    • PROBLEM TO BE SOLVED: To provide an underground heat exchanger capable of high efficiency heat exchange without pumping up underground water to the ground.SOLUTION: An underground heat exchanger includes: a fluid blowing tube; fluid pumping means; and pressure adjusting means. The fluid blowing tube is a tubular member contained in a space within a casing, and is provided to penetrate a lid member and to reach a depth of a bottom portion of a heat exchange unit (that is, depth of a mesh part provided in a lower end portion of the casing). This fluid blowing tube includes a fluid jet opening. This fluid jet opening is formed to blow a fluid such as air into underground water in the space inside of the casing by jetting the fluid near the bottom portion of the heat exchange unit.
    • 要解决的问题:提供一种能够高效地进行热交换的地下热交换器,而不需要将地下水泵送到地面。地下热交换器包括:流体吹管; 流体泵送装置; 和压力调节装置。 流体吹送管是容纳在壳体内的空间中的管状构件,设置成贯通盖构件并到达热交换单元的底部的深度(即,设置在 壳体的下端部)。 该流体吹送管包括流体喷射口。 该流体喷射口形成为通过喷射靠近热交换单元的底部部分的流体将诸如空气的流体吹入壳体内的空间中的地下水中。
