Abstract
The utility model discloses a radiating plate for a video card. The radiating plate consists of a radiating plate substrate and radiating fins upwards extending from the radiating plate substrate, and is characterized in that the radiating plate substrate is made of an aluminum alloy material; a row of radiating fins is arranged at the top of the radiating plate substrate; two cavities are formed in each radiating fin, and are symmetrically shaped, so that the radiating fin is 'M'-shaped; the periphery of the radial section of each cavity is enclosed; and at least two auxiliary radiating fins are arranged on each of the left and right sides of each radiating fin. The radiating plate is rational in design, and is made of the aluminum alloy material so as to be high in thermal conductivity and radiation speed; and due to the arrangement of structures such as the cavities, a radiation area is effectively enlarged under the condition of no increase of size of the radiating plate, and improvement on the radiation efficiency is facilitated.
Description
Technical field
The utility model relates to the technical field of cooling system, especially a kind of heat radiator that is used for video card.
Background technology
The a large amount of universal use of computer at present, computer fittings such as the central processing unit on the computer, video card can produce great amount of heat in operational process, if it is not effectively lowered the temperature, will influence the operate as normal and the serviceable life of electronic component so.So on computer fittings such as central processing unit, video card, generally be provided with heat abstractor.Existing heat abstractor mainly comprises a thermal-arrest seat, heat radiator and the auxiliary fan that dispels heat; The heat radiator that is used for video card; Mainly comprise the heat radiator matrix, form the perpendicular tooth that extends up at this heat radiator matrix, this structure is when reality is used; Because area of dissipation is not enough, causes radiating effect not reach requirement.
The patent that our company has applied for: the patent No. 200920056890.2 provides a kind of reinforced heat radiator of the high power flank wing that is used for video card; This heat radiator matrix forms the heat radiation lamellar body that extends up; On two flanks of heat radiation lamellar body, increase the bluff bit that has side to stretch; Radiating surface through bluff bit increase product promotes radiating effect.This structure is to adopt increase heat radiation bluff bit to enlarge area of dissipation, though adopt the method to have better heat radiating effect, increases the use that the heat radiation bluff bit can increase material, and the while structure is comparatively complicated, is unfavorable for producing.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned technology, provides a kind of simple in structure, the high and lower-cost video card heat radiator of radiating efficiency.
The technical scheme that the utility model is realized is following: a kind of video card heat radiator; By heat radiator matrix and constituting by the upwardly extending radiating fin of heat radiator matrix; It is characterized in that: row's radiating fin is arranged at the top of the said heat radiator matrix of being processed by aluminum alloy materials, and said radiating fin is " M " shape, is provided with the cavity of two shapes symmetries in it; The all around sealing of said cavity in radial section, the left and right sides of said radiating fin is provided with at least two heat radiation bluff bits vertical with radiating fin.
As the further improvement of the utility model embodiment, described cavity left and right sides inwall is a zigzag structure.
The utlity model has following advantage:
The utility model adopts aluminum alloy materials to make; An extrusion modling; The cavity of two shape symmetries is arranged in each radiating fin, and the left and right sides inwall of each cavity is a zigzag structure, and each increase of the both sides of radiating fin has the heat radiation bluff bit; Effectively increase area of dissipation under the situation that makes the heat radiator volume not increase, helped the raising of radiating efficiency.Because the existing like product of the utility model has reduced the use of heat radiation bluff bit, effectively reduce the use of material simultaneously, reduce production costs.
Description of drawings
Fig. 1 is the radial section structural representation of the utility model video card heat radiator.
Fig. 2 is the enlarged drawing of the cavity A portion of the utility model video card heat radiator.
Among the figure, 1-heat radiator matrix, 2-radiating fin, 3-cavity, the 4-bluff bit that dispels the heat.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
As shown in Figure 1; The utility model is by heat radiator matrix 1 and be made up of heat radiator matrix 1 upwardly extending radiating fin 2, and wherein, described heat radiator matrix 1 is processed by aluminum alloy materials; One row's radiating fin 2 is arranged at the top of heat radiator matrix 1; Be provided with the cavity 3 of two shape symmetries in the radiating fin 2, make radiating fin 2 be " M " shape, all around sealing of cavity 3 in radial section; The left and right sides of radiating fin 2 is provided with at least two heat radiation bluff bits 4, and heat radiation bluff bit 4 is vertical with radiating fin 2.
In the present embodiment, each increases in the both sides of radiating fin 2 has 12 heat radiation bluff bits 4, and heat radiation bluff bit 4 is evenly distributed from top to bottom.As shown in Figure 2, the left and right sides inwall of cavity 3 is a zigzag structure, and zigzag structure increases the area of dissipation of cavity 3.
Claims (2)
1. video card heat radiator; By heat radiator matrix and constituting by the upwardly extending radiating fin of heat radiator matrix; It is characterized in that: row's radiating fin is arranged at the top of the said heat radiator matrix of being processed by aluminum alloy materials, and said radiating fin is " M " shape, is provided with the cavity of two shapes symmetries in it; The all around sealing of said cavity in radial section, the left and right sides of said radiating fin is provided with at least two heat radiation bluff bits vertical with radiating fin.
