Problems solved by technology

At present, most cars use LED light sources, which will generate a lot of heat during operation. If the heat accumulates inside the car lights and cannot be dissipated in time, it will cause the junction temperature of LED light sources to rise rapidly, which will affect the quality and use of lights. Life expectancy has a serious impact, and it will also affect the driver's line of sight, and there is a great potential safety hazard

Embodiment 1

[0018] The automobile lamp housing of this embodiment includes: a lamp base, a lampshade fastened on the lamp base, and a light source installed on the lamp base, a gasket is provided at the buckle between the lamp base and the lampshade, and the lamp base includes a welded The outer ring and the inner plate of the overall structure, honeycomb holes are formed on the inner plate, and a heat dissipation device is installed on the back of the inner plate. The heat dissipation device includes: a fan and a radiator. There are two heat dissipation fins, and the housing of the fan is formed with installation grooves for accommodating heat dissipation fins, and the depth of the installation grooves is not less than 2cm.

[0019] Among them, the outer ring is made of PP or PET, and the inner plate is made of aluminum plate; the fan is an axial flow fan; the sealant is silicone sealant or ethylene-propylene rubber.

[0020] In this embodiment, the cooling fin is a cylindrical structure...

Embodiment 2

[0022] The structure of the automobile light housing of this embodiment is the same as that of Embodiment 1, the difference lies in the structure of the heat dissipation fins, specifically, in this embodiment, the heat dissipation fins are square tubes with open ends, and the cross-sectional structure of the installation groove is square.

Embodiment 3

[0024] The structure of the automobile lamp housing of this embodiment is the same as that of Embodiment 2, the difference is that: the front and back of the inner plate are all coated with a heat-conducting coating, and the heat-conducting coating includes the following components by weight: water-based ring 15-20 parts of oxygen resin, 8-12 parts of thermal conductive filler, 5-10 parts of inorganic nanoparticles and 10-15 parts of water.

[0025] Wherein, the thermally conductive filler is made by mixing aluminum nitride, glass powder and barium sulfate at a weight ratio of 1:1:1, and the inorganic nanoparticles are nano-titanium dioxide.

Abstract

The invention discloses a high heat dissipation type automobile lamp shell. The high heat dissipation type automobile lamp shell comprises a lamp base, a lampshade buckled to the lamp base and a lightsource installed on the lamp base, a sealing gasket is arranged at the buckling position of the lamp base and the lampshade, honeycomb holes are formed in the lamp base, and a radiating device is installed on the back face of the lamp base; and the radiating device comprises a draught fan and a radiator, the radiator is tightly attached to the back face of the lamp base and is provided with a plurality of radiating fins, and installing grooves for containing the radiating fins are formed in a shell of the draught fan. The high heat dissipation type automobile lamp shell has the beneficial effects that according to the automobile lamp shell, heat generated in the LED light source running process is transferred to the radiating fins of the radiator through the honeycomb holes in an inner plate, then the heat is rapidly discharged through the draught fan, the beneficial effect of being high in radiating is achieved, and the service life of an automobile lamp can be greatly prolonged; andthe inner plate is coated with a heat conduction coating, and therefore the radiating performance of the automobile lamp shell can be further optimized obviously.

Description

technical field [0001] The invention relates to a car lamp shell, in particular to a high heat dissipation type car lamp shell; it belongs to the technical field of auto parts. Background technique [0002] Car lights are the "eyes" of the car and a necessary part for the safe driving of the car. At present, most cars use LED light sources, which will generate a lot of heat during operation. If the heat accumulates inside the car lights and cannot be dissipated in time, it will cause the junction temperature of the LED light source to rise rapidly, which will affect the quality and use of lights. Life expectancy has a serious impact, and it will also affect the driver's line of sight, and there is a great potential safety hazard. In view of this, it is necessary to improve the heat dissipation performance of the automobile lamp housing. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provid...
