[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a hydraulic power station heat dissipation structure, including: a chassis 10, and a hydraulic oil tank 20 disposed at the bottom of the chassis 10. A power output component 30 is also disposed on the chassis 10. The power output component 30 includes an engine 32, a hydraulic pump 34 coaxially connected to the output end of the engine 32, and a cooling fan 36. A first radiator 40 is connected to the hydraulic passage formed between the hydraulic oil tank 20 and the hydraulic pump 34. The air outlet of the cooling fan 36 faces the first radiator 40 and is used to dissipate heat from the first radiator 40. A guide shroud 50 corresponding to the air inlet 322 of the engine 32 is disposed on the front side of the chassis 10 to transmit the intake airflow through the built-in fan in the engine 32 to the heat dissipation groove 60 on the rear side of the chassis 10.

[0028] Specifically, the power output assembly 30 includes an engine 32, which is the power source of the hydraulic power station. Its output end is coaxially connected to a hydraulic pump 34 and a cooling fan 36. This coaxial connection ensures efficient power transmission, allowing the hydraulic pump 34 to convert the mechanical energy of the engine 32 into hydraulic energy, providing power to the hydraulic system. Simultaneously, the cooling fan 36 operates synchronously with the engine 32. A first radiator 40 is connected to the hydraulic passage formed between the hydraulic oil tank 20 and the hydraulic pump 34. The first radiator 40 cools the hydraulic oil, preventing performance degradation due to overheating. The air outlet of the cooling fan 36 faces the first radiator 40. When the cooling fan 36 operates, it generates airflow, providing forced convection cooling to the first radiator 40, accelerating its cooling speed and effectively reducing the temperature of the hydraulic oil. Furthermore, a deflector 50 corresponding to the air inlet 322 of the engine 32 is provided on the front side of the chassis 10. The deflector 50 guides outside air into the engine 32. The intake airflow is delivered to the heat dissipation slot 60 at the rear of the chassis 10 by the built-in fan in the engine 32, thereby achieving heat dissipation of the engine 32 and ensuring that the engine 32 operates within a suitable temperature range.

[0029] The hydraulic power station cooling structure provided in this embodiment uses a cooling fan 36 coaxially connected to the engine 32, allowing the cooling fan 36 to operate synchronously according to the engine 32's operating status. This eliminates the need for an additional drive unit, simplifying the structure and reducing costs. Simultaneously, the cooling fan 36 provides targeted cooling to the first radiator 40, quickly and effectively reducing the hydraulic oil temperature, ensuring the stability and reliability of the hydraulic system, preventing system failures due to hydraulic oil overheating, and enabling the mobile hydraulic power station to operate at full load for extended periods. Furthermore, the cooperation between the air guide 50 and the engine 32's air inlet 322, along with the heat dissipation groove 60, forms a complete cooling channel for the engine 32, effectively dissipating the heat generated by the engine 32, preventing overheating, and improving the engine 32's working efficiency and service life. This design allows for separate cooling of the engine 32 and hydraulic oil, improving the cooling effect of the hydraulic power station and enhancing its environmental adaptability and operational stability.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a fuel tank 70 and a flow guide cavity 80 are provided on opposite sides of the chassis 10 in the width direction. The fuel tank 70 and the flow guide cavity 80 are respectively connected to the bottom plate 12 of the chassis 10. The bottom plate 12 is provided on opposite sides in the width direction with a first air inlet 122 corresponding to the flow guide cavity 80. A second air inlet 124 is provided on the front side of the bottom plate 12. A gap 90 is formed between the engine 32 and the hydraulic oil tank 20. One airflow can flow from the second air inlet 124 along the gap 90 to the cooling fan 36, and another airflow can flow from the first air inlet 122 along the flow guide cavity 80 to the cooling fan 36.

[0031] Specifically, a fuel tank 70 and a flow guide cavity 80 are arranged on opposite sides of the chassis 10 in the width direction. The fuel tank 70 stores fuel to provide fuel for the engine 32; the flow guide cavity 80 guides airflow during heat dissipation. Simultaneously, this structure serves as the outer shell of the entire hydraulic power station, improving space utilization and blocking sound transmission. Furthermore, the design of multiple air inlets and airflow channels guides more outside air into the cooling fan 36, forming multiple airflows to cool the first radiator 40. The increased airflow enhances convective heat dissipation, allowing the first radiator 40 to dissipate heat more quickly, further reducing the temperature of the hydraulic oil. In addition, the aforementioned gap 90 ensures that all components of the hydraulic power station receive good heat dissipation under different operating conditions, improving the overall heat dissipation effect and stability of the equipment, extending its service life, and enabling the hydraulic power station to better adapt to various complex working environments, solving the problem of poor environmental adaptability caused by heat dissipation issues.

[0032] like Figure 1 and Figure 2 As shown, the fairing 50 is provided with an array of air holes 52, and the chassis 10 is also provided with a guide plate 54 that matches the fairing 50. An isolation cavity is formed between the guide plate 54 and the fairing 50. The air inlet 322 of the engine 32 is connected to the isolation cavity, and the isolation cavity is isolated from the gap 90.

[0033] Specifically, the air deflector 50 is arrayed with air vents 52, which allow outside air to enter the isolation chamber through the air deflector 50. The chassis 10 also has a guide plate 54 that mates with the air deflector 50, forming an isolation chamber between the guide plate 54 and the air deflector 50. This isolation chamber isolates and guides airflow. The air inlet 322 of the engine 32 communicates with the isolation chamber, which is isolated from the gap 90. This design ensures that the air entering the engine 32 is filtered and guided by the isolation chamber, making the air entering the engine 32 more uniform and stable. It avoids interference from airflow entering from other channels, ensuring the quality and stability of the engine 32's air intake. Furthermore, the isolation chamber from the gap 90 ensures that the cooling paths for the engine 32 and the hydraulic oil do not interfere with each other, thus avoiding mutual influence and improving cooling efficiency.

[0034] like Figure 4 As shown, a second radiator 38 connected to the engine 32 is provided in the isolation chamber. The second radiator 38 is used to cool the engine oil in the engine 32. The second radiator 38 is arranged corresponding to the air inlet 322 of the engine 32.

[0035] Specifically, the second radiator 38 is configured corresponding to the air inlet 322 of the engine 32. When outside air enters the isolation chamber through the air vent 52 of the deflector 50, it passes through the second radiator 38 to dissipate heat, thereby reducing the temperature of the engine oil in the engine 32. Thus, the second radiator 38 provides a dedicated cooling path for the engine oil in the engine 32, effectively and promptly reducing the oil temperature, ensuring the lubrication performance and cooling effect of the oil, reducing friction and wear of internal parts of the engine 32, and improving the reliability and stability of the engine 32.

[0036] It should be noted that the first radiator 40 and the second radiator 38 can be finned radiators. The fins can contact the surrounding air, dissipating heat into the environment through forced convection (such as fan-driven) or natural convection (relying on air density differences) to achieve cooling.

[0037] like Figure 3 and Figure 5 As shown, the hydraulic oil tank 20 includes a shell 22, which is welded to the base plate 12 to form the hydraulic oil tank 20; the shell 22 is provided with an oil outlet 24 and an oil return port 26, the oil outlet 24 is connected to the hydraulic pump 34, and the oil return port 26 is connected to the first radiator 40.

[0038] Specifically, the housing 22 and the base plate 12 are welded together to form a hydraulic oil tank 20. This welding method ensures the sealing of the hydraulic oil tank 20 and prevents hydraulic oil leakage. The housing 22 is provided with an oil outlet 24 and an oil return port 26. The oil outlet 24 is connected to the hydraulic pump 34 and is used to transport the hydraulic oil in the hydraulic oil tank 20 to the hydraulic pump 34 to provide power to the hydraulic system. The oil return port 26 is connected to the first radiator 40. After the hydraulic system has been working, the hot oil is cooled by the first radiator 40 and then flows back to the hydraulic oil tank 20 through the oil return port 26, ensuring that the temperature of the hydraulic oil is always within a suitable range and maintaining the stability and working efficiency of the hydraulic system.

[0039] like Figure 5 and Figure 6 As shown, an L-shaped baffle 222 is provided inside the housing 22, and the orthographic projections of the oil outlet 24 and the oil return port 26 on the bottom plate 12 are located on opposite sides of the L-shaped baffle 222.

[0040] Specifically, the L-shaped baffle 222 separates the hydraulic oil in the hydraulic oil tank 20, allowing the hot oil flowing back from the return port 26 and the cold oil flowing out from the outlet port 24 to be relatively independent within the hydraulic oil tank 20. This avoids direct mixing of hot and cold oil and helps improve the heat dissipation of the hydraulic oil. Figure 6 As shown, the hot oil flowing back through the return port 26 will gradually flow to the outlet 24 in the direction indicated by the arrow. During the flow, the hydraulic oil will be further cooled. The separation method can make the hydraulic oil form a more reasonable flow path in the hydraulic oil tank 20, which helps to uniformly cool the hydraulic oil and ensure a stable supply. This ensures that the hydraulic system can continuously obtain hydraulic oil at a suitable temperature, and improves the working stability and reliability of the hydraulic system.

[0041] like Figure 1 As shown, the base plate 12 is provided with a first oil drain port 126 corresponding to the hydraulic oil tank 20, and a second oil drain port 128 corresponding to the fuel tank 70. The first oil drain port 126 can be connected to the hydraulic oil tank 20, and the second oil drain port 128 can be connected to their respective fuel tanks 70.

[0042] Specifically, the first drain port 126 and the second drain port 128 facilitate the maintenance and repair of the hydraulic oil tank 20 and the fuel tank 70. When equipment malfunctions or requires regular maintenance, hydraulic oil and fuel can be drained quickly and easily, reducing the workload and maintenance time for maintenance personnel and improving equipment maintenance efficiency.

[0043] Optionally, the flow guide cavity 80 is detachably connected to the base plate 12, the hydraulic oil tank 20 is provided with an oil filling port 28 corresponding to one of the flow guide cavities 80, and the side of the hydraulic oil tank 20 is provided with a level gauge 29 corresponding to the oil filling port 28.

[0044] Specifically, the guide cavity 80 is detachably connected to the base plate 12. This detachable connection facilitates the installation and removal of the guide cavity 80, enabling maintenance and repair of the hydraulic power station. For example, when hydraulic oil needs to be added, simply remove the guide cavity 80 corresponding to the filler port 28, and hydraulic oil can be added to the hydraulic oil tank 20 through the filler port 28. Furthermore, a level gauge 29 corresponding to the filler port 28 is installed on the side of the hydraulic oil tank 20. The level gauge 29 can display the hydraulic oil level in the hydraulic oil tank 20 in real time, allowing operators to easily understand the hydraulic oil level and the required amount of hydraulic oil to be added.

[0045] The airflow guiding cavity 80 includes an air inlet 82 corresponding to the first air inlet 122 and an air outlet 84 corresponding to the cooling fan 36. Located on opposite sides of the chassis 10, the airflow guiding cavity 80 enables simultaneous air intake from both sides, thereby increasing the airflow volume. Additionally, the airflow guiding cavity 80 is provided with a clearance opening 86 to avoid interference with the level gauge 29 when connected to the base plate 12, thus improving the compactness of the connection.

[0046] like Figure 2 As shown, a plurality of air guide plates 14 corresponding to the first radiator 40 are provided on the rear side of the chassis 10. The adjacent air guide plates 14 are arranged in parallel and the air guide plates 14 are arranged obliquely downward. Through holes 142 are arranged in an array on the air guide plates 14.

[0047] Specifically, the function of the air guide plate 14 is to guide the airflow blown out by the cooling fan 36, making it flow more evenly across the first radiator 40 and improving the heat dissipation effect. The downwardly angled air guide plate 14 allows the airflow to be discharged better, preventing airflow from accumulating at the rear of the chassis 10 and affecting the heat dissipation effect, and also reduces the chance of rainwater getting in when used outdoors. The through hole 142 ensures that the airflow can pass smoothly through the air guide plate 14, while also playing a certain role in rectifying the airflow.

This hydraulic power station contains the same structure and beneficial effects as the heat dissipation structure of the hydraulic power station in the foregoing embodiments. The structure and beneficial effects of the heat dissipation structure of the hydraulic power station have been described in detail in the foregoing embodiments and will not be repeated here.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
