Abstract: A heat dissipation apparatus is provided, and the apparatus includes an evaporator and a plurality of ribbed plates. The evaporator has a first cavity, and the first cavity is configured to accommodate a working medium for vapor-liquid two-phase conversion. The ribbed plate includes a first side plate and a second side plate, a side that is of the first side plate and that faces the second side plate has a plurality of first protruding parts, a side that is of the second side plate and that faces the first side plate has a plurality of second protruding parts, and each first protruding part is fixedly connected to one corresponding second protruding part, so that a second cavity between the first side plate and the second side plate is divided into channels that are connected to the first cavity. The apparatus is used to effectively dissipate heat for a base station.
