Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, and in particular to a fusion-type lightweight cooling device. Background Art

[0002] When the internal combustion engine is running, the temperature of the locomotive's cooling water, lubricating oil, traction motor and electrical appliances or transmission oil of the hydraulic transmission device will continue to rise. If not cooled, it will affect the power of the diesel engine and transmission device, reduce working efficiency, age and deteriorate the lubricating oil, damage lubrication, affect the service life of locomotive parts, and even damage them. Therefore, necessary cooling measures are taken on the internal combustion locomotive, and some devices are set up to ensure that the heat generated by the diesel engine and transmission device during operation can be discharged to the atmosphere in a timely and appropriate manner, so that its temperature is maintained within the allowable range, so as to improve the thermal strength and lubrication condition of the parts, improve the economy and reliability of the internal combustion locomotive, and extend its service life. This is the main task of the cooling system of the internal combustion locomotive.

[0003] Most of the existing cooling devices for diesel locomotives are in the form of a combination of a radiator and an external header. The radiator is arranged in an eight-shaped shape and has a high height space requirement. For example, Patent No.: CN101698410A, Patent Name: Top-mounted Cooling Device, Announcement Date: 20121114; It is necessary to design a complicated header structure outside the cooling device, and a complete set of header fixing devices is required. The weight of the cooling device design is generally heavy, the structure is complex and occupies a large amount of locomotive space, the cooling device structure space utilization rate is low, and the radiator end pipeline system is crowded, the weight exceeds the limit, there are many pipe joints, and the risk of pipeline leakage is high. Therefore, it cannot meet the lightweight and modular design requirements of future locomotives. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fusion lightweight cooling device based on a modular and lightweight design concept, which fully utilizes the limited locomotive space to highly integrate the cooling device with a lightweight design.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a fusion-type lightweight cooling device, comprising a radiator, box beams are arranged on both sides of the radiator, the radiator is installed on the top of the locomotive through the box beams, and a header box is arranged at the outlet end of the radiator; in order to utilize the wasted space of the original steel structure, improve the high degree of integration, multi-purpose and multi-function, and save space and its own weight at the same time, one side of the box beam is a radiator installation bearing structure for installing the radiator, and the other side is a cooling device installation bearing structure for installing the entire cooling device on the locomotive frame, the middle section is a header structure for flowing out the intercooling fluid and the high-temperature fluid, the header structure on one side is provided with a high-temperature header for flowing out the high-temperature fluid, and the header structure on the other side is provided with an intercooling header for flowing out the intercooling fluid; the inner cavity of the header box is divided into a high-temperature cavity and an intercooling cavity, the structure of the header box greatly reduces the connection of the pipeline joints, the integration is high, and the risk of pipeline leakage is indirectly reduced, and the header box is connected to the radiator via two universal interfaces, and the modularization degree is high; the internal pipelines among the radiator, the header box and the header structure are connected.

[0006] Furthermore, an intercooler inlet and a high-temperature inlet are provided at the inlet end of the radiator, a high-temperature outlet and an intercooler outlet are provided at the outlet end of the radiator, a high-temperature layer and an intercooler layer are provided inside the radiator, the intercooler inlet is connected to the intercooler layer inside the radiator, the high-temperature inlet is connected to the high-temperature layer inside the radiator, the high-temperature outlet is connected to the high-temperature layer inside the radiator, the intercooler outlet is connected to the intercooler layer inside the radiator, the high-temperature outlet is connected to the high-temperature cavity, and the intercooler outlet is connected to the intercooler cavity.

[0007] Furthermore, a high-temperature cooling circulation loop is formed between the high-temperature layer, high-temperature cavity and high-temperature manifold inside the radiator and the high-temperature cooling system of the diesel engine;

[0008] An intercooler cooling circulation loop is formed between the intercooler layer, the intercooler cavity and the intercooler manifold inside the radiator and the intercooler cooling system of the diesel engine.

[0009] Furthermore, the cooling device is horizontally installed on the top of the locomotive.

[0010] Furthermore, the radiator is a double-layer flow channel radiator, and the radiator is arranged horizontally to save height space. The height space layout has obvious advantages and the cost is reduced accordingly.

[0011] Furthermore, the two box beams are connected via a collecting box to form a whole.

[0012] Furthermore, the collecting pipe structure is connected to the collecting box through a bent pipe.

[0013] Furthermore, in order to eliminate the original cumbersome water pipe connection, greatly reduce the risk of leakage caused by the pipe connection mechanism, reduce the workload of assembly operators, and improve the manufacturing quality of locomotives, the box beam and the collecting box are connected by a transition assembly.

[0014] Furthermore, the transition assembly includes an upper reinforcing plate and a lower reinforcing plate, wherein the upper reinforcing plate and the lower reinforcing plate are located at the connection between the collecting box and the box beam, and the bent pipe is located between the upper reinforcing plate and the lower reinforcing plate.

[0015] Furthermore, the upper reinforcing plate and the lower reinforcing plate are fan-shaped.

[0016] The beneficial effects of the present invention are as follows: the defects existing in the background technology are solved. 1. Based on the modular and lightweight design concept, the manifold and the radiator bearing structure are integrated to make full use of the wasted space of the original steel structure. The box beams on both sides of the radiator are designed into a three-section structure, which is divided into a radiator installation bearing structure, a manifold structure and a bearing structure of the entire cooling device on the vehicle. In this way, the structure originally only used as a bearing beam is designed into a highly integrated, multi-purpose, and multi-functional fusion box beam. The manifold inlet and outlet of the multi-functional box beam follow the universal and standardized design principles and are designed as interchangeable universal pipes that match the pipeline system.

[0017] 2. The complicated pipe connection at the end of the original radiator is designed into a header box structure. The two ends of the header box are connected to the multifunctional box beam by welding, and the internal pipes are connected. This structure is simple and has high integration. It eliminates the original complicated pipe connection, which can greatly reduce the leakage risk caused by the pipe connection structure, reduce the workload of the assembly operator, and strengthen the strength of the cooling device itself, thereby improving the manufacturing quality of the locomotive;

[0018] 3. The present application eliminates the need for an external collecting pipe and its auxiliary mounting structure, thereby reducing costs. The radiator can be placed flat, saving height space. In addition, the originally wasted space on both sides of the radiator is fully utilized, the structure is compact and highly integrated, the locomotive space utilization rate is high, and the weight of the cooling device is greatly reduced.

DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] Embodiment 1:

[0029] like Figures 1 to 5 A fusion-type lightweight cooling device is shown, which is horizontally mounted on the top of a locomotive and comprises a radiator 1, which is a double-layer flow channel radiator. Box beams 2 are arranged on both sides of the radiator 1. The radiator 1 is mounted on the top of the locomotive through the box beams 2. A header box 3 is arranged at the outlet end of the radiator 1.

[0030] like Figures 4-5 One side of the box beam 2 is a radiator mounting bearing structure 4 for mounting the radiator 1, and the other side is a cooling device mounting bearing structure 6 for mounting the entire cooling device on the locomotive frame. The middle section is a header structure 5 for flowing out the intercooling fluid and the high-temperature fluid. Fluid is a general term for liquids and gases. The header structure 5 on one side is provided with a high-temperature header for flowing out the high-temperature fluid, and the header structure 5 on the other side is provided with an intercooling header for flowing out the intercooling fluid.

[0031] The radiator mounting bearing structure 4, the collecting pipe structure 5 and the cooling device mounting bearing structure 6 are welded and connected, which also strengthens their own strength. At the same time, a number of welding nuts are welded on the radiator mounting bearing structure 4 for fixing the radiator, and a number of welding nuts are welded on the cooling device mounting bearing structure 6 for installing the cooling device; the inner cavity of the collecting box 3 is divided into a high-temperature cavity 9 and an intermediate cooling cavity 10 by a partition 8; the internal pipelines among the radiator 1, the collecting box 3 and the collecting pipe structure 5 are connected.

[0032] An intercooler inlet 11 and a high-temperature inlet 12 are provided at the inlet end of the radiator 1, and the intercooler inlet 11 is slightly lower than the high-temperature inlet 12. A high-temperature outlet 13 and an intercooler outlet 14 are provided at the outlet end of the radiator 1, and the high-temperature outlet 13 is slightly higher than the intercooler outlet 14. A high-temperature layer 17 and an intercooler layer 18 are provided inside the radiator 1. The intercooler inlet 11 is communicated with the intercooler layer 18 inside the radiator 1, the high-temperature inlet 12 is communicated with the internal high-temperature layer 17 of the radiator 1, the high-temperature outlet 13 is communicated with the internal high-temperature layer 17 of the radiator 1, the intercooler outlet 14 is communicated with the internal intercooler layer 18 inside the radiator 1, the high-temperature outlet 13 is communicated with the high-temperature cavity 9 through a pipeline, and the intercooler outlet 14 is communicated with the intercooler cavity 10 through a pipeline.

[0033] The cooling device is installed horizontally on the top of the locomotive, that is, the radiator is placed flat, saving height space.

[0034] The header structure 5 is connected to the header tank 3 via the elbow 7 .

[0035] The box beam 2 and the collecting box 3 are connected by a transition assembly, which includes an upper reinforcing plate 15 and a lower reinforcing plate 16. The upper reinforcing plate 15 and the lower reinforcing plate 16 are located at the connection between the collecting box 3 and the box beam 2, and the bent pipe 7 is located between the upper reinforcing plate 15 and the lower reinforcing plate 16. The upper reinforcing plate 15 and the lower reinforcing plate 16 are fan-shaped, which plays a protective role and is convenient for workers to install and carry.

[0036] Specifically, the radiator mounting bearing structure 4, the cooling device mounting bearing structure 6, and the collector structure 5 are welded to form a box beam module, the collector box 3 is a module, and the radiator 1 is a module. During installation, these four modules are welded and assembled to form a whole, and finally assembled as a module on the top of the locomotive;

[0037] like Figure 1 , Figure 6 As shown, Figure 1 The direction of the middle arrow represents the direction of fluid flow. The inner cavity of the radiator 1 is divided into a high-temperature layer 17 and an intermediate cooling layer 18 by a partition plate 19. The intermediate cooling layer 18 is located below the high-temperature layer 17. A cooling fan 20 is provided below the radiator 1. There are a number of copper fins on the walls around the internal flow channel of the radiator 1. When the cooling fan 20 is working, the wind blows the fins to cool the intermediate cooling fluid in the intermediate cooling layer 18. Since the cooling fan 20 blows from bottom to top, the wind temperature increases to a certain extent at this time, but relative to the high-temperature fluid in the high-temperature layer 17, the wind temperature is still relatively low, thereby cooling the high-temperature fluid in the high-temperature layer 17;

[0038] The high-temperature fluid and the intercooler fluid are two separate cooling circulation systems (i.e., the high-temperature cooling circulation system and the intercooler cooling circulation system). The high-temperature fluid is mainly used to cool the high-heat generating components (such as cylinder liner, etc.) on the diesel engine that are in direct contact with the fuel gas; the intercooler fluid is mainly used to cool the components (such as the intercooler, etc.) on the diesel engine that do not have a particularly high heat generating temperature.

[0039] High-temperature cooling circulation system: The high-temperature fluid for cooling the high-heat generating components in the diesel engine enters the high-temperature layer 17 of the radiator 1 through the high-temperature inlet 12 through the high-temperature pump for cooling. After the heat is dissipated by the cooling fan 20 and the fins, the cooled high-temperature fluid enters the high-temperature cavity 9 from the high-temperature outlet 13, and then flows out through the high-temperature manifold and re-enters the diesel engine to cool the high-heat generating components. The high-heat generating components are cooled, and the heat dissipation and cooling of the high-heat generating components of the diesel engine are completed in this cycle.

[0040] Intercooler cooling circulation system: the intercooler fluid for cooling the components with lower calorific value in the diesel engine enters the intercooler layer 18 of the radiator 1 through the intercooler inlet 11 via the intercooler pump, and the cooling fan at the bottom of the radiator cools the intercooler fluid in the intercooler layer 18. The cooled intercooler fluid enters the intercooler cavity 10 from the intercooler outlet 14, and then flows out through the intercooler manifold and re-enters the diesel engine to cool the components with lower calorific value, thereby cooling the components with lower calorific value, and the cycle is repeated to complete the heat dissipation and cooling of the low-heat generating components of the diesel engine.

[0041] Embodiment 2:

[0042] On the basis of Example 1, the two box beams 2 are connected by a collecting box 3 to form a whole, which becomes a module. When in use, it is directly assembled with the radiator 1 and integrated with the radiator bearing structure. It has high integration and effectively improves work efficiency.

[0043] Among them, each interface in the present application adopts a universal, standardized flange or VICTOLIC pipe clamp structure, which is an interchangeable universal interface that matches the locomotive piping system and has a high degree of universal standardization.

[0044] The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
