[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. It plays an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers. The wound tube heat exchanger is one of the common heat exchangers because of its compact structure and large heat transfer per unit area.

[0003] In the process of using the existing heat exchanger, due to the uneven winding of the pipes, some parts of the pipes are stuck together, which can easily affect the heat exchange.

[0025] The heat dissipation pipe 6 is arranged inside the cylinder 1, and the heat dissipation pipe 6 comprises a plug 601, a connecting column 602, a tube body 603 and a gasket 604. The connecting column 602 is arranged in the middle of the plug 601, and the gasket 604 is arranged on the outside of the connecting column 602, and the tube body 603 is wound around the outside of the gasket 604;

[0026] The airbag 7 is arranged inside the connecting column 602, and the outer end of the airbag 7 is connected to the valve plate 8, the outer side of the valve plate 8 is connected to the valve column 10, and the outside of the valve column 10 is provided with a spring 9, the top of the valve column 10 is provided with a bracket 11, and the bracket 11 is fixedly connected to the plug 601.

[0027] like Figure 1 , Figure 2 and Figure 4The middle plug 601 is symmetrically arranged at the two ends of the connecting column 602, and the upper and lower plugs 601 are respectively connected to the heat medium inlet 2 and the heat medium outlet 3, and holes are evenly opened on the outside of the connecting column 602 to balance the pressure difference between the internal and external fluids. Several groups of gaskets 604 are arranged on the plugs 601, and the outside of each group of gaskets 604 is wrapped with a tube body 603 to evenly separate the tube bodies 603, so that the tube bodies 603 are evenly heated. The outside of the gasket 604 is evenly spaced with grooves, and the tube bodies 603 are wrapped in their grooves to facilitate the separation of the tube bodies 603.

[0028] like Figure 2 and Figure 3 Valve plates 8 are symmetrically arranged at the upper and lower ends of the middle airbag 7, and the valve plate 8 is slidingly and sealingly connected to the connecting column 602 to avoid mixing of internal and external fluids.

[0029] Working principle: When using the spiral wound tube heat exchanger with high heat transfer efficiency, Figure 1 As shown, a heat medium fluid is introduced into the cylinder 1 through the heat medium inlet 2, so that the heat medium fluid flows out from the heat medium outlet 3 through the heat dissipation pipe 6. While the heat medium fluid is introduced, a refrigerant fluid is introduced into the cylinder 1 through the refrigerant inlet 4, and the refrigerant fluid cools the heat medium fluid in the heat dissipation pipe 6, and then the refrigerant fluid flows out from the refrigerant outlet 5;

[0030] When the refrigerant fluid cools the heat medium fluid, Figure 2 As shown, the tube body 603 is evenly separated by the gasket 604, so that the tube body 603 can be fully in contact with the refrigerant fluid, which is convenient for heat dissipation. When the pressure of the refrigerant fluid is greater than that of the heat medium fluid, as shown in FIG. Figure 3 As shown, the airbag 7 is squeezed, so that the airbag 7 stretches to squeeze the valve plate 8, so that the valve plate 8 squeezes the spring 9 and slides through the valve column 10, thereby adjusting the pressure difference between the refrigerant fluid and the heat medium fluid. On the contrary, when the pressure of the heat medium fluid is greater than that of the refrigerant fluid, the valve plate 8 squeezes the airbag 7, so that the airbag 7 contracts, and the pressure difference between the refrigerant fluid and the heat medium fluid is balanced. When the pressure difference is large, the pressure can also be relieved through the pressure relief valve 12, thereby protecting the heat exchanger. This is the entire working process of the wound tube heat exchanger with high heat exchange efficiency.
