PROBLEM TO BE SOLVED: To provide a cooling and heating structure which can cool single cells constituting a battery pack efficiently, and can heat the single cells to a proper temperature range in a short time before starting use even in a cold district.SOLUTION: In the cooling and heating structure, a plurality of flat rectangular parallelepiped single cells 1, and a plurality of planar heat pipes 2 are arranged in lamination so that the single cells 1 and planar heat pipes 2 are perpendicular, and the planar heat pipes 2 come into thermal contact with at least single side of the single cells 1. Upper end of the planar heat pipe 2 at the perpendicular body portion 5a of a base plate 5 is located above the upper end of the single cell 1, and the lower end is located below the lower end of the single cell 1. A horizontal heat radiation part 8 making a right angle to the body portion 5a is provided at the upper end of the body portion 5a, and a horizontal heat receiving part 9 making a right angle to the body portion 5a is provided at the lower end of the body portion 5a. |
