Furthermore, in the above technical solution, a positioning slot is provided at one end of the beam; one end of the base extends outward to form a connecting plate, and the other end extends outward to form an insertion plate, and the connecting plate A groove that can be clamped on the beam is formed downward, and the insertion plate is inserted into the positioning slot provided on the beam.

Furthermore, in the above technical solution, hooks are formed extending downwards on both sides of the end of the positioning slot.

Furthermore, in the above technical solution, the display screen is a liquid crystal display screen, and a mounting hole is opened on the bracket, and the display screen is snapped and fixed in the mounting hole.

Furthermore, in the above technical solution, two or more sets of fan blades and bases are installed on the bracket, and the circuit board of the base corresponding to each set of fan blades is electrically connected to the display screen at the same time.

After adopting the above technical solution, the whole structure of the cooling fan described in the utility model is easy to assemble and can be quickly assembled and disassembled. At the same time, a display screen is installed on the bracket for installing the fan blades, through which the fan blades can be displayed. Parameter signals, or display the information of the manufacturer of the product, such as trademarks, logos, etc.

The utility model can be used in various equipment or devices such as computer cases, computer motherboards, graphics cards, CPUs, and automobiles to dissipate heat from main heating devices. It is not only easy to install and disassemble, but also can display relevant information through the display screen. Make users understand the relevant information more clearly.

Fig. 3 is a three-dimensional exploded view of the utility model.

detailed description:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1, 2, and 3, the utility model is a cooling fan, which includes: a bracket 1, a fan blade 2 mounted on the bracket 1, and two fan blades 2 are installed on the bracket 1 in this embodiment , of course, one or more fan blades can also be set as required.

The bracket 1 is a concave plate, and a hole 10 with a diameter larger than that of the fan blade 2 is opened on the plane of its upper end, and the fan blade 2 is located at the position of the hole 10 . A beam 11 is sunk in the hole 10 , and the beam 11 is installed with the base 3 for driving the fan blade 2 to rotate.

The beam 11 is suspended at the hole 10 , and its two ends are integrally fixed with the bracket 1 , and a positioning slot 111 is provided at one end of the beam 11 .

The rotating shaft of the fan blade 2 is connected to the base 3; one end of the base 3 extends outward to form a connecting plate 31, and the other end extends outward to form an insertion plate 32, and the connecting plate 31 is formed downward The insert plate 32 is inserted into the positioning slot 111 provided on the beam 11 .
