Patent abstract
A heat exchanger has a heat exchange part that includes a heat supply medium channel with at least one heat supply passage and a heat recovery medium channel surrounding the heat supply medium channel. The heat exchange part is arranged such that, during operation, a heat supply medium passing through the heat supply medium channel exchanges heat with a heat recovery medium passing through the heat recovery medium channel. Cross-sectional space available to accommodate heat recovery medium flow in different sections of the heat recovery medium channel varies according to an amount of heat to be transferred from the heat supply medium to the heat recovery medium in each of the different sections.
