Description

Technical Field

[0001] This invention relates to the field of generator set technology, specifically to a compact, high-altitude, ultra-quiet generator set. Background Technology

[0002] As is well known, small silent generator sets, especially vehicle-mounted units, face a series of comprehensive technical challenges when used in special environments such as plateaus and mountains. Existing technologies generally have the following shortcomings: Severe power loss at high altitudes: Ordinary diesel engines experience a decrease in combustion efficiency and a significant reduction in output power at high altitudes due to the thin air (power decreases by about 8-12% for every 1000 meters increase in altitude). Existing solutions mostly rely on fixed-parameter boost compensation, lacking the ability to adaptively adjust based on real-time environmental parameters (such as air pressure, temperature, and humidity), resulting in insufficient compensation accuracy and slow response under varying operating conditions.

[0003] Quiet operation and heat dissipation efficiency are contradictory: Traditional silent enclosures, in order to achieve noise reduction, usually adopt a sealed or small-aperture design, which seriously hinders the flow of heat dissipation air. Under high load or high temperature environment, heat accumulates inside the unit, which can easily cause the main engine to overheat and shut down, reducing reliability. Conversely, if ventilation is increased to enhance heat dissipation, it will lead to a significant leakage of noise, which cannot meet the "ultra-quiet" requirement. Moreover, the large temperature difference between day and night in high-altitude areas can easily cause condensation to form inside the enclosure, further threatening electrical safety. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a compact, ultra-quiet high-altitude generator set, which has the advantages of automatically adapting to the complex high-altitude environment and simultaneously resolving multiple contradictions such as ultra-low noise, efficient heat dissipation, anti-condensation, and power compensation within an extremely compact space.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a compact, high-altitude, ultra-quiet generator set, comprising: The high-altitude intelligent power compensation system includes an intake pressure sensor and an electronic control unit, wherein the electronic control unit is configured to dynamically adjust the boost ratio of the turbocharger based on the intake pressure. A compact anti-condensation chassis, wherein the top of the compact anti-condensation chassis is integrated with an engine body, a generator body, a turbocharger intercooler and a radiator, and the turbocharger intercooler is mounted on top of the radiator; The multi-dimensional composite silent and heat dissipation synergistic structure includes a box frame and two independent air ducts set in the box frame. The two independent air ducts are an engine cooling air duct for cooling the engine body and a generator cooling air duct for cooling the generator body. The two air ducts are physically isolated within the box frame and have independent air inlets and outlets.

[0006] By adopting the above technical solution, the ambient air pressure changes are sensed by the intake pressure sensor, and the electronic control unit analyzes and calculates the required power compensation in real time. Then, the boost ratio of the turbocharger is dynamically adjusted to provide the engine with intake air of appropriate density, so as to achieve precise power recovery in high-altitude environments. The dual independent air ducts consisting of the engine cooling duct and the generator cooling duct work together with the adjustable silent louvers to ensure that the cooling of the engine and generator do not interfere with each other while ensuring extreme quietness. It can achieve engineering-grade ultra-low noise performance and continuous high-efficiency thermal management capabilities in an extremely compact space. In addition, the compact anti-condensation chassis and intelligent heating device work together to eliminate the risk of condensation from both structural and control perspectives. This makes the entire generator set suitable for space-constrained scenarios such as vehicles, and can also meet the reliable power supply needs of complex high-altitude environments.

[0007] The present invention is further configured such that: the engine cooling duct includes a first air outlet plate installed on the top rear side of the housing structure; a first low-speed fan is rotatably connected inside the first air outlet plate; an air guide shroud is fixedly connected to the front side of the first air outlet plate; a first guide plate is bolted to the bottom of the air guide shroud; the bottom of the first guide plate is bolted to a compact anti-condensation chassis; a first noise-absorbing grille is bolted inside the air guide shroud; and a second guide plate is bolted to the rear side of the left side of the inner wall of the housing structure, and the second guide plate is used in conjunction with the air guide shroud.

[0008] By adopting the above technical solution, cooling air enters from the rear left side of the housing and the rear area of ​​the bottom of the compact anti-condensation chassis through the setting of the engine cooling air duct. The air intake in the rear left side of the housing impacts the second guide plate, is guided and diffused, forming a preliminary uniform airflow. The air intake in the rear area of ​​the bottom of the compact anti-condensation chassis enters the air guide shroud through the first guide plate. The airflow is constrained by the guiding structure and flows through the radiator and the turbocharger intercooler located on top of it, fully absorbing its waste heat. Under the combined action of natural rise and negative pressure in front, the heated airflow enters the air guide shroud and passes through the first silencer grille. The noise energy is effectively absorbed and attenuated. Finally, the first low-speed fan located at the top of the rear side of the housing forces the silenced hot air out through the first air outlet plate, forming a complete and directional cooling cycle with air intake from the side and rear and air exhaust from the rear and top. Through the structured design of the engine cooling air duct, the targeted and efficient heat dissipation is enhanced, while also taking into account the quietness effect.

[0009] The present invention is further configured such that: the generator cooling duct includes a second air outlet plate, the second air outlet plate is installed on the front side of the left side of the housing frame, an air outlet duct is bolted to the right side of the second air outlet plate, and a second low-speed fan is bolted inside the air outlet duct; directional air ducts are bolted to the left side of the air outlet duct and the right side of the inner wall of the housing frame, and a second sound-absorbing grille is bolted inside the directional air duct.

[0010] By adopting the above technical solution, and by setting up a generator cooling duct, when the generator body is dissipating heat, cold air enters from an independent air inlet, is guided by a directional air duct, and directly blows onto the generator body windings to absorb the heat generated by the windings. The hot air is then discharged from the second air outlet plate through the air outlet duct by a second low-speed fan. The directional air duct limits the airflow direction, ensuring that the cold air is concentrated on the key parts of the generator body for heat dissipation, avoiding airflow dispersion. In addition, the second noise-absorbing grille is set inside the directional air duct to absorb the noise generated when the airflow passes through, preventing noise leakage from the air inlet and outlet. Through the design of the generator body's independent cooling duct, physical isolation from the engine body's heat dissipation is achieved, avoiding the decrease in heat dissipation efficiency caused by mutual interference of the hot air from both, and ensuring the stable winding temperature of the generator body when operating under high load.

[0011] The invention is further configured such that: the multi-dimensional composite silencing and heat dissipation synergistic structure also includes an adjustable silencing louver, the adjustable silencing louver being installed at the air inlet of the engine cooling duct and the generator cooling duct; the adjustable silencing louver includes a window frame, the window frame having several blades rotatably connected inside, and sound-absorbing sheets being adhered to the top and bottom of the blades; a shaft passing through the interior of each blade, and both ends of the shaft being bolted to the inner wall of the window frame; two lead screws rotatably connected to the bottom of the window frame, and threaded sleeves being threaded onto the surface of the lead screws; a support rod being bolted between the two threaded sleeves; an active connecting rod rotatably connected to the top of the support rod, and the top of the active connecting rod being rotatably connected to the bottom blade; and a driven connecting rod rotatably connected between two adjacent blades.

[0012] By adopting the above technical solution, adjustable silent louvers are installed at the air inlets of the two air ducts, and the opening and closing angle can be adjusted according to the operating conditions. During adjustment, the drive motor installed at the bottom of the lead screw drives the lead screw to rotate, which in turn moves the screw sleeve. The screw sleeve drives the support rod to move horizontally, and the support rod drives the bottom blades to rotate through the active connecting rod. Then, through the driven connecting rod, all blades are linked to open and close synchronously. When the airflow passes through the blades, the sound-absorbing plates at the top and bottom of the blades absorb noise as the airflow passes through. At the same time, the structural design of the blades reduces airflow disturbance and aerodynamic noise. The adjustable silent louvers achieve a dynamic balance between the silence and heat dissipation of the air inlet. The synchronous opening and closing design of the blades ensures convenient adjustment and uniform airflow. It can be flexibly adapted to different operating conditions. This design solves the problem that traditional fixed louvers cannot meet the needs of silence and heat dissipation under different operating conditions.

[0013] The present invention is further configured such that: the adjustable silent louver is electrically connected to the electronic control unit, and the electronic control unit controls the opening and closing angle of the adjustable silent louver according to the main load of the engine and the internal temperature of the housing structure.

[0014] By adopting the above technical solution, an electronic control unit is set as the central processor to continuously monitor load signals (such as current and power) that reflect the working intensity of the engine body, as well as temperature sensor data arranged at various key points in the housing. Based on the built-in intelligent algorithm model, the electronic control unit comprehensively evaluates the current heat dissipation requirements and the noise reduction target, and then drives the adjustment mechanism of the louvers to rotate the louver blades to an optimal angle. For example, the opening is reduced to prioritize noise reduction under low load and low temperature, and the opening is increased to prioritize heat dissipation under high load and high temperature.

[0015] The present invention is further configured such that: the box structure adopts a double-layer sandwich box structure, the box frame includes an outer metal layer, a middle filling layer and an inner structural layer, the outer metal layer is a high-strength metal skin, the inner structural layer is a perforated aluminum plate, and the middle filling layer is ceramic fiber cotton with sound absorption and heat insulation functions.

[0016] By adopting the above technical solution, the sound-absorbing properties of ceramic fiber cotton in the double-layer sandwich structure of the enclosure effectively absorb structural and aerodynamic noise inside the enclosure, improving the ultra-quiet effect. The heat insulation function reduces the temperature exchange between the inside and outside of the enclosure, alleviating the condensation problem caused by the large temperature difference between day and night at high altitudes. The combination of high-strength metal skin and perforated aluminum plate ensures both quiet operation and heat insulation while taking into account the structural strength and durability of the enclosure. This design solves the problem that traditional enclosures cannot simultaneously achieve quiet operation, heat insulation and structural strength, providing structural protection for the unit's ultra-quiet operation and anti-condensation.

[0017] The present invention is further configured such that: a cable compartment is provided inside the compact anti-condensation chassis, and a heating device consisting of an electronic control unit is provided in the condensation-prone area inside the cable compartment; the electronic control unit is also configured to monitor the temperature and humidity inside and outside the cable compartment, and to activate the heating device when it is determined that there is a risk of condensation.

[0018] By adopting the above technical solution, in the cable compartment where electrical connections are dense and humidity is extremely sensitive, the electronic control unit continuously monitors the ambient temperature and humidity through a deployed sensor network. The internal algorithm of the control unit calculates the current dew point temperature in the air in real time and compares it with the surface temperature of key parts such as cables and terminals (through sensor monitoring or model estimation). Once it is predicted that the surface temperature of an object in a certain area may drop below the dew point and there is a risk of condensation, the electronic control unit immediately and automatically activates the heating device in the corresponding area to provide precise and gentle heating, eliminating the conditions for condensation. This can ensure the absolute dryness and safety of the electrical system, and is suitable for environments with large diurnal temperature differences and drastic humidity changes, such as high altitudes. It greatly improves the operational reliability and safety of the unit under harsh climates and reduces maintenance costs and risks caused by electrical failures.

[0019] The invention is further configured such that: the heating device is a PTC constant temperature heating plate; the bottom of the cable compartment is provided with an inclined condensate guide channel and a collection channel; the end of the condensate guide channel is connected to the collection channel; and a waterproof and breathable valve is installed inside the collection channel.

[0020] The above technical solution uses an inclined condensate drainage channel to collect any trace amounts of condensate or moisture that may accidentally form. Gravity guides the condensate to a lower-positioned collection channel. The waterproof and breathable valve installed in the collection channel uses a special membrane material to allow air molecules to pass freely, thereby balancing the air pressure inside the cable compartment or box with the outside air and preventing negative or positive pressure caused by temperature changes. At the same time, the membrane material can effectively block the passage of liquid water, preventing the collected liquid from flowing back or external liquid from entering.

[0021] The present invention is further configured such that: the plateau intelligent power compensation system also includes an intake air temperature sensor and an atmospheric humidity sensor, and the electronic control unit is further configured to collect intake air pressure, temperature and humidity data in real time, calculate the current air density and theoretical power attenuation based on the data, and dynamically adjust the turbocharger boost ratio and the main engine fuel injection quantity to compensate for power.

[0022] By adopting the above technical solution, in addition to monitoring the intake air pressure, the system also monitors the intake air temperature and atmospheric humidity. The electronic control unit receives these three data points simultaneously and accurately calculates the actual density of the air entering the main cylinder of the engine through a built-in physical model (density is affected by pressure, temperature, and humidity). Based on a more realistic intake air density, the electronic control unit can more accurately assess the potential power loss of the main engine and issue more refined composite control commands accordingly. This not only adjusts the boost pressure of the turbocharger to "increase" the boost pressure, but may also adjust the fuel injection quantity and timing of the fuel injection system to "improve quality," thereby achieving global optimization of the air-fuel ratio.

[0023] The present invention is further configured such that: in the electronic control unit controlling silent heat dissipation, the heat dissipation demand is prioritized, and when the engine body temperature is lower than the first threshold, the adjustable silent louvers are controlled to reduce the opening degree to prioritize silence. When the temperature of the engine block and generator block exceeds the second threshold, the adjustable silent louvers are controlled to increase their opening and the fan speed is increased to prioritize heat dissipation.

[0024] Using the above technical solution, when the electronic control unit manages the louver opening and fan speed, the system continuously monitors the core temperature of the engine and generator bodies. When the temperature is within the ideal operating range that is both safe and efficient (below the first threshold), the control strategy tends to optimize the user experience by reducing the louver opening and maintaining a low fan speed to suppress the unit's operating noise to the lowest level. Once any heat source temperature is detected to rise and reach a higher warning threshold (second threshold), indicating that the heat dissipation demand has become urgent, the system will immediately switch to the "safety priority" mode, increase the louver opening and increase the fan speed to enhance heat dissipation with maximum ventilation until the temperature drops back to a safe range.

[0025] Compared with the prior art, the present invention provides a compact, ultra-quiet high-altitude generator set, which has the following advantages: This compact, ultra-quiet high-altitude generator set senses changes in ambient air pressure through an intake pressure sensor. The electronic control unit analyzes and calculates the required power compensation in real time, and then dynamically adjusts the turbocharger's boost ratio to provide the engine with intake air of appropriate density, thus achieving precise power recovery in high-altitude environments. The dual independent air ducts, consisting of engine and generator cooling ducts, work in conjunction with adjustable silent louvers to ensure extreme quietness while preventing interference between the cooling of the engine and generator. This achieves both engineering-grade ultra-low noise performance and continuous high-efficiency thermal management within an extremely compact space. In addition, the compact anti-condensation chassis and intelligent heating device work together to eliminate the risk of condensation from both structural and control perspectives. This makes the entire generator set suitable for space-constrained scenarios such as vehicles, as well as meeting the reliable power supply needs of complex high-altitude environments.

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.

[0029] Please see Figure 1-8 Compact, high-altitude ultra-quiet generator sets, including: The high-altitude intelligent power compensation system includes an intake pressure sensor and an electronic control unit. The electronic control unit is configured to dynamically adjust the boost ratio of the turbocharger based on the intake pressure. The compact anti-condensation chassis 1 has an integrated engine body 2, generator body 3, turbocharger intercooler 4 and radiator 5 mounted on its top. The turbocharger intercooler 4 is mounted on top of the radiator 5. The multi-dimensional composite noise reduction and heat dissipation synergistic structure includes a housing frame 6 and dual independent air ducts set within the housing frame 6. The dual independent air ducts are an engine cooling duct 7 for cooling the engine block 2 and a generator cooling duct 8 for cooling the generator block 3. The two air ducts are physically isolated within the housing frame 6 and have independent air inlets and outlets. By sensing changes in ambient air pressure through an intake pressure sensor, the electronic control unit analyzes and calculates the required power compensation amount in real time, and then dynamically adjusts the turbocharger's boost ratio to provide the engine block 2 with intake air of appropriate density, thereby achieving power reduction in high-altitude environments. The precise restoration; through the dual independent air ducts consisting of engine cooling air duct 7 and generator cooling air duct 8, and the adjustable silent louvers 9, while ensuring ultimate quietness, it ensures that the heat dissipation of the engine body 2 and generator body 3 does not interfere with each other. It can achieve engineering-grade ultra-low noise performance and continuous and efficient thermal management capabilities in an extremely compact space. In addition, the compact anti-condensation chassis 1 and the intelligent heating device 11 work together to eliminate the risk of condensation from both structural and control perspectives. This makes the entire generator set suitable for space-constrained scenarios such as vehicles, and can also meet the reliable power supply needs of complex high-altitude environments.

[0030] The engine cooling duct 7 includes a first air outlet plate 71 installed on the top rear side of the housing frame 6. A first low-speed fan 72 is rotatably connected inside the first air outlet plate 71. A guide shroud 73 is fixedly connected to the front side of the first air outlet plate 71, and a first guide plate 74 is bolted to the bottom of the guide shroud 73. The bottom of the first guide plate 74 is bolted to the compact anti-condensation chassis 1. A first noise reduction grille 75 is bolted to the inside of the guide shroud 73. A second guide plate 76 is bolted to the rear side of the left side of the inner wall of the housing frame 6, and the second guide plate 76 works in conjunction with the guide shroud 73. By setting up the engine cooling duct 7, cooling air enters from the rear left side of the housing and the rear area of ​​the bottom of the compact anti-condensation chassis 1. The air intake in the rear left side of the housing impacts the second guide plate 76 and is guided. The airflow diffuses and forms a preliminary uniform airflow. The air intake in the rear area of ​​the bottom of the compact anti-condensation chassis 1 enters the air shroud 73 through the first guide plate 74. The airflow is constrained by the guide structure and flows through the radiator 5 and the turbocharger intercooler 4 located on top of it, fully absorbing its waste heat. The heated airflow enters the air shroud 73 and passes through the first noise reduction grille 75 under the combined action of natural rise and negative pressure in front. The noise energy in it is effectively absorbed and attenuated. Finally, the first low-speed fan 72 located at the top of the rear side of the housing forces the silenced hot air out through the first air outlet plate 71, forming a complete and directional cooling cycle with air intake from the side and rear and air outlet from the rear and top. Through the structured design of the engine cooling air duct 7, the targeted and efficient heat dissipation is enhanced, while also taking into account the quiet effect.

[0031] The generator cooling duct 8 includes a second air outlet plate 81, which is installed on the front left side of the housing frame 6. An air outlet duct 82 is bolted to the right side of the second air outlet plate 81, and a second low-speed fan 83 is bolted inside the air outlet duct 82. Directional air ducts 84 are bolted to the left side of the air outlet duct 82 and the right side of the inner wall of the housing frame 6. A second sound-absorbing grille 85 is bolted inside the directional air duct 84. By setting up the generator cooling duct 8, when the generator body 3 is dissipating heat, cool air enters from the independent air inlet, is guided by the directional air ducts 84, and directly blows onto the windings of the generator body 3, absorbing the heat generated by the windings. The hot air is discharged from the second air outlet plate 81 through the air outlet duct 82 by the second low-speed fan 83, while the directional air duct 84 limits the airflow direction to ensure that the cold air is concentrated on the key heat dissipation parts of the generator body 3 and avoids airflow dispersion. The second noise-absorbing grille 85 is set inside the directional air duct 84 to absorb the noise generated when the airflow passes through and prevent noise leakage from the air inlet and outlet. Through the design of the independent heat dissipation air duct of the generator body 3, physical isolation from the heat dissipation of the engine body 2 is achieved, avoiding the decrease in heat dissipation efficiency caused by mutual interference of the hot air of the two, and ensuring the stable winding temperature of the generator body 3 when operating under high load.

[0032] The multi-dimensional composite sound insulation and heat dissipation synergistic structure also includes adjustable sound-absorbing louvers 9. These louvers 9 are located at the air inlets of the engine cooling duct 7 and the generator cooling duct 8. Each adjustable sound-absorbing louver 9 includes a frame 91. Several blades 92 are rotatably connected inside the frame 91, and sound-absorbing sheets are adhered to the top and bottom of each blade 92. A shaft 93 rotatably passes through the interior of each blade 92, and both ends of the shaft 93 are bolted to the inner wall of the frame 91. Two threaded rods 94 are rotatably connected to the bottom of the frame 91, and threaded sleeves 95 are threaded onto the surface of each threaded rod 94. A support rod 96 is bolted between the two threaded sleeves 95. An active connecting rod 97 is rotatably connected to the top of the support rod 96, and the top of the active connecting rod 97 is rotatably connected to the bottom blade 92. A driven connecting rod 98 is rotatably connected between two adjacent blades 92. This adjustable sound-absorbing louver 9... The adjustable silent louver 9 is installed at the air inlet of the two air ducts, and the opening and closing angle can be adjusted according to the operating conditions. During adjustment, the drive motor installed at the bottom of the lead screw 94 drives the lead screw 94 to rotate, which drives the screw sleeve 95 to move. The screw sleeve 95 drives the support rod 96 to move horizontally. The support rod 96 drives the bottom blade 92 to rotate through the active connecting rod 97, and then drives all the blades 92 to open and close synchronously through the driven connecting rod 98. When the airflow passes through the blades 92, the sound-absorbing plates at the top and bottom of the blades 92 absorb noise when the airflow passes through. At the same time, the structural design of the blades 92 reduces airflow disturbance and aerodynamic noise. The adjustable silent louver 9 achieves a dynamic balance between the silence and heat dissipation of the air inlet. The synchronous opening and closing design of the blades 92 ensures convenient adjustment and uniform airflow. It can be flexibly adapted to different operating conditions. This design solves the problem that traditional fixed louvers cannot meet the needs of silence and heat dissipation under different operating conditions.

[0033] The adjustable silent louver 9 is electrically connected to the electronic control unit. The electronic control unit controls the opening and closing angle of the adjustable silent louver 9 according to the load of the engine body 2 and the internal temperature of the housing structure 6. By setting the electronic control unit as the central processor, it continuously monitors the load signal (such as current and power) reflecting the working intensity of the engine body 2 and the temperature sensor data arranged at various key points in the housing. Based on the built-in intelligent algorithm model, the electronic control unit comprehensively evaluates the current heat dissipation requirements and the silent target, and then drives the adjustment mechanism of the louver to rotate the louver blades 92 to an optimal angle, such as reducing the opening degree to prioritize silent operation under low load and low temperature, and increasing the opening degree to prioritize heat dissipation under high load and high temperature.

[0034] The enclosure structure 6 adopts a double-layer sandwich structure, consisting of an outer metal layer 61, a middle filling layer 62, and an inner structural layer 63. The outer metal layer 61 is a high-strength metal skin, the inner structural layer 63 is a perforated aluminum plate, and the middle filling layer 62 is ceramic fiber cotton with both sound absorption and heat insulation functions. In the double-layer sandwich structure of the enclosure structure 6, the sound absorption characteristics of the ceramic fiber cotton effectively absorb the structural noise and aerodynamic noise inside the enclosure, improving the ultra-quiet effect. The heat insulation function reduces the temperature exchange between the inside and outside of the enclosure, alleviating the condensation problem caused by the large temperature difference between day and night at high altitudes. The combination of high-strength metal skin and perforated aluminum plate ensures both quiet operation and heat insulation while also taking into account the structural strength and durability of the enclosure. This design solves the problem that traditional enclosures cannot simultaneously achieve quiet operation, heat insulation, and structural strength, providing structural protection for the unit's ultra-quiet operation and anti-condensation.

[0035] The compact anti-condensation chassis 1 houses a cable compartment 10. Within the cable compartment 10, areas prone to condensation are equipped with heating devices 11 controlled by an electronic control unit. The electronic control unit is also configured to monitor the temperature and humidity inside and outside the cable compartment 10, and activate the heating devices 11 when a condensation risk is detected. Within the densely connected and humidity-sensitive cable compartment 10, the electronic control unit continuously monitors the ambient temperature and humidity through a deployed sensor network. The internal algorithm calculates the dew point temperature in the air in real time and compares it with the surface temperature of critical components such as cables and terminals (monitored by sensors or estimated by models). Once it is predicted that the surface temperature of an object in a certain area may drop below the dew point, posing a condensation risk, the electronic control unit immediately and automatically activates the corresponding heating device 11 for precise and gentle heating, eliminating condensation conditions. This ensures absolute dryness and safety of the electrical system, making it suitable for environments with large diurnal temperature variations and drastic humidity changes, such as high-altitude areas. It significantly improves the reliability and safety of the unit under harsh weather conditions and reduces maintenance costs and risks caused by electrical faults.

[0036] The heating device 11 is a PTC constant temperature heating plate. The bottom of the cable compartment 10 is provided with an inclined condensate guide channel 12 and a collection channel 13. The end of the condensate guide channel 12 is connected to the collection channel 13. A waterproof and breathable valve 14 is installed inside the collection channel 13. The inclined condensate guide channel 12 is responsible for collecting any trace amounts of condensate or moisture that may be accidentally formed and guides it to the lower collection channel 13 by gravity. The waterproof and breathable valve 14 installed in the collection channel 13 uses its special membrane material to allow air molecules to pass freely, thereby balancing the air pressure inside the cable compartment 10 or the box and the outside, avoiding negative or positive pressure due to temperature changes. At the same time, the membrane material can effectively block the passage of liquid water and prevent the collected liquid from flowing back or the intrusion of external liquid.

[0037] The high-altitude intelligent power compensation system also includes an intake air temperature sensor and an atmospheric humidity sensor. The electronic control unit is further configured to collect intake air pressure, temperature, and humidity data in real time. Based on the data, it calculates the current air density and theoretical power reduction, and dynamically adjusts the turbocharger boost ratio and the fuel injection quantity of the engine block 2 to compensate for power. In addition to monitoring intake air pressure, the system also monitors intake air temperature and atmospheric humidity. The electronic control unit receives these three data points simultaneously and accurately calculates the actual density of the air entering the cylinder of the engine block 2 through a built-in physical model (density is affected by pressure, temperature, and humidity). Based on a more realistic intake air density, the electronic control unit can more accurately assess the potential power loss of the engine block 2 and issue more refined composite control commands accordingly. It not only adjusts the turbocharger boost pressure to "increase" the boost pressure, but may also adjust the fuel injection quantity and timing of the fuel injection system to "improve quality," thereby achieving global optimization of the air-fuel ratio.

[0038] Among them, in the electronic control unit's control of silent heat dissipation, the heat dissipation needs are given priority. When the temperature of the engine body 2 is lower than the first threshold, the adjustable silent louver 9 is controlled to reduce the opening degree to prioritize silence. When the temperature of the engine body 2 and generator body 3 exceeds the second threshold, the adjustable silent louvers 9 are controlled to increase their opening and fan speed to prioritize heat dissipation. While the electronic control unit manages the louver opening and fan speed, the system continuously monitors the core temperature of the engine body 2 and generator body 3. When the temperature is within the ideal operating range that is both safe and efficient (below the first threshold), the control strategy tends to optimize the user experience by reducing the louver opening and maintaining a lower fan speed to suppress the unit's operating noise to the lowest level. Once the temperature of any heat source is detected to rise and reach a higher warning threshold (the second threshold), indicating that the heat dissipation demand has become urgent, the system will immediately switch to the "safety priority" mode, increasing the louver opening and fan speed to enhance heat dissipation with maximum ventilation until the temperature drops back to a safe range.

[0039] The working principle of this embodiment is as follows: After the generator set is installed, the electronic control unit initializes and simultaneously activates the intake pressure, temperature, and atmospheric humidity sensors, as well as the temperature and humidity sensors inside the housing and cable compartment 10. This collects environmental and equipment data in real time, laying the foundation for subsequent adjustments. Based on the collected data, the electronic control unit calculates the air density and theoretical power reduction, dynamically adjusting the turbocharger boost ratio and coordinating with the turbocharger intercooler 4 for cooling. Simultaneously, it optimizes the fuel injection quantity of the engine block 2 to ensure complete combustion and precise power recovery in high-altitude environments. Furthermore, the electronic control unit controls the opening angle of the adjustable silent louvers 9 based on the load on the engine block 2 and the housing temperature. Under low load and low temperature conditions, the louvers reduce their opening angle to prioritize noise reduction. Under high load and high temperature, the opening is increased and the speed of the dual low-speed fans is increased to prioritize heat dissipation. Moreover, the engine cooling duct 7 and the generator cooling duct 8 operate independently. Cold air flows precisely through the heat dissipation components via the guide structure, absorbs heat, and is then discharged after noise reduction through the silencer grille, avoiding heat backflow and noise leakage. During unit operation, the electronic control unit monitors the temperature and humidity of the cable compartment 10 in real time, calculates the dew point temperature, and activates the PTC constant temperature heating plate for precise heating when it is determined that there is a risk of condensation. A small amount of condensate flows into the collection tank 13 through the guide channel and is discharged through the waterproof vent valve 14, while balancing the internal and external air pressure. During unit operation, the electronic control unit continuously and dynamically fine-tunes various parameters to maintain the optimal balance between power, quietness, heat dissipation, and anti-condensation.
