Air cooling includes two types: natural cooling and forced air cooling.

The mechanism of natural cooling is that during operation, the temperature of the component will increase, creating a temperature difference between the component and the environment. Therefore, spontaneous heat exchange between the component and the environment begins. This process can be carried out spontaneously without the need for additional energy and power, without the need for designing cooling auxiliary equipment. It directly relies on air cooling with lower external temperatures, resulting in low energy consumption, high reliability, and low noise. But this solution is limited in high-power cooling scenarios.

Cold plate cooling: Cold plate cooling is a kind of Indirect liquid cooling .It refers to the indirect exchange of heat between heating components and coolant through the use of a "cold plate" instead of direct contact for heat transfer. Indirect liquid cooling has many obvious advantages, such as simple equipment, compact structure, convenient maintenance, no pollution to the IGBT module of the inverter, and minimal noise generated during operation.

Heat pipe is an efficient heat exchange component, which works by filling the enclosed shell with a working medium. During the phase change process, the medium undergoes heat exchange through heat absorption and release. Heat pipes are made of high thermal conductivity materials, hence they are known as superconducting thermal bodies. Compared to metal conductors with good thermal conductivity, the thermal conductivity of heat pipes is nearly a hundred times higher. The advantages of heat pipes include good thermal conductivity, excellent isothermal performance, and environmental adaptability. However, it is generally used in situations that require long-distance heat transfer or uniform temperature, and it is difficult to meet the heat dissipation requirements of high-power wind power converters.
