The fan is arranged as a radial fan, and channels extend through the storage module, e.g., axially, open into a spatial region which is delimited by a cover part of the energy store connected to the storage module and the storage module. The cover part has a recess extending through the cover part, e.g., axially, which is covered by the fan, e.g., by the suction region of the fan, e.g., on the side of the cover part facing away from the storage module, and the energy store has a deflection hood, e.g., for deflecting the conveyed air flow in the axial direction, on the side of the cover part facing away from the storage module. ## Claims ### Claim 1 An energy store, comprising: a storage module; a cover part connected to the storage module; a deflection hood arranged on a side of the cover part facing away from the storage module; and a radial fan; wherein channels extending through the storage module open into a spatial region delimited by the cover part and the storage module; wherein a recess extends through the cover part and is covered by the fan; and wherein a clear diameter of each of the channels varies periodically in an axial direction within the storage module. ### Claim 2 (depends on 1) The energy store according to claim 1, wherein the channels extend axially through the storage module, the recess extends axially through the cover part, the recess is covered by a suction region of the fan on a side of the cover part facing away from the storage module, the deflection hood is adapted to deflect a conveyed air flow in an axial direction that is parallel to a longitudinal axis of the storage module. ### Claim 3 (depends on 1) The energy store according to claim 1, wherein the deflection hood is adapted to deflect an air flow, conveyed by the fan, in an axial direction to flow along an outside of the storage module. ### Claim 4 (depends on 1) The energy store according to claim 1, wherein an air baffle plate of the deflection hood is adapted to deflect an air flow, conveyed by the fan, in an axial direction to flow along an outside of the storage module. ### Claim 5 (depends on 1) The energy store according to claim 1, wherein the deflection hood is connected to the storage module and/or the cover part. ### Claim 6 (depends on 1) The energy store according to claim 1, wherein the deflection hood protrudes laterally over the storage module, so that air flow emerging between the storage module and the deflection hood exits in the axial direction. ### Claim 7 (depends on 1) The energy store according to claim 1, wherein the deflection hood protrudes laterally over the storage module, so that air flow emerging between the storage module and an air baffle plate of the deflection hood exits in the axial direction. ### Claim 8 (depends on 1) The energy store according to claim 1, wherein the channels are spaced apart from one another and/or extend in parallel to each other. ### Claim 9 (depends on 1) The energy store according to claim 1, wherein an air flow exiting from the fan flows into a second spatial region delimited by the deflection hood and the cover part, and an outlet opening is provided between the deflection hood and the storage module. ### Claim 10 (depends on 1) The energy store according to claim 1, wherein an air flow exiting from the fan flows into a second spatial region delimited by the deflection hood and the cover part, and an outlet opening is provided between the deflection hood and the storage module to exit conveyed air flow from the second spatial region into the surroundings. ### Claim 11 (depends on 9) The energy store according to claim 9, wherein an air flow conveyed by the fan flows through the channels in an opposite direction to a through-flow direction of the outlet opening. ### Claim 12 (depends on 1) The energy store according to claim 1, wherein an axis of rotation of the fan is aligned in parallel to an axial direction of the energy store. ### Claim 13 (depends on 1) The energy store according to claim 1, wherein the deflection hood is arranged as a stamped-bent, sheet metal part and an air baffle of the deflection hood plate is arranged an angled region of the deflection hood. ### Claim 14 (depends on 1) The energy store according to claim 1, wherein the fan includes an outlet opening for an emerging air flow, and a circumferential angular range overlapped by the outlet opening overlaps and/or includes a circumferential angular range covered by the outlet opening. ### Claim 15 (depends on 1) The energy store according to claim 1, wherein the fan includes an outlet opening for an emerging air flow through which the air flow conveyed by the fan exits radially, and a circumferential angular range overlapped by the outlet opening overlaps and/or includes a circumferential angular range covered by the outlet opening. ### Claim 16 (depends on 1) The energy store according to claim 1, wherein the storage module includes modules arranged in succession in the axial direction, and the clear diameter of each channel has a maximum value in a connecting region of two respective modules.
