1. An evaporator configured to be used in a constant-temperature high-humidity storage chamber, comprising:
at least one cold-air temperature-humidity change unit located, of a first internal space and a second internal space defined by wall portions provided in an internal space of the constant-temperature high-humidity storage chamber, in the first internal space and including a plurality of crushed-ice heat exchangers each having an internal space into which crushed ice is fed; and
a blower device that circulates cold air between the first internal space and the second internal space, wherein
each of the plurality of crushed-ice heat exchangers has a side wall,
the plurality of crushed-ice heat exchangers are arranged in parallel in the first internal space such that at least parts of the side walls are opposed to one another with an equal gap in between along a direction of airflow by the blower device,
each of the plurality of crushed-ice heat exchangers has a cross section in a blade tubular shape, and
in a parallel line-up direction of the plurality of crushed-ice heat exchangers, a blade head portion and a blade tail portion of one crushed-ice heat exchanger respectively adjoin a blade tail portion and a blade head portion of another crushed-ice heat exchanger adjoining the one crushed-ice heat exchanger.
