Abstract

Provided is a battery module. The battery module includes: a first cooling pipe; a second cooling pipe connected to the first cooling pipe and arranged on a different plane than the first cooling pipe; and a branch unit connecting the first cooling pipe and second cooling pipe, wherein the branch unit includes: a lower connection pipe connected to the first cooling pipe; an upper connection pipe connected to the second cooling pipe; and a connection member into which one of the lower connection pipe and the upper connection pipe is inserted and which is inserted into the other one of the lower connection pipe and the upper connection pipe.

First claim

The invention claimed is:

1. A battery module comprising:
a first cooling pipe;
a second cooling pipe connected to the first cooling pipe and arranged on a different plane than the first cooling pipe;
a third cooling pipe connected to the first cooling pipe and arranged on a different plane than the first cooling pipe; and
a branch unit connected between at least one selected from the group consisting of:
the first cooling pipe and the second cooling pipe, and
the first cooling pipe and the third cooling pipe,

wherein the branch unit includes:
a lower connection pipe connected to the first cooling pipe and including a lower connection unit;
an upper connection pipe connected to the second cooling pipe or the third cooling pipe and including an upper connection unit; and
a connection member into which one of the lower connection pipe and the upper connection pipe is inserted and which is inserted into the other one of the lower connection pipe and the upper connection pipe, the connection member being between the lower connection unit and the upper connection unit and contacting the lower connection unit and the upper connection unit,
wherein the lower connection unit of the lower connection pipe connected to the upper connection pipe is inclined along a lengthwise direction of the lower connection pipe, and the upper connection unit of the upper connection pipe connected to the lower connection pipe is inclined along a lengthwise direction of the upper connection pipe,
wherein the lower connection unit or the upper connection unit is forcibly fitted into the connection member, and
wherein the lower connection unit or the upper connection unit is shaped so that the lower connection pipe or the upper connection pipe, respectively, has:
an inner surface comprising an inner surface portion exposed to an outside of the lower connection pipe or the upper connection pipe; and
an outer surface opposite to the inner surface and comprising an outer surface portion, opposite to the inner surface portion, that faces the lower connection pipe or the upper connection pipe.

2. The battery module of claim 1 , further comprising a third cooling plate where the third cooling pipe is arranged.
