Description

Technical Field

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

[0002] The inside of the electrolytic capacitor contains electrolyte material for storing charge, which is divided into positive and negative polarities, similar to batteries, and cannot be connected reversely. The positive electrode is a metal substrate with an oxide film, and the negative electrode is connected to the electrolyte through a metal plate. The non-polar electrolytic capacitor adopts a double oxide film structure, which is similar to two polar electrolytic capacitors connected with two negative electrodes.

The copper plate is annular, and its inner wall is tightly attached to the outer side of the capacitor body, and is used to conduct heat generated when the capacitor body is working. A spiral flow channel is opened in the inner cavity of the copper plate for the flow of cooling liquid. The stable heat dissipation capacitor has the advantages of high heat dissipation efficiency and strong practicality.

[0004] At present, although the existing heat dissipation type aluminum electrolytic capacitor elements can dissipate heat for the capacitor through the fan blades and the spiral flow channel, the coolant flowing in the spiral flow channel of the above patent needs to be connected to the external transmission pipe, so that the installation of a capacitor requires more space to place auxiliary equipment.

[0024] See also Figure 1-3A blowing member 120 is fixed on the top of the protective net 113, and the blowing member 120 includes a motor 121. The motor 121 is fixed on the top of the protective net 113. A rotating shaft 122 is fixed on the output shaft end of the motor 121. A fan blade 123 is fixed on one side of the rotating shaft 122. The fan blade 123 drives the air to blow toward the spiral tube 116, and then the air is discharged from the protective net 113. A rotating plate 124 is fixed at the end of the rotating shaft 122.

[0025] See also Figure 2-4 A liquid extraction structure 200 is fixed inside the shell 110, and the liquid extraction structure 200 includes a single-flow component 210 and a liquid extraction component 220. The single-flow component 210 is fixed inside the shell 110, and the liquid extraction component 220 is fixed inside the shell 110.

The conversion shell 211 is fixed inside the shell 110, and a support frame 212 is fixed inside the conversion shell 211. An elastic sheet 1 213 is fixed on one side of the support frame 212. The elastic sheet 1 213 and the elastic sheet 2 227 are both made of elastic materials. The reason why the elastic sheet 1 213 and the elastic sheet 2 227 can limit the flow direction of the coolant is similar to putting a plastic bag very close to the mouth and nose. At this time, when inhaling, the plastic bag will block the mouth and nose, but when blowing, the plastic bag will not block the flow of the blown air. The elastic sheet here One 213 and elastic sheet two 227 are equivalent to plastic bags, and the holes on the support frame 212 and the slide 225 are equivalent to the mouth and nose. A connecting pipe 214 is fixed on one side of the conversion shell 211, and the connecting pipe 214 can transport the cooling liquid in the conversion shell 211 to the liquid extraction shell 221.

The slide 225 is slidably connected to the inside of the liquid extraction shell 221. A support bar 226 is fixed inside the slide 225. The support bar 226 plays the role of fixing the elastic sheet two 227, and an elastic sheet two 227 is fixed on one side of the support bar 226.

[0026] Specifically, the working principle of the heat dissipation type aluminum electrolytic capacitor element is as follows: when in use, the motor 121 is started, and the motor 121 drives the fan blade 123, the fan blade 127 and the rotating plate 124 to rotate, so that the fan blade 123 draws air from the air inlet 111 and blows it to the spiral tube 116. When the rotating plate 124 rotates, it will drive the rotating rod 125 and the connecting shaft 126 to rotate, so that the fan blade 127 draws air from the air inlet 112 and blows it to the top of the capacitor body 119. At the same time, because the rotating rod 125 rotates and slides in the connecting frame 223, when the rotating rod 125 moves in a circle, the connecting frame 223 can perform a lateral reciprocating motion under the restriction of the driving rod 222, so that the driving rod 222 drives the slide 225 to reciprocate through the connecting rod 224, such as Figure 3 As shown, when the slide 225 moves to the left, in the case where the coolant cannot be pushed (Note: due to the cooperation of the support frame 212 and the elastic sheet 1 213 provided in the single-flow member 210, the flow direction of the coolant is unidirectional, so the coolant cannot be pushed), the coolant will push the elastic sheet 227 to enter the right side of the slide 225, and then when the slide 225 moves to the right, under the hydraulic state, the elastic sheet 227 will be tightly attached to the slide 225, so that the coolant cannot pass through the slide 225, so that as the slide 225 moves to the right, the coolant will flow into the connecting pipe 117, and then enter the spiral pipe 116. The coolant entering the spiral pipe 116 will have a long path to flow, and at this time, the fan blade 123 When blown toward the spiral tube 116, the coolant in the spiral tube 116 will gradually cool down, and finally flow from the infusion tube 118 into the conduit 115, and can absorb the heat transferred from the heat sink 114 to the capacitor body 119 through the conduit 115. Then, under the action of the pumping member 220, the coolant carrying the heat enters the spiral tube 116 again for cooling, thereby completing a cycle. At the same time, when the fan blade 127 draws air from the air inlet 112 and blows it toward the capacitor body 119, the air will also cool down the heat sink 114, and at the same time carry away the heat between adjacent heat sinks 114, and can also cool down the capacitor body 119, thereby ensuring that the capacitor body 119 does not generate high temperature accumulation during operation.

[0027] It should be noted that the specific model and specifications of the motor 121 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0028] The power supply and principle of the motor 121 are clear to those skilled in the art and will not be described in detail here.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
