Description

Technical Field

[0001] This utility model relates to the field of cooler technology, specifically to an oil cooler with a filtration function. Background Technology

[0002] Oil coolers are critical thermal management devices widely used in industrial machinery, automotive engineering, energy equipment, and hydraulic systems. Their core function is to transfer heat from lubricating oil or hydraulic fluid to a cooling medium (such as water or air) through heat exchange, thereby controlling the oil temperature within a suitable range and ensuring the stability and reliability of equipment operation. For example, in gearboxes, compressors, wind turbine generators, and electric motors for new energy vehicles, oil coolers effectively prevent problems such as decreased lubrication performance, aging of seals, and sluggish hydraulic system response caused by excessively high oil temperatures, while also extending the service life of the oil and mechanical components.

[0003] However, traditional oil coolers primarily focus on heat exchange performance, but impurities such as metal particles and oxidation products easily mix into the oil during circulation. These impurities adhere to the inside of the oil cooler, which can lead to a decrease in heat exchange efficiency and may also clog the pipes, causing equipment failure.

[0004] Therefore, it is necessary to invent an oil cooler with a filtration function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oil cooler with a filtration function to solve the problems in the above-mentioned technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil cooler with a filtration function, comprising a housing, an oil inlet pipe fixedly connected to one bottom end of the housing, an oil outlet pipe fixedly connected to one top end of the housing, and a filtration assembly disposed directly below the housing. The filtration assembly includes a first tee pipe, a second tee pipe, a main filter, and a secondary filter. The main filter is connected between the main outlet end of the first tee pipe and the main inlet end of the second tee pipe via a flange. The secondary filter is connected between the secondary outlet end of the first tee pipe and the secondary inlet end of the second tee pipe via a flange. The outlet end of the second tee pipe is connected to the oil inlet pipe via a flange. A main valve is installed in the middle of the main outlet end of the first tee pipe and the main inlet end of the second tee pipe. A secondary valve is installed in the middle of the secondary outlet end of the first tee pipe and the secondary inlet end of the second tee pipe.

[0007] The primary and secondary filters are independently controlled via a three-way pipe and valve, supporting online switching, avoiding downtime for maintenance, and improving maintenance efficiency.

[0008] Preferably, when both main valves are open and both secondary valves are closed, the main filter is connected to the lubricating oil circulation system, the secondary filter is in standby mode, and the main filter is capable of filtering the lubricating oil entering the oil cooler.

[0009] When the main filter is in use, the secondary filter is in standby mode and can be switched at any time to ensure continuous operation.

[0010] Preferably, when both main valves are closed and both secondary valves are open, the main filter is in standby mode, and the secondary filter is connected to the lubricating oil circulation system, and the secondary filter is capable of filtering the lubricating oil entering the oil cooler.

[0011] When the main filter becomes clogged or requires maintenance, the secondary filter is immediately connected to prevent impurities from entering the oil cooler due to filtration interruption, thus reducing the risk of equipment downtime.

[0012] Preferably, a first suspension rod and a second suspension rod are fixedly connected to the bottom of the housing, the first tee pipe is installed at the bottom end of the first suspension rod, and the second tee pipe is installed at the bottom end of the second suspension rod.

[0013] The tee pipe is installed vertically by means of a suspension rod, which makes good use of the space under the housing and helps to improve the overall compactness of the device.

[0014] Preferably, one end of the housing is connected to a No. 1 end cap via a flange, and the input end of the No. 1 end cap is fixedly connected to a cooling water supply pipe.

[0015] The cooling water circulation device supplies cooling water to the heat transfer tube group inside the shell through the cooling water supply pipe.

[0016] Preferably, the other end of the housing is connected to a second end cap via a flange, and the output end of the second end cap is fixedly connected to a cooling water return pipe.

[0017] After heat exchange, the cooling water returns to the cooling water circulation system through the cooling water return pipe.

[0018] Preferably, a heat transfer tube assembly is installed inside the shell, and the first end cap and the second end cap respectively abut and limit the two ends of the heat transfer tube assembly.

[0019] As the core heat exchange component, the heat transfer tube bundle, with its densely arranged tubes, increases the heat exchange area and improves the heat transfer efficiency.

[0020] Preferably, the bottom of the housing is fixedly connected to two symmetrically distributed support seats, which support and elevate the housing.

[0021] The support base lifts the housing off the ground, providing installation space for the filter components.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. The filter assembly is integrated below the housing of the oil cooler, and the main filter and secondary filter are connected in parallel to achieve the online filtration function of lubricating oil;

[0024] 2. The dual-filter design supports a redundancy mechanism where the main filter is in operation and the secondary filter is on standby. When the main filter is clogged or under maintenance, the system can switch to the secondary filter without stopping the machine, ensuring continuous operation of the equipment and significantly improving system reliability.

[0033] In one aspect of this embodiment, when both main valves 10 are open and both secondary valves 11 are closed, the main filter 6 is connected to the lubricating oil circulation system, and the secondary filter 7 is in standby mode. The main filter 6 can filter the lubricating oil entering the oil cooler. When both main valves 10 are closed and both secondary valves 11 are open, the main filter 6 is in standby mode, and the secondary filter 7 is connected to the lubricating oil circulation system. The secondary filter 7 can filter the lubricating oil entering the oil cooler. A first suspension rod 8 and a second suspension rod 9 are fixedly connected to the bottom of the housing 1. A first tee pipe 4 is installed on the first suspension rod 8. At the bottom of the suspension rod 8, the No. 2 tee pipe 5 is installed at the bottom of the No. 2 suspension rod 9. One end of the housing 1 is connected to the No. 1 end cap 12 through a flange. The input end of the No. 1 end cap 12 is fixedly connected to the cooling water supply pipe 13.

[0035] Working principle of this utility model:

[0036] Refer to the instruction manual appendix Figure 1-4When using this utility model, firstly, connect the input end of the No. 1 three-way pipe 4 and the oil output pipe 3 to the circulation pipe of the lubrication system to ensure that the lubricating oil can circulate in the shell 1. Connect the cooling water supply pipe 13 and the cooling water return pipe 15 to the cooling water circulation device. Continuously supply cooling water to the heat transfer tube group 16 inside the shell 1 through the cooling water circulation device. Use the flow of cooling water to cool down the lubricating oil inside the shell 1 so as to maintain the oil temperature within a reasonable range.

[0037] Before the lubricating oil enters the oil cooler through the oil inlet pipe 2, open the two main valves 10 and close the two secondary valves 11 to connect the main filter 6 to the lubricating oil circulation system. At this time, the secondary filter 7 is in standby mode, and the main filter 6 can filter the lubricating oil entering the oil cooler.

[0038] When the main filter 6 needs maintenance or becomes clogged, close both main valves 10 and open both secondary valves 11 to connect the secondary filter 7 to the lubricating oil circulation system. The secondary filter 7 filters the lubricating oil, while the main filter 6 is isolated from the lubricating oil circulation system, making it convenient to maintain or replace the main filter 6.
