When the ambient temperature increases, the voltage V1 on one side of the thermistor 16 becomes lower than the reference voltage VS set as the reference temperature, so that the output of the comparator 21-1 increases and the base of the transistor 22-1 and the transistor 24-1. 1 operates so that a current flows through the base of the transistor 1 and the collector voltage of the transistor 24-1 decreases.

０−１，１０−２の外側にある空気と熱交換を行う。At this time, since the output of the comparator 21-2 is low, no current flows through the base of the transistor 22-2 and the base of the transistor 24-2, so that the collector voltage of the transistor 24-2 increases. Works. Accordingly, current flows from the connector 13 in the direction B.
At this time, the electron heating / cooling element 8 is an N-type semiconductor, and the electron heating / cooling element 9 is a P-type semiconductor. Heat is absorbed at the junction of the metal part 7, and heat is released at the junction of the electronic heating / cooling element 8 and the metal part 10-2 and the junction of the electronic heating / cooling element 9 and the metal part 10-1. As a result, the temperature of the metal part 7 decreases, and the cell 4 inside the heat diffusion part 2 is cooled via the heat conduction part 6 and the heat diffusion part 2 connected thereto. On the other hand, the temperature of the metal parts 10-1 and 10-2 rises,
Since the thermal diffusion unit 2 is thermally insulated, the thermal diffusion unit 2

Operate so that the collector voltage of the first transistor becomes high. Therefore, a current flows from the connector 13 in the direction of A. At this time, the opposite phenomenon occurs when the temperature around the battery unit 1 becomes high, and heat is released in the metal part 7 and heat is absorbed in the metal part 10. As a result, the temperature of the metal part 7 rises, and the cell 4 inside the heat diffusion part 2 is heated via the heat conduction part 6 and the heat diffusion part 2 connected thereto.
