Description

Technical Field

[0001] This utility model belongs to the field of circuit board heat dissipation technology, and in particular relates to a high-efficiency heat dissipation shell for a two-way wireless image transmission circuit board. Background Technology

[0002] The two-way wireless video transmission device is a wireless transceiver specifically designed for automobiles, robots, drones, and other applications. Utilizing advanced multi-carrier modulation technology for complex ground environments, it boasts strong anti-interference and penetration capabilities, enabling the transmission of high-definition, stable, low-latency, real-time video image signals while in motion. Suitable for complex ground environments, the two-way wireless video transmission device can be mounted on vehicles, firefighting robots, public security robots, drones, and other facilities.

[0003] Under the premise of achieving the same function, the smaller and lighter the device, the stronger its adaptability to the environment, and the more application areas and scenarios it can be used in. Wireless image transmission transceivers are power-consuming devices that generate heat. Ordinary heat dissipation shells are either too large and heavy to meet the requirements of small size and light weight for two-way wireless image transmission devices, or they have low heat dissipation efficiency and cannot dissipate heat quickly, causing the module temperature to be too high, affecting transmission efficiency or even burning out the device. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heat dissipation housing for a two-way wireless image transmission circuit board to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the specific technical solution of the high-efficiency heat dissipation shell for a two-way wireless image transmission circuit board of this utility model is as follows:

[0006] A high-efficiency heat dissipation housing for a two-way wireless image transmission circuit board includes a square housing that matches the size of the circuit board. The housing comprises an upper shell and a lower shell, with a cavity between the upper and lower shells to accommodate the circuit board. The circuit board is tightly fitted between the upper and lower shells and transfers heat through them. A fan is installed at the center of the upper shell, and a multi-channel structure is formed on both sides of the fan. Multiple heat dissipation channels are provided on the lower half of the lower shell. The multi-channel structure on the upper shell and below the fan has multiple through-holes for dissipating heat. These through-holes are used to introduce the fan's airflow into the heat dissipation channels of the lower shell, thereby removing heat from the wireless image transmission module and reducing the weight of the housing.

[0007] Furthermore, the multi-air duct structure includes multiple baffles, and air ducts are formed between the baffles. The air ducts include horizontal air ducts and vertical air ducts. The horizontal air ducts are arranged on both sides of the fan to direct the fan's airflow to both sides. The vertical air ducts are arranged at the upper and lower ends of the horizontal air ducts to diffuse the fan's airflow to the upper and lower ends of the housing.

[0008] Furthermore, the baffle of the vertical air duct is designed with an arc near the horizontal air duct to guide the airflow. The arcs of the baffles on the left and right sides are opposite, with the center of the arc facing the middle of the housing, thus realizing the structure of guiding the airflow from the center to both sides of the fan.

[0009] Furthermore, the lower shell has multiple mounting holes, and screws pass through the mounting holes on the lower shell and the fixing holes on the inner side of the upper shell to fix the upper shell and the lower shell together.

[0010] Furthermore, the upper part of the housing is a mounting position for a two-way wireless image transmission circuit board, and the upper part of the lower housing has multiple grooves on its surface to reduce the overall weight of the housing.

[0011] Furthermore, the heat dissipation holes are arranged in the air ducts on the left and right sides of the lower half of the housing, with multiple holes arranged in one air duct.

[0012] Furthermore, the upper end of the housing has antenna mounting threads on both sides for mounting the antenna.

[0013] Furthermore, the lower end of the housing has multiple interface grooves for housing multiple interfaces of the bidirectional wireless image transmission circuit board.

[0014] Furthermore, the casing is made of a metal material with high thermal conductivity.

[0015] The high-efficiency heat dissipation housing of the bidirectional wireless image transmission circuit board of this utility model has the following advantages: The high-efficiency heat dissipation housing of the bidirectional wireless image transmission circuit board of this utility model is provided with a fan and air duct on the upper shell to improve heat dissipation efficiency. At the same time, heat dissipation through holes are provided in the air duct to introduce the airflow of the fan into the heat dissipation air duct of the lower shell. The heat of the wireless image transmission module is carried away through the heat dissipation air duct, which can reduce the weight of the housing and further improve heat dissipation efficiency.

[0022] A fan 2 is installed at the center of the upper shell 11. A multi-air duct structure 3 is formed on both sides of the fan 2. The air generated by the fan 2 is diffused to the entire surface of the shell through the multi-air duct structure 3 and flows out to both sides, improving the heat dissipation efficiency. The multi-air duct structure 3 includes multiple baffles 31, and air ducts 32 are formed between the baffles 31. The air ducts 32 include horizontal air ducts 321 and vertical air ducts 322. The horizontal air ducts 321 are located on both sides of the fan 2 to direct the air from the fan 2 to both sides. The vertical air ducts 322 are located at the upper and lower ends of the horizontal air ducts 321 to diffuse the air from the fan 2 to the upper and lower ends of the shell.

[0023] In order for the airflow of fan 2 to enter the vertical air duct 322 well, the baffle 31 of the vertical air duct 322 is designed with an arc near the horizontal air duct 321 to guide the airflow. The left and right baffles 31 have opposite arcs, with the center of the arc facing the middle of the housing, so as to realize the structure of guiding the airflow of fan 2 from the center to both sides, which further improves the heat dissipation efficiency.

[0024] The lower shell 12 has multiple mounting holes 4. The upper shell 11 and the lower shell 12 are fixedly connected through the mounting holes 4. Specifically, screws pass through the mounting holes 4 on the lower shell 12 and the fixing holes on the inside of the upper shell 11 to fix the upper shell 11 and the lower shell 12.

[0025] The upper half of the housing is the mounting position for the bidirectional wireless image transmission circuit board. The upper half of the lower housing 12 has multiple grooves 6 to reduce the overall weight of the housing. To further improve heat dissipation, the lower half of the lower housing 12 has multiple heat dissipation ducts 5. The multi-duct structure 3 on the upper housing 11 and below the fan 2 has multiple through-holes 7. These through-holes 7 direct the airflow from the fan 2 into the heat dissipation ducts 5 of the lower housing 12, carrying away the heat from the wireless image transmission module and reducing the weight of the housing. Specifically, the heat dissipation holes 7 are located within the air ducts 32 on the left and right sides of the lower half of the housing, with multiple holes within each air duct 32.

[0026] The upper end of the housing has antenna mounting threads 8 on both sides for mounting the antenna. The lower end of the housing has multiple interface grooves 9 for accommodating multiple interfaces of the bidirectional wireless image transmission circuit board, including power interface, communication serial port, network interface, etc.
