HEAT EXCHANGER, AND REACTOR AND RADIATION HEATER USING THE HEAT EXCHANGER

WIPO Patent Application WO/2004/010068

A1

An autothermal-type heat exchanger where larger heat transmission area is achievable in spite of a limited capacity, relatively easy to produce, and provides vast improvement in heat exchange efficiency. A heat exchanger having a partition wall-type heat transmission body (BF) for partitioning a high temperature fluid (1) and a low temperature fluid (2) is characterized as follows. The heat transmission body (BF) has a bellows shape and formed such that both fluids (1, 2) flow in gaps in the bellows portion of the heat transmission body (BF) in the directions opposed to each other along ridge lines or valley lines of the bellows portion. At one end or both ends of the heat transmission body (BF) at which one end or both ends the ridge lines of the bellows portion intersect, there is provided a flow-around space portion(s) (F) for causing one of the fluids to flow around into the gaps of the bellows portion on the opposite side. Heat is exchanged such that one of the fluids that flow around into the opposite side through the flow-around portion(s) (F) becomes the other fluid whose heat is to be exchanged.
