[0024] The utility model will be described further below in combination with specific embodiments:
[0025] This utility model provides a water-cooled heat dissipation structure for a fan, such as Figure 1 , 2 As shown, the fan includes a fan frame 1 and a fan body 3 mounted on the fan frame 1. A condenser 2 is installed in the fan frame 1. The fan body 3 includes a drive motor 4 and a pump body 5. The drive motor 4 has a housing 41, and a rotor and stator are installed inside the housing 41 to drive the fan impeller to generate high-pressure airflow. To solve the problem of heat accumulation generated by the drive motor 4 during long-term operation, a circulation channel is formed in the housing 41. The condenser 2 is connected to the circulation channel and is used to deliver cooling water to the circulation channel to effectively cool the housing 41.
[0026] Specifically, the wind turbine outer frame 1 in this application is a closed shell formed by metal plates. For ease of explanation, this application uses... Figure 1 The image shows the disassembled side panel of the enclosed housing. A mounting bracket 13 is provided on one side metal plate of the fan frame 1, through which the drive motor 4 is fixed. The pump body 5 on one side of the drive motor 4 has an air intake 52 and an air outlet 51. The air intake 52 is located inside the fan frame 1, while the air outlet 51 passes through the side panel of the fan frame 1 and communicates with the outside. It should be noted that the fan frame 1 in this application is provided with an exhaust port 11, through which the air intake 52 of the pump body 5 can draw air, which is then discharged from the air outlet 51.
[0027] Furthermore, a fixing component is provided on the exhaust vent 11, and the condenser 2 is installed through the fixing component; for example... Figure 1 As shown, the condenser 2 is fixed on the exhaust port 11. The fixing component in this application includes several legs 12 set on the exhaust port 11. There are four legs 12, which are respectively set on the four corners of the inner side of the exhaust port 11. A grid is provided on the outer side of the exhaust port 11 for filtration. The legs 12 are L-shaped, and the condenser 2 is clamped in the legs 12 for fixing, so that the condenser 2 can directly exchange heat with the outside air through the exhaust port 11, thereby improving the cooling efficiency.
[0028] Further, the shell 41 is in a whole annular structure, and both ends of the shell 41 are respectively provided with an end cover 412. The end cover 412 comprises a connecting base plate 4121 and a closing plate 4122. The connecting base plate 4121 is installed at both ends of the annular shell 411 along the axial direction, and is used to form a closed cavity which is in communication with the inside of the shell 41. A plurality of serpentine grooves 4123 are formed on the axial surface of the connecting base plate 4121, and the serpentine grooves 4123 are arranged in a bending manner along the annular direction to form a flow path of the cooling water. An inlet 4124 and an outlet 4125 are respectively formed on the radial surface of the connecting base plate 4121 and are in communication with the serpentine grooves 4123. The cooling water enters the serpentine grooves 4123 through the inlet 4124, flows in the serpentine grooves 4123 to absorb heat, and then flows out of the serpentine grooves 4123 through the outlet 4125. The closing plate 4122 is fixedly installed on the outside of the connecting base plate 4121, and is used to close the opening of the serpentine grooves 4123 to form a closed serpentine flow channel 413.
[0029] Reference Figure 3 4 In a specific structure, a plurality of connecting portions 4126 are arranged on the outer edge of the connecting base plate 4121 and are arranged at intervals along the circumference. A connecting hole 4127 is arranged in each connecting portion 4126, and is used to be connected to the end surface of the annular shell 411. In assembly, a fastener, preferably a bolt or an internal hexagonal screw, is arranged in the connecting hole 4127, and passes through the connecting base plate 4121 and the mounting hole of the annular shell 411 to realize mechanical fixation. After the fastener is tightened, a stable and reliable sealing joint surface is formed between the connecting base plate 4121 and the annular shell 411 to form an inner cavity for mounting the rotor and the stator. At the same time, the closing plate 4122 is fixed to the outside of the connecting base plate 4121 by welding or threaded fastening, which further enhances the overall strength and sealing performance of the flow channel structure.
[0030] The annular shell 411 can be made of aluminum alloy or stainless steel to balance the strength and heat conduction performance. The circulating cooling water in the condenser 2 is connected to the serpentine flow channel 413 through a pipeline, and the cooling water circulates in the serpentine flow channel 413 during operation to realize water circulation cooling. Therefore, the driving motor 4 and the pump body 5 can still maintain a good heat dissipation state under high load continuous operation, and have the advantages of high heat dissipation efficiency, compact structure, convenient assembly and high reliability.
[0031] In another embodiment, the annular shell 411 is provided with the end cover 412 at both ends, and the serpentine flow channels 413 in the two end covers 412 are respectively connected to the condenser 2 through pipelines. The synchronous heat dissipation of the end covers 412 at both sides of the annular shell 411 is realized, and the heat dissipation efficiency is further increased.
