Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to a heat dissipation duct component for automobile lamps. Background Art

[0002] The headlight cooling duct is an air circulation channel designed for headlight heat dissipation. It aims to remove the heat generated by the headlight during operation through air flow to ensure the normal operating temperature of the headlight and extend the service life of the headlight. Most existing headlight cooling ducts are curved and narrow, which increases the resistance to air flow, reduces the air circulation speed, and prevents heat from being removed in time, affecting the use of the headlight.

[0003] Therefore, it is necessary to provide a new heat dissipation duct assembly for vehicle lights to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a heat dissipation duct assembly for a vehicle lamp.

[0005] The heat dissipation duct assembly for vehicle lights provided by the utility model includes: a first duct, which is a rectangular structure, and is fixedly connected to a second duct at the rear right side of the first duct, and the connection between the two is well sealed to ensure that airflow does not leak, and a heat dissipation plate shell is fixedly connected to the right side of the first duct, and the air inlet inside the first duct is fixedly connected to a first motor through a first fixing plate, and the first motor drive is fixedly connected to a first rotating shaft, and the other end of the first rotating shaft is fixedly connected to a small fan, and the blades of the small fan are designed to be arc-shaped to reduce noise.

[0006] Preferably, a second motor is fixedly connected to the right side of the second air duct through a second fixed plate, a second rotating shaft is fixedly connected to the drive of the second motor, and a large fan is fixedly connected to the other end of the second rotating shaft. The setting of the small fan in the first air duct forms a contrast, and together constitute the fan drive system of the entire air duct assembly to achieve more efficient heat dissipation airflow circulation.

[0007] Preferably, a first heat dissipation fan blade is provided in the middle of the heat dissipation plate housing, and a second heat dissipation fan blade is provided on both sides of the heat dissipation plate housing. The first heat dissipation fan blade and the second heat dissipation fan blades on both sides increase the heat dissipation area.

[0008] Preferably, a second air outlet is provided on the right side of the second air duct to guide the direction of the airflow, so that the discharged airflow is smoother and the generation of vortices is reduced.

[0009] Preferably, a first air outlet is provided on the right side of the top of the first air duct. Since the density of hot air is smaller than that of cold air, part of the hot air floats to the first air outlet for preliminary heat dissipation.

[0010] Preferably, a lamp driving board is fixedly connected to the left side of the heat sink housing, and the two are glued together by thermal conductive adhesive to ensure that the heat generated by the lamp driving board can be efficiently transferred to the heat sink housing.

[0011] Preferably, a filter plate is fixedly connected to the air inlet of the first air duct, which can effectively filter out dust, impurities and other particulate matter.

[0012] Compared with the related art, the heat dissipation duct assembly for vehicle lights provided by the present invention has the following beneficial effects:

[0013] The utility model provides a heat dissipation duct assembly for a vehicle lamp. The heat dissipation area is increased by installing a first air duct, a second air duct and a heat dissipation plate, and a first heat dissipation fan blade in the middle of the heat dissipation plate shell and a second heat dissipation fan blade on both sides. In addition, since the air volume of the small fan is smaller than that of the large fan, a negative pressure is formed inside the heat dissipation duct assembly. Driven by the negative pressure, the air flow will flow through the heat dissipation fan blades in a more directionally oriented manner, so that the fan blades can disturb the air flow more efficiently and enhance the heat dissipation effect.

[0021] See also Figures 1 to 4 The embodiment of the present invention provides a heat dissipation duct assembly for a headlight, which includes: a first duct 1, which is a rectangular parallelepiped structure. The right rear side of the first duct 1 is fixedly connected to the second duct 2. The connection between the two is well sealed to ensure that the airflow does not leak. The right side of the first duct 1 is fixedly connected to a heat dissipation plate housing 7.

The other end of the first rotating shaft 10 is fixed. A small fan 11 is connected, and the blades of the small fan 11 are designed to be arc-shaped to reduce noise. A second motor 12 is fixedly connected to the right side of the second air duct 2 through a second fixing plate 13. The second motor 12 is fixedly connected to a second rotating shaft 14 at the moving end. A large fan 15 is fixedly connected to the other end of the second rotating shaft 14. A first cooling fan blade 16 is provided in the middle of the heat sink housing 7. Second cooling fan blades 17 are provided on both sides of the heat sink housing 7. A second air outlet 6 is provided on the right side of the second air duct 2 to guide the direction of the airflow and make the discharged airflow more The heat dissipation effect is improved by adjusting the heat dissipation coefficient of the heat dissipation fan 11 and the heat dissipation fan 12. The heat dissipation effect is improved by adjusting the heat dissipation coefficient of the heat dissipation fan 11 and the heat dissipation fan 12. The heat dissipation effect is improved by adjusting the heat dissipation coefficient of the heat dissipation fan 11. The heat dissipation effect is improved by adjusting the heat dissipation coefficient of the heat dissipation fan 11 and the heat dissipation fan 12.

[0023] The working principle of the heat dissipation duct assembly for vehicle lights provided by the utility model is as follows: the lamp driving board 3 generates heat during operation. Due to the good thermal conductivity of the thermal conductive adhesive, the heat can be efficiently transferred from the lamp driving board 3 to the heat dissipation plate housing 7. At this time, the air blowing toward the heat dissipation plate housing 7 will take away the heat. Moreover, the first heat dissipation fan blades 16 arranged in the middle of the heat dissipation plate housing 7 and the second heat dissipation fan blades 17 on both sides increase the heat dissipation area. Moreover, since the air volume of the small fan 11 is smaller than that of the large fan 15, a negative pressure is formed inside the heat dissipation duct assembly. Driven by the negative pressure, the airflow will flow through the heat dissipation fan blades in a more directionally manner, so that the fan blades can disturb the airflow more efficiently and enhance the heat dissipation effect.
