Abstract (en)
[origin: EP2336702A1] A refrigerant evaporator (1), in which one of a plurality of blocks is a U-turn block portion (15), includes a plurality of refrigerant-distribution holes (4M, 5M), which communicate between first tank portions (6, 8) and second tank portions (7, 9), provided in the U-turn block portion (15) and in partition walls (4C, 5C) therein that partition the first tank portions (6, 8) and the second tank portions (7, 9) of top and bottom tanks (4, 5). For the refrigerant-distribution holes (4M, 5M), assuming the distance between the plurality of holes as b, the hole length in the hole-row direction as a, and the thickness of the partition wall as t, a/b is set to a/b ‰¤ - 0.0697 × t 2 + 0.3274 × t + 0.4594, where t = 1 to 2 mm.
