[0002] A bridge rectifier is a circuit that is usually used to convert alternating current into direct current. It is a rectifier device consisting of two or four diodes that are arranged in a bridge-type structure, hence the name "bridge". In a bridge rectifier, the AC input is connected to the two diagonals of the bridge, while the DC output is connected to the other two diagonals. When AC is input, the bridge rectifier converts it into DC of the corresponding polarity based on the polarity of the input voltage. The bridge rectifier has a simple structure, low cost, and high efficiency, so it is widely used in various electronic devices.

[0003] However, when the existing rectifier bridge stack is in use, due to the lack of effective heat dissipation measures inside, the diodes will heat up seriously after working for a long time, resulting in serious aging of the diodes, which will damage the rectifier bridge stack and make it unable to work normally, thereby reducing the service life of the rectifier bridge stack. Secondly, it is also cumbersome to install and disassemble the rectifier bridge stack. For this reason, we propose a rectifier bridge stack that is conducive to heat dissipation to solve the above problems. Utility Model Content
