[0031] like Figure 2 , Figure 3 and Figure 6 As shown, two groups of inlet pipes 410 and outlet pipes 420 respectively pass through a plurality of heat exchange plates 30 along the length direction of the sealed shell 20, and are rotatably assembled on the sealed shell 20. Each group of inlet pipes 410 and outlet pipes 420 is respectively provided with a plurality of flow openings 430 along the length direction of the sealed shell 20. The flow openings 430 of one group of inlet pipes 410 and outlet pipes 420 are used to connect with each cold channel 510, and are used to inject and discharge cold heat exchange fluid into the cold channel 510, and the flow openings 430 of another group of inlet pipes 410 and outlet pipes 420 are used to connect with each hot channel 520, and are used to inject and discharge hot heat exchange fluid into the hot channel 520. Each group of inlet pipes 410 and outlet pipes 420 is respectively provided with an external spline 440 corresponding to the cold channel 510 or the hot channel 520.

[0032] like Figure 2 As shown, each motor 90 is connected to the inlet pipe 410 or the outlet pipe 420 via a transmission belt 910 to drive the inlet pipe 410 and the outlet pipe 420 to rotate.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the two groups of cleaning components correspond to the cold channel 510 and the hot channel 520 respectively. Furthermore, in other embodiments, due to the different types and properties of the hot side fluid and the cold side fluid, the formation of scale and sediment may be affected. If the hot channel 520 is prone to mineral precipitation and scaling due to the high temperature, only one group of cleaning components corresponding to the hot channel 520 can be set according to the cleaning requirements, and the inlet pipe 410 and the outlet pipe 420 corresponding to the hot channel 520 are rotatably assembled on the sealing shell 20, and the other group of inlet pipe 410 and the outlet pipe 420 can be fixed on the sealing shell 20. Each cleaning component includes a drug inlet pipe 610, a drug outlet pipe 620, a plurality of distribution pipes 630, a plurality of trigger plugs 70 and a plurality of transmission rings 80.

[0034] The drug inlet pipe 610 and the drug outlet pipe 620 are fixed outside the sealed shell 20 and communicate with the outside through the outer shell 10. The drug inlet pipe 610 and the drug outlet pipe 620 are respectively connected with a plurality of distribution pipes 630 along the length direction of the sealed shell 20, which are used to connect the cold channel 510 or the hot channel 520 to fill and discharge the cleaning agent into the cold channel 510 or the hot channel 520.

[0035] like Figure 3 and Figure 5 As shown, the distribution pipe 630 is provided with a medicine-passing port 632 communicating with the cold channel 510 or the hot channel 520, and a trigger plug 70 for blocking or opening the medicine-passing port 632 is movably mounted in the distribution pipe 630. The trigger plug 70 includes an opening and closing cylinder 710, a transmission shaft 740, and a trigger body 720. The opening and closing cylinder 710 is sleeved in the distribution pipe 630, and the opening and closing cylinder 710 has a communication port 711 that can communicate with the medicine-passing port 632. The outer wall of the opening and closing cylinder 710 is spirally driven with the inner wall of the distribution pipe 630. Specifically, the inner wall of the distribution pipe 630 has a spiral slide groove, and the outer wall of the opening and closing cylinder 710 has a slider that slides with the slide groove. The transmission shaft 740 is a square shaft, which is fixedly connected to the opening and closing cylinder 710 and slides through the trigger body 720 along the axial direction of the distribution tube 630. The trigger body 720 is rotatably connected to the distribution tube 630, so that the opening and closing cylinder 710 moves along the axial direction of the distribution tube 630 and rotates around its axis, thereby driving the trigger body 720 to rotate through the transmission shaft 740. A second spring 730 is provided between the opening and closing cylinder 710 and the distribution tube 630 to apply elastic force to the opening and closing cylinder 710 to reset the trigger plug 70. In this embodiment, the opening and closing cylinder 710 in the distribution tube 630 on the drug inlet tube 610 is pushed by the positive pressure in the drug inlet tube 610. When it moves toward the corresponding trigger body 720, the communication port 711 on the opening and closing cylinder 710 is connected with the corresponding drug outlet 632. The opening and closing cylinder 710 in the distribution tube 630 on the drug outlet tube 620 is sucked by the negative pressure in the drug inlet tube 610. When it moves away from the corresponding trigger body 720, the communication port 711 on the opening and closing cylinder 710 is connected with the corresponding drug outlet 632.

[0036] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the transmission ring 80 is movably sleeved outside the inlet pipe 410 and the outlet pipe 420 along the length direction of the sealing shell 20, and is located in each cold channel 510 or hot channel 520. The transmission ring 80 includes a first ring body 810, a second ring body 820 and a connecting column 830. A plurality of connecting columns 830 are connected between the first ring body 810 and the second ring body 820, and the inner side of the first ring body 810 has an inner spline 811 corresponding to the outer spline 440. The outer side of the first ring body 810 has a transmission groove 812 that is slidably matched with the transmission block. The transmission groove 812 includes a spiral groove 812a and a straight groove 812b extending radially along the transmission ring 80. The straight groove 812b connects the head and tail ends of the spiral groove 812a. A first spring 322 is provided between the moving plate 320 and the static plate 310 to apply elastic force to the moving plate 320 so that the moving plate 320 is close to the static plate 310 along the straight groove 812b. The second ring body 820 is fixedly connected to the switch plate 840 via a fixing rod 841 . The switch plate 840 is movable along the length direction of the sealing shell 20 and assembled at the flow openings 430 of the inlet pipe 410 and the outlet pipe 420 to block or open the flow openings 430 .

[0037] The working process of the embodiment of the heat exchanger structure based on the automobile of the present invention comprises the following steps:

[0038] In the first step, when the heat exchanger is working normally, the flow ports 430 of the two groups of inlet and outlet pipes 410 and 420 respectively fill and discharge the cold and hot heat exchange fluids into the cold channel 510 and the hot channel 520, and the drug flow ports 632 of the distribution pipes 630 on the drug inlet pipe 610 and the drug outlet pipe 620 are blocked by the trigger plug 70, and the cold and hot heat exchange fluids exchange heat through the heat exchange plate 30.

[0039] In the second step, when the heat exchanger needs to be cleaned, the drug inlet pipe 610 introduces the cleaning agent into the corresponding distribution pipe 630, and the drug outlet pipe 620 extracts the cleaning agent from the corresponding distribution pipe 630. The opening and closing cylinder 710 in the distribution pipe 630 moves along the axial direction of the distribution pipe 630 and rotates around its axial direction, so that the connecting port 711 is connected with the drug passing port 632, and the cleaning agent can flow between the distribution pipe 630 and the cold channel 510 or the hot channel 520, and the opening and closing cylinder 710 drives the trigger body 720 to rotate through the transmission shaft 740, and the trigger body 720 pushes the transmission ring 80 to move along the length direction of the sealing shell 20, so that the inner spline 811 cooperates with the outer spline 440 and the switch plate 840 closes the flow port 430.

[0040] In the third step, each motor 90 drives the inlet pipe 410 and the outlet pipe 420 to rotate, and the transmission ring 80 rotates with the inlet pipe 410 and the outlet pipe 420. The transmission ring 80 drives the movable plate 320 to reciprocate in the cold channel 510 or the hot channel 520 through the transmission groove 812 to clean the heat exchange surfaces on both sides of the cold channel 510 or the hot channel 520. At the same time, the connecting column 830 can push the pushing part 323a to drive the vibration plate 323 to vibrate, so that the vibration plate 323 assists the movable plate 320 to vibrate.

[0041] In this way, the automobile-based heat exchanger structure sets a cleaning component in the heat exchanger, so that the cleaning component can clean and descale the heat exchange surface on one side of the heat exchange plate 30 or the heat exchange surfaces on both sides of the heat exchange plate 30 according to the cleaning requirements of different heat exchange fluids, and when cleaning the heat exchange surface, the heat exchange fluid in a single fluid channel can be discharged, and the cleaning agent can be added and discharged separately, and the heat exchange surfaces on both sides of the fluid channel can be cleaned by moving the moving plate 320. There is no need to shut down the engine, and the interior of the automobile's heat exchanger can be cleaned online, allowing the vehicle to gradually remove scale and various deposits during normal use, which helps to maintain the optimal heat exchange efficiency of the heat exchanger and ensure that the vehicle's cooling system is always in good working condition.

[0042] The present invention also provides an embodiment of a thermal management system based on an automobile. On the basis of the above-mentioned embodiment of the heat exchanger structure based on an automobile, each distribution pipe 630 is provided with a solenoid valve 631 for controlling the on and off of the cleaning agent in the distribution pipe 630. In this way, each cold channel 510 and hot channel 520 can be cleaned separately according to the actual situation, or the cold channel 510 and the hot channel 520 can be cleaned one by one, making the cleaning process more flexible, avoiding uniform large-scale cleaning of all fluid channels, and improving the convenience of cleaning.
