Embodiment 1
[0021] Such as figure 1 and 2 As shown, in the present invention, firstly, the split-pass partition of the tube bundle is arranged obliquely, which can reduce the impact force of the cooling medium on the split-pass partition when the cooling medium flows through, and the inclination angle of the split-pass partition is set at 15-35° ° range, the impact force of the cooling medium is reduced to the minimum, and the T-shaped rib installed at the bottom of the split-pass partition can enhance its stability and impact resistance; the groove on the split-pass partition can act as a guide The role of the flow can make the cooling medium quickly pass through the tube bundle, and conduct heat exchange treatment with the medium flowing into the second liquid inlet pipe. The depth of the groove is 5-12mm, so that the flow rate of the cooling medium can reach the best; Heat transfer tube 1, fixed tube plate 2 and floating head tube plate 3, one end of heat transfer tube 1 is arranged o...

The invention discloses an application method for a heat exchanger tube bundle. The method comprises the steps that due to the tube bundle, a pass partition plate is arranged in an inclined mode, whena cooling medium flows through the tube bundle, the impact force caused by the cooling medium to the pass partition plate can be lowered, the inclined angle of the pass partition plate is 15-35 degrees, the impact force of the cooling medium is lowered to the minimum, and due to T-shaped reinforcing ribs installed at the bottom of the pass partition plate, the stability and impact resistance canbe enhanced; a groove in the pass partition plate can achieve the flow guiding effect, the cooling medium can pass through the tube bundle rapidly, heat exchange treatment is performed on the coolingmedium and a medium flowing through a second liquid inlet tube flow, the depth of the groove is 5-12 mm, and the flow speed of the cooling medium reaches the best speed.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to an application method of a heat exchanger tube bundle. Background technique [0002] According to the structural classification of the heat exchanger, it can be divided into: floating head heat exchanger, fixed tube-sheet heat exchanger, U-shaped tube-sheet heat exchanger, plate heat exchanger, etc. Due to the connection between the tube bundle and the shell in the fixed tube-sheet heat exchanger, U-shaped tube-sheet heat exchanger, and plate heat exchanger, the tube bundle is heated and expanded during heat exchange, and when the temperature difference between the two media is large, the tube bundle and the shell There will be temperature difference stress between the bodies, which will lead to damage to the tube bundle. Contents of the invention [0003] The invention provides an application method of a heat exchanger tube bundle to prolong the service life of the tube bundle. [0004] T...
