Abstract
A refrigerant evaporator includes a tank constituted by a tank portion and a header plate. The tank portion includes refrigerant collecting portions for guiding the refrigerant passed through a first path to the ends of the tank in the right-and-left direction and refrigerant distributing portions for guiding the refrigerant to the tubes forming a second pass. The header plate has refrigerant collecting/distributing space for the tubes. Side tanks are arranged to cover open portions at the ends of the tank in the right-and-left direction, and to spatially connect the flow passages. Separators are provided at portions where the flow passages are to be spatially blocked to constitute a front-and-rear right-and-left cross path. An increased sectional area of flow passages is obtained at the refrigerant flow corner portions relying upon a simple constitution, to decrease the pressure loss on the refrigerant side in the tank and to enhance performance.
