Radiating member for laminated battery and method of manufacturing the same
First Claim
1. A radiating member for a laminated cell, covered with a laminate material, which is in contact with a surface of said laminated cell to radiate heat produced by said laminated cell, characterized in that:
- said radiating member has a plurality of first wall, and a plurality of second flat wall connected to said first wall and arranged substantially at right angles to said first wall, wherein at least one of said second wall is arranged for close contact with a sheathed surface of said laminated cell.

Abstract
A radiating member (2) of the present invention comprises a plurality of first wall (2a), and a second wall (2b) connected to the first wall (2a) and formed substantially at right angles to the first wall (2a), which are alternately and continuously formed. The first wall (2a) are arranged substantially perpendicular to the surface (1d) of a laminated cell (1) such that they are not collapsed by loads applied from the top and bottom surfaces of the laminated cells (1). The second wall (2b) make up a flat plane substantially parallel with the surface (1d) in order to gain a heat transfer area and uniformly apply the loads to the laminated cell (1). To ensure a largest possible area for the second wall (2b), R-sections (2c), which connects the second wall (2b) with the first wall (2a), are formed to have a smallest possible radius.

12. A method of manufacturing a radiating member for a laminated cell, which is in contact with a surface of said laminated cell covered with a laminate material for radiating heat generated by said laminated cell, characterized by having:
-
a step of providing a metal-made plate member having a rectangular-wave shape in cross-section, said plate member having a first wall, a second flat wall connected to one end side of said first wall and arranged substantially at right angles to said first wall, and a third flat wall connected to the other end side of said first wall and arranged substantially at right angles to said first wall;
a cutting step of cutting said first wall and said second wall, without cutting said third wall, at a predetermined cutting position in a longitudinal direction of said first wall, said second wall, and said third wall; and
a bending step of bending said third wall, which is not cut in said cutting step at the cutting position, until said third wall opposes each other. - View Dependent Claims (13)
