Description

Radiator fan with rotation speed display function Technical Field The utility model relates to the technical field of radiators, in particular to a cooling fan with a rotating speed display function. Background As the power of electronic devices increases, the amount of heat dissipated increases. Therefore, the heat sink becomes a very common device in electronic equipment. Because the inner cavity of the electronic equipment is relatively closed, and the natural circulation of air is difficult, the radiator and the radiating fan are generally combined to form a radiating module, the radiator is connected with a high-power module of the electronic equipment to transfer and radiate heat, the radiating fan drives the air in the inner cavity of the electronic equipment to flow, and then flowing air flow is formed to bring the heat radiated by the radiator into the external environment of the electronic equipment, so that the aim of improving the radiating efficiency is fulfilled. In a conventional heat dissipation module, an operation parameter of a heat dissipation fan is usually sent to a motherboard of an electronic device, and a display screen of the electronic device is used for displaying a rotation speed. Currently, there are individual heat dissipation modules on the market, which are provided with individual display screens that are flexibly connected to the heat dissipation fan by wires, and then the display screens are mounted on the heat sink. Although the design meets the requirement of individual users on separate display of the rotating speed of the cooling fan, the design has complex structure and large space occupation, and the wiring difficulty in the electronic equipment is increased. Disclosure of utility model Based on the above, the utility model provides the cooling fan with the rotating speed display function, which integrates the display screen and the display control panel on the fixed module of the motor, realizes the installation, fixation and electric connection of the display control panel by utilizing the conductive needle, and the display screen is hidden at the axis of the fan blade, thereby meeting the requirement of a user for independently displaying the rotating speed of the cooling fan, having simple structure and small space occupation, and not increasing the wiring difficulty in the electronic equipment. A cooling fan with a rotation speed display function, comprising: a fan bracket; The fixed die set comprises a stator connected with the fan bracket, a plurality of conductive pins penetrating through the stator, a motor control board positioned at the bottom end of the stator, a display control board positioned at the top end of the stator and a display screen arranged on the display control board, wherein the conductive pins connect the motor control board and the display control board in series on the stator, and the conductive pins realize the electric connection between the motor control board and the display screen control board, and the fixed die set comprises a plurality of conductive pins, a motor control board positioned at the bottom end of the stator, a display control board positioned at the top end of the stator and a display screen arranged on the display control board The movable module comprises a rotor sleeved on the outer periphery of the stator and a fan blade connected with the rotor, wherein the axis of the fan blade is provided with a mounting groove for accommodating the rotor, the top of the axis of the fan blade is provided with a light transmission part, and the light transmission part is positioned above the display screen.
