In order to improve the radiating efficiency of radiator, for example, the housing 101 uses frame structure.The housing of frame structure 101 can increase its own contact area with air, improve the convection current of housing 101 and air.Preferably, the housing 101 It is made up of aluminum alloy materials.In other embodiment, can be selected according to actual application environment the higher metal of thermal conductivity factor or Metal alloy, it is for instance possible to use albronze, and for example, can use fine copper metal.Thermal source heat is taken away to increase housing 101 The efficiency of amount, also, can accelerate the radiating efficiency of whole radiator on the basis of the raising of cross-ventilation speed.

For the ease of by each radiator assembling combination, in one embodiment, the housing 101 of frame structure is into cylinder Shape, i.e. it is cylindrical shape.For example, a height of 2-10cm of housing 101, bottom surface radius 1-5cm.In one embodiment, shell A height of 5cm of body 101, bottom surface radius are 2cm.The volume of the housing 101 can confirm final according to needs of production Produce size.For example, when needing heat sink applications in high-power LED lamp chip, the volume of the housing 101 needs to fit With heat caused by high-power LED lamp chip.And for example, when the power of LED chip is smaller, can be integrated with assembling combination Several radiators form a relatively large LED.

In order to further improve the radiating efficiency of radiator, for example, the housing 101 includes the first side wall and two vertical The connection wall of the first side wall, the connection wall of two vertical the first side walls is arranged at the both ends of the first side wall, to cause the first side Wall and two connection walls are combined into cylinder.For example, a height of 3cm of the first side wall, two connection wall radiuses are 1cm.The first side wall It is made with two connection walls of aluminium alloy.The first side wall offers some heat conduction mouths 104.For example, each heat conduction Mouthfuls 104 into matrix arrangement.In the present embodiment, the first side wall offers 12 heat conduction mouths 104, for example, the heat conduction mouth 104 It is equal to 0.6cm circular open for radius.For example, sandwich chamber is offered on the first side wall of the periphery of heat conduction mouth 104, for example, institute State sandwich chamber insertion the first side wall to set, to lift convection effects；And for example, the sandwich chamber is higher than aluminium for filling thermal conductivity factor The material of alloy, for example, filling grapheme material, in Local uniqueness conductive performance, so as to realize waveform heat-conducting effect, to avoid Heat is excessively concentrated.In the present embodiment, 0.01cm folder is offered on the first side wall in the range of the periphery 0.1cm of heat conduction mouth 104 Layer groove, the sandwich chamber are filled with grapheme material.For example, the sandwich chamber is additionally provided with a thin film aluminum alloy, the thin film aluminum Alloy is used to seal the sandwich chamber.In this way, the heat-conducting part 103 is corresponding with the heat conduction mouth 104 and is arranged on the heat conduction When on body 102, sandwich chamber radiates along 104 cyclic shape of heat conduction mouth to the heat carrier 102 away from the heat conduction mouth 104, it is known that, institute Heat can be rapidly transferred on the heat carrier 102 away from the heat conduction mouth 104 by stating the packing material on heat conduction mouth 104, from And quickly realize the radiating on heat-conducting part 103.

In order to further improve the radiating efficiency of radiator, and for example, the 101 hollow setting of housing.It should be noted that Signified hollow setting of the invention and frame structure are two kinds of approximate constructions.For example, the thickness of the housing of hollow setting is more than frame The thickness of the housing of frame structure setting, that is to say, that the housing of frame structure uses the structure of tabular, and the housing of hollow setting is adopted With the structure of bulk.For example, the hollow space of the housing 101 is used to place heat carrier 102.The heat carrier 102 with it is described Housing 101 is brought into close contact.It is appreciated that it is in order to avoid heat is conducted through between housing 101 and heat carrier 102 to be brought into close contact It is interrupted in journey, causes heat to be assembled in housing 101, reduces radiating efficiency.In order to realize the mode being brought into close contact, for example, The heat carrier 102 is connected with the housing 101 by the way of interference fit.And for example, the heat carrier 102 and the housing 101 connect by the way of gap coordinates.For example, gap coordinate after between the heat carrier 102 and the housing 101 between Gap fills heat conductive silica gel.And for example, graphite is filled in the gap after coordinating in gap between the heat carrier 102 and the housing 101 Powder, continuously conducted with ensureing heat between housing 101 and heat carrier 102.For example, heat carrier 102 uses heat conduction with housing 101 The different material of coefficient is made, for example, heat carrier 102 is made up of graphite material.And for example, heat carrier 102 runs through whole housing 101, to cause heat carrier 102 that heat is rapidly transferred to the various pieces of housing 101.Due to the thermal conductivity factor of heat carrier 102 More than housing 101, when heat is gathered in a certain region on housing 101, heat carrier 102 can play the effect of equilibrium, by this The heat in region is rapidly transferred to the region of housing 101.In this way, the radiating efficiency of radiator can be improved.

For the ease of by the installation settings of heat carrier 102 in the housing 101, as shown in Fig. 2 for example, the shell Body 101 includes the first housing 101a and the second housing 101b, the heat carrier 102 be arranged at the first housing 101a with it is described Between second housing 101b.That is, the first housing 101a symmetrically offers the first groove to hold with the second housing 101b Heat carrier 102 is put, and heat carrier 102 is clamped between the first housing 101a and the second housing 101b.In the present embodiment, first Into semi-annular shape, both are combined into a hollow cylinder in housing 101a and the second housing 101b section.The heat carrier 102 For cylinder, its external diameter is equal to the first housing of semi-annular shape 101a internal diameter, with cause the housing 101a of heat carrier 102 and first and Second housing 101b is brought into close contact.In this way, the housing 101a of heat carrier 102 and first and the second housing 101b peace can be simplified Dress, improve production efficiency.

In order to further improve the radiating efficiency of radiator, with reference to Fig. 2 and Fig. 3, for example, the heat carrier 102 is in described Being extended at heat conduction mouth 104 has heat conduction projection 104a, and the heat-conducting part 103 offers storage tank 103a, the heat conduction projection 104a wears the heat conduction mouth 104 and is contained in the storage tank 103a.For example, the heat conduction projection 104a is graphite material system Into its heat-conducting system is higher than housing 101.For example, the heat conduction projection 104a is integrally formed with the heat carrier 102.It is described to lead Hot projection 104a distribution matches the heat conduction mouth 104, that is to say, that the position of the heat conduction projection 104a is determined at when described After heat carrier 102 is arranged in the housing 101, determine that the heat conduction is convex according to the position distribution of the heat conduction mouth 104 Positions of the block 104a with respect to heat carrier 102.For example, heat conduction projection 104a, which is arranged in the heat conduction mouth 104, protrudes from housing 101, To cause heat conduction projection 104a to be partially housed in the storage tank 103a away from housing 101, also, heat conduction projection 104a is remote The part of housing 101 fully contacts with the storage tank 103a.For example, heat conduction projection 104a and the sandwich chamber opening connect Touch.For example, heat conduction projection 104a is brought into close contact with the sandwich chamber and contacted with packing material.For example, the heat-conducting part 103 is used In mounted LED lamp component.For example, the heat-conducting part 103 is provided with installation position, the installation position is backwards to the storage tank 103a. LED lamp component is installed on the installation position.In this way, it can make it that a heat part passes through heat-conducting part 103 caused by LED lamp component Conduction is conducted to heat carrier 102 to heat conduction projection 104a and by heat conduction projection 104a.Because the heat of LED lamp component is mainly assembled In the region of the storage tank 103a backwards, therefore heat conduction projection 104a rapidly can conduct the heat of the aggregation to heat conduction Body 102.Also, because packing materials of the heat conduction projection 104a also with the sandwich chamber contacts, the heat of the aggregation can also pass The packing material is directed at, and is conducted by packing material to housing 101, so, the heat of LED lamp component can be quickly by leading Hot projection 104a and packing material are conducted to housing 101, so as to prevent LED chip because temperature is too high and hydraulic performance decline, improve The quality of product, also, improve the radiating efficiency of radiator.

For the ease of the heat-conducting part 103 is arranged on housing 101, for example, housing 101 was in the heat conduction mouth 104 weeks Edge, which is provided with, plugs together position, and heat-conducting part 103 is provided with the portion of plugging together backwards to the side of the installation position, plugs together position and fastens company with the portion of plugging together Connect.For example, plug together position protrudes from heat-conducting part 103 along the heat conduction mouth 104 into annular shape, the portion of plugging together.For example, described plug together Portion is circlewise raised along heat-conducting part 103, and described plug together offers toroidal cavity among portion, and the circular position that plugs together houses In the toroidal cavity.It is appreciated that plugging together after position and the portion of plugging together be fastened and connected, heat-conducting part 103 can revolve with respect to housing 101 Turn.In this way, the heat-conducting part 103 is fastened and connected by plugging together position with the portion of plugging together, can be easily by the heat-conducting part 103 On housing 101, and it is possible to suitably adjust the position of heat-conducting part 103 by rotating heat conducting portion 103.

In order to keep the electrical connection of wire on heat-conducting part 103 and housing 101, for example, the position that plugs together is provided with some the One conducting strip.For example, it is described plug together position and plug together the side in portion described in offer some first paster grooves, a conduction Piece is placed in the first paster groove.For example, a surface that plugs together is provided with three the first conducting strips, three first are led Electric piece is respectively first positive grade of conducting strip, the first cathode conductive film and the first ground connection conducting strip.For example, the portion of plugging together is provided with Some second conducting strips.For example, it is described plug together portion and plug together the side of position described in offer some second paster grooves, an institute State the second conducting strip and be placed in the second paster groove.The portion of plugging together is provided with three the second conducting strips, three second Conducting strip is respectively second positive grade of conducting strip, the second cathode conductive film and the second ground connection conducting strip.Inserted with described the position that plugs together After conjunction portion is fastened and connected, first conducting strip is abutted and electrically connected with second conducting strip.Preferably, the first positive level is conductive Piece, the first cathode conductive film and the first ground connection conducting strip sequence interval spread configuration, second positive grade of conducting strip, the second negative conductive Piece and the second ground connection conducting strip sequence interval spread configuration.For example, the position that plugs together is set in first positive grade of conducting strip near zone The first flag bit is equipped with, the portion that plugs together is provided with the second flag bit with second positive grade of conducting strip near zone, for example, described Portion is plugged together with being provided with the second flag bit by second positive grade of conducting strip, so that the proper position that plugs together fastens company with the portion of plugging together Pass through appropriate rotation after connecing to adjust so that the first flag bit and the second flag bit overlap, with cause first positive grade of conducting strip with Second positive grade of conducting strip is fully abutted and electrically connected, first negative grade of conducting strip is fully abutted and be electrically connected with second negative grade of conducting strip Connect, the first ground connection conducting strip is fully abutted and electrically connected with the second ground connection conducting strip.In this way, heat-conducting part 103 and shell can make it that Wire on body 101 keeps electrical connection.
