Heat transmitter of parallel flat tubes fits open tube ends into contour-matched manifold for fluid transfer steadying tubes by outside and center stays.

摘要

At one end (8) the several flat tubes (2) in the heat transmitter (1) are fed with fluid (F) via a manifold (6). The tubes fit positively into the manifold, each having a recess in the outside contour (10) of the tube which matches that of the manifold. The tube (1) end (9) has several openings (13) and the tube end contour (10) can be open, the tube fitted with outside stays and one tube at least has a center stay. The inside contour (12) of the tube (8) has an opening (14) and this end can be materially joined to the manifold. Preferred use is vehicle air conditioning.
