Description

Technical Field

[0001] The utility model relates to the technical field of coil structures, in particular to a coil structure for preventing freezing and cracking. Background Art

[0002] As we all know, coils are a commonly used heat exchange device, usually made of metal, with a spiral or winding shape. Its main function is to transfer heat. It is widely used in industry and construction. There is a medium inside the coil, such as water, steam, air, etc., flowing in it, and heat is transferred through contact with the external environment. In the heating system, the coil can circulate hot water or steam through it, releasing heat to the indoor air to play a role in heating; while in the air-conditioning system, the coil can circulate refrigerant, absorb indoor heat and discharge it, playing a role in cooling. Coils have the advantages of simple structure, high thermal efficiency, and easy installation, so they are widely used in various heat exchange systems.

[0003] However, in traditional coil structures, when the temperature of the medium inside the coil drops sharply, especially in cold environments, the water in the medium may freeze quickly, causing the coil material to be under tremendous pressure and crack. Especially at the bends of the coil, due to uneven force, stress concentration will occur, and the ability to resist freezing cracking is poor. Therefore, technical improvements are urgently needed.

When the coil structure is in use, the temperature inside the shell is conveniently monitored in real time by a temperature monitor. When the set temperature threshold is reached, the bending part of the upper copper tube can be heated by starting the heating rod. At this time, the servo motor is started to drive the rotating rod to rotate and the wind wheel to rotate at the same time, thereby diffusing the internal temperature, thereby avoiding local low temperature and reducing the risk of freezing and cracking of the coil.

The outer shell is made of galvanized steel plate material with good corrosion resistance. The guardrail at the front end of the inner wall of the outer shell can protect the internal components from external interference, and the practical performance is high.
