Title:
熱交換器用伝熱管、および伝熱管とこれを保持する保持部材とを備えてなる熱交換器
Document Type and Number:
Japanese Patent JP7064551
Kind Code:
B2
Abstract:
To provide a heat transfer pipe that has high corrosion resistance and a low cost, and a heat exchanger with the heat transfer pipes and holding members for holding the heat transfer pipes.SOLUTION: In a heat transfer pipe, a low-temperature fluid flows in the inside, a high-temperature gas flows in the outside, and heat exchange is carried out between the high-temperature gas and the low-temperature fluid when the high-temperature gas contacts with the heat transfer pipe. At least a portion of the heat transfer pipe, which contacts with the high-temperature gas, is formed of fluororesin. A heat exchanger has the heat transfer pipes and holding members that contact with a corrosive gas and have holes for insertion of the heat transfer pipes to hold the same. At least a portion of the holding member, which contacts with the corrosive gas, is formed of the fluororesin.SELECTED DRAWING: Figure 1
