Evaporator with cool storage function

摘要

An evaporator with a cool storage function includes a plurality of refrigerant flow tubes, fins, and cool storage material containers. Each of the cool storage material containers has a longitudinal direction and includes a third side wall and a fourth side wall opposite to the third side wall. The third side wall and the fourth side wall have first convex portions and second convex portions, respectively. The cool storage material containers are provided in a second part of spaces such that the first convex portions contact a first side wall of one of the plurality of refrigerant flow tubes and the second convex portions contact a second side wall of another of the plurality of refrigerant flow tubes. The third side wall and the fourth side wall have a concavo-convex shape in a cross-section perpendicular to the longitudinal direction.

1. An evaporator with a cool storage function, comprising:
a first header tank which longitudinally extends to define a width direction of the evaporator; a second header tank which extends along the width direction; a plurality of refrigerant flow tubes each having a first end and a second end opposite to the first end in a longitudinal direction of the plurality of refrigerant flow tubes, said each first end being connected to the first header tank, said each second end being connected to the second header tank, the plurality of refrigerant flow tubes comprising:
a first flow tube having a first outer side wall and a second outer side wall opposite to the first outer side wall in the width direction;a second flow tube opposed to the first flow tube in the width direction and having a third outer side wall and a fourth outer side wall opposite to the third outer side wall in the width direction, the third outer side wall facing the second outer side wall to form a fin space between the first flow tube and the second flow tube; anda third flow tube opposed to the second flow tube in the width direction and having a fifth outer side wall and a sixth outer side wall opposite to the fifth outer side wall in the width direction, the fifth outer side wall facing the fourth outer side wall to form a first container space between the second flow tube and the third flow tube; a fin provided in the fin space between the first flow tube and the second flow tube to directly contact the second outer side wall of the first flow tube and the third outer side wall of the second flow tube; and a cool storage material container containing a cool storage material, the cool storage material container including a storage first outer side wall and a storage second outer side wall opposite to the storage first outer side wall in the width direction, the storage first outer side wall having first convex portions on the storage first outer side wall, the storage second outer side wall having second convex portions on the storage second outer side wall, the cool storage material container being provided in the first container space between the second flow tube and the third flow tube such that the first convex portions directly contact the fourth outer side wall of the second flow tube and the second convex portions directly contact the fifth outer side wall of the third flow tube.
