Description

Technical Field

[0001] This utility model relates to the field of radar cooling systems, specifically a low-conductivity radar coolant system. Background Technology

[0002] Currently, due to their high power and high heat density, radar electronic equipment still relies heavily on liquid cooling as the most mature and widely used cooling method. Most of the components in the coolant system, such as the cold plates and pipes, are made of metal. To extend the lifespan of these metal components, measures need to be taken to reduce pipe corrosion. The most significant issue is electrochemical corrosion caused by the continuous release of free ions from the system pipes. A common solution is to use a coolant composed of ethylene glycol, deionized water, and appropriate amounts of antioxidants and antifoaming agents to inhibit electrochemical corrosion. However, the additives in the coolant gradually weaken and become ineffective during use, causing the coolant to lose its corrosion-resistant function and leading to pipe corrosion. Furthermore, coolants with added oxidants and antifoaming agents can produce precipitates during use, causing pipe blockage and affecting heat exchange efficiency. Therefore, frequent coolant replacement and system cleaning are necessary, especially for large radar coolant systems, where each coolant replacement is extremely expensive. Utility Model Content

[0003] To address the aforementioned problems and shortcomings, this invention provides a low-conductivity radar coolant system that can reduce the frequency of coolant replacement and maintain system cleanliness.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A low-conductivity radar coolant system includes a main coolant circulation system and an auxiliary coolant circulation system; The main circulation system of coolant includes a supply pump (1), a heat dissipation device (2), and a solution tank (7) containing coolant.

[0014] Figure 1 This is a schematic diagram of the coolant circulation system in an embodiment of the present invention. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, this embodiment discloses a low-conductivity radar coolant system, including a coolant circulation system and a controller. The coolant circulation system includes a main coolant circulation system and an auxiliary coolant circulation system. The main coolant circulation system and the auxiliary coolant circulation system are controlled by the controller to switch the coolant flow direction.

[0017] The main coolant circulation system includes a supply pump 1, a heat dissipation device 2, a main filter 3, a flow meter 5, a bubble separator 6, a solution tank 7, and an expansion tank 8. The solution tank 7 stores coolant, which is composed of ethylene glycol and water. One outlet of the solution tank 7 is connected to the inlet of the supply pump 1 via a pipeline. The outlet of the supply pump 1 is connected to the inlet of the heat dissipation device 2 via a pipeline. The outlet of the heat dissipation device 2 is connected to the inlet of the main filter 3 via a pipeline. The outlet of the main filter 3 is connected to the inlet of the radar heat load 4 via a pipeline. The outlet of the radar heat load 4 is connected to the inlet of the flow meter 5 via a pipeline. The outlet of the flow meter 5 is connected to the inlet of the bubble separator 6 via a pipeline. The outlet of the bubble separator 6 is connected to one inlet of the solution tank 7 via a pipeline, thus forming the main coolant circulation. The expansion tank 8 is connected to the solution tank 7 via a pipeline to form a loop. The solution tank 7 is also equipped with a conductivity meter 9, which is used to detect the conductivity data of the coolant inside the solution tank 7.

[0018] The coolant auxiliary circulation system includes an auxiliary filter 10, a deionization device 11, a first electric three-way valve 12, a reservoir 13, an auxiliary filter 14, a second electric three-way valve 15, and a deionization pump 16. The deionization device 11 is filled with polishing resin. The other outlet of the solution tank 7 in the main coolant circulation system is connected via a pipeline to one port of the second electric three-way valve 15. The other port of the second electric three-way valve 15 is connected via a pipeline to the inlet of the deionization pump 16. The outlet of the deionization pump 16 is connected via a pipeline to one port of the first electric three-way valve 12. The other port of the first electric three-way valve 12 is connected via a pipeline to the inlet of the deionization device 11. The outlet of the deionization device 11 is connected via a pipeline to the inlet of the auxiliary filter 10. The outlet of the auxiliary filter 10 is connected via a pipeline to the other inlet of the solution tank 7. The third port of the first electric three-way valve 12 and the third port of the second electric three-way valve 15 are respectively connected to the reservoir 13 via pipelines.

[0019] In this embodiment, the controller is electrically connected to the liquid supply pump 1, the first electric three-way valve 12, the liquid storage tank 13, the second electric three-way valve 15, and the deionization pump 16. The conductivity meter 9 is electrically connected to the controller for signal transmission.

[0020] When the radar coolant system is activated, the main coolant circulation system begins operation. Coolant in solution tank 7 is pumped by supply pump 1 to heat dissipation device 2, where it dissipates heat. The cooled coolant is then filtered through main filter 3 and delivered to radar load 4, absorbing heat from the load. After its temperature rises, the coolant passes through flow meter 5 and bubble separator 6 before being piped back to solution tank 7, completing one cycle of the main coolant circulation system. Expansion tank 8 in the main coolant circulation system primarily buffers pressure fluctuations in solution tank 7, maintaining stable pressure throughout the system. Conductivity meter 9 monitors the conductivity of the coolant in solution tank 7 and feeds the conductivity value back to the controller.

[0021] When the radar coolant system is activated, if the conductivity value monitored by the conductivity meter 9 is higher than the set value, the controller sends a working command to the deion pump 16. The first electric three-way valve 12 switches to the state where the deionizer 11 and the deion pump 16 are connected, and the second electric three-way valve 15 switches to the state where the solution tank 7 and the deion pump 16 are connected. The deion pump 16 will then begin deionization circulation. The coolant in the main circulation system passes through the solution tank 7 and the second electric three-way valve 15, and is then pumped by the deion pump 16 through the first electric three-way valve 12 to the deionizer 11. After being filtered and purified by the deionizer 11, the coolant passes through the auxiliary filter 10 and returns to the solution tank 7, completing one cycle of deionization circulation in the auxiliary coolant circulation system.

[0022] When the radar coolant system is activated, the controller detects that the pressure in the main coolant circulation system is lower than the set pressure. The controller then sends a working command to the deion pump 16. The first electric three-way valve 12 switches to the connection state between the deionizer 11 and the deion pump 16, and the second electric three-way valve 15 switches to the connection state between the auxiliary filter 14 and the deion pump 16. The deion pump 16 then begins replenishing and pressurizing the coolant. The coolant in the reservoir 13, after passing through the auxiliary filter 14 and the second electric three-way valve 15, is pumped by the deion pump 16 and the first electric three-way valve 12 to the deionizer 11. After being filtered and purified by the deionizer 11, it passes through the auxiliary filter 10 and is then sent to the solution tank 7 of the main circulation system. When the pressure in the main circulation system rises to the system pressure set value, the second electric three-way valve 15 switches to the connection state between the solution tank 7 and the deion pump 16, and the deion pump 16 stops working. The auxiliary coolant circulation system then completes the constant pressure replenishment function of the coolant system.

[0023] When the radar coolant system is activated, the controller monitors the main coolant circulation system pressure. If the pressure exceeds the set pressure, the controller sends a working command to the deion pump 16. The first electric three-way valve 12 switches to the connection between the reservoir 13 and the deion pump 16, and the second electric three-way valve 15 switches to the connection between the solution tank 7 and the deion pump 16. The deion pump 16 then begins its draining and depressurization process. The coolant in the solution tank 7, after passing through the second electric three-way valve 15, is pumped by the deion pump 16 to the reservoir 13 via the first electric three-way valve 12. When the main circulation system pressure drops to the system pressure set value, the second electric three-way valve 12 switches to the connection between the deionizer 11 and the deion pump 16, and the deion pump 16 stops working. The auxiliary coolant circulation system then completes the draining and depressurization function of the coolant system.
