Wärmetauscher mit einer Mehrzahl von Rohrelementen

摘要

The heat exchanger has an inlet insert (11a) and an outlet insert (11b) for a fluid, where a set of pipe units (20) is arranged between the inlet and outlet inserts. A hollow space is formed between the pipe units, and another fluid is flowable in the hollow space. The pipe units with changeable radius of curvature are wound in a spiral form around a bearing shaft (23). Another set of pipe units is wound in another spiral form, where the latter spiral form is arranged inside the former spiral form for formation of a dual spiral.
