The heat sink is fixed with two front and rear distributed fixing plates, each of the fixing plates is hinged with a handle, and each of the side walls of the slot is provided with a locking ball, and the locking ball can be engaged with the heat sink, and the inner end of the protective shell is fixed with a guide slide plate abutting the fixing plate, and the extension direction of the guide slide plate is the same as that of the fixing sleeve and the heat sink, and both extend forward and backward, and the mutually distant ends of the front and rear adjacent fixing plates are fixed with insertion rods, and the mutually distant ends of the two front and rear adjacent guide slides are fixed with positioning plates, and the positioning plate is provided with a hole abutting the insertion rod.

[0005] The beneficial effects of the utility model are:

[0006] It is easy to disassemble and install. The heat sink is connected to the slot through the thermal expansion of the card ball. No welding is required to achieve a stable effect. It is protected by a protective shell to further improve the stability of the heat sink. The heat sink that is too long can be replaced freely to remove dust accumulated on the heat sink. The protection of the protective shell and the heat dissipation of the heat dissipation cavity can reduce dust accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0018] Reference Figure 1-Figure 7According to an embodiment of the utility model, an inverter protective housing includes two protective housings 10 distributed front and back and a mounting housing 11 located inside the protective housing 10. The two protective housings 10 are spliced ​​and arranged at the ends close to each other. The ends of the two protective housings 10 far from each other and the four corners of the inner end of the protective housing 10 are fixed with mounting blocks 19. The mounting blocks 19 are provided with threaded mounting holes. The inner end of the mounting housing 11 is fixed with evenly distributed fixing sleeves 13. The mounting housing 11 and the fixing sleeve 13 are provided with card slots 18 opened and arranged away from the center end of the fixing sleeve 13. Each card slot 18 is inserted into a heat sink 14. Two front-to-back distributed fixing plates 15 are fixedly provided on the heat sink 14 on the side, and a handle 22 is hinged on each fixing plate 15. A card ball 17 is provided on the side wall of each card slot 18, and the card ball 17 can be carded with the heat sink 14. A guide slide plate 16 abutting against the fixing plate 15 is fixedly provided at the inner end of the protective shell 10. The extension direction of the guide slide plate 16 is the same as that of the fixing sleeve 13 and the heat sink 14, and both extend forward and backward. The ends of the front and rear adjacent fixing plates 15 away from each other are fixedly provided with an insertion rod 21, and the ends of the two front and rear adjacent guide slide plates 16 away from each other are fixedly provided with a positioning plate 20, and a plug hole is opened on the positioning plate 20 to abut against the insertion rod 21;
