Description

Technical Field

[0001] This utility model relates to the field of vortex fan technology, specifically a water-cooled vortex fan. Background Technology

[0002] Vortex blowers, as high-efficiency gas conveying devices, are widely used in wastewater treatment, vacuum adsorption, and industrial conveying. In actual operation, vortex blowers typically require continuous operation for extended periods. The motor and blower generate significant heat during high-speed operation. If heat dissipation is insufficient, the motor temperature will become excessively high, insulation performance will deteriorate, and there is even a risk of motor burnout, severely impacting the blower's stability and lifespan.

[0003] The common cooling methods for vortex fans are mainly as follows: One method relies on air-cooled heat sinks mounted on the motor casing to achieve natural heat dissipation through air convection. However, this method is less effective in high-temperature or enclosed environments and often cannot meet the requirements for continuous operation.

[0004] Another method is forced air cooling, which uses an independent fan outside the motor to accelerate airflow and remove heat. While this method can improve heat dissipation to some extent, it still depends on the ambient air temperature and flow. When the ambient temperature is too high, the cooling effect decreases significantly. Some technologies attempt to add a metal heat shield or water-cooled jacket between the motor and the fan to slow down heat transfer. However, these structures typically only achieve passive cooling with limited efficiency. Furthermore, if the water-cooled jacket relies solely on natural convection circulation, the coolant temperature is difficult to lower in time, leading to a decline in heat dissipation over long-term operation.

[0005] In summary, existing vortex blowers generally suffer from low heat dissipation efficiency, motor overheating, and a single, unstable cooling method. Especially under high-temperature or long-term operating conditions, they cannot guarantee the stability and reliability of the equipment. Therefore, there is an urgent need for a new vortex blower cooling structure that can significantly improve overall heat dissipation capacity through a combination of efficient liquid cooling circulation and active cooling, and achieve intelligent temperature control, thereby ensuring the blower's continuous and stable operation under extreme conditions. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a water-cooled vortex fan, including a fan, a motor, a liquid storage box, and a circulating pump assembly. A heat dissipation fin is installed on the top surface of the liquid storage box, and a semiconductor cooling chip is attached to the bottom surface of the heat dissipation fin. The cooling surface of the semiconductor cooling chip faces the inside of the liquid storage box, actively cooling the water-cooled liquid inside the box, while its heating surface exchanges heat with the external environment through the heat dissipation fin.

[0008] A heat-conducting ring is provided between the motor and the fan. The top of the heat-conducting ring is connected to a heat-conducting coil located inside the liquid storage box. The coil is filled with heat-conducting liquid to quickly conduct the heat generated at the contact surface between the motor and the fan to the inside of the liquid storage box, thereby achieving efficient heat dissipation.

[0009] The bottom of the liquid storage box is connected to a circulating liquid pipe, which is arranged around the outside of the motor. One end of the circulating liquid pipe is connected to the circulating pump assembly, and the other end returns to the liquid storage box through a return pipe, thus forming a liquid-cooled circulation loop. The circulating pump assembly includes a pump box, a rotor, and a vane. The rotor is connected to the motor output shaft and drives the vane to slide within the pump box, pushing the coolant between the circulating liquid pipe and the liquid storage box to form a stable circulation, carrying away the heat from the outer wall of the motor.

[0010] In a preferred example, the motor adopts a dual-output structure, with one output shaft driving the fan and the other output shaft driving the circulating pump group to rotate, thereby realizing the synchronous operation of the fan and the cooling system.

[0011] In a preferred example, the inner center of the pump box is offset from the axis of the impeller and close to one end of the return pipe, and the connection between the return pipe and the circulating liquid pipe is symmetrically arranged with respect to the center of the pump box, thereby improving the liquid flow efficiency and circulation stability.

[0012] In a preferred example, a temperature sensor is installed on the surface of the liquid storage box and is electrically connected to the thermostat, which can detect the temperature of the coolant in real time and adjust the working status of the circulating pump group, thereby achieving intelligent temperature control and preventing the motor from overheating.

[0013] In summary, this utility model, through its composite cooling design of "liquid cooling circulation + semiconductor refrigeration + heat transfer through a heat-conducting ring," not only significantly improves the heat dissipation effect of the vortex fan under high-temperature conditions and effectively reduces the motor operating temperature, but also achieves automatic adjustment through temperature sensing and constant temperature control, ensuring the long-term stability and reliability of the fan.

[0014] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting a heat-conducting ring and heat-conducting coil between the motor and the fan, and combining them with the circulating liquid pipe, circulating pump group and liquid storage box to form a liquid-cooled circulation loop, the heat generated by the motor and fan during operation can be effectively removed, avoiding overheating of the motor due to long-term operation, and significantly improving the heat dissipation efficiency and operational stability of the fan in high-temperature environments.

[0015] 2. In this invention, a semiconductor cooling chip is installed below the heat dissipation fins of the liquid storage box. Its cooling surface directly acts on the coolant within the storage box, achieving active cooling of the liquid. Simultaneously, the heating surface dissipates heat efficiently through the heat dissipation fins, thus forming a composite cooling method of "liquid cooling + semiconductor cooling." This design not only enhances the heat dissipation effect but also, in conjunction with a temperature sensor and a constant temperature controller, enables intelligent temperature regulation, ensuring the long-term stable operation and service life of the vortex fan.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a water-cooled vortex fan.

[0021] Combination Figures 1-5 As shown, the present invention provides a water-cooled vortex fan, including a fan 100, a motor 110, a liquid storage box 200, a circulating pump set 300, and auxiliary components for heat dissipation and cooling.

[0022] A heat dissipation fin 210 is fixedly installed on the top surface of the liquid storage box 200, and a semiconductor cooling chip 240 is attached to the bottom surface of the heat dissipation fin 210. Its cooling surface faces the inside of the liquid storage box 200 and is used to cool the water coolant inside the liquid storage box 200. Its heating surface dissipates heat to the outside through the heat dissipation fin 210, thereby ensuring the stable operation of the cooling chip 240.

[0023] A heat-conducting ring 220 is fixedly installed between the motor 110 and the fan 100. The top of the heat-conducting ring 220 is connected to a heat-conducting coil 221 located inside the liquid storage box 200, and the coil is filled with heat-conducting fluid. This structure can quickly conduct the heat generated at the contact surface between the motor 110 and the fan 100 to the coolant inside the liquid storage box 200 during operation, thereby improving the overall heat dissipation efficiency.

[0024] The bottom surface of the liquid storage box 200 is connected to a circulating liquid pipe 230, which is arranged around the outside of the motor 110 and can absorb the heat emitted from the outer wall of the motor 110 during liquid circulation. One end of the circulating liquid pipe 230 is connected to the inside of the circulating pump assembly 300, and the top surface of the circulating pump assembly 300 is provided with a return pipe 301 that communicates with the inner cavity of the liquid storage box 200, thereby forming a complete liquid circulation loop.

[0025] The circulating pump assembly 300 includes a pump housing 310, a rotor 320, and a vane 330. The rotor 320 is coaxially connected to the output end of the motor 110 and is rotatably mounted inside the pump housing 310. The surface of the rotor 320 has several radially arranged grooves 321. The vane 330 is slidably mounted inside the grooves 321, with its two ends abutting against the inner wall of the pump housing 310. When the motor 110 starts, the rotor 320 drives the vane 330 to slide within the grooves 321, propelling the liquid to circulate between the pump housing 310, the circulating liquid pipe 230, the return pipe 301, and the storage tank 200.

[0026] In one embodiment, the motor 110 is a dual-output motor. One output shaft passes through the heat-conducting ring 220 and extends into the fan 100 to drive the fan 100 to work. The other output shaft passes through the pump box 310 to drive the rotor 320 to rotate, thereby realizing the synchronous operation of the fan 100 and the circulating pump group 300.

[0027] In another embodiment, the inner cavity center of the pump box 310 is offset from the axis of the impeller 320 and close to one end of the return pipe 301, and the connection positions of the return pipe 301 and the circulating liquid pipe 230 with the pump box 310 are symmetrically arranged about the center of the pump box 310, thereby improving the flow rate and efficiency of liquid circulation.

[0028] In a further embodiment, a temperature sensor is provided on the surface of the liquid storage box 200, and the signal output terminal of the temperature sensor is electrically connected to the thermostat. The thermostat can automatically control the working state of the circulating pump group 300 according to the temperature change of the liquid in the liquid storage box 200, thereby ensuring that the entire water cooling system operates stably within a preset temperature range.

[0029] Working principle and usage process of this utility model: This utility model's water-cooled vortex fan achieves efficient cooling of the fan 100 and motor 110 through a multi-stage cooling method of circulating liquid cooling, semiconductor refrigeration, and heat-conducting ring-assisted heat dissipation, thereby improving overall operational stability.

[0030] Motor 110 is a dual-output motor, one end drives fan 100 to work, and the other end drives circulating pump 300 to operate. Fan 100 generates the required airflow, and circulating pump 300 drives the circulation of coolant.

[0031] The impeller 320 of the circulating pump unit 300 rotates under the drive of the motor 110, and the vane 330 slides back and forth in the groove 321, pushing the circulating liquid pipe 230 and the coolant in the return pipe 301 to form a closed loop. The liquid flows out from the storage box 200, passes through the circulating liquid pipe 230 around the outer wall of the motor 110 to absorb heat, and then flows back to the storage box 200, completing the liquid circulation heat exchange.

[0032] A heat-conducting ring 220 is provided on the contact surface between the motor 110 and the fan 100. The heat-conducting ring contains a heat-conducting liquid and is connected to the heat-conducting coil 221 in the liquid storage box 200. This can quickly conduct the heat from the operation of the motor and the fan to the liquid storage box 200, thereby improving the heat dissipation efficiency.

[0033] The bottom surface of the heat dissipation fin 210 fixed on the top of the liquid storage box 200 is fitted with a semiconductor cooling chip 240, with its cooling surface facing the inside of the liquid storage box 200 to provide further cooling for the water coolant; the heating surface dissipates heat to the outside through the heat dissipation fin 210 to ensure the efficient operation of the cooling system.

[0034] The surface of the liquid storage box 200 is equipped with a temperature sensor to monitor the temperature of the coolant in real time. The temperature signal is input to the thermostat, which automatically adjusts the working status of the circulating pump group 300 according to the temperature change, thereby maintaining the system in operation within the set temperature range.
