a receiving pan configured to receive water generated by dew condensation in the first heat exchanger; and
a water supply member configured to supply the water in the receiving pan to the evaporator,
the evaporator includes:
a water storage pan configured to receive the water from the receiving pan; and
a plurality of capillaries configured to pump up water in the water storage pan by capillary action, each of the plurality of capillaries having a plurality of pores in a circumferential surface of the respective capillaries.

2. The information processing device according to claim 1 , wherein the one or more information processing device main bodies include a heat generating component configured to generate heat based on an operation.

3. The information processing device according to claim 1 , wherein cooling water at an environmental temperature or lower is supplied from a cooling water supply device to the first heat exchanger.

4. The information processing device according to claim 1 , wherein the water from the water supply member evaporates in the evaporator when the discharged air passes through the evaporator.

5. The information processing device according to claim 1 , wherein the water supply member includes: a water storage pan provided below the evaporator: and a flow channel configured to couple the receiving pan and the water storage pan.

6. The information processing device according to claim 5 , wherein each of the plurality of capillaries includes one end which is immersed in the water of the water storage pan and the other end in which the water is evaporated from the pores when the discharged air passes in the evaporator.

7. The information processing device according to claim 1 , further comprising:
a second heat exchanger provided between the first heat exchanger and the one or more information processing device main bodies,
wherein a refrigerant that passes through the first heat exchanger is supplied to the second heat exchanger.

8. The information processing device according to claim 7 , wherein the air blower and the second heat exchanger are provided in the one or more information processing device main bodies.

9. The information processing device according to claim 1 , further comprising:
a second heat exchanger provided between the first heat exchanger and the one or more information processing device main bodies;
a third heat exchanger provided between the one or more information processing device main bodies and the evaporator; and
a pipeline configured to supply a portion of a first refrigerant from the first heat exchanger to the third heat exchanger, join a remaining portion of the first refrigerant from the first heat exchanger and a second refrigerant from the third heat exchanger together, and supply a joined refrigerant to the second heat exchanger.

10. The information processing device according to claim 1 , wherein the first heat exchanger and the evaporator are provided for each of the one or more information processing device main bodies.
