Detailed description of the invention
In order to describe technical scheme in detail, below in conjunction with the accompanying drawing of the embodiment of the present invention, the technical scheme of the embodiment of the present invention is carried out clear, complete description.Obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under the premise without creative work, broadly fall into the scope of protection of the invention.
Refer to Fig. 1～8, the radiator of the present invention includes: multiple fin 1, and fin 1 is respectively provided with the endothermic section 11 being arranged in tandem with each other and the radiating part 12 extended from endothermic section 11；For extruding and fixing the bindiny mechanism of the laminated construction of endothermic section 11.
Wherein, the flange 13 that the side of each fin 1 is provided with punching press through hole and is formed, wherein the radiating part 12 of each fin 1 expands radially in the extrusion process of bindiny mechanism under the effect of flange 13.Due to after punching press, the external diameter of flange 13 can more than the internal diameter of through hole, so, in extrusion process, the flange 13 of later fin 1 will not snap in the through hole of previous fin 1, it is the flange 13 of the later fin 1 through hole side that props up previous fin 1 on the contrary, plays tilting effect, make the radiating part 12 of each fin 1 expand radially.The benefit of this way is, while manufacturing fin 1, can form flange 13 by punching press through hole, simple and convenient, and, it is not necessary to snapping, as long as directly extruding, it is possible to the radiating part 12 realizing each fin 1 expands radially, efficient and convenient.
Wherein, the both sides, top (i.e. inner edge and outside) of the radiating part 12 of each fin 1 all form the engaging portion 14 protruding from radiating part 12 side.In the present embodiment, the engaging portion 14 of fin 1 is formed for extending from the both sides, top of radiating part 12 and bending inwards 90 degree.Further, the engaging portion 14 of each fin 1 forms the insertion hole 142 of insertion section 141 traverse of the abutting fins 1 of insertion section 141 and permission fin 1 side.In the present embodiment, the insertion section 141 of fin 1 is formed for extending from the end of engaging portion 14 and bending inwards 90 degree.Further,；The end of the insertion section 141 of the outside at the top of the radiating part 12 of each fin 1 also forms the back-off hole 144 that the back-off portion 143 of the abutting fins 1 of back-off portion 143 and permission fin 1 side buckles into.Namely the insertion section 141 of radiating part 12 inner edge is not provided with back-off portion 143 and back-off hole 144, and the insertion section 141 outside radiating part 12 is distinctive in that: end also forms the back-off hole 144 that the back-off portion 143 of the abutting fins 1 of back-off portion 143 and permission fin 1 side buckles into.In the present embodiment, the back-off portion 143 of fin 1 is formed for extending from the end of the insertion section 141 of outside and bending inwards 90 degree.The upper end of engaging portion 14 of each fin 1, lower end all inwardly form spacing block 145.In the present embodiment, the spacing block 145 of fin 1 is formed for extending from the top and bottom of engaging portion 14 and bending inwards 90 degree.By above-mentioned fastening structure, the insertion section 141 making later fin 1 can through the insertion hole 142 of previous fin 1, then, the back-off portion 143 of this later fin 1 can buckle into the back-off hole 144 of previous fin 1, so that the radiating part 12 of two fin 1 links closely, even if in the processes such as assembling, transport, installation, it also is difficult to depart from, and this fastening structure, also ensure that the distance between the radiating part 12 of each fin 1 is constant, its distance is the width of engaging portion 14.
In the present embodiment, it is preferable that the through hole stamped out of fin 1 is circular hole, and flange 13 is formed at the periphery of through hole side, so, facilitates punching press.Wherein, bottom the radiating part 12 of fin 1, equal symmetrical molding has 2 flanges 13 so that the radiating part 12 on fin 1 both sides all can launch preferably.
Wherein, bindiny mechanism includes crushing block 2 and connector, endothermic section 11 and be provided with the fixing hole 15 allowing connector to pass through on crushing block 2, in order to make the radial expansion under the effect of flange 13 of each radiating part 12 in extrusion process.In the present embodiment, bindiny mechanism includes the crushing block 2 being separately positioned on the laminated construction both sides of endothermic section 11, crushing block 2 and endothermic section 11 are provided with fixing hole 15, and connector can be screw bolt and nut etc., make bolt penetrate crushing block 2 and endothermic section 11 fixing hole 15 and and nut screw connection, to realize the fixing of the laminated construction to endothermic section 11.
The manufacture method of the present invention is: first, stamps out fin 1 and each position, hole, and while punching press fin 1, forms flange 13 by punching press through hole；Then, engaging portion 14, insertion section 141, back-off portion 143 are bent out at the radiating part 12 of fin 1；Then, two fin 1 are stacked, and make the insertion hole 142 through previous fin 1, the insertion section 141 of later fin 1, and the back-off portion 143 of later fin 1 buckles into the back-off hole 144 of previous fin 1, so that the radiating part 12 of two fin 1 links closely, repeat this step, to form the laminated construction of the fin 1 of predetermined quantity；Then, extrude and fix the laminated construction of endothermic section 11, make the radiating part 12 of fin 1 expand radially under the effect of flange 13.
As can be seen from the above scheme, the flange 13 that the present invention is formed not only by punching press through hole, make the radiating part 12 of fin 1 expand radially under the effect of flange 13 in the extrusion process of bindiny mechanism, keep radiating effect；And, the present invention utilizes insertion section 141 through the insertion hole 142 of the abutting fins 1 of side, and back-off portion 143 is buckled into the back-off hole 144 of the abutting fins 1 of side, make to link closely and keep at a distance between the radiating part 12 of each fin 1 constant, the problem avoiding existing fin 1 easily to cause the spacing of radiating part 12 to diminish, even stick together because of deformation, makes radiating effect better.
Finally should be noted that; above example is only in order to illustrate technical scheme; but not limiting the scope of the invention; although having made to explain to the present invention with reference to preferred embodiment; it will be understood by those within the art that; technical scheme is modified or equivalent replacement, all belong to protection scope of the present invention.
