[0035] With such a scheme, firstly, the hot pipe port 2 and the cold pipe port 3 are arranged on the surface of the heat exchanger body 1. Since the hot pipe port 2 and the cold pipe port 3 are arranged in two groups, the end flanges of the two groups of hot pipe ports 2 are respectively used to connect the inlet and outlet of the heat source, and then the end flanges of the two groups of cold pipe ports 3 are respectively used to connect the inlet and outlet of the cold water.

Under the action of the corrugated compensator 4, it can be used to compensate for the thermal expansion and contraction stress of the heat exchanger, as well as part of the axial force. By adjusting the screw 5, the length of the corrugated compensator 4 can be controlled, so as to To ensure the firmness of the bellows compensator 4 during installation, and then use the protective mechanism 6 to be sleeved on the surface of the adjusting screw 5, so that the protective mechanism 6 can be against and covered on the surface of the bellows compensator 4, so as to improve the protective effect of the bellows compensator 4, and then use the cooling mechanism 7 to be installed inside the protective mechanism 6, so that the inside of the protective mechanism 6 can be better supported, so as to ensure the firmness between the protective mechanism 6 and the surface of the bellows compensator 4, and the setting of the conversion mechanism 8 can enable it to be synchronously driven when the cooling mechanism 7 is working, so as to exchange the position of the water inside the protective mechanism 6, so as to ensure the effect of heat dissipation protection.

[0036] In one embodiment, reference Figure 4 and Figure 6, an adaptive thermal expansion compensation device for a heat exchanger, the heat exchanger is provided with a hot pipe port 2 and a cold pipe port 3 for connecting the thermal expansion compensation device, the thermal expansion compensation device comprises: a corrugated compensator 4, fixed at the end of the hot pipe port 2, for compensating the internal stress of the hot pipe port 2; an adjusting screw 5, installed on the surface of the corrugated compensator 4, for adjusting the spacing between the corrugated compensators 4; a protective mechanism 6, arranged on the surface of the adjusting screw 5, for resisting and protecting the surface of the corrugated compensator 4; a hollow annular water tank 1, fixed inside the corrugated compensator 4, for cooling the protective mechanism 6; a cooling mechanism 7, fixed inside the protective mechanism 6, and the end of which is connected to the hollow annular water tank 1, for protecting the protective mechanism Water circulates inside the structure 6; when the cooling mechanism 7 moves downward, the protective mechanism 6 can be tightly fitted to the surface of the corrugated compensator 4; the flow conversion mechanism 8 is fixed at the end of the cooling mechanism 7, for converting the water inside the protective mechanism 6, the number of adjusting screws 5 and protective mechanisms 6 are both arranged in multiple groups, the number of adjusting screws 5 and protective mechanisms 6 are equal, the protective mechanism 6 is used to cover and protect the surface of the corrugated compensator 4, the protective mechanism 6 includes a mounting component 61 adjusted on the surface of the adjusting screw 5, the interior of the mounting component 61 is penetrated by a ratchet rod 62, the end of the ratchet rod 62 is fixedly connected to a fixing plate 63, the end of the fixing plate 63 is fixedly connected to a protective water bag 64, the protective water bag 64 is tightly fitted to the surface of the corrugated compensator 4.

[0037] By adopting such a scheme, the protective mechanism 6 can be installed on the surface of the adjusting screw 5, and then adhered to the surface of the corrugated compensator 4, so that it can cover the surface of the corrugated compensator 4, thereby providing support, cooling and other protective functions for the surface of the corrugated compensator 4, and preventing the corrugated compensator 4 from becoming unstable and deforming due to excessive temperature.

[0038] During specific operation, the installation component 61 is first sleeved on the surface of the adjusting screw 5, and then the ratchet rod 62 penetrates into the interior of the installation component 61, so that the protective water bag 64 fixed by the fixing plate 63 can be located on the surface of the corrugated compensator 4. At the same time, the ratchet rod 62 is adjusted inside the installation component 61, so that the protective water bag 64 can be more closely attached to the surface of the corrugated compensator 4, so that the surface of the corrugated compensator 4 can be supported, cooled and protected, to prevent the corrugated compensator 4 from becoming unstable and deformed due to excessive internal temperature.

[0039] In addition, a water injection pipe is provided on the surface of the protective water bag 64 to prevent the coolant from being lost and refilled later.

[0040] In one embodiment, reference Figure 4 and Figure 6The cooling mechanism 7 includes a piston cylinder 71 fixed inside the mounting assembly 61, a piston block 72 is slidably connected inside the piston cylinder 71, a piston rack 73 is fixedly connected to the end of the piston block 72, an inlet pipe 74 and a drain pipe 78 are respectively connected on both sides of the piston cylinder 71, and a one-way valve is provided on the surface of the inlet pipe 74 and the drain pipe 78, the end of the inlet pipe 74 passes through the mounting assembly 61 and is connected to the surface of the hollow annular water tank 1, an arc pressure ring 75 is fixedly connected to the end of the piston rack 73, and the arc pressure ring 75 is used to be clamped on the surface of the bellows compensator 4, a limiting block 76 is fixedly connected inside the piston cylinder 71, and the limiting block 76 is used to limit the bottom of the piston block 72, and a return spring 77 is fixedly connected to the inner top wall of the piston cylinder 71, and the end of the return spring 77 contacts the surface of the piston block 72.

[0041] By adopting such a scheme, the cooling mechanism 7 is arranged in two groups, so that when the protective water bag 64 is compressed, the two groups of cooling mechanisms 7 can be driven upward synchronously. When the first group of cooling mechanisms 7 is in a compressed state, the one-way valve on the water inlet pipe 74 can be closed, and the one-way valve on the drain pipe 78 can be opened, so that the coolant inside the piston cylinder 71 can be discharged into the protective water bag 64 through the drain pipe 78. Since the second group of cooling mechanisms 7 is arranged in the opposite way, when the second group of cooling mechanisms 7 is in a compressed state, the one-way valve on the water inlet pipe 74 can be opened, and the one-way valve on the drain pipe 78 can be closed, so that the coolant inside the piston cylinder 71 can be discharged into the hollow annular water tank 1 through the water inlet pipe 74.

[0042] When the two groups of cooling mechanisms 7 are reset, the two groups of cooling mechanisms 7 can be released synchronously. When the first group of cooling mechanisms 7 is in the released state, the one-way valve on the water inlet pipe 74 can be opened, and the one-way valve on the drain pipe 78 can be closed, so as to extract the coolant inside the hollow annular water tank 1 into the piston cylinder 71, so as to facilitate discharge during the next reset. Because the second group of cooling mechanisms 7 is set in the opposite way, when the second group of cooling mechanisms 7 is in the released state, the one-way valve on the water inlet pipe 74 can be closed, and the one-way valve on the drain pipe 78 can be opened, so as to extract the coolant inside the protective water bag 64 into the piston cylinder 71, so as to facilitate the later discharge of the coolant into the hollow annular water tank 1.

[0043] In specific operation, when in use, it is first installed inside the protective water bag 64 through the piston cylinder 71, and then the piston rack 73 can be driven upward when the protective water bag 64 is compressed by the deformation of the corrugated compensator 4. When the piston rack 73 is driven, the piston block 72 can be moved upward inside the piston cylinder 71, so that the coolant inside the piston cylinder 71 can be compressed, and the compressed coolant is transported to the inside of the protective water bag 64 through the drain pipe 78, so as to replenish the coolant inside the protective water bag 64 with new coolant for cooling treatment, so as to prevent the protective effect from being affected by the excessively high temperature inside the protective water bag 64, and when the piston rack 73 is driven, the piston block 72 can be moved downward inside the piston cylinder 71, which can reduce the temperature of the single The valve is opened to extract the coolant inside the hollow annular water tank 1, so as to facilitate the replacement of the coolant next time. Under the setting of the arc pressure ring 75, it is located inside the corrugated end of the bellows compensator 4, and then under the setting of two groups of arc pressure rings 75, it is used to limit the two ends of the protective water bag 64, so as to ensure that the protective water bag 64 fits more closely to the surface of the bellows compensator 4, and then through the setting of the limit block 76, it can limit the bottom of the piston block 72 to prevent the piston block 72 from being separated from the inside of the piston cylinder 71. Finally, through the setting of the reset spring 77, it can apply pressure to the top of the piston block 72 to reset the piston block 72, thereby ensuring that the piston rack 73 can fit tightly inside the protective water bag 64.

[0044] In addition, since the protection mechanism 6 is arranged in multiple groups, and the cooling mechanism 7 is also arranged in multiple groups, it is possible to set the multiple cooling mechanisms 7 to be opposite, so that the coolant inside the two hollow annular water tanks can be extracted to achieve water circulation.

[0045] In one embodiment, referring to Figure 4 and Figure 7, an adaptive thermal expansion compensation device for a heat exchanger, the heat exchanger is provided with a hot pipe port 2 and a cold pipe port 3 for connecting the thermal expansion compensation device, the thermal expansion compensation device comprises: a corrugated compensator 4, fixed at the end of the hot pipe port 2, for compensating the internal stress of the hot pipe port 2; an adjusting screw 5, installed on the surface of the corrugated compensator 4, for adjusting the spacing between the corrugated compensators 4; a protective mechanism 6, arranged on the surface of the adjusting screw 5, for resisting and protecting the surface of the corrugated compensator 4; a hollow annular water tank 1, fixed inside the corrugated compensator 4, for cooling the protective mechanism 6; a cooling mechanism 7, fixed inside the protective mechanism 6, and the end of which is connected to the hollow annular water tank 1, for circulating water inside the protective mechanism 6; When the cooling mechanism 7 moves downward, the protective mechanism 6 can be tightly fitted on the surface of the corrugated compensator 4; the flow conversion mechanism 8 is fixed at the end of the cooling mechanism 7, and is used to convert the water inside the protective mechanism 6. The number of adjusting screws 5 and protective mechanisms 6 are both set in multiple groups, and the number of adjusting screws 5 and protective mechanisms 6 is equal. The protective mechanism 6 is used to cover and protect the surface of the corrugated compensator 4. The flow conversion mechanism 8 includes a hollow cylinder 81 fixed at the end of the piston cylinder 71, and the interior of the hollow cylinder 81 is rotatably connected to a rotating shaft 82 through a bracket. A gear 83 is fixedly connected to the middle of the rotating shaft 82, and the gear 83 is meshed with the surface of the piston rack 73. The end of the piston rack 73 slides inside the hollow cylinder 81, and both ends of the rotating shaft 82 are fixedly connected to a turbine 84.

[0046] By adopting such a scheme, the cooling mechanism 7 synchronously drives the flow conversion mechanism 8 for synchronous driving. When the cooling mechanism 7 moves upward, it can drive the flow conversion mechanism 8 to rotate clockwise, so as to extract the inner edge of the protective water bag 64 to the middle part. When the cooling mechanism 7 is released, it can drive the flow conversion mechanism 8 to rotate counterclockwise, so as to move the coolant in the middle of the protective water bag 64 to both sides, so as to reverse the coolant inside the protective water bag 64, so as to reduce the temperature of the coolant inside the protective water bag 64, so that when the flow conversion mechanism 8 is driven, the water flow at the inner edge of the protective water bag 64 can be moved to the middle part, and the cold water at the edge of the protective water bag 64 and the heated water in the middle of the protective water bag 64 can be subjected to heat exchange and cooling treatment by means of water flow conversion, so as to further promote the internal protection effect of the protective water bag 64.

[0047] During specific operation, first, the hollow cylinder 81 is fixed to the end of the piston cylinder 71, so that when the piston rack 73 moves upward, the gear 83 meshing on the surface of the piston rack 73 can be rotated, and the rotating shaft 82 can be rotated under the rotation of the gear 83, and the rotation of the rotating shaft 82 can synchronously drive the turbine 84 to rotate. When the turbine 84 rotates, the coolant at the edge of the protective water bag 64 can be extracted, and then released to the middle of the protective water bag 64, so that it can be mixed with the coolant in the middle, so as to prevent the coolant in the middle of the protective water bag 64 from being too hot, resulting in reduced protection effect, and other problems. Since the number of turbines 84 is set in two groups, and the two groups are directional settings, the efficiency is faster and the effect is better when pumping water.

[0048] In addition, when there are two sets of turbines 84 , the two sets of turbines 84 are arranged in the same direction so that they can only rotate in the same direction when working, so as to better exchange and cool the coolant inside the protective water bag 64 .

[0049] In one embodiment, referring to Figure 8 The mounting assembly 61 includes a mounting sleeve 611 that passes through the surface of the adjusting screw 5. Both ends of the mounting sleeve 611 are fixedly connected to the limiting sub-blocks 612. The inside of the limiting sub-block 612 is rotatably connected to a stop pawl 613 through a rotating shaft. The stop pawl 613 is used to abut against the surface of the ratchet rod 62. The inside of the limiting sub-block 612 is connected to a spring sheet 614, and the end of the spring sheet 614 is fixed to the surface of the stop pawl 613.

[0050] By adopting such a scheme, when the ratchet rod 62 is installed inside the mounting assembly 61, it can adjust the lowering distance of the fixing plate 63 as needed, and the pressure of the protective water bag 64 can be adjusted during the lowering process of the fixing plate 63, so as to better fit the protective water bag 64 to the surface of the corrugated compensator 4.

[0051] During specific operation, first, the installation sleeve 611 is passed through the surface of the adjusting screw 5 and fixed in the middle of the adjusting screw 5, and then the head of the ratchet rod 62 is passed from bottom to top to the inside of the limiting sub-block 612. Under the setting of the anti-retraction pawl 613, the surface of the ratchet rod 62 can be limited, so that the ratchet rod 62 can only move in one direction. Under the setting of the spring sheet 614, the anti-retraction pawl 613 can be automatically reset, so that the anti-retraction pawl 613 is tightly fitted inside the ratchet rod 62 teeth, thereby realizing the pressure adjustment locking of the fixing plate 63.

[0052] During disassembly, it is only necessary to compress the stop pawl 613 backwards so that it can compress the spring sheet 614 , thereby removing the ratchet rod 62 from the interior of the mounting assembly 61 .

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
