Heatsink for Switch Mode Power Supply

Switch Mode Power Supply (SMPS) is also called switching power supply or switching converter. It is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage of a certain level into the voltage or current required by the user through different forms of architecture. Switching power supply uses power electronic switching devices such as diodes, IGBTs and MOSFETs, transformers (such as transistors, field effect transistors, thyristors, etc.) to control circuits to make electronic switching devices "on" and "off" continuously, so that electronic switching devices can pulse-modulate the input voltage, thereby realizing DC/AC and DC/DC voltage conversion, as well as adjustable output voltage and automatic voltage regulation.

Switching power supplies can be divided into two categories: AC/DC and DC/DC. DC/DC converters have now been modularized, and the design technology and production process have been mature and standardized at home and abroad, and have been recognized by users. However, the modularization of AC/DC, due to its own characteristics, encounters more complex technical and process manufacturing problems in the process of modularization. In addition, the development and application of switching power supplies are of great significance in saving energy, saving resources and protecting the environment.

Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD monitors, LED lamps, communication equipment, audio-visual products, security monitoring, computer cases, digital products and instruments.

When the switching power supply is working, a lot of heat will be generated. If the heat cannot be discharged in time and kept at a reasonable level, it will affect the normal operation of the switching power supply, and in severe cases, it will damage the switching power supply. Hongwei designs and manufactures various metal fin heat sinks to meet the thermal management and temperature protection requirements of heating components (diodes, IGBTs, MOSFETs, transformers, etc.) in switching power supplies.
