PROBLEM TO BE SOLVED: To provide a refrigeration structure capable of efficiently cooling an electric cell constituting a battery pack.SOLUTION: A refrigeration structure includes: a plurality of flat electric cells 1 to be arranged vertically; a plurality of heat pipes 2 having a substrate 3 on which a heat pipe part 4 is disposed; an outer case 5 for housing an electric cell 1 and a heat pipe 2; and a refrigeration device 6 mounted on an outer face of an upper wall 5a for the outer case 5. A substrate 3 of the heat pipe 2 includes: a vertical heat receiving part 8 thermally contacted with at least a single side of the electric cell 1; and a horizontal heat radiation part 9 continuously disposed from the heat receiving part 8 so as to project upper than the electric cell 1 and forming a right-angle with the heat receiving part 8. The heat pipe part 4 is disposed from the heat receiving part 8 to the heat radiation part 9 of the substrate 3. The heat radiation part 9 of the substrate 3 is fixed after having it aligned to the inner face of the upper wall 5a for the outer case 5, and the refrigeration device 6 is mounted on the outer surface of the upper wall 5a of the outer case 5. |
