Abstract

The utility model belongs to radiating fin head technical field, a kind of more particularly to radiating fin head with infiltration seam, two thermal vias that the radiating fin head body bottom is formed connect fin respectively, the thermal vias two side ends form two symmetrical steps respectively, the infiltration seam for two-sided welding is formed among radiating fin head body and fin through docking, the utility model solves prior art and radiating fin head be present with fin due to being single-sided welding, the problem of causing poor welding quality and easily breaking, with making welding bead evenly full, once weld, double-faced forming, prevent from breaking, it ensure that the advantageous effects of the quality of welding.

Description

A kind of radiating fin head with infiltration seam

Technical field

The utility model belongs to radiating fin head technical field, more particularly to a kind of radiating fin head with infiltration seam.

Background technology

The terminal device of Home Heating, thermal source are generally city central heating, the self-built boiler room of cell, Domestic wall stove Deng heat spreader is come out by heat transfer, radiation, convection current, allows the temperature in room to get a promotion, steel radiator, aluminum dissipate Hot device, copper radiator, stainless steel heat radiator, composite copper aluminium radiator, steel combined with aluminum radiator etc., also original cast iron dissipate There is radiating fin head with fin due to being single-sided welding in hot device, prior art, what is caused poor welding quality and easily break asks Topic.

Utility model content

The problem of the utility model provides a kind of radiating fin head with infiltration seam, and prior art is present is that prior art is deposited In radiating fin head and fin due to being single-sided welding, the problem of causing poor welding quality and easily break.

The technical problem that the utility model solves is realized using following technical scheme：A kind of radiating with infiltration seam Head, including radiating fin head body, two thermal vias that the radiating fin head body bottom is formed connect fin respectively, institute State thermal vias two side ends and form two symmetrical steps respectively, formed and used among radiating fin head body and fin through docking Stitched in the infiltration of two-sided welding.

Further, the solder of the radiating fin head body outer surface permeates surface in the inner through infiltration seam.

Further, the weld bond between the radiating fin head body and fin is inside and outside has two-sided solder.

Further, the infiltration seam is in bar shaped.

Advantageous effects：

1st, two thermal vias that this patent is formed using the radiating fin head body bottom connect fin respectively, described Thermal vias two side ends form two symmetrical steps respectively, are formed and are used among radiating fin head body and fin through docking The infiltration seam of two-sided welding, the solder of the radiating fin head body outer surface permeate surface in the inner, the radiating through infiltration seam Weld bond between head body and fin is inside and outside to have two-sided solder, due to when fin and radiating fin head dock, due to The step of thermal vias withstands fin so that permeates seam together with being formed in fin and radiating fin head, the head take infiltration Joint stabilizing process, increase infiltration seam is in order that welding bead is evenly full, once welds, double-faced forming, prevents from breaking, ensure that welding Quality.

Brief description of the drawings

Fig. 1 is a kind of structural representation for the radiating fin head that there is infiltration to stitch of the utility model；

Fig. 2 is a kind of structural representation for the radiating fin head body that there is infiltration to stitch of the utility model.

Embodiment

The utility model is described further below in conjunction with accompanying drawing：

In figure：1- radiating fin head bodies, 2- thermal vias, 3- fin, 4- steps, 5- infiltration seams.

Embodiment：

The present embodiment：As shown in figure 1, a kind of radiating fin head with infiltration seam, including radiating fin head body 1, it is described to dissipate Two thermal vias 2 that the bottom of backing head body 1 is formed connect fin 3 respectively, and the two side ends of thermal vias 2 are formed respectively Two symmetrical steps 4, the radiating fin head body 1 through docking stitch 5 with being formed among fin 3 for the infiltration of two-sided welding.

The solder of the outer surface of radiating fin head body 1 permeates surface in the inner through infiltration seam 5.

There is two-sided solder inside and outside weld bond between the radiating fin head body 1 and fin 3.

The infiltration seam 5 is in bar shaped.

Operation principle：

Two thermal vias that this patent is formed by the radiating fin head body bottom connect fin respectively, described to dissipate Heat through-hole two side ends form two symmetrical steps respectively, are formed among radiating fin head body and fin through docking for double The infiltration seam of face welding, the solder of the radiating fin head body outer surface permeate surface in the inner, the fin through infiltration seam Weld bond between head body and fin is inside and outside to have two-sided solder, due in fin and radiating fin head docking, due to scattered The step of heat through-hole withstands fin so that seam is permeated together with being formed in fin and radiating fin head, the head take infiltration to stitch Technique, the utility model solve prior art and radiating fin head be present with fin due to being single-sided welding, cause welding quality Difference and the problem of easily break, having makes welding bead evenly full, once welds, double-faced forming, prevents from breaking, ensure that welding Quality advantageous effects.

Using the technical solution of the utility model, or those skilled in the art is in the inspiration of technical solutions of the utility model Under, similar technical scheme is designed, and reach above-mentioned technique effect, it is to fall into the scope of protection of the utility model.
