Abstract

The utility model relates to a liquid flow path board for water-cooling radiator which makes use of two flow path boards with slots to assemble a radiation fin. A liquid flow path is formed between the slots of the two flow path boards, and the radiation fin is affixed on an integrated circuit; when the integrated circuit runs, the heat quantity produced by the integrated circuit can be carried away by the flowing liquid in the liquid flow path so as to decrease the temperature of the integrated circuit.

Description

The liquid flow path plate of water-cooling type radiator

Technical field

The utility model relates to a kind of liquid flow path plate of water-cooling type radiator, relates in particular to a kind of interior liquid flow path plate of water-cooling type radiator of integrated circuit.

Background technology

Along with development of science and technology; the processing speed of integrated circuit is also more and more faster in the computer; usually can install heat abstractor additional on the integrated circuit; the heat that is used for being produced when integrated circuit turned round is distributed to the external world; the processing speed of integrated circuit increases more; the heat that is produced during its running is just big more; then heat abstractor just must have better radiating effect; integrated circuit can be operated normally; reason is overheated and reduce the effect of integrated circuit; known integrated circuit heat dissipation device comprises a kind of water-cooling type radiator; it utilizes a fin to be attached on the integrated circuit; be provided with pipeline in the fin; liquid flows in pipeline; the heat that is produced when utilizing flowing of liquid that integrated circuit turned round is taken away; but the pipeline in the known fin is single stream; it utilizes single pipeline to form bending in fin; though will can increase area of dissipation after the pipeline bending; but its area of dissipation size still can't contain the surface of entire heat dissipation sheet; and the liquid of unit volume is longer by the time of fin; cause cooling rate limited, make the radiating effect of water-cooling type radiator not good, really have its inconvenience in the use.

Summary of the invention

The utility model strengthens area of dissipation because the shortcoming of aforesaid known heat abstractor has designed a kind of liquid flow path plate with the water-cooling type radiator on multithread road, to increase the effect of water-cooling type radiator.

For reaching the purpose of above-mentioned utility model, the utility model has designed a kind of liquid flow path plate of water-cooling type radiator, and wherein, a side of stream plate forms the short slot at a plurality of connection stream plates two ends, two stream plates make up relatively with the short slot side, form liquid flow path between the short slot of two stream plates.

That is to say, in the liquid flow path plate of water-cooling type radiator of the present utility model, stream plate one side forms a plurality of short slots, two stream plates make up relatively with the short slot side, form liquid flow path between the short slot of two stream plates, the stream plate can be used in fin and the radiating seat, and fin and radiating seat utilize water pipe to connect can become one group of water-cooling type radiator, fin is installed on the integrated circuit, and the heat that is produced in the time of integrated circuit can being moved is taken away.

Advantage of the present utility model is, utilize many liquid flow paths in the stream plate, can increase the contact area of liquid and integrated circuit, and then can take away the heat that is produced when more moving by integrated circuit, and utilize the stream plate of two different materials up and down, increase radiating effect.

Embodiment

See also shown in Figure 1ly, the utility model is a stream plate 11, and it can form fin 10.Fin 10 is made up of two stream plates 11, and stream plate 11 materials that contact with integrated circuit 70 can be copper, and another sheet stream plate 11 materials can be aluminium.A side is provided with a plurality of short slots 12 that are parallel to each other and connect stream plate 11 two ends on the stream plate 11.See also shown in Figure 3ly, be formed with the protuberance 13 parallel on stream plate 11 1 lateral margins, be formed with the recess 14 parallel on another lateral margin with short slot 12 with short slot 12.The stream plate 11 that two structures are identical is staggered relatively and fixing with protuberance 13 places and recess 14 places, promptly forms a fin 10.Like this, 12 of the short slots of two stream plates 11 form a liquid flow path 121.See also Fig. 2 and shown in Figure 3, be respectively equipped with the connecting plate 20 of tool accommodation space 201 at the two ends of the opening of the liquid flow path 121 of fin 10.The connecting plate 20 of one side is provided with a water inlet pipe 21, and the connecting plate 20 of opposite side is provided with an outlet pipe 22, and inlet tube and

outlet tube

21,22 communicates with accommodation space 201.

See also shown in Figure 4ly, be provided with one group of radiating fin 30 on fin 10, radiating fin 30 mode such as can weld is fixed on the stream plate 11 of a side, or is formed in one with a stream plate 11 wherein.

Stream plate 11 of the present utility model also can be formed radiating seat 40, see also Fig. 5 and shown in Figure 6, be provided with the wall 401 that separates in the radiating seat 40, be provided with radiating fin 41 between each wall 401, the fin 10 that two stream plates 11 are formed is arranged at respectively in each wall 401, see also shown in Figure 6, respectively be provided with a contiguous block 42 in the two ends of each fin 10 liquid flow path 121, a contiguous block 42 is provided with water inlet pipe 44 therein, another contiguous block 42 is provided with outlet pipe 43, in the arranged outside of radiating fin 41 fan 50 is arranged.
