Description
Technical Field
[0001] This utility model relates to the field of cooling device technology, specifically a cooling device with a water pump and a fan driven coaxially. Background Technology
[0002] In existing industrial equipment cooling systems, cooling fans and water pumps are typically designed as separate units. Specifically, cooling fans primarily rely on air cooling to cool the heat-generating components of the equipment, while water pumps use circulating pipes to deliver coolant for liquid cooling. This traditional approach requires separate brackets, drive motors, and control modules for each unit, and relies on a complex piping system to connect them to form a complete cooling loop. However, this traditional architecture suffers from several technical bottlenecks: Firstly, the separate layout of cooling fans and water pumps occupies a large amount of space, making compact integration difficult, especially in miniaturized equipment, severely hindering the development of lightweight equipment. Secondly, the independent drive of dual motors significantly increases the overall energy consumption of the system. Furthermore, long-distance pipe connections not only cause coolant pressure loss and reduce heat exchange efficiency but also increase the risk of leakage due to the increased number of sealing joints. At the same time, the decentralized structure complicates daily maintenance and repair processes, further increasing operation and maintenance costs. Utility Model Content

[0026] Example 1
[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a cooling device coaxially driven by a water pump and a fan, including a dual-shaft motor 1 and a water pump head 2. The dual-shaft motor 1 is located on the left side of the water pump head 2. The first output end of the dual-shaft motor 1 passes through the water pump head 2 and is connected to the impeller inside the water pump head 2 through a coupling.
[0028] The heat dissipation mechanism 3 includes a fan impeller 31, which is fixedly installed on the surface of the second output end of the dual-shaft motor 1. The input end of the water pump head 2 is connected to the liquid inlet pipe 32. An annular microchannel 33 is provided on the outside of the dual-shaft motor 1. The annular microchannel 33 is arranged in an annular honeycomb shape. The output end of the water pump head 2 is connected to the right side of the annular microchannel 33 through a pipe. An adjustment component 34 is connected to the left side of the annular microchannel 33.
[0029] Protective mechanism 4 is located on the outside of the fan impeller 31 and the water pump head 2.
[0030] Specifically, by utilizing the heat dissipation mechanism 3, after the dual-shaft motor 1 is started, the two output ends of the dual-shaft motor 1 can drive the impeller 31 of the fan and the impeller inside the water pump head 2 to rotate respectively, thereby driving the impeller 31 of the fan and the impeller inside the water pump head 2 to rotate simultaneously, which can reduce energy consumption.
[0031] Furthermore, after connecting the inlet pipe 32 to the container storing coolant, starting the dual-axis motor 1 enables the first output end of the dual-axis motor 1 to drive the impeller inside the water pump head 2 to rotate, thereby generating a negative pressure inside the water pump head 2 to draw coolant into the water pump head 2 and send it into the annular microchannel 33 through the pipe. At the same time, the second output end of the dual-axis motor 1 can drive the fan impeller 31 to rotate, so that the wind generated by the fan impeller 31 is blown to the outside through the annular microchannel 33 to form a cooling wind.
[0032] Example 2
[0033] In the second embodiment of this utility model, the adjustment component 34 includes an outlet pipe 341, a first housing 342 is provided on the outside of the dual-axis motor 1, the surface of the annular microchannel 33 is fixedly connected to the inner wall of the first housing 342, one end of the outlet pipe 341 away from the annular microchannel 33 passes through the first housing 342 and extends to the top of the first housing 342, a water temperature sensor 343 is fixedly installed on the surface of the outlet pipe 341, a mounting base 344 is fixedly connected to the top of the surface of the first housing 342, a frequency converter 345 is fixedly installed on the bottom of the inner wall of the mounting base 344, the water temperature sensor 343 is electrically connected to the frequency converter 345 through a wire, and the frequency converter 345 is electrically connected to the dual-axis motor 1 through a wire.
[0034] Specifically, the adjustment component 34 can be used to position the annular microchannel 33, and at the same time facilitates the automatic adjustment of the speed of the two output ends of the dual-axis motor 1.
[0035] Furthermore, the coolant entering the annular microchannel 33 can be discharged through the outlet pipe 341 after overflowing. At this time, the water temperature sensor 343, which is connected to the outlet pipe 341, can detect the temperature of the coolant in real time and transmit the signal to the frequency converter 345. When the detected temperature is higher than the set temperature of the frequency converter 345, the frequency converter 345 automatically increases the speed of the dual-axis motor 1, which can further improve the heat exchange efficiency. When the detected temperature is lower than the set temperature of the frequency converter 345, the frequency converter 345 automatically reduces the speed of the dual-axis motor 1, thereby achieving energy saving.
[0036] Example 3
[0037] In the third embodiment of this utility model, the protective mechanism 4 includes a second housing 41, the right side of which is fixedly connected to the left side of the first housing 342. A fixing plate 42 is provided on the left side of the fan impeller 31. The second output end of the dual-shaft motor 1 is movably connected to the right side of the fixing plate 42 through a bearing. A first mesh cover 43 is fixedly connected to the surface of the fixing plate 42. The right side of the first mesh cover 43 is fixedly connected to the left side of the second housing 41. A second mesh cover 44 is fixedly connected to the right side of the second housing 41 through a flange.
[0038] Specifically, the protective mechanism 4 can protect the fan impeller 31, the dual-shaft motor 1 and the water pump head 2, while also facilitating air circulation.
[0039] Furthermore, the first housing 342, the second housing 41, the fixing plate 42, the first mesh cover 43 and the second mesh cover 44 can shield and protect the fan impeller 31, the dual-shaft motor 1 and the water pump head 2. At the same time, the first mesh cover 43 and the second mesh cover 44 facilitate the rotation of the fan impeller 31 to generate wind and blow it to the right side of the water pump head 2.
[0040] Working principle:
[0041] First, the entire device is installed on one side of the cooling core using the mounting base 10. Since the first output end of the dual-axis motor 1 is connected to the impeller inside the water pump head 2 via a reducer, and the second output end of the dual-axis motor 1 is fixedly equipped with a fan impeller 31, after connecting the inlet pipe 32 to an external container storing coolant, starting the dual-axis motor 1 causes the first output end of the motor 1 to rotate, creating a negative pressure inside the water pump head 2 to draw coolant into the water pump head 2 and send it through the pipe into the annular microchannel 33. At this time, the arc-shaped baffle 11 prevents the coolant from directly flowing to the outlet pipe 341. Simultaneously, the second output end of the dual-axis motor 1 drives the fan impeller 31 to rotate, causing the airflow generated by the fan impeller 31 to blow outwards through the annular microchannel 33, forming cooling air that exchanges heat with the surface of the heat dissipation core, achieving a cooling effect. When the coolant inside the annular microchannel 33 overflows... The coolant can be discharged through the outlet pipe 341. At this time, the water temperature sensor 343, which is connected to the outlet pipe 341, can detect the temperature of the coolant in real time and transmit the signal to the frequency converter 345. When the detected temperature is higher than the set temperature of the frequency converter 345, the frequency converter 345 automatically increases the speed of the dual-axis motor 1, which can further improve the heat exchange efficiency. When the detected temperature is lower than the set temperature of the frequency converter 345, the frequency converter 345 automatically reduces the speed of the dual-axis motor 1, thereby achieving energy saving. The first housing 342, the second housing 41, the fixing plate 42, the first mesh cover 43 and the second mesh cover 44 can shield and protect the fan impeller 31, the dual-axis motor 1 and the water pump head 2. The fixing ring 5, the support ring 7 and the support rod 8 can provide stable support for the dual-axis motor 1 and the water pump head 2. At the same time, through the lightweight housing design, the overall weight is reduced compared with the split combination, and the installation space occupied is reduced.
[0042] In summary: By setting up the heat dissipation mechanism 3 and starting the dual-axis motor 1, the coolant can easily pass through the inlet pipe 32 into the annular microchannel 33. At the same time, the rotation of the fan impeller 31 can blow out the cold air emitted from the surface of the annular microchannel 33, achieving a cooling effect. This solves two problems: First, the separate layout of the cooling fan and water pump occupies a lot of space, which is difficult to achieve compact integration, especially in miniaturized equipment, and seriously restricts the development of lightweight equipment. Second, the independent drive of the dual motors leads to a significant increase in the overall energy consumption of the system. In addition, the long-distance pipeline connection not only causes pressure loss of coolant and reduces heat exchange efficiency, but also brings a higher risk of leakage due to the increase in sealing joints. At the same time, the decentralized structure complicates the daily maintenance and repair process, further increasing the operation and maintenance costs. This achieves the effect of improving heat exchange efficiency and reducing energy consumption.
