A cell fixing apparatus includes a first shell element, a second shell element, and a plurality of pressure-adding beams. The first shell element and the second shell element are relatively fixedly connected, the first shell element and the second shell element are disposed at intervals in a first direction, so that an accommodating cavity is provided between the first shell element and the second shell element, and the accommodating cavity is configured to accommodate the cell. The plurality of pressure-adding beams may be disposed on a surface of the first shell element that is away from the second shell element. The plurality of pressure-adding beams may include a first-type beam and a second-type beam. A size of the first-type beam in the first direction is greater than that of the second-type beam. The pressure-adding beams are used to limit deformation of the cell in the accommodating cavity.

Cell fixing apparatus and battery module

Embodiments of this application provide a battery module, to improve consistency of cooling effects of battery cells, so that a battery cell group has a better states of health (SOH). The battery module includes: a heat dissipation mechanical part, which includes a first heat dissipation region and a second heat dissipation region. When an average distance between a heat dissipation pipe in the first heat dissipation region and a cooling medium outflow region is longer than an average distance between a heat dissipation pipe in the second heat dissipation region and the cooling medium outflow region, density of heat dissipation pipes in the first heat dissipation region is greater than density of heat dissipation pipes in the second heat dissipation region.
