Abstract: Embodiments of the present invention relate to a heat dissipation apparatus and relates to the field of heat dissipation technologies, so as to solve a problem that heat dissipation efficiency of heat dissipation fins of an existing heat dissipation apparatus is low. In embodiments of the present invention, the heat dissipation apparatus includes a base plate, where multiple main fins are disposed on the base plate, and multiple auxiliary fins are disposed on the main fins; a gap exists between the auxiliary fins and the base plate; and a blocking structure is disposed and fastened on the base plate and/or the main fins, and the blocking structure can make cooling airflow first flow along the auxiliary fins and then flow along gaps between adjacent main fins and flow out. The present invention is mainly used in the field of communication accessories.

Abstract: A heat dissipation apparatus including multiple heat exchange sheets. A first path and a second path are formed between the multiple heat exchange sheets, and the first path includes a first countercurrent channel, a guide channel, and a first-outlet cross-flow channel; the second path includes a second countercurrent channel and a second-inlet cross-flow channel. One part of a first fluid that enters the first path enters the first countercurrent channel and mainly performs countercurrent heat exchange with a second fluid that is in the second countercurrent channel, and the other part passes the guide channel and rapidly performs cross-flow heat exchange.

Abstract: Embodiments of the present invention provide a storage battery cabinet and storage battery system. One or more storage batteries are placed in a bottom space in the storage battery cabinet, through holes are separately opened in two opposite cabinet walls at a top of the storage battery cabinet, and a hydrogen evolution isolation component with openings is disposed in a space above the one or more storage batteries in the storage battery cabinet. The hydrogen evolution isolation component divides an internal space of the storage battery cabinet into an upper area and a lower area, and the hydrogen evolution isolation component is capable of allowing hydrogen generated by the one or more storage batteries to pass and discharge out of the storage battery cabinet from the through holes, and reducing air convection between the upper area and the lower area.
