Description

Heat abstractor

[technical field]

The utility model has about a kind of heat abstractor, espespecially a kind of have can save material and the degree of depth that can control containing hole and the top side and the bottom side evenness that maintain substrate, and then also effectively reach the heat abstractor of effect of samming.

[background technology]

In recent years along with the fast development of information, communication and opto-electronics, electronic product moves towards high-order and lightening gradually, under the demand of high speed, high-frequency and miniaturization, the heat generation density of electronic component is more and more higher, and therefore radiating efficiency has become the key factor determining electronic product stability; Because heat pipe or conducting strip have high efficiency thermal conduction characteristic, be one of heat conducting element of extensive use in electronic product.Heat pipe or conducting strip are mainly by the airtight vacuum copper pipe or the copper sheet that have capillary layer at its wall sintering, the working fluid in pipe is utilized to absorb thermal source (as CUP etc.) at evaporation ends and gasify, the steam of heating end condenses into liquid and capillary force effect by capillary layer is back to evaporation ends at condensation end after heat radiation (such as with radiating fin and fan etc.), forms a sealing and circulating.

Mainly comprise as TaiWan, China patent gazette Application No. the 097202791st discloses a kind of radiator: a pedestal, this pedestal has the first relative side and the second side, the first side of this pedestal offers a S connected in star; One S shape heat pipe correspondence is arranged in this S connected in star; And complex cooling fin is arranged on the first side of this pedestal; It is characterized in that: the first side of this pedestal also offers at least one U-shaped groove, the opening of described U-shaped groove towards the opening in two openings of this S connected in star, so that an opening portion of described S connected in star is closed; And this radiator also comprises at least one U-shaped heat pipe, described U-shaped heat pipe correspondence is arranged in described U-shaped groove, and wherein the heat accumulating in this base central can be transmitted to the edge of this pedestal by this S shape heat pipe and this U-shaped heat pipe rapidly.When the S connected in star of pedestal and U-shaped groove are in time being formed in known technology, S connected in star and U-shaped depth of groove wayward and have tolerance issues, and when S connected in star and U-shaped Pocket Machining are formed, its Stress Release causes pedestal poor with the back side (i.e. the side of the relative lower shoe of the pedestal) levelness of U-shaped groove in S connected in star 111, and then causes this pedestal to correspond to S connected in star and U-shaped groove front and S connected in star and the U-shaped groove back side cannot to distinguish the problem effectively attaching fin and heater element (as central processing unit or pattern processor).Separately, because pedestal uses copper material many, this pedestal preponderance is caused.

The above, known technology has its own shortcomings:

1. preponderance.

2. consume material.

3. groove has tolerance issues.

4. back side levelness difference (or poor flatness) of pedestal.

Therefore how will solve the above-mentioned problem commonly used and disappearance, the utility model people being this case and the relevant manufactures being engaged in the industry desire most ardently the place, direction studying improvement.
