Description

Technical Field

[0001] This invention relates to the field of cooler technology, and more specifically to a lubricating oil cooler that is easy to clean. Background Technology

[0002] In fields such as machinery and equipment, power energy, marine propulsion, and industrial manufacturing, lubricating oil coolers, as core components of lubrication systems, play a crucial role in controlling lubricating oil temperature and ensuring stable equipment operation. Their working principle involves transferring heat from the high-temperature lubricating oil to a cooling medium (such as water or air) through heat exchange, thereby maintaining the oil temperature within a reasonable range (typically 40-65℃). This prevents equipment wear, efficiency reduction, or even malfunctions caused by lubricating oil deteriorating due to high-temperature oxidation or insufficient fluidity at low temperatures.

[0003] Although traditional tubular oil coolers have advantages in heat exchange efficiency, structural strength, and cost, they still have some drawbacks in practical use, which limit their ease of maintenance and long-term reliability. For example, traditional oil coolers mostly use a fixed tube sheet structure. After long-term operation, minerals and impurities in the cooling water easily deposit on the inner wall of the tubes, forming a fouling layer, which leads to a decrease in heat exchange efficiency. Cleaning the inside of the pipes requires first removing the oil cooler from the cooling water system, and then flushing the inside of the pipes with a cleaning agent. This process is cumbersome and complicated, not only time-consuming and labor-intensive, but also increases equipment downtime and maintenance costs.

[0004] Therefore, it is necessary to invent a convenient and easy-to-clean lubricating oil cooler to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an easy-to-clean lubricating oil cooler to solve the problems in the above-mentioned technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a convenient and easy-to-clean lubricating oil cooler, comprising a shell, a first end cap, a second end cap, a first tee pipe, and a second tee pipe. The first end cap and the second end cap are respectively installed at both ends of the shell. A first ball valve is installed in the middle of the first tee pipe. The three ports of the first tee pipe are a cooling water supply end, a cleaning agent supply end, and a medium input end, respectively. The medium input end is fixedly connected to the input end of the first end cap. The cooling water supply end and the cleaning agent supply end are both perpendicular to the medium input end. A first right-angle channel is opened inside the valve core of the first ball valve. One end of the first right-angle channel is connected to the cooling water supply end, and the other end of the first right-angle channel is connected to the medium input end.

[0007] A ball valve is installed in the middle of the No. 2 three-way pipe. The three ports of the No. 2 three-way pipe are the cooling water discharge end, the cleaning agent discharge end, and the medium output end. The medium output end is fixedly connected to the output end of the No. 2 end cap. The cooling water discharge end and the cleaning agent discharge end are both perpendicular to the medium output end. The valve core of the No. 2 ball valve has a No. 2 right-angle channel. One end of the No. 2 right-angle channel is connected to the cooling water discharge end, and the other end of the No. 2 right-angle channel is connected to the medium output end.

[0008] By designing a structure that includes a No. 1 tee pipe, a No. 2 tee pipe, and a corresponding ball valve, flexible switching between cooling water and cleaning agent channels is achieved.

[0009] Preferably, after the valve core of the No. 1 ball valve is rotated 90 degrees counterclockwise, one end of the No. 1 right-angle channel is connected to the cleaning agent supply end, and the other end of the No. 1 right-angle channel is connected to the medium input end.

[0010] After the valve core of ball valve No. 1 is rotated 90 degrees counterclockwise, it can connect the No. 1 right-angle channel with the cleaning agent supply end, thereby allowing the cleaning agent to directly enter the heat transfer tube assembly for cleaning.

[0011] Preferably, after the valve core of the second ball valve is rotated 90 degrees clockwise, one end of the second right-angle channel is connected to the cleaning agent discharge end, and the other end of the second right-angle channel is connected to the medium output end.

[0012] After the valve core of ball valve No. 2 is rotated 90 degrees clockwise, it can connect the No. 2 right-angle channel with the cleaning agent discharge end, thus facilitating the discharge of cleaning waste liquid and detached scale from the heat transfer tube assembly.

[0013] Preferably, a heat transfer tube assembly is installed inside the shell, and a limiting ring is fixedly connected to the end of the first end cap and the second end cap facing the shell. Both limiting rings extend into the shell and abut against the two ends of the heat transfer tube assembly, respectively.

[0014] The heat transfer tube assembly is installed inside the shell and fixedly connected to the end cap by a limiting ring. This design not only ensures the stability of the heat transfer tube assembly, but also facilitates disassembly and replacement when needed.

[0015] Preferably, an oil inlet is fixedly connected to the bottom of the housing near the second end cap, and an oil outlet is fixedly connected to the top of the housing near the first end cap.

[0016] The bottom and top of the housing are respectively provided with an oil inlet and an oil outlet. This layout meets the circulation requirements of the lubrication system and facilitates the inflow and outflow of lubricating oil in the cooler.

[0017] Preferably, the bottom of the housing is fixedly connected to two support seats, which are symmetrically distributed about the housing.

[0018] The design of two symmetrically distributed support bases enhances the overall stability of the cooler.

[0019] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0020] By designing No. 1 and No. 2 tee pipes and installing No. 1 and No. 2 ball valves respectively, the channels for cooling water and cleaning agent can be switched without disassembling the lubricating oil cooler during the cleaning process. Specifically, when cleaning is required, simply rotating the valve cores of No. 1 and No. 2 ball valves allows the cleaning agent to enter the heat transfer tube assembly through the cleaning agent supply end, decompose the scale on the inner wall of the tubes, and discharge the waste liquid through the cleaning agent discharge end. This process does not require removing the lubricating oil cooler from the system, greatly simplifying the cleaning steps and improving cleaning efficiency. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] This invention provides, for example Figure 1-5The lubricating oil cooler shown includes a housing 1, a first end cap 2, a second end cap 3, a first tee pipe 4, and a second tee pipe 5. The first end cap 2 and the second end cap 3 are respectively installed at both ends of the housing 1. A first ball valve 6 is installed in the middle of the first tee pipe 4. The three ports of the first tee pipe 4 are a cooling water supply end 7, a cleaning agent supply end 8, and a medium input end 9. The medium input end 9 is fixedly connected to the input end of the first end cap 2. The cooling water supply end 7 and the cleaning agent supply end 8 are both perpendicular to the medium input end 9. A first right-angle channel 10 is opened inside the valve core of the first ball valve 6. One end of the first right-angle channel 10 is connected to the cooling water supply end 7, and the other end of the first right-angle channel 10 is connected to the medium input end 9.

[0030] A No. 2 ball valve 11 is installed in the middle of the No. 2 three-way pipe 5. The three ports of the No. 2 three-way pipe 5 are the cooling water discharge end 12, the cleaning agent discharge end 13, and the medium output end 14. The medium output end 14 is fixedly connected to the output end of the No. 2 end cap 3. The cooling water discharge end 12 and the cleaning agent discharge end 13 are both perpendicular to the medium output end 14. The valve core of the No. 2 ball valve 11 has a No. 2 right-angle channel 15. One end of the No. 2 right-angle channel 15 is connected to the cooling water discharge end 12, and the other end of the No. 2 right-angle channel 15 is connected to the medium output end 14.

[0031] In one aspect of this embodiment, after the valve core of ball valve 6 is rotated 90 degrees counterclockwise, one end of right-angle channel 10 is connected to cleaning agent supply end 8, and the other end of right-angle channel 10 is connected to medium input end 9. After the valve core of ball valve 11 is rotated 90 degrees clockwise, one end of right-angle channel 15 is connected to cleaning agent discharge end 13, and the other end of right-angle channel 15 is connected to medium output end 14. Heat transfer tube assembly 16 is installed inside the housing 1. Limiting rings 17 are fixedly connected to the ends of end cap 2 and end cap 3 facing the housing 1. Both limiting rings 17 extend into the housing 1 and abut against the two ends of heat transfer tube assembly 16 respectively. Lubricating oil input end 18 is fixedly connected to the bottom of housing 1 near end cap 3. Lubricating oil output end 19 is fixedly connected to the top of housing 1 near end cap 2. Two support seats 20 are fixedly connected to the bottom of housing 1. The two support seats 20 are symmetrically distributed about housing 1.

[0032] The shell 1, end cap 2, end cap 3 and heat transfer tube assembly 16 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0033] Working principle of this invention:

[0034] Refer to the instruction manual appendix Figure 1-5When using this invention, firstly, during normal use, connect the lubricating oil inlet 18 and lubricating oil outlet 19 to the circulation pipe of the lubrication system to ensure that the lubricating oil can circulate in the cooler. Connect the cooling water supply end 7 and cooling water outlet 12 to the cooling water circulation device. Continuously supply cooling water to the heat transfer tube group 16 inside the shell through the cooling water circulation device. Use the flow of cooling water to cool the lubricating oil inside the shell 1 to maintain the oil temperature within a reasonable range.

[0035] After prolonged use, scale can easily form on the inner wall of the heat transfer tube assembly 16 due to the deposition of minerals and impurities in the cooling water, which leads to a decrease in heat exchange efficiency. Therefore, it is necessary to clean it regularly.

[0036] During cleaning, first rotate the valve core of ball valve 6 counterclockwise by 90 degrees, so that one end of right-angle channel 10 is connected to the cleaning agent supply end 8 and the other end is connected to the medium input end 9; at the same time, rotate the valve core of ball valve 11 clockwise by 90 degrees, so that one end of right-angle channel 15 is connected to the cleaning agent discharge end 13 and the other end is connected to the medium output end 14. Cleaning agent is continuously introduced into heat transfer tube assembly 16 through cleaning agent supply end 8. The cleaning agent flows in heat transfer tube assembly 16 and decomposes the scale. The reacted cleaning agent carries the detached scale out through cleaning agent discharge end 13 until the scale is completely removed.

[0037] Before cleaning is finished, clean water is continuously introduced into the heat transfer tube assembly 16 through the cleaning agent supply end 8 to rinse the inside of the heat transfer tube assembly 16 until the water discharged through the cleaning agent discharge end 13 remains clear, ensuring that the cleaning agent is completely discharged.

[0038] After cleaning, the valve cores of ball valve 6 and ball valve 11 are reset to their original positions, so that the heat transfer tube assembly 16 is reconnected to the cooling water circulation device, restoring the cooler to normal working condition.

[0039] The entire cleaning process does not require frequent disassembly and reassembly of the lubricating oil cooler. The flow of cooling water and cleaning agent can be switched simply by adjusting the position of the ball valve core, which saves time and effort and helps reduce equipment downtime and maintenance costs.
