PC power supply thermal cooling
The cooling fan on the PC power supply is believed to be used by everyone. In the early years, the fan in the power supply has neither intelligent stop technology nor temperature control and speed regulation technology. In order to ensure the cooling effect, generally, the products with high speed are selected, and the noise is quite obvious when running.
In the mainstream power supply, temperature control and speed regulation has been a necessary item. Further, intelligent shutdown has been made. In addition to the intelligent shutdown of the fan, there are power products that directly remove the fan and reduce the working temperature of the power supply in the way of passive heat dissipation.
In fact, most power supplies only show a small amount of heat on the shell, and the temperature inside the power supply is not easy to be monitored by software, so it naturally lacks an intuitive feeling. In fact, the power supply does not necessarily run stably without the cooling fan, and its internal heating capacity may be higher than expected.
Heatting source of the PC power supply:
PC power supply is composed of various components, including resistance, capacitance, inductance, rectifier bridge, switch tube, transformer and so on. The power supply will generate heat in the working process, and these heat will be included in the loss of power supply energy, which is also the performance index of PC power supply such as conversion efficiency. The higher the conversion efficiency, the lower the loss, and the heating of power supply will be reduced.
How to cooling down the power supply:
Although the loss of power supply is not only shown in the form of heat, the heat of power supply does come from the loss of power supply. Therefore, reducing the loss of power supply can reduce the heating of power supply to a certain extent. Reducing the loss of power supply means improving the conversion efficiency of power supply.
The higher the conversion efficiency, the higher the requirements for power structure, workmanship and materials, and the higher the overall cost. It is easier to see the effect by directly improving the heat dissipation efficiency of the power supply. It is more common to use better thermal solutions, including heat sink ,liquid cooling system and cooling fan.
In fact, the heating capacity of the power supply is not low, but most of the power supplies can not monitor the temperature through software like CPU and GPU. Most of the components inside the power supply can work normally under high temperature. The thermal solutions configured by the manufacturer for the power supply has also been tested for a long time.
