Description

Technical Field

[0001] This application relates to the field of liquid cooling devices for T / R modules suitable for high heat flux density and high overload environments, and more particularly to a liquid cooling device for T / R modules, a T / R module, and a radar suitable for high heat flux density and high overload environments. Background Technology

[0002] With the rapid development of radar technology, high power, high integration, and miniaturization have become key development directions for radar transceiver (T / R) modules. Research shows that the reliability of electronic devices is closely related to temperature; when the temperature is between 70℃ and 80℃, the reliability of electronic devices decreases by 50% for every 10℃ increase in temperature. Therefore, with the development of high-power modules, heat dissipation has gradually become a key technology to be addressed in high-power T / R modules. A certain radar T / R module has high heat flux density, high front-end power consumption, and severe heat accumulation. To meet the requirements of heat dissipation and temperature uniformity, a liquid cooling system is used to cool the radar front end. In addition, considering the usage requirements, this radar also needs to be designed for airdrop adaptability, as the liquid cooling device must withstand impacts of tens of times the force of gravity during airdrop. In conclusion, there is an urgent need to develop a liquid cooling device suitable for high heat flux density and high overload environments to meet the usage requirements of this radar.

[0003] Currently, most published patents focus on improving the heat dissipation capacity of liquid cooling plates. Some patents enhance heat dissipation by optimizing fins and heat-conducting pillars; others disclose liquid cooling plates used to cool N battery cells arranged in one direction; still others disclose a liquid cooling plate with an alternating hot and cold pipe structure, in which heat pipes are embedded to enhance heat dissipation. In summary, currently published patents improve the heat dissipation capacity of liquid cooling plates through methods such as optimizing fins, adding heat-conducting pillars, and embedding heat pipes, but there is little research on the temperature uniformity and overload resistance of liquid cooling plates.

[0005] To achieve the above objectives, the first aspect of this application provides a liquid cooling device for T / R modules suitable for high heat flux density and high overload environments, comprising: a mounting plate and a liquid cooling cavity disposed on the mounting plate; the liquid cooling cavity has multiple branches, as well as a main liquid inlet and a main liquid return path that are isolated from each other; fins are fixedly provided in each of the multiple branches, the main liquid inlet path and the main liquid return path; each branch is arranged in parallel and is not interconnected with each other, and each branch's first end is connected to the main liquid inlet path, and each branch's second end is connected to the main liquid return path.

[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0020] The technical problem to be solved by this invention is to address the challenges of high heat flux density and high overload environment in radar applications by conducting design and performance research on liquid cooling devices for high overload T / R components. While ensuring lightweight and high strength, this invention effectively solves the problems of poor temperature distribution and low heat dissipation efficiency of liquid cooling plates in T / R components.

[0021] Reference Figure 1 The first embodiment of this application provides a liquid cooling device for T / R modules suitable for high heat flux density and high overload environments. The liquid cooling device for T / R modules suitable for high heat flux density and high overload environments may include: a mounting plate 1 and a liquid cooling cavity 13 disposed on the mounting plate 1; the liquid cooling cavity 13 has multiple branches inside, as well as a main liquid inlet 5 and a main liquid return 6 that are isolated from each other; fins 12 are fixedly provided in the multiple branches, the main liquid inlet 5 and the main liquid return 6; each branch is arranged in parallel and is not connected to each other, and each branch's first end is connected to the main liquid inlet 5, and each branch's second end is connected to the main liquid return 6.

[0022] Specifically, the coolant flows from the main inlet channel 5 to each branch channel. Within each branch channel, the coolant makes full contact with several fins 12 to remove heat from the T / R assembly, and then collects in the main return channel 6 before leaving the liquid cooling plate. This continuous circulation removes heat, ensuring the T / R assembly operates within a safe temperature range. The parallel connection of multiple non-interconnected branches ensures that the coolant will not short-circuit. The fins 12 increase the contact area between the liquid cooling device and the coolant, enhancing the heat dissipation capacity of the liquid cooling device, and also increase the strength of the liquid cooling device, ensuring it meets the requirements for resisting high overload impacts. In summary, this application, through optimized flow channel layout and the parallel connection of multiple flow channels, ensures that the liquid cooling device meets the requirements for resisting high overload impacts while also possessing good temperature uniformity and heat dissipation capabilities, thus meeting the requirements for radar operation.

[0023] Continue to refer to Figure 1In the embodiments of this application, the mounting plate 1 is rectangular, and the main inlet channel 5 and the main return channel 6 are respectively disposed on the inner sides of two adjacent sides of the mounting plate 1. This increases the meandering of the flow channels of each branch, thereby increasing the travel distance of the coolant and carrying away more heat.

[0024] Continue to refer to Figure 1 In the embodiments of this application, the main liquid inlet 5 and the main liquid return 6 are respectively provided with a liquid inlet 3 and a liquid return 4, and both the liquid inlet 3 and the liquid return 4 are located on the same side of the mounting plate 1. The fact that the liquid inlet 3 and the liquid return 4 are located on the same side of the mounting plate 1 can reduce the difficulty of the layout of the liquid cooling device and realize the matrix arrangement of multiple liquid cooling devices.

[0025] refer to Figure 1 and Figure 2 In the embodiments of this application, each branch is located between the main liquid inlet path 5 and the main liquid return path 6. This also reduces the difficulty of liquid cooling device layout and improves the overall integrity of the liquid cooling device.

[0026] refer to Figure 1 and Figure 2 In the embodiments of this application, the branches are isolated from each other by reinforcing ribs 14. By locally adding reinforcing ribs 14, the liquid cooling device can be guaranteed to withstand high overload impacts, and the branches can be isolated from each other to ensure that the entire liquid cooling device has good temperature uniformity.

[0027] Continue to refer to Figure 1 In the embodiments of this application, the difference in the number of fins 12 in each branch does not exceed 5. This further ensures that the entire liquid cooling device has good temperature uniformity.

[0028] Continue to refer to Figure 2 In the embodiments of this application, each branch includes a first branch 7, a second branch 8, a third branch 9, a fourth branch 10, and a fifth branch 11 arranged parallel to the main liquid inlet 5. The five branches are arranged in parallel and are not interconnected. The coolant inlet temperature and flow rate of the five branches are the same, which can further ensure that the entire liquid cooling device has good temperature uniformity.

[0029] refer to Figure 3 Based on the above embodiments, this application also provides a T / R assembly, including: a liquid cooling device for T / R assemblies suitable for high heat flux density and high overload environments as provided in any of the foregoing embodiments; and a T / R assembly module 2 disposed on the side of the liquid cooling cavity 13 away from the mounting plate 1. In this embodiment, the liquid cooling device can cool 9 sets of T / R assembly modules 2.

[0030] Based on the above embodiments, this application also provides a radar, including the T / R component provided in the foregoing embodiments.

[0031] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
