Abstract
The present invention relates to a manufacture method of radiator. Said manufacture method includes the following steps: fixing welding flux layer on the zone of radiating fin into which the heat pipe can be inserted and setting welding aid layer between external surface of welding flux layer and external surface of heat pipe; inserting the heat pipe into fixing hole of radiating fin; and heating the combination of the heat pipe and radiator.
Description
[technical field]
The present invention relates to a kind of manufacturing method of heat radiator, the particularly a kind of manufacturing method of heat radiator that can between heat pipe and fin, realize evenly, firmly weld.
[background technology]
As shown in Figure 1, in known assembly type radiator, perforation 11 is set on fin 10 and recess 111 is set at perforation 11 inner ring, and along the profile of perforation 11 and recess 111 around flange 12 is arranged.Utilize recess 111 to irritate the casting space, make scolder enter gap between flange 12 and the heat pipe 20, with increase weld strength and heat conduction efficiency through recess 111 as scolder.But in scolder is flowed through the process that 111 pairs of flanges of recess 12 and heat pipe 20 weld, because the flowability problem and the heat pipe 20 of scolder may contact with flange 12 parts, may cause heat pipe 20 and heat pipe 20 and flange 12 welding uneven problem inconsistent with the weld strength between the different fin.
In the industry cycle also the someone attempt by at heat pipe coating surface scolder again at scaling powders such as scolder outer surface coating rosin, heat pipe is inserted in the fixing hole of fin, opposite heat tube and fin combination is subsequently heated, and is fixing to realize welding.But because scaling powder is coated in the outer surface of scolder, be inserted in the process of fixing hole of fin,, had a strong impact on welding effect because the friction between heat pipe and the fixing hole edge makes scaling powder come off from the outer surface of scolder at heat pipe.
[summary of the invention]
For the scaling powder on heat pipe surface in the manufacture method that solves prior art comes off in the process of inserting the fin fixing hole easily, can't realize technical problem even, that firmly weld, the invention provides a kind of manufacturing method of heat radiator that can between heat pipe and fin, realize evenly, firmly weld.
The scaling powder that the present invention solves heat pipe surface in the manufacture method of prior art comes off in the process of inserting the fin fixing hole easily, can't realize evenly, the technical scheme that technical problem adopted of firmly welding is: a kind of manufacturing method of heat radiator is provided, and this manufacture method comprises: a. will insert on the zone of radiator fixing solder layer and between the surface of the outer surface of solder layer and heat pipe the scaling powder layer is set at heat pipe; B. heat pipe is inserted the fixing hole of fin; C. heat the combination of heat pipe and radiator.
According to one preferred embodiment of the present invention, step a comprises: be pressed on the heat pipe at the inner surface coating scaling powder layer of single layer welding flitch material and with single layer welding flitch material volume.
According to one preferred embodiment of the present invention, step a comprises: clamping scaling powder layer and double-deck scolder sheet material volume is pressed on the heat pipe between double-deck scolder sheet material.
According to one preferred embodiment of the present invention, step a comprises: be pressed on the described heat pipe at coating scaling powder layer on the heat pipe and with the welded blank volume.
According to one preferred embodiment of the present invention, step a also comprises: by welding method scolder sheet material is fixed on the heat pipe.
According to one preferred embodiment of the present invention, scolder sheet material is sheet tin.
According to one preferred embodiment of the present invention, scaling powder is a rosin.
According to one preferred embodiment of the present invention, step c comprises: the combined heated of heat pipe and radiator is arrived predetermined temperature, heat pipe is welded on the fin.
By adopting said structure, prevented to insert in the process of fin fixing hole by utilizing solder layer parcel scaling powder at heat pipe because the technical problem that friction comes off scaling powder, thus guaranteed between heat pipe and the radiator evenly, firmly welding.

[specific embodiment]
The present invention is described in detail below in conjunction with drawings and Examples.
As Fig. 2-shown in Figure 4, Fig. 2 is the structural representation of heat pipe used in the present invention, and Fig. 3 is that Fig. 3 is the cut-away section enlarged diagram of heat pipe shown in Figure 2, and Fig. 4 is the structural representation of heat pipe and fin combination among the present invention.In manufacturing method of heat radiator of the present invention, at first need to insert on the zone of fin 32 fixedly solder layer 33, and between solder layer 33 and heat pipe 31, be provided with scaling powder layer 35 at heat pipe 31.Wherein, solder layer 33 and scaling powder layer 35 are made by the following method: for example, the single layer welding flitch material of at first making appropriate size (for example, sheet tin) and on the surface of scolder sheet material (for example apply scaling powder, rosin), the scolder sheet material volume that will scribble scaling powder then is pressed on the heat pipe 31, utilizes flatiron to form some solder joints 37 subsequently on scolder sheet material, by solder joint 37 scolder sheet material is fixed on the heat pipe 31.Then, the heat pipe 31 that is fixed with solder layer 33 is inserted in the fixing hole of fin 32, and the combination of opposite heat tube 31 and fin 32 is subsequently heated, and makes solder layer 33 fusings, so that heat pipe 31 is welded on the fin 32,32 one-tenth structures as shown in Figure 4 of heat pipe 31 and fin shape.By said method, between heat pipe 31 and solder layer 33, when heat pipe 31 was inserted in the fixing hole of fin, scaling powder layer 35 can not come off because of the friction between heat pipe 31 and the fin 32 like this with scaling powder layer 35 double team.Utilize the burn into humidification of scaling powder layer 35 to make heat pipe 31 be welded to fin 32 securely subsequently, and because solder layer 33 surround heat pipe 31, the even distribution of the scolder after the fusing between the fixing hole of heat pipe 31 and fin 32.
The heat pipe that can also have in addition, solder layer by other method preparation.For example, by using double-deck scolder sheet material and between double-deck welded plate, applying scaling powder, be pressed in double-deck scolder sheet material volume on the heat pipe subsequently and weld.Perhaps at heat pipe surface applied scaling powder, be pressed in scolder sheet material volume on the heat pipe subsequently and weld fixing.
In the above-described embodiments, only the present invention has been carried out exemplary description, but those skilled in the art can conspicuously expect the scaling powder layer being arranged between the outer surface and heat pipe surface of solder layer by other method or structure reading present patent application, with prevent the scaling powder layer in heat pipe is inserted into the process of radiator fixing hole, come off and guarantees solder fusing after evenly distribution.In addition, also can expect utilizing other suitable scolders and scaling powder to replace above institute's tin of mentioning and rosin.
