Claim 0:
1. A battery carrier for supporting one or more electric battery modules for an electrically operable vehicle, comprising:
a support tray formed from a material blank tray that comprises a double-walled tray base configured to support the one or more electric battery modules and double-walled or single-walled sidewalls that delimit the double-walled tray base at opposing sides of the double-walled tray base; and
a heat exchanger structure with hollow channels formed in the double-walled tray base that are configured to allow a fluid to pass through to regulate a temperature of the one or more electric battery modules,
wherein each of the hollow channels comprise respective first hollow channel sections that are separated from one another and extend from one end of the double-walled tray base and respective second hollow channel sections that are separated from one another and extend from another end of the double-walled tray base,
wherein the hollow channels of the heat exchanger structure are of serpentine form or are formed as annularly longitudinally extended cells, wherein the hollow channels comprise third hollow channel sections, that are fluidically branched in parallel from the first hollow channel sections and then join together at fourth hollow channel sections of the hollow channels, and wherein the double-walled material blank is a blank that is assembled using laser welding, soldering, or roller seam welding,
wherein one wall of the double-walled material blank which faces an interior of the support tray is thicker than a wall of the double-walled material blank which faces away from the interior of the support tray,
wherein the double-walled tray base provides a flat surface for the mounting of a battery module, wherein the double-walled or single-walled sidewalls have an angled flange in each case, which serves for the fastening of a cover on the support tray,
wherein one or more first sidewalls of the double-walled or single-walled sidewalls of the support tray are configured with an angled joint plate connected in a materially bonded manner to a second sidewall of the double-walled or single-walled sidewalls of the support tray, wherein the second sidewall adjoins the one or more first sidewalls,
wherein an opening of a first hollow channel of the hollow channels is provided with a fluid inlet connector, wherein an opening of a second hollow channel of the hollow channels is provided with a fluid outlet connector.
