Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a combined air-water-oil radiator for mining trucks. Background Technology

[0002] Large mining trucks operate under complex and harsh conditions, generating significant heat from their engines, control systems, braking systems, and hydraulic systems. Efficient heat dissipation is crucial for ensuring normal equipment operation. Traditional radiators are often individually designed with air, water, or oil cooling, resulting in issues such as large space requirements, low cooling efficiency, and complex installation and maintenance. For example, air-cooled radiators, due to their high temperatures, typically use aluminum radiators, but suffer from poor ventilation and maintainability; water-cooled radiators offer strong heat dissipation capacity but require a large cooling system volume and tend to occupy significant space; oil-cooled radiators are usually designed for specific components, and their separate placement complicates the overall vehicle cooling layout. Therefore, developing a combined radiator that integrates air, water, and oil cooling functions, improves cooling efficiency, and facilitates installation and maintenance is imperative. Utility Model Content

[0003] The purpose of this utility model is to provide a combined air-water-oil radiator for mining trucks, so as to solve the problems of large space occupation, low heat dissipation efficiency, and complex installation and maintenance of existing mining truck cooling systems, achieve efficient integrated heat dissipation, and improve the reliability and stability of mining truck operation.

[0004] To achieve the above objectives, this utility model provides a combined air-water-oil radiator for mining trucks, comprising a frame and an air-cooling module, a water-cooling module, and an oil-cooling module installed within the frame. A radiator fan is fixedly installed on the front side of the frame. Each of the air-cooling, water-cooling, and oil-cooling modules includes multiple parallel heat dissipation tubes. The air inlet of the air-cooling module is connected to the engine turbocharger, and the air outlet is connected to the engine intake manifold. The water inlet and outlet water pipes of the water-cooling module are connected to the engine's cooling system. The oil inlet and outlet oil pipes of the oil-cooling module are connected to the corresponding oil lines of the mining truck that require cooling. An expansion tank for adding coolant to the water-cooling module is fixedly installed at the top of the frame, and the exhaust pipe of the water-cooling module is connected to the expansion tank.

[0005] Furthermore, the oil cooling module includes a hydraulic oil cooling module and an engine oil cooling module arranged side by side. The hydraulic oil cooling module is located on the side away from the radiator fan, and the engine oil cooling module is located on the side closer to the radiator fan. The water cooling module includes an engine cooling module.

[0006] Furthermore, the water-cooling module includes an engine cooling module and a controller cooling module, and the oil-cooling module includes an oil cooling module. The oil cooling module and the controller cooling module are arranged side by side. The controller cooling module is located on the side away from the radiator fan, and the oil cooling module is located on the side closer to the radiator fan. Both the controller cooling module and the engine cooling module are connected to the expansion tank.

[0007] Furthermore, the expansion tank is divided into two expansion spaces, and each expansion space is equipped with a pressure cover, an exhaust port, a water supply port, and a level gauge.

[0008] Furthermore, an air guide shroud is fixedly installed on the front side of the frame, the cooling fan is installed inside the air guide shroud, and a protective net covering the outside of the cooling fan is fixedly installed on the air guide shroud.

[0009] Furthermore, an exhaust pipe is connected between the water-cooling module and the expansion tank.

[0010] Furthermore, a limiting plate for fixing the middle position of the heat dissipation tube is fixedly installed at the middle position of the frame.

[0011] Furthermore, the frame is provided with a tie rod seat and a base seat on its side, and both the tie rod seat and the base seat are provided with connection holes.

[0012] Furthermore, the heat dissipation tube of the oil-cooled module is provided with a spiral strip inside.

[0013] Furthermore, the heat dissipation core is a single copper tube strip heat dissipation core.

[0014] This utility model's technical solution integrates air-cooled, water-cooled, and oil-cooled modules within the same frame, effectively combining the functions of cooling the turbocharger intake of the mining truck engine, cooling the engine's coolant system, and cooling the vehicle's oil circuit. This significantly reduces the space occupied by traditional independent radiators and simplifies the overall vehicle cooling system layout. Each cooling module uses multiple parallel cooling tubes, along with a cooling fan fixed to the front of the frame, enabling efficient cooling of three different media: air, water, and oil. This ensures stable operation of the engine and related oil circuit components under complex and harsh conditions. Simultaneously, the expansion tank fixed at the top of the frame allows for convenient addition of coolant to the water-cooled module. The high degree of integration of the overall structure not only reduces installation difficulty but also facilitates subsequent maintenance, effectively solving the problems of large space occupation and complex installation and maintenance in existing mining truck cooling systems.

[0027] Example 1

[0028] like Figures 1-5 As shown, this utility model provides a combined air-water-oil radiator for mining trucks, including a frame 4 and an air-cooling module 12, a water-cooling module 15, and an oil-cooling module installed within the frame 4. The frame 4 serves as an integral support structure, primarily constructed from high-strength carbon steel plates welded together. A partition plate is provided inside the frame 4, dividing the space into an air-cooling zone, a water-cooling zone, and an oil-cooling zone, respectively for installing the air-cooling module 12, the water-cooling module 15, and the oil-cooling module. A radiator fan 18, which is a suction fan, is fixedly installed on the front side of the frame 4. An air guide shroud 9 is also fixedly installed on the front side of the frame 4, with the radiator fan 18 installed inside the air guide shroud 9. A protective net 10, covering the outside of the radiator fan 18, is fixedly installed on the air guide shroud 9.

[0029] The air-cooled module 12, water-cooled module 15, and oil-cooled module all include multiple parallel heat dissipation tubes 16. In this embodiment, the heat dissipation tube 16 is a single copper tube strip heat dissipation tube 16. Both ends of the heat dissipation tube 16 are supported and sealed by high-temperature resistant fluororubber sleeves. A limiting plate 22 for fixing the middle position of the heat dissipation tube 16 is fixedly installed in the middle position of the frame 4. Each copper tube is interlocked with the tube support block 19, and the front and rear limiting plates 22 restrict these support blocks 19 to ensure that the copper tube is stable and reliable during vehicle operation. The side of the frame 4 is provided with a tie rod seat 5 and a base seat 6. Both the tie rod seat 5 and the base seat 6 are provided with connection holes. The frame 4 and the mining truck frame are fixed at the tie rod seat 5 and the base seat 6 by bolts and shock-absorbing rubber pads to reduce the impact of vibration transmission on the radiator.

[0030] The air inlet of the air-cooled module 12 is connected to the engine turbocharger, and the air outlet is connected to the engine intake manifold, which is used to cool the compressed hot air at the output end of the engine turbocharger.

[0031] The water-cooling module 15 can be located in the middle or lower part of the frame 4, including coolant inlet and outlet water tanks, inlet and outlet water pipes, exhaust port, water supply port, etc. The inlet and outlet water pipes of the water-cooling module 15 are connected to the engine's cooling system. The coolant flows in the pipes and exchanges heat with the fan air through the heat dissipation core 16 to cool the engine coolant.

[0032] The oil cooling module's inlet and outlet oil pipes are connected to the corresponding oil circuits that the mining truck needs to cool. In this embodiment, the oil cooling module includes a hydraulic oil cooling module 14 and an engine oil cooling module 13 arranged side by side. The hydraulic oil cooling module 14 is located on the side away from the radiator fan 18, and the engine oil cooling module 13 is located on the side closer to the radiator fan 18. The arrangement is a front-to-back structure. According to the inlet and outlet temperatures of each block, the heat dissipation requirements, and the temperature gradient of the flowing cooling air, this ensures that the cooling air from the fan of the hydraulic oil cooling module 14 entering the engine oil cooling module 13 can still maintain a suitable temperature gradient requirement. When the flow rate of the hydraulic oil and engine oil copper tube core is relatively low, a spiral band 21 can be added inside the radiator core 16 to increase the heat exchange area and improve the heat exchange coefficient. At this time, the water cooling module 15 only includes the engine cooling module.

[0033] An expansion tank 1 for adding coolant to the water-cooled module 15 is fixedly installed at the top of the frame 4. The expansion tank 1 is divided into two expansion spaces. Each expansion space is equipped with a pressure cover 2, an exhaust port, a water supply port and a level gauge 3. An exhaust pipe 7 connects the water-cooled module 15 and the expansion tank 1.

[0034] Example 2

[0035] like Figures 6-7As shown, the difference between this embodiment and embodiment 1 is that: the water-cooled module 15 includes an engine cooling module and a controller cooling module 17, and the oil-cooled module includes an oil cooling module 13. The oil cooling module 13 and the controller cooling module 17 are arranged side by side. The controller cooling module 17 is located on the side away from the radiator fan 18, and the oil cooling module 13 is located on the side close to the radiator fan 18. Both the controller cooling module 17 and the engine cooling module are connected to the expansion tank 1 through the cooling water pipe and the exhaust pipe 7.

[0036] The installation process of the radiator is as follows: First, the welded frame 4 is pressure tested for sealing according to design requirements to ensure that there are no leaks in each slot and pipe end. After the test, the interior is cleaned and the exterior is painted before being transported to the assembly area. After the heat dissipation cores 16 of each cooling module are made, the support blocks 19 are installed first. The upper and lower sealing sleeves 20 are installed on the perforated plates of each cooling module, and then the heat dissipation cores 16 are inserted. The front and rear limit plates 22 are installed, and the heat dissipation cores 16 are fixed at the support blocks 19 using pressure strips 23. The sealing performance of the copper cores is then tested by pressure testing. Finally, the expansion box 1 is installed on top of the radiator, and the exhaust pipe 7, water supply pipe 8, etc. of the expansion box 1 are connected to the corresponding modules of the radiator. Then, the vehicle loading operation is carried out. The radiator is hoisted to the predetermined installation position on the vehicle, and the radiator is fixed to the frame by bolts passing through the shock-absorbing rubber pads through the tie rod seat 5 and the base seat 6 on the frame 4. Then, connect the air inlet and outlet pipes of the air-cooled module 12 to the turbocharger system of the engine to ensure smooth airflow; connect the water inlet and outlet water pipes of the water-cooled module 15 to the engine cooling system to ensure good sealing of the coolant circulation loop; connect the oil pipes of the oil-cooled module to the oil circuit system and other corresponding components to ensure that the oil connection is firm and leak-free.

[0037] When the mining truck is running, the high-temperature compressed air generated by the engine exits from the turbocharger and enters the air-cooled heat exchanger. After cooling, it returns to the engine manifold. The high-temperature coolant enters the coolant tank through the inlet pipe of the water-cooling module 15, flows in the radiator core, and exchanges heat with the outside air. The cooled coolant returns to the engine through the outlet pipe. At the same time, the high-temperature oil from components such as the hydraulic (or braking, control) system enters the radiator of the oil-cooling module through oil pipes. After exchanging heat with the cold air provided by the radiator fan 18, it is cooled down and then returns to the corresponding components. The initial water coolant is added to the radiator through the top expansion tank 1, and the exhaust from the water-cooled radiator is also discharged to the top of the expansion tank 1. The oil-cooled radiator is connected to the mining truck's oil circuit system and has a separate oil tank to store oil, absorb the expanded oil, and receive exhaust from the oil-cooling module.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
