Description

Technical Field

[0001] This utility model relates to the field of airborne chassis technology, and in particular to an airborne chassis that uses liquid cooling for heat dissipation. Background Technology

[0002] Airborne chassis are specialized enclosure structures used in the aerospace field to specifically house, secure, and protect various electronic devices (such as navigation systems, communication modules, and control units) on aircraft or spacecraft. They must meet stringent aerospace environmental requirements, withstanding extreme conditions such as high altitude and low temperature, high pressure differentials, severe vibration, electromagnetic interference, and shocks. Simultaneously, they must be lightweight and highly reliable, ensuring stable operation of internal equipment while adapting to the space layout and weight constraints of aircraft. They are critical support components for the normal operation of avionics systems.

[0003] Currently, most domestic airborne equipment uses forced air cooling and liquid cooling. Forced air cooling uses fans to drive airflow. However, due to the high ambient temperature, forced air cooling compresses the temperature difference, resulting in low heat dissipation efficiency and noise caused by vibration when the fan blades rotate. Liquid cooling requires liquid cooling plates to be installed inside the chassis, working with pipes and coolant flow to remove heat. However, liquid cooling plates can become loose due to external mechanical vibration and the vibration generated by the coolant flow. This requires disassembling the chassis and tightening bolts and nuts to secure them, increasing maintenance complexity and time costs.

[0004] Therefore, it is necessary to provide a new airborne chassis that uses liquid cooling to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an airborne chassis that uses liquid cooling for heat dissipation.

[0006] The airborne chassis with liquid cooling provided by this utility model includes: a chassis body, mounting plates fixedly connected to the rear sides of both the top and bottom ends of the chassis body, a heat dissipation window installed on the inner rear wall of the chassis body, a receiving box fixedly connected to the top of the chassis body, heat dissipation fins fixedly connected to the outside of the receiving box, a variable frequency liquid cooling pump installed on the top of the chassis body, a two-way pipe fixedly connected to the output end of the variable frequency liquid cooling pump, a cooling pipe fixedly connected to the output end of the two-way pipe, liquid cooling plates fitted to both sides of the inner wall of the chassis body, multiple U-shaped clamping blocks fixedly connected to the adjacent side of the two liquid cooling plates, an inlet pipe fixedly connected to the end of the cooling pipe away from the two-way pipe, a circulation pipe fixedly connected to the end of the inlet pipe away from the cooling pipe, a phase change cooling jacket symmetrically fixedly connected to the right side of the top of the chassis body, multiple insert rods fixedly connected to the distant side of the two liquid cooling plates, multiple fitting grooves opened on both sides of the chassis body, and tightening components installed on the outside of the insert rods.

[0007] Preferably, the tightening assembly includes a washer, the inner ring wall of which is inserted into the outer side of the insert rod, and the outer side of the insert rod is threaded with a nut.

[0008] Preferably, the input end of the variable frequency liquid cooling pump is connected to the heat dissipation fins via a pipe.

[0009] Preferably, the cooling pipe is a dense serpentine flow channel fixed to the liquid cooling plate by a U-shaped clamping block, and the outer side of the circulating pipe is fixedly connected to the inner ring wall of the phase change cooling jacket.

[0010] Preferably, the end of the circulation tube furthest from the access tube is fixedly connected to the interior of the housing, and the outside of the insertion rod is inserted into the inner wall of the housing body.

[0011] Preferably, the outer surface of the gasket fits into the inner wall of the groove.

[0012] Preferably, one side of the nut contacts the outer side of the chassis body, and one side of the washer contacts and presses against the side of the nut closest to the chassis body.

[0013] Compared with related technologies, the airborne chassis with liquid cooling provided by this utility model has the following advantages: This invention utilizes a liquid cooling circulation system composed of a variable frequency liquid cooling pump, cooling pipes, liquid cooling plates, and phase change cooling jackets, combined with heat dissipation fins and heat dissipation windows for auxiliary heat dissipation. This system can efficiently remove the heat generated by the electronic equipment inside the chassis, without being limited by excessively high ambient temperatures. It can maintain a stable and efficient heat dissipation effect over a wider temperature range, ensuring that the internal electronic equipment is always in a suitable temperature environment and ensuring stable operation.

[0014] This utility model adopts a tightening assembly design of plug rod, washer, and nut. When the liquid cooling plate becomes loose due to vibration, etc., there is no need to disassemble the chassis. The tightening and fixing operation can be completed by simply tightening the nut on the outside of the chassis. This avoids the complicated process brought about by traditional chassis disassembly maintenance, greatly reduces maintenance time and labor costs, and also reduces the risk of failure such as dust intrusion and secondary damage to components caused by disassembling the chassis, thus improving the convenience and reliability of equipment maintenance.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 4 An airborne chassis employing liquid cooling includes a chassis body 1, which serves as the core load-bearing structure of the entire device. Mounting plates 2 are fixedly connected to the rear sides of both the top and bottom ends of the chassis body 1. These mounting plates 2 facilitate the connection and fixation of the chassis body 1 to other structures of the airborne equipment, ensuring the chassis remains stable in the airborne environment. A ventilation window 3 is installed on the rear inner wall of the chassis body 1, with finely distributed ventilation holes to effectively promote airflow between the inside and outside of the chassis, aiding in the dissipation of internal heat. A [missing information - likely a device or component] is fixedly connected to the top of the chassis body 1. The container 4 is used to store coolant. A large number of heat dissipation fins 5 are fixedly connected to its exterior. These heat dissipation fins 5 have a densely arranged thin sheet structure, which greatly increases the contact area with the air and can quickly dissipate the heat of the coolant in the container 4 to the surrounding air. A variable frequency liquid cooling pump 6 is installed at the top of the chassis body 1. The input end of the variable frequency liquid cooling pump 6 is connected to the heat dissipation fins 5 through a sealed pipe, which can ensure that the coolant flows stably in the pipe. The output end of the variable frequency liquid cooling pump 6 is fixedly connected to a two-way pipe 7.

[0020] Cooling pipe 8 is a key component for liquid cooling. The output end of the two-way pipe 7 is fixedly connected to cooling pipe 8. Specifically, the end of the two-way pipe 7 connected to cooling pipe 8 is equipped with a quick connector, while the end of the cooling pipe 8 connected to the two-way pipe 7 is equipped with a matching socket. This quick connector and socket combination allows for rapid connection while ensuring a tight connection to prevent coolant leakage. Liquid cooling plates 9 are fitted to both sides of the inner wall of the chassis body 1. The liquid cooling plates 9 are made of a metal material with good thermal conductivity. Multiple U-shaped clamping blocks 10 are fixedly connected to the adjacent sides of the two liquid cooling plates 9. These U-shaped clamping blocks 10 can fix the cooling pipe 8 in place. Because the cooling pipe 8 has a dense serpentine flow channel, fixing it to the liquid cooling plate 9 with the U-shaped clamping blocks 10 increases the contact area between the coolant and the liquid cooling plate 9, improving heat exchange efficiency. An inlet pipe 11 is fixedly connected to the end of the cooling pipe 8 away from the two-way pipe 7, and a circulation pipe 11 is fixedly connected to the end of the inlet pipe 11 away from the cooling pipe 8. The return pipe 12, specifically, has a quick connector at one end where the inlet pipe 11 connects to the circulation pipe 12, and a matching socket at the other end where the circulation pipe 12 connects to the inlet pipe 11. This method allows for quick connection, convenient operation, and reliable connection. The end of the circulation pipe 12 away from the inlet pipe 11 is fixedly connected to the interior of the housing 4, allowing the coolant to flow back to the housing 4 to complete the circulation. A phase change cooling jacket 13 is symmetrically fixedly connected to the top right side of the chassis body 1. The exterior of the circulation pipe 12 is fixedly connected to the inner wall of the phase change cooling jacket 13. The phase change cooling jacket 13 is filled with a phase change medium. When the coolant flows through the circulation pipe 12, the phase change medium can absorb the heat of the coolant and undergo a phase change, thereby cooling the coolant. Multiple plug rods 14 are fixedly connected to the opposite side of the two liquid cooling plates 9. The exterior of the plug rods 14 is inserted into the inner wall of the chassis body 1 to achieve the connection and positioning of the liquid cooling plates 9 and the chassis body 1. Multiple mating grooves 15 are provided on both the left and right sides of the chassis body 1.

[0021] A tightening assembly is installed on the outside of the insertion rod 14. The tightening assembly includes a washer 16. The outside of the washer 16 fits into the inner wall of the mating groove 15, which ensures that the washer 16 will not shift after installation. The inner ring wall of the washer 16 is inserted into the outside of the insertion rod 14 for easy installation. A nut 17 is threaded onto the outside of the insertion rod 14. One side of the nut 17 contacts the outside of the chassis body 1. One side of the washer 16 contacts and presses against the side of the nut 17 near the chassis body 1. By tightening the nut 17, the liquid cooling plate 9 can be fixed to the chassis body 1 by the fit between the washer 16 and the mating groove 15 and the threaded connection between the nut 17 and the insertion rod 14.

[0022] The working principle of the airborne chassis with liquid cooling provided by this utility model is as follows: When the airborne chassis using liquid cooling begins operation, firstly, the variable frequency liquid cooling pump 6 starts, which drives the coolant to flow out of the container 4. After initial cooling by the heat dissipation fins 5, the coolant enters the variable frequency liquid cooling pump 6 through pipes. Then, the variable frequency liquid cooling pump 6 delivers the coolant to the two-way pipe 7, which in turn diverts the coolant into the cooling pipe 8. At this time, the cooling pipe 8, acting as a dense serpentine flow channel, is fixed to the liquid cooling plate 9 by multiple U-shaped clamping blocks 10. As the coolant flows within the cooling pipe 8, it exchanges heat with the liquid cooling plate 9. The liquid cooling plate 9 absorbs the heat generated by the electronic equipment inside the chassis body 1. Then, the coolant that has completed the heat exchange flows through the cooling pipe 8 to the inlet pipe 11. The inlet pipe 11 carries the coolant into the circulation pipe 12. The outside of the circulation pipe 12 is fixed to the inner ring wall of the phase change cooling jacket 13. During the flow, the phase change cooling jacket 13 will use the latent heat of phase change of the phase change medium to further cool the coolant. After that, the cooled coolant flows back to the container box 4 through the circulation pipe 12 to complete one circulation and heat dissipation process of the coolant. During the initial installation of the liquid cooling plate 9, the tightening assembly is operated first. First, the washer 16 is inserted into the mating groove 15, and then the washer 16 is placed on the outside of the plug rod 14. Next, the nut 17 is inserted and then rotated. The nut 17 rotates on the external thread of the plug rod 14, gradually approaching the outer side of the chassis body 1. At the same time, the nut 17 will squeeze the washer 16, making the washer 16 fit tightly with the mating groove 15, thereby firmly fixing the liquid cooling plate 9 and reducing the possibility of loosening due to vibration. However, during long-term use, the liquid cooling plate 9 may also loosen due to the loosening of the threads between the nut 17 and the plug rod 14. When it loosens, it is not necessary to disassemble the chassis. The nut 17 can be tightened again from the outside to fix the liquid cooling plate 9. In addition, the heat dissipation window 3 on the inner wall of the rear side of the chassis body 1 will also assist in heat dissipation, dissipating some of the heat inside the chassis to the external environment, further ensuring that the electronic equipment inside the chassis is in a suitable temperature environment and ensuring its stable operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
