Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of aluminum electrolytic capacitors, in particular to a heat dissipation type aluminum electrolytic capacitor. Background Art

[0002] Aluminum electrolytic capacitors are capacitors made of an aluminum cylinder as the negative electrode, filled with liquid electrolyte, and a curved aluminum strip inserted as the positive electrode. It is a general-purpose electrolytic capacitor made of aluminum material with good electrical performance, wide application range, and high reliability. Due to its low cost, aluminum electrolytic capacitors have always been a common choice for power supplies.

[0003] In the prior art, when the aluminum electrolytic capacitor is working in a low-voltage state, it is generally cooled naturally through air ventilation, which can ensure that the aluminum electrolytic capacitor works at a suitable temperature. In a high-voltage state, heat is generally dissipated by means of a heat sink, wherein the heat is conducted through the heat sink and a heat dissipation fan is used for heat dissipation. However, when in use, the aluminum electrolytic capacitor is placed among multiple components of the circuit. When the heat dissipation fan is dissipating heat, it cannot dissipate heat for the aluminum electrolytic capacitor alone, and when the external ambient temperature is high, the heat dissipation efficiency of the heat dissipation fan is reduced. As the components in the high-voltage circuit are continuously used, the temperature will gradually increase, thereby causing the heat dissipation effect of the heat sink installed on the aluminum electrolytic capacitor to gradually decrease. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a heat dissipating aluminum electrolytic capacitor so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A heat dissipation type aluminum electrolytic capacitor comprises a shell, an aluminum electrolytic capacitor body is installed in the shell, an outer spiral pipe is installed between the aluminum electrolytic capacitor body and the inner wall of the shell, the top side of the outer spiral pipe is connected to a rotating pipe, the other end of the rotating pipe extends into the side wall of the shell and is connected to a heat dissipation pipe, the heat dissipation pipe extends downward to the inner bottom of the side wall of the shell, and the inner bottom of the shell is connected to an auxiliary component.

[0007] By adopting the above technical solution, the auxiliary component is arranged to cooperate with the outer spiral pipe, and the coolant is injected into the outer spiral pipe. Then, the wind is transported by the external cooling fan and utilized through the auxiliary component, and the coolant in the outer spiral pipe is circulated and heat is exchanged with the outside, so as to take away the heat of the aluminum electrolytic capacitor body, achieve the effect of self-heating, and then achieve the effect of independently cooling the aluminum electrolytic capacitor body, preventing the aluminum electrolytic capacitor body from being affected by the external temperature and causing the temperature of the aluminum electrolytic capacitor body to rise.

[0008] In a preferred example, the utility model can be further configured as follows: the auxiliary component includes a bottom partition, the bottom partition is installed on the bottom of the shell, a driving shaft is rotatably installed in the middle of the bottom side of the bottom partition, a number of air guide plates are connected to the outer side of the driving shaft, an air guide duct is arranged on the outer side of the air guide plate, the air guide duct is spirally arranged, and the air guide duct is fixedly connected to the bottom partition.

[0009] By adopting the above technical solution, an air guide duct is arranged on the bottom side of the bottom partition. After the wind enters the air guide duct, it is transported and blown to the air guide vanes through the air guide duct, thereby driving the air guide vanes to rotate, thereby achieving the effect of transmission within the auxiliary component.

[0013] By adopting the above technical solution, the bottom spiral pipe is arranged to cooperate with the outer spiral pipeline and the bottom connecting pipe to circulate the coolant, and the effect of driving the coolant to flow is achieved through the rotation of the spiral blades.

[0014] In a preferred example, the utility model can be further configured as follows: a heat exchange groove is formed on the outer wall of the shell at the heat dissipation pipe, and the heat dissipation pipe is located in the heat exchange groove.

[0015] By adopting the above technical solution, the heat exchange groove is set to expose the heat dissipation pipe when dissipating heat, so that the coolant in the heat dissipation pipe absorbs the aluminum electrolytic capacitor body and then exchanges heat in the heat dissipation groove, thereby reducing the temperature of the coolant and facilitating recycling.

[0016] In a preferred example, the utility model can be further configured as follows: a support plate is connected to the bottom end of the shell, and the top side of the support plate is in contact with the bottom side of the air duct.

[0017] By adopting the above technical solution, the support plate is used to protect the air duct at the bottom of the shell, and at the same time protect the shell to prevent air leakage.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. This heat dissipation aluminum electrolytic capacitor allows the aluminum electrolytic capacitor body to dissipate heat without being affected by the external temperature, and allows the aluminum electrolytic capacitor body to dissipate heat independently, so that when dissipating heat, the heat dissipation effect of the aluminum electrolytic capacitor body will not be affected by the external temperature change;

[0020] 2. This heat dissipation type aluminum electrolytic capacitor is provided with a bottom spiral tube, which can cool and dissipate the bottom of the aluminum electrolytic capacitor body after the coolant enters. Therefore, when the drive shaft rotates, the coolant in the heat dissipation tube will be transported to the bottom spiral tube through the bottom connecting tube, and then transported from the other end of the bottom spiral tube to the outer spiral tube for circulation, thereby achieving the effect of circulation when the coolant is cooling and dissipating heat.
