Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle nest based on air-cooled circulating air duct heat dissipation. Background Art

[0002] A drone is an unmanned aircraft that is piloted by radio ground equipment or an onboard flight control system. It has the advantages of small size, easy use, low requirements for the combat environment, and strong battlefield survivability. Drones can be divided into military and civilian applications. In the military, drones are divided into reconnaissance aircraft and target aircraft; in the civilian application, drones can be combined with various industries to expand the use of drones themselves.

[0003] In order to make drones better adapt to outdoor operations and improve the endurance of drones, the research and development and application of drone nests are particularly important. Among them, after the drone lands on the apron of the nest, the apron is usually moved to the nest by a lifting device, and then the battery is replaced by a robotic arm. When replacing the battery of a drone, the battery on the drone is usually removed by a robotic arm, inserted into the battery charging compartment in the nest for charging, and then the fully charged spare battery in the battery storage compartment is taken out by the robotic arm and installed in the battery box of the drone. At present, the drone nest usually sends cold air into the drone nest through air conditioning, and uses the cold air to exchange heat with the hot air in the nest to reduce the temperature in the nest, providing a more suitable storage and working environment for the drone, thereby dissipating the heat of the charging batteries and working electronic appliances in the nest. For example, a drone nest disclosed in the existing patent announcement number CN221367573U also uses air conditioning to pass cold air into the nest through the air duct to exchange heat with the hot air in the nest, so as to reduce the temperature in the nest and cool the nest, drone and electronic appliances.

[0004] In summary, the existing drone nest exchanges heat with the hot air in the nest daily to reduce the temperature in the nest, thereby achieving the effect of cooling the electronic appliances working in the nest and the batteries being charged. However, this heat dissipation method has the following defects: when the nest is just in the process of charging the battery and the electronic appliances are in working condition, if the drone just returns to the nest at this time, then after the hatch of the nest is opened, the cold air in the nest will exchange heat with the hot air outside the nest, causing the temperature in the nest to rise, thereby affecting the heat dissipation effect of the electronic appliances and batteries in the nest. That is, when the existing drone nest dissipates heat for the electronic appliances working in the nest and the batteries being charged, it is affected by the hot air outside the nest and the heat dissipation effect is affected. Summary of the invention

[0005] One of the purposes of the present invention is to provide a drone nest based on air-cooled circulating duct heat dissipation, which aims to solve the technical problem that the existing drone nest is affected by the hot air outside the nest when dissipating heat for electronic appliances working in the nest and batteries being charged, thereby affecting the heat dissipation effect.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a drone nest based on air-cooled circulating air duct heat dissipation, including a casing, an air-conditioning compartment, an electronic and electrical compartment, a battery charging compartment and a micro air-conditioner, the casing is provided with a hatch for opening or closing the casing, the electronic and electrical compartment and the air-conditioning compartment are both arranged in the casing, the battery charging compartment is used to charge the battery of the drone, the micro air-conditioner is installed in the air-conditioning compartment, the air supply port of the micro air-conditioner is sealed and connected with a cold air supply channel, the air outlet of the cold air supply channel is sealed and connected with a first cold air storage channel, the air outlet of the first cold air storage channel is sealed and connected with a second cold air storage channel, the air outlet of the second cold air storage channel is sealed and connected with the electronic and electrical compartment The electronic appliance compartment is sealed and connected, an air guide port is provided on the electronic appliance compartment, and the air guide port is used to guide the air passing through the electronic appliance compartment into the return air port of the micro air conditioner; the battery charging compartment is arranged on the upper surface of the first cold air storage channel, and a ventilation groove connected to 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 battery charging compartment is closed on the side facing the hatch, and the side of the battery charging compartment facing the micro air conditioner is the compartment opening of the battery charging compartment, so that the cold air in the first cold air storage channel can enter the battery charging compartment from the ventilation groove, exchange heat with the battery being charged, and then enter the return air port of the micro air conditioner from the compartment opening.

[0007] The micro air conditioner generates cold air during operation, and the cold air enters the first cold air storage channel, the second cold air storage channel and the electronic appliance compartment in turn through the cold air supply channel, and finally enters the return air outlet of the micro air conditioner from the air guide port, thus circulating. During this cycle, the cold air in the first cold air storage channel enters the battery charging compartment through the ventilation slot to exchange heat with the battery being charged, taking away the heat generated by the battery, and the air after heat exchange with the battery enters the return air outlet of the micro air conditioner from the compartment port of the battery charging compartment; and the cold air entering the electronic appliance compartment from the second cold air storage channel directly exchanges heat with the electronic appliances in the appliance compartment, taking away the heat of the electronic appliances, thereby achieving the effect of dissipating heat from the electronic appliances and batteries. Since the cold air is blown directly into the battery charging compartment to exchange heat with the battery being charged, and the cold air is blown directly into the electronic appliance compartment to exchange heat with the electronic appliances, it can be avoided that the heat dissipation of the electronic appliances and batteries is not affected by the hot air outside the nest.

[0008] Furthermore, a plurality of booster fans are arranged in the ventilation slot, and the plurality of booster fans are used to increase the flow of cold air entering the battery charging compartment.

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

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

[0031] Please refer to Figure 1 - Figure 6 The present invention provides a drone nest based on a cooling circulation duct 6 for heat dissipation, comprising a housing 1, an air conditioning compartment 2, an electronic appliance compartment 3, a battery charging compartment 4, a mini air conditioner 5 and a cooling circulation duct 6. The cooling circulation duct 6 comprises 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 A door 10 for opening or closing the casing 1 is provided on the front side of the casing 1; the air conditioning compartment 2, the electronic appliance compartment 3, the battery charging compartment 4, the miniature 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 arranged in the casing 1; the battery charging compartment 4 is used to charge the battery of the drone, and the battery charging compartment 4 can adopt the existing structure, which is not explained here.

[0033] Reference Figure 1 , Figure 2 and Figure 3The micro air conditioner 5 is installed in the air conditioning compartment 2, the air supply port of the micro air conditioner 5 is located at the lower end of the air conditioning compartment 2, and the return air port 51 of the micro air conditioner is located at the upper end of the air conditioning compartment 2. The air supply port 50 of the micro air conditioner is sealed and connected with the cold air supply channel 60, the air outlet of the cold air supply channel 60 is sealed and connected with the first cold air storage channel 61, the air outlet of the first cold air storage channel 61 is sealed and connected with the second cold air storage channel 62, and the air outlet of the second cold air storage channel 62 is sealed and connected with the electronic and electrical compartment 3; the electronic and electrical compartment 3 is provided with an air guide port 30, the air guide port 30 is provided at the top of the electronic and electrical compartment 3, and the air guide port 30 is used to guide the air passing through the electronic and electrical compartment 3 into the air outlet of the micro air conditioner 5; the battery charging compartment 4 is fixed on the first cold air storage channel 61, a ventilation slot 7 communicating with the battery charging compartment 4 is provided on the upper surface of the first cold air storage channel 61 at a position corresponding to the battery charging compartment 4, the battery charging compartment 4 is closed on the side facing the hatch 10, and the side of the battery charging compartment 4 facing the mini air conditioner 5 is a hatch 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 from the ventilation slot 7 to exchange heat with the battery being charged, and then enter the air outlet of the mini air conditioner 5 from the hatch 40 of the battery charging compartment 4.

[0034] Reference Figure 1 The micro air conditioner 5 generates cold air when it is working. The cold air enters the first cold air storage channel 61, the second cold air storage channel 62 and the electronic appliance compartment 3 in sequence through the cold air supply channel 60, and finally enters the air outlet of the micro air conditioner 5 from the air guide port 30, so as to circulate. In this circulation process, the cold air in the first cold air storage channel 61 enters the battery charging compartment 4 through the ventilation slot 7 to exchange heat with the battery being charged, taking away the heat generated by the battery, and the air after heat exchange with the battery enters the return air port 51 of the micro air conditioner from the compartment port 40 of the battery charging compartment 4; and the cold air entering the electronic appliance compartment 3 from the second cold air storage channel 62 directly exchanges heat with the electronic appliances in the appliance compartment, taking away the heat of the electronic appliances, thereby achieving the effect of heat dissipation of the electronic appliances and batteries. Since the cold air is directly blown into the battery charging compartment 4 to exchange heat with the battery being charged, and the cold air is directly blown into the electronic appliance compartment 3 to exchange heat with the electronic appliances, it can be avoided that the heat dissipation of the electronic appliances and batteries is not affected by the hot air outside the nest.

[0035] In summary, the drone nest based on the air-cooled circulating air duct 6 of the present invention achieves the purpose of cooling the electronic appliances and batteries by blowing cold air directly into the battery charging compartment 4 to exchange heat with the battery being charged, and by blowing cold air directly into the electronic appliance compartment 3 to exchange heat with the electronic appliances in the electronic appliance compartment 3, thereby avoiding the heat dissipation effect being affected by the hot air outside the nest during the heat dissipation of the electronic appliances and batteries. Compared with the existing heat dissipation method of exchanging heat between cold air and the air in the nest, the heat dissipation method of the present invention will not weaken the heat dissipation effect of the electronic appliances and batteries even if the hatch 10 of the nest is opened, so that the timing of the drone returning to the nest is not restricted.

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

[0037] In one embodiment, referring to Figure 1 and Figure 3 , the layout of the electronic appliance compartment 3, the battery charging compartment 4, the air conditioning compartment 2, the cold air supply channel 60, the first cold air storage channel 61 and the second cold air storage channel 62 in the housing 1 is as follows: the air conditioning compartment 2 and the electronic appliance compartment 3 are arranged at intervals on the wall of the housing 1 facing the cabin door 10, the cold air supply channel 60, the first cold air storage channel 61 and the second cold air storage channel 62 are all fixed on the bottom plate in the housing 1, the cold air supply channel 60 and the second cold air storage channel 62 are arranged opposite to each other, and the first cold air storage channel 61 is horizontally perpendicular to the cold air supply channel 60 or the second cold air storage channel 62. It can be understood by those skilled in the art that the above-mentioned layout structure makes full use of the space inside the machine nest, thereby effectively reducing the volume of the entire machine nest.

[0038] In one embodiment, referring to Figure 1 , Figure 4 and Figure 6 The air inlet of the cold air supply channel 60 is larger than the air outlet of the cold air supply channel 60, so that the cold air entering the cold air supply channel 60 from the air supply port of the mini air conditioner 5 can be increased. In addition, the height of the air inlet of the cold air supply channel 60 is greater than the height of the second cold air storage channel 62, which further increases the flow rate of cold air stored in the cold air supply channel 60; the height of the second cold air storage channel 62 is greater than the height of the first cold air storage channel 61, which increases the flow area of ​​cold air in the second cold air storage channel 62 and improves the heat dissipation effect.

[0039] In addition, refer to Figure 1 and Figure 4The top of the cold air supply channel 60 is provided with an inclined guide surface 601, which is inclined downward from the air inlet of the cold air supply channel 60 to the air outlet of the cold air supply channel 60. The inclined guide surface 601 mainly plays the role of guiding, accelerating the flow of cold air in the cold air supply channel 60 to the first cold air storage channel 61, and improving the heat dissipation efficiency of the electronic appliances in the electronic appliance compartment 3 and the batteries in the battery charging compartment 4. Among them, the inner wall surface of the inclined guide plate 602 at the top of the cold air supply channel 60 is configured as the above-mentioned 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 port of the second cold air storage channel 62 is small and the inner diameter of the air outlet port of the second cold air storage channel 62 is large, the airflow flows out over a larger area of ​​the air outlet port 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 of the air outlet of the second cold air storage channel 62, thereby 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 spacing between the cold air supply channel 60 and the second cold air storage channel 62, so that the airflow discharged from the opening of the battery charging compartment 4 can be prevented from colliding with the inclined guide plate 602, thereby preventing the airflow after heat exchange from rebounding and flowing back into the battery charging compartment 4. In addition, the battery charging compartment 4 and the outer wall of the first cold air storage channel 61 are connected with a heat conduction member, and 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 member, so that the heat on the battery charging compartment 4 and the outer wall of the first cold air storage channel 61 can be heat exchanged to cool the battery charging compartment 4.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
