A battery cooling device may include a refrigeration circuit configured to communicate a refrigerant in a flow direction. The refrigeration circuit may include a plurality of refrigerant paths configured to be flowed through in parallel by the refrigerant along the flow direction. The plurality of refrigerant paths may respectively include at least one of a cooling element and a cooling element section. The at least one of the cooling element and the cooling element section may be fluidically incorporated into the respective refrigerant paths and be thermally coupled in a heat-transmitting manner to at least one battery. A plurality of valve devices may be arranged in the respective refrigerant paths and be configured to control a throughflow of the refrigerant.

Battery cooling device and associated operating method

A collector for accommodating at least two flat tubes of a heat exchanger, which are disposed so as to be mutually parallel and each of which has a broad side and a narrow side, may include a first element and a second element. The first element may be configured as a metal strip, and the second element may be configured as one of an extruded section or a formed sheet-metal part. At least two punched through openings each configured as a passage for receiving one of the flat tubes may be provided in at least one of the first element and the second element. The at least two punched through openings may further be oriented parallel to a longitudinal axis of the collector by way of the broad side of the flat tubes.
