Description

Technical Field

[0001] This utility model relates to a temperature control system, and more particularly to a gas-liquid two-phase self-circulating temperature control system. Background Technology

[0002] In existing technologies, air-cooled, ambient-temperature high-pressure blowers are used as pressure compensation units in temperature control systems to compensate for pressure losses of high-pressure media along pipelines, valves, and heat sinks. However, due to the limitation that traditional high-pressure blowers can only operate within the ambient temperature range, a media reheating unit needs to be added to the temperature control system. This unit first heats / cools the media requiring pressure compensation to the ambient temperature range before it enters the blower for pressure compensation. This heating / cooling process results in significant unnecessary energy loss, and also leads to complex temperature pipeline layouts, low space utilization, and excessively high equipment costs. Summary of the Invention

[0003] This invention addresses the technical problems in existing temperature control systems where the medium needs to be heated or cooled before pressurization, resulting in energy loss, complex pipeline layout, low space utilization, and high equipment investment costs. It provides a gas-liquid two-phase self-circulating temperature control system that reduces energy loss, improves temperature control efficiency, simplifies pipeline layout, improves space utilization, and has a lower overall cost.

[0004] Therefore, the technical solution of this utility model is a gas-liquid two-phase self-circulating temperature control system, including a pressurization unit, a temperature compensation unit, and a pressure and temperature monitoring unit. The temperature compensation unit is connected to the outlet pipeline of the medium carrier in the space environment. The pressurization unit adopts a wide-temperature-range high-pressure fan. The pressure and temperature monitoring unit includes a pressure monitoring sensor and a temperature monitoring sensor. A medium compensation unit is provided on the rear pipeline of the pressurization unit. An electric heater is provided on the parallel pipeline of the medium compensation unit. The output end of the medium compensation unit is connected to the inlet pipeline of the medium carrier in the space environment. A temperature compensation unit is provided at the front end of the pressurization unit, and a pressure and temperature monitoring unit is provided at the front end of the temperature compensation unit.

[0005] Preferably, the temperature compensation unit is a water-cooled heat exchanger.

[0006] Preferably, pressure and temperature monitoring units are provided between the pressurization unit and the medium compensation unit, and at the output end of the medium compensation unit.

[0007] Preferably, a safety protection unit and a pressure control unit are also provided. The safety protection unit is located at the rear end of the pressurization unit, and the pressure control unit is located at the front end of the temperature compensation unit.

[0008] Preferably, the safety protection unit includes a safety valve and a pressure relief valve, used to automatically relieve pressure when the pressure in the pipeline is overloaded.

[0009] Preferably, the various units in the system are connected by pipelines, which are made of seamless stainless steel pipes.

[0010] The beneficial effects of this utility model are:

[0011] (1) This application expands the applicable temperature range of the medium by using a wide temperature range high pressure blower as a pressurization unit, avoiding energy loss caused by large-scale adjustment of the medium temperature. Furthermore, by setting a temperature compensation unit at its front end, when the medium temperature exceeds the applicable range of the wide temperature range high pressure blower, temperature compensation can be performed through the temperature compensation unit. However, since the wide temperature range high pressure blower has a wide applicable temperature range, the temperature difference that needs to be compensated is relatively small, which can also effectively reduce energy loss.

[0012] (2) The system has fewer components, a simple structure, convenient pipeline connection, and low overall cost;

[0013] (3) Setting up pressure and temperature monitoring units at multiple nodes can effectively monitor the temperature and pressure at each point in the pipeline. When the temperature is not up to standard, it can be adjusted by water-cooled heat exchanger or electric heater. When the pressure is low, it can be increased by pressurization unit. When the pressure is too high or too low, it can be adjusted by pressure control unit. The feedback is timely and effective. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments.

[0018] like Figure 1As shown, a gas-liquid two-phase self-circulating temperature control system includes a pressurization unit 7, a temperature compensation unit 8, and a pressure and temperature monitoring unit 6. The temperature compensation unit 8 is connected to the outlet pipeline of the heat sink and other media carriers 2 in the space environment simulation device 1. The pressurization unit 7 uses a wide-temperature-range high-pressure fan; in this embodiment, a GHBH-025 Gaorui fan is selected, but other models from other manufacturers can also be used. The pressure and temperature monitoring unit 6 includes a pressure monitoring sensor and a temperature monitoring sensor. A media compensation unit 3 is installed on the rear pipeline of the pressurization unit 7, and an electric heater 4 is installed on the parallel pipeline of the media compensation unit 3. The output end of the media compensation unit 3 is connected to the inlet pipeline of the heat sink and other media carriers 2 in the space environment simulation device 1. The temperature compensation unit 8 is installed at the front end of the pressurization unit 7, and the pressure and temperature monitoring unit 6 is installed at the front end of the temperature compensation unit 8.

[0019] Temperature compensation unit 8 uses a water-cooled heat exchanger. When the medium temperature exceeds the applicable range of the wide-temperature-range high-pressure blower, temperature compensation can be achieved through the water-cooled heat exchanger of temperature compensation unit 8. However, since the wide-temperature-range high-pressure blower has a wide applicable temperature range, the temperature difference that needs to be compensated is relatively small, which can also effectively reduce energy loss. When the temperature is low, the medium can also be heated by electric heater 4 before entering the heat sink and other medium carriers 2, which can improve the temperature control efficiency.

[0020] Pressure and temperature monitoring units 6 are provided between the pressurization unit 7 and the medium compensation unit 3, and at the output end of the medium compensation unit 3. Multiple pressure and temperature monitoring units 6 can also be set at other nodes according to the working conditions to effectively monitor the temperature and pressure at each point in the pipeline. When the pressure is low, it is increased by pressurization unit 7.

[0021] The system also includes a safety protection unit 5 and a pressure control unit 9. Safety protection unit 5 includes a safety valve and a pressure relief valve, used to automatically release pressure when the pipeline pressure is overloaded. Safety protection unit 5 can be located after the pressurization unit 7, and pressure control unit 9 can be located before the temperature compensation unit 8. Both safety protection unit 5 and pressure control unit 9 can be installed at the front and rear ends of each unit as needed. If the pressure is too high or too low, it can be adjusted through pressure control unit 9, providing timely and effective feedback.

[0022] The various units in the system are connected by pipelines, which are made of seamless stainless steel pipes.

[0023] This application expands the applicable medium temperature range by using a wide-temperature-range high-pressure fan as the booster unit 7, avoiding energy loss caused by large-scale temperature adjustments of the medium. Furthermore, by setting a temperature compensation unit 8 at its front end, it effectively ensures that the temperature of the medium entering the booster unit 7 is suitable and does not exceed its applicable range, thereby improving the reliability of system operation. The system has fewer components, a simple structure, and convenient pipeline connections, thus reducing the overall cost.

[0024] 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.
