The present invention discloses a cooler (3, 4) cools electric parts of a vehicle using heat medium. A radiator (5, 6) emits heat of the heat medium to air, and a valve (21, 22, 31, 35, 36, 37) changes a flow of the heat medium based on a temperature of the heat medium. 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.

An electronic part mounting heat-dissipating substrate which includes: a conductor plate which is formed on lead frames of wiring pattern shapes; and an insulating member which is provided between the lead frames of the wiring pattern shapes on the conductor plate; wherein a plate surface of a part arrangement surface of the conductor plate and a top surface of the insulating member at a side of the part arrangement surface form one continuous surface, wherein a plate surface of a back surface of the part arrangement surface of the conductor plate and a top surface of the insulating member at a side of the back surface at the part arrangement surface-side are formed in an identical plane, wherein the substrate is formed in a circular shape.

The invention relates to a heating container used in a microwave oven using a magnetron to cook food. The heating container absorbs a part of the high-frequency wave generated by the magnetron and generates heat, and uses the high-frequency wave to cook the food in the cooking room of the microwave oven. In the present invention, the exothermic enamel glaze is produced, and the above-mentioned manufactured exothermic enamel glaze is coated on a container made of metal material for enamel (steel plate for low-carbon enamel, aluminum, stainless steel), dried, and then vitrified and fired. , cooling, and produce a heating enamel container for microwave ovens. Therefore, compared with existing heating container products (silicone rubber + ferrite), it can withstand high temperatures, has higher heating performance, and can achieve high-grade. The method for manufacturing the heat-generating enamel glaze is characterized in that, in the glaze (vitreous Frit) commonly used in enamel treatment, ferrites with high magnetic permeability (MnZn class, MgCuZn class, NiZn class, etc.) are added separately or mixed. type) and metal soft magnetic material (Fe-Si type, Fe-Si-Al type, Fe-Si-B type, Fe-Si-B-Co type, Fe-Ni type) alloy powder to produce A heat-generating enamel glaze that absorbs microwaves (2.45GHz) in a microwave oven and converts them into heat energy.
