Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, specifically to a lubricating oil heat exchange device. Background Technology

[0002] Oil heat exchangers are key components in the lubrication systems of various mechanical equipment and are widely used in fields such as shipbuilding, power, and heavy machinery. Their main function is to control the working temperature of the lubricating oil through heat exchange to ensure the normal operation of the equipment.

[0003] Existing patent document CN217979393U discloses a compact and efficient lubricating oil cooling device, comprising a volute, an impeller, a core, and an end cover. The impeller is disposed inside the volute, and the core is connected to the air inlet end face of the volute. The core is connected to the end cover. Lubricating oil from the helicopter main gearbox flows into the end cover through a lubricating oil channel inside the volute. A temperature-sensing valve in the end cover determines whether the lubricating oil flows into the core or flows out directly through a bypass pipe (no longer entering the core for lubricating oil heat exchange). This utility model has a compact structure and high heat exchange efficiency, ensuring that the lubricating oil cooling device achieves maximum heat exchange performance within a limited space. Simultaneously, the design of a bypass temperature-sensing valve controls the lubricating oil at different temperatures, improving the radiator's lifespan and reliability.

[0004] Although the device has many beneficial effects, the following problems still exist: The heat exchange core (core) and the outer shell (volute, end cover) of the device are fixedly connected, usually by welding or bolting. Once the internal flow channels are scaled and blocked due to lubricating oil impurities or oxidation, it is difficult to clean and maintain quickly and thoroughly. The machine must be stopped and the entire device disassembled, which seriously affects the continuous operation efficiency of the equipment. Secondly, the device has a complex internal structure and many dead corners in the oil flow path, which can easily lead to the deposition of impurities and sludge. This not only reduces heat exchange efficiency but may also exacerbate flow channel blockage, increasing system operation risks and maintenance costs. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved: To address the issue that the heat exchange core (core) and outer shell (volute, end cover) of the device are fixedly connected, they are usually fastened by welding or bolts. Once the internal flow channels become scaled or blocked due to lubricating oil impurities or oxidation, it is difficult to clean and maintain them quickly and thoroughly. The machine must be stopped and the entire device disassembled, which seriously affects the continuous operation efficiency of the equipment. Secondly, the device has a complex internal structure and many dead corners in the oil flow path, which can easily lead to the deposition of impurities and sludge. This not only reduces the heat exchange efficiency but may also aggravate the blockage of the flow channel, increasing the risk of system operation and maintenance costs. Therefore, this utility model was proposed.

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural schematic diagram of an embodiment of a lubricating oil heat exchange device, including: Please see Figures 1-5 The lubricating oil heat exchange device of this embodiment includes: a plurality of flow dividers 1, and a heat exchange mechanism 100 is provided between the plurality of flow dividers 1 to exchange heat on the lubricating oil; Multiple flanges 2, some of which are located at the upper end of the heat exchange mechanism 100, and the other part of which are located at the lower end of the heat exchange mechanism 100; Multiple disassembly mechanisms 200 are provided. Some disassembly mechanisms 200 are located between the heat exchange mechanism 100 and multiple flow dividers 1, while other disassembly mechanisms 200 are located between the heat exchange mechanism 100 and multiple flanges 2, which can disassemble and maintain the heat exchange mechanism 100.

[0024] It is worth noting that, specifically, for heat exchange, the heat exchange mechanism 100 includes: multiple baffles 101, which are welded between multiple flow dividers 1. Multiple flow channels 102 are formed between the partitions 101; Multiple seals a103 are welded to the side wall of partition 101; Multiple seals b104, some of which are welded to the top of the partition 101, and the other part of which are welded to the bottom of the partition 101; Multiple heat exchange tanks 105 are formed between multiple seals b104.

[0025] Next, for sealing purposes, specifically, the partition 101, seal a103 and seal b104 are made of nitrile rubber to prevent oil leakage during the heat exchange process.

[0026] Meanwhile, for disassembly and maintenance, specifically, the disassembly mechanism 200 includes: multiple disassembly plates a201, one end of which is welded to the inner wall of the diversion plate 1; Multiple dovetail grooves a202 are formed at the other end of the disassembly plate a201; Multiple dovetail plates a203 are welded to the outer wall of the seal a103, and the dovetail groove a202 and the dovetail plate a203 are connected by tenon and mortise joints. Multiple disassembly plates b204 are welded to the inside of flange 2 at one end; Multiple dovetail grooves b205 are formed at the other end of the disassembly plate b204; Multiple dovetail plates b206 are welded to the outer wall of the seal b104, and the dovetail groove b205 and the dovetail plate b206 are connected by tenon and mortise joints.

[0027] Furthermore, to prevent the partition 101 from hitting the underwear, specifically, the length of the disassembly plate b204 is greater than the length of the partition 101, which can prevent the partition 101 from shifting.

[0028] It is worth noting that, specifically, in order to allow lubricating oil to enter and exit, an oil inlet 11 is installed on the outer side of part of the distributor plate 1, and an oil outlet 12 is installed on the outer side of another part of the distributor plate 1.

[0029] Finally, for installation and use, specifically, the flange 2 includes a mounting plate 21, and the outer end of the mounting plate 21 has multiple mounting ports 22.

[0030] Combination Figures 1-5 The specific usage process of the lubricating oil heat exchange device according to this embodiment is as follows: 1. Based on actual usage, fix this device to the unit base using the mounting plate 21 and mounting port 22 on flange 2. Connect the system's hot oil pipeline to the oil inlet 11 on the distributor plate 1, and connect the inlet and outlet pipelines of the cooling medium, such as cold water, to the corresponding interfaces on the upper and lower flanges 2.

[0031] 2. Hot oil enters through inlet 11, is distributed by distributor 1, and flows into heat exchange mechanism 100, which consists of multiple baffles 101 and seals 103 and 104. Cooling medium flows in from the lower flange, passes through the flow channel formed by heat exchange tank 105 and guide channel 102, and exchanges heat with the oil in a counter-current or cross-flow manner. The cooled oil flows out from outlet 12, and the cooled medium, after absorbing heat, flows out from upper flange.

[0032] 3: When the heat exchange mechanism 100 needs maintenance, by sliding the disassembly plate a201 and disassembly plate b204 outward, the dovetail grooves a202 and b205 are disengaged from the dovetail plate a203 welded to the seal a103 and the dovetail plate b206 welded to the seal b104, and the entire heat exchange mechanism 100 can be extracted from the main body of the device for cleaning or replacement.
