To provide is sufficient cooling performance compact and with a can exhibit cooling system unit. And the heat radiating member 2, a battery holder 3 for housing a battery 7 provided on the heat radiating member 2, and a heat radiation side Peltier surface 4 and the heat absorption side the Peltier surface 5 and the heat dissipation side Peltier by the action of the cell 7 in the battery housing portion It is configured to cool by heat radiation by the heat radiating member 2 through the surface 4. Is constituted by the heat radiating member 2 is more than one heat dissipating plates 28 which are arranged at intervals, the battery housing portion 3 is, it is constituted by forming a space for accommodating a battery 7 to the radiator plate 28. Moreover, it is provided to pass over the plurality of radiating plates 28, the heat conducting member 30 in contact with the heat radiating plate 28 provided to connect the thermally conductive member 30 to the heat radiating side Peltier surface 4 side of the heat radiation side Peltier face 4 heat through the heat conducting member 30 I is constructed such that heat radiation by the plurality of the heat sink 28.十分な冷却性能を発揮できるとともに小型である冷却装置ユニットを提供する。 放熱体2と、放熱体2内に設けられ電池7を収容する電池収容部3と、放熱側ペルチェ面部4及び吸熱側ペルチェ面部5とを備え、電池収容部内の電池7の作用によって放熱側ペルチェ面部4を介して放熱体2によって放熱して冷却するように構成した。放熱体2が間隔をおいて並べられた複数の放熱板28によって構成され、電池収容部3が、放熱板28に電池7を収容する空間を形成することによって構成してある。また、複数の放熱板28に掛け渡すように設けられ、放熱板28に接触する熱伝導部材30を設け、熱伝導部材30を放熱側ペルチェ面部4側に接続し、放熱側ペルチェ面部4からの熱を熱伝導部材30を介して複数の放熱板28によって放熱するように構成した。
