[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0026] like Figure 1-Figure 4As shown, this embodiment provides a technical solution: a heat-resistant capacitor, comprising a shell 1, wherein two pins 2 are arranged on the top of the shell 1; a heat dissipation protection structure 3 is arranged on the bottom of the outer surface of the shell 1; an auxiliary cleaning structure 4 is arranged on the bottom of the heat dissipation protection structure 3; the heat dissipation protection structure 3 comprises a heat dissipation water pipe 31 and a rectangular protection frame 36, the heat dissipation water pipe 31 is divided into an outer section and an inner section, the inner section of the heat dissipation water pipe 31 is fixedly installed with the inside of the shell 1, the outer section of the heat dissipation water pipe 31 is arranged at the bottom of the shell 1 and is curved, the outer surface bottom of the shell 1 is fixedly connected with a rectangular card frame 32, and both sides of the rectangular protection frame 36 A filter mesh 37 is provided, and L-shaped protective plates 311 are fixedly connected to both sides of the outer surface of the rectangular protective frame 36. By setting the heat dissipation water pipe 31, the inner section and the outer section of the heat dissipation water pipe 31 cooperate with each other to assist in the heat dissipation of the heat inside the shell 1, thereby avoiding the excessive temperature inside the shell 1 causing accelerated aging of the capacitor, thereby increasing its service life. At the same time, under the action of the rectangular clamping frame 32 and the rectangular clamping block 39, the rectangular protective frame 36 can be fixed to the shell 1, thereby protecting the outer section of the heat dissipation water pipe 31, avoiding the outer section of the heat dissipation water pipe 31 from being exposed and then being damaged by impact.

[0027] Further, such as Figure 4 As shown: a rectangular card frame 32 is fixedly connected to the bottom of the outer surface of the shell 1, and rectangular through holes 38 are opened on both sides of the outer surface of the rectangular protective frame 36. The top of the rectangular card frame 32 is located on both sides of the rectangular through holes 38 and is fixedly connected with rectangular card blocks 39. The rectangular card blocks 39 can be stuck into the inner wall of the rectangular card frame 32. The inner walls of both sides of the rectangular card frame 32 are opened with first round through holes 33, and the inner wall of the rectangular card block 39 is opened with second round through holes 310. The inner walls of the first round through holes 33 and the second round through holes 310 are both inserted with threaded plug rods 34, and one end of the threaded plug rod 34 is threadedly connected with a fixing nut 35. Under the action of the heat dissipation water pipe 31, the coolant inside the heat dissipation water pipe 31 can dissipate the heat inside the shell 1 by heat transfer. The heat dissipation section exposed to the outside makes the heat dissipation effect better. At the same time, under the action of the rectangular card frame 32 and the rectangular card block 39, the rectangular protective frame 36 can be installed to protect the heat dissipation water pipe 31.

[0028] The above solution also has the problem that dust easily accumulates on the outer surface of the filter mesh 37, thereby affecting the heat dissipation. Figure 3As shown: in the present scheme, the auxiliary cleaning structure 4 includes a rectangular frame 41 and a brush plate 49. The top of the outer surface of the rectangular frame 41 is fixedly connected to the bottom of the outer surface of the rectangular protective frame 36. A fixing rod 42 is fixedly connected between the two sides of the inner wall of the rectangular frame 41. The outer surface of the fixing rod 42 is slidably connected with a rectangular slider 43. The rectangular slider 43 is slidably connected to the inner wall of the rectangular frame 41. The bottom of the outer surface of the rectangular slider 43 is fixedly connected with an operating rod 44. Rectangular through-slide grooves 45 are provided on the inner walls of the two sides of the rectangular frame 41. The inner wall of the rectangular through-slide groove 45 is slidably connected with an L-shaped slide rod 46. One end of the L-shaped slide rod 46 is fixedly connected to one side of the rectangular slider 43. Under the action of the rectangular frame 41, the rectangular slider 43 and the operating rod 44 can be used to drive the brush plate 49 to move, so that the brush plate 49 can clean the dust adhered to the filter mesh 37.

[0029] The above scheme still has the problem that the brush plate 49 will be aged and unusable if it is used continuously. Figure 4 As shown, one end of the L-shaped sliding rod 46 away from the rectangular sliding block 43 is fixedly connected to a rectangular locking frame 47, the inner wall of the rectangular locking frame 47 is clamped with a rectangular locking block 48, the outer surface of the rectangular locking block 48 is fixedly connected to the brush plate 49, the inner walls of the two sides of the rectangular locking frame 47 are provided with a first circular hole 410, the inner wall of the rectangular locking block 48 is provided with a second circular hole 411, and the inner walls of the first circular hole 410 and the second circular hole 411 are inserted with a circular insertion rod 412. Under the action of the rectangular locking block 48 and the rectangular locking frame 47, the brush plate 49 can be disassembled and assembled in cooperation with the circular insertion rod 412, thereby facilitating the maintenance and replacement of the brush plate 49.

[0030] Working principle:

[0031] like Figure 1-4 As shown:

[0032] When in use: fix the rectangular clamp block 39 with the rectangular clamp frame 32, insert the threaded rod 34 into the inner wall of the first round through hole 33 and the second round through hole 310 in sequence, and fix the fixing nut 35 with the threaded rod 34. At this time, the rectangular protection frame 36 can protect the heat dissipation water pipe 31, and the filter mesh 37 will not affect the heat dissipation effect of the heat dissipation water pipe 31. At this time, the heat inside the housing 1 can be dissipated in the heat dissipation water pipe 31;

[0033] When the filter mesh 37 needs to be cleaned, the operating rod 44 is pushed, so that the rectangular slider 43 slides on the inner wall of the rectangular frame 41 and the outer surface of the fixing rod 42, thereby driving the brush plate 49 to move, thereby cleaning the filter mesh 37;

[0034] When the brush plate 49 needs to be replaced, the circular insertion rod 412 is pulled out of the inner walls of the first circular insertion hole 410 and the second circular insertion hole 411, and the brush plate 49 is pulled upward to separate the rectangular locking block 48 from the rectangular locking frame 47, thereby completing the disassembly.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
