Detailed Description

The terminology used in the description of the embodiments of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the application, as the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The electronic equipment comprises a case, a circuit board and electronic components, wherein the circuit board and the electronic components are arranged inside the case, and the electronic components are electrically connected to the circuit board. The electronic components include, but are not limited to, chips, capacitors, resistors, graphics processors, memories, network cards, and power supplies, which are used to implement the functions of the electronic device. When the electronic equipment is powered on and works, most electronic components on the circuit board generate heat, so that the temperature of the electronic components is increased, and the performance is reduced.

In order to ensure the performance of the electronic components, the heat generated by the electronic components inside the chassis of the electronic device needs to be dissipated in time to prevent the temperature of the electronic components from continuously rising. At present, the heat dissipation methods of electronic devices mainly include two types: the first heat dissipation method is liquid cooling heat dissipation, and the second heat dissipation method is air cooling heat dissipation.

The air-cooled heat dissipation needs to be provided with an air-cooled heat dissipation assembly inside a chassis of the electronic device, and the air-cooled heat dissipation assembly comprises a radiator and a heat dissipation fan. One side of the heat sink is generally attached to an electronic component such as a chip, which requires heat dissipation, through a thermal interface material, and the other side of the heat sink generally has heat dissipation fins arranged at intervals. The heat radiation fan is arranged close to the heat radiator. The case is provided with an air inlet and an air outlet. The cooling fan can drive cold air to enter the interior of the case through the air inlet hole, the cold air can carry out heat convection among the cooling fins of the radiator, and hot air formed after heat exchange leaves the case through the air outlet hole so as to reduce the temperature of electronic components in the case and ensure the performance of the electronic components.

Fig. 1 is a schematic structural diagram of a heat dissipation fan in the related art. As shown in fig. 1, in the related art, a heat dissipation fan 100 ' includes a mechanical part 110 ', the mechanical part 110 ' includes a fan frame 111 ' and a fan assembly 112 ', the fan frame 111 ' has a receiving window 1111 ', and the fan assembly 112 ' is installed in the receiving window 1111 '. When the heat dissipation fan 100 ' is installed at a predetermined position of the electronic device, the cable 130 ' of the heat dissipation fan 100 ' may be connected to a motherboard of the electronic device, so that the motherboard of the electronic device drives and controls the heat dissipation fan 100 ' via the cable 130 '.

Fig. 2 is an exploded view of a heat dissipation fan in the related art. As shown in fig. 2, in the related art, the heat dissipation fan 100 'further includes an electronic component 120', and the electronic component 120 'may be a driving control board of the heat dissipation fan 100'. The fan assembly 112 ' of the heat dissipating fan 100 ' includes a stator 1121 ', a rotor 1122 ', and fan blades 1123 '. One end of the receiving window 1111 ' of the fan frame 111 ' is provided with a supporting frame 1112 ', the electronic component 120 ' is received in the receiving window 1111 ', and the electronic component 120 ' is fixedly connected with the supporting frame 1112 '.

Because the mechanical parts of the cooling fan are generally high in reliability, the probability of failure within a preset service life is low; compared with mechanical components, electronic components have lower reliability and higher failure probability within a preset service life. Therefore, when the electronic parts of the heat dissipation fan in the related art are failed or fail, the heat dissipation fan needs to be directly replaced. However, this approach wastes mechanical parts of the heat dissipation fan, resulting in a relatively high maintenance cost of the heat dissipation fan.

Based on this, the embodiment of the application provides a cooling fan, an electronic device and a server. Wherein, the radiator fan includes mechanical part and electronic parts. By arranging the mechanical part and the electronic part in a split manner, on one hand, the electronic part can be replaced without disassembling the mechanical part of the cooling fan when the electronic part fails or fails, so that the operation is simple and convenient, and the time is saved; and the mechanical parts of the cooling fan can not be wasted, and the labor cost and the equipment cost for maintaining the cooling fan can be further reduced.
