Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency switching power supplies, in particular to a high-frequency switching power supply device. Background Art

[0002] A high-frequency switching power supply is a power supply device that converts AC power into DC power. It is widely used in communication equipment such as communication base stations, switches, and routers. These devices require a stable and efficient DC power supply to ensure their normal operation. High-frequency switching power supplies can meet the communication equipment's requirements for high reliability, wide voltage regulation range, and high efficiency, providing a guarantee for the stable operation of communication networks.

[0003] High-frequency switching power supplies are available in box form, usually with a rectangular or square appearance. This type of box is easy to install and place on various equipment cabinets or workbenches. The internal space is relatively regular, making it convenient to layout and install the various components of the high-frequency switching power supply. For example, this type of rectangular box-type high-frequency switching power supply is often used in some industrial automation equipment and communication equipment cabinets.

[0004] Since high-frequency switching power supplies generate heat during use and are affected by the environment, the internal temperature is relatively high. Although box-type high-frequency switching power supplies generally have fans to dissipate heat internally, their heat dissipation efficiency is low, making it difficult for the box to meet the heat dissipation conditions of the high-frequency switching power supply.

[0005] In order to solve the above problems, this application proposes a high-frequency switching power supply device. Utility Model Content

The sensor can detect the gas temperature. The cold air inlet pipe can be used alone to dissipate heat for the high-frequency switching power supply. The cold air and hot air can be mixed to regulate the temperature inside the box, thereby achieving the purpose of regulating the working environment temperature of the high-frequency switching power supply.

[0017] In summary, the high-frequency switching power supply can be cooled separately to achieve the effect of heat dissipation, and the working environment temperature of the high-frequency switching power supply can be regulated by using a mixture of cold air and hot air.
