Energy-Storage Housing Having a Cooling Connection, Energy-Storage Unit and Motor Vehicle Having Such An Energy Storage Unit

An energy-storage housing has a cooling connection and a coolant distributor for channeling coolant or refrigerant in the interior of the energy-storage housing. The cooling connection has: at least one connection-pipe component, which is fitted on the coolant distributor; at least one sealing-pipe component, which passes through a wall of the energy-storage housing such that a gap which surrounds the sealing-pipe component remains between the sealing-pipe component and a wall opening; and an attachment, having at least one attachment-pipe component. The connection-pipe component, the sealing-pipe component and the attachment-pipe component are components which can be fitted one on the other and, in the fitted-together state, form a pipe via which it is possible to reach the coolant distributor, for coolant or refrigerant circulation, from outside the energy-storage housing. The attachment can be positioned on the sealing-pipe component and the gap from the outside, the attachment therefore closing the gap.
