HEAT TRANSPORT SYSTEM

PROBLEM TO BE SOLVED: To provide a heat transport system capable of efficiently transporting a heating value even if a pipe connecting a first heat medium exchanger to a second heat exchanger lengthens.SOLUTION: The heat transport system comprises: a first heat exchanger 3 evaporating a liquid heat medium by heat of a heat source; a second heat exchanger 5 condensing the heat medium by cooling the evaporated heat medium; a first pipe 7 circulating the heat medium from the first heat exchanger to the second heat exchanger; a second pipe 9 circulating the heat medium from the second heat exchanger to the first heat exchanger; a reservoir tank 23 provided halfway along the second pipe and storing the heat medium; a check valve 19 provided between the second heat exchanger and the reservoir tank and allowing only a flow in a direction from the second heat exchanger to the reservoir tank; a check valve 21 provided between the reservoir tank and the first heat exchanger and allowing only a flow in a direction from the reservoir tank to the first heat exchanger; and a third heat exchanger 11 provided halfway along each pipe 7, 9 and implementing heat exchange with each pipe. 【課題】第１の熱媒交換器と第２の熱交換器とを接続していている配管の長さが長くなっても、熱量を効率良く移動することができる熱輸送システムを提供する。【解決手段】熱源の熱によって液体の熱媒体を気化させる第１の熱交換器３と、気化した熱媒体を冷却することで熱媒体を凝縮させる第２の熱交換器５と、第１の熱交換器から第２の熱交換器に熱媒体を流す第１の配管７と、第２の熱交換器から第１の熱交換器に熱媒体を流す第２の配管９と、第２の配管の途中に設けられ熱媒体を貯留するリザーブタンク２３と、第２の熱交換器とリザーブタンクの間に第２の熱交換器からリザーブタンク方向への流れのみ許容する逆止弁１９と、リザーブタンクと第１の熱交換器の間にリザーブタンクから第１の熱交換器方向への流れのみ許容する逆止弁２１と、各配管７，９の途中に設けられ各配管の間で熱交換をする第３の熱交換器１とを有する。【選択図】図１
