Abstract
Description
Technical Field
[0001] This utility model relates to the field of power station box heat dissipation technology, and in particular to a closed-type air-cooled diesel power station box heat dissipation system. Background Technology
[0002] An air-cooled diesel engine power station is an integrated power generation device that combines an air-cooled diesel engine, generator, and control system. The entire unit is sealed within a single enclosure, making it easy to transport and store. Its core feature is that it utilizes air to directly cool the diesel engine. It has a compact structure and is suitable for various environments.
[0003] The cooling system of the air-cooled diesel generator set is one of its core design features. It needs to efficiently remove the large amount of heat generated by the diesel engine and generator during operation to ensure stable operation of the equipment at rated power. The goal is to ensure that sufficient cool air enters from one side of the set and, after flowing through the heat-generating components, becomes hot air and is smoothly discharged from the other side, avoiding airflow short-circuiting and the accumulation of hot air inside the set.
[0004] Existing heat dissipation systems include technologies such as forced ventilation and enclosure heat dissipation structures.
[0005] Forced ventilation includes a centrifugal fan, a shroud, and air ducts. The fan is directly driven by the diesel engine spindle, providing the main airflow required for cooling. The shroud and air ducts precisely direct cooling air to high-temperature components of the diesel engine, such as the cylinders, cylinder heads, and oil coolers, ensuring no cooling dead zones.
[0006] The enclosure's heat dissipation structure includes air inlets and exhaust vents, and a radiator. The air inlets and exhaust vents are strategically positioned to create a smooth airflow path. The radiator allows cooling air to carry away more heat as it flows through.
[0007] In existing technologies, the engine's own cooling fan draws air from the housing to blow and cool the engine and generator. However, due to the hot air recirculation inside the housing, the air temperature is often high, resulting in poor cooling performance. To reduce the impact of hot air recirculation, high-volume fans are often used, and even additional suction fans or baffles are required. This increases the power consumption of the fans and the cost and weight of the power station housing, failing to meet user requirements.
[0008] In summary, the existing air-cooled diesel closed-type power station box heat dissipation system has certain defects and does not meet people's usage requirements. Therefore, we propose an air-cooled diesel closed-type power station box heat dissipation system. Utility Model Content
[0009] The main purpose of this utility model is to provide a closed-type air-cooled diesel power station box heat dissipation system. It uses connectors to limit the inner and outer wall components, forming a frame. The modular structure allows each part to be arbitrarily disassembled and transported separately, making the whole lighter and smaller in size during transport. It has good performance and good application prospects, and can effectively solve the problems in the background technology.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0038] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0039] This application provides a closed-type air-cooled diesel generator box cooling system, which solves the problem that in the prior art, the engine's own cooling fan draws air from inside the box to blow and cool the engine and generator. Often, due to the hot air recirculation inside the box, the air temperature is high, resulting in poor cooling effect. In order to reduce the impact of hot air recirculation, a large air volume fan is often used, and even an intake fan or more baffles are required. This increases the power consumption of the fan and the cost and weight of the generator box.
[0040] Example 1
[0041] like Figure 1-6 As shown, a closed-type air-cooled diesel engine power station cooling system is applied to an air-cooled diesel engine power station box; it includes a power station box body 1, an engine 2, an air inlet assembly, and an air outlet:
[0042] The engine 2 is mounted on the base plate of the power station housing 1 via a suspension bracket, ensuring high stability. The air intake assembly is located on the power station housing 1 and is used to introduce outside air into the interior of the power station housing 1 to dissipate heat from the engine 2. This method of guiding outside air into the interior of the power station housing 1 achieves heat dissipation, as the outside air temperature is lower than the inside air temperature, resulting in good heat dissipation. The air outlet is located at the front of the power station housing 1 and is used to exhaust hot air from inside the power station housing 1. The design of the air outlet allows for air circulation, thereby improving the heat dissipation effect. The cooling air is directly introduced from outside the power station housing 1, resulting in a lower temperature and better cooling effect.
[0043] This solution provides a closed-loop cooling system for air-cooled diesel generator sets. It draws air directly from outside the set to reduce the temperature of the air and improve the cooling effect. At the same time, it uses a fan with an appropriate airflow to ventilate the inside of the set and reduce hot air recirculation. This ensures thermal balance inside the set and achieves the goals of low power consumption, low cost, and lightweight design. It has good performance and promising application prospects.
[0044] Example 2
[0045] Based on Example 1, such as Figure 1-3 As shown, this example also records the following structure:
[0046] The air intake assembly includes an air inlet 3 and a wind guide. During use, cold outside air enters the interior of the power station housing 1 through the air inlet 3 and the wind guide, and directly contacts the engine 2 to directly cool the engine 2.
[0047] Air inlet 3 is located at the front end of the power station box 1. Outside cold air enters the cold air guide along air inlet 3 to form cooling air. The wind guide is connected to air inlet 3 and engine 2. The wind guide directly guides the cooling air entering from air inlet 3 to engine 2, thereby achieving heat dissipation of engine 2.
[0048] The wind-guided component is equipped with a drive unit inside to guide wind into the power station box 1. The drive unit can accelerate the flow of outside air, thereby achieving a better heat dissipation effect.
[0049] The wind-powered guide includes an air inlet duct 4 and an air guide cover 5. One end of the air inlet duct 4 is connected to the air inlet 3, and the air guide cover 5 is installed on the engine 2. The other end of the air inlet duct 4 is connected to the air guide cover 5.
[0050] In use, the air intake duct 4 guides the movement of cooling air, which then moves to the air guide shroud 5. The air guide shroud 5 has a large area, which can diffuse the cooling air, allowing it to come into contact with the engine 2 and dissipate heat and cool the engine 2.
[0051] The air inlet duct 4 includes a duct body and two sets of connecting parts. The duct body is a flexible pipe that can be extended and retracted to eliminate the influence of relative movement between the engine and the housing when the engine is running.
[0052] The drive unit includes a generator 6 and an engine fan 7, which are connected to the engine 2 in sequence. The generator 6 and engine fan 7 are built into the engine and can accelerate the airflow, allowing cold air from the outside to quickly enter the interior of the air guide shroud 5 to cool the engine 2.
[0053] A side opening is provided on the side end face of the power station box 1 near the air inlet 3. A box fan 8 is installed on the side opening to blow air into the interior of the power station box 1 for cooling.
[0054] This solution provides a closed-type air-cooled diesel generator box cooling system, which has lower cooling air temperature for the engine and generator, resulting in better cooling effect for the unit. At the same time, the side-added box fan 8 can further reduce the air temperature inside the box, which is conducive to the unit achieving thermal balance. It has good performance and promising application prospects.
[0055] Example 3
[0056] Based on Example 2, such as Figure 1-6 As shown, this example also records the following structure:
[0057] An auxiliary cooling component is provided on the air guide shroud 5. The auxiliary cooling component is connected to the temperature sensor on the engine 2. When the temperature sensor on the engine 2 detects that the engine temperature is too high, the auxiliary cooling component is activated. A wind guide is provided at the connection between the air guide shroud 5 and the air intake duct 4. The wind guide is connected to the auxiliary cooling component.
[0058] The auxiliary cooling component includes a thermoelectric cooling chip 9 embedded in the air guide shroud 5. A heat-conducting plate 10 is fixedly installed on the hot end face of the thermoelectric cooling chip 9. The heat-conducting plate 10 works with the cabinet fan 8 to dissipate heat from the hot end of the thermoelectric cooling chip 9, making the working environment of the thermoelectric cooling chip 9 better and improving its performance. The cold end face of the thermoelectric cooling chip 9 is connected to the water circulation device 12. When the auxiliary cooling component is activated, the thermoelectric cooling chip 9 cools down, and works with the water circulation device 12 to cool the air guide component. When the cooling air comes into contact with the air guide component, the temperature is further reduced, improving the cooling effect.
[0059] The wind-guided component includes several sets of hollow wind guide plates 11 facing different directions. The hollow wind guide plates 11 are connected to a water circulation device 12, which reduces the temperature of the hollow wind guide plates 11 through water circulation.
[0060] This solution provides a closed-type air-cooled diesel power station box heat dissipation system. Its hollow air guide plate 11 not only diffuses the cooling air, but also works with auxiliary cooling components to further reduce the temperature of the cooling air during the cooling air guidance process, thereby greatly improving the air cooling effect. It has good performance and good application prospects.
[0061] It should be noted that this utility model describes a closed-type air-cooled diesel generator box cooling system. In use, the generator 6 and the engine fan 7 work together. The engine 2 drives the generator 6 to generate electricity and at the same time drives the engine fan 7 to rotate, drawing in air. The cold air from the outside is drawn into the air intake duct 4 through the air inlet 3 to form cooling air, which passes through the air guide shroud 5 to dissipate heat from the generator 6 and the engine 2. At the same time, the box fan 8 starts to draw outside air into the engine 2 to cool the engine 2, and then moves to the air outlet to be discharged.
[0062] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
