Heat Transfer and Flow Characteristics of Water Flow

A polyethylene tube can be used as a heat exchanger for a low-running-cost temperature control system. In this system, the flow of temperature-controlled water in the tube is used as the heat source, and the tube is placed on the ceiling of a temperature-controlled space using a metal net. Owing to this structure, the tube is deformed by its weight.
