Resumen de: EP4550539A2
The present application provides a temperature control component, which includes a first side plate, a second side plate and a first buffer plate. A cavity is formed by the second side plate and the first side plate; the first buffer plate is disposed between the second side plate and the first side plate to divide the cavity into multiple channels, and at least part of the first buffer plate extends obliquely from the first side plate towards the second side plate. The present application also provides a battery pack, which includes the temperature control component described above. When external air flows through the channels of the temperature control component, heat dissipation treatment for batteries could be realized. During use of the battery pack, expansion forces of two adjacent batteries extrude the first side plate and the second side plate respectively. Because at least part of the first buffer plate extends obliquely, the expansion forces transmitted to the first buffer plate are reduced, thereby extending the service life of the temperature control component. Moreover, the at least part of the first buffer plate which extends obliquely is more prone to a bending deformation under the action of the expansion forces, so that the temperature control component could absorb the expansion forces of the batteries in time, thereby improving the service life of the batteries.
