[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used.

[0003] In order to increase the thermal insulation effect of the outer shell of the existing heat exchanger, a vacuum chamber is set in the shell, which is evacuated to a vacuum state by a vacuum pump and then closed by a sealing valve.

[0021] A fixing ring 7 is integrally formed at the right end of the sealing tube 6, and a fixing plate 8 is integrally formed on the inner wall of the sealing tube 6. A sliding hole 9 is provided in the middle of the fixing plate 8, and a sliding rod 10 is slidably installed on the inner wall of the sliding hole 9. A baffle 11 is fixedly installed on the right end of the sliding rod 10. A spring 12 is sleeved on the side wall of the sliding rod 10, and the left end of the spring 12 is fixedly installed on the right side of the fixing plate 8. The right end of the spring 12 is fixedly installed on the left side of the baffle 11, and the right side of the baffle 11 is tightly fitted on the left side of the fixing ring 7;

[0022] The baffle 11 includes a plate body 13 , which is connected to the slide rod 10 . A rubber ring 14 is fixedly mounted on the right side of the plate body 13 . An annular groove 15 is provided on the left side of the fixing ring 7 . The rubber ring 14 fits tightly in the annular groove 15 .

[0023] Figure 3 The spring 12 shown is in a slightly compressed state, and the rubber ring 14 is pressed tightly into the annular groove 15 by the compression elasticity of the spring 12 .

[0024] Specifically, a convex surface 16 is provided on the right side of the rubber ring 14 , and an inner right wall of the annular groove 15 is provided with a shape matching the convex surface 16 , and the convex surface 16 is tightly fitted on the inner right wall of the annular groove 15 .

[0025] The provision of the circular convex surface 16 can increase the sealing area with the annular groove 15, thereby improving the sealing effect.

[0026] Specifically, a ring portion 17 is integrally formed on the outer wall of the rubber ring 14 , and the right side surface of the ring portion 17 is tightly fitted on the left side surface of the fixing ring 7 .

[0027] The provision of the ring portion 17 can further enhance the sealing effect of the rubber ring 14 on the fixing ring 7 .

[0028] Specifically, the fixing plate 8 is a perforated plate.

[0029] Specifically, it also includes a sealing plate 18, an internal thread ring 19 is integrally formed at the outer edge of the right side surface of the sealing plate 18, a sealing ring 20 is fixedly installed on the left side surface of the sealing tube 6, and a thread matching the internal thread ring 19 is provided on the left side of the outer wall of the sealing tube 6. The internal thread ring 19 is screwed to the left side of the outer wall of the sealing tube 6, and the right side surface of the sealing plate 18 is tightly fitted to the left side surface of the sealing ring 20.

[0031] Specifically, the heat exchange tube bundle 4 is a pure copper tube.

[0032] Pure copper has excellent thermal conductivity and can increase the heat exchange efficiency of the medium in the heat exchange tube bundle 4 .

[0033] Working principle: When the vacuum chamber 5 is evacuated, the sealing plate 18 can be removed and connected to the sealing tube through an external vacuum pump. The strong suction force generated by the vacuum pump causes the baffle 11 to move to the left, and the inside of the vacuum chamber 5 is evacuated to a vacuum state until the sealing tube 6 is also evacuated to a vacuum state. Then the vacuum pump is turned off, and the baffle 11 is sealed on the fixing ring 7 through the rebound effect of the spring 12. This vacuuming method can effectively prevent external air from leaking into the vacuum chamber 5 after the vacuuming is completed, thereby ensuring the thermal insulation effect of the heat exchanger shell 1;

[0034] The upper medium pipe 3 injects extremely high temperature heat transfer medium into the heat exchange tube bundle 4, and cold water is passed into the left tube body 2. The cold water enters the heat exchanger shell 1 and contacts the heat exchange tube bundle 4 for heat exchange, and is discharged from the right tube body 2.
