HEAT EXCHANGER DEVICE USING PRECAST PILE AND PRECAST PILE WITH HEAT EXCHANGING PIPES

摘要

PROBLEM TO BE SOLVED: To facilitate a connecting work for precast pile*heat exchanging pipes without any possibility of damaging heat exchanging pipes at the time of their burying work.SOLUTION: A first heat exchanging pipe 10 and a linear second heat exchanging pipe 20 are installed within an intermediate precast pile 30 in such a way that linear pipe pieces 11 to 13 are bent to be included within them. A first A connecting port 1a is formed at an opening of one end 31 of the first heat exchanging pipe 10 and a first B connecting port 1b is formed at the other end 32. A second A connecting port 2a is arranged at one end 31 of the second heat exchanging pipe 20 and a second B connecting port 2b is formed at the other end 32. A third heat exchanging pipe 40 is arranged within the lower-most precast pile 50. Upside-down intermediate precast pile 30B is connected on the lower-most precast pile 50 and an intermediate precast pile 30A is connected on it and each of the pipes is connected to each other. The first A connecting port 1a and the second A connecting port 2a of the uppermost intermediate precast pile 30 are connected to fluid circulation*heat recovery means to form a heat exchanging device.SELECTED DRAWING: Figure 1
