1. An ion exchanger, comprising:
a housing that includes an inlet port, into which a coolant flows, and an outlet port, through which the coolant flows out, wherein the housing extends in a vertical direction;
a tube member that is arranged inside the housing so that a center axis of the tube member extends in the vertical direction; and
an ion exchange resin that is arranged between an outer surface of the tube member and an inner surface of the housing, wherein
the ion exchanger is configured such that
some of the coolant that has flowed into the housing through the inlet port flows directly to the outlet port, and
some of the coolant that has flowed into the housing through the inlet port flows to the outlet port after passing through the ion exchange resin and the tube member, wherein
a first flow passage and a second flow passage are formed in the housing,
the first flow passage is configured to cause the coolant that has flowed in through the inlet port to flow directly to the outlet port,
the second flow passage is configured to cause the coolant that has flowed in through the inlet port and passed through the ion exchange resin to flow to the outlet port, and
the first flow passage and the second flow passage are formed to join together in a state of being oriented in a same direction toward the outlet port, wherein
the inlet port and the outlet port are located at a lower end of the housing,
the ion exchanger further comprises a separator that is provided beneath the tube member in the vertical direction, wherein a region of the housing that is beneath the tube member in the vertical direction defines a lower end portion in the housing,
the separator includes:
a bottom wall that divides the lower end portion in the housing vertically; and
a tubular wall that connects a section below the bottom wall to a lower end of the tube member, and
the separator defines a section above the bottom wall as the first flow passage, and defines the section below the bottom wall as the second flow passage.
