In this way, the heat sink 310 can be quickly and efficiently dissipated by the defrosted water 12.

In a specific implementation, when the amount of the defrosting water 12 collected in the S-shaped communicating vessel is large, the excessive defrosting water 12 may be guided into the water receiving tray 340.

In a specific implementation, the third section 325 of the S-shaped communicator is connected to the second section 324 thereof and is adapted to guide the surplus defrost water 12 in the S-shaped communicator to the drain pan 340.
