The housing includes a casing, an air conditioning compartment, an electronic component compartment, a battery charging compartment, and a miniature air conditioner. Both the electronic component compartment and the air conditioning compartment are located within the casing. The battery charging compartment is used to charge the UAV's battery. The miniature air conditioner is installed within the air conditioning compartment. The air outlet, cold air supply channel, first cold air storage channel, second cold air storage channel, and electronic component compartment of the miniature air conditioner are sequentially and sealed together.

Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV nest based on air-cooled circulating air duct heat dissipation. Background Technology

[0002] A drone is an unmanned aerial vehicle piloted by ground-based radio equipment or an onboard flight control system. It possesses advantages such as small size, ease of use, low requirements for the operational environment, and strong battlefield survivability. Drones can be categorized into military and civilian applications. In the military field, drones are divided into reconnaissance aircraft and target drones; in the civilian field, drones can be integrated with various industries, expanding their applications.

[0003] To better adapt drones to outdoor operations and improve their endurance, the research and application of drone hangars are particularly important. After landing on the hangar's landing pad, the drone is typically moved into the hangar by a lifting device, where a robotic arm replaces the battery. During battery replacement, the robotic arm usually removes the battery from the drone and inserts it into the battery charging compartment inside the hangar for charging. Then, the robotic arm removes the fully charged spare battery from the battery storage compartment and installs it into the drone's battery box. Currently, drone hangars typically use air conditioning to supply cool air into the hangar, utilizing heat exchange between the cool air and the warm air inside to lower the hangar temperature, providing a more suitable storage and operating environment for the drone, and thus dissipating heat from the charging batteries and operating electronic components. For example, a drone nest disclosed in the existing patent publication number CN221367573U also uses an air conditioner to introduce cold air into the nest through the air duct to exchange heat with the hot air inside the nest, so as to reduce the temperature inside the nest and cool down the nest, drone and electronic appliances.

[0004] In summary, existing drone nests lower the internal temperature by exchanging heat between cool air and warm air inside the nest, thus cooling the electronic components and charging batteries. However, this cooling method has the following drawbacks: when the drone returns to the nest while the battery is charging and the electronic components are operating, opening the nest door causes the cool air inside to exchange heat with the warm air outside, raising the internal temperature and affecting the cooling effect on the electronic components and batteries. In other words, existing drone nests are affected by the influence of warm air outside the nest when cooling the electronic components and charging batteries. Summary of the Invention

[0005] One of the objectives of this invention is to provide a drone nest based on air-cooled circulating air duct heat dissipation, which aims to solve the technical problem that the heat dissipation effect of existing drone nests is affected by the hot air outside the nest when dissipating heat from the electronic appliances and charging batteries inside the nest.

[0006] To achieve the above objectives, this invention provides a drone housing based on air-cooled circulating air duct heat dissipation, comprising a casing, an air conditioning compartment, an electronic appliance compartment, a battery charging compartment, and a miniature air conditioner. The casing is provided with a door for opening or closing the casing. The electronic appliance compartment and the air conditioning compartment are both located within the casing. The battery charging compartment is used to charge the drone's battery. The miniature air conditioner is installed within the air conditioning compartment. The air outlet of the miniature air conditioner is sealed and connected to a cold air supply channel. The air outlet of the cold air supply channel is sealed and connected to a first cold air storage channel. The air outlet of the first cold air storage channel is sealed and connected to a second cold air storage channel. The air outlet of the second cold air storage channel is sealed and connected to the electronic appliance compartment. The electronic appliance compartment is sealed and connected. An air duct is provided on the electronic appliance compartment to guide the air passing through the electronic appliance compartment into the return air vent of the miniature air conditioner. The battery charging compartment is located on the upper surface of the first cold air storage channel. A ventilation slot communicating with the battery charging compartment is opened on the upper surface of the first cold air storage channel corresponding to the position of the battery charging compartment. The side of the battery charging compartment facing the door is closed, and the side of the battery charging compartment facing the miniature air conditioner is the opening of the battery charging compartment, so that the cold air in the first cold air storage channel can enter the battery charging compartment through the ventilation slot to exchange heat with the battery that is being charged, and then enter the return air vent of the miniature air conditioner from the opening.

[0007] The miniature air conditioner generates cool air, which flows sequentially through the supply air duct into the first and second cold air storage ducts and the electronics compartment, finally exiting through the air vent into the return air vent of the miniature air conditioner, thus circulating in a cycle. During this cycle, the cool air in the first cold air storage duct enters the battery charging compartment through the ventilation slots to exchange heat with the charging battery, carrying away the heat generated by the battery. The air, after heat exchange with the battery, then enters the return air vent of the miniature air conditioner from the battery charging compartment opening. Meanwhile, the cool air entering the electronics compartment from the second cold air storage duct directly exchanges heat with the electronic devices inside, carrying away their heat, thereby achieving the effect of cooling the electronic devices and the battery. Because the cool air is blown directly into the battery charging compartment and directly into the electronics compartment to exchange heat with the electronic devices, the cooling process for the electronic devices and the battery is protected from the influence of hot air from outside.

[0008] Furthermore, the ventilation slot is equipped with several booster fans, which are used to increase the flow of cold air entering the battery charging compartment.

[0009] Furthermore, the air inlet of the second cold storage air channel is smaller than the air outlet of the second cold storage air channel.

[0010] Furthermore, the air inlet of the cold air supply duct is larger than the air outlet of the cold air supply duct.

[0011] Furthermore, an inclined guide surface is provided at the top of the cold air supply duct, and the inclined guide surface is inclined downward from the air inlet of the cold air supply duct toward the air outlet of the cold air supply duct.

[0012] Furthermore, the air conditioning compartment and the electronic appliance compartment are spaced apart on the wall facing the door inside the housing. The cold air supply channel, the first cold air storage channel and the second cold air storage channel are all fixed to the bottom plate inside the housing. The cold air supply channel and the second cold air storage channel are arranged opposite to each other. The first cold air storage channel is horizontally perpendicular to the cold air supply channel or the second cold air storage channel.

[0013] Furthermore, the opening is located within the gap between the cold air supply channel and the second cold air storage channel.

[0014] Furthermore, the height of the second cold air storage channel is greater than the height of the first cold air storage channel.

[0015] Furthermore, the height of the air inlet of the cold air supply channel is greater than the height of the second cold air storage channel.

[0016] Furthermore, the battery charging compartment is connected to the outer wall of the first cold air storage channel by a heat conduction element.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention achieves heat dissipation for the electronic devices and batteries by directly blowing cold air into the battery charging compartment to exchange heat with the charging battery, and by directly blowing cold air into the electronics compartment to exchange heat with the electronic devices inside. This avoids the influence of hot air from outside the nest on the heat dissipation process, which would otherwise affect the heat dissipation effect. Compared to existing heat dissipation methods that exchange heat between cold air and the air inside the nest, the heat dissipation method of this invention does not weaken the heat dissipation effect of the electronic devices and batteries even when the nest door is opened, allowing the drone to return to the nest without restriction.

[0031] Please refer to Figure 1 - Figure 6 This invention provides a drone housing based on a wind-cooled circulating air duct 6 for heat dissipation, including a casing 1, an air conditioning compartment 2, an electronic appliance compartment 3, a battery charging compartment 4, a miniature air conditioner 5, and a wind-cooled circulating air duct 6. The wind-cooled circulating air duct 6 includes a cold air supply channel 60, a first cold air storage channel 61, and a second cold air storage channel 62.

[0032] Reference Figure 2 The front side of the housing 1 is provided with a door 10 for opening or closing the housing 1. The air conditioning compartment 2, the electronic appliance compartment 3, the battery charging compartment 4, the mini air conditioner 5, the cold air supply channel 60, the first cold air storage channel 61 and the second cold air storage channel 62 are all located inside the housing 1. The battery charging compartment 4 is used to charge the battery of the drone. The battery charging compartment 4 can adopt an existing structure, which will not be described here.

[0033] Reference Figure 1 , Figure 2 and Figure 3A miniature air conditioner 5 is installed inside the air conditioning compartment 2. The air outlet of the miniature air conditioner 5 is located at the lower end of the air conditioning compartment 2, and the return air outlet 51 of the miniature air conditioner is located at the upper end of the air conditioning compartment 2. The air outlet 50 of the miniature air conditioner is sealed and connected to the cold air supply channel 60. The air outlet of the cold air supply channel 60 is sealed and connected to the first cold air storage channel 61. The air outlet of the first cold air storage channel 61 is sealed and connected to the second cold air storage channel 62. The air outlet of the second cold air storage channel 62 is sealed and connected to the electronic appliance compartment 3. An air guide 30 is provided on the electronic appliance compartment 3. The air guide 30 is located on the top of the electronic appliance compartment 3 and is used to guide the air passing through the electronic appliance compartment 3 into the air outlet of the miniature air conditioner 5. The battery charging compartment 4 is fixed to the first cold air storage channel. On the upper surface of the first cold air storage channel 61, a ventilation slot 7 is provided corresponding to the position of the battery charging compartment 4 and communicates with the battery charging compartment 4. The side of the battery charging compartment 4 facing the door 10 is closed, and the side of the battery charging compartment 4 facing the mini air conditioner 5 is the opening 40 of the battery charging compartment 4, so that the cold air in the first cold air storage channel 61 can enter the battery charging compartment 4 through the ventilation slot 7 and exchange heat with the battery that is being charged, and then enter the air outlet of the mini air conditioner 5 through the opening 40 of the battery charging compartment 4.

[0034] Reference Figure 1 The miniature air conditioner 5 generates cold air, which flows through the cold air supply duct 60 into the first cold air storage duct 61, the second cold air storage duct 62, and the electronic appliance compartment 3, finally exiting through the air vent 30 into the air outlet of the miniature air conditioner 5, thus circulating in a cycle. During this cycle, the cold air in the first cold air storage duct 61 enters the battery charging compartment 4 through the ventilation slot 7 to exchange heat with the charging battery, carrying away the heat generated by the battery. The air after exchanging heat with the battery enters the return air vent 51 of the miniature air conditioner from the compartment opening 40 of the battery charging compartment 4. Meanwhile, the cold air entering the electronic appliance compartment 3 from the second cold air storage duct 62 directly exchanges heat with the electronic appliances inside the compartment, carrying away the heat from the electronic appliances, thereby achieving the effect of cooling the electronic appliances and the battery. Because the cold air is blown directly into the battery charging compartment 4 and directly into the electronic appliance compartment 3 to exchange heat with the electronic appliances, the process of cooling the electronic appliances and the battery is protected from the influence of hot air from outside.

[0035] In summary, the UAV nest based on the air-cooled circulating air duct 6 achieves heat dissipation for the electronic components and batteries by directly blowing cold air into the battery charging compartment 4 to exchange heat with the charging battery, and by directly blowing cold air into the electronic component compartment 3 to exchange heat with the electronic components inside the compartment 3. This avoids the influence of hot air outside the nest on the heat dissipation process, which would otherwise affect the heat dissipation effect. Compared to existing heat dissipation methods that exchange heat between cold air and the air inside the nest, the heat dissipation method of this invention does not weaken the heat dissipation effect of the electronic components and batteries even when the nest door 10 is opened, allowing the UAV to return to the nest without restriction.

[0036] In addition, several booster fans (not shown) are installed in the ventilation slot 7. For example, two booster fans are installed. The booster fans are used to increase the flow of cold air entering the battery charging compartment 4, thereby increasing the heat exchange efficiency between the cold air flow and the battery, and thus enhancing the heat dissipation effect of the battery.

[0037] In one embodiment, referring to Figure 1 and Figure 3 The electronic and electrical compartment 3, battery charging compartment 4, air conditioning compartment 2, cold air supply duct 60, first cold air storage duct 61, and second cold air storage duct 62 are arranged within the housing 1 as follows: the air conditioning compartment 2 and the electronic and electrical compartment 3 are spaced apart on the wall facing the door 10 within the housing 1. The cold air supply duct 60, the first cold air storage duct 61, and the second cold air storage duct 62 are all fixed to the bottom plate within the housing 1. The cold air supply duct 60 and the second cold air storage duct 62 are arranged opposite each other, and the first cold air storage duct 61 is horizontally perpendicular to either the cold air supply duct 60 or the second cold air storage duct 62. Those skilled in the art will understand that this layout fully utilizes the internal space of the housing, thereby effectively reducing the overall volume of the housing.

[0038] In one embodiment, referring to Figure 1 , Figure 4 and Figure 6 The air inlet of the cold air supply duct 60 is larger than the air outlet of the cold air supply duct 60, which increases the amount of cold air entering the cold air supply duct 60 from the air outlet of the miniature air conditioner 5. In addition, the height of the air inlet of the cold air supply duct 60 is greater than the height of the second cold air storage duct 62, further increasing the flow rate of the cold air stored in the cold air supply duct 60; the height of the second cold air storage duct 62 is greater than the height of the first cold air storage duct 61, increasing the flow area of ​​the cold air in the second cold air storage duct 62 and improving the heat dissipation effect.

[0039] Additionally, refer to Figure 1 and Figure 4An inclined guide surface 601 is provided at the top of the cold air supply duct 60, and the inclined guide surface 601 slopes downward from the air inlet of the cold air supply duct 60 towards the air outlet of the cold air supply duct 60. The inclined guide surface 601 mainly serves to guide the airflow, accelerating the flow of cold air in the cold air supply duct 60 to the first cold air storage duct 61, thereby improving the heat dissipation efficiency of the electronic appliances in the electronic appliance compartment 3 and the battery in the battery charging compartment 4. The inner wall surface of the inclined guide plate 602 at the top of the cold air supply duct 60 is configured as the aforementioned inclined guide surface 601.

[0040] In one embodiment, referring to Figure 4 , Figure 5 and Figure 6 The air inlet of the second cold air storage channel 62 is smaller than the air outlet of the second cold air storage channel 62. When the inner diameter of the air inlet of the second cold air storage channel 62 is small and the inner diameter of the air outlet of the second cold air storage channel 62 is large, the airflow flows out over a larger area of ​​the air outlet of the second cold air storage channel 62, the flow velocity will slow down, and the kinetic energy will be converted into static pressure energy, thereby increasing the static pressure at the air outlet of the second cold air storage channel 62, thus achieving the effect of noise reduction.

[0041] In one embodiment, referring to Figure 1 The opening of the battery charging compartment 4 is located within the gap between the cold air supply channel 60 and the second cold air storage channel 62. This prevents the airflow exiting from the opening of the battery charging compartment 4 from colliding with the inclined guide plate 602, thereby preventing the airflow after heat exchange from rebounding back into the battery charging compartment 4. In addition, a heat conduction element is connected to the outer wall of the first cold air storage channel 61. The heat on the battery charging compartment 4 can be conducted to the outer wall of the first cold air storage channel 61 through the heat conduction element. In this way, the heat on the battery charging compartment 4 can be exchanged with the outer wall of the first cold air storage channel 61 to cool down the battery charging compartment 4.

[0042] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
