1. A device for spraying a coolant, comprising:
one or more conduits providing a pathway;
a valve configured to regulate a flow of the coolant in the pathway;
a tube;
a heat transfer medium contained in the tube, wherein the heat transfer medium includes a plurality of voids configured to enable the coolant to pass therethrough;
a nozzle configured to receive the coolant from the pathway and to spray the coolant, the one or more conduits configured to form a continuous path with the valve and the tube to cause the coolant to be transferred to the nozzle;
a heater configured to generate a heat; and
a controller configured to control to open or close the valve and to control the heater to generate the heat,
the heater being disposed around an outer surface of the tube, and the tube being interposed between the heater and the heat transfer medium and configured to cause the heat generated by the heater to be inwardly transferred via the tube to the heat transfer medium, and
the heat transfer medium configured to transfer the heat transferred from the heater to the coolant passing through the plurality of voids included in the heat transfer medium.
