It is the object of the present disclosure to provide another efficient battery carrier.

This object is solved by the features of the independent claims. Advantageous embodiments are the subject matter of the dependent claims, the description and the accompanying figures.

The present disclosure is based on the finding that the above object can be achieved by a battery carrier which, as a functional component, has an integrated functionality that goes beyond the mounting of battery modules. One such functionality is the temperature control of the electrical battery modules, in particular the cooling and/or heating of the electrical battery modules.

In this way, the use of separate functional components can be dispensed with, as a result of which the manufacturing costs can be reduced.

According to a first aspect, the disclosure relates to a battery carrier for accommodating at least one electric battery module in a vehicle, with a plate-shaped hollow channel body which has an end face, an upper plate side for accommodating the electric battery module and a lower plate side facing away from the upper plate side, with inside of the plate-shaped hollow channel body, a heat exchanger through which a fluid can pass is formed for temperature control of the electric battery module, the heat exchanger having a first hollow fluid channel and a second hollow fluid channel, the first hollow fluid channel opening into a first fluid outlet opening on the front side, the second hollow fluid channel on the front side in a second fluid outlet port opens; 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, the fluid discharge channel having the Fluid receiving portion is fluidly connected, and wherein the fluid receiving portion is positively secured to at least one of the plate sides.

This achieves the advantage that the form-fitting fastening of the fluid receiving section on the end face of the plate-shaped hollow channel body enables the fluid collector to be fastened to the plate-shaped hollow channel body in a manner that is easy to assemble and fluid-tight, in order to provide the fluidic connection between the respective hollow fluid channels and the fluid collector.

The fluid hollow channels are thermally coupled to the plate-shaped hollow channel body, in particular via the upper plate side of the plate-shaped hollow channel body. As a result, the at least one electrical battery module arranged on the upper side of the plate is in thermal contact with fluid that is conducted through the fluid hollow channels. The fluid can thus ensure effective temperature control of the electrical battery modules, in particular effective heating and/or cooling.

After the heat exchange with the electric battery modules, the fluid can flow efficiently from the fluid hollow channels through the respective fluid outlet opening into the fluid receiving section of the fluid collector. The fluid collected in the fluid receiving section can then are discharged from the fluid collector through the fluid discharge channel. A continuous discharge of fluid from the hollow fluid channels can thus be ensured.

The heat exchanger can be part of a refrigeration circuit or a heat circuit in the motor vehicle. The fluid collector may include a metal such as aluminum.

In one embodiment, the fluid receiving section covers the end face of the plate-shaped hollow channel body or extends along the end face.

This achieves the advantage that effective fluidic connections are ensured between the fluid receiving section of the fluid collector and the fluid outlet openings of the respective hollow fluid channels.

According to the invention, fastening openings are formed in at least one of the plate sides, with the fluid receiving section having fastening tabs or fastening rivets which engage in the fastening openings in order to fasten the fluid receiving section in a form-fitting manner.

This achieves the advantage that the fluid collector can be positively fastened to the plate-shaped hollow channel body in a particularly effective manner via the fluid receiving section. The positive connection between the fluid collector and the plate-shaped hollow channel body is realized by interlocking structures, by means of fastening rivets and/or snap-in hooks.

In one embodiment, the fastening tabs are bent into the fastening openings in order to obtain a crimped connection.

In one embodiment, the fluid receiving section has at least one fastening web which rests on the respective side of the plate, the at least one fastening web having fastening recesses which are aligned with the fastening openings, and the fastening openings and the fastening recesses being penetrated in pairs by fastening rivets, or the fastening web is connected to at least one of the plate sides by screws and/or by clinching.

In one embodiment, the fastening apertures are formed exclusively in the top side of the panel, exclusively in the bottom side of the panel, or in both the top and bottom sides of the panel.

This achieves the advantage that the fastening of the fluid collector can be functionally decoupled from the heat exchanger formed within the plate-shaped hollow channel body, so that the geometry of the structures formed within the plate-shaped hollow channel body, in particular the heat exchanger, cannot be restricted by the fastening.

In one embodiment, the plate-shaped hollow channel body has hollow channels in which the fluid hollow channels are formed, in particular extruded, and the fastening openings break through the respective plate side towards the hollow channels, in particular on the side of the fluid hollow channels.

The plate-shaped hollow channel body can be extruded with the hollow channels and fluid hollow channels, so that the production of the heat exchanger formed by the fluid hollow channels can be implemented particularly efficiently. Production by means of extrusion achieves the advantage that the plate-shaped hollow channel body can be manufactured in one piece with the hollow channels and fluid hollow channels.

In one embodiment, at least one fluid seal is arranged between the end face and the fluid receiving section for fluid-tight connection of the fluid receiving section to the fluid hollow channels.

Due to the fluid-tight closure of the fluid hollow channels at the respective fluid outlet opening of the fluid hollow channels by means of the fluid seal, the fluid hollow channels can be charged with a fluid without the fluid escaping between the fluid outlet openings and the fluid collector. Thus, the fluid hollow channels and the fluid receiving section can be part of a closed fluid circuit. The fluid-tight closure can in particular be gas-tight and/or liquid-tight.

The fluid seal can be made of an elastic polymer or rubber and can be designed, for example, as an O-ring, X-ring or D-ring.

In one embodiment, the fluid discharge channel runs along the end face and is designed to discharge the fluid transversely to a fluid flow direction in the respective hollow fluid channel.

This achieves the advantage that a plurality of hollow fluid channels running in parallel can be fluidically connected to the fluid discharge channel, so that fluid flowing from the hollow fluid channels into the fluid discharge channel can be discharged particularly efficiently. Advantageously the fluid discharge channel has a cross-sectional area which corresponds to or is larger than the total cross-sectional area of the fluid outlet openings of the fluid hollow channels, so that a constant volume flow of the fluid through the fluid hollow channels and the fluid discharge channel is realized.

In one embodiment, the fluid discharge channel has a tubular or cylindrical shape.

A fluid-tight connection at the ends of the fluid discharge channel can advantageously be realized by a cylindrical shape of the fluid discharge channel. In particular, fluid-tight connections can be efficiently implemented with, for example, screw-in sockets or plug connectors.

In one embodiment, the fluid discharge channel is arranged below the fluid receiving section in terms of fluid flow or above the fluid receiving section in terms of fluid flow.

This achieves the advantage that a fluid discharge channel offset in terms of fluid flow achieves the advantage of particularly efficient fluid transport, since a fluid can flow from the fluid receiving section into the fluid discharge channel as a result of a hydrostatic pressure difference and/or driven by gravity.

In one embodiment, the fluid discharge channel runs at least in sections below or above the plate-shaped hollow channel body.

This achieves the advantage that the installation space of the battery carrier can be advantageously reduced in the longitudinal direction of the fluid hollow channels through the fluid discharge channel.

In one embodiment, the fluid receiving section has a first fluid receiving channel and a second fluid receiving channel, wherein the first fluid receiving channel connects the first fluid outlet opening to the fluid discharge channel, and wherein the second fluid receiving channel connects the second fluid outlet opening to the fluid discharge channel.

In particular, the respective fluid receiving channel implements a flexible, in particular angled, fluid-carrying connection for the fluid flowing through the hollow fluid channels, so that the fluid discharge channel can be arranged in a variable geometric position with respect to the hollow fluid channels.

In one embodiment, the first fluid receiving channel is connected to the first fluid outlet opening in a fluid-carrying manner, and the second fluid receiving channel is connected to the second fluid outlet opening in a fluid-carrying manner.

This achieves the advantage that fluid escaping from the respective fluid outlet openings can be guided particularly effectively through the respective fluid receiving channel. The fluid receiving channels can be designed as a continuous fluid receiving channel connecting all fluid outlet openings.

In one embodiment, the first fluid receiving passage is perpendicular or angled with respect to the first fluid passage and the second fluid receiving passage is perpendicular or angled with respect to the second fluid passage.

This achieves the advantage that a fluid flowing through the hollow fluid channels can flow particularly efficiently into the fluid discharge channel and/or a fluid-carrying connection between the hollow fluid channels and the fluid discharge channel can be realized with a reduced installation space of the fluid collector.

In one embodiment, the fluid discharge channel is arranged below the fluid receiving section in terms of fluid flow, the first fluid receiving channel having a first lateral fluid receiving opening, which is aligned with the first fluid outlet opening, the second fluid receiving channel having a second lateral fluid receiving opening, which is aligned with the second fluid outlet opening, and wherein the first fluid receiving channel and the second fluid receiving channel open into the fluid discharge channel.

In one embodiment, the fluid receiving section has an outer wall facing away from the end face, which is arranged parallel to a surface of the end face and flatly closes off the plate-shaped hollow channel body at the end face.

In one embodiment, the fluid receiving section encompasses the plate-shaped hollow channel body at least partially in the manner of a groove.

This achieves the advantage that a form-fitting connection can be realized between the fluid receiving section and the plate-shaped hollow channel body. In particular, the bearing surface between the fluid receiving section and the plate-shaped hollow channel body can thus be advantageously enlarged.

In one embodiment, the fluid hollow channels are located below the top plate side and are thermally coupled to the top plate side.

This achieves the advantage that the hollow fluid channels can form the heat exchanger. An electric battery arranged on the upper side of the plate, which can be thermally coupled to the upper side of the plate, can give off heat to a fluid flowing in the fluid hollow channels by thermal conduction of the plate-shaped hollow channel body designed to be thermally conductive. By arranging the fluid hollow channels on the upper side of the plate, the distance between the fluid and the electrical battery module can advantageously be reduced. A smaller distance to be bridged by thermal conduction improves the heat transport between the fluid and the electric battery.

In one embodiment, the fluid collector and/or the plate-shaped hollow channel body are each formed in one piece, or the plate-shaped hollow channel body is formed in several parts, and the fluid collector and/or the plate-shaped hollow channel body are extruded in particular from a metal.

This achieves the advantage that the plate-shaped hollow channel body can be produced in a particularly cost-efficient manner with advantageously reduced manufacturing effort and/or advantageously reduced manufacturing time. For the connection of the individual components in the case of a one-piece production, a connection can already be realized after the extrusion and is not realized subsequently, for example by screw and/or clamp connections and/or moulding.

In one embodiment, the fluid discharge channel has a fluid connector on the side in order to discharge the fluid from the fluid discharge channel.

This achieves the advantage that the fluid collector can be connected to a fluid-carrying circuit, in particular a cooling and/or heating circuit, via the fluid discharge channel.

According to a second aspect, the disclosure relates to a cooling system for a vehicle, with a fluid-carrying cooling circuit, wherein a vehicle radiator for cooling a vehicle drive is arranged in the cooling circuit, and the battery carrier is fluidically connected to the fluid-carrying cooling circuit, so that the Heat exchanger with at least a part of the fluid of the fluid-carrying cooling circuit can flow through in order to control the temperature of the electric battery module.

This achieves the advantage that for temperature control, in particular heating and/or cooling, the electric battery module, the battery carrier can be integrated into an existing cooling circuit in the vehicle and thus the temperature control of the electric battery module can be realized by advantageously saving components.
