HEAT EXCHANGE COMPONENT, BOX, BATTERY, AND ELECTRICAL APPARATUS

A heat exchange component, a box, a battery, and an electrical apparatus are provided. The heat exchange component applied to the battery includes a body. The body includes a plurality of chambers penetrating through the body in a second direction, the plurality of chambers being arranged in a first direction. The plurality of chambers comprise an edge chamber located at an end of the body in the first direction, and a non-edge chamber located at a side of the edge chamber toward a center of the body. The cross-sectional area of the edge chamber perpendicular to the second direction is smaller than that of the non-edge chamber perpendicular to the second direction, so as to reduce the capacity of a heat exchange medium in the edge chamber.
