Abstract

A coolant-collecting device in a battery coolant distribution system for a vehicle has at least two flexible coolant-collecting tubes and a T-shaped connecting piece with three tubular connecting elements. The T-shaped connecting piece is arranged between the flexible coolant-collecting tubes, and a first of the three tubular connecting elements can be accommodated in a coolant channel of a battery cooling profile. There is also described a method for producing a coolant-collecting device in a battery coolant distribution system and a vehicle with a battery and a battery coolant distribution system.

First claim

The invention claimed is:

1 . A battery coolant distribution system for a vehicle, the battery coolant distribution system comprising:
a battery cooling profile having a coolant channel extending therein, and a cooling profile plate fixedly connected to said battery cooling profile; a coolant-collecting device having:
at least two flexible coolant-collecting tubes;
a T-shaped connecting piece with three tubular connecting elements;
said T-shaped connecting piece being arranged between said flexible coolant-collecting tubes, and a first of said three tubular connecting elements, which is oriented perpendicularly to the other said tubular connecting elements, being configured to be received in said coolant channel of said battery cooling profile, said T-shaped connecting piece including a fastening unit for fastening said T-shaped connecting piece onto said cooling profile plate, and said fastening unit having a screw point for screwing said fastening unit to said cooling profile plate; and
said flexible coolant-collecting tubes having a cross section compatible with a cross section of two opposite second and third connecting elements of said three tubular connecting elements and being connected to said second and third connecting elements; and
said screw point of said fastening unit being integrally connected to a T-shaped connecting piece of said coolant-collecting device and being a tongue-shaped protrusion formed with a screw hole.

2 . The battery coolant distribution system according to claim 1 , wherein said coolant-collecting device comprises a sealing element for sealing between said first tubular connecting element and the coolant channel.

3 . The battery coolant distribution system according to claim 2 , wherein said sealing element comprises an O-ring.

4 . The battery coolant distribution system according to claim 1 , wherein said flexible coolant-collecting tubes are fastened to said T-shaped connecting piece by way of a releasable fastening unit.

5 . The battery coolant distribution system according to claim 4 , wherein said releasable fastening unit is a hose clamp.

6 . The battery coolant distribution system according to claim 1 , wherein said coolant-collecting device comprises:
a plurality of T-shaped connecting pieces; at least three flexible coolant-collecting tubes connected in series to one another by way of said plurality of T-shaped connecting pieces.

7 . The battery coolant distribution system according to claim 1 , wherein said first tubular connecting element of said three tubular connecting elements of said T-shaped connecting piece of said coolant-collecting device is inserted into said coolant channel of said battery cooling profile.

8 . The battery coolant distribution system according to claim 7 , further comprising a connection line for connection to a cooler system, wherein said connection line is connected directly to an outer of said flexible coolant-collecting tubes.

9 . The battery coolant distribution system as claimed in claim 7 , wherein the direct connection is formed by a quick coupling between the outer flexible coolant-collecting tube and the connection line.

10 . A method for producing a battery coolant distribution system, the method comprising:
forming a T-shaped connecting piece having three tubular connecting elements with a first of the three tubular connecting elements, which is oriented perpendicularly to second and third tubular connecting elements of said three tubular connecting elements, being configured to be received in a coolant channel of a battery cooling profile having a cooling profile plate fixedly connected to the battery cooling profile; forming at least two flexible coolant-collecting tubes having a cross section compatible with a cross section of the second and third connecting elements of the three tubular connecting elements, wherein the T-shaped connecting piece includes a fastening unit for fastening the T-shaped connecting piece onto the cooling profile plate and the fastening unit includes a screw point for screwing the fastening unit to the cooling profile plate; wherein the screw point is integrally connected to a T-shaped connecting piece of the coolant-collecting device and forms a tongue-shaped protrusion with a screw hole; arranging the T-shaped connecting piece between the flexible coolant-collecting tubes; connecting the second and third connecting elements of the T-shaped connecting piece to the flexible coolant-collecting tubes; and inserting the first of the three tubular connecting elements of the T-shaped connecting piece into the coolant channel of the battery cooling profile.

11 . A vehicle, comprising an electric battery and a battery coolant distribution system according to claim 1 .
