It is particularly suitable for applications requiring stable and precise heating, such as semiconductor manufacturing, pharmaceutical production, and precision experiments.
[0003] Existing publication number CN106288323A discloses a high-efficiency water circulation heating system, including a hot water tank, a cold water tank, and a heating element. The hot water tank and cold water tank are spaced apart. The left end of the heating element is connected to the hot water tank, and the right end is connected to the cold water tank. The hot water tank, cold water tank, and heating element are interconnected. The heating element is inclined, and the horizontal plane at the left end of the heating element is higher than the horizontal plane at the right end. This high-efficiency water circulation heating system can achieve water circulation heating, ensuring that the hot water (higher temperature) is always in the hot water tank and the cold water (lower temperature) is always in the cold water tank. This not only ensures a stable water temperature in the hot water tank but also has high heating efficiency and low energy consumption, meeting the requirements of energy conservation and emission reduction. The inventors discovered the following problems with the existing technology during the development of this utility model:
