Embodiment 1
[0026] Example 1 Spiral wound tube heat exchanger
[0027] Figure 1 shows the structure of a preferred embodiment of a spiral wound tube heat exchanger of the present invention, which is used for water cooling of fluids such as lubricating oil.
[0028] Such as Picture 1-1 As shown, the spirally wound tube heat exchanger includes a shell 1 and a spiral tube bundle with two ends of the shell installed on the tube sheet 6. The two ends of the shell 1 are provided with a tube pass inlet 1-1 and a tube pass outlet 1. -2. On the side wall of the shell 1, there are shell side inlets 1-3 and shell side outlets 1-4. The two ends of the spiral tube bundle composed of multiple spiral tubes 2 are installed on the tube plates 6 at both ends of the heat exchanger.
[0029] Structural combination of spiral tube bundle Picture 1-1 with Figure 1-4 As shown, the spiral tube bundle is composed of 6 layers of spiral tubes 2 concentrically wound into a spiral shape, and each layer of spiral tubes 2 use...
Embodiment 2
[0047] Example 2 Variable flow spiral tube reverse winding type cooling device
[0048] Such as figure 2 Shown is a variable-flow spiral tube reverse-wound cooling device, and the spiral tube heat exchanger adopts the structure of Embodiment 1.
[0049] The cooling device includes a spiral tube heat exchanger, a temperature sensor, a control system, a variable frequency motor, and a pump driven by the variable frequency motor. The temperature sensor is arranged on the tube side outlet pipeline of the spiral wound tube heat exchanger. The output end is connected with the input end of the control system, the input end of the variable frequency motor is connected with the output end of the control system, and the outlet of the pump is connected with the shell side inlet of the spiral wound tube heat exchanger.
[0050] The temperature at the outlet of the winding tube heat exchanger is measured by a temperature sensor. The temperature sensor measures the temperature and uploads it to ...
