Heat exchanger for use in e.g. motor vehicle cooling system, has flat pipes with channels and recesses in longitudinal direction, where channels are perfused by fluid and recesses are formed between channels

摘要

The exchanger has a housing that is perfused by a fluid and comprises an inlet and an outlet. Flat pipes comprise channels (9) and recesses (8) in a longitudinal direction, where the channels are perfused by another fluid and the recesses are formed between the channels. Braces (7) are provided between the pipes, so that sections (11) are formed and the former fluid flows section-wise from the inlet to the outlet.
