Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a volumetric floating coil heat exchanger. Background Art

[0002] The volumetric floating coil heat exchanger is a common heat exchange equipment, which is mainly composed of a closed container (tank) and an internal floating coil. This type of heat exchanger is usually used in industrial and commercial hot water supply systems, such as chemical, oil refining, shipbuilding and other fields, as well as high-end hotels, restaurants, office buildings, school research buildings, heating, air conditioning, hot water supply systems in boiler rooms, heat exchange station rooms, air conditioning rooms, etc.

Although a certain amount of pressure can be offset by passive recovery of water vapor, when the temperature is high for a long time, the passive water vapor reflux speed is limited by space and leads to insufficient speed, resulting in excessive pressure. In addition, during the installation of the floating coil, since the pipe body of the floating coil is immersed in water, the force on the upper and lower ends is small, and the downward gravity received in daily use is large, and it is difficult to remove and repair.

When it is needed, the generated water vapor is discharged into the steam cooling box 223 along the exhaust pipe 222 along the steam collecting port 221. At this time, the cold air generated by the condenser 224 will condense the hot air in the steam cooling box 223, so that the water vapor is cooled and turned into water droplets, which are then discharged from the condensate drain port 225.

[0032] Embodiment 2

[0033] See also Figure 1 and Figure 4 As shown, compared with Example 1, as another implementation of the utility model, a support assembly 3 is installed on the lower side of the heat exchange cylinder 1, and the support assembly 3 includes a welding ring 31 and a support leg 32. The welding ring 31 is welded on the lower side of the heat exchange cylinder 1, and the lower side of the welding ring 31 is welded with a support leg 32.

[0034] Working principle: A volumetric floating coil heat exchanger is moved to the working position. When in use, the first step is to place the heat exchange cylinder 1 welded with the welding ring 31 and the supporting foot 32 to the position where it needs to be used. The second step is to penetrate the supporting suspension rod 246 into the floating coil 243, and then screw the tray 247 to the end of the supporting suspension rod 246. Then, lift the connected supporting rod 242 to prevent it from entering the heat exchange cylinder 1, and then insert the two ends into the fixing groove 241. After fixing, fix the heating water inlet 244 and the heating water outlet 245 to the upper and lower ends of the floating coil 243 respectively. After fixing, the third step is to install the top cover 213 with the sealing flange 212, and clamp the sealing rubber ring 211 in the middle of the heat exchange cylinder 1. After fixing, connect the external water pipe to the inlet The water inlet 232 of the water inlet 231 is connected to supply water to the heat exchange cylinder 1. As the floating coil 243 is heated, the heat exchange cylinder 1 absorbs heat and begins to evaporate water vapor. The water vapor is poured into the steam cooling box 223 through the steam collecting port 221 and the exhaust pipe 222. The condenser 224 cools the water vapor, and the cooled water is discharged from the condensate drain port 225. Finally, when the air pressure is too high, the air pressure sensor 235 at the top of the air pressure chamber 233 and the sealing cover 234 will sense that the air pressure exceeds the critical value. At this time, the support plate 236 between the air pressure chamber 233 and the sealing cover 234 will be lifted by the co-positioned hydraulic rod 237, thereby discharging excess water vapor, thus completing the use process of a volumetric floating coil heat exchanger.
