Description

Technical Field

[0001] The utility model belongs to the technical field related to heat exchangers, and particularly relates to a tubular heat exchanger assembly capable of preventing damage due to water hammer effect. Background Art

[0002] The tubular heat exchanger assembly refers to a complete tubular heat exchanger unit assembled from multiple components. The tubular heat exchanger is a heat exchange device widely used in the industrial field. It realizes heat transfer through the heat exchange of two fluids inside and outside the tube. The main components of the tubular heat exchanger assembly include the shell, tube bundle, tube sheet, flange, seal and possible auxiliary components such as support structure, temperature measuring element and pressure gauge, but it still has the following disadvantages in actual use:

[0003] When the tubular heat exchanger is working, the oil is directly transported through it to cool the oil. However, during the oil transportation and cooling process, the cooling water flow path is directly increased through the partition. However, during the cooling process, the resistance of cooling water transportation is large and the transportation smoothness is not high enough.

[0004] When the tubular heat exchanger is working, the oil is directly transported into the heat exchanger. During long-term operation, the oil is fully transported. During the transportation, the pressure of the oil increases due to the start-up of the oil. At the same time, the fluctuation of the oil during transportation is large, which will cause a water hammer effect in the heat exchanger and cause safety hazards. Utility Model Content

By arranging a cooling shell, an infusion component, an infusion cavity and a movable plate, the utility model solves the problems that the resistance to cooling water transportation is large when the tubular heat exchanger is working, the transportation smoothness is not high enough, and the water hammer effect in the heat exchanger easily causes safety hazards.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a tubular heat exchanger assembly for preventing damage by water hammer effect, comprising a cooling shell, an infusion component, an infusion cavity and a movable plate, wherein the top and bottom ends of the cooling shell are both fixed with an infusion cavity, the two infusion cavities are symmetrically arranged, an infusion component is commonly fixed between the two infusion cavities, a movable plate is movably connected in the infusion cavity located below, a flexible block is fixed at the center of the bottom end of the movable plate, the infusion component comprises a spiral blade, the top and bottom ends of the spiral blade are respectively fixed at one end of the two infusion cavities close to each other, when working, cooling water is passed through the cooling shell, when the infusion component is working, oil is transferred and transported in the cooling shell, oil is transferred and transported through the infusion cavity, when the movable plate is working, the impact of oil transportation is removed, and the damage to the heat exchanger assembly caused by water hammer effect is reduced.

[0008] Furthermore, a water inlet pipe is fixedly connected to the upper part of the peripheral side of the cooling shell, and a drain pipe is fixedly connected to the lower part of the peripheral side of the cooling shell. The water inlet pipe and the drain pipe are parallel to each other. When the cooling shell is working, water is transported into it through the water inlet pipe, and after circulating in the cooling shell, it is discharged through the drain pipe.

[0009] Furthermore, the infusion assembly also includes a cooling tube, and the cooling tube is evenly and vertically fixed inside the spiral blade. The spiral blade is fixed on the inner wall of the cooling shell. When the infusion assembly is working, the oil passes through the cooling shell through the cooling tube to cool the oil.

[0010] Furthermore, fixing holes are evenly opened at one end of the infusion cavity close to the cooling shell, the cooling tube is fixed on the outside of the fixing holes at one end of the infusion cavity close to the cooling shell, and an oil delivery pipe is fixedly connected to the center of one end of the infusion cavity away from the cooling shell. When the infusion cavity is working, the oil is transported to the cooling tube through the fixed holes.

[0011] Furthermore, the top of the movable disk is fixedly connected to a reset spring, the top of the reset spring is fixed to a fixing frame, the fixing frame is fixed to the inner wall of the infusion cavity, and when the movable disk is working, the reset spring is used to reset the movable disk when the water hammer effect is removed.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problems of large resistance to cooling water transportation and insufficient transportation smoothness when the tubular heat exchanger is working by arranging a cooling shell, an infusion assembly and an infusion cavity. After the external heat dissipation device is working, the cooling water is transported to the cooling shell through the water inlet pipe, and then spirally transported to the drain pipe through the spiral blades. When working, the oil to be cooled is transported to the infusion cavity through the pipeline connected to the oil delivery pipe at the bottom end of the infusion cavity below, and then transferred through the infusion cavity below and transported to the cooling pipe through the fixed hole. After the cooling water passing between the spiral blades is cooled, the cooling pipe transports the oil to the infusion cavity above, and then passes through the infusion cavity above, and after being concentrated in the infusion cavity, it is discharged to the external pipeline through the oil delivery pipe at the top end of the infusion cavity above, completing the cooling of the oil, so that the resistance to cooling water transportation of the tubular heat exchanger is smaller when it is working, and the cold water transportation smoothness is higher.

[0015] The utility model solves the problem that the water hammer effect in the heat exchanger easily causes safety hazards by arranging the infusion chamber and the movable plate. When the oil is transported to the oil delivery chamber from the oil delivery pipe at the bottom end of the oil delivery chamber, the oil first rushes to the flexible block to offset part of the impact of the oil, and then is dispersed to the opening on the movable plate through the flexible block.
