This paper relates to an axial fan of a forward-leaning computer, in particular to an axial fan of a forward-leaning computer used for a heat dissipation device of a computer central processing unit (CPU). heat dissipation fan , It makes the cooling air blow to the hotter central bottom area in the heat sink first, and then blow the wind direction 4 week export, in order to achieve the effect of heat dissipation.

  Computers are a must for modern people electronic information products, almost everyone has a machine. The operation of the computer depends entirely on the central processing unit. When running, a high temperature is bound to be generated, and if the heat is not dissipated when the high temperature is generated, the computer will run currently unstable status 。

  Therefore, the CPU is usually equipped with a heat dissipation fan to dissipate the generated high temperature. However, the heat dissipation devices in general computers are mainly composed of heat dissipation seats, heat dissipation fins and fans. However, the heat sink and heat sink will generate high temperature, the use of heat sink concave and convex structure to spread it out. It mainly uses the operation of the fan to lead out the heat and achieve the heat dissipation effect. Therefore, the design of the fan in the heat sink is closely related to the execution stability of the CPU. How to make the central processing unit

  Fig.1 is a well-known heat dissipation fan, mainly comprising a heat dissipation base 1, a heat dissipation fin 2 and a fan 3, wherein:

  The heat dissipation seat 1 is a flat plate, and the upper edge of the heat dissipation seat 1 is provided with heat dissipation fins 2. The fan 3 is arranged on the heat sink 2, and the fan blades 31 of the fan 3 are horizontal. During operation, the fan blades 31 of the fan 3 rotate to blow air into the lower fins. When the wind flows out around, follow then take away the heat from the heat sink to achieve the heat dissipation effect.

  However, due to the following reasons:

  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.the fan normally installed on the heat dissipation seat, when in operation, guides the wind in a counterclockwise or clockwise spiral direction.usually, the wind only reaches the heat dissipation at the outer ring circumference, while the middle position is almost in a calm state, which cannot make the highest temperature central part reach the heat dissipation effect.

  The invention aims to provide a forward-leaning computer axial flow heat dissipation fan, which can achieve the purpose of rapidly dissipating heat at high temperature scattered at the central part of a central processing unit.

  In order to achieve the above purpose, the utility model provides a forward tilting computer axial flow fan, which is provided with a heat dissipation seat provided with radiating fins, wherein the fan blades of the fan are inclined downwards.

  Features and advantages of this product:

  1.The forward-leaning computer axial-flow heat dissipation fan in this paper has downward inclined fan blades. When the fan rotates, the cooling air can be concentrated to the hotter central bottom area in the heat dissipation seat (because the central part is the hottest place), so as to achieve better heat dissipation effect 。

  2.The forward-leaning computer axial-flow heat dissipation fan of the utility model utilizes the fan blades of the fan to be inclined downward, so that the central processing unit can quickly achieve the heat dissipation effect, and the operation of the computer can not generate the unstable phenomenon of the execution system.
