The research team developed a new SWHE that PE tube with winding copper rod for improvement of heat exchanging performance. The new SWHE contains PE tube 16A, length 18.2m, 2.25φ winding copper rod pitched 4mm. This tube has two improvements that 1) the durability maintain 2) the conductivity increasing. We conduct an experiment on heat exchange for two samples that 1) the new sample 2) the existing PE tube in the thermal bath, and we compare two samples. The experiment result that the cooling range of new SWHE is approximately 0.5℃ lower than the existing PE tube system in the approximately 20℃ water bath. There is a requirement that the test bed experiment of a new SWHE in the real condition. |
