Description

Technical Field

[0001] This invention relates to the field of temperature control valves, specifically a temperature control valve and a temperature control method. Background Technology

[0002] Paraffin wax thermostatic valves are a type of temperature control valve that uses a paraffin wax element as the sensing element. When the temperature changes, the paraffin wax element responds quickly and pushes the valve core to control the temperature within the set range. Paraffin wax thermostatic valves have a large thrust, and the internal paraffin wax can expand to more than 200 atmospheres. They have a good linearity in the stroke-temperature curve, resulting in strong temperature control capability. The element has high rigidity, high strength, and long service life. They can be used in engine cooling systems to control the small and large circulation of coolant by controlling the coolant temperature. In the small circulation, the coolant flows directly back to the engine, while in the large circulation, it first passes through the radiator to dissipate heat before flowing back to the engine. This allows for control of the engine temperature, ensuring cooling effect while being more energy-efficient and environmentally friendly.

[0003] However, when using existing paraffin temperature control valves, the expanded paraffin inside the valve is not heated evenly, affecting the efficiency and effect of expansion, which in turn affects the accuracy of temperature control. Furthermore, it is not convenient to adjust the temperature when switching between small and large circulation of coolant, resulting in poor applicability and affecting the performance. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a temperature control valve and a temperature control method.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a temperature control valve, comprising an engine, a temperature control valve body, and a radiator installed in an engine cooling system. The temperature control valve body includes an inlet pipe, a first outlet pipe, and a second outlet pipe. A first pipe is fixedly connected between the inlet pipe and the engine. A second pipe is fixedly connected between the first outlet pipe and the engine. A third pipe is fixedly connected between the second outlet pipe and the radiator. A fourth pipe is fixedly connected between the radiator and the engine. A hollow tube is fixedly connected inside the temperature control valve body. Multiple arrayed inlet holes are opened on the side wall of the hollow tube near the inlet pipe. Multiple arrayed first outlet holes are opened on the side wall of the hollow tube near the first outlet pipe. Multiple arrayed second outlet holes are opened at the bottom of the hollow tube. A movable rod is inserted, with a connecting block fixedly connected to the upper end of the movable rod, and a sealing plate fixedly connected to the side wall of the connecting block. The side wall of the sealing plate has multiple arrayed first through holes, and a sealing disc is fixedly connected to the lower end of the movable rod. Multiple arrayed second through holes are opened at the bottom of the sealing disc. A first fixed rod is fixedly connected to the inner wall of the liquid inlet pipe, and a storage tube is fixedly connected to the lower end of the first fixed rod. The storage tube is filled with expanded paraffin wax, and a movable disc is slidably connected inside the storage tube. A sliding rod is fixedly connected to the end of the movable disc, and the other end of the sliding rod is rotatably connected to a connecting rod, which is rotatably connected to the top of the connecting block. An agitation mechanism for stirring the expanded paraffin wax is provided inside the storage tube, and a resistance mechanism for providing resistance to the movement of the sliding rod is provided inside the hollow tube.

[0006] The stirring mechanism includes a second fixed rod fixedly connected to the inner wall of the storage tube, and a fixed ring fixedly connected to the other end of the second fixed rod. A first rotating shaft is rotatably connected inside the fixed ring, and a rotating disk is fixedly connected to one end of the first rotating shaft. A plurality of arrayed stirring rods are fixedly connected to the end of the rotating disk. The expanded paraffin wax is filled between the rotating disk and the storage tube, and the rotation of the first rotating shaft is driven by a driving mechanism.

[0007] The drive mechanism includes a second rotating shaft rotatably connected to the end of the storage tube. One end of the second rotating shaft is fixedly connected to a fan, and the other end of the second rotating shaft is connected to the first rotating shaft through a flexible connection mechanism.

[0008] The flexible connection mechanism includes a first ring fixedly sleeved on the side wall of the first rotating shaft, and a second ring fixedly sleeved on the side wall of the second rotating shaft. The end of the first ring has a plurality of arrayed slots, and the end of the second ring is connected to a plurality of arrayed blocks through a telescopic mechanism. The blocks are inserted into the slots, and each block includes two symmetrically arranged first inclined surfaces.

[0009] The telescopic mechanism includes a plurality of arrayed T-shaped guide rods inserted into the end of the second ring, and the side wall of the T-shaped guide rod is provided with a plane. One end of the T-shaped guide rod is fixed to the side wall of the locking block, and a first spring is sleeved on the side wall of the T-shaped guide rod.

[0010] The resistance mechanism includes a sleeve fixedly inserted at the top of the hollow tube, and a sleeve rod connected to the bottom of the sleeve through a compression mechanism. A resistance block is fixedly connected to the lower end of the sleeve rod, and the resistance block includes a second inclined surface.

[0011] The extrusion mechanism includes a first sliding disc slidably connected inside the sleeve, and a second spring is fixedly connected to the bottom of the first sliding disc. The lower end of the second spring is fixedly connected to the second sliding disc, and the second sliding disc slides inside the sleeve. The upper end of the sleeve rod is fixed to the bottom of the second sliding disc, and the movement of the first sliding disc is driven by a pushing mechanism.

[0012] The pushing mechanism includes a first pushing rod fixedly connected to the top of the second sliding plate, and a fixed tube fixedly connected to the side wall of the temperature control valve body. A sealing cap is threadedly connected to the side wall of the fixed tube, and a second pushing rod is fixedly connected to the bottom of the sealing cap. An marking mechanism is provided on the side wall of the first liquid outlet pipe.

[0013] The marking mechanism includes a marking plate fixedly connected to the side wall of the first liquid outlet pipe, and the surface of the marking plate is provided with scale markings. An indicator ring is fixedly sleeved on the side wall of the sealing cap.

[0014] A temperature control method, utilizing the temperature control valve described above, includes the following steps:

[0015] S1: During use, the coolant after cooling the engine enters the second outlet pipe through the first pipe and the inlet pipe. When the engine temperature is low, the coolant temperature is also low. At this time, the expansion of the expanded paraffin in the storage pipe is small. At this time, the moving plate and the sliding rod do not move. At this time, the sealing plate seals the second outlet hole. The coolant returns to the engine through the first through hole and the first outlet hole, and then through the first outlet pipe and the second pipe.

[0016] S2: When the engine temperature is high, the circulating coolant temperature is also high. At this time, the expanded paraffin in the storage tube expands and pushes the moving disc and sliding rod to move. The movement of the sliding rod drives the connecting rod to rotate, which in turn drives the connecting block and moving rod to move downward. When the moving rod moves downward, it drives the sealing plate and sealing disc to move downward synchronously. At this time, the first through hole and the first outlet hole are misaligned, so that the sealing plate can block and seal the first outlet hole. The coolant then enters the radiator through the second outlet hole and the second through hole, and then through the second outlet pipe and the third pipe for cooling. After cooling, the coolant circulates back into the engine through the fourth pipe. This process is repeated to control the engine temperature, ensuring its cooling effect while being more energy-efficient and environmentally friendly.

[0017] S3: When the coolant is circulating, when the coolant enters the inlet pipe, it impacts the surface of the fan and makes it rotate. The rotation of the fan drives the rotation of the second shaft, which in turn drives the rotation of the second ring. Through the locking block, the first ring rotates, which in turn drives the first shaft and the rotating disk to rotate. This causes the stirring rod to stir the expanded paraffin in the storage tube, making its heat absorption and expansion more efficient and effective, thus ensuring the accuracy of temperature control.

[0018] S4: When the expanded paraffin wax expands to a large volume, the extrusion force on the stirring rod is large. At this time, the resistance of the first rotating shaft is large. When the second rotating shaft rotates, the first inclined surface slides on the side wall of the slot and the block slides out of the slot. At the same time, the first spring is compressed, which ensures that the second rotating shaft and the fan can rotate normally, while the first rotating shaft stops rotating, avoiding large resistance to the flow of coolant and ensuring the normal circulation effect of coolant.

[0019] S5: When the expanded paraffin wax in the storage tube expands due to heat, it pushes the moving disc and sliding rod to move. When the thrust is greater than the resistance of the resistance block on the sliding rod, one end of the sliding rod slides on the second inclined plane and pushes the resistance block upward. The movement of the resistance block drives the movement of the sleeve rod and the second sliding disc, and compresses the second sliding disc. The resistance block can resist the movement of the sliding rod. Furthermore, by rotating the sealing cover, the sealing cover drives the second push rod downward, which in turn pushes the first push rod downward. The movement of the first push rod drives the first sliding disc downward, thereby adjusting the compression of the second spring, that is, adjusting the squeezing force of the second spring on the second sliding disc, thereby adjusting the resistance of the resistance block on the sliding rod, and thus regulating and controlling the temperature of the coolant when switching between the first and second outlet pipes. This makes it more applicable and has a better performance.

[0020] The beneficial effects of this invention are:

[0021] (1) The temperature control valve and temperature control method of the present invention, by setting up a stirring mechanism, etc., allows the coolant after the engine is cooled to enter the second outlet pipe through the first pipe and the inlet pipe. When the engine temperature is low, the coolant temperature is also low. At this time, the expansion amount of the expanded paraffin in the storage pipe is small. At this time, the moving plate and the sliding rod do not move. At this time, the sealing plate seals the second outlet hole. The coolant returns to the engine through the first through hole and the first outlet hole, and then through the first outlet pipe and the second pipe. When the engine temperature is high, the circulating coolant temperature is high. At this time, the expansion amount of the expanded paraffin in the storage pipe increases. The expansion of the slide bar pushes the moving disc and sliding rod to move. The movement of the sliding rod drives the connecting rod to rotate, which in turn drives the connecting block and the moving rod to move downward. When the moving rod moves downward, it drives the sealing plate and the sealing disc to move downward synchronously. At this time, the first through hole and the first liquid outlet hole are misaligned, so that the sealing plate can block and seal the first liquid outlet hole. This allows the coolant to enter the radiator through the second liquid outlet hole and the second through hole, and then through the second liquid outlet pipe and the third pipe for cooling. After cooling, the coolant circulates back into the engine through the fourth pipe. This process is repeated to control the engine temperature, ensuring its cooling effect while being more energy-efficient and environmentally friendly.

[0022] (2) The temperature control valve and temperature control method of the present invention, by setting a drive mechanism and a soft connection mechanism, etc., when the coolant is circulating, when the coolant enters the inlet pipe, it impacts the surface of the fan and makes it rotate. The rotation of the fan drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the second ring, and drives the first ring to rotate through the locking block, thereby driving the first rotating shaft and the rotating disk to rotate, so that the stirring rod stirs the expanded paraffin in the storage tube, making its heat absorption and expansion more efficient and effective, thereby ensuring the accuracy of temperature control. Moreover, when the expanded paraffin has a large expansion volume, the squeezing force on the stirring rod is large. At this time, the resistance of the first rotating shaft is large. When the second rotating shaft rotates, the first inclined surface slides on the side wall of the slot and the locking block slides out of the slot. At the same time, the first spring is compressed, which ensures that the second rotating shaft and the fan can rotate normally, while the first rotating shaft no longer rotates, avoiding large resistance to the flow of coolant and ensuring the normal circulation effect of coolant.

[0023] (3) The temperature control valve and temperature control method of the present invention, by setting a pushing mechanism, etc., when the expanded paraffin in the storage tube is heated and expands, it pushes the moving disk and sliding rod to move. When the pushing force is greater than the resistance of the resistance block on the sliding rod, one end of the sliding rod slides on the second inclined surface and pushes the resistance block to move upward. The movement of the resistance block drives the movement of the sleeve rod and the second sliding disk, and causes the second sliding disk to be compressed. The resistance block can resist the movement of the sliding rod. Furthermore, by rotating the sealing cover, the sealing cover drives the second pushing rod to move downward, thereby pushing the first pushing rod to move downward. The movement of the first pushing rod drives the first sliding disk to move downward, thereby adjusting the compression of the second spring, that is, adjusting the squeezing force of the second spring on the second sliding disk, thereby adjusting the resistance of the resistance block on the sliding rod, and thus regulating and controlling the temperature of the coolant when switching between the first and second outlet pipes. It has stronger applicability and better performance. Attached Figure Description

[0038] like Figures 1-10 As shown, a temperature control valve of the present invention includes an engine 10, a temperature control valve body 1, and a radiator 11 disposed in an engine cooling system. The temperature control valve body 1 includes an inlet pipe 101, a first outlet pipe 102, and a second outlet pipe 103. A first pipe 12 is fixedly connected between the inlet pipe 101 and the engine 10. A second pipe 15 is fixedly connected between the first outlet pipe 102 and the engine 10. A third pipe 13 is fixedly connected between the second outlet pipe 103 and the radiator 11. The radiator 11 and the engine 10 are also fixedly connected. A fourth pipe 14 is fixedly connected to the body of the temperature control valve 1. A hollow tube 16 is fixedly connected inside the body of the temperature control valve 1. The hollow tube 16 has multiple arrayed liquid inlet holes 17 on its side wall near the liquid inlet pipe 101, and multiple arrayed first liquid outlet holes 22 on its side wall near the first liquid outlet pipe 102. Multiple arrayed second liquid outlet holes 18 are opened at the bottom of the hollow tube 16. A moving rod 19 is inserted into the bottom of the hollow tube 16. A connecting block 23 is fixedly connected to the upper end of the moving rod 19, and a sealing plate 2 is fixedly connected to the side wall of the connecting block 23. 4. The side wall of the sealing plate 24 has multiple arrayed first through holes 30, and the lower end of the moving rod 19 is fixedly connected to the sealing disc 20. The bottom of the sealing disc 20 has multiple arrayed second through holes 21, and the inner side wall of the liquid inlet pipe 101 is fixedly connected to the first fixing rod 25. The lower end of the first fixing rod 25 is fixedly connected to the storage tube 26, and the storage tube 26 is filled with expanded paraffin wax. The moving disc 27 is slidably connected inside the storage tube 26, and the end of the moving disc 27 is fixedly connected to the sliding rod 28. The other end of the sliding rod 28 rotates. The device is connected to a connecting rod 29, with the other end of the connecting rod 29 rotatably connected to the top of the connecting block 23. The storage tube 26 is equipped with an agitation mechanism for stirring the expanded paraffin wax, and the hollow tube 16 is equipped with a resistance mechanism for providing resistance to the movement of the sliding rod 28. It can use the flow of coolant as power to stir the expanded paraffin wax in the storage tube 26, making its heat absorption and expansion more efficient and effective, thereby ensuring the accuracy of temperature control. In addition, it is convenient to adjust the temperature of the temperature-controlled coolant, making it more applicable and having a better performance.

[0039] The stirring mechanism includes a second fixed rod 201 fixedly connected to the inner wall of the storage tube 26, and a fixed ring 202 fixedly connected to the other end of the second fixed rod 201. A first rotating shaft 203 is rotatably connected inside the fixed ring 202, and a rotating disk 204 is fixedly connected to one end of the first rotating shaft 203. A plurality of arrayed stirring rods 205 are fixedly connected to the end of the rotating disk 204. Expanded paraffin wax is filled between the rotating disk 204 and the storage tube 26. The rotation of the first rotating shaft 203 is driven by a drive mechanism. When the coolant is circulating, the drive mechanism drives the first rotating shaft 203 to rotate. The rotation of the first rotating shaft 203 drives the rotating disk 204 to rotate, thereby causing the stirring rods 205 to stir the expanded paraffin wax in the storage tube 26, making its heat absorption and expansion more efficient and effective, thus ensuring the accuracy of temperature control.

[0040] The drive mechanism includes a second rotating shaft 301 rotatably connected to the end of the storage tube 26. One end of the second rotating shaft 301 is fixedly connected to a fan 302, and the other end of the second rotating shaft 301 is connected to the first rotating shaft 203 through a flexible connection mechanism. When coolant enters the inlet pipe 101, it impacts the surface of the fan 302, causing it to rotate. The rotation of the fan 302 drives the rotation of the second rotating shaft 301, and drives the first rotating shaft 203 to rotate through the flexible connection mechanism.

[0041] The flexible connection mechanism includes a first ring 401 fixedly sleeved on the side wall of the first rotating shaft 203, and a second ring 402 fixedly sleeved on the side wall of the second rotating shaft 301. The end of the first ring 401 has multiple arrayed slots 403, and the end of the second ring 402 is connected to multiple arrayed blocks 404 via a telescopic mechanism. The blocks 404 are inserted into the slots 403 and include two symmetrically arranged first inclined surfaces 405. The rotation of the second rotating shaft 301 drives the rotation of the second ring 402, which in turn drives the first ring 401 to rotate via the blocks 404, thereby driving the first rotating shaft 203. The rotation of the rotating disk 204 and the agitator 205 agitates the expanded paraffin wax in the storage tube 26. When the expanded paraffin wax expands to a large volume, the extrusion force on the agitator 205 is large. At this time, the first rotating shaft 203 experiences greater resistance. When the second rotating shaft 301 rotates, the first inclined surface 405 slides on the side wall of the slot 403, causing the locking block 404 to slide out of the slot 403. This ensures that the second rotating shaft 301 and the fan 302 can rotate normally, while the first rotating shaft 203 stops rotating, avoiding greater resistance to the flow of coolant and ensuring the normal circulation effect of coolant.

[0042] The telescopic mechanism includes a plurality of arrayed T-shaped guide rods 501 inserted into the end of the second ring 402, and the side wall of the T-shaped guide rod 501 is provided with a plane 502. One end of the T-shaped guide rod 501 is fixed to the side wall of the locking block 404, and a first spring 503 is sleeved on the side wall of the T-shaped guide rod 501, which guides and resets the movement of the locking block 404.

[0043] The resistance mechanism includes a sleeve 601 fixedly inserted into the top of the hollow tube 16, and a sleeve rod 602 connected to the bottom of the sleeve 601 through a compression mechanism. A resistance block 603 is fixedly connected to the lower end of the sleeve rod 602, and the resistance block 603 includes a second inclined surface 604. When the expanded paraffin in the storage tube 26 is heated and expands, it pushes the moving disk 27 and the sliding rod 28 to move. When the thrust is greater than the resistance of the resistance block 603 to the sliding rod 28, one end of the sliding rod 28 slides on the second inclined surface 604 and pushes the resistance block 603 to move upward. The movement of the resistance block 603 drives the movement of the sleeve rod 602 and the second sliding disk 703, and causes the second sliding disk 703 to be compressed. The resistance block 603 can resist the movement of the sliding rod 28.

[0044] The compression mechanism includes a first sliding disk 701 slidably connected within the sleeve 601, and a second spring 702 fixedly connected to the bottom of the first sliding disk 701. The lower end of the second spring 702 is fixedly connected to a second sliding disk 703, which slides within the sleeve 601. The upper end of the sleeve rod 602 is fixed to the bottom of the second sliding disk 703. The movement of the first sliding disk 701 is driven by a pushing mechanism, which in turn adjusts the compression of the second spring 702, i.e., adjusts the squeezing force of the second spring 702 on the second sliding disk 703. This adjusts the resistance of the resistance block 603 to the sliding rod 28, thereby regulating and controlling the temperature of the coolant when switching between the first and second outlet pipes 102 and 103. This design offers greater applicability and better performance.

[0045] The pushing mechanism includes a first pushing rod 804 fixedly connected to the top of the second sliding plate 703, and a fixed tube 801 fixedly connected to the side wall of the temperature control valve body 1. A sealing cover 802 is threadedly connected to the side wall of the fixed tube 801, and a second pushing rod 803 is fixedly connected to the bottom of the sealing cover 802. An marking mechanism is provided on the side wall of the first liquid outlet pipe 102. By rotating the sealing cover 802, the sealing cover 802 drives the second pushing rod 803 to move downward, thereby pushing the first pushing rod 804 to move downward. The movement of the first pushing rod 804 drives the first sliding plate 701 to move downward.

[0046] The marking mechanism includes a marking plate 901 fixedly connected to the side wall of the first outlet pipe 102, and the surface of the marking plate 901 is provided with scale markings 902. The side wall of the sealing cover 802 is fixedly fitted with an indicator ring 903, which facilitates the control of the compression of the second spring 702, thereby adjusting the temperature of the coolant when switching between small and large circulation.

[0047] A temperature control method, utilizing a temperature control valve, includes the following steps:

[0048] S1: During use, the coolant after cooling the engine 10 enters the second outlet pipe 103 through the first pipe 12 and the inlet pipe 101. When the temperature of the engine 10 is low, the temperature of the coolant is also low. At this time, the expansion of the expanded paraffin in the storage pipe 26 is small. At this time, the moving plate 27 and the sliding rod 28 do not move. At this time, the sealing plate 20 seals the second outlet hole 18. The coolant returns to the engine 10 through the first through hole 30 and the first outlet hole 22, through the first outlet pipe 102 and the second pipe 15.

[0049] S2: When the engine 10 is at a high temperature, the circulating coolant is also at a high temperature. At this time, the expanded paraffin in the storage pipe 26 expands and pushes the moving disc 27 and the sliding rod 28 to move. The movement of the sliding rod 28 drives the connecting rod 29 to rotate, which in turn drives the connecting block 23 and the moving rod 19 to move downward. When the moving rod 19 moves downward, it drives the sealing plate 24 and the sealing disc 20 to move downward synchronously. At this time, the first through hole 30 and the first outlet hole 22 are misaligned, so that the sealing plate 24 can seal the first outlet hole 22. This allows the coolant to pass through the second outlet hole 18 and the second through hole 21, and then through the second outlet pipe 103 and the third pipe 13 into the radiator 11 for cooling. After cooling, the coolant is circulated back into the engine 10 through the fourth pipe 14. This process is repeated to control the temperature of the engine 10, ensuring its cooling effect while being more energy-efficient and environmentally friendly.

[0050] S3: When the coolant is circulating, when the coolant enters the inlet pipe 101, it impacts the surface of the fan 302 and causes it to rotate. The rotation of the fan 302 drives the rotation of the second shaft 301, which in turn drives the rotation of the second ring 402. Through the locking block 404, the first ring 401 is driven to rotate, which in turn drives the first shaft 203 and the rotating disk 204 to rotate. This causes the stirring rod 205 to stir the expanded paraffin in the storage tube 26, making its heat absorption and expansion more efficient and effective, thereby ensuring the accuracy of temperature control.

[0051] S4: When the expanded paraffin wax expands to a large volume, the extrusion force on the stirring rod 205 is large. At this time, the resistance of the first rotating shaft 203 is large. When the second rotating shaft 301 rotates, the first inclined surface 405 slides on the side wall of the slot 403 and the locking block 404 slides out of the slot 403. At the same time, the first spring 503 is compressed, which ensures that the second rotating shaft 301 and the fan 302 can rotate normally, while the first rotating shaft 203 no longer rotates, avoiding large resistance to the flow of coolant and ensuring the normal circulation effect of coolant.

[0052] S5: When the expanded paraffin wax in the storage tube 26 expands due to heat, it pushes the moving disk 27 and the sliding rod 28 to move. When the thrust is greater than the resistance of the resistance block 603 to the sliding rod 28, one end of the sliding rod 28 slides on the second inclined surface 604 and pushes the resistance block 603 to move upward. The movement of the resistance block 603 drives the movement of the sleeve rod 602 and the second sliding disk 703, causing the second sliding disk 703 to be compressed. The resistance block 603 can resist the movement of the sliding rod 28. Furthermore, by rotating the sealing cover 802... This causes the sealing cover 802 to move the second push rod 803 downward, which in turn pushes the first push rod 804 downward. The movement of the first push rod 804 causes the first sliding plate 701 to move downward, thereby adjusting the compression of the second spring 702, that is, adjusting the squeezing force of the second spring 702 on the second sliding plate 703, thereby adjusting the resistance of the resistance block 603 on the sliding rod 28, and thus regulating and controlling the temperature of the coolant when switching between the first outlet pipe 102 and the second outlet pipe 103. This makes it more applicable and has a better performance.

6. A temperature control method, utilizing a temperature control valve as described in any one of claims 1-5, characterized in that: Includes the following steps: S1: When in use, the coolant after cooling the engine (10) enters the second outlet pipe (103) through the first pipe (12) and the inlet pipe (101). When the temperature of the engine (10) is low, the temperature of the coolant is also low. At this time, the expansion amount of the expanded paraffin in the storage pipe (26) is small. At this time, the moving plate (27) and the sliding rod (28) do not move. At this time, the sealing plate (20) seals the second outlet hole (18). The coolant returns to the engine (10) through the first through hole (30) and the first outlet hole (22) via the first outlet pipe (102) and the second pipe (15). S2: When the engine (10) temperature is high, the circulating coolant temperature is also high. At this time, the expanded paraffin in the storage pipe (26) expands and pushes the moving disc (27) and sliding rod (28) to move. The movement of the sliding rod (28) drives the connecting rod (29) to rotate, which in turn drives the connecting block (23) and moving rod (19) to move downward. When the moving rod (19) moves downward, it drives the sealing plate (24) and sealing disc (20) to move downward synchronously. At this time, the first The through hole (30) is offset from the first liquid outlet hole (22), so that the sealing plate (24) can seal the first liquid outlet hole (22), so that the coolant passes through the second liquid outlet hole (18) and the second through hole (21) and then enters the radiator (11) through the second liquid outlet pipe (103) and the third pipe (13) for cooling. After cooling, the coolant is circulated back into the engine (10) through the fourth pipe (14). By repeating this process, the temperature of the engine (10) can be controlled. S3: When the coolant is circulating, when the coolant enters the inlet pipe (101), it impacts the surface of the fan (302) and causes it to rotate. The rotation of the fan (302) drives the rotation of the second shaft (301), the rotation of the second shaft (301) drives the rotation of the second ring (402), and drives the first ring (401) to rotate through the locking block (404), thereby driving the first shaft (203) and the rotating disk (204) to rotate, thereby causing the stirring rod (205) to stir the expanded paraffin in the storage tube (26); S4: When the expanded paraffin wax expands to a large volume, the extrusion force on the stirring rod (205) is large. At this time, the resistance of the first rotating shaft (203) is large. When the second rotating shaft (301) rotates, the first inclined surface (405) slides on the side wall of the slot (403) and the block (404) slides out of the slot (403). At the same time, the first spring (503) is compressed, which ensures that the second rotating shaft (301) and the fan (302) can rotate normally, while the first rotating shaft (203) no longer rotates, thus avoiding a large resistance to the flow of coolant. S5: When the expanded paraffin wax in the storage tube (26) expands due to heat, it pushes the moving disk (27) and the sliding rod (28) to move. When the thrust is greater than the resistance of the resistance block (603) to the sliding rod (28), one end of the sliding rod (28) slides on the second inclined plane (604) and pushes the resistance block (603) to move upward. The movement of the resistance block (603) drives the movement of the sleeve rod (602) and the second sliding disk (703), and causes the second sliding disk (703) to be compressed. The resistance block (603) can resist the movement of the sliding rod (28), and by rotating... The sealing cover (802) is rotated, causing the sealing cover (802) to drive the second push rod (803) to move downward, which in turn pushes the first push rod (804) to move downward. The movement of the first push rod (804) causes the first sliding plate (701) to move downward, thereby adjusting the compression of the second spring (702), that is, adjusting the squeezing force of the second spring (702) on the second sliding plate (703), thereby adjusting the resistance of the resistance block (603) on the sliding rod (28), and thus regulating and controlling the temperature of the coolant when switching between the first outlet pipe (102) and the second outlet pipe (103).
