Abstract

The invention discloses a heat pipe radiator for high-power LED lamps. The heat pipe is a U-shaped heat pipe, and the heat load installation platform is welded to the bend of the heat pipe. Arranged on the heat pipe, the heat sink is located in the two guard arms of the guard plate; the invention provides a U-shaped gap matching the heat pipe structure on the heat load mounting platform, and sets a circle matching the diameter of the heat pipe on the heat sink and the guard plate. Holes make it fully connected to the heat pipe, the thickness of the heat sink is only between 0.3-1mm, which can effectively transfer the heat of the heat pipe to the heat sink, and the heat dissipation efficiency is high; the guard plate is made of a thick aluminum plate with a thickness of 1.5-2.5mm or Compared with ordinary radiators, the weight is greatly reduced, and the anti-vibration and impact resistance are good; the surface area of ​​the overall structure is more than five times that of ordinary radiators, and the weight is only one-fifth of ordinary radiators.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a heat pipe radiator for high-power LED lamps. Background technique [0002] Since the luminous intensity and service life of LED are greatly affected by the working temperature, the higher the working temperature, the lower the luminous intensity and service life. Therefore, in general, when the power of LED exceeds 1.5W, it is necessary to consider designing a heat dissipation structure to reduce the working temperature of the LED. , the most commonly used method in the industry is to add a metal radiator behind the LED soldered circuit board. The metal radiator is generally made of aluminum alloy or copper alloy. The general process for making this type of radiator is profile stretching, or mold casting. [0003] However, the heat sink with profile stretching is used for process limitations, and one profile needs to be used up every time. The blanking cost in the early stag...
