Abstract
The present invention provides a heat exchanger for changing the state of a fluid, particularly an evaporator for an air conditioning installation, comprising finned tubular circuits, a fluid distributor device for distributing fluid to the inlets of the tubular circuits through appropriate tubes, and a fluid collector device connecting the outlets of the tubular circuits to an exhaust tube through connecting tubes. The outlets of the tubular circuits are connected to the exhaust tube through a single manifold member formed from two plates superimposed upon each other, with at least one of these plates having projecting portions on one of its faces forming hollow conduits and passages. The invention is particularly applicable to automotive vehicles.
