Abstract

The invention relates to the technical field of lamps, in particular to a self-exciting type loop heat pipe sunflower heat dissipation module and a large-power LED tube light. The self-exciting type loop heat pipe sunflower heat dissipation module comprises a heat pipe channel internally provided with closed loop type oscillatory flow heat pipes and sunflower fins arranged on the outer wall of the heat pipe channel. Each oscillatory flow heat pipe comprises a working medium with the boiling point ranging from 55 DEG C to 65 DEG C, a heated end tightly attached to a heating component of a product to be cooled and a condensation end away from the heating component of the product to be cooled, wherein the working medium is arranged in a heat pipe cavity. The heat dissipation module is small in size, high in heat conducting efficiency, low in cost and capable of being well applied to LED lights.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a self-excited loop heat pipe solar flower cooling module and a high-power LED downlight. Background technique [0002] LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electrical energy into light energy. However, for larger power LEDs, the heat flux density of the chip is high. When the heat dissipation effect is poor, the temperature of the LED chip will rise sharply, which will quickly cause light decay and even damage the LED chip. Only by solving the heat dissipation technology of high-power LEDs and delaying the light decay of LEDs to the greatest extent can the application of high-power LEDs be widely promoted. [0003] In the market, large-area metals (such as die-casting aluminum ADC12 and 6063-T5 alloy aluminum pro...
