Abstract
Description
Technical Field
[0001] This application relates to the field of gas engine cooling technology, specifically a gas engine cooling circulation device. Background Technology
[0002] Currently, gas engines are widely used in power generation, transportation, and many other fields. However, in high-temperature environments, excessively high internal engine temperatures can lead to performance degradation or even damage. Therefore, the cooling system is crucial for ensuring the normal operation of the engine. Existing cooling systems mainly include air cooling and water cooling, with water cooling being widely used due to its higher heat dissipation efficiency.
[0003] Air-cooled systems use fans to force airflow and remove heat. Their advantages include simple structure and low cost, but their cooling effect is limited and cannot meet the needs of high-performance engines. Water-cooled systems, on the other hand, use a water pump to circulate coolant near the heat source to absorb heat, which is then released into the air through the radiator. This system has good cooling performance, but it also has some problems.
[0004] However, the air-cooled system has low heat dissipation efficiency and cannot meet the high-intensity continuous working requirements. At the same time, although the water-cooled system has a better heat dissipation effect, there is still room for improvement in its heat dissipation effect. In order to solve the above problems, a gas engine cooling circulation device is proposed. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a gas engine cooling circulation device that can improve the heat dissipation efficiency of gas engine cooling and ensure stable engine operation in high-temperature environments.
[0006] To achieve the above objectives, this application provides the following technical solution: a gas engine cooling circulation device, comprising a base and a gas engine body fixedly connected to the upper surface of the base. A circulation cooling mechanism and a control mechanism are provided above the base. The circulation cooling mechanism includes a cooling box fixedly connected to the upper surface of the base and a cavity opened on the back of the gas engine body. A first centrifugal pump and a second centrifugal pump are installed on one side of the gas engine body. The output end of the first centrifugal pump is connected to a delivery pipe, and the output end of the delivery pipe is connected to a first circulation cooling pipe. Multiple phase change heat pipes are fixedly connected to the inner wall of the cavity. One end of each phase change heat pipe is in contact with the outer surface of the first circulation cooling pipe. The output end of each phase change heat pipe is connected to a second circulation cooling pipe, and the output end of the second circulation cooling pipe is connected to the input end of the second centrifugal pump. A radiator and a first electrically controlled fan are fixedly connected to the other side of the gas engine body. The outer surface of the second circulation cooling pipe is embedded in the inner wall of the radiator.
[0007] The above-described scheme significantly improves heat dissipation efficiency and extends the service life of the gas engine by implementing a circulating cooling mechanism. The combination of air and water cooling ensures stable engine operation in high-temperature environments. When the first and second centrifugal pumps are activated, the coolant in the cooling tank circulates through the delivery pipe, the first circulating cooling pipe, and the second circulating cooling pipe, achieving water cooling of the gas engine. The phase-change heat pipe helps slow down the rate of temperature rise and enhances the overall stability of the cooling function. Simultaneously, embedding the second circulating cooling pipe inside the radiator accelerates the reduction of the coolant temperature inside the second circulating cooling pipe. The installed first electrically controlled fan accelerates the radiator's heat dissipation. Finally, the control mechanism enables intelligent control, making the cooling system more flexible and adaptable to different operating conditions.
[0008] Furthermore, the output end of the delivery pipe passes through the base and extends into the interior of the cavity, and both ends of the second circulating cooling pipe are fixedly connected to the inner wall of the gas engine body.
[0009] The above scheme defines the positional relationship of the second circulation cooling pipe, enabling the second circulation cooling pipe to be installed more stably inside the gas engine body.
[0010] Furthermore, the input end of the first centrifugal pump is connected to the interior of the cooling tank, and the output end of the second centrifugal pump is connected to the interior of the cooling tank.
[0011] With the above scheme, when the first centrifugal pump starts, the coolant inside the cooling tank can be delivered to the delivery pipe, and when the second centrifugal pump starts, the coolant inside the second circulating cooling pipe can be delivered to the cooling tank, thereby enabling the coolant to achieve efficient circulation.
[0012] Furthermore, the inner top wall of the cavity is provided with evenly distributed heat dissipation vents, and a second electric control fan is installed above the heat dissipation vents. The second electric control fan is fixedly connected to the top of the gas engine body.
[0013] The above solution allows the heat dissipation vents and the second electronically controlled fan to enhance airflow around the first circulating cooling pipe, reducing the temperature difference between the hot liquid and the cold air, thereby more effectively lowering the temperature of the coolant inside the first circulating cooling pipe.
[0014] Furthermore, a liquid injection port is installed on the top of the cooling tank, and the output end of the liquid injection port is connected to the interior of the cooling tank.
[0015] The above-mentioned solution allows for the addition of coolant to the cooling tank through the injection port, ensuring the proper functioning of the device's circulating cooling system.
[0016] Furthermore, a drain port is installed at the bottom of the cooling tank, and the inlet of the drain port is connected to the interior of the cooling tank.
[0017] The above-described solution allows for the periodic replacement of the coolant inside the cooling tank via a drain outlet.
[0018] Furthermore, the control mechanism includes a control box fixedly connected to the upper surface of the base. A power module and a PLC controller are fixedly connected to the top and bottom walls of the control box, respectively. The electrical components and power module inside the circulating cooling mechanism are all electrically connected to the PLC controller. Ventilation openings are provided on the outer surface of the control box.
[0019] The above scheme provides power to the device through a power module, and the PLC controller controls the electrical components in the device to operate, achieving more intelligent control, making the cooling operation more flexible and adaptable to different working conditions, and the ventilation openings ensure air circulation inside and outside the control box, preventing overheating inside the control box.
[0020] Furthermore, a high-precision temperature sensor is fixedly connected to the inner wall of the cavity, and the high-precision temperature sensor is electrically connected to the PLC controller.
[0021] The high-precision temperature sensor described above can detect the temperature of the gas engine body and feed the signal back to the PLC controller.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This gas engine cooling circulation device significantly improves heat dissipation efficiency and extends the service life of the gas engine through its circulation cooling mechanism. It employs a combination of air cooling and water cooling to ensure stable engine operation in high-temperature environments. When the first and second centrifugal pumps are activated, the coolant in the cooling tank is transported through the delivery pipe, the first circulating cooling pipe, and the second circulating cooling pipe, achieving water cooling of the gas engine. The phase-change heat pipe helps slow down the rate of temperature rise and enhances the overall stability of the cooling function. The installed first and second electrically controlled fans provide air cooling, while the second circulating cooling pipe, embedded inside the radiator, accelerates the reduction of the coolant temperature inside the second circulating cooling pipe.

Detailed Implementation
[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 2 and Figure 5This embodiment of a gas engine cooling circulation device includes a base 1 and a gas engine body 2 fixedly connected to the upper surface of the base 1. A circulation cooling mechanism 3 and a control mechanism 4 are provided above the base 1. The circulation cooling mechanism 3 includes a cooling box 301 fixedly connected to the upper surface of the base 1 and a cavity 302 opened on the back of the gas engine body 2. A first centrifugal pump 303 and a second centrifugal pump 310 are installed on one side of the gas engine body 2. The output end of the first centrifugal pump 303 is connected to a delivery pipe 304. The input end of the first centrifugal pump 303 is connected to the interior of the cooling box 301. The output end of the second centrifugal pump 310 is connected to the interior of the cooling box 301. When the first centrifugal pump 303 is started, it can deliver the coolant inside the cooling box 301 to the delivery pipe 304. When the second centrifugal pump 310 is started, it can deliver the coolant inside the second circulation cooling pipe 307 to the cooling box 301, thereby enabling the coolant to achieve efficient circulation.
[0033] Please see Figure 3 , Figure 4 and Figure 5 The output end of the delivery pipe 304 passes through the base 1 and extends into the cavity 302. The output end of the delivery pipe 304 is connected to the first circulating cooling pipe 305. The coolant in the delivery pipe 304 can be delivered to the first circulating cooling pipe 305 to cool the gas engine body 2. Multiple phase change heat pipes 306 are fixedly connected to the inner wall of the cavity 302. One end of each phase change heat pipe 306 is in contact with the outer surface of the first circulating cooling pipe 305. The phase change heat pipes 306 can slow down the rate of temperature rise of the gas engine body 2 and quickly transfer the heat of the gas engine body 2 to the surrounding area of the first circulating cooling pipe 305, thereby accelerating the heat exchange rate of the coolant inside the first circulating cooling pipe 305 and improving the cooling effect on the gas engine body 2. The output end of the phase change heat pipe 306 is connected to the second circulating cooling pipe 307. Both ends of the pipe 307 are fixedly connected to the inner wall of the gas engine body 2, which limits the positional relationship of the second circulating cooling pipe 307 and allows the second circulating cooling pipe 307 to be installed more stably inside the gas engine body 2. The output end of the second circulating cooling pipe 307 is connected to the input end of the second centrifugal pump 310. The other side of the gas engine body 2 is fixedly connected to the radiator 308 and the first electric fan 309. The outer surface of the second circulating cooling pipe 307 is embedded in the inner wall of the radiator 308. The radiator 308 can conduct heat out of the coolant flowing inside the second circulating cooling pipe 307, thereby achieving the effect of cooling the coolant inside the second circulating cooling pipe 307, which is beneficial to the circulation of coolant. When the first electric fan 309 is started, it can accelerate the airflow around the radiator 308 and improve the heat dissipation effect of the radiator 308.
[0034] Please see Figure 2 , Figure 4 and Figure 5 The inner top wall of cavity 302 is provided with evenly distributed heat dissipation vents 311. A second electric control fan 312 is installed above the heat dissipation vents 311 and is fixedly connected to the top of the gas engine body 2. By setting the heat dissipation vents 311 and the second electric control fan 312, the airflow around the first circulating cooling pipe 305 can be enhanced, reducing the temperature difference between the hot liquid and the cold air, thereby more effectively reducing the temperature of the coolant inside the first circulating cooling pipe 305. A liquid injection port 313 is installed on the top of the cooling box 301. The output end of the liquid injection port 313 is connected to the interior of the cooling box 301. Coolant can be added to the cooling box 301 through the liquid injection port 313 to ensure the circulating cooling operation of the device. A drain port 314 is installed at the bottom of the cooling box 301. The input end of the drain port 314 is connected to the interior of the cooling box 301. The coolant inside the cooling box 301 can be replaced periodically through the drain port 314.
[0035] Please see Figure 1 , Figure 2 and Figure 4 The control mechanism 4 includes a control box 401 fixedly connected to the upper surface of the base 1. A power module 402 and a PLC controller 403 are fixedly connected to the top and bottom walls of the control box 401, respectively. The electrical components inside the circulating cooling mechanism 3 and the power module 402 are all electrically connected to the PLC controller 403. A ventilation opening 404 is provided on the outer surface of the control box 401. The power module 402 provides power to the device, and the PLC controller 403 controls the electrical components within the device, achieving more intelligent control and making the cooling operation more flexible and adaptable to different working conditions. 4. It can ensure the circulation of air inside and outside the control box 401 and avoid overheating inside the control box 401. A high-precision temperature sensor 405 is fixedly connected to the inner wall of the cavity 302. The high-precision temperature sensor 405 is electrically connected to the PLC controller 403. The high-precision temperature sensor 405 can detect the temperature of the gas engine body 2 and feed the signal back to the PLC controller 403. When the high-precision temperature sensor 405 detects that the temperature of the gas engine body 2 is too high, the PLC controller 403 can control the first electric fan 309 and the second electric fan 312 to start, thereby improving the cooling efficiency.
[0036] In this embodiment, a gas engine cooling circulation device significantly improves heat dissipation efficiency and extends the service life of the gas engine body 2 through the set circulation cooling mechanism 3. It adopts a combination of air cooling and water cooling to ensure stable operation of the engine in high-temperature environments. When the first centrifugal pump 303 and the second centrifugal pump 310 are started, the coolant in the cooling tank 301 can be circulated through the delivery pipe 304, the first circulation cooling pipe 305 and the second circulation cooling pipe 307 to achieve water cooling of the gas engine body 2. The set phase change heat pipe 306 helps to slow down the rate of temperature rise and enhance the stability of the overall cooling function. The installed first electric fan 309 and the second electric fan 312 can achieve the effect of air cooling. At the same time, the second circulation cooling pipe 307 is embedded in the radiator 308, which can accelerate the reduction of the temperature of the coolant inside the second circulation cooling pipe 307. Finally, the set control mechanism 4 can achieve more intelligent control, making the cooling system more flexible and adaptable to different operating conditions.
[0037] The working principle of the above embodiment is as follows: After the gas engine body 2 starts working, the first centrifugal pump 303 and the second centrifugal pump 310 will start working, so that the coolant in the cooling tank 301 can be circulated and transported sequentially through the delivery pipe 304, the first circulating cooling pipe 305 and the second circulating cooling pipe 307, so that the coolant can flow through the interior of the gas engine body 2 and directly cool the gas engine body 2. The multiple phase change heat pipes 306 can slow down the rate of temperature rise of the gas engine body 2, optimize the cooling effect, and quickly transfer the heat of the gas engine body 2 to the surrounding area of the first circulating cooling pipe 305, thereby increasing the heat exchange rate of the coolant inside the first circulating cooling pipe 305. When the coolant is transported to the second circulating cooling pipe 307, the heat can be conducted away through the radiator 308, thereby realizing the cooling of the second circulating cooling pipe 307. 7. The internal coolant is cooled, which is beneficial for the circulation of coolant. At the same time, the high-precision temperature sensor 405 continuously monitors the temperature of the gas engine body 2 and feeds the data back to the PLC controller 403 for processing. The PLC controller 403 will decide whether to turn on the first electric fan 309 and the second electric fan 312 based on the current temperature value. When the temperature exceeds the preset threshold, the first electric fan 309 and the second electric fan 312 will be activated to increase airflow and accelerate heat dissipation. During the entire operation, the PLC controller 403 will control the operation of the first electric fan 309 and the second electric fan 312 to ensure that the coolant is always at the optimal flow rate, thereby achieving the best heat dissipation effect. When the first electric fan 309 is activated, it can circulate the air around the radiator 308. When the second electric fan 312 is activated, it can accelerate the airflow inside the cavity 302, making it more practical.
