The valve controls the heat medium to bypass the radiator (5, 6) when the temperature of the heat medium is lower than a first predetermined value. The valve controls the heat medium to flow through the radiator (5, 6) when the temperature of the heat medium is higher than or equal to the first predetermined value.

The present invention relates to an exothermic container to be used in a microwave oven which cooks foods using a magnetron. The exothermic container absorbs a portion of the microwaves generated by the magnetron and generates heat to cook foods in the cooking chamber of the microwave oven. The exothermic container to be used in the microwave oven is produced by the steps of providing an exothermic enamel glaze, coating a metal container to be produced into an enameled container (low carbon steel plate, aluminum, and stainless steel to be produced into an enameled container) with the exothermic enamel glaze provided in the previous step, drying the resulting structure, firing the resulting structure to vitrify same, and cooling the resulting structure, to thereby achieve improved resistance against hot temperatures, improved exothermic performance,; and higher quality as compared to conventional exothermic container products (silicon rubber and ferrite).
