Description

Technical Field

[0001] This utility model belongs to the field of battery heat dissipation technology, specifically, it relates to a wind-cooled heat dissipation structure for drone batteries. Background Technology

[0002] With the development of technology, drones are widely used in various fields such as agriculture, construction, and tourism. Batteries, as a crucial component of drones, provide them with an energy source. Currently, there are two power supply methods for drones and batteries: battery swapping and charging. In battery swapping, the battery and drone are detachable, allowing operators to directly replace a depleted battery with a fully charged one, eliminating the need to wait for charging and meeting the operator's need for rapid deployment.

[0003] Currently, drone batteries generate a lot of heat when they are disassembled and charged. In scenarios where drones are used extensively, the demand for battery charging is concentrated, generating even more heat. If the heat cannot be dissipated in time, it will accelerate battery aging, shorten its lifespan, and in severe cases, even cause the battery to bulge, leak, catch fire, or even explode, resulting in not only property damage but also safety hazards. Utility Model Content

[0004] To address the technical problem of heat accumulation when charging multiple drone batteries simultaneously in the prior art, this invention provides a drone battery air-cooling heat dissipation structure.

[0005] The objective of this utility model can be achieved through the following technical solutions: A drone battery air-cooling structure includes a heat dissipation box; three rows of evenly distributed heat dissipation slots are formed on both sides of the heat dissipation box; the heat dissipation slots are straight grooves; a first protrusion is fixed to both sides of the inner side wall of the heat dissipation box; a second protrusion is fixed to both ends of the inner side wall of the heat dissipation box; and evenly distributed support protrusions are fixed to the bottom of the heat dissipation box, all of which are located at the intersection of the bottom extension lines of the first and second protrusions, so that the drone battery forms a heat dissipation channel when placed on the support protrusions; and a heat dissipation mechanism is provided on the outside of the heat dissipation box.

[0006] Furthermore, both the first and second protrusions are L-shaped structures arranged inside the heat sink, and both the upper and lower ends are arc-shaped structures; both the first and second protrusions are located in the middle of the heat dissipation channel.

[0007] Furthermore, the heat dissipation mechanism includes a first straight plate attached to both sides of the outside of the heat dissipation box; a second straight plate attached to one end face of the outside of the heat dissipation box; two first straight plates located at opposite ends of the second straight plate; air chambers are provided inside both the first and second straight plates, and the connection between the two first straight plates and the second straight plate always maintains communication between the air chambers.

[0008] Furthermore, the ends of the first and second straight plates are connected by flexible ribs.

[0009] Furthermore, the first straight plate has a plug that corresponds to the heat dissipation channel on one side of the heat dissipation box, and the shape of the plug matches the shape of the heat dissipation channel; the first straight plate has an exhaust port at the position corresponding to the plug; and the second straight plate has a connector for conveying cold air fixed at the center position.

[0010] Furthermore, the heat dissipation mechanism includes multiple cooling fans magnetically attached to the outer wall of the heat dissipation box.

[0011] Furthermore, a limiting block is fixed to the side of the cooling fan near the heat sink, and the limiting block is located at the four corners of the cooling fan; the limiting block is embedded in the corresponding heat dissipation channel.

[0012] The beneficial effects of this utility model are: 1. This utility model first places multiple drone batteries inside the heat dissipation box from top to bottom, automatically connecting the charging interface and the charging cable. Then, the air chambers inside the first and second straight plates are connected to the cold air blower using connectors and hoses. The cold air blower continuously delivers cold air into the air chambers, and the cold air is delivered into the heat dissipation box through evenly arranged exhaust ports (heat dissipation channels). The cold air continuously exchanges heat with the sides of the drone batteries. Afterward, some of the cold air flows to the upper part of the drone batteries, and some flows to the lower part of the drone batteries. The cold air entering the lower part then flows along the heat dissipation channel formed by the bottom wall of the drone batteries and the supporting protrusions, dissipating heat from all directions for the drone batteries and ensuring that the heat dissipation needs can be met in a timely manner when multiple drone batteries are charging.

[0013] 2. When installing the first and second straight plates, the first straight plate can be fixed to the side wall of the heat dissipation box by inserting the plug into the heat dissipation channel, thus completing the fixing work. The installation is convenient and easy to carry.

[0014] 3. This utility model directly connects the cooling fan to the heat dissipation box, which can provide heat dissipation for drone batteries during simple outdoor operations. By drawing air into the heat dissipation channel formed by the first protrusion, the second protrusion, and the supporting protrusion, the airflow speed is accelerated, allowing the heat accumulated inside the heat dissipation box to diffuse to the outside, thus achieving a heat dissipation effect. It is suitable for charging scenarios with a small number of drone batteries and is more convenient to carry. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to it again. Figure 1 and Figure 6 As shown, a first straight plate 6 is attached to both sides of the exterior of the heat sink 1, and the length of the first straight plate 6 is equal to the length of the heat sink 1; a second straight plate 7 is attached to one end face of the exterior of the heat sink 1, and the length of the second straight plate 7 is equal to the width of the heat sink 1; the two first straight plates 6 are located at opposite ends of the second straight plate 7, and the ends of the first straight plate 6 and the second straight plate 7 are connected by a flexible rib 9; a plug 10 corresponding to the heat dissipation channel is fixed to the side of the first straight plate 6 that is attached to the heat sink 1, and the shape of the plug 10 matches the shape of the heat dissipation channel.

[0019] Please refer to it again. Figure 6 As shown, both the first straight plate 6 and the second straight plate 7 have air chambers 8 inside, and the air chambers 8 are always connected at the connection points between the two first straight plates 6 and the flexible ribs 9 of the second straight plate 7; a connector 12 is fixedly connected to the center of the second straight plate 7, which is used to connect a cold air blower and deliver cold air into the connector 12; an exhaust port 11 is opened on the first straight plate 6 corresponding to the position of the insert block 10, and the cold air is delivered to the exhaust port 11 through the air chambers 8, and then delivered from the exhaust port 11 into the interior of the heat dissipation box 1 to cool the drone battery.

[0020] To facilitate understanding of the above technical solution of Embodiment 1 of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below: First, multiple drone batteries are placed inside the heat dissipation box 1 from top to bottom, and the charging interface and charging cable are automatically connected. Then, the air chamber 8 inside the first straight plate 6 and the second straight plate 7 are connected to the cold air fan using the connector 12 and the hose. The cold air fan continuously delivers cold air into the air chamber 8, and the cold air is delivered into the heat dissipation box 1 through the evenly arranged exhaust ports 11 (heat dissipation channels). The cold air continuously exchanges heat with the sides of the drone batteries. Then, part of the cold air is directed to the upper part of the drone batteries and part is directed to the lower part of the drone batteries.

[0023] In this embodiment, by directly connecting the cooling fan 13 to the heat dissipation box 1 during specific operations, the drone battery can be cooled during simple outdoor operations. By drawing air into the heat dissipation channel formed by the first protrusion 3, the second protrusion 4, and the supporting protrusion 5, the airflow speed is accelerated, allowing the heat accumulated inside the heat dissipation box 1 to diffuse to the outside, thus achieving a heat dissipation effect. This is suitable for charging scenarios with a small number of drone batteries and is more convenient to carry.
