When it comes to heat dissipation of
solar street light, many people will say that poor heat dissipation will always occur in summer, which will affect the normal operation and service life of solar street light. Then let's think about it. Generally, in the current solar street light manufacturers, when designing, the LED terminals and the heat sink are combined together to transfer heat to the heat sink. There are two problems here, one is the transmission of heat. The problem of thermal performance, if the heat transfer performance is not good, no matter how good the heat sink is, it is useless. The quality of the heat transfer performance is determined by the contact surface between the LED terminal and the heat sink. If the contact is absolutely flat, silicone grease is completely unnecessary. Only because it is not absolutely flat, silicone grease is used. In uneven places, the heat is transferred to the heat sink by silicone grease, which is definitely not the silica gel mentioned on the Internet. Well, there is no object with good direct heat transfer effect. Therefore, silicone grease, as long as it can transfer heat without contact at least, can not transfer heat effectively. The second problem is that the LED terminal transfers heat to the heat sink. In theory, the temperature of the heat sink, It is the temperature of the LED terminal. If the heat dissipation temperature goes down, the temperature of the LED terminal can also go down. The heat sink is determined by (the heat dissipation material. There is also the air flow to help heat dissipation, which is a requirement for the design of the heat sink.) The larger the heat sink, the better the effect, and vice versa. How to effectively make the heat sink larger, many people here will say, get a large heat sink. For the sake of cost and aesthetics, the shape has become a bottleneck (the imported cooling technology mentioned here is a kind of teaching for people who do not understand, mainstream cooling, air cooling, water cooling) Therefore, we will think How to increase the volume of the heat sink, as shown in the figure, if the heat of 1 is transferred to 2, then transferred from 3 to 4, then transferred to 5, and then transferred to the ground by 5, this is a big cooling system, In the same way, before making this system, I think about the aspects mentioned above. I think everyone can understand it. No royalties are required. Give it a like!
