An underwater heat exchanger is provided to circulate heating medium through a heat exchange pipe for preventing the generation of a dead zone and to generate upward or downward air flow around the heat exchanger by an agitator, thereby achieving heat exchange over the entire area of the heat exchanger for improving heat exchanger efficiency. An underwater heat exchanger includes upper and lower frames(110,120) formed with a plurality of through-holes(11), and vertical frames(130) connecting both ends of the upper and lower frames to each other integrally to form a rectangular structure. An inlet pipe(140) and an outlet pipe(150) are mounted outside the vertical frames in parallel thereto for introducing heating medium circulating a heat pump and returning to the heat pump respectively. A heat exchange pipe(160) connects the inlet pipe to the outlet pipe. The heat exchange pipe is disposed zigzag in the horizontal direction by penetrating the vertical frames, which face each other. An agitator(300) is mounted to either one or both of the upper and lower frames to be driven by a motor to generate upward/downward stream around the heat exchange pipe when heating/cooling is carried out by the heat pump, wherein the agitator has a fan for inducing water to flow vertically. |
