Embodiment Construction

[0017] A radiative heat dissipation cooling coating, including A component, B component and filler, A component is the main coating, which is a solution formed by agglomeration of modified colloid particles treated at high temperature, and the particle size of the modified colloid particles is less than 100 nanometers, B component is ethylenediamine curing agent, the weight ratio of A component / B component is 9:1, and the filler is a material with high thermal conductivity and infrared emission, such as carbon nanotube or spinel Stone metal oxides.

[0018] The preparation method of the radiation cooling coating of the present invention is obtained by adding fillers to component A and mixing them uniformly, then slowly adding component B to component A, stirring slowly mechanically, and standing for 30 minutes. use.

[0019] The above-mentioned radiation cooling coating can be applied to LED lamps to improve the LED cooling effect in the form of infrared radiation. The specif...

Abstract

The invention discloses a radiative heat loss cooling coating which comprises a component A, a component B and a filler, wherein the component A is a main coating, and is a solution prepared by condensing modified colloidal particles treated at a high temperature, the component B is an ethidene diamine curing agent, the weight ratio of the component A to the component B is 9:1, and the filler is a material which is high in heat conductivity and has an infrared emitting property. The radiative heat loss cooling coating disclosed by the invention can be applied to an LED (Light Emitting Diode) lamp, automatically radiates heat into an atmosphere space or a lamp body at an emitting rate of about 0.9 epsilon and an infrared wavelength band of 0.5-13.5 mu m so as to accelerate heat exchange and reducing temperatures of the surface and the interior of an LED lamp body, thereby driving the reduction of a work junction temperature of an LED chip.

Description

technical field [0001] The invention relates to the application field of thermal radiation technology, in particular to a radiation cooling coating, its preparation method and its application. Background technique [0002] Since the advent of LED (light-emitting semiconductor) white light technology, it has triggered the fourth revolution in human lighting. From indoors to outdoors, LEDs are widely used in the field of lighting. In particular, the future development potential of high-power street lamps is greater, because it has an energy-saving effect of more than 50% compared with the current "dominant" high-pressure sodium lamps, and the current power consumption of urban road lighting in my country accounts for about 13% of my country's total power generation. Therefore, the promotion and popularization of LED street lamps gradually replace high-pressure sodium lamps, and its macroscopic energy-saving significance is very significant. In recent years, the luminous flux o...
