Abstract: An evaporator with a cold storage function includes: a plurality of refrigerant tubes which have refrigerant flow paths and which are disposed in parallel with an interval therebetween; and a cold storage material container sandwiched and bonded between adjacent refrigerant tubes among a plurality of the refrigerant tubes and to be filled with a cold storage material, wherein the cold storage material container is formed by superimposing a pair of cold storage plates, each of which includes accommodating concavities to be filled with the cold storage material, and a plurality of convexities are formed with an interval therebetween in standing walls of the accommodating concavities of each of the cold storage plates.

Abstract: An evaporator with a cold storage function (10) includes: a plurality of refrigerant tubes (30) which have refrigerant flow paths (32, 33) and which are disposed in parallel with an interval therebetween; and a cold storage material container (40) sandwiched and bonded between adjacent refrigerant tubes (30, 30) among a plurality of the refrigerant tubes (30) and to be filled with a cold storage material (B), wherein the cold storage material container (40) is formed by superimposing a pair of cold storage plates (41, 41), each of which includes accommodating concavities (46, 47) to be filled with the cold storage material (B), and a plurality of convexities (46b, 47b) are formed with an interval therebetween in standing walls (46a, 47a) of the accommodating concavities (46, 47) of each of the cold storage plates (41).
