Abstract
The utility model relates to a radiation mold group which uses the low-order chip to radiate. The mold group is provided with a base in which a ventilator is provided. A first and a second radiation fin piece group are arranged on the base. A first and a second radiation fin piece group comprise the plural radiation fin pieces with a consistent arranging direction. A first radiation fin piece group is arranged on the two opposite ends of the base. A second radiation fin piece group is arranged in a first radiation fin piece group. The radiation fin pieces on a second radiation fin piece group arrange with gradual rise from inside to outside. The radiation fin piece which is farthest from the ventilator takes the shape folded inward oppositely The radiation mold group makes an external air current enter the base. The air current is not resisted by the radiation fin piece which neighbors the ventilator when blowing to the radiation fin piece. The radiating surface can be increased. The radiation fin piece folded inward oppositely makes the rotational air current of the ventilator to be resisted and not overflow, and rebound to the internal radiation fin piece to increase the amount of wind, the wind speed and the radiating surface.
Description
Technical field
The utility model is relevant for a kind of molding structure of the module that dispels the heat.
Background technology
Generally become known for heat abstractor (as: the multimedia process chip of lower-order, south, north bridge chips etc.), please refer to shown in Figure 1, it is provided with a radiating seat 100, this radiating seat 100 is provided with a base 101, this base 101 is provided with a plurality of marshallings and integrated radiating fin 102, thus, when fan 103 is installed in the radiating seat 100, cause is to be flush state at the height of the radiating fin of fan 103 peripheries, and each radiating fin is to stretch out with radial, therefore its radiation angle also can't be consistent with wind direction, so air-flow that can cause fan to produce, can't flow through between radiating fin smoothly, and extraneous air-flow of coming in also can be subjected to stopping of radiating fin, more can't press close to fan, in addition, this radiating seat 100 is that the development cost of its mould are also higher with the moulding of die casting mode, and therefore cost height and radiating effect are not good in the use.
For improving the various shortcomings of above-mentioned known devices, structure, the inventor is through the permanent research and experiment of making great efforts, and development and Design goes out a kind of heat radiation module finally.
Summary of the invention
The purpose of this utility model is to provide a kind of heat radiation module, when making extraneous air-flow enter in the pedestal, can not stopped, and can increase area of dissipation.
Another purpose of the present utility model is to provide a kind of heat radiation module, can the air-flow of fan rotation can be stopped, and recoiled to the internal layer radiating fin by the radiating fin of inside reflexed, increases air quantity and area of dissipation.
Another purpose of the present utility model is to provide a kind of heat radiation module, can increase air quantity and area of dissipation under the situation of reducing of volume.
The purpose of this utility model is to realize like this, a kind of heat radiation module, it is a kind of heat radiation module that the low order chip cooling is used that is applied to, this heat radiation module is provided with a pedestal, a ccontaining fan in this pedestal, this pedestal is provided with first and second radiating fin group of being made up of the radiating fin of a plurality of orientation unanimities, this first radiating fin is mounted on two ends relative on the pedestal, then be provided with the second radiating fin group between this first relative radiating fin group, the radiating fin on this second radiating fin group is arranged in the shape that raises gradually from inside to outside.
The first radiating fin group is made up of several marshallings and the radiating fin that highly is flush state.
This second radiating fin group radiating fin the most long-range apart from fan is inside reflexed shape, during use, can the air-flow of fan rotation can be stopped, and recoiled to the internal layer radiating fin by the radiating fin of inside reflexed.
Be provided with a depression in the pedestal, this depression can ccontaining fan, and the face of this depression is provided with projection, to increase area of dissipation.
Described pedestal is one-body molded by the aluminium extruded mode.
The height of this fan is not higher than the second radiating fin group radiating fin the most long-range apart from fan.
From the above mentioned, heat radiation module of the present utility model not only can when making extraneous air-flow enter in the pedestal, can not stopped, and can be increased area of dissipation by these radiating fins that raises gradually from inside to outside.

Embodiment
The utility model is a kind of heat radiation module, sees also shown in Fig. 2,3,4, and it is a kind of low order chip (as: multimedia process chip that is used in; South, north bridge chips etc.) the heat radiation module of heat transmission, this heat radiation module is provided with a pedestal 10 by the aluminium extruded moulding, in present embodiment is a rectangle pedestal, be provided with a depression 11 in this pedestal 10, the face of this depression 11 is provided with several projectioies, to increase area of dissipation, and just can a ccontaining fan 20 on this depression 11, and two relative edges on this pedestal 10 are provided with one first radiating fin group 12, this first radiating fin group 12 is made up of several marshallings and the radiating fin that highly is flush state, in addition, then be provided with the second radiating fin group 13 between this first radiating fin group, the radiating fin of this second radiating fin group 13 is arranged in the shape that raises gradually from inside to outside, and this first, the second radiating fin group 12,13 radiating fin orientation unanimity, thus, not only can be by the radiating fin of these second radiating fin groups 13 that raise gradually from inside to outside, when making extraneous air-flow enter in the pedestal 10, can not stopped, and can be increased area of dissipation (as shown in Figure 5).
Moreover, this second radiating fin group 13 is inside reflexed shape apart from fan 20 the most long-range radiating fins, so that when using, can be by the radiating fin of inside reflexed, the air-flow that fan 20 is rotated can be stopped, and recoil to the internal layer radiating fin, so can increase air quantity and area of dissipation (as shown in Figure 5).
Again, the height of this fan 20 is not higher than the most long-range radiating fin in the second radiating fin group 13, therefore, the air-flow that is produced when being rotated by fan 20 can not overflowed by the top of radiating fin, and air-flow can be used for fully the heat transmission of radiating fin, thus, need not increase the size of this fan 20, can increase air quantity, and reduce cost.
In sum, the utility model can improve the various shortcomings of known technology on article, shape, structure, device, can promote effect in the use, closes in practicality, effectively reduces the development cost of mould.
