Collecting box for heat exchanger, has pipes constituted by superposition in alternation of spacer walls and cap walls that have cutout passages superimposing on cutout passages of spacer walls

摘要

The box has extended pipes (2) aligned parallelly one on another. The pipes are constituted by a superposition in alternation of cap walls (4) and spacer walls (6). The cap walls have cutout passages (10) and cutout housings (12). The cutout passages of the cap walls superimpose on cutout passages (8) of the spacer walls for forming a fluid channel. An Independent claim is also included for a heat exchanger.
