Abstract

The utility model relates to a radiator structure having increased heat radiating area, particularly a radiator structure which can cause the spacing among heat radiating fins to obtain higher density and better heat radiating effect, which comprises an integral forming mould, wherein, an integral forming radiator can be formed from the mould, a pedestal is formed at the bottom part of the radiator, a plurality of heat radiating fins are formed on the pedestal, and a plurality of flow passages and gaps are arranged among the radiating fins; because the flow passages and the gaps are designed, the heat radiating fins of the radiator have higher density spacing and better heat radiating effect, and the radiator can exert larger heat radiating capability; the strength of the mould can be effectively increased, the mould which is deformed is avoided, and the utility model can be suitable for producing in large quantities.

Description

Has the heat spreader structures that increases area of dissipation

Technical field

The utility model relates to a kind of heat spreader structures that increases area of dissipation that has, especially refer to that a kind of spacing that makes radiating fin obtains the heat spreader structures of higher density and preferable radiating effect, and can make the bigger heat-sinking capability of radiator performance, and can effectively increase the intensity of mould, avoid mould to deform, more can be fit to mass-produced heat spreader structures.

Background technology

Progress along with science and technology, the computer execution speed is more and more fast, but it is also more and more higher with respect to the temperature that is produced in the main frame, for the temperature that will be produced in the main frame is dispersed into outside the system effectively, work under the situation of allowable temperature with each assembly of keeping in the main frame, usually to be attached on each assembly surface that produces temperature to have the larger area radiator, increase its radiating effect by this radiator.

See also Figure 1 and Figure 2, be to be the die casting of existing radiator or male model (as Fig. 1) structure of jetting mold 10, form the groove 11 that several is a fixed range and is provided with at interval on this mould 10, this mould 10 also can form integrated radiator 12 (as Fig. 2), these radiator 12 bottoms are in order to form a base 121, form several radiating fin 122 on this base 121, be provided with several runner 123 between this radiating fin 122 and the radiating fin 122, this runner 123 can help this radiating fin 122 to dispel the heat rapidly, link a radiator fan (figure slightly) on this radiator 12, and temperature on this radiator 12 is reduced and discharge by the radiator fan of running, increase its radiating effect.

Because better heat radiating effect must have the radiating fin 122 of higher density, and above-mentioned mould 10 is owing to be subject to mechanical process capacity and manufacture method, more groove 11 can't be set, cause the radiating fin that forms 122 excessive at interval, its density, spacing are all not satisfactory, thereby reduce its radiating effect, and can't bring into play bigger heat-sinking capability.

As from the foregoing, the mould structure of above-mentioned existing radiator in actual installation or use, obviously has many places inconvenience and shortcoming, and can wait to be improved.

Based on this, inventor of the present utility model is at above-mentioned shortcoming, is that the spy concentrates on studies and cooperates actual utilization, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned shortcoming finally.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of heat spreader structures that increases area of dissipation that has, can make the spacing of radiating fin obtain the heat spreader structures of higher density and preferable radiating effect, and get so that the bigger heat-sinking capability of radiator performance, can effectively increase the intensity of mould, avoid mould to deform, more can be suitable for a large amount of productions.

For achieving the above object, the utility model provides a kind of heat spreader structures that increases area of dissipation that has, especially refer to that a kind of spacing that makes radiating fin obtains the heat spreader structures of higher density and preferable radiating effect, it comprises integrated mould, this mould also can form integrated radiator, one base is formed on this radiator bottom, forms several radiating fin on this base, is provided with several runner and gap between this radiating fin and the radiating fin; Design by several runner and gap, can make the radiating fin of radiator have the spacing of higher density and preferable radiating effect, and get so that the bigger heat-sinking capability of radiator performance, can effectively increase the intensity of mould, avoid mould to deform, more can be suitable for mass-produced heat spreader structures.

For further specifying feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet this accompanying drawing only be used to provide with reference to and explanation, be not to be used for protection range of the present utility model is limited.

Embodiment

For above-mentioned purpose of the present utility model, feature and characteristics can be become apparent, a preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below:

Embodiment

See also Fig. 3 and shown in Figure 4, the utility model provides a kind of heat spreader structures that increases area of dissipation that has, especially refer to that a kind of spacing that makes radiating fin obtains the heat spreader structures of higher density and preferable radiating effect, it comprises integrated mould 20 (as Fig. 3), and the volume of these mould 20 integral body can increase or dwindle.

Form several on this mould 20 and be a fixed range and long recess 21 that is provided with at interval and short groove 22, form one in this corresponding two short groove 22,22 and isolate block 24, this long recess 21 and short groove 22 form the shape of " H ", and this mould 20 also can utilize die casting or penetrate the integrated radiator 30 (as Fig. 4) of formation.

The material of this radiator 30 is that the good material of thermal conductivity such as aluminium or copper is made, this radiator 30 can change because of the volume of this mould 20, and can increase or dwindle the volume of this radiator 30, one base 31 is formed on these radiator 30 bottoms, this base 31 can with a cooling base (figure slightly) with gummed, engage or mode such as chimeric links.

Form several long radiating fin 32 and short radiating fin 33 on this base 31, these long radiating fin 32 other two short radiating fins 33 that promptly are provided with, this long radiating fin 32 and 33 formation one of short radiating fin are the shape of " H ", be provided with several runner 34 between this long radiating fin 32 and the short radiating fin 33, this runner 34 can help this long radiating fin 32 and short radiating fin 33 to dispel the heat rapidly.

Form a gap 35 between this corresponding two short radiating fin 33,33, this gap 35 can make the intensity of this long radiating fin 32 and short radiating fin 33 effectively increase, avoid taking place this long radiating fin 32 and 33 distortion of short radiating fin, also can effectively increase the setting of this long radiating fin 32 and short radiating fin 33.
