Grille type led radiator

Abstract

The invention relates to a grid type LED (Light Emitting Diode) radiator, which is capable of effectively increasing the heat conduction efficiency and the heat dissipation efficiency. The grid type LED radiator comprises a radiator main body, wherein the radiator main body comprises a back plate and side plates which are vertically arranged at the edges of the back plate, and a heat dissipation chamber is formed by the side plates in a surrounding way; a containing chamber is formed in the heat dissipation chamber through heat conduction plates in the surrounding way, a separating plate is arranged in the containing chamber, and the containing chamber is divided into a power supply groove and a light source groove by the separating plate; the heat dissipation chamber is internally provided with grids which are used for connecting the side plates with the head conduction plates, flow guiding air pipes are arranged between the grids in a penetrating way, vent holes are formed in the back plate, and one end of each flow guiding air pipe is connected with the corresponding vent hole.

Description

technical field [0001] The invention relates to a heat sink for automobile lamps, in particular to a grid-type LED heat sink. 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 the automobile. In this regard, in order to reduce the energy consumption of automobile lighting, the existing technology Car headlights usually use LED lights and adopt planar cluster packaging technology to 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, the headlights The closed environment where the lamp is located will generate a higher temperature due to heat accumulation, which will not only easily generate fog inside the headlight and affect the lighting effect, but also...

[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 the automobile. In this regard, in order to reduce the energy consumption of automobile lighting, the existing technology Car headlights usually use LED lights and adopt planar cluster packaging technology to 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, the headlights The closed environment where the lamp is located will generate a higher temperature due to heat accumulation, which will not only easily generate fog inside the headlight and affect the lighting effect, but also easily cause the parts in the car headlight, especially the plastic parts, to be deformed by heat. There is even a phenomenon of melting; at present, using a radiator to cool down is a common heat dissipation method. In order to improve the heat dissipation efficiency, the radiator is usually set in a grid shape. However, in this way, due to the airflow between the radiator fins Without circulation, there is still the problem of low heat dissipation efficiency
