Abstract

The utility model relates to a heat dissipating device, which is characterized in that a flat-type heat pipe and a heat conducting fin are arranged between a base and a heat-dissipating fin group, wherein an accommodating groove is arranged on the heat conducting fin in a penetrating way, and the flat-type heat pipe is embedded in the accommodating groove. Accordingly, when the utility model is arranged on a central processing unit and other electronic components, the heat absorbed by the base is conducted to the flat-type heat pipe, is evenly diffused by the flat-type heat pipe and the heat conducting fin surrounding the flat-type heat pipe, and then is emitted into the air by the heat-dissipating fin group so as to effectively cool the central processing unit.

Description

Heat abstractor

Technical field

The utility model relates to a kind of heat abstractor, particularly relates to being provided with flat heat pipe and having great heat radiation effect and can be made as the heat abstractor of a reduced size.

Background technology

Progress along with material and technology, be used in the computer in order to processing instruction, the CPU of data or the like, frequency during its operation constantly rises, the calculation ability also improves thereupon, but incident is that caloric value also significantly increases, because the rising of temperature can cause CPU usefulness to reduce during running, therefore how to make the exploitation of the thermal management technology that this heat effectively disperses also enjoy attention, particularly be applied to the occasion of server when this CPU, because server special requirement when operation need keep stability, therefore for the requirement of radiating effect than general computer height, so will and be formed at the heat abstractor that radiating fin constituted on this copper/aluminium block by one bronze medal/aluminium block in the prior art and be positioned over the mode of dispersing in order to supplemental heat the CPU top and do not met demand;

For improving the deficiency of above-mentioned heat dissipation technology, then there is the dealer to develop the technology that copper/aluminium block integral body is replaced with a heat pipe, so can absorb the heat of CPU and heat is evenly distributed in order to being distributed by radiating fin by this heat pipe, but the manufacturing cost of heat pipe is higher, thereby the shortcoming that has the cost that causes heat abstractor significantly to rise;

In addition, the overall dimensions of server are to be formulated by EIA (EIA) standard specification is arranged, can be divided into as the rack type version server 1U or 2U etc. are arranged, wherein this U is meant the height of server, 1U equals 4.445cm, therefore the server of 1U specification its highly be 4.445cm, by that analogy, the external form of hence one can see that server is to have certain height, so its overall dimensions of heat abstractor of using for server also are restricted, therefore how designing with low cost in limited size range and have the heat abstractor of great heat radiation effect, is the problem that the utility model institute desire solves.

Summary of the invention

Because the problem of above-mentioned existing heat abstractor, the purpose of this utility model provides a kind of heat abstractor, and it also can not cause cost significantly to increase except having great heat radiation effect.

For achieving the above object, the utility model provides a heat abstractor, and it includes:

One pedestal is by the made lamellar body of Heat Conduction Materials such as copper, aluminium;

At least one flat heat pipe, it is arranged on the described pedestal upper side;

One conducting strip, be by the made lamellar body of the Heat Conduction Material identical or different with pedestal, it runs through the storage tank that is formed with the described flat heat pipe external form of coupling, conducting strip is arranged on the described pedestal flat heat pipe is embedded in the storage tank, and the end face of its end face and flat heat pipe is in the same plane;

One radiating fin group includes a plurality of fins that are set in distance, and the radiating fin group is arranged on described conducting strip and the flat heat pipe.

The utility model in use, the central processing unit etc. that is arranged at server has the electronic component top of radiating requirements, and make described pedestal contact with the central processing unit surface, the heat that this central processing unit like this is produced when operation can conduct on the pedestal, this heat and spread for described flat heat pipe absorbs apace along heat pipe, and further conduct to the described conducting strip that surrounds flat heat pipe, heat can evenly be distributed, then distribute in air via described radiating fin group.

From the above, the utility model is by described flat heat pipe and conducting strip heat evenly to be distributed in order to dispersing from radiating fin, its radiating effect is better than the existing heat abstractor that does not use heat pipe, and cost of manufacture also is lower than the existing heat abstractor that copper/aluminium block integral body is replaced with a heat pipe, and, therefore can produce the less heat abstractor of size to be used on server owing to be to use flat heat pipe.
