To provide a thermal medium supply device capable of reducing a charging time of a battery and being easily spread.SOLUTION: In the case where a battery 72 is cooled at the time of the charging of a vehicle, a blowout part 26 of a heating medium supply device 10 supplies a heating medium of which an absolute water amount is large against an outer air while having a low temperature against the outer air to an outer air heat exchanger 423. Thus, the blowout part 26 increases a radiation heat amount from a liquid medium in the outer air heat exchanger 423 as compared to the case where the outer air exchanges a heat with the liquid medium in the outer air heat exchanger 423 in replacement of the heating medium. Therefore, since a cooling of the battery 72 is promoted, a charging time of the battery 72 can be reduced. Then, since a vehicle 70 comprises a temperature adjustment device 40 having the outer air heat exchanger 423, the heating medium supply device 10 can be easily spread because the temperature adjustment device 40 does not require a construction dedicated for using the heating medium supply device 10.SELECTED DRAWING: Figure 1 【課題】電池の充電時間を短縮でき且つ普及しやすい熱媒体供給装置を提供する。【解決手段】車両充電の際に電池７２の冷却が行われる場合には、熱媒体供給装置１０の吹出部２６は、外気に対して温度が低く且つ外気に対して絶対水分量が多い熱媒体を外気熱交換器４２３へ供給する。これにより、吹出部２６は、その熱媒体の替わりに外気が外気熱交換器４２３で液媒体と熱交換する場合に比して、外気熱交換器４２３での液媒体からの放熱量を増大させる。従って、電池７２の冷却が促進されるので、電池７２の充電時間を短縮することが可能である。そして、車両７０は、外気熱交換器４２３を有する温調装置４０を備えているが、その温調装置４０は、熱媒体供給装置１０を使用するための専用の構造を備える必要がないので、熱媒体供給装置１０を普及させやすい。【選択図】図１
