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.It is preferred that, 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 is 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 the heat produced by high-power LED lamp chip.And for example, can be integrated with assembling combination when the power of LED chip is smaller Several radiators constitute 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 mouthful 104.For example, each heat conduction Mouthfuls 104 into matrix arrangement.In the present embodiment, the first side wall offers 12 heat conduction mouthful 104, for example, the heat conduction mouthful 104 It is equal to 0.6cm circular open for radius.For example, sandwich chamber is offered on the first side wall of 104 peripheries of heat conduction mouthful, for example, institute The setting of sandwich chamber insertion the first side wall is stated, to lift convection effects；And for example, the sandwich chamber is used to fill thermal conductivity factor higher than aluminium The material of alloy, for example, filling grapheme material, with Local uniqueness conductive performance, so as to realize waveform heat-conducting effect, it is to avoid Heat is excessively concentrated.In the present embodiment, 0.01cm folder is offered on the first side wall in the range of 104 periphery 0.1cm of heat conduction mouthful Layer groove, the sandwich chamber is 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 mouthful 104 and is arranged on the heat conduction When on body 102, sandwich chamber is radiated along the cyclic shape of heat conduction mouthful 104 to the heat carrier 102 away from the heat conduction mouthful 104, it is known that, institute Heat can be rapidly transferred on the heat carrier 102 away from the heat conduction mouthful 104 by stating the packing material in heat conduction mouthful 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 housing 101 is hollow to be set.It should be noted that Hollow setting and frame structure of the invention signified is 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, the housing of hollow setting is adopted With block structure.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, to ensure that heat continuously conducts 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 be played and acted in a balanced way, 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 include 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 Housing 101a and the second housing 101b section are into semi-annular shape, and both are combined into a hollow cylinder.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, improves production efficiency.
