Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a cooling system for an unmanned aerial vehicle hangar. Background Art

[0002] With the rapid development of drone technology and the increasing number of applications, people are increasingly demanding drones that can perform continuous intelligent operations, especially in areas such as line inspection, emergency response, and topographic surveying. Currently, existing drones on the market are controlled by pilots and the batteries are manually replaced to continue the flight mission, which greatly reduces the efficiency of drone operations. Drone nests are often deployed in areas with extremely low or high ambient temperatures (-40 to 60 degrees). Too high a temperature will affect the safety of the battery, so it is particularly important to keep the backup battery inside the drone nest warm.

[0003] Existing drone charging hangars mostly use compressor air conditioners for cooling. This type of air conditioner is huge in size, heavy, expensive, difficult to maintain, and its use occasions are greatly limited. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a UAV hangar cooling system, which can cool the UAV charging warehouse with a smaller volume, has low cost and is easy to maintain.

[0008] A cold end fan is installed inside the charging station to drive the air inside the charging station to flow through the cold end refrigeration fins;

[0020] The cooling system in this application changes the existing air conditioning cooling system with a large volume and complex structure, and adopts heat conduction cooling, air circulation in the motor warehouse, and forced air cooling outside the motor warehouse.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0027] In order to solve the problem that the existing UAV charging hangars in the prior art mostly use compressor air conditioners for cooling, which are huge in size, heavy in weight, high in cost, difficult to maintain, and have greatly limited use occasions, such as Figure 1-Figure 3 As shown, this embodiment proposes a UAV hangar cooling system. Specifically, the UAV hangar cooling system is installed in the battery compartment 6. The UAV hangar cooling system includes a heat conduction component, which includes a hot-end heat sink 1 and a cold-end refrigeration fin 2, wherein the cold-end refrigeration fin 2 and the hot-end heat sink 1 can conduct heat, wherein the cold-end refrigeration fin 2 is located inside the charging warehouse, and the hot-end heat sink 1 is located outside the charging warehouse.

[0028] like Figure 1 The battery compartment 6 is a box structure, and the battery compartment 6 has a narrow portion whose cross-sectional area is smaller than that of the main body. The battery compartment 6 main body has a placement position for the drone battery 5 at the port corresponding to the narrow portion. After the drone battery 5 is placed in the placement position, the air flowing in from the narrow portion can be directly blown to the drone battery 5. The narrow portion can make the air flow to the drone battery 5 faster, forcing the drone battery 5 and the air to exchange heat.

[0029] In this embodiment, a cold end fan 7 is provided at the cold end refrigeration sheet 2. The function of the cold end fan 7 is to drive the air to circulate in the battery compartment 6. For example, the heat generated by the drone battery 5 is transferred to the surrounding air, and the air in the battery compartment 6 is driven by the cold end fan 7 to circulate in the battery compartment 6. After the air passes through the cold end refrigeration sheet 2, the heat is transferred to the cold end refrigeration sheet 2. Since the cold end refrigeration sheet 2 and the hot end heat sink 1 can conduct heat, the heat is dissipated from the hot end heat sink 1 to the air outside the battery compartment 6.

[0030] In this embodiment, the heat dissipation fan 3 is arranged adjacent to the hot end heat sink 1, and is used for forced air cooling of the hot end heat sink 1. Preferably, the heat dissipation fan 3 is arranged toward the hot end heat sink 1, so that the heat dissipation fan 3 can guide the ambient air to blow directly toward the hot end heat sink 1, thereby increasing the heat dissipation efficiency.

[0031] In a feasible embodiment, the hot-end heat sink 1 and the cold-end refrigeration fin 2 are an integrated metal component, and both the hot-end heat sink 1 and the cold-end refrigeration fin 2 are metal fins, which are easy to process, low in cost, and have very high heat dissipation efficiency.

[0032] In order to increase the efficiency of air circulation in the battery compartment 6, a circulating air duct 10 is provided in the charging warehouse, and the cold end fan 7 is installed in the circulating air duct 10 to guide the gas to directional circulation in the battery compartment 6. The circulating air duct 10 is arranged at a narrow portion. As a preferred embodiment, the cold end refrigeration sheet 2 is also located in the circulating air duct 10. Therefore, Figure 3 As shown, the air is driven by the cold end fan 7 from one side of the circulating air duct 10 to enter the circulating air duct 10, and after passing through the cold end refrigeration plate 2, it is output from the other end of the circulating air duct 10. In this embodiment, the openings at both ends of the circulating air duct 10 have a relatively far spacing, so that the air in the battery compartment 6 can form a generally clockwise or counterclockwise circulation to avoid air flow turbulence.

[0033] like Figure 2 As shown, the cooling system is installed at the front opening of the battery compartment 6, and a plate-shaped TEC fixing bracket 4 is installed at the cooling fan 3, and the TEC fixing bracket 4 is connected to the main structure of the cooling system through the air conditioning bracket 9.

[0034] In order to avoid condensation water during the cooling system operation, a condensation water receiving pan 8 is provided below the hot end heat sink 1 and the cold end refrigeration plate 2. Figure 1 As shown, the condensate receiving tray 8 generally has a stepped plate-like structure, which is connected to the TEC fixing bracket 4 by screws or buckles.

[0035] Preferably, the cooling fan 3 is a vortex fan, and a wind duct 11 is provided on the side of the vortex fan. A plate-shaped fixed bracket is provided on the front side of the cooling fan 3, and grilles are provided at the ends of the fixed bracket corresponding to the cooling fan 3 and the wind duct 11. That is, the cooling fan 3 guides the air to enter the area in contact with the hot end heat sink 1 through the first grille 41 on the fixed bracket, and the air enters the wind duct 11 after absorbing heat after contacting the hot end heat sink 1, and is guided by the wind duct 11 to pass through the second grille 42 and be discharged from the first grille 41.

[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
