Wherein the housing part is provided to seal the space in which the aluminum wheel is seated by being coupled with the base part under the control of the control part and the heating part is provided with a near infrared ray lamp or a near infrared ray heater to provide radiant heat to the aluminum wheel The present invention can be achieved by a vehicle aluminum heat treatment apparatus using near-infrared rays.

Here, the housing part may be provided in a hexahedron shape in which a lower surface is opened.

The heating unit may be disposed on at least one of the inner upper surface and the side surface of the housing unit.

Alternatively, the housing part may be provided in a hemispherical shape or a semi-elliptical shape in which a lower surface is opened.

Here, the heating unit may be disposed in the form of a circular coil along the inner surface of the housing unit.

On the other hand, the arrangement intervals of the heating units may be different.

Preferably, the heating unit may be disposed so as to be closer to the aluminum wheel disposed inside when the housing unit and the base unit are coupled.

According to the present invention, since the near-infrared rays in the closed space are used as the heat source to realize the wheel heating, the temperature of the wheel can be raised within a short time as compared with the conventional wheel heating method using the torch, and an eco- .
