Description

TECHNICAL FIELD

[0001] The present application relates to the field of spaceflight TT&C system environmental control technology, and particularly relates to an intelligent environmental control system for a phased array TT&C system. BACKGROUND

[0002] Phased arrays are used in many fields, but in the process of use, a large amount of heat will be emitted, and if the heat cannot be removed, the temperature of the entire phased array system will be very high, causing the phased array system to be unable to use. With the miniaturization and micro-miniaturization of high-power components, the heat flux density of the components is continuously increasing, and the thermal design of the entire system is becoming more and more important. Good cooling effect has become an increasingly important support for the entire system to have high reliability indicators.

[0003] In an array antenna, the antenna subarray is a key component unit, each antenna subarray contains 4 groups of transmitting components and 4 groups of receiving components. The transmitting and receiving components will generate heat when working, causing the surface temperature of the device to rise. The temperature rise leads to a decrease in device efficiency, which seriously affects the performance and reliability of the array antenna. In addition, the temperature of the antenna rises under the influence of sunlight and internal power cabinet module heating, which further affects the performance of the components. Therefore, the array antenna must increase the environmental control system, and how to design a set of environmental control system to ensure the normal use of the phased array is crucial. SUMMARY

[0033] The system uses a liquid-cooled source main unit subsystem to achieve the environmental control process of the radar system through liquid-cooled environmental control cycle. When the ambient temperature is higher than 10℃, the compressor cooling mode is activated. When the ambient temperature is lower than 5℃, the conventional liquid cooling mode is adopted. At the same time, the liquid-cooled source main unit subsystem has a coolant heating state, which can realize functions such as constant pressure liquid replenishment, liquid addition, load solution recovery, and liquid drainage.

[0034] Specifically, the system works as follows:

[0035] The cooling tower 2, the front end cooling unit 4, and the in-hood control cooling unit 3 are used to provide a cooling source for the entire system. The cooling tower 2 is a common cooling tower that provides water for several systems at the same time. The electric heater 13 is used to raise the temperature of the system when the temperature is low. The refrigeration system 22 is mainly based on the refrigeration principle of the compressor 26.

[0036] The array end cooling subsystem 9 is used to cool and circulate heat from the antenna components and power cabinet of the antenna subarray. The array end cooling subsystem 9 adopts a pipe network design. Through the flow distribution design of the pipe network, the temperature uniformity requirement of the antenna components is met. Heat from the transmitting and receiving components is conducted to the liquid cooling frame through a heat spreader, and then the liquid coolant carries the heat out of the subarray. Calculations show that a liquid supply temperature of 30℃ and a supply rate of 1.8L / min for a single subarray can meet the heat dissipation requirements. The liquid cooling pipe network is the "blood vessel" of the liquid cooling system, and its design structure directly determines the flow distribution of the liquid cooling system, thus affecting the overall heat dissipation effect of the system.

[0037] The liquid cooling source main unit subsystem provides circulating coolant to the array terminal cooling subsystem and the in-shell terminal environmental control subsystem, meeting the flow, temperature, and pressure requirements for heat dissipation in each subsystem. It features functions such as liquid storage, liquid supply, coolant cooling, coolant heating, coolant bypass, automatic replenishment, coolant recovery, and coolant degassing. The liquid cooling source main unit adopts a closed-loop system, achieving automatic control by receiving a central control signal. It operates in compressor cooling mode (when the ambient temperature is above 10℃) and conventional liquid cooling mode (when the ambient temperature is below 5℃), with coolant heating, constant pressure replenishment, liquid addition, liquid recovery, and liquid drainage.

[0038] The in-flight environmental control subsystem utilizes a liquid-cooled main unit to provide circulating coolant, which exchanges heat within the radome via fan coil heat exchangers, removing heat from the radome. Simultaneously, the flow rate of the circulating coolant is adjusted to regulate the heat exchange of the fan coil units in real time, ensuring the radome temperature remains stable between 10℃ and 30℃. Temperature control within the in-flight environmental control subsystem relies on the fan coil units. The inlet and outlet of the fan coil units are connected to the inside of the radome, and the coils are connected to the external liquid-cooled unit via piping. The air inside the radome exchanges heat with the coils or duct heaters, achieving temperature and humidity control within the radome. Factors such as solar radiation and convection, array surface, human presence, lighting, fresh air intake, and electromagnetic wave heat loss are considered. Furthermore, the system controller, based on detected temperature changes inside the radome, adjusts the opening of the electric valves within the 14 operating fan coil units and the number of duct heaters activated or deactivated. The system controls the temperature inside the radome. When all electric valves are in bypass mode and the temperature inside the radome is still too low, the air duct heaters are gradually activated. When all air duct heaters are stopped and the temperature is still too high, the electric valves are gradually adjusted to reduce the bypass flow of the solution. During cooling, the temperature of the coolant supplied by the liquid cooling unit is controlled within ±2℃. Using the difference between the radome feedback temperature and the set radome temperature, and its rate of change, as the control input, a PID control method is used to adjust the electric valves in real time to regulate the coolant flow through the coils, thereby changing the coils' cooling heat exchange capacity. This ensures that the temperature inside the radome remains within 5℃, guaranteeing that the temperature inside the radome is maintained within the target range.

[0039] The dehumidification subsystem 7 inside the enclosure is mainly used to maintain the indoor relative humidity at no higher than 65%RH. Since the air humidity value seriously affects the normal operation of the phased array telemetry and control system, dehumidification is required. A fan draws humid air into the dehumidifier, and through the heat exchanger, the water molecules in the air condense into water droplets, which are discharged through the drain pipe. The treated dry air is discharged outside the machine. This cycle keeps the indoor humidity at a suitable relative humidity, thus providing dry air. To improve the reliability of the equipment, four dehumidifying fan coil units (3 in use and 1 on standby) are arranged at the bottom of the enclosure. During the air circulation process, the air inside the enclosure is continuously dehumidified according to the humidity value, which can ensure that the humidity drops to the target value within 2 hours when the maximum humidity is 95%.

[0040] The in-radome fresh air subsystem is used to supply fresh air when maintenance personnel enter the radome to maintain and repair related equipment, ensuring the health of maintenance personnel;

[0041] The central control subsystem 5 monitors the real-time operating status of each subsystem of the phased array measurement and control system and the liquid-cooled environmental control system. After processing by the PCC data, it plays a role in controlling, displaying, protecting and alarming the system.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
