Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a stable heat dissipation capacitor. Background Technology

[0002] A capacitor is a type of electronic component. It has multiple sets of electrodes inside. When opposite charges accumulate on the electrodes, energy can be stored in the circuit. The capacitance can be calculated using known values ​​of charge and voltage.

[0003] Because current flows when a capacitor is working, heat is generated when the internal electronic components operate. A structure is installed inside the capacitor to dissipate heat. A common heat dissipation structure involves installing a cooling fan and heat sink inside the capacitor. During operation, increasing the airflow speed inside the capacitor achieves heat dissipation. To ensure the stability of the heat sink during operation, a filter plate is installed outside the cooling fan to filter dust from the air, preventing dust from adhering to the heat sink and affecting its heat dissipation capacity. However, the filter plate is usually fixed with multiple sets of bolts, requiring the disassembly of the capacitor components and the removal of the old filter plate for replacement, which is very cumbersome. To solve this technical problem, this invention proposes a stable heat dissipation capacitor. Utility Model Content

[0004] The main objective of this invention is to provide a stable heat dissipation capacitor that can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stable heat dissipation capacitor includes a heat dissipation cylinder. Multiple sets of heat dissipation fins are fixedly installed on the inner wall of the heat dissipation cylinder. Multiple sets of heat dissipation pipes are connected to the inner wall of the heat dissipation cylinder. A main body module is disposed inside the heat dissipation cylinder. A cooling fan is fixedly installed inside the heat dissipation cylinder. A limiting plate is detachably connected to the inner wall of the heat dissipation cylinder. A limiting groove is formed inside the limiting plate. A fixing plate is slidably connected inside the limiting groove. A positioning hole is formed inside the fixing plate. A filter plate is fixedly installed inside the fixing plate. A moving rod is slidably connected inside the limiting plate. A positioning block is fixedly installed at one end of the moving rod. A spring is fixedly installed on the inner wall of the fixing plate.

[0007] Preferably, the bottom of the heat sink is detachably connected to a base, a protective mesh is fixedly installed inside the base, a protective shell is fixedly installed on the outer surface of the heat sink, and the heat dissipation pipe is located inside the protective shell.

[0008] Preferably, one end of the heat dissipation pipe is located in the middle of the heat dissipation cylinder, and the other end of the heat dissipation pipe is located above the heat dissipation fan. One end of each of the multiple sets of heat dissipation pipes is connected to a connecting cylinder, which is located above the heat dissipation fan.

[0009] Preferably, a baffle is fixedly installed on the outer surface of the fixing plate, and the outer surface of the baffle is slidably connected to the inside of the heat sink cylinder.

[0010] Preferably, the positioning block is a hemispherical structure, the outer surface of the positioning block is slidably connected to the inside of the positioning hole, and two sets of positioning blocks and positioning holes are provided on each side and arranged symmetrically.

[0011] Preferably, one end of the spring is connected to one end of the moving rod, and multiple sets of auxiliary plates are fixedly installed on the inner wall of the heat sink, with the outer surface of the fixed plate and the interior of the auxiliary plate being slidably connected.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the positioning block, the fixing plate, and the limiting plate work together. The limiting plate is installed on the inner wall of the heat dissipation cylinder. When the fixing plate is installed, the limiting groove can position the moving direction of the fixing plate, which facilitates the precise installation of the fixing plate. After the fixing plate enters the inside of the limiting groove, the spring pushes the positioning block into the inside of the positioning hole, which can limit the position of the fixing plate. This allows for the quick installation of the fixing plate and the filter plate. During installation, the new fixing plate is inserted along the direction of the limiting groove, which can push the old fixing plate to move out of the heat dissipation cylinder. This allows for the alternating replacement of the filter plates without first removing and then installing them, thus realizing the function of quick replacement of the filter plates and improving the efficiency of replacement.

[0014] This invention incorporates components such as heat dissipation pipes and cooling fans. The cooling fan ventilates the interior of the heat dissipation cylinder, accelerating airflow. Combined with the heat sink, it provides stable heat dissipation. Part of the airflow generated by the cooling fan moves upward through the heat sink, while another part is collected by the connecting cylinder and enters the heat dissipation pipe. The heat dissipation pipe then directs a portion of the airflow to the middle of the heat dissipation cylinder, ensuring uniform temperature distribution of the airflow on both the upper and lower sides of the cylinder. This prevents uneven temperature distribution caused by the airflow moving only from bottom to top, thus ensuring stable heat dissipation across the entire heat dissipation cylinder.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, a stable heat dissipation capacitor includes a heat dissipation cylinder 1. A base 14 is detachably connected to the bottom of the heat dissipation cylinder 1. Multiple sets of support legs are fixedly installed on the lower surface of the base 14 to facilitate the fixation of the base 14. By removing the base 14, the interior of the heat dissipation cylinder 1 can be inspected from below, which is convenient for operators to use. A protective net 15 is fixedly installed inside the base 14 to protect the bottom of the heat dissipation cylinder 1 and enhance its stability during use.

[0023] Multiple sets of heat sinks 2 are fixedly installed on the inner wall of the heat sink 1. The heat sinks 2 can dissipate heat from the inside of the heat sink 1. Multiple sets of heat dissipation pipes 3 are connected to the inner wall of the heat sink 1. One end of the heat dissipation pipe 3 is located in the middle of the heat sink 1. The heat dissipation pipe 3 can connect a portion of the air volume to the middle of the heat sink 1, which can process the internal heat dissipation air of the heat sink 1 and prevent the temperature from gradually increasing when the heat dissipation air flows from bottom to top. It can also prevent the heat dissipation air from reaching the main module 4 above, which has a high temperature and poor heat dissipation capacity. A protective shell 16 is fixedly installed on the outer surface of the heat sink 1. The heat dissipation pipes 3 are located inside the protective shell 16. The protective shell 16 can protect the heat dissipation pipes 3 that are exposed to the outside.

[0024] The heat sink 1 has a main module 4 inside, which includes pins and a capacitor body. A cooling fan 5 is fixedly installed inside the heat sink 1. The cooling fan 5 can ventilate the inside of the heat sink 1, which can accelerate the internal air circulation speed and improve the heat dissipation efficiency.

[0025] The other end of the heat pipe 3 is located above the cooling fan 5. One end of each of the multiple heat pipes 3 is connected to a connecting cylinder 17. The connecting cylinder 17 is located above the cooling fan 5. The connecting cylinder 17 can collect a portion of the cooling air generated by the cooling fan. At this time, a portion of the cooling air flows from bottom to top through the heat pipe 3, and a portion of the cooling air enters the interior of the heat pipe 3 after being collected by the connecting cylinder 17. The cooling air can be guided by the heat pipe 3 to the middle position of the heat pipe 1, improving the uniformity and stability of heat dissipation.

[0026] The inner wall of the heat sink 1 is detachably connected to a limiting plate 6. A limiting groove 7 is opened inside the limiting plate 6. A fixing plate 8 is slidably connected inside the limiting groove 7. The outer surface of the fixing plate 8 is slidably connected to the inside of the heat sink 1. The limiting groove 7 can guide the movement of the fixing plate 8, making it easy to quickly put the fixing plate 8 into the inside of the limiting plate 6. Multiple sets of auxiliary plates 19 are fixedly installed on the inner wall of the heat sink 1. The outer surface of the fixing plate 8 is slidably connected to the inside of the auxiliary plates 19. The limiting plates 6 and auxiliary plates 19 on both sides can limit the two sides of the fixing plate 8 and enhance the sealing of the fixing plate 8 during installation.

[0027] The fixed plate 8 has a positioning hole 9 inside, and a filter plate 10 is fixedly installed inside the fixed plate 8. A baffle 18 is fixedly installed on the outer surface of the fixed plate 8. The outer surface of the baffle 18 is slidably connected to the inside of the heat dissipation cylinder 1. The baffle 18 can seal the outside of the fixed plate 8 after installation to ensure the effect during use. The filter plate 10 can filter the heat dissipation air to ensure safety and stability during use.

[0028] The limiting plate 6 has a sliding connection to a moving rod 11. A positioning block 12 is fixedly installed at one end of the moving rod 11. The positioning block 12 is a hemispherical structure. The outer surface of the positioning block 12 is slidably connected to the inside of the positioning hole 9. Two sets of positioning blocks 12 and positioning holes 9 are arranged symmetrically on one side. After the positioning block 12 enters the inside of the positioning hole 9, it can fix the position of the fixing plate 8. A spring 13 is fixedly installed on the inner wall of the fixing plate 8. One end of the spring 13 is connected to one end of the moving rod 11. The spring 13 can assist the positioning block 12 in fixing and can generate a pushing force on the positioning block 12. When installing the fixing plate 8, the fixing plate 8 is inserted. At this time, under the action of the spring 13, the positioning block 12 can enter the inside of the positioning hole 9 and fix the position of the fixing plate 8. When replacing the filter plate 10, the new fixing plate 8 is inserted along the direction of the limiting plate 6. The old filter plate 10 can be pushed out and the new filter plate 10 can be inserted and fixed. The installation is very convenient and does not require disassembly of the whole.

[0029] When replacing the filter plate 10, the new fixing plate 8 is inserted along the direction of the limiting plate 6. The external fixing plate 8 can push the internal fixing plate 8 of the heat dissipation cylinder 1 to move. At this time, the positioning block 12 can disengage from the positioning hole 9 under the movement of the fixing plate 8, and can push out the internal fixing plate 8 of the heat dissipation cylinder 1. At this time, the new fixing plate 8 enters the interior of the limiting groove 7. Under the push of the spring 13, the positioning block 12 enters the interior of the positioning hole 9 and can fix the two sides of the fixing plate 8. When working, the cooling fan can draw external air into the interior of the heat dissipation cylinder 1. Part of the cooling air flows from bottom to top through the heat dissipation fins 2, and the other part of the cooling air enters the interior of the heat dissipation pipe 3 after being collected by the connecting cylinder 17 and flows into the middle position of the heat dissipation pipe 3. This can prevent the temperature from gradually increasing and the cooling effect from decreasing due to the single cooling air flowing from bottom to top.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
