General radiator 003 - Power radiator

Radiators can be generally divided into three types based on their structure and working principle:
1. Power supply radiators, also known as active radiators. As the name suggests, power supply radiators are used for power supplies, typically consisting of heat sinks and fans, such as CPU coolers in computers. They can be further divided into four types based on the structure, material, and heat conduction method of the heat sink.
(1) Pure aluminum alloy (or pure copper) heat sink + fan, for example, widely used aluminum alloy (or pure copper) power supply coolers for computer CPUs;
(2) Aluminum alloy fan fins + copper pipes (containing heated media, usually liquid, and sometimes aluminum pipes) or stainless steel pipes (for highly corrosive heated media, mainly used in the chemical industry) + fan, for example, CPU water cooling fans, air conditioning radiators, car radiators, etc., where good heating effects are essential;
(3) Aluminum alloy heat sink + copper conductive block + fan, also known as aluminum-plug copper radiators, which are least applied to CPU coolers in computers;
(4) Aluminum alloy fan fins + pure copper heat pipes + pure copper (or aluminum alloy) conductive block + fan, also known as heat pipe radiators, which are currently a popular fan method for CPU coolers in computers;
2. Electronic radiators are typically heat sinks for high-power electronic components without additional power supply; they naturally generate heat and are mostly made of aluminum alloy profiles, cut to necessary sizes based on component size, such as heat sinks for high-power power tubes or transistors. Of course, in similar situations, ultra-high-power electronic components may also have fans attached; for example, the power tube of a switch power supply must be equipped with a fan.
3. Heat exchangers usually involve two media that do not have a temperature difference and flow separately within pipes (or within fan blocks) and outside the pipes (or in another closely adjacent fan block or convective body) to exchange heat with each other. For example, CPU water cooling heads, radiator panels, gas water heaters; heat exchangers typically do not use power supplies and fans themselves but rely on natural air or liquid convection or additional air pumps or liquid pumps to force media flow.
