Abstract

The utility model provides a radiator with a plurality of clustered fins, which comprises a plurality of fin sets and a plurality of heat pipes. Each fin set comprises a plurality of fins laminated at intervals, an assembling hole is formed on the fins of each fin set in a penetrating manner, the assembling holes of the fin sets are arranged corresponding to each other, the heat pipes are arranged inside the corresponding assembling holes of the fins of the corresponding fin sets in a penetrating manner, and heat of a heat source is conducted to the fin sets for heat exchange with environment by the aid of the heat pipes, so that the purpose of radiation is achieved. Each fin set is supplied for one heat pipe for heat exchange, space is formed between clusters formed by the heat pipes and the fin sets, and each heat pipe does not share the same fin set with other heat pipes, thereby relatively improving heat conduction efficiency of the heat pipes. Accordingly, the radiator with a plurality of clustered fins can achieve excellent radiation effect.

Description

Radiator with the formula fin of gathering together more

Technical field

The utility model refers to a kind of radiator with the formula fin of gathering together relevant for a radiator especially, and it is the device that a confession is used to improve heat exchanger effectiveness, promotes the thermal source heat radiation.

Background technology

In equipment such as electronic installation, can produce heat during each electronic component running, the higher electronic component of power consumption particularly, tend to produce high heat, in order to keep the normal operation of these equipment, must on the heat production element, add a heat abstractor,, reach the purpose of arranging its heat that looses to promote and the heat exchange of environment.

Provide multiple different radiator based on the demand prior art, wherein heat-pipe type radiator is a kind of common heat abstractor that is used in the computer apparatus, it mainly runs through same fins group by the complex root heat pipe and is combined, this fins group stacks the fin of putting by plural layer and is constituted, based on this structure, can conduct on each fin of fins group through the heat that electronic component produced of heat pipe, utilize the fin surface to carry out heat exchange with environment and reach the purpose that promotes electronic element radiating desire heat radiation.

Yet, the same fins group of the radiator of prior art is connected with the complex root heat pipe, the water conservancy diversion of air is not good, and between each heat pipe conduct the heat that competitive relation arranged, when thermal source continues heat production, the fins group heat-sinking capability will reach a saturation condition, and distance is close between each heat pipe, to cause the heat pipe near-end and the far-end temperature difference to reduce, thermal conduction rate reduces, so the radiating effect of the radiator of prior art still has to be strengthened.

Summary of the invention

Because the not good disappearance of radiating effect of the radiator of prior art, the purpose of this utility model is to provide a kind of radiator with great heat radiation effect, it is when carrying out thermolysis, can make heat pipe have the heat conduction efficiency of lifting, and make the integral heat sink device reach preferable radiating effect.

In order to achieve the above object, the utility model provide a kind of radiator with the formula fin of gathering together more it comprise plural fins group and plural heat pipe.

Described fins group comprises the fin that plural number is stacking at interval, and each fin runs through the assembly hole that forms a corresponding setting respectively.

Described heat pipe is the closed tube of a hollow, and each heat pipe is arranged in the corresponding assembly hole of fin of fins group of a correspondence, so as to being connected in series the fin of corresponding fins group, gathers together and form one.

Preferable, these heat pipes are little far away from the spacing from an end of fins group with respect to the end near fins group.

Preferable, fin is arranged on the heat pipe by this assembly hole in the form of a ring, and to be formed with plural number on it be center and the air-vent of radial arrangement with the assembly hole.

Preferable, the fin of each fins group is formed with a leg that fixes with heat pipe in the assembly hole periphery.

Based on said structure, radiator with the formula fin of gathering together of the present utility model more, can be just like the prior art radiator, the problem that the most effective thermal conductivity region of each heat pipe overlaps mutually, therefore each fins group can evenly be disperseed the heat energy that each heat pipe is passed out by the heating end, promptly increased the cooling surface area of each heat pipe, and formed the gathering together of each heat pipe and fins group is radial form arrangement, distinguished and admirable can farthest between respectively gathering together, flowing freely in the casing, take away heat, therefore each heat pipe has promoted higher heat conduction efficiency comparatively speaking, and make integral body have to gather together the radiator of formula fin can not need to cooperate fan to use more, can reach better heat radiating effect.

Embodiment

As shown in Figures 1 and 2, the radiator with the formula fin of gathering together of the present utility model more, it comprises plural fins group 10 and plural heat pipe 20.

Cooperation is with reference to figure 3 and shown in Figure 4, described fins group 10 comprises the fin 11 that plural number is stacking at interval, each fin 11 roughly in the form of a ring, and run through the assembly hole 12 that forms a corresponding setting respectively, around the assembly hole 12 by plural number in pairs radially side by side and integrated lamellar body combine, it is center and the air-vent 13 of radial arrangement that each lamellar body is formed with on it with assembly hole 12.

Described heat pipe 20 is the closed tube of a hollow, one end of each heat pipe 20 is arranged in the corresponding assembly hole 12 of fin 11 of fins group 10 of a correspondence, the other end of this heat pipe 20 is connected with a thermal source, so that the heat conduction is caused fins group 10, wherein each heat pipe 20 is little away from the spacing of an end of fins group 10 with respect to the other end near fins group.

With reference to figure 4 and shown in Figure 5, in of the present utility model one preferable specific embodiment, each fin 11 is formed with a leg 14 in assembly hole 12 peripheries, this leg 14 is extended towards an extreme direction of heat pipe 20 by the inner edge place of fin 11, the medial surface of leg 14 and heat pipe 20 tube walls fix, 14 of set legs are between two adjacent fins 11, so as to the distance of 11 of each fins at interval.

Because each fins group 10 comprises the fin 11 that plural number is stacking at interval, and fin 11 formation one of the fins group 10 of heat pipe 20 serial connections one correspondence are gathered together, respectively gather together as the bouquet towards the radial distribution of stow away from heat direction, be to be formed with the space between these fins 11 of each fins group 10 heat pipe 20 formed gathering together corresponding with one, make by each heat pipe 20 conduct the heat that and can carry out heat exchange with environment respectively, to increase overall heat exchange surface area, significantly promote the radiating effect of integral heat sink device according to this.
