Problems solved by technology

Although the flat panel LED heat sink with this structure has no restrictions on the installation angle, since each cavity is independent, the heat transfer medium can only circulate in each cavity, and the distance between each cavity and the heat source varies. Similarly, the usage rate of the heat transfer medium in the cavity farther from the heat source is lower, thus resulting in poor heat dissipation uniformity

Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0018] Such as figure 1 combine figure 2 As shown, an LED flat radiator includes a rectangular heat conduction plate 1 and a plurality of heat dissipation fins 2. The heat conduction plate 1 and the heat dissipation fins 2 are integrally extruded from aluminum alloy profiles.

[0019] The surface of the heat dissipation fin 2 is provided with capillary channels 21, which increases the heat dissipation area; the heat dissipation fins 2 are arranged on the top plate 12 of the heat conduction plate 1 at equal intervals along the long side of the heat conduction plate 1, and from the middle to both sides in sequence from high to high. Low arrangement, its role is to set the height of the heat dissipation fins according to the heat of each position, saving profiles.

[0020] A sealed cavity is provided inside the heat conduction plate 1, and the cavi...

Abstract

The invention relates to an LED radiator, belongs to the technical field of radiation and discloses a plated LED radiator. The plated LED radiator comprises a rectangular heat conducting plate and a plurality of radiating fins. A sealed cavity is formed in the heat conducting plate, a plurality of cavity bodies which are communicated with each other are formed in the cavity, a plurality of micro protrusions are arranged at the bottom of the cavity, the cavity is filled by phase change heat transfer media, the radiating fins are arranged on the heat conducting at equal intervals along the long edge of the heat conducting plate, and the heat conducting plate and the radiating fins are formed by integrally extruding aluminum alloy section bars. The cavity bodies in the cavity of the heat conducting plate are communicated with each other, so that when the phase change heat transfer media in the cavity are heated to boil, vapor can be filled into all parts of the cavity to enable temperatures of all points of a bottom plate to trend to be the same. All radiating fins can effectively work to improve radiating evenness. The hollow bottom plate reduces the weight of the plated LED radiator. Meanwhile, the plated LED radiator has no limit on installation angles.

Description

technical field [0001] The invention relates to heat sink technology, in particular to an LED flat heat sink. Background technique [0002] At present, there are two common types of LED radiators: sunflower-shaped LED radiators and flat-plate LED radiators. The sunflower-shaped LED radiator adopts gravity heat pipe technology, which has good heat dissipation performance, but has certain restrictions on the installation angle. The flat-plate LED heat sink consists of a hollow bottom plate and a number of heat dissipation fins. The hollow bottom plate is divided into several independent cavities, and a heat transfer medium is arranged in the cavity. Although the flat panel LED heat sink with this structure has no restrictions on the installation angle, since each cavity is independent, the heat transfer medium can only circulate in each cavity, and the distance between each cavity and the heat source varies. Similarly, the usage rate of the heat transfer medium in the cavity...
