Description
Technical Field
[0001] This utility model relates to the field of heat dissipation shell technology, specifically a rapid heat dissipation shell for airborne equipment. Background Technology
[0002] In the aviation field, airborne equipment (such as electronic control systems, sensors, and communication modules) generates a significant amount of heat during operation. If this heat cannot be dissipated in a timely manner, it can lead to decreased equipment performance, shortened lifespan, or even malfunction, seriously impacting flight safety. Traditional airborne equipment cooling solutions typically employ air cooling or simple liquid cooling structures. However, as aircraft demand increasingly higher levels of equipment integration, power density, and reliability, traditional cooling methods are gradually revealing the following limitations:
[0003] Traditional heat sink casings are often welded or bolted to the equipment housing. Disassembly and assembly require special tools, are time-consuming, and can easily damage the sealing structure. In addition, long-term heat dissipation may cause blockage inside the ventilation ducts, requiring cleaning. Furthermore, the integrated design of the coolant piping and heat dissipation structure means that partial failures require the entire structure to be replaced, resulting in high maintenance costs.
[0004] Due to the limited internal space of aircraft, traditional heat dissipation shells are difficult to adapt to the installation requirements of equipment of different sizes or power. When multiple devices are connected in parallel for heat dissipation, traditional solutions require additional complex piping design, which increases system weight and leakage risk, and makes it difficult to dissipate heat quickly. After long-term high-temperature operation, the heat dissipation pipes are prone to self-heating, thereby reducing the efficiency of heat dissipation.
[0005] To address the above shortcomings, a rapid heat dissipation housing for airborne equipment is proposed. Utility Model Content

The channel pipe 1 is disposed inside the positioning housing 2. The sealing cover 3 is disposed on the top of the positioning housing 2. A sliding groove 22 is formed on the inner side of the top of the positioning housing 2. A sliding bolt 32 corresponding to the sliding groove 22 is fixedly installed at the bottom of the sealing cover 3. The sliding bolt 32 is slidably installed inside the sliding groove 22 to realize the rapid installation and removal of the sealing cover 3.
[0033] The front end of the channel pipe 1 is provided with a heat outlet 11 and the back end is provided with a heat inlet 12. It is directly connected to the airborne equipment housing 8 and is used to conduct heat generated by the airborne equipment.

A single positioning housing 2 is inserted into the expansion bolt 71 of the adjacent positioning housing 2 through the expansion slot 7 to realize horizontal combination expansion installation. After splicing, the top sides of the adjacent positioning housing 2 fit tightly together to form a continuous heat dissipation surface.
[0034] like Figure 2 , 3 As shown, a positioning groove 21 is provided on the inner side of the positioning housing 2, and a sealing groove 31 corresponding to the positioning groove 21 is provided on the inner bottom of the sealing cover plate 3. The positioning groove 21 and the sealing groove 31 are tightly fitted with the outer surface of the channel pipe 1 to ensure that there are no gaps in the heat conduction path.

[0044] It should be noted that the cooling plate 5 is independent of the sealing cover plate 3, and is combined with the side clamping block 4, which improves the stability of the device and also facilitates individual replacement or maintenance, reducing maintenance costs.
[0045] The inner side of the manifold 53 is provided with a pipe that connects to the branch pipe 52 to ensure that the coolant flows along the designed path, allowing for segmented management and optimizing heat exchange efficiency.
[0046] It should be noted that the locking part 51 of the cooling plate 5 is inserted into the locking groove 41 of the side locking block 4, the diverter pipe 52 is inserted into the flow pipe 42, and the manifold port 53 of the cooling plate 5 is connected to the external coolant circulation system through the pipe.
