Technical Field

[0001] This utility model relates to the field of precise temperature control, and in particular to a precision temperature control system for a self-balancing inert environment. Background Technology

[0002] Existing temperature control systems are mostly used for temperature regulation, but they struggle to achieve high-precision temperature control and cannot solve problems such as temperature overshoot and precise temperature control during the temperature regulation process. In high and low temperature regulation, the energy transfer and conversion efficiency is low, resulting in significant energy loss. Traditional temperature control systems primarily use kerosene, heat transfer oil, and nitrogen as the temperature medium, which has significant limitations. Kerosene and heat transfer oil pose a risk of leakage and contamination. Summary of the Invention

[0005] Preferably, the dual-stage high-pressure vortex blower is used to pressurize the circulating medium in the circulation pipeline to ensure directional transport of the medium; the high-temperature pipeline electric heater is used to heat the circulating medium in the circulation pipeline; the wound tube heat exchanger is used to exchange heat between circulating media at different temperatures in the circulation pipeline; the microchannel plate heat exchanger is used to transfer heat out of the system when the temperature in the circulation pipeline is too high; the transonic escape device is used to compensate for system parameter fluctuations caused by environmental heat intrusion, consumable use, or changes in operating conditions; the medium temperature monitoring unit is used to monitor the temperature of the circulating medium in the circulation pipeline; the medium pressure monitoring unit is used to monitor the pressure of the circulating medium in the circulation pipeline; and the safety protection unit is used to release pressure when the pressure in the circulation pipeline exceeds a limit value.

[0006] Preferably, the safety protection unit includes a safety valve and a cryogenic pressure relief regulating valve. The safety valve is located on the circulation pipeline between the two valves, and the cryogenic pressure relief regulating valve is installed on the pipeline at the inlet front end of the two-stage high-pressure vortex blower.

[0007] Preferably, the medium temperature monitoring unit employs a temperature monitoring sensor, which is respectively installed at the inlet and outlet positions of the two-stage high-pressure vortex blower, the high-temperature pipeline electric heater, the wound tube heat exchanger, the microchannel plate heat exchanger, and the transonic escape device; the medium pressure monitoring unit employs a pressure monitoring sensor, which is respectively installed at the inlet and outlet positions of the two-stage high-pressure vortex blower, the high-temperature pipeline electric heater, the wound tube heat exchanger, the microchannel plate heat exchanger, and the transonic escape device.

[0008] Preferably, the inlet and outlet pipelines of the cooling medium are equipped with a flow regulating device and a temperature monitoring device. The flow regulating device is used to adjust the flow rate of the cooling medium to meet the heat dissipation requirements of the microchannel plate heat exchanger, and the temperature monitoring device is used to monitor the temperature of the cooling medium.

[0009] The beneficial effects of this utility model are:

[0010] (1) This application uses a combination of a two-stage high-pressure vortex blower, a high-temperature pipeline electric heater, a wound tube heat exchanger, a microchannel plate heat exchanger, and a transonic escape device to achieve precise control of the temperature of the circulating medium. The temperature control is stable, the temperature adjustable range is large, the overall structure is compact, the area occupied is small, and the control unit can perform real-time control with timely and effective response.

[0011] (2) The dual-stage high-pressure vortex blower has an intelligent automatic compensation function, which can automatically compensate the pressure required by the system based on the pressure value at its inlet and the pressure feedback in the circulation pipeline, so as to provide controllable and continuous flow power for the circulating medium and meet the transportation and circulation needs of the circulating medium.

[0012] (3) The spiral tube heat exchanger recovers and reuses the heat energy between two media at different temperatures in the circulating pipeline. Through its specially designed parallel flow channel and internal high specific surface area micro array structure, the spiral tube heat exchanger enables the high temperature medium and the low temperature medium to exchange heat in the opposite flow, realizing the step-by-step recovery and efficient transfer of heat energy in the system. Compared with ordinary shell and tube heat exchangers, it has incomparable advantages. It has a wider applicable temperature range, stronger adaptability to thermal shock, and can also eliminate thermal stress itself. It has high compactness, sufficient flow field development, and no flow dead zone, which can ensure more sufficient heat exchange.

[0013] (4) The high-temperature pipeline electric heater provides a precise and controllable heat source for the circulating medium through the Joule effect. The high-temperature pipeline electric heater adopts a multi-stage coupled heat exchange structure made of nanocomposite heating material, which can realize the high-efficiency and high-precision generation and transfer of heat energy between the heat exchange structure and the temperature medium. It also uses model predictive control algorithm to deal with complex transient heat loads, thereby improving the temperature control accuracy and reliability of the system during the heating process.

[0014] (5) The microchannel plate heat exchanger transfers excess heat energy to the cooling medium with high heat capacity through convection heat exchange. The heat exchange efficiency is significantly higher than that of traditional air-cooled heat exchangers. The cooled medium after heat exchange is sent out through the outlet pipeline of the cooling medium to complete the heat recovery and utilization. By adjusting the flow rate and temperature of the cooling medium, sensitive temperature control of the circulating medium can be achieved. By exchanging heat with the circulating medium through the microchannel plate heat exchanger, the system can be ensured to operate continuously and stably within the safe temperature range.

[0015] (6) The transonic escape device can precisely control the pressure, volume and flow rate in a closed loop system, ensuring that the temperature medium maintains a stable single-phase state or a controllable vaporization process at extremely low temperatures, thereby maintaining the stability and accuracy of the system.

[0016] (7) By installing a low-temperature pressure relief regulating valve at the inlet of the two-stage high-pressure vortex blower, the pressure in the circulating pipeline will be automatically released when the pressure exceeds the rated maximum pressure, thus ensuring the safe operation of the system.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] like Figure 1 As shown, a self-balancing inert environment precision temperature control system includes a two-stage high-pressure vortex fan 3, a high-temperature pipeline electric heater 2, a wound tube heat exchanger 1, a microchannel plate heat exchanger 4, a transonic escape device 5, and a control unit 6. The wound tube heat exchanger 1, the two-stage high-pressure vortex fan 3, and the microchannel plate heat exchanger 4 are connected sequentially through a circulation pipeline 7. The wound tube heat exchanger 1 and the transonic escape device 5 are connected through the circulation pipeline 7. The wound tube heat exchanger 1, the high-temperature pipeline electric heater 2, and the transonic escape device 5 are also connected sequentially through the circulation pipeline 7. The circulation pipeline 7 is equipped with valves that control the opening and closing of each circulation pipeline 7 and the flow rate of the circulating medium. The valves are electrically connected to the control unit 6. The circulation pipeline 7 is also equipped with a temperature monitoring unit, a medium pressure monitoring unit, and a safety assurance unit. The medium temperature monitoring unit uses a temperature monitoring sensor, and the medium pressure monitoring unit uses a pressure monitoring sensor. Both temperature and pressure monitoring sensors are located at the inlet and outlet positions of the two-stage high-pressure vortex blower 3, the high-temperature pipeline electric heater 2, the wound tube heat exchanger 1, the microchannel plate heat exchanger 4, and the transonic escape device 5. The safety assurance unit includes a safety valve and a cryogenic pressure relief regulating valve. The safety valve is located on the circulation pipeline between two valves, with one safety valve between every two valves. The cryogenic pressure relief regulating valve is installed on the pipeline at the inlet of the two-stage high-pressure vortex blower 3, automatically releasing pressure when the pressure in the circulation pipeline 7 exceeds the rated maximum pressure, ensuring the safety of the system pressure. The temperature monitoring sensor, pressure monitoring sensor, safety valve, and cryogenic pressure relief regulating valve are all electrically connected to the control unit 6.

[0023] The two-stage high-pressure vortex blower 3 is used to pressurize the circulating medium in the circulation pipeline 7 to ensure directional transport of the medium. The two-stage high-pressure vortex blower 3 can achieve efficient compression and directional transport of the circulating medium, satisfying the transport and circulation of the medium within the circulation pipeline 7. It provides controllable and continuous flow power for the medium by generating an airflow higher than ambient pressure, providing the necessary pressure conditions for the circulation pipeline 7. It has an intelligent automatic compensation function, which can automatically compensate for the required system pressure based on the pressure at the medium inlet of the two-stage high-pressure vortex blower 3 and combined with system pressure feedback data analysis. This type of blower has advantages such as low noise, oil-free operation, long service life, and maintenance-free operation. Its structure is more robust and precise than the traditional single-stage blower, and the maximum flow rate can reach 2480 m³ / h. 3 / h, in this embodiment, a Wind Vic FVK series two-stage high-pressure vortex blower can be used. A pressure control unit is installed at the inlet of the two-stage high-pressure vortex blower. The pressure control unit is electrically connected to the control unit and is used to adjust the inlet pressure of the two-stage high-pressure vortex blower 3 according to the instructions of the control unit.

[0024] The high-temperature pipe electric heater 2 provides a precise and controllable heat source for the system through the Joule effect. It employs a multi-stage coupled heat exchange structure made of nanocomposite heating materials, achieving high-efficiency and high-precision generation and transfer of heat energy between the heat exchange structure and the temperature medium. Optimized thermal insulation shell design significantly reduces convective heat transfer between the high-temperature pipe electric heater and the environment, improving heating efficiency. The high-temperature pipe electric heater 2 utilizes model predictive control algorithms to handle complex transient heat loads, ensuring accurate and reliable temperature control during the system's heating process. This product can be directly applied through market procurement, and existing technology can meet the requirements of this embodiment.

[0025] In this system, the wound tube heat exchanger 1 serves as a highly efficient thermal management device. Its core function is to achieve heat recovery and reuse between two fluids at different temperatures. Its structure employs a specially designed parallel flow channel and an internal high specific surface area micro-array structure, enabling non-contact heat exchange between the high-temperature and low-temperature media in counter-current flow, achieving cascaded heat recovery and efficient transfer within the system. Compared to ordinary shell-and-tube heat exchangers, the wound tube heat exchanger 1 used in this embodiment has unparalleled advantages. It has a wide applicable temperature range, is adaptable to thermal shock, can self-eliminate thermal stress, and has a very high compactness. Due to its special structure, its flow field is fully developed, with no dead zones. Most notably, by setting multiple tube sides (single shell side), it can simultaneously exchange heat between multiple fluids within a single device. The wound tube heat exchanger 1 is formed by alternately winding heat transfer tubes in a spiral pattern within the space between the core and outer cylinders. The spiral directions of adjacent layers of spiral heat transfer tubes are opposite, and a specially shaped spacer is used to maintain a certain distance between them. In this embodiment, the Spiral Wounded Heat Exchanger series of spiral wound tube heat exchangers from the brand LDK Solar can be selected to meet the system requirements.

[0026] The microchannel plate heat exchanger 4 is connected to inlet and outlet pipelines for the cooling medium. These pipelines contain a high-heat-capacity medium. Flow regulating devices and temperature monitoring devices are installed on the inlet and outlet pipelines. The flow regulating device adjusts the flow rate of the cooling medium to meet the heat dissipation requirements of the microchannel plate heat exchanger 4, while the temperature monitoring device monitors the temperature of the cooling medium. The microchannel plate heat exchanger 4 is used in the system to transfer excess heat energy to the high-heat-capacity cooling medium through convection heat transfer, ensuring continuous and stable operation of the equipment within a safe temperature range. Its heat exchange efficiency is significantly higher than that of traditional air-cooled heat exchangers, making it suitable for high heat flux density scenarios. Sensitive temperature control of the circulating medium in the system can be achieved by adjusting the flow rate and temperature of the cooling medium. This type of heat exchanger uses advanced Micro Plate technology, which can significantly reduce energy consumption. It occupies little space, is easy to install, and is convenient to maintain. In this embodiment, the SONDEX series microchannel plate heat exchanger from Danfoss can be selected.

[0027] The transonic escape device 5 is mainly used to compensate for system parameter fluctuations caused by environmental heat intrusion, consumable use, or changes in operating conditions, thereby maintaining system stability and accuracy. In a closed-loop system, it can precisely control pressure, volume, and flow rate, ensuring that the temperature medium maintains a stable single-phase state or a controllable vaporization process at extremely low temperatures. It provides a stable flow and pressure supply of the temperature medium to the user end, playing a role in pressure stabilization and continuous liquid supply, thus ensuring the reliability and efficiency of the entire cryogenic system. In this embodiment, the device can directly use an existing Laval nozzle.

[0028] like Figure 2 As shown, the system can establish and train a prediction model, build a model database, collect temperature data through the temperature sensor of the medium temperature monitoring unit, collect pressure data through the pressure sensor of the medium pressure monitoring unit, and compare the collected data with preset data.

[0029] When there is a difference in temperature data, the model database intervenes and provides a temperature feedforward to the high-temperature pipe heater / transonic escape device. The high-temperature pipe heater / transonic escape device responds, and the temperature of the circulating medium is adjusted. The temperature monitoring unit feeds back the corrected monitoring results, which are then compared with the preset data to enter the next cycle. When there is no difference in temperature data, the model database predicts based on the collected environmental heat intrusion data and provides a temperature balance to the high-temperature pipe electric heater 2 / transonic escape device 5 to balance the environmental heat intrusion and maintain steady-state temperature control.

[0030] When there is a difference in the pressure data, the model database intervenes and provides a pressure feedforward to the dual-stage high-pressure vortex blower 3 and the safety protection unit. The dual-stage high-pressure vortex blower 3 and the safety protection unit respond, and the pressure monitoring unit feeds back the corrected monitoring results, which are then compared with the preset data to enter the next cycle. When there is no difference in the data, the model database predicts the pressure based on the set pressure value and provides a pressure control quantity to the dual-stage high-pressure vortex blower 3 and the safety protection unit to maintain the pressure stability of the circulation pipeline.

[0031] The specific methods for applying this system to achieve precise temperature control include two modes: cooling and heating. The specific method for heating is as follows:

[0032] S1: The control unit 6 presets the rated temperature and rated pressure values ​​that need to be achieved in the circulation pipeline 7;

[0033] S2: The circulating medium enters the internal pipeline of the wound tube heat exchanger 1 from the first input end of the wound tube heat exchanger 1, and then enters the high temperature pipeline electric heater 2 through the circulation pipeline 7 from the first output end of the wound tube heat exchanger 1.

[0034] S3: The high-temperature pipeline electric heater 2 heats the circulating medium. After being heated, the circulating medium enters the internal pipeline of the application equipment after passing through the transonic escape device 5. Heat is released in the internal pipeline of the application equipment to increase the temperature of the application equipment.

[0035] S4: After the circulating medium releases heat in the application equipment, it returns to the first input end of the wound tube heat exchanger 1, and step S2 is executed.

[0036] The specific method of refrigeration is as follows:

[0037] S1: The control unit 6 presets the rated temperature and rated pressure values ​​that need to be achieved in the circulation pipeline 7;

[0038] S2: Under the pressurization action of the dual-stage high-pressure vortex blower 3, the circulating medium circulates along the closed-loop circulation pipeline of high-pressure vortex blower 3-microchannel plate heat exchanger 4-wound tube heat exchanger 1-high-pressure vortex blower 3. The circulating medium exchanges heat with the high heat capacity medium provided in the cooling medium inlet and outlet pipelines in the microchannel plate heat exchanger 4, so that the temperature of the circulating medium is reduced. The circulating medium after the temperature is reduced enters the wound tube heat exchanger 4 through the second input end of the wound tube heat exchanger 1.

[0039] S3: The circulating medium enters the wound tube heat exchanger 1 through the first input end of the wound tube heat exchanger 1 and exchanges heat with the low temperature circulating medium entering through the second input end. After the temperature of the circulating medium entering through the first input end decreases, it enters the internal pipeline of the application equipment through the transonic escape device 5 and releases cold energy in the internal pipeline of the application equipment to reduce the temperature of the application equipment.

[0040] S4: After the circulating medium enters the wound tube heat exchanger 1 from the second input end for heat exchange, it is output to the two-stage high-pressure vortex fan 3 from the second output end, and step S2 is executed.

[0041] The control unit 6 compares the rated temperature values ​​of each node with the rated temperature values ​​fed back by the medium temperature monitoring unit installed on the circulation pipeline 7, and adjusts the real-time temperature of the circulating medium in the circulation pipeline by adjusting the flow rate and temperature of the cooling medium, the pressurization degree of the dual-stage high-pressure vortex fan 3, and the flow rate of the circulating medium in the circulation pipeline 7.

[0042] In this embodiment, the control unit 6 mainly integrates the electrical modules, intelligent temperature control software, and industrial control computer required for the temperature control process. This enables the system to automatically and accurately control the temperature according to the set temperature gradient curve, while also allowing for manual intervention in temperature control. The temperature control method of this system differs from the traditional PID temperature control algorithm. It employs Model Predictive Control (MPC) for temperature control. Traditional temperature regulation systems use PID temperature compensation algorithms, which have low temperature regulation accuracy and cannot avoid temperature overshoot. This system uses MPC for precise temperature control. By combining various data fed back by the system with an intelligent analysis model, it can predict the control input in advance, fundamentally avoiding temperature overshoot and achieving ultra-high precision temperature control.

[0043] This application utilizes a combination of a two-stage high-pressure vortex fan 3, a high-temperature pipeline electric heater 2, a wound tube heat exchanger 1, a microchannel plate heat exchanger 4, and a transonic escape device 5, along with a model database. Even when the real-time monitored temperature has reached the preset temperature, it still takes compensatory measures in advance for factors such as environmental heat intrusion based on the predictions of the model database. Similarly, even when the real-time monitored pressure has reached the preset pressure, it still adjusts the pipeline pressure in advance based on the predictions of the model database, so as to achieve steady-state temperature and pressure control in the medium pipeline.

[0044] This system boasts a wide adjustable temperature range, a compact overall structure, and a small footprint. Real-time control is achieved through control unit 6, ensuring timely and effective response. Distinguishing itself from traditional temperature regulation systems in its temperature control principle, it achieves near-quantum-level precision in temperature control, with efficient energy transfer and conversion at each stage. It is suitable for various temperature media, covering inert atmospheres such as liquid nitrogen and liquid helium. Traditional temperature regulation systems can only achieve accurate temperature control within the range of -120℃ to +100℃, with an accuracy of ±3℃. In contrast, the temperature control system of this application achieves precise and effective temperature control within the range of -260℃ to +180℃, meeting a control accuracy of ±0.5℃ in the range of -200℃ to +150℃, and ±1.5℃ in the ranges of -260℃ to -200℃ and +150℃ to +180℃.

[0045] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
