Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation devices for rectifiers, in particular to a heat dissipation device for rectifiers which is easy to install. Background Art

[0002] In the "green economy" of new energy, high-speed rail, electric vehicles, smart grids and other industries, power electronics have appeared without exception. Rectifier is a device that converts AC into DC. It can be used for power supply devices and detection of radio signals. It is one of the core modules of power electronics and is widely used in rail transportation, aerospace, new energy vehicles, wind power generation and other industries. It has two main functions: first, it converts AC into DC, supplies the load or inverter after filtering; second, it provides charging voltage to the battery. Therefore, it also acts as a charger. Especially in the fields of maglev trains and marine vessels, higher requirements are put forward for rectifiers, including good heat dissipation performance, high voltage, high reliability, strong environmental adaptability, miniaturization, etc. During the use of the rectifier, a heat dissipation device is often needed to cool the surface temperature of the rectifier.

[0003] For example, the utility model with the publication number CN212936519U discloses a heat dissipation device for a rectifier, including a heat sink fixed on one side of the rectifier, and a heat dissipation fan installed on the heat sink, the heat dissipation fan is connected to a relay through a heat dissipation fan wire, the relay is connected to a PLC controller through a data line, the PLC controller is connected to a thermocouple, a thermocouple clamping device is installed on a side of the heat sink perpendicular to the heat dissipation fan, and the temperature measuring end of the thermocouple is placed in the thermocouple clamping device. The device dissipates heat for the rectifier through the heat sink and the heat dissipation fan, and uses the PLC controller to control the relay so that the heat dissipation fan is turned on or off according to the design of the program, which can also save electricity.

[0004] Although the heat sink for the rectifier has the advantage of saving electricity, it is not easy to quickly install the heat sink to the surface of the rectifier during the installation process, which makes the installation method more complicated and difficult to perform cold air treatment on the surface of the rectifier, resulting in a relatively simple heat dissipation effect of the rectifier, affecting the subsequent use of the rectifier. Therefore, in view of the above problems, a heat sink for the rectifier that is easy to install is proposed. Utility Model Content
