Abstract

The utility model relates to a horizontal radiator design, which comprises a plurality of heat sink fins, a plurality of duct heaters and a pedestal which are combined closely. The duct heaters are provided with planished parts at the selected positions and are exposed at the bottom of the pedestal, which ensures that the duct heaters can be closely contacted and clung to the heat dissipation part of an electronic chip, thus ensuring the heat conducting from the electronic chip to the duct heaters immediately, so as to bring better heat dissipation function and achieve the purpose of fast heat conduction and heat dissipation. Due to the compact combination of all whole component assemblies, soldering is unnecessary, which can be in accordance with the environmental protection principle completely.

Description

Horizontal radiator

Technical field

The utility model provides a kind of horizontal fansink designs, refer in particular to each main member all be the close-fitting state in conjunction with forming, utilize the exposed heat radiation position of being located at the bottom surface of base and directly pasting the sub-chip that gets an electric shock of heat pipe, make Re Wen can conduct to heat pipe rapidly, to obtain better heat sinking function.

Background technology

Known radiator with heat pipe composition, except a plurality of heat pipes, its formation still comprises a plurality of radiating fins and a base, radiating fin adopts aluminium matter or copper material usually, known heat pipe then is the metal tube of two ends sealing, its inside is filled with working solution, described base is also adopted aluminium matter or copper material, therefore be commonly called as again in " at the bottom of the aluminium " or " at the bottom of the copper ", known heat spreader module is a unlike material because of heat pipe and base, thus need could use tin cream or bonding agent heat pipe and base to be imposed soldering with the electronickelling processed in advance as the welding media, so overall package or all suspicion complexity of manufacturing, cost is higher, fraction defective is also higher, and the heat conduction efficiency of base and heat pipe also can reduce, and soldering processing, also cause environmental pollution, not compliance with environmental protection requirements easily.

Above-mentioned known radiator, mainly be to paste with the heat radiation position of electronic chip with base (at the bottom of the aluminium or at the bottom of the copper) to touch, the hot temperature of electronic chip is conducted to base earlier, conduct to heat pipe and radiating fin by base again, and reach the heat radiation purpose, therefore, its hot temperature conduction system is adopted indirect mode, earlier be passed to heat pipe and radiating fin again, so efficient is comparatively slow by base.

The utility model content

The main purpose of the utility model is to provide a kind of horizontal fansink designs, close-fitting is formed in conjunction with institute by comprising a plurality of radiating fins, a plurality of heat pipe and a base, the heat pipe pipe shaft has the pressed flat that can be exposed to base end face, make base half-naked coating heat pipe and be firm combination, being to paste fully and touching because of the exposed part system of heat pipe and electronic chip heat radiation position, can be by the heat pipe discharging of directly the hot temperature of electronic chip being dispelled the heat rapidly, so do not have the disappearance of transmitting heat radiation indirectly, radiating efficiency is very quick.

The secondary objective of the utility model is to provide a kind of horizontal fansink designs, the combination that is mutual close-fitting because of each member is formed, so can present the combination of propping up of close-fitting state more when meeting thermal expansion, help to improve heat conduction, radiating efficiency, and do not need soldering whole the composition fully, also need not to use the electronickelling processed, so do not pollute the environment compliance with environmental protection requirements more.

Another purpose of the utility model is to provide a kind of horizontal fansink designs, described base is offered the open shape caulking groove that a plurality of and heat pipe are mutual coupling in the bottom surface, between each caulking groove and be provided with strip folder rib, after making heat pipe coupling embed caulking groove, and can utilize the clamping of strip folder rib and obtain firm clamping location.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1 to Figure 3, the utility model do " horizontal radiator " design, its composition comprises: a plurality of radiating fins 1, a plurality of heat pipe 2 and a base 3, wherein:

A plurality of radiating fins 1, its adjacent spaces is piled up and is a block heat radiation pedestal 10 of arranging, offer through hole 11 on the radiating fin 1, run through the heat radiation pedestal 10 that this bulk is arranged for heat pipe 2 close-fittings, and can be provided with the gap slot 12 of suitable shape in the lower edge of radiating fin 1, for to form coupling chimeric with base 3 upper surfaces;

A plurality of heat pipes 2, be that the bent tubular body that is J-shaped or U-shaped is all sealed at two ends, working solution is also loaded in body inside, body has two

adjutages

21,22, an adjutage 22 wherein lies in the bottom moulding and is provided with pressed flat 23 (as Fig. 4), after heat pipe 2 close-fittings embed base 3, make that pressed flat 23 is the bottom surface that is exposed to base 3, and be and trim corresponding same plane;

Base 3, be a solid metal pedestal (can adopt copper or aluminium matter), the upper surface has heat radiation pedestal 10 lower edges of arranging with bulk and is the relative groove face 31 of coupling, the open shape caulking groove 32 that a plurality of and heat pipe 2 are mutual coupling is offered in the lower surface, between each caulking groove 32 and have a strip folder rib 33, after heat pipe 2 couplings embed caulking groove 32, utilize strip folder rib 33 to impose the clamping location and be the close-fitting combination;

Utilize the mutual close-fitting combination of above-mentioned a plurality of radiating fin 1, a plurality of heat pipe 2 and base 3, heat pipe 2 semi-nudities are coated on base 3, the pressed flat 23 that makes heat pipe 2 is for being exposed to base 3 bottom surfaces, mat pressed flat 23 is touched with the direct subsides at electronic chip heat radiation position, can absorb the hot warm of electronic chip and directly heat radiation discharging by heat pipe 2, so do not need the indirect transfer heat radiation, its radiating efficiency is very quick.

Because adopting mutual close-fitting, each member of the present utility model forms, combination stability is good, the non-loosening or the possibility that comes off, its assembly also simple and easy fast and cost low, the pressed flat 23 of described again heat pipe 2 is directly to paste the heating position that touches at electronic chip, so radiating efficiency is better, and also need not soldering whole the composition, can not pollute environment, meet environmental friendly principle fully.

The above-mentioned a plurality of open shape caulking groove 32 of being located at base 3 bottom surfaces, its strip folder rib 33 between each caulking groove 32, system can offer the V-shaped groove 331 (as Fig. 4) of an extension shape in advance, after making heat pipe 2 couplings embed caulking groove 32, can utilize the distortion pressing of V-shaped groove 331 both sides, what make V-shaped groove 331 can and tightly be resisted against heat pipe 2 to the bending of both sides bifurcated, and then forms good embrace fixing (as Fig. 4, shown in Figure 5) with heat pipe 2.

The above, it only is the preferred embodiment of a kind of horizontal radiator of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
