[0002] As one of the important components in the heat exchanger unit, the heat exchanger is used by the high-temperature flow medium to enter the heat exchanger from the primary side inlet of the heat exchanger unit for heat exchange and then flow out from the primary side outlet of the unit. The heat exchangers used in existing heat exchangers are mostly plate type.

[0003] A search revealed patent application number 202211338522.3, which discloses a heat exchanger for a heat exchange unit. The patent includes a fixed plate, a heat exchange fin assembly, and two control components.

However, existing plate heat exchangers have the following problems in actual use:

[0005] Secondly, during installation and commissioning, it is not convenient to flexibly adjust the installation angle of the entire heat exchanger, thereby failing to meet the complex piping connection requirements of the heat exchanger unit, resulting in low assembly efficiency.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1, with reference to Figure 1-3 , a heat exchanger for a heat exchange unit, comprising a heat exchange unit connecting frame 1, a support platform 2, a fixed pressing plate 3 fixedly connected to the top outer wall of the support platform 2, and a movable pressing mechanism;

[0027] In this embodiment, the heat exchanger unit connecting frame 1 is subsequently fixed to a designated position of the heat exchanger unit by bolts. Four guide rods 4 are welded to the side wall of the fixed pressure plate 3. Heat exchanger plates 5 are equidistantly arranged between the four guide rods 4.

[0028] In this embodiment, the movable pressing mechanism includes a slide 6 provided on the top of the support platform 2, a transverse screw 7 rotatably mounted in the slide 6, an adjustment block 8 threadedly connected to the transverse screw 7, and a locking pressure plate 10 fixedly connected to the top outer wall of the adjustment block 8;

[0029] Furthermore, the outer wall of the adjusting block 8 is slidably connected to the inner wall of the slide groove 6, which can ensure the stability of the linear motion of the locking pressure plate 10. The outer wall of one end of the transverse screw 7 is fixedly connected to the first handwheel 9. Four guide holes 11 are opened on one side of the locking pressure plate 10, and the four guide holes 11 are respectively adapted to the four guide rods 4;

[0030] This embodiment can be used as a reference when assembling Figure 1 : The required number of heat exchanger plates 5 are stacked together along the four guide rods 4 in sequence. After the stacking is completed, the horizontal screw 7 is driven to rotate by operating the No. 1 hand wheel 9. Then, under the limit of the slide 6, the adjustment block 8 threadedly connected to the horizontal screw 7 will drive the locking plate 10 forward until it cannot move. At this time, all the stacked heat exchanger plates 5 can be pressed and fixed. Figure 3 As shown, this completes the entire assembly work.

[0031] Example 2, reference Figure 1-2 and Figure 4 This embodiment is optimized based on the first embodiment, specifically: a heat exchanger for a heat exchange unit, further comprising an angle adjustment mechanism, the angle adjustment mechanism comprising:

[0032] Angle adjustment shaft 12, which is connected to the top center inner wall of the heat exchange unit connecting frame 1 through a bearing, and the top end of the angle adjustment shaft 12 is welded to the bottom outer wall of the support platform 2;

[0033] The worm gear 13 and the support base 14 are fixedly mounted on the bottom end of the angle adjustment shaft 12, and the support base 14 is fixedly connected to the top inner wall of the heat exchange unit connecting frame 1;

[0034] The control assembly includes a control shaft 15 rotatably mounted on the support 14, a worm 16 fixedly mounted on the control shaft 15 and meshing with the worm gear 13, and a second handwheel 17 fixedly connected to the outer wall of the front end of the control shaft 15;

[0035] Furthermore, a cold medium inlet and a hot medium inlet are sequentially provided on the upper portion of one side of the fixed pressing plate 3, and a cold medium outflow outlet and a hot medium outflow outlet are sequentially provided on the lower portion of one side of the fixed pressing plate 3;

[0036] During the specific implementation of this embodiment: the worm 16 on the control shaft 15 is driven to rotate by the second handwheel 17, and then the worm wheel 13 engaged with the worm 16 drives the angle adjustment shaft 12 to rotate. Moreover, since the engagement between the worm 16 and the worm wheel 13 is self-locking, the installation angle of the entire heat exchanger can be flexibly adjusted, thereby better meeting the complex piping connection requirements of the heat exchanger unit during installation and commissioning, thereby helping to improve the assembly efficiency of the heat exchanger on the heat exchanger unit.

[0037] Working principle: First, during assembly, the required number of heat exchanger plates 5 are stacked together in sequence along the four guide rods 4. After the stacking is completed, the horizontal screw 7 is driven to rotate by operating the No. 1 handwheel 9. Then, under the limit of the slide 6, the adjustment block 8 threadedly connected to the horizontal screw 7 will drive the locking plate 10 forward until it cannot move. At this time, all the stacked heat exchanger plates 5 can be tightened and fixed, thus completing the entire assembly work;

[0038] Secondly, during installation and debugging, the worm 16 on the control shaft 15 is driven to rotate by the No. 2 handwheel 17, and then the worm wheel 13 engaged with the worm 16 drives the angle adjustment shaft 12 to rotate. Since the engagement of the worm 16 and the worm wheel 13 is self-locking, the installation angle of the entire heat exchanger can be flexibly adjusted, thereby better meeting the complex pipeline connection requirements of the heat exchanger unit during installation and debugging.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
