Description

Technical Field

[0001] This utility model belongs to the field of power electronics testing technology, specifically relating to a water-cooled aging system. Background Technology

[0002] An aging chamber is a temperature chamber device used for aging testing of power electronic products. It is an important experimental device for product reliability testing. The aging chamber itself is a relatively sealed temperature chamber. Aging testing is an indispensable functional test and good product screening process in the production process. Typically, an aging chamber can age dozens or even hundreds of products per batch. The high-power inverters themselves emit a lot of heat in the sealed space, causing the aging environment temperature to be higher than the actual application environment. The aging environment requires a relatively stable thermal circulation environment. Excessive temperature will cause the inverter to overheat. Existing aging chambers usually use air-cooled aging, where the inside of the aging chamber exchanges heat with the outside natural air to achieve circulation. The existing air-cooled aging mode has the following technical disadvantages:

[0003] 1) The aging efficiency and heat dissipation capacity are low. Natural wind circulation makes it difficult to control the closed environment within a relatively stable temperature range. Especially in summer, when the external environment temperature is already high, it is impossible to achieve the purpose of heat exchange to reduce the internal temperature of the aging chamber.

[0004] 2) The temperature varies in different locations within the aging chamber, resulting in uneven ambient temperature. The temperature is relatively lower near the heat exchange air inlet and relatively higher further away from the air inlet.

[0005] 3) It is impossible to monitor the temperature of each inverter at its location during aging in real time; it can only reflect the temperature of the general environment, and the aging data lacks accuracy. Utility Model Content

[0006] The purpose of this invention is to overcome the problems of unstable aging environment and inaccurate aging data, and to propose a water-cooled aging system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water-cooled aging system includes an aging chamber body, a product aging rack, and a water-cooling device. The product aging rack is installed inside the aging chamber body, and a temperature monitoring device and a water-cooling monitoring device are installed on the product aging rack. The water-cooling device is installed outside the aging chamber body. The aging chamber body is provided with a water-cooling air inlet and a heat exchange air outlet, and the water-cooling device is connected to the water-cooling air inlet and the heat exchange air outlet, respectively.

[0009] Furthermore, the product aging rack includes a pallet, with a heat dissipation vent at the bottom of the pallet, circulating fans on both sides of the pallet, and an inverter to be aged placed on the pallet.

[0010] Furthermore, the water-cooled air inlet and the heat exchange air outlet are arranged adjacent to each other. The water-cooled air inlet is located at the top and the lower side of the aging chamber body, and the heat exchange air outlet is located at the top and the lower side of the aging chamber body. The water-cooled air inlet at the top of the aging chamber body is arranged opposite to the air inlet of the inverter to be aged.

[0011] Furthermore, the pallet has several layers.

[0012] Furthermore, a temperature monitoring device is installed at the front end of each pallet, and a water-cooling monitoring device is installed on both sides of each pallet.

[0013] Furthermore, the water cooling device includes a blower, a plate heat exchanger, a chilled water unit, a cooling tower, a cooling water pump, a chilled water pump, and a water storage tank;

[0014] The cooling water outlet pipe of the chiller and the first outlet of the plate heat exchanger are connected to the inlet of the cooling water tower. The outlet of the cooling water tower is connected to the first inlet of the plate heat exchanger and the cooling water inlet pipe of the chiller via a cooling water pump.

[0015] The air outlet of the air handling unit is connected to the inlet of the water storage tank. The outlet of the water storage tank is connected to the chilled water inlet pipe of the chilled water unit and the second inlet of the plate heat exchanger via a chilled water pump. The outlet of the water storage tank is connected to the chilled water outlet pipe. The chilled water outlet pipe of the chilled water unit and the second outlet of the plate heat exchanger are connected to the air inlet of the air handling unit.

[0016] The air outlet of the blower is connected to the water-cooled air inlet, and the air inlet of the blower is connected to the heat exchange air outlet.

[0017] Furthermore, several air handling units are provided.

[0018] Furthermore, three water-cooled air inlets are provided on the top of the aging chamber body, three heat exchange air outlets are provided on the top of the aging chamber body, and two water-cooled air inlets are provided on the lower side of the aging chamber body.

[0019] Furthermore, the temperature monitoring device and the water-cooling monitoring device are connected to the monitoring and control system, and the water-cooling device is connected to the water-cooling control system.

[0020] Furthermore, the aging chamber body includes an outer wall, a transparent observation wall, and a wall insulation layer.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] This invention proposes a water-cooled aging system. The aging chamber body is equipped with a water-cooled air inlet and a heat exchange air outlet. The water-cooled air inlet introduces air cooled by a water-cooling device, while the heat exchange air outlet discharges hot air generated during the aging process, forming an airflow circulation. This allows for uniform and rapid heat dissipation. A temperature monitoring device monitors the temperature inside the aging chamber in real time, ensuring the aging temperature remains within a set range and accurately reflecting the overall temperature of the aging environment. The water-cooling monitoring device measures the operating status of the water-cooling device, which cools the air entering the aging chamber. By introducing water-cooling technology, the air temperature can be reduced more effectively, thus providing a more stable aging environment. The water-cooling device is connected to the water-cooled air inlet and the heat exchange air outlet of the aging chamber. Cooled air is sent into the aging chamber through the water-cooled air inlet, and then the hot air discharged from the heat exchange air outlet is received for further cooling and circulation. This solves the problems of unstable aging environment and inaccurate aging data.

[0023] Furthermore, the air is compressed and cooled to the required set temperature by a water cooling device. This cooled air is then discharged into the aging chamber through a blower to reduce the internal ambient temperature. The monitoring and control system then implements feedback control of the cooling air temperature and the aging environment temperature to achieve a relatively stable aging environment, ensuring the aging chamber is in a relatively stable temperature environment through hot and cold circulation. It also enables real-time monitoring of the temperature of each aging process station to prevent abnormalities such as overheating and shutdown during product aging. Attached Figure Description

[0033] Example 1

[0034] See Figure 1 and Figure 2A water-cooled aging system includes an aging chamber body 1, a product aging rack 2, and a water-cooling device 3. The product aging rack 2 is installed inside the aging chamber body 1. A temperature monitoring device 21 and a water-cooling monitoring device 22 are installed on the product aging rack 2. The water-cooling device 3 is installed outside the aging chamber body 1. The aging chamber body 1 is provided with a water-cooling air inlet 11 and a heat exchange air outlet 12. The water-cooling device 3 is connected to the water-cooling air inlet 11 and the heat exchange air outlet 12 respectively.

[0035] By connecting the water-cooling device 3 to the water-cooling air inlet 11 and heat exchange air outlet 12 of the aging chamber body 1, the system can achieve efficient heat exchange and cooling, rapidly reducing the temperature inside the aging chamber. Especially when a large amount of heat is generated during product aging, it can quickly remove residual heat, ensuring the product undergoes aging testing in a stable temperature environment. The temperature monitoring device 21 installed on the product aging rack 2 can monitor the temperature inside the aging chamber in real time, thereby achieving precise temperature control. For products requiring specific temperature conditions for aging, this ensures the accuracy and reliability of test results. Because the system can control the temperature quickly and accurately, it can significantly improve the efficiency of product aging tests. Simultaneously, the water-cooling monitoring device 22 can monitor the operating status of the water-cooling system, promptly identify and resolve problems, avoid test interruptions, and further guarantee test efficiency. Compared with traditional air-cooling systems, water-cooling systems typically have a higher energy efficiency ratio, utilizing energy more effectively. Furthermore, through precise temperature control, unnecessary energy consumption can be reduced, achieving energy conservation and environmental protection. A stable temperature environment helps reduce thermal stress caused by temperature changes in equipment, thereby extending the equipment's service life. At the same time, the water-cooling system can also reduce noise and vibration generated during equipment operation, improving the stability and reliability of the equipment. This water-cooled aging system can adapt to the aging needs of products of different sizes and types. By adjusting parameters such as the power and flow rate of the water-cooling device 3, it can flexibly respond to different temperature requirements.

[0036] The product aging rack 2 includes a pallet 23 with a heat dissipation vent 231 at the bottom and circulating fans on both sides. Inverters to be aged are placed on the pallet 23. A water-cooled air inlet 11 and a heat exchange air outlet 12 are arranged adjacent to each other. The water-cooled air inlet 11 is located at the top and lower side of the aging chamber body 1, and the heat exchange air outlet 12 is located at the top and lower side of the aging chamber body 1. The water-cooled air inlet 11 at the top of the aging chamber body 1 is opposite to the air inlet of the inverter to be aged. The pallet 23 has several layers. A temperature monitoring device 21 is installed at the front end of each layer, and a water-cooled monitoring device 22 is installed on both sides of each layer.

[0037] The heat dissipation vents 231 at the bottom of the pallet 23 and the circulating fans on both sides can form effective air convection, accelerating the airflow around the inverters to be aged, thereby improving heat dissipation efficiency. Temperature monitoring devices 21 at the front of each pallet can monitor the temperature in real time, ensuring that the aging environment of each inverter is within the set temperature range, improving the accuracy of temperature control. Water-cooled air inlets 11 and heat exchange outlets 12 are arranged adjacent to each other, located at the top and lower sides of the aging chamber body 1 respectively. This layout facilitates efficient water-cooling circulation, accelerating heat transfer and dissipation. The top water-cooled air inlet 11 is positioned opposite the air inlet of the inverter to be aged, ensuring that the cooling water directly removes the heat generated by the inverter, improving the efficiency of the water-cooling system. Real-time monitoring and precise control by the temperature monitoring device 21 ensures the consistency of the aging test environment, thereby improving the accuracy and reliability of the test results. The water-cooling monitoring device 22 can monitor the operating status of the water-cooling system in real time, promptly identifying and addressing potential problems, avoiding test interruptions or errors caused by system failures. The pallet 23 has several layers, allowing for adjustments to the number of inverters and layers as needed, thus improving system adaptability and flexibility. The configuration of the circulating fan and water cooling system can be flexibly adjusted according to the inverter's aging requirements and testing environment to meet the aging test needs of different products. Compared to traditional air-cooled systems, water cooling systems typically have higher energy efficiency ratios and lower noise levels, contributing to energy conservation and environmental protection goals.

[0038] The water-cooling unit 3 includes a blower 31, a plate heat exchanger 32, a chiller 33, a cooling tower 34, a cooling water pump 35, a chilled water pump 36, and a water storage tank 37. The cooling water outlet pipe of the chiller 33 and the first outlet of the plate heat exchanger 32 are connected to the inlet of the cooling tower 34. The outlet of the cooling tower 34 is connected to the first inlet of the plate heat exchanger 32 and the cooling water inlet pipe of the chiller 33 via the cooling water pump 35. The air outlet of the blower 31 is connected to the water storage tank 37. The inlet of water tank 37 is connected, and the outlet of water tank 37 is connected to the chilled water inlet pipe of chilled water unit 33 and the second inlet of plate heat exchanger 32 via chilled water pump 36. The outlet of water tank 37 is connected to chilled water outlet pipe, and the chilled water outlet pipe of chilled water unit 33 and the second outlet of plate heat exchanger 32 are connected to air inlet of air handling unit 31. Air outlet of air handling unit 31 is connected to water-cooled air inlet 11, and air inlet of air handling unit 31 is connected to heat exchange air outlet 12. Several air handling units 31 are provided.

[0039] In this embodiment, the air handling unit 31 is the air processing section, which sends cooled air into the aging chamber and receives hot air from the aging chamber for further cooling. The air outlet of the air handling unit 31 is connected to the inlet of the water storage tank 37, sending the cooled air into the system for circulation. The air inlet of the air handling unit 31 is connected to the chilled water outlet pipe of the plate heat exchanger 32, receiving the cooled air. The air outlet of the air handling unit 31 is connected to the water-cooled air inlet 11, sending the cooled air into the aging chamber. The air inlet of the air handling unit 31 is connected to the heat exchange outlet, receiving the hot air discharged from the aging chamber.

[0040] In this embodiment, the plate heat exchanger 32 is a key component for heat exchange. It has two independent fluid channels: one for cooling water (from the chiller 33 and cooling tower 34), and the other for chilled water (from the water storage tank 37 and air handling unit 31). The cooling water channel is connected to the chiller 33 and cooling tower 34 to cool the system and remove heat. The chilled water channel is connected to the water storage tank 47 and air handling unit 31 to cool the air entering the air handling unit 31.

[0041] In this embodiment, the chiller unit 33 is the core of the refrigeration system, providing chilled water for cooling the air. The chiller unit 33's cooling water outlet pipe is connected to the cooling tower 34 to dissipate heat. The chiller unit 33's cooling water inlet pipe is connected to the cooling water pump 36 and the plate heat exchanger 32 to receive cooled water. The chilled water inlet pipe of the chiller unit 33 is connected to the water storage tank 37 and the plate heat exchanger 32 to receive uncooled water. The chilled water outlet pipe of the chiller unit 33 is connected to the plate heat exchanger 32 and the air handling unit 31 to provide cooled water. The cooling tower 34 dissipates heat, releasing the heat emitted by the chiller unit 33 into the atmosphere. The cooling water pump 35 drives the cooling water to circulate between the chiller unit 33, the plate heat exchanger 32, and the cooling tower 34. The chilled water pump 36 drives the chilled water to circulate between the chiller unit 33, the plate heat exchanger 32, and the water storage tank 37.

[0042] In this embodiment, the water storage tank 37 stores and buffers chilled water to ensure the stability and continuity of system operation. The inlet of the water storage tank 37 is connected to the air outlet of the air handling unit 31 to receive pre-cooled air. The outlet of the water storage tank 37 is connected via the chilled water pump 36 to the chilled water inlet pipe of the chilled water unit 33 and the second inlet of the plate heat exchanger 32, providing chilled water. The outlet of the water storage tank 37 is also connected to a chilled water outlet pipe for discharging or reusing chilled water.

[0043] In this embodiment, the chilled water device 3 operates as follows: cooling water flows out from the cooling water outlet pipe of the chiller 33, passes through the first outlet of the plate heat exchanger 32, and enters the cooling tower 34. In the cooling tower 34, the cooling water releases heat and cools. The cooled water is then pumped back by the cooling water pump 35 to the first inlet of the plate heat exchanger 32 and the cooling water inlet pipe of the chiller 33, completing the cooling water circulation.

[0044] Chilled water flows from the storage tank 37 and enters the chilled water inlet pipe of the chilled water unit 33 via the chilled water pump 36. In the chilled water unit 33, the chilled water is cooled. The cooled chilled water enters the second inlet of the plate heat exchanger 32, where it exchanges heat with the air cooled by the chilled water. The cooled chilled water then flows out from the second outlet of the plate heat exchanger 32 and enters the air inlet of the air handling unit 31 to cool the air. The cooled air then flows out from the air outlet of the air handling unit 31 and enters the storage tank 37 for buffering and storage.

[0045] Hot air flows out from the heat exchange outlet and enters the air inlet of the air handling unit 31. Inside the air handling unit 31, the hot air exchanges heat with chilled water and is cooled. The cooled air flows out from the air outlet of the air handling unit 31 and enters the water storage tank 37 for further treatment. The treated air flows out from the outlet of the water storage tank and, via the chilled water pump, re-enters the plate heat exchanger 32 and the chilled water unit 33 for circulating cooling. Finally, the cooled air enters the aging chamber from the water-cooled air inlet 11 for product aging testing.

[0046] Three water-cooled air inlets 11 are installed on the top of the aging chamber body 1, three heat exchange air outlets 12 are installed on the top of the aging chamber body 1, and two water-cooled air inlets 11 are installed on the lower side of the aging chamber body 1. Temperature monitoring device 21 and water-cooled monitoring device 22 are connected to the monitoring and control system, and water-cooling device 3 is connected to the water-cooling control system. The aging chamber body 1 includes an outer wall, a transparent observation wall, and a wall insulation layer.

[0047] Example 2

[0048] See Figure 1 and Figure 2 A water-cooled aging system includes an aging chamber body 1, a product aging rack 2, a water-cooling device 3, a temperature monitoring device 21, and a water-cooling monitoring device 22.

[0049] The aging chamber body 1 consists of an outer wall, a transparent observation wall, and a wall insulation layer. The interior of the aging chamber body includes a product aging placement rack 2, a temperature monitoring device 21, a water-cooled monitoring device 22, and a circulating fan. The top has a water-cooled air inlet 11, etc.

[0050] The product aging rack 2 includes a pallet 23, with a heat dissipation vent 231 at the bottom of the pallet 23 to prevent the air outlet at the bottom of the inverter from being blocked. A temperature monitoring device 21 is installed on the front of the product aging rack 2 to detect the temperature at the left, middle and right positions of the inverter. There are two circulating fans on both sides of the pallet 23 to ensure that the air at the same work station can circulate.

[0051] See Figure 3The water-cooling device 3 is located on the outside of the aging chamber body 1. The air handling unit 31 is connected to the air inlet of the aging chamber body 1. There are three air inlets distributed on the top left, center and right of the aging chamber body 1. When the airflow is downward, it is perpendicular to the air inlet of the inverter to ensure that the air inlet of the inverter draws in cold air. There are two air inlets distributed on the bottom side of the aging chamber body 1. One is to ensure that the internal air can circulate and turbulent, and the other is to ensure that the temperature of the aging chamber is uniform from top to bottom. The water-cooling device 3 compresses water-cooled air to form cold air and discharges it into the interior of the aging chamber body 1. At the same time, the hot air inside the aging chamber is discharged to the cooling system for cooling through heat exchange via plate heat exchanger 32. By using the water-cooling device 3 to cool the air instead of natural wind, heat exchange circulation between the inside and outside of the aging chamber is achieved. The ambient temperature is controllable and stable, the temperature control is more precise, and the process consistency is better.

[0052] Each product aging rack 2 has 3 layers, with one workstation on each layer. Three temperature monitoring devices 21 are installed on the left, middle and right sides of the inverter at each workstation to monitor the ambient temperature at the three positions in real time. The detection data is fed back to the control system. If the ambient temperature exceeds the required aging temperature of the inverter, the inverter will alarm and stop or reduce its rating.

[0053] Each product aging rack 2 has a water-cooled monitoring device 22 on each side at the top, middle, and bottom positions. It mainly detects whether the temperature is uniform at different points in the entire aging environment and the temperature at different locations in the aging chamber. When uneven temperature or local temperature exceeds the range, the data is fed back to the control system of the water-cooled device 3 in real time. By adjusting the cold air exhaust volume and cold air temperature, the temperature in the aging chamber is kept in a relatively stable environment.

[0054] By testing at different locations, we ensure that each aging machine is in the same environment, thus avoiding local overheating that could cause inverter derating or shutdown, and improving test pass rate and quality reliability.

[0055] The working principle of a water-cooled aging system is as follows:

[0056] When the system is started, the water cooling device 3 starts working, cooling the outside air and sending it into the aging chamber through the water cooling air inlet 11.

[0057] Inside the aging chamber, the inverter products to be aged are placed on the product aging rack 2, and are monitored in real time by the temperature monitoring device 21 and the water cooling monitoring device 22.

[0058] As the aging process progresses, the air temperature inside the aging chamber gradually increases. At this point, the hot air is exhausted through the heat exchange outlet and cooled again by the water-cooling device 3.

[0059] The air cooled by the water-cooling device 3 re-enters the aging chamber through the water-cooled air inlet 11, forming a cycle.
