Abstract
The invention relates to the field of illumination equipment design, in particular to a heat radiation system of a high-power LED lamp. The heat radiation system comprises a heat radiator body and a light-emitting source, wherein the light-emitting source is mounted at the bottom of the heat radiator body; heat radiating fins vertical to the top surface of the heat radiator body are also mounted on the top surface of the heat radiator body; a vacuum cavity is formed in the heat radiator body; an energy-carrying working medium is arranged in the vacuum cavity; and an infrared heat radiation layer is also arranged on the outer surface of each heat radiating fin. According to the heat radiation system, the vacuum cavity is formed in the heat radiator body and heat is transferred by the energy-carrying working medium, so that the heat exchange efficiency and the heat radiation effect are improved; the heat radiating fins are arranged on the top surface of the heat radiator body, so that the area of contact between the heat radiation system and air is greatly increased and the efficiency of heat radiation by air convection is improved; and the infrared heat radiation layer is arranged on the outer surface of each heat radiating fin, so that the heat radiation system is higher in heat radiation efficiency and heat radiation speed.
Description
Technical field
The present invention relates to the lighting apparatus design field, relate in particular to a kind of high-power LED lamp cooling system.
Background technology
Carry the medium that energy working medium refers to can absorb or emit because state parameter own changes energy, namely medium is carrier of energy.
Existing lighting apparatus uses the metal mold radiator more, and mainly be divided into two kinds according to conductive structure: first metal heat-conducting, another kind are heat pipe for thermal conductivity.
The metal heat-conducting structure comprises heater, substrate, heat-conducting silicone grease colloid, metal heat sink.Its heat radiation process is: the heat of heater is transmitted to metal heat sink by substrate, heat-conducting silicone grease colloid, and the heat that is transmitted on the metal heat sink dispels the heat by cross-ventilated mode.But the shortcoming of metal heat-conducting structure is clearly, when teaching big lighting apparatus for power, because the restriction of the physical property of heat-conducting silicone grease colloid own causes the integral heat sink inefficiency, can not meet the demands, even the problem that can cause lighting apparatus to damage.
The heat pipe for thermal conductivity structure comprises heater, heat pipe, metal heat sink.Its heat radiation process is: the heat of heater is transmitted to metal heat sink by heat pipe, and the heat that is transmitted on the metal heat sink dispels the heat by cross-ventilated mode.But pass to heat to the heat exchanging process of metal heat sink at heat pipe, heat conduction efficiency is difficult to control, and radiating efficiency also is very low during actual the use.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of high-power LED lamp cooling system.
In order to realize the foregoing invention purpose, technical scheme of the present invention is:
A kind of high-power LED lamp cooling system comprises radiator body, light emitting source; Described light emitting source is installed in the bottom of radiator body; At the end face of described radiator body fin perpendicular to the radiator body end face is installed also; Radiator body inside has vacuum cavity, is provided with in vacuum cavity inside to carry energy working medium.
Alternatively, the outer surface at described fin also is provided with the infrared emanation layer.
Alternatively, the number of described fin is 10.
Alternatively, described year energy working medium is water.
The present invention is by arranging vacuum cavity in radiator body inside, improved rate of heat exchange of the present invention, carry and working medium to conduct heat by in vacuum cavity, charging into, improve heat exchanger effectiveness, improve radiating effect, by at the radiator body end face fin being set, significantly increased the area that the present invention contacts with air, improved the efficient of cross-ventilation heat radiation.
The present invention also arranges the infrared emanation layer by the outer surface at fin, makes radiating efficiency of the present invention higher, and radiating rate is faster.
