Automotive headlamp radiator

Abstract

The invention relates to an automotive headlamp radiator capable of effectively improving the radiating effect. The automotive headlamp radiator comprises a base and a heat sink; the base comprises a columnar heat conductor and a disk-shaped bottom plate arranged around the outer side of the heat conductor; a power supply mounting site and a light source groove are respectively formed in the top face and the bottom face of the heat conductor; the heat sink comprises a tubular contact plate and cooling fins vertically, symmetrically and fixedly arranged at the outer side of the contact plate; a gap is formed in one side of the contact plate, and limiting plates are respectively connected with both sides of the gap; the limiting plates are connected through a locating part; an annular slot is formed at the outer side of the power supply mounting site and on the top part of the heat conductor; the inner side of the bottom part of the contact plate is provided with an annular insertion plate; the insertion plate and the slot respectively incline to the direction of the bottom part; an annular baffle is vertically arranged at the inner side of the top part of the contact plate; the inner side face of the contact plate is provided with heat conduction silica gel.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat sink for a vehicle headlamp. Background technique [0002] With the rapid development of the automobile industry, while people are pursuing comfort and ease of handling, more and more attention has been paid to the overall safety, energy saving and environmental protection of automobiles. In this regard, car headlights now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; however, the interior of car headlights is a closed environment, when the car headlights are in the lighting state At this time, the airtight environment where the headlights are located will generate a higher temperature due to heat accumulation. This higher temperature will not only easily generate fog inside the headlights, which will affect the lighting effect, but also easily make the headlights in the car. Parts...

Problems solved by technology

In this regard, car headlights now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; however, the interior of car headlights is a closed environment, when the car headlights are in the lighting state At this time, the airtight environment where the headlights are located will generate a higher temperature due to heat accumulation. This higher temperature will not only easily generate fog inside the headlights, which will affect the lighting effect, but also easily make the headlights in the car. Parts are heated and deformed, and even parts are melted; at present, using a radiator to cool down is a common way of heat dissipation, but the conventional radiator has a poor heat dissipation effect and needs to be improved urgently
