Heating and cooling cup holder

A cooling and heating cup holder comprising:

• an inner body having an open upper part to accommodate a drink container, the cylindrical inner body to surround the drink container, the inner body including a blower hole formed at a side surface thereof, into which air is introduced;
• a heat exchanger including a front surface covering the blower hole at an outside of the inner body and an inlet formed at a first side surface thereof and discharging the air introduced by the inlet into the inner body through the blower hole;
• heat exchanging pins provided in the heat exchanger, each heat exchanging pin being formed in a direction parallel to a direction of the air introduced by the inlet, the heat exchanging pins having different thicknesses;
• a thermoelectric element having a first surface being adhered to a rear surface of the heat exchanger;
• a heat radiator coupled to a second side of the thermoelectric element;
• an outer body surrounding a lower surface and a side surface of an outer side of the inner body to form a circulating space for circulating air between the inner body and the outer body;
• and
• a blower fan provided in the circulating space to transfer air in the circulating space to the inlet of the heat exchanger.
