Description

Technical Field

[0001] This utility model relates to the field of waterproof fans, specifically a waterproof fan that can be produced quickly and dissipates heat rapidly. Background Technology

[0002] A waterproof fan is a specially designed electric fan primarily used in environments requiring waterproofing, moisture resistance, and corrosion resistance. It utilizes a waterproof casing and special processing techniques, along with protective measures such as potting and waterproof coatings on the internal circuitry, to create an effective waterproof barrier. This ensures the equipment operates normally and stably in humid or rainy environments, preventing moisture damage to the internal circuitry.

[0003] Most DC waterproof fans on the market use injection-molded or potting sealant to completely enclose the stator. Since the stator generates heat during operation, if the power is low, the heat generation is minimal, and the product is safe. However, if the power is high, the heat generation is significant, and the temperature rises, the product may crack and be damaged. Therefore, there is room for structural improvement. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waterproof fan that can be produced quickly and dissipates heat rapidly, comprising a fan frame, a stator and a fixture, wherein the stator is inserted and fixed inside the top of the fan frame, the fixture is sleeved on the outside of the bottom of the fan frame, and four sets of heat dissipation windows are evenly opened on the inner side of the fan frame.

[0005] Preferably, the fan frame includes a housing body, a stator slot, a limiting protrusion, and a wire groove. The stator slot is centrally located at the top of the housing body, the limiting protrusion is centrally fixed inside the stator slot, and the wire groove is located at the top of the housing body.

[0006] Preferably, the four sets of heat dissipation windows are formed through the outer wall of the stator slot.

[0007] Preferably, the stator is inserted into the stator slot to fix it to the outer frame of the fan, and the limiting protrusion is inserted into the stator.

[0008] Preferably, the stator's wires are fixed inside the wire groove and pass through the housing body.

[0009] Preferably, the fixture is sleeved on the outside of the stator slot, and the four sets of heat dissipation windows are located between the stator and the fixture, with the fixture sealing and wrapping the four sets of heat dissipation windows.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention proposes a waterproof fan that can be produced quickly and dissipates heat rapidly. The waterproof fan uses coils to wrap around the silicon steel sheets inside the fan frame. The opening of the heat dissipation window allows the silicon steel sheets to be partially exposed. The coils are the part that generates a lot of heat during use. The stator can be wrapped by a jig and then potted with glue. After potting, the PCB and electronic components can be sealed, thereby solving the overall waterproof problem of the fan and greatly improving production efficiency. Attached Figure Description

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a waterproof fan that can be produced quickly and dissipates heat quickly, including a fan frame 1, a stator 2 and a fixture 3.

Four sets of heat dissipation windows 14 are evenly opened on the inner side of the fan frame 1.

The coil is the part that generates a lot of heat during use. The stator 2 can be wrapped by the fixture 3 and then potted with glue. After potting, the PCB and electronic components can be sealed, thereby solving the overall waterproof problem of the fan and greatly improving production efficiency.

The stator slot 12 is centrally located at the top of the main body 11, the limiting protrusion 13 is centrally fixed inside the stator slot 12, and the wire groove 15 is located at the top of the main body 11.

[0025] Four sets of heat dissipation windows 14 are opened through the outer wall of the stator slot 12;

[0026] The stator 2 is installed in the stator slot 12 to fix it to the outer frame 1 of the fan, and the limiting protrusion 13 is installed in the stator 2;

[0027] The stator slot 12 and the limiting protrusion 13 can limit and fix the stator 2, preventing the stator 2 from shaking during assembly;

[0028] The conductors of stator 2 are fixed in conductor groove 15 and pass through the outer casing 11;

[0029] The wire groove 15 can limit the wires of the stator 2, thereby improving the efficiency of assembly.

[0030] The fixture 3 is set on the outside of the stator slot 12, and the four sets of heat dissipation windows 14 are located between the stator 2 and the fixture 3. The fixture 3 seals and wraps the four sets of heat dissipation windows 14.

[0031] During production, the stator 2 can be inserted and fixed in the stator slot 12. The lower end of the stator 2 is wrapped with the jig 3, and then AB glue is poured in for fixation. AB glue itself has a strong heat dissipation effect and can also play a waterproof role, preventing the internal electronic components from being damaged by moisture.
