The invention provides a power distribution cabinet with a directional heat dissipation function, which comprises a cabinet body, a cabinet door, longitudinal guide rails, a transverse guide rail, a rack and the like. The cabinet body is of a cuboid frame structure; five surfaces of the cabinet body are formed by
welding steel plates with a specification of 3mm; the cabinet door is rotationally connected with the cabinet body; two longitudinal guide rails which are vertically mounted are arranged inside the cabinet door; and the longitudinal guide rails are of a cylindrical structure, and are mounted inside the cabinet door by guide rail mounting bases. According to the power distribution cabinet provided by the invention, an
infrared temperature sensor is driven by movable sliding blocks to measure temperatures of
electrical devices in the cabinet body, so that positions of the
electrical devices with high temperatures can be accurately monitored; and then a fan is used for carrying out focused heat dissipation on the
electrical devices, so that a heat dissipation effect is improved.
