<p>PROBLEM TO BE SOLVED: To effectively cool the inside of an electric power element, and to effectively prevent burst by refinforcing the outer can of the electric power element. SOLUTION: This power source module has an electric power element 2 that is, a battery or a capacitor, and a heat radiating sleeve 9 for inserting the electric power element 2. The heat radiating sleeve 9 has an inserting hole 18A for inserting the outer can 2a of the electric power element 2, and a heat radiating fin 17 projecting from the surface of the heat radiating sleeve 9. This power source device internally stores the power source module 1 having the heat radiating sleeve 9 in a housing chamber 11 of a case 10. The heat radiating sleeve 9 has the inserting hole 18A for inserting the outer can 2a of the electric power element 2, and the heat radiating fin 17 projecting from the surface of the heat radiating sleeve 9. The power source device sends cooling air to the housing chamber 1, and cools the power source module 1 built in the housing chamber 11.</p> |
