Description

Technical Field

[0001] This invention relates to the field of engine cooling technology, specifically to an integrated air-water cooling engine cooling system. Background Technology

[0002] As engine technology continues to develop towards higher power density and miniaturization, the performance requirements of its cooling system are increasing. Traditional single air-cooling or water-cooling methods are gradually showing their limitations in dealing with high heat loads and complex operating conditions. Air-cooling has a simple structure but limited heat dissipation efficiency and is easily affected by ambient temperature. Water-cooling has a stable heat dissipation effect but requires additional water pumps and independent circulation pipelines, which increases system complexity and cost. Therefore, how to organically combine air-cooling and water-cooling and achieve a high degree of structural integration, and make full use of the engine's own power to drive heat dissipation, has become an important research direction in the design of current engine cooling systems.

[0003] Patent CN217681969U discloses an integrated water-cooled intercooler and engine, belonging to the field of cooling system technology. The integrated water-cooled intercooler includes a heat dissipation core, one end of which is connected to the exhaust chamber, and the other end is connected in parallel to the EGR intake chamber and the intercooler intake chamber. The heat dissipation core includes a shell with a cooling cavity and an air passage and a liquid passage located in the cooling cavity. The EGR intake chamber and the intercooler intake chamber are connected to the air passage. The integrated water-cooled intercooler also includes an inlet pipe and an outlet pipe connected to the liquid passage. By connecting one end of the heat dissipation core to the exhaust chamber and the other end to the EGR intake chamber and the intercooler intake chamber in parallel, the risk of leakage at the seals caused by the need to seal the interfaces of multiple pipes is reduced, improving the sealing performance and operational stability of the entire cooling system. Moreover, one intercooler can cool two gas pipes, achieving functional integration and reducing the space occupied, thus making engine miniaturization possible. However, this patent has the problem of low efficiency due to relying on only one cooling method. Therefore, an integrated air-water cooling engine heat dissipation system is proposed to solve the above-mentioned problems. Summary of the Invention

[0008] According to the above technical solution, the inner sidewall of the impeller extension ring is provided with a convex strip, four arc-shaped magnetic strips are provided, and the four arc-shaped magnetic strips are distributed equidistantly around the center of the inner groove ring, and four repulsive magnetic blocks are provided.

[0011] According to the above technical solution, the water-cooled circulation structure includes a cooling water tank.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: This integrated air-water cooled engine cooling system utilizes the engine's own rotational power to simultaneously achieve three major functions: automatic vibration cleaning of the filter, air-cooled auxiliary cooling of the cylinder block, and forced circulation cooling of the coolant. All three functions share the same drive source, eliminating the need for additional motors or control units. The system is highly integrated and energy-efficient. Vibration cleaning ensures smooth air intake and stable dynamic balance of the blower impeller. Air-cooled auxiliary cooling distributes airflow evenly across the outer surface of the cylinder block to reduce heat load. The water-cooled circulation removes internal heat through the flow of liquid within the cylinder block sidewall cavity and uses the airflow from the blower impeller to cool the coolant. The three functions work together to form a complete cooling system from intake filtration and external air cooling to internal liquid cooling. While maintaining a compact structure and operational reliability, this system significantly improves the engine's cooling efficiency and long-term operational stability.

[0014] This integrated air-water cooled engine cooling system uses vibration to prevent dust from clogging the filter and affecting airflow. The advantage of this design is that the engine's own rotational power can achieve automatic intermittent vibration cleaning of the filter, eliminating the need for an additional motor or control unit. This results in a compact and highly reliable structure. At the same time, the periodic vibration can promptly remove dust adhering to the filter surface, maintaining unobstructed airflow, thereby extending the filter's maintenance cycle and ensuring the engine's air intake stability. It also prevents excessive dust accumulation on the blower impeller, which can cause rotational imbalance and vibration, thus avoiding problems such as uneven bearing wear, increased vibration, and increased rotational resistance caused by rotational imbalance.

[0015] This integrated air-water cooling engine cooling system synchronously drives the transverse impeller through gear transmission, achieving auxiliary cooling of the cylinder block without the need for additional independent drive components. It features a compact structure and high transmission efficiency. At the same time, the side grilles guide airflow to the grooves on the outer surface of the cylinder block, making the airflow distribution more uniform and effectively improving the cooling effect of the cylinder block. This helps to reduce the thermal load of the engine body during operation and ensures long-term operational stability.

[0016] This integrated air-water cooling engine heat dissipation system achieves liquid circulation by synchronously driving a peristaltic disc through a linkage shaft. It can complete the forced flow of coolant without the need for an additional water pump. At the same time, it uses the airflow generated by the blower impeller to cool the coolant tank, forming a self-sufficient liquid cooling circulation system. The system is highly integrated and has low energy consumption. The liquid flowing in the cylinder block side wall cavity can effectively absorb the heat generated by the engine body. After being cooled by the coolant tank, it is circulated for reuse, thereby achieving a continuous and stable cooling effect and significantly improving the heat dissipation efficiency and operational reliability of the engine body.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 One embodiment of the present invention is: an integrated air-water cooling engine heat dissipation system, including an engine body 1, a muffler 2, an oil tank 3, a cylinder block 4, and an air-cooling drive structure 5 for promoting the flow of surrounding air installed on the side of the engine body 1. A cooling auxiliary structure 6 for assisting the cooling of the cylinder block 4 is installed at the rear of the engine body 1. A water-cooled circulation structure 7 is provided on the side of the heat dissipation auxiliary structure 6 away from the air-cooled drive structure 5 to remove heat from the inside of the cylinder body 4 through liquid flow. The air-cooled drive structure 5 includes a blower end shell 501, inside which a blower impeller 502 is disposed. A drive shaft 503 is fixedly connected to the shaft center of the blower impeller 502. An impeller extension ring 504 is fixedly connected to the side of the blower impeller 502 away from the engine body 1. An inner groove ring 505 is slidably connected to the impeller extension ring 504. A filter screen 506 is fixedly connected to the inner wall of the inner groove ring 505. Multiple arc-shaped magnetic strips 507 are fixedly connected to the edge side of the inner groove ring 505. A positioning ring 508 is fixedly connected to the outer surface of the blower end shell 501. A repulsive magnetic block 512 is embedded on the side of the positioning ring 508 near the inner groove ring 505.

[0021] Two cylinder blocks 4 are located on the top of the engine body 1, an oil tank 3 is installed on the upper left of the engine body 1, and a muffler 2 is installed on the front of the engine body 1.

[0022] The air-cooled drive structure 5 also includes an impeller toothed disk 511, which is fixedly connected to the outer ring surface of the blower impeller 502 on the side close to the engine body 1.

[0023] The inner wall of the impeller extension ring 504 is provided with raised ribs, and four arc-shaped magnetic strips 507 are provided, which are equidistantly distributed around the center of the inner groove ring 505. Four repulsive magnetic blocks 512 are provided. When the engine body 1 is in the working state, the rotation of the engine body 1 drives the drive shaft 503 to rotate, causing the blower impeller 502 connected to the drive shaft 503 to rotate together. The rotation of the blower impeller 502 drives the connected impeller extension ring 504 and the blower end shell 501 to rotate together. During rotation, the impeller extension ring 504 drives the connected inner groove ring 505 to rotate synchronously via the inner protrusion. During rotation, when the connected arc-shaped magnetic strip 507 aligns vertically with the repulsive magnetic block 512 fixed to the positioning ring 508, the inner groove ring 505, under the action of magnetic repulsion, will move the filter screen 506 away from the spring plate 509 and vibrator block 510 fixed to the positioning ring 508 along the inner wall of the impeller extension ring 504. When the arc-shaped magnetic strip 507 and the repulsive magnetic block 512 are misaligned... When the engine is turned on, the magnetic attraction of the arc-shaped magnetic strip 507 causes the inner groove ring 505 to slide close to the iron positioning ring 508, thereby causing the blower impeller 502 to drive the inner groove ring 505 to rotate periodically and slide with the impeller extension ring 504 to form vibration, thus preventing the filter screen 506 from being clogged by dust and affecting the air intake. The advantage of this setting is that the automatic intermittent vibration cleaning of the filter screen 506 can be achieved by using the rotational power of the engine itself, without the need for an additional motor or control unit. The structure is compact and highly reliable. At the same time, the periodic vibration can make the dust attached to the surface of the filter screen 506 fall off in time, keeping the air intake unobstructed, thereby extending the maintenance cycle of the filter screen 506 and ensuring the intake stability of the engine body 1. It also prevents the blower impeller 502 from being unbalanced due to excessive dust, which would cause shaking and thus avoid problems such as bearing wear, increased vibration and increased rotational resistance caused by rotational imbalance.

[0024] The heat dissipation auxiliary structure 6 includes an air guide end shell 601, a linkage shaft 605 is rotatably connected inside the air guide end shell 601, a transverse impeller 602 is fixedly connected to the outer surface of the linkage shaft 605, a transmission gear 604 is fixedly connected to one end of the linkage shaft 605, a middle gear 603 is meshed with the side of the impeller gear disk 511, an impeller disk 606 is fixedly connected to the side of the transverse impeller 602, an airflow cavity 607 is provided inside the air guide end shell 601, and a side grille groove 608 is opened on the front side of the air guide end shell 601.

[0025] The intermediate gear 603 meshes with the transmission gear 604. The air guide end shell 601 is fixedly connected to the side of the blower end shell 501. A partition plate is provided on the outer side of the impeller disk 606, and the partition plate is fixedly connected to the inner wall of the air guide end shell 601. The airflow cavity 607 is located between the partition plate and the blower end shell 501. The outer surface of the cylinder body 4 matches the outer shape of the air guide end shell 601. When the blower impeller 502 rotates, the blower impeller 502 drives the connected impeller gear disk 511 to rotate together. The impeller gear disk 511 drives the transmission gear 604 through the meshing intermediate gear 603. The transmission gear 604 drives the transverse impeller 602 to rotate through the linkage shaft 605. When the linkage shaft 605 rotates, it drives the transverse impeller 602 to rotate. When the impeller 602 is in operation, outside air enters the air guide shell 601 and is blown outwards through the side grille 608 on the rear side of the airflow cavity 607 inside the air guide shell 601. The airflow blown out from the side grille 608 passes through the groove on the outer surface of the cylinder block 4 to assist in heat dissipation. The transverse impeller 602 is synchronously driven by gear transmission. It can achieve auxiliary heat dissipation of the cylinder block 4 without the need to add an independent drive component. The structure is compact and has high transmission efficiency. At the same time, the side grille 608 guides the airflow to the groove on the outer surface of the cylinder block 4, making the heat dissipation airflow distribution more uniform and effectively improving the heat dissipation effect of the cylinder block 4. This helps to reduce the thermal load of the engine body 1 during operation and ensures the stability of long-term operation.

[0026] The water-cooled circulation structure 7 includes a cooling water tank 701. Multiple exhaust slots 702 are provided on the front side of the cooling water tank 701. An input port 703 and an output port 704 are fixedly connected to the side of the cooling water tank 701. An input pipe 705 is fixedly connected to the end of the input port 703 away from the cooling water tank 701. An output pipe 706 is fixedly connected to the end of the output port 704 away from the cooling water tank 701. A flexible hose 707 is fixedly connected to the end of the output pipe 706 away from the output port 704. A peristaltic disc 708 is provided on the inner side of the flexible hose 707. A peristaltic wheel 709 is rotatably connected to the side of the peristaltic disc 708. A storage water tank 710 is fixedly connected to the bottom of the oil tank 3. A water injection pipe 711 is fixedly connected to the top of the storage water tank 710. A drain pipe 712 is fixedly connected to the bottom surface of the air guide end shell 601. A communication port 713 is provided on the side of the cylinder body 4.

[0027] The cylinder body 4 has a side wall cavity inside. Two connecting ports 713 are provided on the sides of both cylinder bodies 4, and the two cylinder bodies 4 are interconnected. The cylinder bodies 4 are connected to the input pipe 705 through the side wall cavity. The exhaust duct 702 is connected to the inside of the blower end shell 501. The top end of the drain pipe 712 is connected to the flexible hose 707, and the bottom end of the drain pipe 712 is connected to the water storage tank 710. When the transverse impeller 602 rotates, the transverse impeller 602... The linkage shaft 605 drives the peristaltic disc 708 to rotate synchronously. When the peristaltic disc 708 rotates, it squeezes the hose 707 through the peristaltic wheel 709, causing the hose 707 to deform under pressure and create a negative pressure inside the hose, which drives the liquid in the connected output pipe 706 to flow. The hose 707 then transports the water to the storage tank 710 through the drain pipe 712. The storage tank 710 introduces water into the cavity on the side wall of the cylinder body 4 through the connecting port 713. After the liquid flows through the cavity on the side wall of the cylinder body 4 and carries away the heat, The coolant is discharged from the input pipe 705 connected to the inside of the engine block 1 and enters the coolant tank 701 through the input port 703. The coolant tank 701 generates airflow through the blower impeller 502 and blows it out from the exhaust duct 702, which reduces the temperature of the liquid entering the coolant tank 701. The cooled water then flows back to the storage tank 710 through the output pipe 706 and hose 707 connected to the output port 704. The liquid circulation is achieved by synchronously driving the peristaltic disc 708 through the linkage shaft 605. The forced flow of coolant can be completed without the need for an additional water pump. At the same time, the airflow generated by the blower impeller 502 is used to cool the coolant tank 701, forming a self-sufficient liquid cooling circulation system. The structure is highly integrated and has low energy consumption. The liquid flowing in the cavity of the side wall of the cylinder block 4 can effectively absorb the heat generated by the engine block 1. After being cooled by the coolant tank 701, it is recycled, thereby achieving a continuous and stable cooling effect and significantly improving the heat dissipation efficiency and operational reliability of the engine block 1.

[0028] Working principle: When the engine body 1 is in operation, the rotation of the engine body 1 drives the drive shaft 503 to rotate, causing the blower impeller 502 connected to the drive shaft 503 to rotate together. The rotation of the blower impeller 502 drives the connected impeller extension ring 504 to rotate relative to the blower end shell 501. The impeller extension ring 504 drives the connected inner groove ring 505 to rotate synchronously through the inner protrusion. During the rotation of the inner groove ring 505, when the connected arc-shaped magnetic strip 507 aligns vertically with the repulsive magnetic block 512 fixed by the positioning ring 508, Under the magnetic repulsion, the inner groove ring 505 will move the filter screen 506 away from the spring plate 509 and the vibrating block 510 fixed by the positioning ring 508 along the inner wall of the impeller extension ring 504. When the arc-shaped magnetic strip 507 and the repulsive magnetic block 512 are misaligned, the magnetic attraction of the arc-shaped magnetic strip 507 will cause the inner groove ring 505 to slide close to the iron positioning ring 508, so that the blower impeller 502 will drive the inner groove ring 505 to rotate periodically and slide with the impeller extension ring 504 to form vibration, thus preventing the filter screen 506 from being blocked by dust and affecting the air intake. When the blower impeller 502 rotates, it drives the connected impeller tooth disk 511 to rotate together. The impeller tooth disk 511 drives the transmission gear 604 through the meshing middle gear 603. The transmission gear 604 drives the transverse impeller 602 to rotate through the linkage shaft 605. When the linkage shaft 605 rotates, it drives the transverse impeller 602 to work, allowing outside air to enter the air guide end shell 601 and be blown out and diffused outward through the side grid groove 608 on the rear side of the airflow cavity 607 in the air guide end shell 601. The airflow blown out from the side grid groove 608 will pass through the groove on the outer surface of the cylinder body 4 to assist in heat dissipation. When the transverse impeller 602 rotates, it drives the peristaltic disc 708 to rotate synchronously via the connected linkage rod 605. As the peristaltic disc 708 rotates, it squeezes the hose 707 via the peristaltic wheel 709, causing the hose 707 to deform under pressure and creating a negative pressure inside, which in turn drives the liquid flow in the connected output pipe 706. The hose 707 then delivers water to the storage tank 710 through the drain pipe 712. The storage tank 710 then guides water into the side wall of the cylinder body 4 through the connecting port 713. Inside the cavity, the liquid flows through the side wall cavity of the cylinder block 4 and carries away the heat. It is then discharged from the input pipe 705 connected to the inside of the engine body 1 and enters the coolant tank 701 through the input port 703. The coolant tank 701 generates airflow through the blower impeller 502 and blows it out from the exhaust duct 702, which lowers the temperature of the liquid entering the coolant tank 701. The cooled water then flows back to the storage tank 710 through the output pipe 706 and the hose 707 connected to the output port 704.
