(57) Abstract :
A roll bond heat exchanger for a Heating, Ventilation and Air-Conditioning system (HVAC) system is disclosed. In one embodiment,
an apparatus includes at least one roll bonded sheet formed using at least two sheets by a roll welding method. The roll bonded sheet
includes a first hollow section, having an inlet and an outlet, for providing a flow passage for a first fluid, and one or more openings
for providing a flow passage for a second fluid such that the second fluid passes along the surface of the at least one roll bonded sheet
and cross across the one or more openings of the at least roll bonded sheet in such a way that heat is transferred between the first fluid
and the second fluid thereby achieving desired thermodynamic state changes in the HVAC system. Figure 1
