Description

Technical Field

[0001] The present application relates to the technical field of heat sinks, and in particular to capacitor heat sinks. Background Art

[0002] A capacitor is an electronic component used to store and release electrical energy in a circuit. A capacitor consists of two conductive metal plates (usually metal foil or metallized film) with an insulating medium (called a dielectric or dielectric) between the two plates. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge, and the capacitance of the capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates.

[0003] Capacitors generate heat when in use. In order to better dissipate heat, capacitors are usually packaged in aluminum shells or spray-coated iron shells. However, with the rapid development of industry, there are a large number of harmonics in the power grid. A single capacitor will amplify the harmonics, increasing the operating current and causing the capacitor to generate more heat. The current electric heater has poor heat dissipation capacity, which can easily lead to damage to the capacitor. Summary of the invention

[0004] In order to improve the heat dissipation capability of a capacitor, the present application provides a capacitor heat sink.

[0005] The capacitor radiator provided in this application adopts the following technical solution:

[0006] A capacitor radiator comprises a capacitor, wherein a heat dissipation component is arranged on the outer wall of the capacitor, wherein the heat dissipation component comprises a connecting hoop and fins, wherein the connecting hoop is detachably fixed to the outer wall of the capacitor, the fins are mounted on the outer wall of the connecting hoop, and the fins are arranged along the circumference of the connecting hoop.

[0007] By adopting the above technical solution, the heat of the capacitor is transferred to the connecting hoop and the fins. Under the action of the fins, the surface area of ​​heat dissipation is increased, so that the contact between the air and the heat source is more complete, thereby improving the heat exchange efficiency, accelerating the heat transfer, and further improving the heat dissipation effect of the capacitor. The fins are installed on the outer wall of the connecting hoop, and the connecting hoop and the capacitor are detachably fixedly connected, thereby facilitating the disassembly and assembly between the heat dissipation component and the capacitor. When the heat dissipation component is damaged, it is convenient to replace or repair the heat dissipation component.

[0008] Preferably, the connecting hoop includes two connecting blocks, one end of the two connecting blocks are hinged, the inner walls of the two connecting blocks are pressed against the outer wall of the capacitor, and a connecting piece is provided between the other ends of the two connecting blocks, and the connecting piece fixes one end of the two connecting blocks.

[0009] By adopting the above technical solution, when the heat dissipation assembly needs to be disassembled from the capacitor, the connecting piece between the two connecting blocks is first loosened, and then opposite forces are applied to the two connecting blocks to increase the capacity cavity between the two connecting blocks, and finally an upward force is applied to the heat dissipation assembly to remove the heat dissipation assembly from the capacitor, thereby improving the convenience of disassembly and assembly between the heat dissipation assembly and the capacitor.

[0010] Preferably, the fin comprises fin bars, the fin bars are vertically fixed along the connecting block, there are a plurality of fin bars, the plurality of fin bars are distributed along the circumferential direction of the connecting block, and a ventilation slot is provided between two adjacent fin bars.

[0011] By adopting the above technical solution, multiple fins increase the heat dissipation surface area of ​​the capacitor, accelerate the heat transfer, and under the action of the ventilation slots, the air flow distribution can be optimized, the resistance of air flow can be reduced, and the heat dissipation effect of the capacitor can be improved.

[0012] Preferably, the wing strip is an isosceles trapezoidal strip, and the width of the wing strip at one end close to the connecting block is greater than the width of the wing strip at one end away from the connecting block.

[0013] By adopting the above technical solution, the width of the wing near the connecting block is greater than the width of the wing away from the connecting block, thereby increasing the connection area with the connecting block and improving the connection stability between the wing and the connecting block. At the same time, the force area between the wing and the connecting block can be increased, and the center of gravity of the wing can be lowered, so that when the wing is subjected to force, the wing can be less likely to fall off the connecting block. At the same time, the surface area for heat dissipation is further increased.

[0014] Preferably, there are multiple heat dissipation components, and the multiple heat dissipation components are distributed along the long side direction of the capacitor.

[0015] By adopting the above technical solution, under the action of multiple heat dissipation components, more parts of the outer wall of the capacitor are covered by the heat dissipation components, thereby achieving a better heat dissipation effect of the capacitor.

[0016] Preferably, a connecting rod is detachably connected between two adjacent heat dissipation components.

[0017] By adopting the above technical solution, when multiple heat dissipation components need to be disassembled from the capacitor, the bolts connecting each heat dissipation component are first loosened, and then opposite forces are applied to the two connecting blocks of one of the connecting hoops, thereby increasing the storage cavity. Under the action of the connecting rod, the storage cavities of other connecting hoops can also be driven to increase. Finally, an upward force is applied to the heat dissipation component, so that multiple heat dissipation components can be taken out of the capacitor at the same time. Accordingly, when multiple heat dissipation components need to be installed on the outer wall of the capacitor, multiple heat dissipation components can be simultaneously sleeved on the outer wall of the capacitor, and multiple connecting rods connect the multiple heat dissipation components together, thereby improving the convenience of disassembly and assembly of multiple heat dissipation components, reducing the time for installing or disassembling multiple heat dissipation components, and at the same time, also reducing the time for adjusting the distance between two adjacent heat dissipation components. The connection between the connecting rod and the heat dissipation component is a detachable connection, which is convenient for operating when one of the heat dissipation components needs to be repaired or replaced.

[0018] Preferably, installation grooves are respectively provided at the top and bottom of the outer wall of the connecting block, and the installation grooves at the bottom of the upper connecting block and the top of the lower connecting block of the two adjacent upper and lower connecting blocks correspond to the installation grooves, and the two ends of the connecting rod are respectively adapted to be inserted into the installation grooves adjacent thereto.

[0019] By adopting the above technical solution, the two ends of the connecting rod are respectively inserted into the installation grooves of the upper and lower adjacent connecting blocks, so that the connection between the upper and lower connecting blocks is achieved by plugging the connecting rod into the two installation grooves, thereby improving the convenience of disassembly and assembly between the two connecting blocks.

[0020] Preferably, the connecting rod is an I-shaped rod.

[0021] By adopting the above technical solution, the connecting rod is an "I"-shaped rod, thereby increasing the contact area with the connecting block, thereby increasing the friction between the connecting rod and the connecting block, improving the connection stability between the connecting rod and the connecting block, and reducing the situation where the connecting rod is separated from the connecting block. In addition, the connecting rod is interlocked with the connecting block. When the connecting rod is subjected to upward or downward force, the connecting block can provide supporting force for the connecting rod, thereby further reducing the situation where the connecting rod is separated from the connecting block. The connection between the connecting rod and the connecting block is a detachable connection, which facilitates operation when one of the heat dissipation components needs to be repaired or replaced.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The heat of the capacitor is transferred to the connecting hoop and the fins. Under the action of the fins, the surface area of ​​heat dissipation is increased, so that the contact between the air and the heat source is more complete, thereby improving the heat exchange efficiency, accelerating the heat transfer, and further improving the heat dissipation effect of the capacitor. The fins are installed on the outer wall of the connecting hoop, and the connecting hoop and the capacitor are detachably fixedly connected, so as to facilitate the disassembly and assembly between the heat dissipation component and the capacitor. When the heat dissipation component is damaged, it is convenient to replace or repair the heat dissipation component.

[0024] 2. When multiple heat dissipation components need to be disassembled from the capacitor, first loosen the bolts connecting each heat dissipation component, then apply opposite forces to the two connecting blocks of one of the connecting hoop, thereby increasing the storage cavity. Under the action of the connecting rod, the storage cavity of other connecting hoop can also be driven to increase. Finally, apply upward force to the heat dissipation component to remove multiple heat dissipation components from the capacitor at the same time. Correspondingly, when multiple heat dissipation components need to be installed on the outer wall of the capacitor, multiple heat dissipation components can be simultaneously sleeved on the outer wall of the capacitor, and multiple connecting rods connect the multiple heat dissipation components together, thereby improving the convenience of disassembly and assembly of multiple heat dissipation components, reducing the time for installing or disassembling multiple heat dissipation components, and at the same time, also reducing the time for adjusting the distance between two adjacent heat dissipation components. The connection between the connecting rod and the heat dissipation component is a detachable connection, which is convenient for operation when one of the heat dissipation components needs to be repaired or replaced.

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiments of the present application disclose a capacitor heat sink.

[0030] Reference Figure 1A capacitor radiator comprises a capacitor 1, a heat dissipation assembly 2 is arranged on the outer wall of the capacitor 1, the heat dissipation assembly 2 comprises a connecting hoop 21, the connecting hoop 21 comprises a connecting block 211, there are two connecting blocks 211, one end of the two connecting blocks 211 is hinged, the inner walls of the two connecting blocks 211 are in contact with the outer wall of the capacitor 1, a connecting piece is arranged between the other ends of the two connecting blocks 211, in the embodiment of the present application, the connecting piece is a bolt 22, one end of the bolt 22 passes through one side of the two connecting blocks 211 at the same time, the bolt 22 fixes one end of the two connecting blocks 211, a storage cavity is formed between the two connecting blocks 211, the capacitor 1 is located in the storage cavity, and the size of the storage cavity can be controlled during the process of tightening the two connecting blocks 211 with the bolt 22 until the two connecting blocks 211 are fixed to the outer wall of the capacitor 1.

[0031] Reference Figure 1 and Figure 2 The heat dissipation component 2 also includes a fin 23, and there are two fins 23. The two fins 23 are distributed on the outer walls of the two connecting blocks 211. The fin 23 includes a fin 231. The fin 231 is fixed to the outer wall of the connecting block 211, and the fin 231 is arranged along the vertical direction of the connecting block 211. In the embodiment of the present application, the fin 231 is an isosceles trapezoidal fin, and the width of the fin 231 close to the connecting block 211 is greater than the width of the fin 231 away from the connecting block 211. The connection area with the connecting block 211 can be increased, and the connection stability between the fin 231 and the connecting block 211 can be improved. At the same time, the force area between the fin 231 and the connecting block 211 can be increased, and the center of gravity of the fin 231 can be lowered, so that when the fin 231 is subjected to a force, the fin 231 can be reduced. The situation of falling off from the connecting block 211 can be reduced. There are multiple fins 231, and the multiple fins 231 are evenly distributed along the circumferential direction of the connecting block 211.

[0032] A ventilation groove 232 is arranged between two adjacent fins 231. The ventilation groove 232 is an isosceles trapezoidal groove. The width of the outer end of the ventilation groove 232 is greater than the width of the inner end of the ventilation groove 232. The heat of the capacitor 1 is transferred to the connecting block 211 and the fin 23. Under the action of the fin 23, the surface area of ​​heat dissipation is increased, so that the contact between the air and the heat source is more complete, thereby improving the heat exchange efficiency and accelerating the heat transfer. Under the action of the ventilation groove 232, the air flow distribution can be optimized, the resistance of air flow can be reduced, and the heat dissipation effect of the capacitor 1 can be improved.

Under the action of the multiple heat dissipation components 2, more parts of the outer wall of the capacitor 1 are covered by the heat dissipation components 2, thereby making the heat dissipation effect of the capacitor 1 better.

[0034] The top and bottom of the outer wall of the connecting block 211 are respectively provided with mounting grooves 212.

[0035] When multiple heat dissipation components 2 need to be disassembled from the capacitor 1, first loosen the bolts 22 connecting each heat dissipation component 2, and then apply opposite forces to the two connecting blocks 211 of one of the connecting hoops 21, so as to enlarge the storage cavity. Under the action of the connecting rod 3, the storage cavity of other connecting hoops 21 can also be enlarged. Finally, apply an upward force to the heat dissipation component 2, so as to remove the multiple heat dissipation components 2 from the capacitor 1 at the same time. Accordingly, when multiple heat dissipation components 2 need to be installed on the outer wall of the capacitor 1, the multiple heat dissipation components 2 can be simultaneously sleeved on the outer wall of the capacitor 1, and the multiple connecting rods 3 connect the multiple heat dissipation components 2 together, thereby improving the convenience of disassembly and assembly of the multiple heat dissipation components 2, reducing the time for installing or disassembling the multiple heat dissipation components 2, and at the same time, also reducing the time for adjusting the distance between two adjacent heat dissipation components 2.

[0036] Reference Figure 1 In the embodiment of the present application, the connecting rod 3 is an I-shaped rod, so that the contact area with the connecting block 211 can be increased, thereby increasing the friction between the connecting rod 3 and the connecting block 211, improving the connection stability between the connecting rod 3 and the connecting block 211, and reducing the situation where the connecting rod 3 is separated from the connecting block 211. In addition, the connecting rod 3 is buckled with the connecting block 211. When the connecting rod 3 is subjected to upward or downward force, the connecting block 211 can provide support force for the connecting rod 3, thereby further reducing the situation where the connecting rod 3 is separated from the connecting block 211. The connection between the connecting rod 3 and the connecting block 211 is a detachable connection, which facilitates the operation when one of the heat dissipation components 2 needs to be repaired or replaced.
