[0034] Reference Figure 4-Figure 6 The groove 5 is provided on the surface of the heat exchange frame 1, the outer wall of the filter frame 8 is adapted to the inner wall of the heat exchange frame 1, and the disassembly assembly includes a mounting groove 10, the inner wall of the mounting groove 10 is fixedly connected with a telescopic rod 11, and the outer wall of the telescopic rod 11 is sleeved with a telescopic spring 12, and the elastic force of the telescopic spring 12 can drive the fixed block 13 to always maintain the position at the lower end of the mounting groove 10 through the telescopic rod 11, the bottom end of the telescopic spring 12 is fixedly connected with a fixed block 13, and the bottom of the fixed block 13 is provided with an embedding groove 14, and the outer wall of the filter frame 8 is fixedly connected with a plug plate 15, and the plug plate 15 is magnetically connected to the fixed block 13, and the upper surface of the plug plate 15 is fixedly connected There is an embedded block 16, and the limiting assembly includes a limiting plate 17. A through hole 18 is opened on the surface of the limiting plate 17. The outer wall of the heat exchange frame 1 is rotatably connected with a rotating rod 19, and the outer wall of the rotating rod 19 is fixedly connected to the limiting block 20. The rotating rod 19 is inserted into the through hole 18 and rotated ninety degrees. The limiting block 20 and the through hole 18 are staggered, so that the limiting plate 17 cannot be separated from the limiting block 20. The mounting groove 10 is opened on the side of the fixed plate 7 close to the filter frame 8. The outer wall of the plug plate 15 is adapted to the inner wall of the mounting groove 10, and the inner wall of the embedded groove 14 is adapted to the outer wall of the embedded block 16.

[0035] Reference Figure 3 A slide groove 21 is provided on the upper surface of the heat exchange frame 1, and two groups of slide grooves 21 are provided, and the two groups of slide grooves 21 are symmetrically arranged with the central axis of the cooling fan 4 as the symmetry axis.

[0036] Working principle: the filter screen 9 is used to prevent dust on both sides of the heat exchange frame 1. When the filter screen 9 needs to be cleaned, firstly, the rotating rod 19 is reversed by 90 degrees so that the limit block 20 and the through hole 18 are aligned, and the filter frame 8 will be out of position. Force is applied to the filter frame 8 to make it rotate around the center point of the rotating shaft 6. The filter frame 8 is now away from the inside of the heat exchange frame 1. The heat exchange frame 1 is in an open state. The filter frame 8 is manually lifted upward, and the telescopic rod 11 and the telescopic spring 12 are stressed. The plug plate 15 squeezes the fixed block 13 and moves upward in the installation groove 10. Then, the filter frame 8 is forced outward, and the embedding block 16 is out of the embedding groove 14, so that the filter frame 8 is separated from the heat exchange frame 1, which is convenient for cleaning the filter screen 9. After the filter screen 9 is cleaned, the above steps are reversed. The filter frame 8 is installed on the heat exchange frame 1, and the filter screen 9 is used to close the open part of the heat exchange frame 1 by rotating the rotating shaft 6, so as to prevent dust from adhering to the base tube 2 and the fin 3. At the same time, the protective plate 25 provides protection for the cooling fan 4. When objects fall from a high place outside, the objects will hit the protective plate 25. At this time, the two groups of support rods 24 will drive the moving block 22 to slide toward the opposite side in the two groups of slide grooves 21 respectively, and the reset spring 23 is compressed by force. The protective plate 25 prevents the objects from causing damage to the cooling fan 4. When the external impact force is eliminated, the elastic force of the reset spring 23 will drive the moving block 22 to reset. At the same time, the air inlet 26 can prevent the protective plate 25 from blocking the air intake when it is close to the cooling fan 4, thereby ensuring the use effect of the heat exchanger.
