The present application provides a heat-exchanging component, a method for manufacturing the heat-exchanging component, a system of manufacturing the heat-exchanging component, a battery and an electricity-consuming apparatus. The heat-exchanging component provided by the embodiments of the present application includes a first plate body and two second plate bodies. The first plate body includes a first main body, a first convex portion and a second convex portion, and the first convex portion and the second convex portion protrude from a surface of the first main body away from the accommodating space; in a thickness direction of the first main body, a size of the first convex portion protruding from the first main body is smaller than a size of the second convex portion protruding from the first main body; the first flow passage is formed inside the first convex portion.

A battery module includes: a battery cell stack in which a plurality of battery cells are stacked; a module frame for accommodating the battery cell stack; and a heat sink formed on the lower side of the module frame to cool the plurality of battery cells. The heat sink includes a lower plate and a flow path part which defines a flow path for a refrigerant. The flow path part includes: a first path set that collects first flow paths formed in a direction perpendicular to the stacking direction of the battery cell stack; and a second path set that collects second paths formed in a direction parallel to the stacking direction of the battery cell stack, whereby a total length of the second path set is longer than a total length of the first path set.

A battery module according to an embodiment of the present disclosure includes: at least one battery cell; a bus bar assembly connected to an electrode lead of the at least one battery cell and positioned on both side surfaces of the at least one battery cell; and a heatsink assembly positioned in direct contact with both of the at least one battery cell and the bus bar assembly while surrounding both of the at least one battery cell and the bus bar assembly.

A battery system includes a plurality of battery modules each formed from a plurality of battery cells. A shared cooling structure is thermally coupled to each of the battery modules. The shared cooling structure is configured to conduct heat relative to the battery modules. A thermal interface is disposed between the battery cells of each battery module and the shared cooling structure. Each thermal interface is configured to transition from a first thermal conductivity state to a second thermal conductivity state when heat generated by the respective battery cells exceeds a threshold level. The second thermal conductivity state is lower than the first thermal conductivity state such that after one of the thermal interfaces has transitioned from the first thermal conductivity state to the second thermal conductivity state, heat transfer from the respective battery cells to the shared cooling structure is reduced.

A battery module includes a module case, a battery cell assembly that is received in the module case, a heat sink mounted below the module case, and a heat pipe member mounted inside an upper side of the module case. The battery cell assembly includes battery cells, each of which has an electrode lead drawn to one or two sides thereof. The battery cells are stacked along a horizontal direction of the module case such that an edge of each of the battery cells not having an electrode lead is oriented downwardly facing the heat sink. The heat pipe member includes an evaporator and a condenser, the evaporator being formed on a side of the electrode leads of the battery cells, and the condenser being in contact with an inner surface of the module case.

An apparatus includes multiple thermal actuator switches configured to control a transfer of thermal energy. The thermal actuator switches are arranged in a stacked configuration. Each switch includes first and second plates and a piston movable between the plates. Each switch also includes a phase change material configured to (i) expand to move a surface of the piston into a first position and (ii) contract to allow the surface of the piston to move into a second position. The surface of the piston thermally contacts the first plate and increases thermal energy transfer between the plates when in one of the first and second positions. The surface of the piston is spaced apart from the first plate and decreases thermal energy transfer between the plates when in another of the first and second positions. Different ones of the switches include different phase change materials that expand or contract at different temperatures.

A multi-stage cascaded thermoelectrical cooler (TEC) package is used in conjunction with an air cooling system to control temperature of battery cells in a battery module such that the temperature differences stay within a predetermined range. Battery cells in the battery module are divided into one or more regular sections and one or more TEC enhancing sections. A regular section and a TEC enhancing section can use different types of battery cell holders to assemble the battery cells. TECs in the TEC package are integrated into each enhancing section, where each stage of the TEC package is attached to one or more battery cells in a different region of the enhancing section. A higher stage, which is more powerful in enhancing heat transfer and extracting heat from battery cells, is attached to one or more battery cells in a section closer to the air outlet. The TEC package is powered by a discharging convertor circuit of the battery module.
