Title:
熱交換用配管を備えた熱交換システム、及び熱交換用マットの製造方法
Document Type and Number:
Japanese Patent JP7053002
Kind Code:
B2
Abstract:
To provide a heat exchange pipe that can improve a heat exchange rate between a heat exchange medium and a fluid flowing in an existing pipe even when a flow channel of the heat exchange medium is composed of a material whose heat transfer coefficient is relatively low, and to provide a heat exchange mat equipped with the heat exchange pipe, a heat exchange system equipped with the heat exchange pipe, and a manufacturing method of the heat exchange mat.SOLUTION: A heat exchange pipe 20 fixed to the inner wall of an existing pipe 70 buried in the ground, which flows a heat exchange medium that performs heat exchange with a fluid 78 flowing in the existing pipe 70 includes a coating layer 25 on a surface on a side where at least the fluid 78 circulates for increasing heat transfer performance between the heat exchange medium and the fluid 78, which is composed of a material different from a material of a flow channel of the heat exchange medium.SELECTED DRAWING: Figure 2
