Today, with advanced technology, how do smart high-tech products dissipate heat?
Drone With the rapid development of science and technology, the market has higher and higher requirements for the performance of drones, such as image transmission speed and clarity. However, the size of drones should be as small as possible, which makes it more difficult to design heat dissipation materials for the overall equipment. Come bigger.
The two cores of the UAV are the motor and the ESC (that is, the electronic governor). The flight of UAVs is driven by propellers or turbofans.
The power that drives them to rotate comes from motors, but the speed and power of the motors are controlled by ESCs. Therefore, the ESCs are indispensable for the smooth flight of UAVs. of. If the performance of the motor ESC is overheated and the performance is degraded, 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 a top priority.
The heat dissipation structure of the UAV includes a connecting block, a mounting plate, a heat sink, a heat pipe, and a heat exhaust port; there are heat pipes installed on both sides of the top of the heat sink, heat exhaust ports are installed inside the heat sink, and connections are installed on both sides of the heat sink Mounting plates are installed on both sides of the connecting block. The heat sink 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 bottom plate are connected with the connecting block. The layout of drone motors and ESCs is often relatively compact. If thermally conductive silicone sheets are used, it is inconvenient for the operator to pick and place and install due to the small size. Thermally conductive gels are better than thermally conductive silicone sheets in actual operation.
The thermal gel realizes the automatic dispensing operation of the equipment, which is more compatible with the operation of today's high-tech production lines.
The thermal conductive gel is mainly used for heat dissipation between the image transmission main board and the heat sink; the thermal conductive gel, the heat pipe and the heat exhaust port are used together, and the heat pipe can effectively absorb the heat inside the drone during use. The hot port quickly dissipates the heat on the radiating pipe, which solves the phenomenon of poor heat dissipation.
Thermally conductive gels are not as well-known as thermally conductive silicone sheets in heat dissipation applications in drones and other electronic products, but thermally conductive gels play a very important role in the iteration of drone technology.
Smart projector : In recent years, projectors have been widely used in offices, entertainment venues, homes, schools and other places. In order to better optimize user experience, projector products continue to evolve. However, while improving functions, they must effectively exhaust heat and maintain a stable temperature. , To ensure work efficiency.
According to the imaging principle of the projector, when the projector projects the input signal, it needs extremely high brightness. In order to ensure such a high brightness output, the projector must be realized by using a high-power light source. After a long period of work, a high amount of heat will inevitably be generated inside the machine. In addition to the heat generated by the projector's light source, the projector's power supply also generates a lot of heat during operation.
The heat generated by the projector bulb, imaging system, power supply, etc. is concentrated in a small space inside the machine. The high temperature generated not only affects the normal use of the projector, but also greatly shortens the service life of internal components.
The heat dissipation structure of the projector includes a heat pipe, a plurality of fins arranged on the heat pipe, and a fan arranged on one side of the plurality of fins. One end of the heat pipe is fixedly connected to the light source side of the projector body, and the other end is away from the projector body. A plurality of fins are fixed on the end of the heat pipe away from the projector body. The fan is electrically connected to the projector body. Drive the air flow to reduce the temperature of the fins. The heat generated by the main body of the projector can be transferred to the fins through the heat pipe, and then the fan drives the flow of air to reduce the temperature of the fins. In this way, the heat dissipation of the projector is accelerated, and at the same time, the problem of high-temperature air staying near the main body of the projector and affecting the normal operation of the projector is avoided. If the projector is used in an area with high temperature all year round, it is not enough to rely on the fan to dissipate heat. Therefore, many companies reform the fans installed inside the projector, including the heat dissipation method and heat dissipation materials, and fundamentally solve the problem that the projector cannot be continuous. The problem of work.
The thermal conductive silicone gasket is soft, thermally conductive and insulating, especially its compressibility is good, the thickness can be adapted to the space range of different smart projectors, and the controllability is good. The thermal conductive silicone sheet is well filled between the projector’s heat pipe fins and the cooling fan to achieve a seamless connection between the heat source and the cooling fan. The heat is transferred out to maintain a stable temperature of the projector and ensure its working efficiency.
