Embodiment 1

[0036] like figure 1 shown.

[0037] A method for improving the heat dissipation efficiency of LED lighting sources based on heat pipe technology. The key is to install the LED chip substrate in the substrate groove of a horizontally placed integrated heat pipe radiator, so that the heat generated by the LED light source can be transferred to the heat pipe for heat dissipation through heat conduction. The evaporation end of the cylindrical direct heat pipe 2 perpendicular to the base plate of the device makes the working medium in the cylindrical direct heat pipe 2 absorb heat to produce a liquid-vapor phase transition, and the generated steam diffuses to the entire cylindrical direct heat pipe under the action of the pressure difference inside the heat pipe The tube body, so as to exchange heat with the surrounding environment through the tube wall and the heat dissipation fins 3 on the tube wall, the steam condenses into small droplets and then adheres to the tube wall liqui...

Abstract

The invention discloses a method for improving the heat radiating efficiency of an LED lighting source and an integrated radiator. The method comprises the steps as follows: an LED chip substrate is mounted in a substrate groove of a heat pipe radiator, so that heat produced by the LED lighting source is conducted to an evaporation end of a cylindrical straight heat pipe in the radiator, a working medium in the heat pipe absorbs the heat and produces liquid-vapor phase transition, produced vapor is spread to a whole heat pipe body under the action of differential pressure inside the heat pipe, and further the vapor exchanges heat with a surrounding environment through the heat pipe wall and radiating fins on the pipe wall; and the vapor is attached to the inside of a liquid suction core of the pipe wall after condensed into droplets and flows back to the evaporation end of the heat pipe under the action of the differential pressure inside the wick, so that circulatory heat radiation is realized. The radiator comprises a heat pipe radiator substrate (1), the cylindrical straight heat pipe (2), the radiating fins (3), a heat pipe end cover (4), the webby wick (5) and a rubber gasket. The radiator is simple in structure and good in radiating effect.

Description

technical field [0001] The present invention relates to a heat dissipation technology, in particular to a heat dissipation technology for LED lighting sources, specifically a method for improving the heat dissipation efficiency of LED lighting sources based on heat pipe technology and an integrated chemical radiator. Background technique [0002] At present, with the rapid development and wide application of LED lighting sources, a high-power LED lighting source array integrated with multiple LED chips has gradually appeared. The traditional fin heat sink can no longer meet the heat dissipation performance requirements of high-power LED lighting sources. The heat dissipation problem of LED lighting sources has become a key issue that limits the actual life of LED lighting sources. In order to fully utilize the advantages of energy saving, environmental protection, and long life of LED lighting sources, it is urgent to effectively solve the problem of heat dissipation. [00...
