[0003] Modern cars are equipped with car audio systems, and to facilitate the control of audio frequencies and volume, they are usually also equipped with car amplifiers. However, existing car amplifiers have slow heat dissipation, resulting in low cooling efficiency, especially in hot summer weather when the car interior is warm.

[0024] Example

[0025] Please see Figures 1-4 This embodiment provides a high-heat-dissipation vehicle power amplifier, including a housing 1. The bottom of the housing 1 is provided with multiple support feet 9, and a cooling chip, an inner heat sink 8, an outer heat sink 5, a panel 4, etc. are also installed. A ventilation port 14 is installed on the top of the housing 1, and two cooling fans 13 are installed on the ventilation port 14. The heat sink and the cooling fans 13 work together to achieve the heat dissipation effect. In addition, the two cooling fans 13 installed on the top of the housing 1 can perform secondary heat dissipation on the heat that is not completely dissipated from the housing 1 through the ventilation port 14, thereby enhancing the heat dissipation effect of the device.

[0026] The support foot 9 is also equipped with an anti-slip pad 11, which is made of silicone and has strong suction to firmly fix the entire device. The anti-slip pad 11 is fixed with screws 10, which makes it easy to replace at any time.

[0027] The housing 1 has a U-shaped plate structure, and the circuit part of the power amplifier is set in the gap of the housing 1; there are two sets of cooling chips, which are respectively set in the through holes on the left and right walls of the housing 1, with the cold side facing the inside of the housing 1, and the cooling chips are electrically connected to the circuit part; there are two internal heat sinks 8, which are respectively fixed on the left and right side walls of the gap of the housing 1 and are in contact with the cold side of the cooling chips.

[0028] There are two external heat sinks 5, which are fixed on the left and right side walls of the housing 1 respectively and are in contact with the hot side of the cooling plate. The circuit part dissipates heat into the air in the gap of the housing 1. The cold side absorbs heat from the air through the inner heat sink 8, and the hot side absorbs heat from the cold side and dissipates the heat into the outside air through the external heat sink 5.

[0029] A muffler 12 is installed on the top of the cooling fan 13. When the cooling fan 13 is working, it operates synchronously to eliminate noise so as not to damage the sound quality of the car amplifier.

[0030] The cooling fan 13 is also provided with a dust cover 2 of the same size as the housing 1. There is a vent 7 on the top of the dust cover 2, which can facilitate the cooling fan 13 to dissipate heat when it is working. On the one hand, it can prevent the cooling fan 13 from being dusted, and on the other hand, it can protect the cooling fan 13 from wear.

[0031] A rotating shaft 3 is also connected between the dust cover 2 and the housing 1. The dust cover 2 can be opened through the rotating shaft 3 to facilitate cleaning of the cooling fan 13. A handle 15 is also installed on the front side of the dust cover 2 to facilitate opening the dust cover 2 in the future.

[0032] The panel 4 is also equipped with a power switch 16 to control the start and stop of the entire device; there is also a USB interface 17 that can connect multiple devices and charge mobile phones, tablets, etc.; the microphone port 18 can be used to connect an external microphone or car Bluetooth, enabling hands-free calling and improving driving safety and convenience.

[0033] The panel 4 is also equipped with a display screen 19, which can be used to play multimedia content, such as videos, pictures, and animations; the function group 20 includes five function buttons, which are, from left to right, microphone volume adjustment, microphone reverb adjustment, treble adjustment, bass adjustment, and master volume adjustment, thus enhancing the amplifier's flexibility in terms of volume.
