Abstract
A refrigerant evaporator includes a plurality of vertically disposed flat tubes, and a refrigerant distribution and supply section that causes inflowing refrigerant to flow out to the plurality of flat tubes on a downstream side. The refrigerant distribution and supply section includes a refrigerant supply section having plural supply spaces, a refrigerant introduction and distribution section having an introduction space to introduce the inflowing refrigerant from a lower end side surface, and a distribution space to distribute the refrigerant, and plural connecting passages that guide the refrigerant to the supply spaces. A first flat tube communicating with a lowermost-tier supply space positioned on the lowermost side is disposed at a height position included in a height range of the introduction space, and a lowermost-tier connecting passage that guides the refrigerant to the lowermost-tier supply space is disposed at a position higher than the introduction space.
