Description

Finned water-filled radiator

Technical field

The utility model relates to a kind of radiator, is specifically related to a kind of water-cooling type radiator.

Background technology

Along with the development of electronics, power technology, particularly along with the increasing substantially of the integrated level of integrated circuit, the heat dissipation problem of electronic devices and components has become one of major issue of the restriction electronic equipment speed of service and power output.

Radiator traditionally all is the fin plate type air-cooled radiator, and it comprises substrate, fin and fan, and fin is uniformly distributed in the one side of substrate, and substrate is levied integral body by the extrusion modling of aluminium alloy one with heat radiation.During use the substrate of this radiator is close on the radiating surface that is installed on electronic components such as chip, is produced a bigger area of dissipation, with fan heat is scattered again, thereby reduce temperature.Though this mode is simple in structure, with low cost, heat dispersion is limited, can only be applicable to the components and parts heat radiation in the electronic equipment that arithmetic speed is not high, power is little.On the other hand, also has a kind of comparatively advanced heat-pipe radiator, it has utilized advanced hot pipe technique, have better radiating effect than traditional fin plate type radiator, still, its production technology is still immature at present, manufacture difficulty big, require high, be subjected to the restriction of material, medium and packaging technology, product is shorter useful life at present, is difficult to large tracts of land and substitutes the universal use of traditional fin plate type air-cooled radiator.

For this reason, people have developed water-filled radiator again on the water-cooled direction in recent years, and it is simple in structure, and because of making heat-conducting medium with water, cooling effect is made fortunately and be convenient, so it is the popular at present feasible program that substitutes traditional fin plate type air-cooled radiator.Be exactly the quad flat housing of a sealing on the existing water-filled radiator structure, establish water inlet and delivery port on the housing, the housing inner chamber is a heat exchanging chamber.During use the one side of this radiator is close on the radiating surface that is installed on electronic components such as chip, water inlet links to each other with water circle device with delivery port, feeds water through water inlet, the delivery port water outlet, and the current heat exchanging chamber of flowing through is taken away heat.When existing water-filled radiator used, just through the feedwater flow of chamber wall conduction all around, heat exchange area was little for heat, and heat exchange coefficient is low, causes exchange capability of heat still not high.

Summary of the invention

The utility model purpose provides a kind of finned water-filled radiator, increases the heat exchange area between heat exchanging chamber and the water, improves heat exchange coefficient, finally strengthens exchange capability of heat.

For achieving the above object, the technical solution adopted in the utility model is: a kind of finned water-filled radiator comprises a seal casinghousing, seal casinghousing is provided with water inlet and delivery port, the seal casinghousing inner chamber is a heat exchanging chamber, is provided with fin in the described heat exchanging chamber, and this fin is arranged along water (flow) direction.

Related content in the technique scheme is explained as follows:

1, in the such scheme, described fin can be covered with whole heat exchanging chamber, but also local distribution as adopts following scheme in heat exchanging chamber: the craspedodrome section place at current is provided with fin, and the turnaround section place of current does not then establish fin.

2, in the such scheme, in order to prolong flow path, can adopt following scheme: a, described heat exchanging chamber between water inlet and delivery port every being provided with a baffle plate, the area of baffle plate constitutes U type water flow passage greater than half of the cross-sectional area of heat exchanging chamber with this; B, described heat exchanging chamber between water inlet and delivery port every being provided with polylith overhead gage and lower baffle plate, these overhead gages and lower baffle plate all replace the parallel interval retaining one by one and are located in the heat exchanging chamber, their area all greater than the cross-sectional area of heat exchanging chamber half, constitutes S type water flow passage with this.

3, in the such scheme, the preferred version of fin setting is: described fin is arranged on current craspedodrome fragment position place in the heat exchanging chamber, the cross section indentation of fin, the top of its sawtooth tooth portion is along fixedlying connected with the upper wall of seal casinghousing, and the end of its sawtooth tooth portion, is along fixedlying connected with the lower wall of seal casinghousing.The concrete structure type of fin that adopts can be following several: a, described fin are straight shape fin, and its surface is the straight slot shape in the longitudinal direction; B, described fin are serrated fin, in the longitudinal direction its surperficial indention curved slot shape; C, described fin are porous shape fin, and its surface is the straight slot shape in the longitudinal direction, and are densely covered with the flow-disturbing hole thereon; D, described fin are corrugated fin, and its surface is corrugated curved slot shape in the longitudinal direction.

4, in the such scheme, described water inlet and delivery port can be located on the upper wall surface or lower wall surface of seal casinghousing, around also can being located on the sidewall.In the time of on being opened in upper wall surface or lower wall surface, another wall is close to installation as the radiating surface of thermal conductive surface and electronic component or chip; On the sidewall time, upper wall surface and lower wall surface all can be used as the radiating surface of thermal conductive surface and electronic component or chip and are close to installation, can be used for semiconductor refrigerating around be opened in.

5, in the such scheme, the shape of described seal casinghousing can be square, circular or the like, generally is flat, and its upper and lower wall area maximum can be used as thermal conductive surface.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because the utility model has increased fin in heat exchanging chamber, heat exchange area increases, and has effectively improved heat exchange efficiency.

2, because the utility model has increased fin in heat exchanging chamber, the design by fin structure also can increase flow-disturbing, and a nearly step has been improved heat exchange efficiency.
