A kind of heat pipe lampshade that can derive the light source heat rapidly
Technical field:
The present invention relates to a kind of heat pipe lampshade that can derive the light source heat rapidly, belong to the device of subduing the light source fuel factor in the artificial environment facility, the heat that light source can be sent is delivered to outside the system rapidly.Be used for greenhouse, phjytotron, plant factor, illumination box etc.
Background technology:
Along with the development of modern agricultural technology, artificial environment facilities such as increasing greenhouse, phjytotron, plant factor, illumination box come into operation.For satisfying the illumination condition requirement, use the kinds of artificial light source, or even high-power artificial light source.These artificial light sources also produce a large amount of heat energy when satisfying intensity of illumination.These heat energy are unnecessary as a rule, need eliminate these heats with artificial refrigeration plant, to reach the desired temperature conditions of artificial environment.And the power consumption of these artificial cooling equipment has significantly improved the operating cost of artificial environment facility, even the artificial environment facility occurs because of big " with not rising " the caused idle phenomenon of power consumption when environment temperature is higher.
Summary of the invention:
For overcoming above-mentioned deficiency of the prior art or drawback, the invention provides a kind of heat pipe lampshade that can derive the light source heat rapidly, according to heat pipe principle, utilize the vapour of working media, liquid phase to become heat transfer, the heat that light source is sent is delivered to outside the system rapidly.
For achieving the above object, the present invention takes following technical scheme: a kind of heat pipe lampshade that can derive the light source heat rapidly is made of heat absorption lampshade, heat pipe tube connector and radiator.The heat absorption lampshade comprises heat-protecting glass, reflection shield, endothermic tube and thermal insulation layer, reflection shield is that good heat conducting material is made, endothermic tube is close to reflection shield, the endothermic tube structure can be spiral coil, cage shape tubulation or comb teeth pipe, be the heat absorbing end (evaporimeter) of heat pipe, heat absorption lampshade socket place cover is with heat-protecting glass; To the absorb heat endothermic tube of lampshade of heat pipe tube connector is connected with outdoor radiator, can be that two ends have the bite type joint, be connected with outdoor radiator with endothermic tube respectively with the bite type joint, also can be directly with two ends and endothermic tube and outdoor radiator welding, heat pipe tube connector pipe with thermal insulation layer, is the adiabatic section of heat pipe outward; Radiator is installed in outdoor, is helix tube or calandria structure, is the radiating end (condenser) of heat pipe, and radiating mode can be water-cooled or the forced convertion formula that has fan, also can be the free convection formula; Be filled with the low boiling working media in the heat pipe, the boiling point of working media is at 20 ℃~100 ℃, and preferably between 30 ℃~60 ℃, heat pipe is interior through extracting the air rear enclosed.The present invention can arrange by single lamp absolute construction, also can arrange by many lamps parallel-connection structure.
The present invention is directed in the prior art some deficiency or drawback and design, its beneficial effect is, according to heat pipe principle, utilize the vapour of working media, liquid phase to become heat transfer, the heat that light source is sent is delivered to outside the system rapidly, the device thermal resistance is very little, the capacity of heat transmission is strong, consumes energy extremely low even need not power, can effectively reduce the fuel factor of light source, significantly subdue the cooling load of artificial environment facility, reduce operating cost.
