Description

Technical Field

[0001] This utility model relates to the field of drone detection technology, specifically to a housing suitable for drone detection devices, used to encapsulate drone detection devices, while achieving efficient passive heat dissipation and reliable sealing and waterproofing, ensuring stable operation of the device in complex outdoor environments. Background Technology

[0002] With the rapid development of drone technology, drones are widely used in civilian and commercial fields. However, security issues such as unauthorized flights, privacy violations, and flight interference have also become prominent, making the demand for drone detection devices increasingly urgent. Drone detection devices typically need to operate continuously in complex outdoor environments with high temperatures, rain, and humidity. However, existing housings have significant shortcomings: Poor heat dissipation: The electronic components inside the detection device, such as processors and power modules, generate a lot of heat during operation. If this heat cannot be dissipated in time, the internal temperature will soar, reducing the stability and detection accuracy of the electronic components and significantly shortening their lifespan. Some existing housings use "active fan cooling," but this requires additional drive components, which not only increases power consumption and the risk of failure, but also makes it easy for dust and moisture to be drawn in during fan operation, compromising the sealing performance. Insufficient sealing and waterproofing: Outdoor rainwater and moisture can easily penetrate the interior through the housing gaps, causing short circuits and corrosion of electronic components, severely reducing the reliability and lifespan of the device. In addition, some housings have unreasonable heat conduction path designs, making it difficult for heat to be quickly transferred to the outside for dissipation even when using heat-conducting materials. Therefore, there is an urgent need for a drone detection device housing that can efficiently dissipate heat without additional drive components and has excellent sealing and waterproofing performance.

[0031] Utility Model Technical Solution / Principle:

[0032] This utility model discloses a housing suitable for drone detection devices. The core of the design lies in achieving reliable protection and efficient heat dissipation in outdoor environments by optimizing the sealing structure and passive heat dissipation path. The specific technical solution is as follows:

[0033] The housing mainly comprises a sealed waterproof enclosure S4 and a passive heat dissipation assembly. The sealed waterproof enclosure S4 is a hollow enclosure structure with an opening at one end, and a sealable cover S8 is provided at the opening end. A sealing element S9, specifically an elastic rubber sealing ring, is provided at the contact point between the cover S8 and the wall of the sealed waterproof enclosure S4. A matching sealing groove is provided on the inner side of the cover S8, and the sealing ring is embedded in the groove. When closed, compression achieves a complete seal, preventing rainwater and moisture from entering. A drone detection device is installed inside the sealed waterproof enclosure S4, and a pre-installed installation gap is provided between the detection device and the inner wall S1 of the enclosure to provide space for the heat dissipation assembly. The passive heat dissipation assembly includes a heat-conducting component and heat dissipation fins S7, forming a heat dissipation path of "detection device → heat-conducting component → enclosure → heat dissipation fins → outside". The heat-conducting component is located within the installation gap, with one side tightly attached to the UAV detection device and the other side tightly connected to the inner wall S1 of the sealed waterproof enclosure S4. It can be implemented in two ways: ① a combination of a heat pipe S5 and copper sheet S2, with copper sheets S2 connected to both ends of the heat pipe. The copper sheets S2 are fixed to the detection device and the inner wall S1 of the enclosure respectively using fasteners; ② an aluminum heat-conducting plate or graphene heat-conducting sheet, with thermal grease applied to the contact surface with the detection device to reduce thermal resistance. The heat dissipation fins S7 are fixed to the outer wall of the sealed waterproof enclosure S4, evenly distributed along the outer wall, preferably integrally formed with the enclosure; their quantity is 5-20 pieces, with an adjacent spacing of 5-10mm, a thickness of 1-3mm, and a height of 10-30mm, increasing the heat dissipation area to accelerate heat dissipation. The auxiliary structure, a sealed and waterproof enclosure S4, is made of high thermal conductivity aluminum alloy, balancing structural strength and thermal conductivity. The enclosure wall has a signal transmission interface hole S6 with a built-in waterproof connector. A sealing ring is installed between the connector and the hole wall to ensure the waterproofness of the cable exit point. The UAV detection device is installed on the aluminum plate S3 inside the enclosure with fasteners. The aluminum plate S3 is then fixed to the inner wall S1 of the enclosure with fasteners. Thermally conductive silicone pads are filled between the aluminum plate S3 and the inner wall S1 to enhance heat dissipation and provide cushioning.

[0034] The present invention will be described in detail below with reference to specific structural parameters. The following settings for size, shape, model, etc. are all specific embodiments of this application and should not be construed as limiting the technical solution of this application.

[0035] The sealed waterproof enclosure S4 is made of high thermal conductivity aluminum alloy, and has a hollow cuboid structure with a length of 300mm, a width of 200mm, and a height of 150mm. One end is open, and the opening size matches the enclosure lid. The enclosure lid S8 is a plate-like structure of the same material, with an 8mm wide and 5mm deep sealing groove on the inside. A 6mm diameter circular elastic rubber sealing ring S9 is embedded in the groove. When closed, the sealing ring is compressed by 30%, achieving IP65 waterproof rating. The drone detection device is mounted on a 2mm thick aluminum plate S3 using M3 screws. The dimensions of the aluminum plate S3 match the base of the detection device. The aluminum plate S3 is fixed to the inner wall S1 of the sealed waterproof enclosure S4 using four M4 screws. A 1mm thick thermally conductive silicone sheet with a thermal conductivity of 3W / m·K is filled between the aluminum plate S3 and the inner wall S1 to fill the assembly gap and enhance thermal conductivity. The passive heat dissipation components employ a combined structure: 2-4 copper heat pipes (S5) with a diameter of 6mm, each end welded with a 1mm thick copper sheet (S2), measuring 30mm x 30mm. One copper sheet is fixed to the processor heatsink of the detection device using an M2 screw, with the contact surface coated with 0.1mm thick thermal grease. The other copper sheet is fixed to the corresponding position on the inner wall of the enclosure (S1) using an M3 screw. The outer wall of the enclosure has 12 integrally formed heat dissipation fins (S7), each 2mm thick and 20mm high, with an 8mm spacing between adjacent fins, evenly distributed along the length of the enclosure, providing a total heat dissipation area of ​​approximately 0.15㎡. For waterproofing, the enclosure sidewall has three 20mm diameter interface holes (S6) for various antenna heads. Each hole houses a PG16 waterproof connector, with a heat-resistant rubber sealing ring (60 Shore A hardness) embedded between the connector and the hole wall. After the antenna head passes through the connector, it is secured with the connector's built-in clamping nut, ensuring an IP67 waterproof rating at the interface.

[0036] Working process: When the detection device is working, the heat generated by the processor and other heat-generating components is transferred partly through "copper plate S2 → heat pipe S5 → copper plate S2 → inner wall of the box S1" and partly through "aluminum plate S3 → thermally conductive silicone sheet → inner wall of the box S1". The heat is conducted through the aluminum alloy box to the heat dissipation fins S7 on the outer wall and finally dissipated to the outside through natural convection, keeping the temperature inside the box below 50°C. At the same time, the various sealing structures effectively block rainwater and moisture, ensuring the stable operation of the detection device in complex outdoor environments.
