Abstract

Some embodiments of the present disclosure relate to technical field of the battery cooling technical and provide a battery cooling assembly, including: a cooling tube; a collecting tube, provided with at least one collecting opening; a connecting aid, including a base plate provided with a through hole, and a hole wall of the through hole extends outwardly to form an extension. An end of the cooling tube is connected to the extension through the through hole, the base plate is connected with the collecting tube, and the through hole being in communication with the collecting opening. The battery cooling assembly of the present disclosure can increase the connection strength between the cooling tube and the collecting tube, thereby reducing a risk of leakage of a cooling medium.

First claim

What is claimed is:

1. A battery cooling assembly, comprising:
a cooling tube;
a collecting tube, comprising a top wall, a bottom wall, and two side walls, wherein:
a collecting opening is provided in one of the two side walls;
an opening edge of the collecting opening comprises a top edge, a bottom edge, and two side edges; and
the bottom edge of the collecting opening is in contact with an inner surface of the bottom wall; and

a connecting aid, comprising a base plate provided with a through hole, and a hole wall of the through hole extending outwardly to form an extension, wherein the extension abuts against the bottom edge of the collecting opening, and the extension is configured to:
extend through the collecting opening beyond the one of the two side walls and into the collecting tube, and
be in direct contact with the inner surface of the bottom wall;

wherein an end of the cooling tube is connected to the extension through the through hole, the base plate is connected with the collecting tube, and the through hole is in communication with the collecting opening.

2. The battery cooling assembly according to claim 1 , wherein the extension extends one-way along an axis of the through hole.

3. The battery cooling assembly according to claim 2 , wherein the extension extends into the collecting opening.

4. The battery cooling assembly according to claim 3 , wherein the extension has a tubular structure.

5. The battery cooling assembly according to claim 4 , wherein a cross-sectional shape of the extension matches a shape of the collecting opening, and the extension extends through the collecting opening into a collecting passage of the collecting tube.

6. The battery cooling assembly according to claim 1 , wherein:
the hole wall of the through hole comprises a top hole wall, a bottom hole wall and two side hole walls; and
the extension is formed through extension of the bottom hole wall.

7. The battery cooling assembly according to claim 6 , wherein—a distance between the top edge of the collecting opening and the top wall is greater than a distance between the bottom edge of the collecting opening and the bottom wall.

8. The battery cooling assembly according to claim 1 , wherein the base plate comprises a first surface and a second surface, the extension is formed on the second surface, and a chamfer is provided at a through hole of the first surface.

9. The battery cooling assembly according to claim 5 , wherein the extension is formed when the through hole is punched on the base plate by a stamping process.

10. The battery cooling assembly according to claim 1 , wherein the extension extends into the collecting opening.

11. The battery cooling assembly according to claim 1 , wherein the extension has a tubular structure.

12. The battery cooling assembly according to claim 1 , wherein a cross-sectional shape of the extension matches a shape of the collecting opening, and the extension extends through the collecting opening into a collecting passage of the collecting tube.

13. The battery cooling assembly according to claim 1 , wherein the extension is formed when the through hole is punched on the base plate by a stamping process.
