An arc-shaped groove 71 is concavely provided in the middle part of the outer wall of the trigger ring 70. Trigger vertical plates 72 are respectively convexly provided on both sides of the top surface of the trigger ring 70. The trigger vertical plates 72 are slidably set in the vertical connecting slide groove 119. An electrical supporting block 73 is convexly provided on the outer top of each trigger vertical plate 72. The inner sides of the two electrical supporting blocks 73 are respectively slidably set in the two vertical supporting slide grooves 118.

[0042] For example, in one embodiment: the inlet end of the external temperature control device is connected to the heat exchange inlet pipe 121 through a pipe, and the return end pipe of the external temperature control device is connected to the heat exchange outlet pipe 122. An electric control valve is provided on the top of the quick-connect pipe 114. The bottom end of the quick-connect sleeve 50 is connected to the return end of the heat medium solution delivery device or the inlet pipe 113 of another segmented heat exchanger through a pipe. The top surface of the vertical support slide 118 is provided with an electrode sheet.

[0043] For example, in one embodiment: before heat exchange is required, the refrigerant solution is sent into the cavity inside the heat exchange part 12 through the heat exchange liquid inlet pipe 121. Since the heat exchange tube mounting elements 24 on the three heat exchange adjustment components 20 are alternately arranged up and down along the length direction of the heat exchange part 12, the refrigerant solution will be uniformly filled into the cavity inside the entire heat exchange part 12 under the guidance of the three heat exchange tube mounting elements 24, thereby uniformly cooling the cavity inside the heat exchange part 12 and the plurality of heat exchange tubes 32. At the same time, the four regulating motors 431 will be started to drive the regulating rotating bar 432 to rotate. Since one end of the regulating rotating bar 432 is connected to the linkage sliding shaft 45 3 is rotatably connected, and the other end of the regulating rotating bar 432 is rotatably connected with the closed regulating rod 434. When the regulating rotating bar 432 rotates, it will drive the closed regulating rod 434 to slide along the arc-shaped regulating slot 428, thereby driving the arc-shaped sealing plate 433 to follow and move along the arc-shaped slot 427 away from one end of the liquid guiding slot 420, so that the liquid guiding slot 420 is opened. At the same time, it will also drive the linkage sliding shaft 453 to move along the triggering arc-shaped slot 429. Since the inner end of the arc-shaped piece 425 is made of elastic material, the inner end of the arc-shaped piece 425 is deformed, so that the inner end of the arc-shaped piece 425 will be spiral, which accelerates the uniform flow and diffusion of the heat medium solution during subsequent heat exchange.

[0044] When heat exchange is required, the heat medium solution is put into the cavity inside the liquid inlet part 11 through the liquid inlet pipe 113 to form a heat exchange liquid flow. When the heat exchange liquid flow flows in from the liquid inlet pipe 113, it will impact the multiple spiral blades 411, thereby causing the driving drum 41 to rotate, thereby causing the inner gear ring 413 to rotate accordingly, causing the four planetary gears 415 to rotate accordingly, causing the outer gear ring 423, the connecting cross 422 and the mounting shaft 421 to rotate accordingly, causing the four linkage columns 424, the four arc-shaped sheets 425 and the linkage rotating disk 426 to rotate accordingly, thereby accelerating the heat exchange liquid flow to flow rapidly to one end of the heat exchange part 12, and flowing into the liquid inlet part 11 through the four liquid guide grooves 420. The inner end of the cavity, at the same time, when the linkage turntable 426 rotates, the conical gear ring 452 will follow the rotation, and because the conical gear rings 446 on the three conical liquid balancing blocks 442 are all meshed and connected with the conical gear ring 452, the conical liquid balancing block 442 will follow the rotation, and the heat exchange liquid flow entering the inner end of the cavity inside the liquid inlet part 11 will be re-diffused, ensuring that the heat exchange liquid flow is evenly diffused and passes through multiple heat exchange tube holes 311 and then to multiple heat exchange tubes 32, and then evenly exchanges heat and cools the refrigerant solution inside the heat exchange part 12, and finally enters the liquid outlet pipe 131 through the cavity inside the liquid outlet part 13, and then is led out to achieve uniform cooling of the heat medium solution and the refrigerant solution.

[0045] For example, in one embodiment: when the heat medium solution passes through the heat exchange tube 32, the refrigerant solution in the heat exchange part 12 is rapidly heated up. Due to the thermal expansion and contraction effect of the solution, the expanded refrigerant solution will be filled into the annular elastic tube 23, thereby causing the refrigerant solution stored in the annular elastic tube 23 to expand rapidly. Since the middle parts of the outer sides of the two rotating elastic annular sheets 231 are respectively rotatably installed on both sides of the annular groove 123, the distance between the two rotating elastic annular sheets 231 in the annular elastic tube 23 will gradually decrease from the outer edge to the center. Since the top of the rotating half-disc 22 is in contact with the inner edge of the outer side of one of the rotating elastic annular sheets 231, and the bottom of the rotating half-disc 22 is rotatably installed on the side of the annular groove 123 at the bottom of the fixed half-disc 21 through a torsion spring, the rotating half-disc 22 rotates outward to expand, thereby accelerating the guidance of the flow of the refrigerant solution and accelerating the flow speed of the refrigerant solution in the heat exchange part 12, so as to avoid excessive temperature differences inside the heat exchange part 12 during heat exchange.

[0046] For example, in one embodiment: when maintenance is required, the external temperature control device will be closed, and the quick connection sleeve 50 needs to be installed on the bottom of the outer wall of the quick connection pipe 114, and the top surface of the quick connection sleeve 50 is abutted against the bottom surface of the limit ring 117, and then the two connecting buckles 60 are rotated to move inward, so that the two connecting buckles 60 are respectively clamped in the two buckle clamping turntables 52. At the same time, when the two connecting buckles 60 rotate, the two arc-shaped trigger blocks 61 will follow the movement, and then push the arc-shaped groove 71 on the trigger ring 70, so that it moves upward along the quick connection ring groove 116, so that the return spring extends, so that the trigger vertical plate 72 follows the movement, and then the electrical abutment block 73 follows the movement, so that the top of the electrical abutment block 73 abuts on the electrode sheet on the top surface of the vertical abutment slide groove 118, and then sends a signal to the four control motors 431, so that the four control motors 431 are started, and The driving and regulating rotating bar 432 rotates in the opposite direction, so that the linkage sliding shaft 453 moves along the triggering arc groove 429, and the inner end of the arc piece 425 returns to its original state, so that the four arc pieces 425 and the four linkage columns 424 will be alternately arranged in the circumferential direction and abut against each other. At the same time, the closed regulating rod 434 will slide along the arc regulating groove 428, so that the arc sealing plate 433 moves along the arc groove 427 to the end adjacent to the liquid guiding groove 420, so that the liquid guiding groove 420 is closed, so that the incoming heat medium solution will flow back to the quick connection pipe 114, and enter the reflux end of the heat medium solution conveying equipment or another segmented heat exchanger through the quick connection sleeve 50, so as to inspect and repair the heat exchange area 12, the liquid outlet part 13 and the heat exchange tube assembly 30, that is, the area where material fatigue is prone to occur, so as to achieve the effect of not having to shut down the entire equipment, thereby reducing maintenance costs and downtime.
