Description

Technical Field

[0001] This utility model relates to a heat dissipation and airflow guiding structure, and more particularly to a heat dissipation and airflow guiding structure for a drone charging compartment. Background Technology

[0002] As a core component for centralized charging and storage of multiple batteries, the heat dissipation performance of the drone charging compartment directly affects battery charging efficiency, cycle life, and operational safety, playing a crucial role in multi-battery configurations such as consumer aerial photography drones and industrial inspection drones. With increasing demands for drone range, the number of batteries in a single charging compartment is gradually increasing. During charging, components such as batteries and charging contacts continuously generate heat. If this heat cannot be dissipated in time, it can easily lead to excessively high local temperatures within the compartment, causing problems such as limited battery charging and discharging rates, accelerated degradation of active materials, and even the risk of thermal runaway. Therefore, the rationality of the charging compartment's heat dissipation and airflow structure is essential to ensuring charging safety and equipment reliability.

[0003] Currently, most drone charging cases employ a cooling method that prioritizes passive heat dissipation, supplemented by simple active cooling. The core structure involves ventilation holes on the side walls of the case, creating natural airflow channels through the spacing between compartments. Some models also have a single axial fan installed on the top of the case to assist airflow. The main function of this existing technology is to remove some heat from the case through natural air convection or forced airflow in one direction. Compared to designs without a dedicated cooling structure, this can reduce the average temperature of the case to some extent and has the advantages of simple structure and low manufacturing cost. It can meet basic heat dissipation requirements in single- or dual-battery small-capacity charging case scenarios.

[0004] However, existing heat dissipation structures have significant structural flaws, making them ill-suited for the heat dissipation requirements of multi-compartment centralized charging. Limited by a single fan and simple airflow channels, airflow enters the compartment and tends to exit along the shortest path, failing to cover all charging compartments and heat-generating components such as contact points. This results in "heat dissipation dead zones" in areas like the middle compartments and contact points, leading to continuous heat accumulation. Furthermore, the existing structure lacks heat conduction enhancement design, preventing the rapid transfer of heat from localized heat sources like contact points and charging compartments to the airflow channels, further exacerbating localized overheating. These flaws not only result in low heat dissipation efficiency, failing to meet the heat dissipation requirements of simultaneous charging of multiple batteries, but also cause poor battery charging consistency due to uneven temperature distribution within the compartment, shortening the overall battery lifespan and even posing charging safety hazards due to localized high temperatures.

[0007] As a preferred technical solution of this utility model, it also includes an inverted plate, a partition, and a conical seat. An inverted plate is horizontally fixed in both charging slots of the charging base, with the opening of the inverted plate facing downwards. The lower part of the T-shaped groove is connected to the right part of the two inverted plates. Multiple partitions are horizontally spaced on the upper part of the inverted plate, which divide the charging slot into multiple horizontally distributed charging compartments. The number of charging compartments on the same side at the front and back is the same as the number of contact seats in the same charging slot, and each contact seat corresponds to a charging compartment. A conical seat is provided on the inverted plate corresponding to each charging compartment. Guide grooves are opened on the front and back sides of the upper part of the inverted plate near the bottom of the conical seat.

[0008] As a preferred technical solution of this utility model, air inlets are provided on both the front and rear sides of the left side of the charging base, and the air inlets connect the left space of the C-shaped plate with the left space of the L-shaped groove; the conical seat is truncated cone-shaped, and the small diameter end of the conical seat faces upward and the large diameter end is fixedly connected to the C-shaped plate; the guide groove extends along the length direction of the C-shaped plate, and the two ends of the guide groove are connected to the T-shaped groove and the air inlet respectively.

[0012] Beneficial effects: 1. When this utility model is in use, the airflow introduced by the intake fan is diverted by the guide shroud and T-shaped groove. Part of it carries away heat through the transverse airflow channel formed by the fins, and the other part enters the guide groove of the C-shaped plate.

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0022] A heat dissipation and airflow guiding structure for a drone charging compartment, such as Figure 1-6 As shown, the device includes a cabin 1, a shell 2, a charging base 21, a contact base 22, fins 23, an integrated module 3, an air intake base 4, an air intake fan 41, and an air exhaust fan 5. The shell 2 is fixed to the upper left of the cabin 1 by bolts. A control panel is embedded in the upper part of the shell 2. The control panel adopts a touch-screen LCD display panel structure. The panel surface integrates a charging start / stop button, a mode switching key, and a status display area. The status display area can display the charging progress, battery temperature, current and voltage parameters, and cooling fan operation status of each charging compartment in real time, so that the operator can intuitively grasp the equipment operation status. The shell 2 also has a control circuit board that is electrically connected to the control panel for receiving commands and providing signal feedback.

[0023] The cabin 1 has an inner groove, within which a mountain-shaped charging base 21 is fixed by bolts. The charging base 21 is made of aluminum alloy, providing both structural strength and thermal conductivity. It, together with the inner groove, forms two symmetrical charging slots for placing batteries to be charged. On both the front and rear sides of the charging base 21, multiple contact seats 22 are welded and fixed laterally at intervals. The contact seats 22 are made of copper alloy and have elastic conductive contacts on the top for contacting the battery electrodes to provide power. On both the front and rear sides of the charging base 21, there are also multiple spaced fins 23. The fins 23 are integrally formed with the charging base 21 and, together with the inner wall of the charging slot, form multiple vertically distributed horizontal airflow channels, which guide airflow across the surface of the charging base 21 to quickly remove heat.

[0024] The charging base 21 has an L-shaped groove 2100 inside, which serves as the main channel for airflow convergence and outflow. The right side of the cabin 1 is fixed with an air intake seat 4 by bolts. The left side of the air intake seat 4 has a T-shaped groove for initial airflow diversion. The right side of the air intake seat 4 has an air inlet, which serves as the entrance for external air. The air intake seat 4 has an air intake fan 41 fixed with a bracket inside, and the rear of the cabin 1 has an air outlet fan 5 fixed with a bracket. Both the air intake fan 41 and the air outlet fan 5 are electrically connected to the main control chip in the integrated module 3 through wires and are controlled by it. The left air outlet of the air intake fan 41 and the front air inlet of the air outlet fan 5 are both fixed with a flow guide shroud 51 by screws. The flow guide shroud 51 adopts an arc-shaped structure, which can guide the airflow in a directional direction and reduce airflow loss.

[0025] The right side of each fin 23 extends into the T-slot, connecting the transverse airflow channel with the T-slot. The left side of the air intake fan 41's shroud 51 connects to the T-slot, ensuring that all the airflow introduced by the air intake fan 41 enters the T-slot. The left side of the charging base 21 has a vent 2200, and the left side of each fin 23 extends into the vent 2200. The vent 2200 connects to the left side of the L-slot 2100, allowing the airflow in the transverse airflow channel to enter the L-slot 2100 through the vent 2200. The air exhaust fan 5's shroud 51 connects to the rear of the L-slot 2100, and the negative pressure of the air exhaust fan 5 discharges the airflow in the L-slot 2100 from the cabin 1.

[0026] Among them, such as Figure 3 and Figure 4 As shown, it also includes a C-shaped plate 6, a partition plate 62, and a conical seat 61. The two charging slots of the charging base 21 are each horizontally fixed with a C-shaped plate 6 by bolts. The C-shaped plate 6 is made of thermally conductive plastic, with its opening facing downwards, forming a closed airflow guiding space with the bottom of the charging slot. The lower part of the T-shaped groove connects to the right side of the two C-shaped plates 6, allowing some airflow from the T-shaped groove to enter the interior of the C-shaped plate 6. Multiple partition plates 62 are horizontally fixed to the upper part of the C-shaped plate 6 by welding at intervals. The partition plates 62 divide the charging slot into multiple horizontally distributed charging compartments, enabling independent placement and positioning of multiple batteries. The number of charging compartments on the same side (front and back) is the same as that of the same charging slot. The number of contact seats 22 in the battery compartment is consistent, and each contact seat 22 corresponds to a charging compartment, ensuring that the battery in each compartment can make precise contact with the contact seat 22. A conical seat 61 is fixedly installed on the inverted plate 6 at each charging compartment by bolts. The conical seat 61 is truncated cone-shaped, with the small diameter end facing upward and the large diameter end fixedly connected to the inverted plate 6. It can guide and position the battery placed in the charging compartment, avoiding poor contact caused by battery misalignment. The front and rear sides of the upper part of the inverted plate 6 near the bottom of the conical seat 61 are provided with airflow channels 6200, which can guide airflow through the bottom of the battery and enhance the battery heat dissipation effect.

[0027] The charging base 21 has air inlets 6100 on both the front and rear sides of the left side. The air inlets 6100 connect the left space of the C-shaped plate 6 with the left space of the L-shaped groove 2100, so that the airflow in the C-shaped plate 6 can enter the L-shaped groove 2100 through the air inlets 6100. The guide groove 6200 extends along the length of the C-shaped plate 6 and its two ends are connected to the T-shaped groove and the air inlets 6100 respectively, forming a complete airflow path through the C-shaped plate 6.

[0028] An integrated module 3 is fixedly installed at the upper rear of the cabin 1 by screws. The integrated module 3 encapsulates a main control chip, a charging management module, a temperature monitoring module, and a power conversion module. Its operating logic is as follows: the temperature monitoring module collects the temperature signal of key areas inside the cabin 1 in real time and transmits it to the main control chip. The main control chip, in conjunction with the operation instructions of the control panel, adjusts the charging current of each contact seat 22 through the charging management module, and controls the start, stop and speed of the intake fan 41 and the exhaust fan 5 according to the temperature data. The power conversion module converts the external input power into an adaptive voltage to power the entire device.

[0029] In addition, such as Figure 3 , Figure 4 and Figure 6 As shown, it also includes a heat-conducting plate 221 and a heat-conducting plate 63. The lower part of the contact base 22 is embedded with a heat-conducting plate 221. The heat-conducting plate 221 is made of copper and has excellent thermal conductivity. Its lower part extends into a similar airflow channel, which can quickly conduct the heat generated by the contact base 22 during charging to the airflow channel and be carried away by the airflow. On the side of the charging slot away from the fins 23 in the charging slot of the charging base 21, there are multiple heat-conducting plates 63 that are horizontally spaced and vertically bolted. The heat-conducting plates 63 are also made of thermally conductive material. Their number is consistent with the number of charging compartments in the same charging slot and corresponds one-to-one. They can fit against the side wall of the battery and conduct the heat generated by the battery to themselves. Each heat-conducting plate 63 has a vertical notch, which can guide the airflow direction, reduce its own weight, and not affect the heat conduction. Its lower end extends into a similar guide groove 6200, so that the heat conducted to the heat-conducting plate 63 can be quickly transferred to the airflow in the guide groove 6200.

[0030] like Figure 1 As shown, multiple fasteners are provided on both the front and rear sides of the upper part of the chamber 1 for installing the cover by means of a snap-fit. When customizing the chamber 1, corresponding fasteners and covers that are compatible with them are set. The edge of the cover can be snapped into the fastener for quick fixation. After installation, it can cover and seal the upper part of the charging chamber and each charging compartment, which can prevent external dust and moisture from falling directly into the charging compartment and the contact area of ​​the contact seat 22, and prevent foreign objects from accidentally entering during charging and causing short circuit risk. At the same time, it does not affect the normal airflow of heat dissipation inside the chamber 1, and the snap-fit ​​connection facilitates the quick disassembly of the cover, providing convenience for battery placement and maintenance of internal components.

[0031] In addition, to further reduce the interference of external impurities on the charging components, such as Figure 1 As shown, it also includes a filter screen 7. The right air inlet of the air inlet seat 4 is provided with an installation groove, in which the filter screen 7 is inserted. The filter screen 7 adopts a multi-layer composite structure, with an outer layer of nylon mesh and an inner layer of HEPA filter screen, which can effectively filter dust, impurities and other contaminants in the air, preventing impurities from entering the interior of the chamber 1 and adhering to components such as the contact seat 22 and the fan, thus affecting the stability of equipment operation and heat dissipation efficiency. The plug-in design also facilitates the disassembly, cleaning and replacement of the filter screen 7.

[0032] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
