[0008] The purpose of the present revelation is to create another efficient battery carrier.
[0009] This problem is solved by the features of the independent claims. Advantageous embodiments are the subject of the dependent claims, the description, and the accompanying figures.
[0010] The present disclosure is based on the finding that the above problem can be solved by a battery carrier which, as a functional component, has an integrated functionality that goes beyond simply holding battery modules. Such functionality is the temperature control of the electrical battery modules, in particular the cooling and / or heating of the electrical battery modules.
[0011] This eliminates the need for separate functional components, thereby reducing manufacturing costs.
[0012] According to a first aspect, the disclosure relates to a battery carrier for receiving at least one electric battery module in a vehicle, comprising a plate-shaped hollow channel body having an end face and a receiving base for receiving the electric battery module, wherein a fluid-permeable heat exchanger for temperature control of the electric battery module is formed within the plate-shaped hollow channel body, wherein the heat exchanger has a first fluid hollow channel and a second fluid hollow channel, wherein the first fluid hollow channel opens at the end face into a first fluid outlet opening, wherein the second fluid hollow channel opens at the end face into a second fluid outlet opening, and a fluid collector for receiving fluid exiting from the first fluid hollow channel and the second fluid hollow channel.wherein the fluid collector has a fluid receiving section for receiving fluid from the first fluid outlet opening and from the second fluid outlet opening, and a fluid discharge channel for discharging fluid, wherein the fluid discharge channel is fluidically connected to the fluid receiving section, and wherein the fluid receiving section is force-fitted to the end face of the plate-shaped hollow channel body.

[0014] The fluid channels are thermally coupled to the mounting base. This ensures that at least one electrical battery module mounted on the base is in thermal contact with the fluid flowing through the channels. This fluid effectively controls the temperature of the electrical battery modules, particularly effective heating and / or cooling.
[0015] After heat exchange with the electrical battery modules, the fluid can efficiently flow from the fluid channels through the respective fluid outlet opening into the fluid intake section of the fluid collector. The fluid collected in the fluid intake section can then be discharged from the fluid collector through the fluid discharge channel. This ensures a continuous removal of fluid from the fluid channels.
[0016] The heat exchanger can be part of a refrigeration or heating circuit in the vehicle. The fluid collector can be made of plastic or metal, such as aluminum.
[0017] Furthermore, the heat exchanger is not limited to two fluid channels.

[0023] This achieves the advantage that the fastening screws engaging in the threaded receptacles enable an effective, force-fit fastening of the fluid intake section to the end face of the plate-shaped hollow channel body. Because the threaded receptacles are formed, in particular, laterally to the fluid hollow channels in the end face and, in particular, run parallel to the fluid hollow channels, effective fastening can be ensured without restricting the geometry of the fluid hollow channels with respect to the threaded receptacles. The fastening screws can be designed, in particular, as M5 screws.

[0054] In one embodiment, the fluid hollow channels are arranged below the receiving base and thermally coupled to the receiving base.
[0055] This achieves the advantage that the fluid channels located below the mounting base do not impair the design of the mounting base for the electrical battery module. The thermal coupling between the fluid channels and the mounting base allows for effective heat exchange between them.
