DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1-Figure 5 An embodiment of the present application provides a low-noise fan, including a fan part 10, a sound insulation component 20 and a heat dissipation component 30.

[0028] Among them, the fan part 10 can install the fan and generate and transport a large flow of gas. The sound insulation component 20 can silence the fan to prevent the noise generated by the fan during operation from spreading to the environment and affecting the surrounding environment. The heat dissipation component 30 can dissipate the heat of the motor 120 to prevent the poor heat dissipation effect of the fan due to the setting of the sound insulation component 20, thereby affecting the life of the fan.

[0029] See also Figure 1 , Figure 2 and Figure 3 The fan part 10 includes a base 110 and a motor 120. The outer side of the motor 120 is provided with heat dissipation fins 170 in a circular array. The motor 120 is installed on the base 110. The output end of the motor 120 is connected to the fan housing 130. The fan housing 130 is connected with an air inlet 140 and an air outlet 150. A deflector is installed inside the fan housing 130, and the deflector is connected to the output end of the motor 120. When running, the motor 120 is started to make the deflector run, so that the air volume is introduced through the air inlet 140 and discharged through the air outlet 150. The heat dissipation fins 170 can dissipate heat from the motor 120.

[0030] In this embodiment, a filter 160 is disposed inside the air inlet 140. The filter 160 can filter the air introduced by the air inlet 140 to prevent dust and impurities from entering.

[0031] See also Figure 1 and Figure 2 The sound insulation assembly 20 includes a sound insulation box 210, and the side wall of the sound insulation box 210 is provided with an installation port that matches the air inlet 140 and the air outlet 150; the base 110 is arranged inside the sound insulation box 210, and the sound insulation box 210 is equipped with an inspection door 220, and the air inlet 140 and the air outlet 150 extend to the outside of the sound insulation box 210 through two installation ports respectively, which is convenient for connection with other connecting pipes, and a sealing gasket is arranged at the installation port, so as to block the gap between the installation port and the air inlet 140 and the air outlet 150, thereby improving the sealing effect; wherein, when the ventilator is running, a closed space is formed by the sound insulation box 210 and the inspection door 220, so as to block the noise generated by the ventilator, prevent the noise from spreading to the environment, and improve the comfort of the surrounding environment. Through the inspection door 220, the ventilator can be easily inspected and maintained.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The heat dissipation end of the heat dissipation assembly 30 is arranged outside the motor 120. The heat dissipation assembly 30 includes a heat dissipation sleeve 310 and a water tank 320. The heat dissipation sleeve 310 is detachably mounted outside the motor 120. A water cooling cavity 311 is provided inside the heat dissipation sleeve 310. The water tank 320 is installed on the top of the sound insulation box 210. A connecting piece is connected between the water cooling cavity 311 and the water tank 320. The inner wall of the heat dissipation sleeve 310 is provided with a clearance groove 350 that matches each heat dissipation fin 170, and the clearance groove 350 extends to the inside of the water cooling cavity 311. The connecting part includes a water pump 360, which is installed inside the water tank 320. The water outlet end of the water tank 320 is connected with a water outlet pipe 330, which seals and penetrates the side wall of the water tank 320 and the side wall of the soundproof box 210 and is connected to the bottom of the water cooling chamber 311. The top of the water cooling chamber 311 is connected with a return pipe 340, and the other end of the return pipe 340 seals and penetrates the side wall of the soundproof box 210 and extends to the inside of the water tank 320. A heat dissipation fan 370 is installed on the top of the water tank 320. A mounting plate is fixedly connected to the bottom of the heat dissipation sleeve 310. Among them, when the fan is blocked by the soundproof box 210 and the inspection door 220 to form a cavity, the heat dissipation effect of the motor 120 will be poor during operation. At this time, the heat dissipation sleeve 310 is slidably sleeved on the outside of the motor 120, and then the heat dissipation sleeve 310 is fixed to the base 110 using the mounting plate, and then the water tank 320 is filled with water, and the water pump 360 is started. The water pump 360 pumps the water from the water tank 320 and transports it to the inside of the water cooling chamber 311 through the water outlet pipe 330. When the inside of the water cooling chamber 311 is filled with water, the excess water will flow back to the inside of the water tank 320 through the return pipe 340, so as to realize water circulation to cool down and dissipate heat for the motor 120. Through the arrangement of the heat dissipation sleeve 310, the water tank 320 and the water pump 360, the fan can still dissipate heat for the motor 120 even though it is in a closed space, thereby improving the heat dissipation effect of the motor 120 and thus improving the service life of the fan. By providing the recess 350, each heat dissipating fin 170 can extend into the water cooling chamber 311, thereby increasing the contact area between the heat dissipating fin 170 and water, thereby increasing the heat dissipation effect of the motor 120. By providing the heat dissipating fan 370, the water inside the water tank 320 can be cooled, so that the water inside the water tank 320 will not be too hot due to circulation and cannot be cooled by itself.

[0033] The working principle of the low-noise fan is as follows: when in operation, the motor 120 is started to operate the deflector, so that the air volume is introduced through the air inlet 140 and discharged through the air outlet 150, and the heat dissipation fins 170 can dissipate heat for the motor 120. When the fan is in operation, a closed space is formed by the soundproof box 210 and the inspection door 220, so that the noise generated by the fan can be blocked, the noise is prevented from spreading to the environment, and the comfort of the surrounding environment is improved. Through the inspection door 220, the fan can be easily inspected and maintained. Through the arrangement of the heat dissipation sleeve 310, the water tank 320 and the water pump 360, the fan can still dissipate heat for the motor 120 although it is in a closed space, improve the heat dissipation effect of the motor 120, and thus improve the service life of the fan. Through the arrangement of the give way slot 350, each heat dissipation fin 170 can extend to the inside of the water cooling chamber 311, increase the contact area between the heat dissipation fin 170 and the water, and thus increase the heat dissipation effect of the motor 120. By disposing the heat dissipation fan 370, the water inside the water tank 320 can be cooled, so that the water inside the water tank 320 will not be too hot due to circulation and cannot dissipate heat itself.
