Heat exchanger tube with optimized plates

摘要

The invention relates to tubes for heat exchangers through which a fluid flows, intended to promote heat exchange between an external medium and said fluid, formed by at least two plates connected to each other in order to define a circulation duct. The tube comprises a means for partially blocking the circulation duct intended to keep the passage cross section of said duct substantially constant between an inlet orifice and an outlet orifice.The heat exchangers have plate based tubes and are used especially as an evaporator in an air conditioning system or radiator in the cooling circuit of a vehicle.
