Power adapter is a small portable electronic equipment and electronic electrical Power supply conversion equipment, generally composed of shell, transformer, inductor, capacitor, control IC, PCB board and other components, its working principle from AC input to DC output; It can be divided into wall type and desktop type by connection mode. Widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.
Due to the use of a large number of high power semiconductor devices in the power adapter, such as rectifier bridge stack, large current rectifier tube, high power transistor or field effect tube and other devices, will generate a large amount of heat in the work; Once the temperature of the power supply exceeds 75℃, if the heat cannot be discharged in time and kept at a reasonable level, the normal operation of the power adapter will be affected, and the power adapter will be damaged in serious cases. In general, power adapter manufacturers will use some thermal insulation materials to help the power dissipation in the design and production, so what are the commonly used thermal insulation materials for the 12v 24v ac adapter cooling scheme?
1.Thermal conductivity potting glue
Thermal conductive glue potting is divided into sub-branch potting and overall potting, power adapter internal uneven and irregular, the need is a kind of thermal conductive material can be completely wrapped transformer, and can not be moved at will. Local potting will generally be concentrated in the heat, and can not be replaced by other thermal conductive materials. Overall potting is because part of the power supply has to work outdoors for a long time. In addition to solving the problem of heat dissipation, it should also take into account the waterproof and sealing of the power supply, so the outdoor power supply is basically using overall potting heat dissipation.
2.One component thermal conductive silica gel
One component silica gel is usually used in the local heat conduction of power supply components, and it can play the role of fixed components at the same time. It has good adhesion and sealing for metal and non-metal.
3.Thermal conductive silica gasket
Thermal gaskets for the power supply industry, the proportion of its application is usually small, but sometimes it is necessary, usually power adapter on the thermal gasket application is mainly focused on PCB board, a special application and demand will certainly have a special supply to meet it. The thermal gasket is applied to THE PCB board, with high thermal conductivity efficiency, electrical insulation, shockproof and puncture proof and other functions, can effectively solve the safety problems for the client.
Of course, the power adapter in addition to the above mentioned thermal sealing glue, thermal silicone, thermal gasket, and thermal double-sided adhesive, thermal grease, thermal phase change materials and other thermal materials for optional, mainly see what products are used in, if you want to know more about the thermal material application, welcome to inquire.
