[0028] As Figure 4 The outer surface of the heat exchange tube bundle 18 is movably sleeved with a plurality of baffle plates 19, the number of the baffle plates 19 corresponds to the adjusting assembly 3, the baffle plate 19 includes a plate body 191, the two sides of the plate body 191 are embeddedly installed with a first magnet 192, and the outer surface of the plate body 191 is rotatably installed with a plurality of ball bearings 193.

[0029] The outer surface of the plate body 191 is rotatably installed with a plurality of ball bearings 193, so that when the plate body 191 slides in the inside of the shell 11, the abrasion of the inner wall of the shell 11 caused by friction is reduced.

[0030] As Figure 2 The inlet and outlet head 14 is divided into two cavities by the partition plate 15, the number of the heat exchange tube bundles 18 is a plurality, the plurality of heat exchange tube bundles 18 are divided into two groups, and one end of the two groups of heat exchange tube bundles 18 is respectively connected with the side edges of the two cavities in the inside of the inlet and outlet head 14.

[0031] Among them, the plurality of baffle plates 19 are divided into two groups, the two groups of baffle plates 19 are movably sleeved on the outer surfaces of the heat exchange tube bundles 18 of the upper and lower groups in a staggered manner, and the baffle plates 19 are movably sleeved in the inside of the shell 11.

[0032] By arranging the baffle plates 19, and arranging the baffle plates 19 on the outer surfaces of the heat exchange tube bundles 18 in a staggered manner on the upper and lower sides, the flow direction of the heat exchange fluid is changed, the contact time of the hot fluid and the heat exchange fluid is prolonged, and the heat transfer efficiency is improved.

Under the reaction force of the return spring 34, the toothed block 36 at one end of the locking block 35 is locked onto the side of the locking rack 114, preventing the sliding block 31 from sliding inside the limiting frame 112. This prevents the heat exchange fluid from interacting with the baffle 19 when flowing inside the shell 11, causing the baffle 19 to move inside the shell 11. The adjusting component 3 is locked and fixed inside the limiting frame 112, and the baffle 19 is fixed inside the shell 11 by the magnetic attraction of the first magnet 192 by the second magnet 37.

[0037] By using the magnetic attraction of the second magnet 37 to the first magnet 192, the second magnet 37 inside the sliding block 31 is moved by pushing the push block 32, thereby adjusting the movement of the first magnet 192 inside the housing 11, adjusting the position of the plate 191 inside the housing 11, thereby controlling the number of times the heat exchange fluid changes direction, controlling the contact time between the hot fluid and the heat exchange fluid, thereby adjusting the heat transfer effect of the hot fluid, and realizing the rapid adjustment of the temperature of the heat exchange fluid to adapt to engineering projects that require rapid temperature adjustment.

A rotating handwheel 22 is fixedly installed on the right side of the adjusting screw 23. Limiting rods 24 are fixedly installed at both ends inside the head cover 21. A moving block 25 is movably sleeved on the outer surface of the limiting rod 24. The moving block 25 is threaded onto the outer surface of the adjusting screw 23. An embedded block 26 is fixedly installed on the side of the moving block 25 near the tube sheet 110.

[0040] By using the shape of the embedded block 26, when the embedded block 26 is inserted into the inside of the heat exchange tube bundle 18 at one end, the flow area of the hot fluid is changed, thereby controlling the flow of the hot fluid, avoiding that the flow speed of the hot fluid is too fast, affecting the heat exchange effect, and increasing the power consumption of the heat exchanger.

[0041] The working process of the utility model is as follows:

[0042] In use, the hot fluid passes through the hot fluid inlet 16, passes through the inside of the upper end heat exchange tube bundle 18, reaches the inside of the adjusting head 2, and passes through the lower end heat exchange tube bundle 18, and flows out from the hot fluid outlet 17, at this time, the heat exchange fluid passes through the heat exchange fluid inlet pipe 12, changes the flow direction through the baffle 19, exchanges heat with the heat exchange tube bundle 18, and then flows out through the heat exchange fluid outlet pipe 13;

[0043] When it is needed to quickly reduce the temperature of the heat exchange fluid, the clamping blocks 35 on both sides of the shell 11 are pressed, the clamping blocks 35 descend in the inside of the push block 32, the fixing rod 33 is compressed, at this time, the clamping tooth blocks 36 are separated from the surface of the clamping rack 114, the push block 32 is pushed, the sliding block 31 slides in the inside of the limiting frame 112, under the magnetic attraction of the second magnet 37 to the first magnet 192, the plate body 191 moves to the side between the heat exchange fluid inlet pipe 12 and the heat exchange fluid outlet pipe 13, thereby reducing the number of the baffles 19, reducing the number of times of the flow direction of the heat exchange fluid, shortening the contact time of the hot fluid and the heat exchange fluid, and reducing the heat transfer efficiency, so as to achieve the purpose of reducing the temperature of the heat exchange fluid, and by the above-mentioned mode, the number of the baffles 19 between the heat exchange fluid inlet pipe 12 and the heat exchange fluid outlet pipe 13 is increased, the contact time of the hot fluid and the heat exchange fluid is prolonged, the heat transfer efficiency is improved, and the purpose of increasing the temperature of the heat exchange fluid is achieved;

[0044] In addition, by rotating the rotating hand wheel 22, the adjusting screw rod 23 is rotated, the moving block 25 moves to the side of the tube plate 110, the embedded block 26 is inserted into the inside of the heat exchange tube bundle 18, thereby controlling the flow area and the flow speed of the hot fluid in the inside of the heat exchange tube bundle 18, controlling the flow of the hot fluid according to the needs of the project, avoiding that the flow speed of the hot fluid is too fast, affecting the heat exchange effect, and increasing the power consumption of the heat exchanger.
