Description
Technical field
The utility model relates to a kind of heat abstractor, especially a kind of replaceable type LED heat abstractor.
Background technology
At present, traditional roads light, its light source adopt powerful mercury vapor lamp, high-pressure mercury lamp or other light sources mostly, and its light source power consumption is big, illuminating effect is not good, maintenance cost is high, and contains hazardous substance mostly in the light source, causes problems such as environmental pollution easily.In recent years, LED lamp development rapidly, luminous efficiency improves greatly, and advantage such as energy-conserving and environment-protective is arranged.Compare with traditional Projecting Lamp electric light source, the basic nonhazardous of led light source, no electromagnetic pollution and volume is little, power consumption is low, light efficiency is high, caloric value is lower and many-sided advantage such as long service life can substitute conventional light source and be widely used in respectively using optical arena.
Great power LED generally adopts led array formula structure, therefore, also can produce a large amount of heat energy when the LED lamp is luminous, will cause the light decay aggravation if imitate the reduction heat, influences the normal use of LED, causes the LED lamp to damage, and reduce service life.How effectively to solve great power LED cooling, become the problem that presses for solution most that the great power LED development is faced.
The radiating and cooling problem becomes in sum influences the difficult problem of great power LED as the bottleneck of lighting field application.Also there are at present some to adopt the lighting of great power LED, but in the solution of heat sink conception, do not reach desirable heat radiation requirement as yet as light source.
Summary of the invention
For solving above-mentioned prior art problems, the utility model provides a kind of replaceable type LED heat abstractor, can form electric heating and separate, and heat radiation fast and safely prolongs LED lamp service life, and can regulate outer fin quantity and density as required.
The scheme that the utility model solves the problems of the technologies described above is: comprise some LED lamps, the LED lamp is by the embedded PCB circuit board front that is installed in of lead, be provided with heat-conducting medium and connect adjacent LED lamp bottom, described heat-conducting medium is concordant with PCB circuit backboard, interior cooling stand is fixed in the PCB back of circuit board, and fully contact with heat-conducting medium, described interior cooling stand longitudinal center position is provided with ventilation slot, cooling stand bottom in some outer fin laterally are assemblied in by interference fit.
For reaching better effect, also be provided with air vent between the above-mentioned two adjacent LEDs lamp, described air vent passes the PCB circuit board and is communicated with ventilation slot.
For reaching better effect, above-mentioned air vent surface is a rectangle.
For reaching better effect, above-mentioned outer fin thickness is 0.5～3 millimeter.
For reaching better effect, above-mentioned ventilation slot is cylindrical.
The utility model can be widely used in the heat radiation of LED lamp, has following advantage compared to existing technology: 1) LED lamp, heat-conducting medium, interior cooling stand, form the integrated radiating structure by the heat conduction between the outer fin, the thermolysis of collocation ventilation slot and air vent can be quick, and safe dispels the heat.2) the utility model is because thermolysis fast, thereby reduced the speed that LED light declines, and prolongs its service life.3) cooling stand bottom in outer fin of the present utility model laterally is assemblied in by interference fit can freely remove and install, in different occasions, and can free adjustment under the situation of different needs.

The specific embodiment
As Fig. 1, the utility model provides a kind of replaceable type LED heat abstractor, and it comprises some LED lamps 4, PCB circuit board 3, heat-conducting medium 2, interior cooling stand 5, outer fin 1.
As Fig. 2, shown in Figure 3, be provided with heat-conducting medium 2 and connect adjacent LED lamp 4 bottoms, and described heat-conducting medium 2 is concordant with PCB circuit board 3 back sides, can well contact with interior cooling stand 5.Interior cooling stand 5 longitudinal center positions are provided with ventilation slot 7, and described ventilation slot 7 is cylindrical.Also be provided with air vent 6 between the two adjacent LEDs lamp 4 and cross PCB circuit board 3 connection ventilation slots 7, described air vent 6 surfaces are rectangle.
Cooling stand 5 bottoms in the utility model China and foreign countries fin 1 laterally is assemblied in by interference fit, its compactness that is evenly distributed.When 4 work of LED lamp, the heat that produces directly is sent to heat-conducting medium 2 by heat exchange pattern, interior cooling stand 5, outer fin 1, thereby distribute heat, forming electric heating in the process separates, ventilation slot 7 has strengthened the area of dissipation of device in addition, and the air ventilation slot 7 of flowing through can be taken away the part heat, quickens heat radiation; Air vent 6 is communicated with ventilation slot 7, and air is flowed through and can further be taken away the heat of heat-conducting medium 2 and interior cooling stand 5.Through such radiator structure, the utility model can be quick, safety, and the LED heat radiation work of finishing of efficient reduces the light decay effect of LED lamp 4, thereby prolongs its service life.
According to actual conditions, the thickness of outer fin 1 can be the 0.5-3 millimeter.Under the situation that device radiation can meet the demands fully, outer fin 1 is partly dismantled, and is attractive in appearance with its arrival, the purpose of reasonable disposition.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong to the scope that the utility model patent contains.
