PURPOSE: A method for winding a copper pipe on the aluminum inner case of a Kimchi refrigerator to increase refrigeration efficiency is provided by increasing the contact surface of the copper pipe and the cask. CONSTITUTION: A method for winding a copper pipe on the aluminum inner case of a Kimchi refrigerator is characterized in transforming a circular copper pipe into half circle, ellipse, or rectangular forms as the form of press rollers(3) while placing the cooper pipe between a contact roller(4) and an inner case(1), and winding the cooper pipe by rotating an inner case. The starting part and ending part of the cooper pipe have an original circular form, and the contact part of the pipe is transformed to increase the contact surface.
