Background technique
High-power illumination equipment is widely used in room lighting, is widely used in the place that height is high, space is big, high-power photograph Illumination, the luminance level of bright equipment are relatively high.But at work due to high-power illumination light fixture, component largely generates heat, pole It is also easy to produce high temperature, the lighting apparatus service life is caused to reduce.And luminous power is bigger, the heat of generation is more, and heat enters room, adds Big air-conditioning system burden.So it is urgently to be resolved for how fast and effeciently radiating while using high-power illumination equipment Problem.In addition to illuminator, there are also some other equipment to be mounted under furred ceiling, and when work also distributes a large amount of heat, for example throws Shadow instrument.If directly can directly take away the heat that illuminator distributes, it is not into room, then these can be greatly reduced The air conditioner load in room, and since the temperature of these equipment is higher, the cooling water of higher temperature can be used, can directly use The cooling water that open water supply or cooling tower generate, this will greatly improve the refrigerating efficiency of refrigeration machine.Heat pipe is twentieth century seven The high-performance heat transfer components that the ten's grew up, heat transfer property with higher.Heat pipe transmits heat, working medium by Working fluid phase changing It absorbs heat and vaporizes in evaporator section, in condensation segment heat release cooling liquid.In thermal energy, refrigeration, building, chemical industry, aerospace, electronics industry Equal fields are widely applied.
The present invention is exactly directed to above-mentioned prior art situation and designs and provide a kind of high power lamps and lanterns cooling ceiling plate, Purpose is to overcome existing large-power lamp cooling side for cooling down common large-power lamp or other high power heat-producing devices The deficiency of formula, improves the cooling effect of lamps and lanterns, and prolonging service lives of lamps reduces room air conditioner load.
The purpose of the present invention is achieved through the following technical solutions:
This kind of heat pipe-type lamps and lanterns cooling device includes ceiling board 1 made of heat-conducting metal, on the top of ceiling board 1 Be laid with and cooling water pipe 2 and be in contact to form heat exchange with ceiling board 1, cooling water pipe 2 be in contact with ceiling board 1 other than part by It keeps the temperature heat insulation layer 3 to wrap up, the both ends of cooling water pipe 2 are respectively water inlet 4, water outlet 5;
Being fixedly connected with one in the lower section of ceiling board 1 can be with the formation heat exchange of ceiling board 1 made of heat-conducting metal Cold plate 6, the lower part of cold plate 6 are fixed evaporation plate 7 made of heat-conducting metal, are existed between cold plate 6 and evaporation plate 7 Gap simultaneously forms a closed space 8, fills heat-pipe working medium in the space 8, the cold plate 6, evaporation plate 7 and is filled in The heat-pipe working medium in space 8 between cold plate 6 and evaporation plate 7 collectively forms flat-plate heat pipe (13) structure;
It is fixedly installed with illuminator 11 in the lower section of evaporation plate 7, the periphery of the lampshade 12 of illuminator 11 connects installation On 1 outer edge of ceiling board.
It is supported between cold plate 6 and evaporation plate 7 being arranged with the support column 9 made of heat-conducting metal in space 8.
There is the fin 10 made of heat-conducting metal in the lower section stationary arrangement of evaporation plate 7 to increase the heat exchange of heat pipe structure Area.
The heat-pipe working medium is with higher gasification latent heat and thermal conductivity, and the lower working medium of viscosity.
Closed space 8 between cold plate 6 and evaporation plate 7 is subnormal ambient.
The heat pipe structure of apparatus of the present invention has, heat exchange efficiency high feature bigger than conventional heat pipe surface area, heat-pipe working medium It is vaporized in closed space 8 from the heat that the absorption illuminator 11 of evaporation plate 7 is distributed at work and rises to upper table Face liquefies in 6 heat release of cold plate, returns 7 position of evaporation plate by gravity, 7 lower surface of evaporation plate is obtained in cycles Heat transfer to 6 upper surface of cold plate.
Apparatus of the present invention the utility model has the advantages that
1. utilizing heat pipe structure and ceiling board, the heat dissipation capacity of lamps and lanterns is directly taken away, air-conditioning system burden can be effectively reduced.And And since the temperature of these heat-producing devices is higher, the cooling water of higher temperature can be used, this will greatly improve the refrigeration of refrigeration machine Efficiency, and it is possible to the cooling water directly generated using natural cold source or cooling tower, air conditioning energy consumption is greatly reduced.
2. can the abundant fast transfer of the quantity of heat production of lamps and lanterns be reduced the operating temperature of lighting apparatus using heat pipe structure, be prolonged The service life of long lighting apparatus.
3. the heat pipe structure takes full advantage of the one-way of gravity assisted heat pipe heat transfer, avoid when cooling water temperature is lower, The condensation trouble that lamp interior is likely to occur improves the safety of this device.
