Description

High-efficiency radiator

The utility model relates to radiator, refer to especially a kind of have preferable radiating effect, soon speed belt from heat, and can avoid heat to be arrested in high-efficiency radiator in the radiator.

Existing heat spreader structures, all be one to be flat base-plates surface and to be provided with a plurality of radiating fins, this radiator is sticked on central processing unit or wafer surface, the thermal conductivity of borrowing radiator itself to be had, with heat by the wafer surface band from, and reach distribute heat and cooling purpose by this radiating fin.In addition,, generally can above radiator, set firmly a radiator fan for the diversion of accelerated heat, borrow air-flow that radiator fan produces with heat rapidly by band between radiating fin from.But in actual use, the air-flow that radiator fan produced, generally the gap by the radiating fin side of radiator enters, discharge through this radiator fan again, make air-flow in flow process, can't be fully with near the heat band of central processing unit or wafer surface from, so radiating effect is not good enough, especially under the situation of wafer high speed development and raising at present, a kind of high efficiency, good heat dissipation effect, as to make central processing unit or wafer operational paradigm height that has must be arranged, can reach the high-efficiency radiator of optimum efficiency.

The utility model main purpose is, at the problems referred to above, providing a kind of can be sticked pedestal in central processing unit or wafer surface, and be embedded with a radiating fin group at the pedestal periphery, between this radiating fin group and pedestal, be formed with a plurality of air flues, can be directly by radiating fin group below, in air flue, flow, and by radiator fan with the heat band from high-efficiency radiator.

The another purpose of the utility model is: provide a kind of formed air-flow of radiator fan that can make more near the surface of central processing unit or wafer, more help with the fast speed belt of heat from, and can avoid air-flow between radiating fin, to produce the high-efficiency radiator that the retardance situation takes place.

The utility model is achieved through the following technical solutions: a kind of high-efficiency radiator, mainly comprise pedestal, radiating fin group, and it is characterized in that: a base bottom is equipped with a flange, and the side peripheral region is convexly equipped with a holding section; One radiating fin group has the framework that is hollow in, can be embedded on the pedestal, be positioned on the holding section of pedestal side periphery, framework inner peripheral surface place equidistantly is equipped with a plurality of radiating fins, and between this radiating fin and pedestal, forming a plurality of air flues of a favourable airflow, this framework lateral surface also is provided with a plurality of radiating fins in addition.

The utility model also can be realized like this: the surface, holding section on the said base is provided with a plurality of heat radiation conduits or the side periphery in the holding section equidistantly is equipped with a plurality of radiating fins, and this radiating fin end is provided with an end face portion; Above-mentioned radiating fin group has the framework that is hollow in, the equidistant symmetrical ring in framework inner peripheral surface place is provided with a plurality of radiating fins, make that forming a through hole in this radiating fin centre can be embedded on pedestal, is positioned at the surface and is provided with on the holding section of a plurality of heat radiation conduits.

Above-mentioned radiating fin group has the framework that is hollow in, the equidistant symmetrical ring in framework inner peripheral surface place is provided with a plurality of radiating fins, can directly be embedded on pedestal, be positioned at the side periphery and equidistantly be equipped with a plurality of radiating fin ends and be provided with on the holding section of end face portion.

The utility model is owing to form a plurality of air flues of a favourable airflow between radiating fin and pedestal, can be directly by radiating fin group below, in air flue, flow, and borrow the air-flow that radiator fan produced fast the heat of pedestal and radiating fin up to be discharged or down guide, with the fast speed belt of heat from, avoided air-flow between radiating fin, to produce the retardance situation,, the operational paradigm of central processing unit or wafer has been improved so improved the radiating effect of radiator.

The utility model further specifies by the following drawings and embodiment:
