    Abstract: 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.

    Abstract: A temperature control apparatus and a temperature control system include at least one liquid storage device for storing liquid, at least two liquid supply devices, and a controller. Each liquid supply device is connected to the at least one liquid storage device through a first multiport valve to obtain liquid and is connected to a temperature regulating device through a second multiport valve. The controller is configured to control the first multiport valve and the second multiport valve that are connected to the controller to be conducted or not to be conducted. When the first multiport valve and the second multiport valve are conducted, each liquid supply device outputs the obtained liquid to the temperature regulating device. The temperature regulating device regulates a temperature of the liquid injected by each liquid storage device, and then supplies the liquid to at least one battery system.

    CPC classification number: H05K7/20145

    Abstract: A heat dissipation apparatus includes at least two heating components, at least two fans, and at least two isolation components. Heat dissipation channels are disposed inside the at least two heating components, and a fan is provided in each heat dissipation channel. An isolation component is coupled to an air inlet and/or an air outlet of the heat dissipation channel. The isolation component may isolate an air inlet or air outlet of each heating component from an air inlet or air outlet of another heating component, so as to avoid forming a loop between a heat dissipation channel in which a working fan is located and a heat dissipation channel in which a non-working fan is located.
