Description

(1) Technical field [0001] The invention relates to a heat-conducting oil heating reactor, in particular to a device and method for controlling the heating and cooling temperature of a heat-conducting oil reactor. (2) Background technology [0002] Heat conduction oil heating and cooling devices are widely used in industries such as reaction kettles, enamel kettles and circuit boards. In the original heating and cooling device, the direct switching between hot and cold oil causes a large temperature difference between the equipment, resulting in large temperature fluctuations and high temperatures (greater than 100°C) in the expansion tank A, which easily causes oil oxidation and wastes energy and power at the same time; when a cold oil tank is installed, The liquid level of the expansion tank A and the cold oil tank fluctuates greatly when switching between hot and cold, and the temperature of the cold oil tank is high and easy to oxidize; the large temperature diff...
