Description

Technical Field

[0001] This application relates to the field of blowers, and more specifically, to a circulating water cooling mechanism for a suspended blower. Background Technology

[0002] As a highly efficient fluid transport device, the core power component of a suspension blower, the motor, generates a significant amount of heat during operation. This is primarily due to a combination of factors, including electromagnetic losses, iron losses, and mechanical losses within the motor.

[0003] Especially in high-power-density suspended blowers, the heat generated per unit volume of the motor is even more significant. If this heat cannot be dissipated in a timely and effective manner, the internal temperature of the motor will rise sharply. High temperatures will accelerate the aging of the internal insulation materials of the motor, shorten the service life of the motor, and even cause the risk of insulation breakdown, threatening operational safety; in addition, the performance and stability of the motor will also be significantly reduced when operating at high temperatures. Utility Model Content

[0004] This application provides a suspended blower circulating water cooling mechanism that can cool the motor and buffer the cooling circulating water.

[0005] Specifically, this application is implemented through the following technical solution: This application provides a circulating water cooling mechanism for a suspended blower, comprising: The motor has an internal cooling chamber, which has a circulating water inlet and a circulating water outlet. A circulating water tank is located below the motor and is connected to the circulating water outlet via a pipe. It is used to receive and temporarily store the circulating water flowing out of the motor. The circulating water tank has a water tank outlet at the bottom. The heat exchanger includes an adjacent circulating pipe and an external pipe. One end of the circulating pipe is connected to the outlet of the water tank, and the other end is connected to the circulating water inlet to form a circulating water loop. The external pipe is used to connect to an external water supply pipe to exchange heat with the circulating water in the circulating pipe. A water pump, connected in the circulating water circuit, is used to provide circulation power.

[0006] Optionally, the interior of the circulating water tank is divided into a first chamber and a second chamber in parallel by a vertical plate arranged along the height direction; the first chamber is connected to the circulating water outlet, and a water outlet is opened at the bottom of the vertical plate to allow the circulating water flowing out of the motor to flow through the first chamber to the second chamber; a cooling fan is provided on the outer wall of the first chamber.

[0007] Optionally, the first chamber is provided with at least two staggered partitions, which are used to extend the flow path of circulating water in the first chamber.

[0008] Optionally, the cooling chamber is arranged around the stator coils inside the motor.

[0009] Optionally, a transparent graduated level gauge for direct observation of the liquid level inside the second chamber is installed on the side wall.

[0010] Optionally, the second chamber is further provided with a drain outlet for discharging circulating water and a water inlet for replenishing circulating water on its side wall.

[0011] Optionally, the width of the first chamber is smaller than the width of the second chamber, the first chamber is used to receive circulating water flowing out of the motor, and the second chamber is used to temporarily store the circulating water.

[0012] Optionally, the cooling fan is mounted on the outer wall of the first chamber via a frame, and a ventilation gap is maintained between the blade plane of the cooling fan and the side wall.

[0014] This application provides a circulating water cooling mechanism for a suspended blower, comprising a motor, a circulating water tank, a heat exchanger, and a water pump. First, circulating water flows through the cooling chamber inside the motor, directly carrying away the heat generated during motor operation, thus achieving efficient water cooling of the motor—this is the basic function of the system. Second, the circulating water tank, located below the motor, is designed to receive and temporarily store the circulating water flowing out of the motor. This design utilizes gravity to facilitate the inflow of high-temperature water into the tank. Simultaneously, the tank's volume provides a buffer space for the system, accommodating circulating water with volume fluctuations due to temperature changes, and aiding in the separation of air bubbles carried in the water, thereby enhancing the stability and reliability of the entire circulation system.

[0019] refer to Figure 1This application provides a circulating water cooling mechanism for a suspended blower, including a motor 100, a circulating water tank 200, a heat exchanger 300, and a water pump 400. The motor 100 has a cooling chamber 110 inside, with a circulating water inlet 111 and a circulating water outlet 112. The circulating water tank 200 is located below the motor 100 and is connected to the circulating water outlet 112 via a pipe, used to receive and temporarily store the circulating water flowing out of the motor 100. The bottom of the circulating water tank 200 has a tank outlet 201. The heat exchanger 300 includes an adjacent circulating pipe 310 and an external pipe 320. One end of the circulating pipe 310 is connected to the tank outlet 201, and the other end is connected to the circulating water inlet 111, forming a circulating water loop. The external pipe 320 is used to connect to an external water supply pipe for heat exchange with the circulating water in the circulating pipe 310. The water pump 400 is connected in the circulating water loop to provide circulation power. The water pump 400 and heat exchanger 300 can be integrated on one side of the circulating water tank 200.

[0020] First, the circulating water flows through the cooling chamber 110 inside the motor 100, directly carrying away the heat generated by the motor 100 during operation, thus achieving efficient water cooling of the motor 100—this is the basic function of the system. Second, the circulating water tank 200, located below the motor 100, is designed to receive and temporarily store the circulating water flowing out of the motor 100. This design utilizes gravity to facilitate the flow of high-temperature water into the tank. Simultaneously, the tank's volume provides a buffer space for the system, accommodating circulating water with volume fluctuations due to temperature changes, and aiding in the separation of air bubbles carried in the water, thereby enhancing the stability and reliability of the entire circulation system.

[0021] In one embodiment, reference Figure 2 and Figure 3 The circulating water tank 200 is internally divided into a first chamber 210 and a second chamber 220 by a vertical plate 202 arranged along the height direction. The first chamber 210 is connected to the circulating water outlet 112. A water outlet 203 is provided at the bottom of the vertical plate 202 to allow the circulating water flowing from the motor 100 to flow through the first chamber 210 to the second chamber 220. A cooling fan 500 is provided on the outer wall of the first chamber 210. The circulating water tank 200 is internally divided into a first chamber 210 and a second chamber 220 by the vertical plate 202. The high-temperature circulating water flowing from the motor 100, after heat exchange, is guided to the first chamber 210, and the cooling fan 500 located on the outer wall of the first chamber 210 can specifically provide forced air cooling for this concentrated high-temperature water. This structure enables a highly efficient pre-cooling mechanism, which dissipates some heat before the high-temperature circulating water enters the main heat exchanger 300, thus helping to reduce the workload of the main heat exchanger 300.

[0022] refer to Figure 3 and Figure 4 In one embodiment, at least two staggered baffles 211 are provided in the first chamber 210, which extend the flow path of the circulating water within the first chamber 210. Specifically, there may be three or more baffles. The staggered baffles 211 in the second chamber 220 directly alter the fluid path. The circulating water is forced to flow along the meandering path guided by the baffles 211, significantly extending its journey within the tank. The longer flow path means more contact time between the circulating water and the tank wall, thereby promoting heat dissipation through the cooling fan 500 and making the cooling process more efficient.

[0023] refer to Figure 6 In one embodiment, a cooling chamber is arranged around the stator coil 120 inside the motor 100. This arrangement provides a precise and efficient cooling method. This tightly enclosed structure allows the circulating water to directly exchange heat with the core heat-generating component, the stator coil 120, ensuring that heat from the main heat source is rapidly dissipated. Simultaneously, this chamber, as a completely independent space isolated from the stator coil 120, effectively prevents circulating water leakage into the motor 100, ensuring the electrical safety of the motor 100.

[0024] refer to Figure 3 A transparent graduated level gauge 230 is installed on the side wall of the second chamber 220 for direct observation of the internal liquid level. Installing the transparent graduated level gauge 230 on the side wall of the second chamber 220 provides an intuitive and convenient monitoring method. Operators can directly observe the scale on the transparent graduated level gauge 230 to understand the real-time level of circulating water in the system, facilitating daily inspection and maintenance, without the need for any tools.

[0025] refer to Figure 7 In one embodiment, the second chamber 220 is further provided with a drain outlet 221 for discharging circulating water and a water inlet 222 for replenishing circulating water on its side wall. The drain outlet 221 and water inlet 222 on the side wall of the second chamber 220 facilitate system maintenance. When the liquid level is insufficient as observed through the transparent graduated level gauge 230, it can be replenished through the water inlet 222; when it is necessary to replace the circulating water or repair the system, the liquid can be completely drained through the drain outlet 221. These two interfaces, together with the transparent graduated level gauge 230, constitute a complete and easy-to-operate maintenance functional unit.

[0026] refer to Figure 3The width of the first chamber 210 is smaller than the width of the second chamber 220. The first chamber 210 is used to receive circulating water flowing from the motor 100, while the second chamber 220 is used to temporarily store the circulating water. Designing the width of the first chamber 210 to be smaller than that of the second chamber 220 achieves functional zoning and optimization within the water tank. The narrow first chamber 210 ensures that high-temperature incoming water flows concentratedly through the heat dissipation area, improving pre-cooling efficiency; while the wide second chamber 220 provides the main liquid storage and buffer volume for temporarily storing the pre-cooled circulating water, ensuring the stability of the system's liquid supply.

[0027] refer to Figure 3 and Figure 5 In one embodiment, the cooling fan 500 is mounted on the outer wall of the first chamber 210 via a frame 510, with a ventilation gap maintained between the blades of the cooling fan 500 and the side wall. This ventilation gap ensures unobstructed cooling airflow. This gap prevents airflow short-circuiting caused by the fan blades being too close to the wall, allowing ambient air to be effectively drawn in and flow across the entire chamber wall surface, thereby improving the cooling effect on the side wall of the first chamber 210 and its internal circulating water.

[0028] In one embodiment, reference Figure 5 The circulating water tank 200 has a raised support frame 600 fixed on top, and the motor 100 has multiple bases 130 at its bottom, each base 130 supporting the support frame 600. The raised support frame 600 fixed on top of the circulating water tank 200 supports the motor 100 bases 130, optimizing the overall structural layout. The support frame 600 provides a stable mounting platform for the motor 100, enhancing the overall structural stability and rigidity of the equipment during operation, while also making the equipment layout more compact and rational.
