Abstract

A coolant discharger for a coolant-carrying pipeline network of an electrical energy storage device has at least one drainage ramp configured to be arranged on a pipeline portion of the pipeline network that is susceptible to a coolant leakage, the drainage ramp is configured to discharge a coolant leaking out from the pipeline portion in the event of a coolant leakage and to divert it away from voltage-carrying components of the electrical energy storage device.

First claim

What is claimed is:

1 . A coolant discharger for a coolant-carrying pipeline network of an electrical energy storage device, comprising:
at least one drainage ramp configured to be arranged on a pipeline portion of the pipeline network that is susceptible to a coolant leakage, wherein the at least one drainage ramp is configured to discharge a coolant leaking out from the pipeline portion in the event of a coolant leakage and to divert the coolant away from voltage-carrying components of the electrical energy storage device.

2 . The coolant discharger according to claim 1 , wherein
the at least one drainage ramp comprises:
a discharge portion sloping obliquely downward and configured to be arranged beneath the pipeline portion susceptible to coolant leakage; and
a wall portion projecting upward from the discharge portion and configured to at least partially encase the pipeline portion.

3 . The coolant discharger according to claim 2 , wherein
the wall portion comprises at least one convex portion configured to receive a sub-region of the pipeline portion.

4 . The coolant discharger according to claim 3 , wherein
the wall portion comprises two convex portions configured to receive two adjacent sub-regions of the pipeline portion.

5 . The coolant discharger according to claim 1 , wherein
the coolant discharger comprises a connection portion configured to mechanically connect the at least one drainage ramp to a storage housing of the electrical energy storage device.

6 . The coolant discharger according to claim 5 , wherein
the connection portion comprises tabs that project laterally from the discharge portion and that each have at least one hole.

7 . The coolant discharger according to claim 1 , wherein
the coolant discharger comprises a holding element configured to hold the at least one drainage ramp on the pipeline portion.

8 . The coolant discharger according to claim 7 , wherein
the holding element comprises a bracket attached in a non-destructively detachable manner to the at least one drainage ramp.

9 . The coolant discharger according to claim 1 , wherein
at least one pipeline element of the pipeline portion susceptible to coolant leakage is attached to the at least one drainage ramp, forming a preassembled assembly.

10 . The coolant discharger according to claim 9 , wherein
the at least one pipeline element comprises a pipe connection element of a pipeline portion susceptible to coolant leakage further comprising a pipeline connection configured to connect two pipelines of the pipeline network, wherein the at least one drainage ramp is attached to the pipe connection element.

11 . An electrical energy storage device for a motor vehicle, having at least one voltage-carrying component, a coolant-carrying pipeline network for cooling the voltage-carrying component and comprising at least one pipeline portion susceptible to a coolant leakage, and at least one coolant discharger according to claim 1 .

12 . A motor vehicle having at least one electrical energy storage device according to claim 11 .
