Abrégé
(EN)
The invention discloses an electric control box and relates to the electric control equipment field. The electric control box is used to enlarge an internal usage space of the electric control box and simultaneously optimize cooling performance. The electric control box comprises a box body. A plurality of external surfaces of the box body are provided with cooling fins. An internal portion of the box body is divided into at least two layers of spaces by a separation plate. The separation plate is made of a heat conduction material. The separation plate and the box body are connected in a heat conduction mode. In the above technical scheme, an internal space of the electric control box is divided into multiple layers; a bottom layer can be directly cooled through the electric control box; and a component in each layer of space can rapidly transmit heat to the cooling fins of the external surfaces of the box body through the separation plate. Therefore, based on conditions that an internal space utilization rate of the electric control box and versatility are increased, a fanless structure of the electric control box is realized so that the electric control box is basically silent.
