Abstract
The utility model discloses a heat dissipation plate and a rectifier bridge thereof, and the heat dissipation plate comprises installation plates which are fixedly attached to the surfaces of the two sides of the rectifier bridge, and the installation plates are arranged in an arc shape. A plurality of annular plates are uniformly distributed on the mounting plate; a plurality of inner heat dissipation strips are arranged on the inner wall of the annular plate in an annular array mode, the inner ends of the inner heat dissipation strips abut against the outer wall of the main rectifier diode, and a plurality of outer heat dissipation strips are evenly distributed on the outer wall of the annular plate. According to the utility model, the inner heat dissipation strips are tightly attached to the outer wall of the main rectifier diode, so that heat generated by the main rectifier diode can be quickly absorbed and efficiently transmitted to the outer heat dissipation strips through the annular plate. The outer heat dissipation strips are designed in a wave shape, so that the heat dissipation area is increased, the air flowing path is optimized, and heat can be transmitted to the external environment of the rectifier bridge more quickly.
