[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model is described in detail.

Referring to Fig. 1-Fig. 4, in radiator 1 of the present utility model, fin 11 comprises superimposed 112 and the

heat radiation fin

111 and 113 that is arranged on superimposed 112 both sides.Wherein, be respectively arranged with through hole 114,115 on the heat radiation fin 111 and 113.Also be provided with fixed via on superimposed 112.Crushing block 13, bolt 14 and nut 15 cooperate with fixed via with superimposed 112 superimposed and pinched together, form the endothermic section of radiator 1 thus.

Fin

111 and 113 are from the radial expansion in this endothermic section in heat radiation, form the radiating part of radiator 1 thus.Certainly, can be by riveted, bonding or other suitable connector or connection means with superimposed on superimposed 112 and be secured together.In the present embodiment, the radiating segment 121 of heat pipe 12 is located in the through hole 114,115 of heat radiation fin 111 and 113,122 of the endotherm sections of heat pipe 12 are arranged in the groove of endothermic section of radiator 1, realize thus the hot link between endothermic section and the

heat radiation fin

111 and 113.

In the present embodiment, for the ease of manufacturing, each fin 11 is made by same specification, makes that at

heat radiation fin

111 and 113 from the endothermic section after the radial expansion, radiating part has elliptic cross-section.121 cambers of the radiating segment of heat pipe 12 are arranged in the through hole 114,115 of the fin 111,113 that respectively dispels the heat.But those skilled in the art can design multiple difform fin according to actual needs, so that make the radiator shape after the assembling be fit to specific application.At this moment the through hole 114,115 that for example replaces

heat radiation fin

111 and 113 with the recess of appropriate format only needs the radiating segment 121 of heat pipe 12 is set directly in the recess, can realize the hot link of endothermic section and

heat radiation fin

111 and 113 of radiator 1.

In the present embodiment, the groove of the endothermic section of radiator 1 is combined by the pre-recess on above-mentioned superimposed 112 and crushing block 13.According to a kind of optimal way, after the endotherm section 122 of heat pipe 12 is arranged in the groove, make endotherm section 122 omit the heat-absorbent surface outstanding and endothermic section, make endotherm section 122 extruding be fixed on groove inside by fashion of extrusion subsequently, increase integrally-built fastness thus.In addition, the effect of pushing also is to make the heat-absorbent surface of compressive plane endothermic section of endotherm section 122 of heat pipe 12 equal substantially, make endotherm section 122 direct parts as the endothermic section, so that when being assembled into radiator 1 on the pyrotoxin surface, the compressive plane of endotherm section 122 contacts with the pyrotoxin surface, further improves heat-transfer effect.In addition, the plane also can be made in advance in the side of this endotherm section 122, and the shape of pre-designed groove and the degree of depth, so that the endotherm section 112 of heat pipe 12 is equal substantially with the heat-absorbent surface of endothermic section by the side that this groove exposes after assembling, improves heat-transfer effect thus.

The above, it only is preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every application the utility model specification and accompanying drawing content are done, direct or letter scoops out and is used in other relevant technical field, all in like manner is included in the claim of this utility model.
