With the rapid development of science and technology, the market has higher and higher requirements for the performance of UAVs, such as image transmission speed and clarity. come bigger.
The two cores of drones are the motor and the ESC (that is, the electronic governor). The flight of drones is driven by propellers or turbofans, and the power to drive them to rotate comes from the motor, but the speed and power of the motor are controlled by the ESC, so the smooth flight of the drone is due to the ESC. of. If the motor ESC overheats and causes performance degradation, the ESC cannot control the motor speed well, and the flight controller cannot withstand such a large current. Therefore, solving the problem of UAV heat dissipation is the top priority.
The heat dissipation structure of the drone includes a connection block, a mounting plate, a heat dissipation plate, a heat dissipation pipe, and a heat exhaust port; the heat dissipation pipe is installed on both sides of the top of the heat dissipation plate, the heat dissipation port is installed inside the heat dissipation plate, and the connection is installed on both sides of the heat dissipation plate. There are mounting plates installed on both sides of the connection block. The heat dissipation plate includes a heat dissipation base plate, a heat sink, an air inlet and an air outlet. There are heat sinks on both sides of the heat dissipation base plate. The side is connected with an air outlet, and the two sides of the heat dissipation base plate are connected with the connecting block.
The layout of UAV motors and ESCs is often relatively compact. If a thermally conductive silicone sheet is used, it is inconvenient for the operator to pick and place it due to the problem of small size, and the thermally conductive gel is better than the thermally conductive silicone sheet in actual operation. . The thermal conductive gel realizes the automatic dispensing operation of the equipment, which is more suitable for the operation of today’s high-tech production lines.
The thermal conductive gel is mainly used for heat dissipation between the main board and the heat dissipation plate of the image transmission; the thermal conductive gel is used in conjunction with the heat dissipation pipe and the heat exhaust port. When in use, the heat dissipation pipe can effectively absorb the heat inside the drone. The hot port quickly dissipates the heat on the heat pipe, which solves the phenomenon of poor heat dissipation.
Thermally conductive gels are not as well known as thermally conductive silicone sheets in the heat dissipation applications of drones and other electronic products, but thermally conductive gels play a very important role in the iteration of drone technology.
Thermally conductive gel is generally packaged with a syringe. This material itself does not contain solvent, and has the characteristics of high thermal conductivity, low compression force, high compression ratio, and good temperature resistance. It can be used automatically, and has good affinity and weather resistance of silicone materials. It has the advantages of high and low temperature resistance, and has strong plasticity, which can meet the filling of various uneven interfaces and meet the heat transfer requirements of various applications.
The CoolThermo thermal conductive gel series is made of silicone resin as the base material, added with thermal conductive fillers and other materials in a certain proportion, and processed into mud through a special process. Thermally conductive gel has high and low temperature resistance, weather resistance, and aging resistance, making it ideal for compact component layouts like drones.
