Description
Technical field
The embodiment of the utility model is related to laser television field of radiating, more specifically, the embodiment party of the utility model
Formula is related to a kind of efficient radiating apparatus applied to laser television.
Background technology
At work, laser can generate a large amount of heat for the DLP laser televisions of laser light source, and the aggregation of heat causes
Laser television generates heat deterioration, seriously reduces the image quality of projected image, while can reduce the service life of laser.Mesh
High brightness is emphasized in preceding laser television on the market mostly, once brightness improves, the heat of generation is naturally more, along with laser
Device core component is the design of clad type, and internal body space is smaller, therefore heat dissipation design is laser TV system design
One of key factor.
The radiating mode of current laser television is forced mainly by the use of metal (aluminium or copper) as radiator by fan
Convection current is radiated, but there is heat dissipation effect is bad, the installation drawbacks such as fan is bulky.
Existing heat sink conception, is specifically shown in Fig. 1, and radiator includes finned radiator 2 and heat pipe 1, finned radiator 2
Including multi-disc fin.Fin is welded on a surface of radiating bottom plate, and the another of radiating bottom plate is welded at heat pipe one end 11
On surface, by being welded together to form radiating bottom plate, fin, heat pipe with overall structure, radiating efficiency can be effectively improved,
But for the DLP projector of laser light source, the power of laser is larger and heat source is concentrated, which can not be timely and effective
Distribute laser generation heat, cause radiating efficiency of the prior art relatively low.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of embodiment, it is expected to solve at present
Core component laser is designed using clad type, and internal body space is small, and caused heat dissipation design difficulty is big, influences perspective view
The image quality of picture, the problems such as reducing the service life of laser.
To solve the technical issues of above-mentioned, a kind of embodiment of the utility model uses following technical scheme：One kind should
For the efficient radiating apparatus of laser television, including heat-radiating substrate and groups of fins, the groups of fins is arranged on heat-radiating substrate
Top surface on, cavity is set in the heat-radiating substrate, the cavity is separated into several cavitys by several partition boards, is equipped in the cavity
Coolant, the evaporating temperature of coolant is 40-60 DEG C.
Further technical solution is：The groups of fins includes multiple cooling fins, and the cooling fin is disposed on
The top surface of heat-radiating substrate.
Compared with prior art, one of the beneficial effects of the utility model are：Originally be utility model provide be applied to swash
The efficient radiating apparatus that photoelectricity regards, radiator therein is by multiple groups of fins being disposed on the top surface of heat-radiating substrate
Into being provided with cavity in heat-radiating substrate, equipped with coolant in cavity, the evaporating temperature of coolant is 40-60 DEG C.When coolant by
When temperature is increased to evaporating temperature, coolant becomes the top that gas rises to the cavity, and gas transfers heat to described
Heat-radiating substrate top surface, the top surface of heat-radiating substrate transfers heat to cooling fin, at this point, the temperature of gas is reduced to evaporation temperature
Become liquid below degree and fall back to cavity bottom, the heat-transfer effect of radiator can be greatly improved in cycles.Pass through the base that radiates
Coolant circulating transfer heat in plate, makes heat more rapidly transfer heat to cooling fin from laser light source, improves radiator
Heat-transfer effect, reduce the temperature difference between laser light source and radiator, the radiating efficiency of laser projection greatly improved.
Description of the drawings
Fig. 1 is the structure diagram of prior art radiator.
Fig. 2 is the structure diagram of the utility model radiator.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this practicality
It is novel, it is not used to limit the utility model.
Embodiment
With reference to figure 2, a kind of efficient radiating apparatus applied to laser television comprising heat-radiating substrate 1 and groups of fins 2, swashs
Light device and installing plate are fixed at heat-radiating substrate 1, and the heat that laser generates is transmitted to groups of fins 2 by heat-radiating substrate 1,
Groups of fins 2 includes multiple cooling fins being disposed on the top surface of heat-radiating substrate 1, and cavity, the chamber are set in heat-radiating substrate 1
Body is separated into several cavitys 3 by several partition boards 4, coolant 5 is housed, the evaporating temperature of coolant 5 is 40-60 in the cavity 3
DEG C, when coolant heating temperature is increased to evaporating temperature, coolant becomes the top that gas rises to cavity 3, and gas transmits
Heat is to the top surface of heat-radiating substrate 1, and the top surface of heat-radiating substrate 1, which transfers heat to, spreads backing, at this point, gas temperature is reduced to steaming
Become liquid below hair temperature and fall back to 3 bottom of cavity, in cycles.During work, recycled by the coolant in heat-radiating substrate 1
Heat is transmitted, heat is made more quickly to transfer heat to cooling fin from laser heat source, improves the heat-transfer effect of radiator, is reduced
The temperature difference of laser and radiator, realizes high efficiency and heat radiation.
Although reference be made herein to the utility model is described in the explanatory embodiment of the utility model, however, it should
