Description

Technical Field

[0001] This utility model relates to the field of internal combustion engine technology, and in particular to an automatic high-temperature protection system for internal combustion engines. Background Technology

[0002] When implementing automatic high-temperature protection for internal combustion engines, a high-temperature automatic protection system is often used. This system is a device that automatically takes measures to protect the engine when the engine temperature is too high. It prevents engine damage due to overheating, extends engine life, avoids vehicle breakdowns and other unexpected situations caused by high-temperature malfunctions, and ensures driving safety and normal operation. This system is used because internal combustion engines can overheat during operation due to various reasons, and high temperatures can cause serious damage to the engine; therefore, this system is needed to provide timely protection.

[0003] The internal combustion engine high-temperature automatic protection system monitors the engine temperature. When the temperature exceeds the safety threshold, the system will automatically take measures to reduce the engine's power output or activate the cooling mechanism to prevent the engine from overheating and being damaged. Once the temperature returns to the normal range, the system will restore the engine to normal operating status.

[0004] Existing technologies for automatic high-temperature protection systems for internal combustion engines rely on traditional cooling systems that use natural convection or ordinary water pumps to drive coolant circulation. These systems have limited heat dissipation efficiency and, in high-temperature emergencies, cannot rapidly increase the coolant circulation speed and heat dissipation area, resulting in a slow coolant temperature drop. Consequently, they cannot effectively and promptly control the engine temperature within a safe range. Furthermore, existing systems lack precise, real-time monitoring and rapid response mechanisms for coolant temperature, failing to adjust cooling strategies in a timely manner based on the actual high-temperature conditions of the engine. This causes the engine to operate at high temperatures for extended periods, reducing both engine power performance and fuel economy. Therefore, an automatic high-temperature protection system for internal combustion engines is proposed to address these issues. Utility Model Content

This eliminates the need for complex tools and cumbersome operating procedures, significantly improving disassembly efficiency. At the same time, the limiting block restricts the sliding stroke, ensuring the safety and stability of the disassembly process and preventing damage to components due to excessive sliding. This simple, efficient, safe, and stable disassembly method reduces the workload and time costs for maintenance personnel, and also helps extend the service life of the radiator and cooling pipe, facilitating daily maintenance and repair of the equipment.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 3 to 5 An embodiment of this utility model provides a high-temperature automatic protection system for an internal combustion engine, including a radiator 1 for reducing the temperature of the engine coolant through heat exchange. A cooling fan 2 is fixedly connected to the right side of the radiator 1 for forcibly guiding air through the radiator fins 3 to enhance heat dissipation efficiency. Cooling fins 3 are fixedly connected to the left side of the radiator 1 to increase the outer surface area of ​​the radiator 1 and accelerate the transfer of heat to the air. A cooling protection mechanism is provided inside the radiator 1, and a quick-release mechanism is provided inside the radiator 1.

[0035] The cooling protection mechanism includes an expansion tank 4, which is used to contain the thermal expansion volume of the coolant and maintain the stable pressure of the cooling system. A connecting pipe 5 is fixedly connected to the bottom of the expansion tank 4, which is used to connect the expansion tank 4 to the main circuit of the cooling system to balance the pressure and flow. A pressure cover 6 is fixedly connected to the outside left side of the connecting pipe 5, which is used to seal the expansion tank 4 and adjust the system pressure to adapt to temperature changes. An adjustment component is set inside the pressure cover 6. When the temperature in the cooling system rises, the spring will deform due to heat and produce a corresponding change in elastic force.

[0036] A thermal expansion diaphragm 8 is fixedly connected to the bottom of the adjustment component. When the temperature in the cooling system changes, the diaphragm will expand or contract accordingly. A heat flow guide 9 is fixedly connected to the outside of the thermal expansion diaphragm 8. The heat flow guide 9 surrounds the outside of the thermal expansion diaphragm and can guide the heat flow in the cooling system to act evenly on the thermal expansion diaphragm, ensuring that the thermal expansion diaphragm can accurately sense the temperature change in the cooling system and avoid malfunctions caused by uneven heat flow distribution.

[0037] An actuator control rod 10 is fixedly connected to the bottom space of the thermal expansion diaphragm 8, which transmits the displacement of the thermal expansion diaphragm to the regulating valve. When the thermal expansion diaphragm expands or contracts due to temperature changes, it will drive the actuator control rod to move up and down, thereby controlling the regulating valve. A regulating valve 11 is fixedly connected to the outside of the actuator control rod 10. When the actuator control rod moves up and down, it will drive the valve core to move inside the regulating valve, thereby changing the opening of the regulating valve and regulating the flow of coolant. By controlling the flow of coolant, the cooling effect of the engine can be effectively regulated, and the function of automatic high temperature protection can be realized.

[0038] An auxiliary pressure relief chamber 12 is fixedly connected to the bottom space of the regulating valve 11. When the pressure in the cooling system is too high, the auxiliary pressure relief chamber can automatically open to release some pressure and prevent the cooling system from being damaged due to excessive pressure. The opening and closing of the auxiliary pressure relief chamber is controlled by the regulating valve. When the regulating valve detects abnormal pressure, it will trigger the auxiliary pressure relief chamber to work to ensure the safe operation of the cooling system. Multiple cooling pipes 13 are fixedly connected inside the radiator 1. When the coolant flows in the cooling pipes, it transfers heat to the heat sink through heat exchange with the heat sink, and then the heat sink dissipates the heat into the surrounding air. The bottom of the expansion tank 4 is fixedly connected to the top of the radiator 1.

[0039] The quick-release mechanism includes a handle 16, which is the operating component of the quick-release mechanism and is used to manually extract or fix the internal components of the radiator 1 to achieve quick disassembly or installation. The left and right sides of the radiator 1 are fixedly connected to slide rail 17, which is the guide component of the quick-release mechanism and provides a linear motion trajectory for the sliding block 20 and slide rail 21.

[0040] The slide rail 17 has a groove 18 in the internal space area, which is a groove structure inside the slide rail 17 to provide sliding space for the sliding block 20. The left and right sides of the inside of the groove 18 are fixedly connected to the limiting blocks 19. The limiting blocks are fixed structures inside the groove 18 to limit the travel range of the sliding block 20 and prevent excessive sliding. The bottom of the handle 16 is fixedly connected to the top left and right sides of the radiator 1, and the outside of the slide rail 17 is fixedly connected to the inside left and right sides of the radiator 1.

[0041] Reference Figures 1 to 2The adjustment assembly includes a thermal trigger spring 7, which is externally fixedly connected to the inside of the pressure cover 6. The top of the thermal expansion diaphragm 8 is fixedly connected to the bottom of the thermal trigger spring 7. A sliding block 20 is slidably connected in the space area inside the slide groove 18. The sliding block is the moving part of the quick release mechanism, driven by the handle 16, and slides along the slide groove 18, driving the slide rail 21 to move. The slide rail 21 is externally fixedly connected to the sliding block 20. The slide rail 21 is the secondary guide rail of the quick release mechanism and is connected to the sliding block 20 to guide the disassembly or installation of the cooling pipe 13.

[0042] A slide rail outlet 22 is provided on the outer left side of the slide groove 18. The slide rail outlet is the opening structure of the slide groove 18, which is used for the sliding block 20 and the slide rail 21 to enter and exit. The slide rail 21 is fixedly connected to the outer left and right sides of the cooling pipe 13. Multiple heat sinks 14 are fixedly connected inside the cooling pipe 13. When the coolant flows in the cooling pipe, the heat will be quickly transferred to the heat sink and then dissipated to the air outside the radiator through the heat sink, thereby cooling the coolant. A thermistor water temperature detector 15 is fixedly connected to the space area at the top of the cooling pipe 13, which can monitor the temperature of the coolant in real time.

[0043] Reference Figures 1 to 3 The radiator 1 has an outlet 23 fixedly connected to its front exterior, which is the interface for coolant to flow out of the radiator 1 and connects the engine body 25 and the water pump 26. A temperature sensor 24 is fixedly connected to the outside of the outlet 23 to monitor the coolant temperature at the outlet 23 in real time and provide data support for system control. The engine body 25 is fixedly connected to the right exterior of the outlet 23, which is the heat source of the cooling system. It generates high temperature through combustion and needs to rely on the cooling system to maintain normal temperature.

[0044] A water pump 26 is fixedly connected to the right side of the engine body 25. It is the circulating power source of the cooling system and drives the coolant to flow between the engine and the radiator. The outlet 23 is fixedly connected to the outside of the water pump 26. A water inlet 27 is fixedly connected to the left side of the engine body 25. It is the interface for the coolant to enter the engine body 25 and connects the radiator 1 and the water pump 26. The left side of the water inlet 27 is fixedly connected to the right side of the radiator 1, and the outside of the water inlet 27 is fixedly connected to the outside of the water pump 26.

[0045] Working principle: Radiator 1 reduces the engine coolant temperature through heat exchange. Cooling fan 2 forces air through the fins of radiator 1 to enhance heat dissipation. Cooling fins 3 increase the outer surface area to accelerate heat transfer. Coolant flows in cooling pipes 13 inside radiator 1, dissipating heat into the air through heat exchange with cooling fins 14 inside the cooling pipes 13. Thermistor water temperature detector 15 monitors the coolant temperature in real time. When the temperature in the cooling system rises, the thermal trigger spring 7 in the pressure cap 6 deforms due to heat, causing the thermal expansion diaphragm 8 to expand. The heat flow guide 9 guides the heat flow so that the thermal expansion diaphragm 8 accurately senses the temperature change. The thermal expansion diaphragm 8 drives the actuator control lever 10 to move up and down, which in turn drives the valve core of regulating valve 11 to move and change the opening, thereby regulating the coolant flow and adjusting the engine cooling effect. If the pressure in the cooling system is too high, regulating valve 11 triggers the auxiliary pressure relief chamber 12 to automatically open and release the pressure, ensuring the safety of the cooling system. At the same time, expansion tank 4 is connected to the main circuit of the cooling system through connecting pipe 5 to accommodate the thermal expansion volume of the coolant and maintain the stability of the cooling system pressure.

[0046] When it is necessary to disassemble the cooling pipe 13 inside the radiator 1, the operator manually grasps the handle 16 and pulls it upward. The handle 16 moves the top of the radiator 1 upward. At this time, since the slide rail 17 fixed on the left and right sides inside the radiator 1 remains stationary, while the slide rail 21 fixed on the left and right sides outside the cooling pipe 13 is slidably connected to the slide groove 18 of the slide rail 17 through the sliding block 20, under the action of the handle 16, the sliding block 20 will slide upward within the slide groove 18 along the travel range limited by the limiting block 19, thereby moving the slide rail 21 and the cooling pipe 13 upward together. When the sliding block 20 slides to the slide rail outlet 22 position, the sliding block 20, the slide rail 21 connected to it, and the cooling pipe 13 can be slid out of the slide rail 17 as a whole, thereby realizing the quick disassembly of the cooling pipe 13.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
