Description

Technical Field

[0001] This utility model relates to the field of heat exchange system technology, and more specifically, to a heat exchange system and a motor driver testing device. Background Technology

[0002] With the rapid development of technology, electrical equipment is increasingly used in various industries, and its performance and functions are constantly improving. This has led to a significant increase in the heat generated during operation. Excessive heat not only affects the normal operation of equipment but may also cause malfunctions and shorten its lifespan. To ensure stable operation, effective heat dissipation and cooling measures are needed to protect the equipment.

[0003] Air-cooled heat exchangers, as a common heat dissipation device, primarily utilize air as a cooling medium to remove heat. Their simple structure and ease of maintenance make them widely used for heat dissipation in electrical equipment. However, due to the low thermal conductivity of air, the transfer of heat from the hot surfaces of electrical components to the air is slow, affecting heat dissipation efficiency.

[0004] The problem this invention addresses is how to improve the heat dissipation efficiency of a motor driver testing device.

[0005] To address the aforementioned problems, this utility model provides a heat exchange system and a test device for a motor driver.

[0006] In a first aspect, this utility model provides a heat exchanger applied to a motor driver testing device.

The inlet of the water-cooled heat exchanger is connected to the inlet pipe, and the outlet of the water-cooled heat exchanger is connected to the outlet pipe. The inlet of the fan-water heat exchanger is connected to the inlet pipe, and the outlet of the fan-water heat exchanger is connected to the outlet pipe. The water treatment device is disposed outside the motor driver testing device, and the outlet of the water treatment device is connected to the inlet pipe. The inlet of the water treatment device is connected to the outlet pipe. Each power module is provided with a water-cooled heat exchanger, and each magnetic device is provided with a fan-water heat exchanger.

[0007] Optionally, the water-cooled heat exchanger includes a first water-cooled plate and a second water-cooled plate, wherein the inlet of the first water-cooled plate is connected to the inlet pipe, the outlet of the first water-cooled plate is connected to the outlet pipe, the inlet of the second water-cooled plate is connected to the inlet pipe, and the outlet of the second water-cooled plate is connected to the outlet pipe.

[0008] Optionally, the water-cooled heat exchanger includes a first water-cooled plate and a second water-cooled plate, the inlet of the first water-cooled plate is connected to the inlet pipe, the outlet of the first water-cooled plate is connected to the inlet of the second water-cooled plate, and the outlet of the second water-cooled plate is connected to the outlet pipe.

[0009] Optionally, the air-water heat exchanger includes an air-water heat exchanger shell, a heat exchange tube bundle, and a fan. The heat exchange tube bundle is disposed inside the heat exchanger shell. The water inlet of the heat exchange tube bundle is connected to the water inlet pipe, and the water outlet of the heat exchange tube bundle is connected to the water outlet pipe. A vent is provided on one side of the air-water heat exchanger shell, and the fan is installed on the vent. An air inlet is provided on the side of the air-water heat exchanger shell away from the vent.

[0010] Optionally, the heat exchange system further includes an inlet valve, which is located at one end of the inlet pipe outside the motor driver test device, and is used to regulate the flow rate in the inlet pipe.

[0011] Optionally, the heat exchange system further includes a pressure gauge disposed at one end of the inlet pipe near the inlet valve, the pressure gauge being used to monitor the pressure in the inlet pipe.

[0012] Optionally, the heat exchange system further includes an outlet valve, which is located at one end of the outlet pipe outside the motor driver test device, and is used to regulate the flow rate in the outlet pipe.

[0013] Optionally, the flow meter of the heat exchange system is located at one end of the outlet pipe near the outlet valve, and the flow meter is used to monitor the flow rate in the outlet pipe.

[0014] Optionally, the heat exchange system further includes an air inlet valve located at the end of the water inlet pipe, the air inlet valve being used to expel air from the water inlet pipe.

[0015] Secondly, this utility model provides a motor driver testing device, including at least one heat exchange system as described above.

[0016] The beneficial effects of the heat exchange system of this utility model are as follows: Low-temperature water from the water treatment equipment located outside the motor driver test device is introduced through the inlet pipe and distributed to the water-cooled heat exchanger and the air-water heat exchanger connected to it. The water-cooled heat exchanger on each power module absorbs heat, maintaining the power module at a suitable temperature and ensuring the stability of its operation. Simultaneously, the air-water heat exchanger near each magnetic component dissipates heat and cools the magnetic components, preventing excessively high temperatures around them and ensuring they operate at a suitable temperature, thus guaranteeing their stability. After the low-temperature water flowing through the water-cooled and air-water heat exchangers absorbs heat and transforms into high-temperature water, it is discharged from the inside of the motor driver test device through the outlet pipe to the external water treatment equipment. Thus, the water-cooled and air-water heat exchangers quickly absorb and transfer the heat generated by the power modules and magnetic components inside the motor driver test device, improving the heat dissipation efficiency and preventing performance degradation caused by prolonged exposure to high temperatures, ensuring the safety and stability of its operation. Simultaneously, by adjusting the water temperature in the inlet pipe, the internal temperature of the motor driver testing device can be controlled within a relatively stable range suitable for the operation of electrical components. This helps maintain stable performance parameters of the electrical components, thereby ensuring the overall stable operation of the motor driver testing device and reducing malfunctions and false alarms caused by temperature changes. Furthermore, since the heat exchange system exchanges heat with the outside through the inlet and outlet pipes, there is no need to create ventilation holes in the motor driver testing device. This allows for better sealing and protection, thus better ensuring the stability of the internal components' operation. Attached Figure Description

[0024] In related technologies, during the operation of motor driver testing devices, internal electrical components inevitably generate heat. Air cooling is typically used to dissipate heat, relying primarily on fans to exchange air between the inside and outside of the device, thus removing heat. However, air has relatively low thermal conductivity. Compared to specialized heat dissipation media (such as water and coolant), air has a lower specific heat capacity, causing its temperature to rise faster when absorbing the same amount of heat, and its heat transfer rate is slower, resulting in lower heat exchange efficiency. This means that in air-cooled systems, a large airflow and a long cooling time are required to achieve a good cooling effect. When electrical components have high power and generate significant heat, air cooling may not be able to dissipate the heat effectively and promptly, causing the internal temperature of the device to continue to rise and affecting the normal operation of the electrical components. For example, power modules and magnetic devices (such as transformers and inductors) generate a large amount of heat during operation. If relying solely on air cooling, under high external environmental temperatures or high equipment loads, insufficient heat dissipation can easily lead to equipment failure or damage. Furthermore, the airflow and exchange can also bring many adverse effects. When external air enters the motor driver test device, a large amount of dust particles and other impurities in the external environment will enter with the air. Dust has a certain degree of conductivity or may adsorb moisture. Once it adheres to the surface of electrical components, it may gradually accumulate and form a dirt layer. For power components, dust may interfere with their heat dissipation channels, reduce the heat dissipation effect, and thus cause the components to overheat and degrade or even be damaged, thereby affecting the stability of the motor driver test device.

[0025] To address the problems existing in the aforementioned related technologies, this utility model provides a heat exchange system and a test device for a motor driver.

[0026] like Figure 1 As shown in the figure, a heat exchange system provided by this utility model embodiment is applied to a motor driver testing device. The motor driver testing device includes a power module and magnetic devices. The heat exchange system includes an inlet pipe, an outlet pipe, a water-cooled heat exchanger, a fan-water heat exchanger, and a water treatment device. The inlet of the water-cooled heat exchanger is connected to the inlet pipe, and the outlet of the water-cooled heat exchanger is connected to the outlet pipe. The inlet of the fan-water heat exchanger is connected to the inlet pipe, and the outlet of the fan-water heat exchanger is connected to the outlet pipe. The water treatment device is located outside the motor driver testing device, and the outlet of the water treatment device is connected to the inlet pipe. The inlet of the water treatment device is connected to the outlet pipe. Each power module is provided with a water-cooled heat exchanger, and each magnetic device is provided with a fan-water heat exchanger.

[0027] Specifically, the heat exchange system includes a water-cooled heat exchanger and a fan-water heat exchanger installed inside the motor driver testing device, and a water treatment device installed outside the motor driver testing device. The water-cooled heat exchanger and the fan-water heat exchanger are connected to the water treatment device via inlet and outlet pipes, allowing the heat exchange medium (water) to circulate within the system. The water treatment device cools the high-temperature water flowing into the outlet pipe, generating low-temperature water, which is then introduced into the connected inlet pipe through the outlet. The low-temperature water is then distributed to the water-cooled heat exchanger and the fan-water heat exchanger located inside the motor driver testing device, thereby enabling… The system uses a water-cooled heat exchanger to dissipate heat from the power module and a fan-cooled heat exchanger to dissipate heat from the magnetic components. Furthermore, through outlet pipes connected to the outlets of both the water-cooled and fan-cooled heat exchangers, the high-temperature water, converted from heat absorption in these exchangers, is discharged to a water treatment device located outside the motor driver testing device. The water treatment device cools the high-temperature water, converting it back into low-temperature water, which is then used to dissipate heat from the components inside the motor driver testing device. This achieves the recycling of the cooling medium (water) in the heat exchange system, reducing water consumption and improving water utilization efficiency. By connecting the inlets of the water-cooled heat exchanger and the air-water heat exchanger to the inlet pipe, and the outlets of the water-cooled heat exchanger and the air-water heat exchanger to the outlet pipe, the water-cooled heat exchanger and the air-water heat exchanger are connected in parallel between the inlet pipe and the outlet pipe. Compared with the series connection, this avoids mutual interference between the water-cooled heat exchanger and the air-water heat exchanger, and improves the heat dissipation effect of the water-cooled heat exchanger and the air-water heat exchanger.

[0028] Furthermore, the power modules in the motor drive testing device can be cooled using water-cooled heat exchangers, while magnetic components such as transformers and inductors can be cooled using air-cooled heat exchangers. The number of water-cooled and air-cooled heat exchangers can be determined based on the number of power modules and magnetic components in the motor drive testing device, as well as their heat generation. One water-cooled heat exchanger is installed on each power module, and a corresponding air-cooled heat exchanger is installed near each magnetic component. When there are n sets of power modules and corresponding magnetic components in the motor drive testing device, n sets of water-cooled and air-cooled heat exchangers are installed in parallel. After the low-temperature water absorbs heat in the water-cooled and air-cooled heat exchangers, its temperature rises and it becomes high-temperature water. This high-temperature water flows into a connected outlet pipe through its respective outlet, and then is discharged through the outlet pipe to a water treatment device located outside the motor drive testing device. By using inlet and outlet pipes, as well as external water treatment equipment, the heat generated by the power and magnetic components inside the motor driver test device is transferred to the outside, thus achieving heat dissipation and cooling of the internal components. The heat exchange system only needs to exchange and transfer the internal temperature of the motor driver test device through the inlet and outlet pipes. This avoids the need to use the temperature difference between the inside and outside air to cool the internal components by opening ventilation openings, improving the sealing effect and protection level of the device. For example, in cases with high sealing requirements, the protection level of the motor driver test device can meet IP21. Furthermore, since there is no airflow between the inside and outside of the device, it avoids the influence of external dust or particulate matter on the internal electrical components of the motor driver test device, ensuring the safety and stability of the motor driver test device's operation.

[0029] In this embodiment, low-temperature water from a water treatment device located outside the motor driver testing device is introduced through an inlet pipe and distributed to the connected water-cooled heat exchanger and air-water heat exchanger. The water-cooled heat exchanger on each power module absorbs heat, maintaining the power module at a suitable temperature and ensuring stable operation. Simultaneously, the air-water heat exchanger near each magnetic component dissipates heat, preventing excessively high temperatures around the magnetic components and ensuring they operate at a suitable temperature, thus guaranteeing stable operation. After the low-temperature water flowing through the water-cooled and air-water heat exchangers absorbs heat and transforms into high-temperature water, it is discharged from the inside of the motor driver testing device through an outlet pipe to the external water treatment device. This allows for the rapid absorption and transfer of heat generated by the power modules and magnetic components inside the motor driver testing device, improving heat dissipation efficiency and preventing performance degradation due to prolonged exposure to high temperatures, thus ensuring safe and stable operation. Simultaneously, by adjusting the water temperature in the inlet pipe, the internal temperature of the motor driver testing device can be controlled within a relatively stable range suitable for the operation of electrical components. This helps maintain stable performance parameters of the electrical components, thereby ensuring the overall stable operation of the motor driver testing device and reducing malfunctions and false alarms caused by temperature changes. Furthermore, since the heat exchange system exchanges heat with the outside through the inlet and outlet pipes, there is no need to create ventilation holes in the motor driver testing device. This allows for better sealing and protection, thus better ensuring the stability of the internal components' operation.

[0030] Optionally, combined Figure 1 and Figure 2 As shown, the water-cooled heat exchanger includes a first water-cooled plate and a second water-cooled plate. The inlet of the first water-cooled plate is connected to the inlet pipe, the outlet of the first water-cooled plate is connected to the outlet pipe, the inlet of the second water-cooled plate is connected to the inlet pipe, and the outlet of the second water-cooled plate is connected to the outlet pipe.

[0031] Specifically, the water-cooled heat exchanger includes a first water-cooled plate and a second water-cooled plate. The inlets of the first and second water-cooled plates are connected to an inlet pipe, and the outlets of the first and second water-cooled plates are connected to an outlet pipe. Thus, the first and second water-cooled plates are connected in parallel between the inlet and outlet pipes. Through the parallel connection of the first and second water-cooled plates, low-temperature water at the same temperature can be obtained simultaneously, thereby ensuring that the first and second water-cooled plates in the water-cooled heat exchanger have the same heat dissipation effect, which can improve the heat dissipation efficiency of the water-cooled heat exchanger. Furthermore, by regulating the low-temperature water, the heat dissipation precision of the first and second water-cooled plates can be controlled simultaneously, allowing for more accurate temperature regulation of the electrical components, ensuring that the electrical components operate at a suitable temperature and guaranteeing the safety and stability of their operation.

[0032] It should be noted that as the heat generated by the electrical components in the motor driver testing device increases, the demand for heat dissipation also increases. Therefore, to meet the increased heat dissipation demand, the water-cooled heat exchanger can include multiple water-cooled plates, each of which is connected in parallel. By using multiple water-cooled plates, the heat dissipation efficiency of the water-cooled heat exchanger can be further improved, so as to meet the heat dissipation demand when the electrical components generate more heat.

[0033] Optionally, combined Figure 1 and Figure 3 As shown, the water-cooled heat exchanger includes a first water-cooled plate and a second water-cooled plate. The inlet of the first water-cooled plate is connected to the inlet pipe, the outlet of the first water-cooled plate is connected to the inlet of the second water-cooled plate, and the outlet of the second water-cooled plate is connected to the outlet pipe.

[0034] Specifically, the water-cooled heat exchanger includes a first water-cooled plate and a second water-cooled plate. The inlet of the first water-cooled plate is connected to an inlet pipe, so that low-temperature water from outside the device is introduced into the first water-cooled plate through the inlet. The outlet of the first water-cooled plate is connected to the inlet of the second water-cooled plate, so that the low-temperature water flows through the first water-cooled plate to absorb heat from the electrical components and then flows into the second water-cooled plate. The outlet of the second water-cooled plate is connected to an outlet pipe, so that the high-temperature water formed after absorbing heat from the electrical components again through the second water-cooled plate is discharged through the outlet pipe into a water treatment device located outside the motor driver testing device. By connecting the first and second water-cooled plates in series, the low-temperature water, after absorbing heat on the first plate, can continue flowing into the second plate for further heat absorption. For example, when low-temperature water flowing through the first plate absorbs heat from electrical components, the temperature after heat absorption is still much lower than the component's current temperature due to the significant temperature difference between the water and the components. To improve the utilization rate of the input low-temperature water, water flowing from the first plate is introduced into the second plate to continue absorbing heat from the components. This ensures the low-temperature water is fully utilized in the water-cooled heat exchanger, improving its efficiency. It should be noted that when the temperature difference between the water and the components is large, more water-cooled plates can be connected in series to further enhance heat absorption and utilization.

[0035] Optionally, combined Figure 1 and Figure 4 As shown, the air-water heat exchanger includes an air-water heat exchanger shell, a heat exchange tube bundle, and a fan. The heat exchange tube bundle is disposed inside the heat exchanger shell. The water inlet of the heat exchange tube bundle is connected to the water inlet pipe, and the water outlet of the heat exchange tube bundle is connected to the water outlet pipe. A vent is provided on one side of the air-water heat exchanger shell, and the fan is installed on the vent. An air inlet is provided on the side of the air-water heat exchanger shell away from the vent.

[0036] Specifically, since magnetic components such as transformers may be large and unsuitable for heat absorption via water-cooled plates, a water-cooled heat exchanger can be installed next to the magnetic components for heat dissipation. The water-cooled heat exchanger includes a shell, a fan, and heat exchange tube bundles. The heat exchange tube bundles and fan are located inside the shell. The inlet of the heat exchange tube bundle is connected to an inlet pipe, and the outlet is connected to an outlet pipe, allowing low-temperature water to enter the heat exchange tube bundle from the inlet, absorbing heat from the air inside the shell and thus cooling the components. The air temperature inside the heat exchanger housing decreases, generating low-temperature air. The low-temperature water in the heat exchanger tube bundle absorbs heat and flows through the outlet into the connected outlet pipe. From there, it is discharged to a water treatment device located outside the motor drive test device, thus carrying away the absorbed heat. To improve the heat absorption efficiency of the heat exchanger tube bundle, it can be arranged in an S-shape inside the air-water heat exchanger housing, increasing the contact area between the tube bundle and the air inside the housing. This improves the heat absorption efficiency of the tube bundle and increases the cooling rate of the air in the air-water heat exchanger. A vent is located on one side of the air-water heat exchanger housing, and a fan is installed on the vent. An air inlet is located on the side of the air-water heat exchanger housing away from the vent. The operation of a fan draws warm air from the magnetic components into the water-air heat exchanger housing through the inlet. Inside the housing, the air is cooled by the absorption of heat by the low-temperature water in the heat exchange tube bundle. The temperature at the vent of the heat exchanger housing is lower than that at the inlet, while the inlet temperature is similar to that of the air surrounding the magnetic components in the motor driver testing device. The fan can also blow the cooled air from the heat exchanger housing towards the magnetic components requiring cooling, allowing heat exchange between the cool air and the heat emitted by the magnetic components, thus achieving cooling. The fan increases the airflow within the motor driver testing device and the heat exchanger housing, enabling the cooled air to quickly and accurately reach the magnetic components. Furthermore, the inlet allows warm air surrounding the magnetic components to enter the heat exchanger housing for cooling, further improving the heat dissipation efficiency of the heat exchanger. By using a water-cooled air exchanger, heat exchange tubes can be used to cool the magnetic components without introducing external air into the motor driver testing device. A fan then blows the cooled air onto the magnetic components to further cool them. This effectively improves the cooling efficiency of the magnetic components inside the motor driver testing device, maintaining them at a suitable temperature. It should be noted that the number and location of the water-cooled air exchangers can be adjusted according to the number of magnetic components and their heat generation, ensuring sufficient heat dissipation for the magnetic components inside the motor driver testing device while avoiding resource waste.

[0037] Optionally, such as Figure 1 As shown, the heat exchange system also includes a water inlet valve, which is located at one end of the water inlet pipe outside the motor driver test device. The water inlet valve is used to regulate the flow rate in the water inlet pipe.

[0038] Specifically, an inlet valve is installed on the water inlet pipe located outside the motor driver test device. This valve allows for the regulation of the flow rate in the inlet pipe. By adjusting the flow rate of the low-temperature water, the heat exchange system's heat dissipation effect on the motor driver test device can be effectively controlled. When the temperature of the electrical components in the motor driver test device is too high, the flow rate of the low-temperature water can be increased through the valve to improve the heat exchange effect on the internal electrical components. Otherwise, the flow rate can be appropriately reduced to control the internal temperature of the motor driver test device at a suitable level. This provides a stable operating environment for the internal electrical components of the motor driver test device, ensuring its long-term safe and stable operation.

[0039] Optionally, such as Figure 1 As shown, the heat exchange system also includes a pressure gauge, which is located at one end of the inlet pipe near the inlet valve, and is used to monitor the pressure in the inlet pipe.

[0040] Specifically, by placing the pressure gauge near the inlet valve, the pressure of the low-temperature water flowing out of the inlet valve can be monitored in real time. This pressure change allows for accurate adjustment of the low-temperature water pressure in the inlet pipe, thereby precisely controlling the flow rate of the low-temperature water in the inlet pipe and improving the ability to regulate the internal temperature of the motor driver testing device.

[0041] Optionally, the heat exchange system further includes an outlet valve, which is located at one end of the outlet pipe outside the motor driver test device, and is used to regulate the flow rate in the outlet pipe.

[0042] Specifically, the outlet valve is located at the end of the outlet pipe outside the motor driver test device. By controlling the opening degree of the outlet valve, the flow rate of the heat exchange medium (water) in the heat exchange system can be affected, thereby indirectly affecting the internal temperature of the motor driver test device. A smaller outlet valve opening increases the residence time of the heat exchange medium in the heat exchange system, thus preventing new low-temperature water from entering the heat exchange system and keeping the internal temperature of the motor driver test device relatively stable. A larger opening allows the heat exchange medium to flow out of the heat exchange system quickly, increasing the fluidity of the heat exchange medium in the heat exchange system. When the inlet valve is open appropriately, new low-temperature water can be continuously introduced, thereby quickly cooling the electrical components inside the motor driver test device and effectively improving the heat dissipation efficiency of the electrical components inside the motor driver test device.

[0043] Optionally, the heat exchange system further includes a flow meter, which is disposed at one end of the outlet pipe near the outlet valve, and the flow meter is used to monitor the flow rate in the outlet pipe.

[0044] Specifically, by placing the flow meter at the end of the outlet pipe near the outlet valve, the flow rate of the high-temperature water flowing out of the pipe can be displayed intuitively. The stability of the flow data can be used to determine whether the heat exchange system is operating normally. The flow meter provides data support for precise control of the flow rate of the high-temperature water, which facilitates accurate adjustment of the outlet valve. At the same time, flow monitoring helps to detect whether there are any leaks in the heat exchange system, thereby improving the safety and stability of the heat exchange system.

[0045] Optionally, the heat exchange system further includes an air inlet valve located at the end of the water inlet pipe, the air inlet valve being used to expel air from the water inlet pipe.

[0046] Specifically, an air inlet valve is installed at the end of the inlet pipe. This valve allows residual air to be expelled from the inlet pipe, preventing airlocks and ensuring a stable flow of low-temperature water, thus guaranteeing the normal operation of the heat exchange system. When the inlet pipe becomes blocked, the air inlet valve can be opened to allow high-pressure air to clear the blockage, ensuring stable flow. Furthermore, a single-phase air inlet valve can be installed to allow outside air to enter the inlet pipe, while the low-temperature water inside cannot be expelled through it. This allows for pressure regulation within the inlet pipe using external air, preventing pipe damage and maintaining system integrity.

[0047] This utility model provides a motor driver testing device, which includes at least one heat exchange system as described above.

[0048] The beneficial effects of the motor driver testing device in this embodiment compared to the prior art are the same as those of the heat exchange system described above, and will not be repeated here.

[0049] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
