1. An induction heating device comprising:
a casing;
a first induction heater located within the casing;
a first heat sink located vertically below the first induction heater and configured to dissipate heat from the first induction heater;
a first heat pipe that passes through the first heat sink, that extends outward from the first induction heater, and that is configured to discharge heat from the first heat sink out of the first induction heater;
an air-discharge fan located at an inner side of the casing and configured to discharge air from inside of the casing to outside of the casing;
a cooling fan located at the inner side of the casing and configured to blow air to the air-discharge fan, the cooling fan being spaced apart from the air-discharge fan at the inner side; and
a blowing-guide that includes a plurality of plates and that is located between the air-discharge fan and the cooling fan,
wherein the first heat pipe passes through side surfaces of the plurality of plates of the blowing-guide,
wherein the first heat pipe has an end that protrudes from the first induction heater to the blowing-guide in a first direction such that the protruded end of the first heat pipe is located between the cooling fan and the air-discharge fan, and
wherein the plurality of plates are spaced from each other in the first direction to thereby define a plurality of air-flow paths extending along the blowing-guide from the cooling fan to the air-discharge fan in a second direction that is orthogonal to the first direction.
