Description
Technical field
The utility model relates to a kind of lighting device, relates in particular to a kind of liquid-cooling LED lamp.
Background technology
Existing LED illumination reaches just uses more and more widely as the product of light-emitting component, but the heating when work of LED element is serious, therefore must add cooling device; Cooling device commonly used at present adopts the air cooling more, comprises two kinds of schemes of active heat removal and passive heat radiation; Active heat removal; Be used in low-power device, when power reaches 400W or when above, equipment all will improve the material and the area requirements of heat radiation greatly more; Influenced the Weight control of product, radiating effect is not good simultaneously; Passive heat radiation mainly adopts radiator to add the radiating mode of ventilation unit, and this mode can further improve radiating effect on the basis of active heat removal, reduces material and the area requirements of equipment to heat radiation simultaneously.
Plant is in growth course, and light has played sizable effect, and natural daylight action time is constant; As there not being artificial increase illumination in the time of natural daylight, then can shorten original production cycle of plant greatly, further improve plant products; And the artificial light sources power that is used to increase plant illumination is bigger; Must use passive heat radiation, but this lamp source need be used in wet environment, and the light source of passive heat radiation can't pass through sealed damp-proof; Therefore not long service life as the fan of ventilation unit, reliability is low.
The utility model content
The utility model is for solving the prior art problem, and a kind of good heat dissipation effect, liquid-cooling LED lamp that reliability is high are provided.
The technical scheme of the utility model is: a kind of liquid-cooling LED lamp; Comprise light source portion and the cooling device that is arranged at light source portion one side; Said cooling device comprises the heat-transfer device of being close to said light source portion, and the heat transfer unit (HTU) that is connected with said heat-transfer device, and the heat abstractor that is connected with said heat transfer unit (HTU); Said heat transfer unit (HTU) is connected said heat-transfer device and heat abstractor, and forms the heat conduction circulation of a sealing; Be provided with heat-exchange tube in the said heat-transfer device, the refrigerant in this heat-exchange tube is a liquid.
The heat energy that light source produces is delivered to the heat-transfer device of being close to through conduction, at heat-transfer device set inside heat-exchange tube, through liquid flow the heat energy that light source produces is taken away, and is delivered to heat abstractor through heat transfer unit (HTU); The radiating effect of this radiating mode is better than common wind-cooling heat dissipating, and the heat dissipating package device is used for the occasion of plant growth, not influenced by aqueous vapor, and security reliability is high.
As preferably, said cooling device also is provided with liquid reserve tank, and this liquid reserve tank is series in the said heat conduction circulation.
As preferably, be tightly connected through snap joint between said heat-transfer device, heat transfer unit (HTU) and the heat abstractor.The snap joint good seal performance, and can not carry out dismounting by instrument, easy to use.
As preferably, also be provided with temperature inductor in the said heat-transfer device.
As preferably, also be provided with the volume control device of control circulation rate in the said heat conduction circulation.
Data through temperature inductor provides are adjusted the cold medium flux that flows in the heat abstractor, and when light-source temperature was higher, enlargement discharge when light-source temperature is not high, reduced flow to cut down the consumption of energy to quicken heat radiation.
As preferably, a said heat abstractor is connected with an above heat-transfer device.
In sum, the utlity model has following advantage:
1, the cooling effect of liquid cooling is higher than the air-cooled cooling effect of tradition, effectively reduces the temperature of led light source node, prolongs light source service life;
2, no fan design does not receive the influence of moisture in the environment, adapts to wide;
3, a cover heat abstractor can dispel the heat to many covers light source, and use cost is low.
