Abstract

A cooling arrangement for a battery box includes a plate-shaped heat exchanging element, a cooling channel secured to the heat exchanging element, and a fluid collector for collecting or feeding a fluid into the cooling channel. The fluid collector includes a volume region and has a receiving opening on a side proximate to the cooling channel for introduction of the cooling channel to thereby fluidly connect the volume region with the cooling channel. A sealing element and a clamping element are arranged on an outside of the fluid collector at the receiving opening, with the clamping element being traversed by the cooling channel. A clamping tab is arranged above or below the receiving opening in surrounding relationship to the sealing element and the clamping element to thereby secure the cooling channel immovably to the fluid collector.

First claim

What is claimed is:

1. A cooling arrangement for a battery box, said cooling arrangement comprising:
a plate-shaped heat exchanging element;
a cooling channel secured to the plate-shaped heat exchanging element;
a fluid collector for collecting or feeding a fluid into the cooling channel, said fluid collector including a volume region and having a receiving opening on a side proximate to the cooling channel for insertion of the cooling channel to thereby fluidly connect the volume region with the cooling channel;
a seal arranged on an outside of the fluid collector at the receiving opening;
a clamping element arranged on the outside of the fluid collector at the receiving opening and traversed by the cooling channel;
a clamping tab arranged above or below the receiving opening in surrounding relationship to the seal and the clamping element to thereby secure the cooling channel immovably to the fluid collector; and
a fishplate formed hi one piece with and made of same material as the fluid collector for connecting the fluid collector with the plate-shaped heat exchanging element.

2. The cooling arrangement of claim 1 , wherein the cooling channel is connected to the plate-shaped heat exchanging element by a form fit and/or material joint.

3. The cooling arrangement of claim 1 , further comprising a holder formed in one piece with and made of same material as the plate-shaped heat exchanging element for receiving the cooling channel.

4. The cooling arrangement of claim 1 , wherein the volume region has a cross section which is round or polygonal or varies over a length of the volume region.

5. The cooling arrangement of claim 1 , wherein the fluid collector is made in one piece and uniformly produced of an aluminum alloy.

6. The cooling arrangement of claim 1 , wherein the clamping tab, the fishplate, and the receiving opening are produced by mechanically processing an extruded profile.

7. The cooling arrangement of claim 1 , further comprising an end piece attached to an end of the fluid collector to close off the fluid collector.

8. The cooling arrangement of claim 1 , wherein the volume region has a variable diameter or with a variable cross sectional configuration.

9. The cooling arrangement of claim 5 , wherein the fluid collector is produced by an extrusion process.

10. The cooling arrangement of claim 1 , wherein the seal is made of a malleable material selected from the group consisting of elastomer, polymer, and another fluidtight and gastight material.

11. The cooling arrangement of claim 1 , wherein the clamping element is made of a stiff material which is fluidtight and gastight.

12. The cooling arrangement of claim 1 , wherein the cooling channel is secured to the fluid collector by a press fit.

13. The cooling arrangement of claim 12 , wherein the press fit is formed between the cooling channel and the seal.

14. The cooling arrangement of claim 1 , wherein the seal is arranged at the receiving opening and surrounded by the clamping element, with the clamping element and a wall of the fluid collector in surrounding relationship to the receiving opening defining a hollow space in which the seal is arranged.

15. The cooling arrangement of claim 1 , wherein the seal and the clamping element jointly form a single-piece structure.

16. A cooling arrangement for a battery box, said cooling arrangement comprising:
a plate-shaped heat exchanging element;
a cooling channel secured to the plate-shaped heat exchanging element;
a fluid collector for collecting or feeding a fluid into the cooling channel, said fluid collector including a volume region and having a receiving opening on a side proximate to the cooling channel for insertion of the cooling channel to thereby fluidly connect the volume region with the cooling channel;
a seal arranged on an outside of the fluid collector at the receiving opening;
a clamping element arranged on the outside of the fluid collector at the receiving opening and traversed by the cooling channel;
a clamping tab arranged above or below the receiving opening in surrounding relationship to the seal and the clamping element to thereby secure the cooling channel immovably to the fluid collector, and
an end piece attached to an end of the fluid collector to close off the fluid collector, wherein the end piece includes a connecting portion having a threaded sleeve and attached to the end of the fluid collector, said fluid collector comprising a further clamping tab to hold the connecting portion captivated, said end piece further including a fitting for connection to a fluid supply line or fluid discharge line, said fitting being threadably engaged via the threaded sleeve to the connecting portion.
