Description

Technical Field

[0001] The utility model belongs to the technical field of capacitors, and in particular relates to a car audio capacitor with enhanced heat dissipation. Background Art

[0002] Capacitors, often referred to simply as capacitance for their ability to hold charge, are devices that hold charge. Capacitors, as the name suggests, are a type of electronic component used extensively in electronic devices, and are widely used in circuits for DC isolation, AC flow, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. Any two insulated, closely spaced conductors form a capacitor.

[0003] After searching, a Chinese utility model patent (authorization announcement number: CN215731328U) provides a car audio capacitor, including a capacitor body, a heat sink, a mounting seat, a shock-absorbing fixing component, a first display screen, a second display screen, a temperature sensor and a control host. A heat sink is installed on the surface of the capacitor body, the front and rear ends of the capacitor body are fixedly connected to the mounting seat, the bottom of the mounting seat is fixedly connected to the shock-absorbing fixing component, the capacitor body includes a contact head, the top of the contact head is installed with a first display screen and a second display screen, the temperature sensor and the control host are both installed inside the capacitor body, and the first display screen, the second display screen and the temperature sensor are all electrically connected to the control host.

[0004] A cooling fan is installed on the capacitor body, an air outlet of the cooling fan faces the heat sink, and the cooling fan is electrically connected to the control host.

[0005] In the above-mentioned prior art, the heat sink is used to dissipate heat from the capacitor body, and the temperature sensor is used to monitor the temperature of the capacitor body and transmit the monitored data to the control host. When the temperature reaches the set threshold, the control host controls the cooling fan to work. The cooling fan dissipates heat by blowing air to the heat sink, thereby accelerating the heat dissipation of the capacitor body. The above-mentioned prior art has strong heat dissipation capacity.

[0006] However, in the above-mentioned prior art, the cooling fan can only accelerate the heat dissipation on one side of the heat sink, resulting in uneven heat dissipation. The heat dissipation effect of the heat sink on the capacitor is slower where the cooling fan is not installed. Therefore, the above-mentioned shortcomings need to be improved urgently. Summary of the Invention

[0009] Preferably, a bracket is provided on the outer peripheral wall of the heat dissipation tube, and a heat dissipation fan is installed on the bracket.

[0010] Preferably, a transparent cover is installed at the end of the capacitor, a snap ring is provided on the transparent cover, a limiting ring and an abutting ring are provided on the heat dissipation tube, a ring groove is formed between the limiting ring and the abutting ring, and the snap ring is limitedly fitted in the ring groove.

[0013] Preferably, a rubber pad for shock absorption is provided at the bottom of the fixing seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The utility model provides a car audio capacitor with enhanced heat dissipation, which can achieve better air circulation effect through convection holes on the heat dissipation tube and ventilation holes on the heat dissipation fins, thereby improving the heat dissipation effect of the capacitor. In addition, a heat dissipation fan is further used to blow air into the convection holes, thereby accelerating the flow of air, so that the heat dissipation effect is further improved.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, a car audio capacitor with enhanced heat dissipation includes a capacitor 1 and a heat dissipation component 2 installed on the capacitor 1. The heat dissipation component 2 includes a heat dissipation tube 21 and a plurality of heat dissipation fins 24. The heat dissipation tube 21 has a receiving cavity for the capacitor 1. The heat dissipation fins 24 are evenly arranged on the inner wall of the receiving cavity. The other end of the heat dissipation fin 24 contacts the capacitor 1, thereby playing a heat conduction role, so that the heat of the capacitor 1 is conducted through the heat dissipation fin 24 to achieve heat dissipation. The heat dissipation tube 21 is provided with a plurality of evenly distributed convection holes 22. A dustproof net 221 is provided in each of 22 to prevent dust from entering the accommodating cavity, thereby avoiding the occurrence of poor heat dissipation caused by dust accumulation in the accommodating cavity. A number of evenly distributed vents 25 are provided on the heat sink 24. The vents 25 make the interior of the accommodating cavity interconnected, and the accommodating cavity is connected to the atmosphere through the convection holes 22 on the heat sink 21. Therefore, air circulates with the atmosphere through the convection holes 22 on the heat sink and the vents 25 on the heat sink 24, thereby improving the heat dissipation effect of the capacitor 1 by enhancing air circulation.

[0025] The tail of the heat dissipation tube 21 is snap-fitted with a dust cover 29 , and the dust cover is provided with a plurality of snap-fit ​​blocks 291 . The tail of the heat dissipation tube 21 is provided with a plurality of snap-fit ​​holes 211 snap-fitted with the snap-fit ​​blocks 291 .

[0026] A bracket 23 is provided on the outer peripheral wall of the heat dissipation tube 21 , and a heat dissipation fan 3 is installed on the bracket 23 . The heat dissipation fan 3 blows air into the convection holes 22 , thereby accelerating the flow of air and further improving the heat dissipation effect.

[0027] A transparent cover 11 is installed at the end of the capacitor 1, and a snap ring 12 is provided on the transparent cover 11. A limiting ring 26 and an abutting ring 27 are provided on the heat dissipation tube 21. A ring groove 28 is formed between the limiting ring 26 and the abutting ring 27. The snap ring 12 is limited and fitted in the ring groove 28. The limiting ring 26 and the abutting ring 27 cooperate with the snap ring 12 to limit the movement of the heat dissipation tube 21 in the axial direction.

[0028] When the clamping ring 12 is located in the annular groove 28 , the end surface of the limiting ring 26 away from the clamping ring 12 is an inclined surface, so that the heat dissipation tube 21 is installed more smoothly.

[0029] In addition, a fixing base 4 is included, which has an installation cavity 41. The heat dissipation tube 21 is installed in the installation cavity 41. A rubber pad 5 for shock absorption is provided at the bottom of the fixing base 4. A rubber ring 42 is provided on the inner wall of the installation cavity 41. By installing the capacitor 1 into the installation cavity 41, the capacitor 1 squeezes the rubber ring 42 to deform the rubber ring 42, thereby increasing the friction between the capacitor 1 and the rubber ring 42, so that the capacitor 1 is installed more stably.
