Computer radiating fan combined by fan and radiating fin

Back to list Release date: Jul 30, 2019

  This article mainly talks about a kind of computer cooling fan , which is installed on the inclined plate body and part of the cut cooling fins, so that the wind can be quickly introduced into the hotter middle and lower parts to achieve better cooling effect for the computer central processing unit (CPU)

Heat sink.

  Computers are essential electronic information products for modern people, and now almost everyone owns one. The operation of the computer depends entirely on the central processing unit.During the operation, high temperature will certainly be generated through power transmission.If the high temperature is not generated

Heat dissipation will make the computers operation and execution system unstable.Therefore, a heat dissipation fan is usually installed on the CPU to dissipate the generated high temperature.

  Referring to fig.1, the conventional heat dissipation fan mainly includes a heat dissipation base and a fan, wherein:the heat dissipation base is a flat plate with a heat sink on its upper edge; And the fan of the fan is arranged on the radiating fin, and corresponding fixing holes are respectively arranged at each end angle of the fan and the radiating seat

And a screw hole, the heat dissipation seat and the fan are combined into a body through a screw, and then the heat dissipation fan is arranged and formed with the central processing unit.

  With the above structure, when the computer is in operation, the fan starts to rotate at the same time, so that the wind blows to the heat dissipation blades and the central processing unit to achieve heat dissipation.However, due to:

  1.Since the central processing unit is located at the center of the heat sink, the temperature at the lower part of the center of the heat sink is the highest temperature, whereas the heat dissipation here is usually not easy.

  2.When the fan normally arranged on the heat dissipation seat is running, the wind is introduced in a spiral way in a counterclockwise or clockwise direction.Usually, the wind can dissipate heat only at the outer ring circumference, while the middle position is almost in a windless state, thus the heat dissipation effect cannot be achieved at the center part at the highest temperature.

.

  The computer radiating fan combined by the fan and the radiating fin utilizes the device to achieve the effect of rapidly radiating heat at high temperature scattered at the central part of the central processor. In order to achieve the above purpose, the utility model provides a computer heat dissipation wind combined with a fan and a radiating fin.

The fan is formed by combining a heat dissipation seat, a fan and an air guide cover, wherein the bottom plate of the heat dissipation seat is matched with a flat plate formed in a central processing unit scale, an inclined plate body is extended on one side edge of the flat plate, and the upper end surface of the bottom plate of the heat dissipation seat is provided with a series of radiating fins and is close to the fan side

The whole row of radiating fins are cut into cambered surfaces;

  The fan assembly is arranged on the inclined plate body of the heat dissipation seat, and an air guide cover is arranged from the upper part of the top end of the fan to the central position of the heat dissipation fin.

  The side edge of the bottom plate of the heat dissipation seat can be extended upward for a height before extending the inclined plate body. The utility model has the following characteristics and advantages:

  (1) The utility model is a computer heat dissipation device with a combination of a fan and a heat sink.The fan is arranged on the side surface of the heat sink, so that the wind force can form a side blowing mode.As the flow field of the side blowing mode is smooth, the wind can be smoothly blown to the central part (because the central part is

The highest temperature), in order to achieve the effect of heat dissipation.

  (2) The utility model is a computer heat dissipation device combined with a fan and a heat dissipating sheet.The fan group is arranged on the inclined plate body of the heat dissipation seat to form an inclined angle.When the fan is running, the wind direction of the fan can be blown downwards to the central bottom position of the heat dissipation seat (due to the center

The location is the highest temperature).

  (3) The utility model is a computer heat dissipation device combined with a fan and a radiating fin, which utilizes the first row of heat dissipation:the design that the slices are cut off in an arc shape can reduce the wind resistance, and the wind can be quickly led into the central part (because the central part is the highest temperature place) to achieve the heat dissipation effect.

  (4) The utility model is a computer heat dissipation device with a combination of a fan and a heat sink.The fan to the heat sink is provided with a wind guide cover with a smooth curve, which can guide the wind blown by the fan to the central part to prevent the sucked wind from flowing out, thus improving the efficiency.

  The embodiment of the utility model will now be described in further detail with reference to the attached drawings.

  Please refer to fig.2, which is a three-dimensional appearance schematic diagram of the utility model.the utility model is a computer heat dissipation device 1 combined with a fan and a radiating fin, which is composed of a heat dissipation base 10, a fan 20 and a wind guide cover 30, wherein:

  The bottom plate 101 of the heat sink 10 is matched with a flat plate formed in the central processing unit A dimension, and an inclined plate body 102 is extended on one side edge of the flat plate.The upper end surface of the bottom plate 101 of the heat sink 10 is provided with a plurality of rows of radiating fins 103, and the entire row of radiating fins-  close to the fan 20 side. 103,

The cutting is curved 104. The fan 20 is assembled on the inclined plate 102 of the heat dissipation base 10, a smooth air guide cover 30 is arranged from the top of the fan 20 to the appropriate position of the heat dissipation month 103, and two sides of the air guide cover 30 to the heat dissipation fin 103 are respectively extended downward

301, which is loc on that bottom plate 101 of the heat sink 10 to reach a fixed setting position.

  Please continue to refer to fig.3.when the computer is running, a higher temperature will be generated at the position of the central processing unit.at this time, the fan 20 arranged on the side is used to suck in the wind, and the side is blown into the radiating fins 103, and the radiating fins 103 in the first row are of arc-shaped 104 design.

In addition, the wind can be rapidly introduced into the central part, while the inclined plate 102 can make the wind direction downward and make the wind blow to the central bottom position of the heat dissipation seat 10 (because the central part is the highest temperature place) to achieve the heat dissipation effect.

  In addition, the smooth air guide cover 30 provided on the fan 20 to the heat sink 103 guides the air blown out of the fan to the central part, which can also prevent the sucked air from flowing out, thus improving the efficiency.

  In addition, under the space limitation of computer parts assembly, one or more fans of the utility model are combined with radiating fins. The inclined plate body in the computer heat dissipation device can be extended upward by an appropriate height from the side edge of the bottom plate of the heat dissipation seat, and then the inclined plate body can be extended (as shown in fig.4).by using this

The method enables the space at the heat dissipation seat and the inclined plate body to be matched with the space application when computer parts are assembled.
