-shaped grooves 231. A locking block 233 is fixedly connected to the outer end of the moving block 232. A spring 234 is embedded in the inner end of the moving block 232. The other end of the spring 234 is connected to the inner wall of the L-shaped groove 231. A connecting plate 235 is fixedly connected to the top side of the moving block 232. The connecting plate 235 extends to the upper part of the top cover 23. Anti-slip grooves 236 are provided on the opposite sides of the two connecting plates 235.
