## Abstract

A heating and cooling cup holder for vehicles includes a heat insulating cup where a container accommodating part is formed with an upper part opened so that a beverage container can be accommodated, a heat exchange cup installed in the container accommodating part formed in the heat insulating cup, a circulation duct installed so that an air suction port and an air exhaust port are formed in the heat exchange cup, a circulation fan circulates and introduces air into the heat exchange cup through the air suction port and the air exhaust port formed in the circulation duct, a radiation plate heat-exchanging the air introduced into the heat exchange cup by the circulation fan to re-supply to the heat exchange cup through the circulation duct, and a thermoelectric element installed so that the radiation plate can absorb and generate heat.

## Claims

### Claim 1

A heating and cooling cup holder for vehicles comprising:
a heat insulating cup where a container accommodating part is formed with an upper part opened so that a beverage container can be accommodated,
a heat exchange cup installed in the container accommodating part formed in the heat insulating cup,
a circulation duct installed so that an air suction port and an air exhaust port are formed in the heat exchange cup,
a circulation fan that circulates air while introducing air into the heat exchange cup through the air suction port and the air exhaust port formed in the circulation duct, wherein the circulation fan is installed on one side of the heat exchange cup where the air suction port of the circulation duct is located,
a radiation plate heat-exchanging the air introduced into the heat exchange cup by the circulation fan to re-supply to the heat exchange cup through the circulation duct, and
a thermoelectric element installed so that the radiation plate can absorb and generate heat;
wherein a radiation fan for discharging heat to the outside is installed at the radiation plate where the thermoelectric element is installed, on the side of the radiation plate perpendicularly in a plane view to the side of the heat exchange cup on which the circulation fan is installed,
wherein the radiation plate is installed in the heat insulating cup with the radiation fan in a state where it is fixedly coupled to a radiation duct, and
wherein a heat exchange fin that is bent as an L-shape in the plane view to form a plurality of flow paths is installed inside the radiation plate.

### Claim 2 (depends on 1)

A heating and cooling cup holder for vehicle according to claim 1, further comprising a cover installed on the upper part of the heat insulating cup where the heat exchange cup is installed.
