A heat exchanger, in particular for a heating or air-conditioning system in a motor vehicle, having an evaporator unit to which a refrigerant medium can be supplied via a distribution unit and through which said refrigerant medium flows and around which said refrigerant medium flows after only one diversion (two-block design) at the bottom in a diversion unit, wherein the distribution unit is designed to effect a uniform distribution of the refrigerant medium over the full width of the evaporator.

Heat exchanger for vehicle with two block design

A total evaporator for fluids, including a cold chamber to prevent pre-evaporation, an evaporation region connected thereto having narrow flow cross-section for fast evaporation of the fluid, and a subsequent vapor chamber for pulsation damping and the controlled superheating of the vapor, the evaporation region being formed by a gap between concentrically nested cylindrical and/or conical tube sections and heat required for the evaporation and superheating processes is supplied by electric heating and/or by hot fluid and/or by catalytic or homogeneous combustion via the wall of the concentric tubes.

Compact total evaporator and device for carrying out the controlled drying, evaporation and/or reaction of a number of fluids
