In contemporary computer products, the essence of the heat dissipation system is basically the same. The heat dissipation system is essentially composed of two parts: heat conduction and air exchange. For ease of understanding, the CPU/GPU can be imagined as a "factory" and the heat generated by them as a "product", while the heat exchanger can be seen as a back-end logistics and sales company, with the heat conduction part The heat storage part serves as the "logistics" and "warehouse", the fins are the "salesperson", and the fans are the "marketing" Based on the above concepts, let's summarize the working method of heat dissipation: the factory produces products, the products are transported by logistics to the sales end, the salesperson sells the products to customers, and marketing attracts more customers for the salesperson. Isn't that clear? Chapter 1. Air Cooling Air cooling is currently the most basic heat dissipation method. Whether it is a desktop computer or a laptop, its structure is basically the same: copper tubes, fins, fans, and some high-end heat dissipation modules have uniform heat plates. However, the uniform heat plate is essentially a flattened shaped heat pipe, which can be attributed to the heat pipe; According to the previous understanding, the uniform heat plate and copper tube are equivalent to "logistics", the fins are "salespeople", and the fans are "marketing". They work together to sell (discharge) the product (heat). Typical air-cooled radiator, consisting of a uniform heat plate, copper tube, fins, and fan
