Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically relating to a heat exchanger with an integrated temperature control valve. Background Technology

[0002] Oil radiators are crucial auxiliary components in equipment such as gearboxes, hydraulic systems, and engines. Their core mission is to forcibly cool lubricating oil (or hydraulic oil) and control its temperature within the optimal operating range.

[0003] In the prior art, air-cooled oil radiators are usually used to dissipate heat from the lubricating oil. The core of the air-cooled radiator is equipped with oil channels. The hot lubricating oil flows through these channels, and the fan blows (or draws) air across the fin surface, thereby carrying away the heat and dissipating it into the air to complete the cooling of the lubricating oil.

[0004] Existing air-cooled oil radiators require both hot and cold oil to pass through a core before circulating to the equipment (such as gearboxes, hydraulic systems, engines, etc.). Hot oil is cooled after passing through the core, preventing high-temperature failure and protecting the equipment. However, cold oil passing through the core further lowers the temperature, causing it to become viscous and less fluid. This viscous oil cannot be effectively delivered to the various friction points in the gearbox that require lubrication (such as gear meshing points and bearings), thus affecting the service life of the equipment. Utility Model Content

[0005] This invention provides a heat exchanger with an integrated temperature control valve, which solves the defect in the prior art where the lubricating oil becomes viscous and loses fluidity after being cooled by the radiator and then circulated into the equipment, thus affecting the service life of the equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a heat exchanger with an integrated temperature control valve, comprising:

[0007] A core assembly, the core assembly including a core and cooling grooves that pass through the core and are spaced apart;

[0008] A liquid inlet assembly is disposed at the bottom of the core and is connected to the cooling tank.

[0009] A liquid outlet assembly is disposed on the top of the core and connected to the cooling tank;

[0010] A temperature control component is disposed on one side of the core and is used to connect or block the liquid inlet component and the liquid outlet component.

[0011] Optimally, the core assembly further includes air ducts that pass through the core and are spaced apart, and fins formed between adjacent air ducts, with the cooling grooves passing through the fins.

[0012] Optimally, the liquid inlet assembly includes a lower sealing plate fixed to the bottom of the core and an oil inlet groove that penetrates the lower sealing plate and communicates with the cooling groove.

[0013] Optimally, the liquid outlet assembly includes an upper sealing plate fixed to the top of the core and a first oil discharge trough that passes through the upper sealing plate and communicates with the cooling tank.

[0014] Optimally, the temperature control assembly includes a valve block fixed to the bottom of the core, a temperature control valve installed in the valve block, a side plate fixed to one side of the core, a second oil drain groove passing through the side plate and communicating with the first oil drain groove, and a transition groove opened on the top of the valve block and communicating with the second oil drain groove.

[0015] When the temperature control valve is in the open state, the oil inlet groove is connected to the transition groove;

[0016] When the temperature control valve is in the closed state, the oil inlet groove is blocked from the transition groove.

[0017] Optimally, the temperature control assembly further includes a slot formed on the side of the valve block away from the lower sealing plate, a mounting groove formed in the valve block and communicating with the slot, a through groove formed on the other side of the valve block for communicating with the mounting groove and the oil inlet groove, and a limiting mechanism provided in the slot. The temperature control valve is installed in the mounting groove, the diameter of the slot is larger than the diameter of the mounting groove, and the diameter of the mounting groove is larger than the diameter of the through groove.

[0018] Optimally, the limiting mechanism includes a top cover that snaps into the slot, a sealing groove formed on the outer circumferential surface of the top cover, a sealing ring disposed in the sealing groove, a retaining groove formed on the inner circumferential surface of the slot, and an elastic retaining ring disposed in the retaining groove.

[0019] Optimally, it also includes a fixing plate fixed to the opposite side of the core and the side plate, and an extension plate fixed to the fixing plate and extending away from the core.

[0020] Optimally, it also includes weld holes that penetrate the fixed plate and are spaced apart, and fixing holes that penetrate the extension plate and are spaced apart.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] This utility model integrates a temperature control valve in its heat exchanger. A temperature control component connects or blocks the inlet and outlet components. When the lubricating oil temperature exceeds the valve's set temperature, the valve is closed, allowing the lubricating oil to cool sufficiently within the core before being reintroduced into the equipment. When the lubricating oil temperature is below the valve's set temperature, the valve is open, redistributing the lubricating oil. A portion of the lubricating oil still flows to the core, while the majority bypasses the core and is directly delivered to the equipment. This reduces heat loss, accelerates oil temperature rise, ensures the oil reaches operating temperature quickly, reduces operating resistance and wear, minimizes energy waste, improves lubricating oil fluidity, and ultimately extends the equipment's lifespan.

[0031] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0032] like Figure 1-3The diagram shows the structure of the heat exchanger with integrated temperature control valve of this utility model, which includes a core assembly, a liquid inlet assembly, a liquid outlet assembly, and a temperature control assembly. The liquid inlet assembly is installed at the bottom of the core assembly, the liquid outlet assembly is installed at the top of the core assembly, and the temperature control assembly is located on one side of the core assembly, and can connect or block the liquid inlet assembly and the liquid outlet assembly.

[0033] like Figure 6 The image shown is a cross-sectional view of the core assembly. Figures 1-3 Only the positional relationship of the core components is shown; a schematic diagram of the internal structure of the core components is not shown. A schematic diagram of the internal structure of the core components is shown below. Figure 6 As shown, the core assembly includes a core 3, air ducts 4, fins 5, and a cooling tank 6. Multiple sets of air ducts 4 penetrate the core 3 and are spaced horizontally, with fins 5 forming between adjacent air ducts 4. The cooling tank 6 penetrates the fins 5 vertically. The core 3 is fixed to one side of the fan. The fan blades are rotated by a motor, and air passes through the air ducts 4. When the lubricating oil in the equipment (such as a gearbox) passes through the cooling tank 6, heat exchange is completed, thereby cooling the lubricating oil.

[0034] The liquid inlet assembly includes a lower sealing plate 1, an oil inlet groove 2, and an oil inlet 15. The lower sealing plate 1 is fixed to the bottom of the core 3 by welding. Figure 2 , 3 As shown, the oil inlet groove 2 penetrates the lower sealing plate 1 and is connected to the cooling groove 6 inside the core 3. The oil inlet 15 is located on one side of the oil inlet groove 2, and the lubricating oil in the equipment (such as a gearbox) is introduced into the oil inlet groove 2 through the oil inlet 15.

[0035] The liquid outlet assembly is fixed to the top of the core 3. The liquid outlet assembly includes an upper sealing plate 7, a first oil groove 8, an oil outlet 16, and a plug 17. The upper sealing plate 7 is fixed to the top of the core 3 by welding. The first oil groove 8 passes through the upper sealing plate 7 and is connected to the cooling groove 6 of the core 3. The lubricating oil in the equipment (such as a gearbox) is introduced from the oil inlet groove 2, cooled by the cooling groove 6 of the core 3, and then enters the first oil groove 8.

[0036] Oil outlet 16 is located on one side of the first oil trough 8. Cooled lubricating oil is discharged from oil outlet 16 through the first oil trough 8 and recirculated into equipment (such as a gearbox) via a pipeline for continued use. Plug 17 is located on the other side of the upper sealing plate 7 and is connected to the first oil trough 8. The end opening of the plug 17 has an internal thread and is sealed by a matching external thread plug (not shown in the figure). When cooling of the lubricating oil is required, ensure that the plug is tightened inside the plug 17 to prevent lubricating oil leakage. When equipment maintenance and cleaning are required, the plug can be opened to drain the waste liquid after cleaning.

[0037] The side plate 9 is fixed to one side of the core 3 by welding. The second oil groove 10 passes through the side plate 9 in a vertical direction and is connected to the first oil groove 8. When the temperature control valve 28 is in the open state, part of the lubricating oil in the oil inlet groove 2 passes through the core 3 and enters the first oil groove 8, and the other part enters the first oil groove 8 from the second oil groove 10.

[0038] There are two sets of fasteners, which are fixed to the outer sides of the core 3 and the side plate 9, respectively. The core 3 is fixed to one side of the fan by the fasteners. The fasteners include a fixing plate 11, welding holes 12, an extension plate 13, and fixing holes 14. The fixing plate 11 is fixed to the outer sides of the core 3 and the side plate 9. The welding holes 12 penetrate the fixing plate 11 and are spaced apart in the vertical direction. The inner circumferential surface of the welding holes 12 is the welding position. By setting multiple sets of welding holes 12, the reliability of welding is improved.

[0039] The extension plate 13 is fixed to both sides of the fixed plate 11 and extends away from the core 3. The fixing hole 14 penetrates the extension plate 13. The fixing hole 14 is an oblong hole. The extension plate 13 is fixed to one side of the fan by bolts and nuts (specifically, the extension plate 13 is pressed against the side of the fan frame, the fixing hole 14 is aligned with the through hole on the frame, the fastening bolt is passed through the fixing hole 14 and the through hole on the frame, and the core 3 is fixed by nuts on the other side). By setting the oblong hole, it is easy to adjust during installation and avoids the situation where the bolts cannot be assembled due to misalignment of the machined holes.

[0040] like Figure 4 , 5 As shown, the temperature control component is fixed to one side of the bottom of the core 3 and is used to connect the oil inlet groove 2 and the second oil outlet groove 10. The temperature control component is used to open or block the oil inlet groove 2 and the second oil outlet groove 10. The temperature control component includes a valve block 18, a through groove 19, a mounting groove 20, a retaining groove 21, a top cover 22, a protrusion 23, a sealing groove 24, a sealing ring 25, a retaining groove 26, an elastic retaining ring 27, a temperature control valve 28, a transition groove 29, and a blocking plate 30. The valve block 18 is fixed between the lower sealing plate 1 and the side plate 9 by welding. The retaining groove 21 is opened on the side of the valve block 18 away from the core 3. The retaining groove 21 is used to install a limiting mechanism to limit the installed temperature control valve 28. The mounting groove 20 is opened in the valve block 18 and communicates with the retaining groove 21. The temperature control valve 28 is installed in the mounting groove 20, and the diameter of the retaining groove 21 is larger than the diameter of the mounting groove 20 to engage the limiting mechanism.

[0041] The through groove 19 is opened on the side of the valve block 18 near the core 3, and is used to connect the mounting groove 20 and the oil inlet groove 2 of the lower sealing plate 1. The diameter of the mounting groove 20 is larger than the diameter of the through groove 19, and the spring inside the temperature control valve 28 is limited when the temperature control valve 28 is installed.

[0042] The temperature control valve 28 is installed in the mounting groove 20 and abuts against the shoulder structure formed by the mounting groove 20 and the through groove 19. The top cover 22 is installed in the retaining groove 21 and abuts against the shoulder structure formed by the retaining groove 21 and the mounting groove 20. A sealing groove 24 is formed on the outer peripheral surface of the top cover 22, and a sealing ring 25 is provided in the sealing groove 24. When the top cover 22 is installed in the retaining groove 21, the sealing ring 25 improves the sealing ability between the top cover 22 and the valve block 18, preventing lubricating oil leakage. A protrusion 23 is provided on the side of the top cover 22 away from the temperature control valve 28, which makes it easy for the operator to hold and then insert the top cover 22 into the retaining groove 21, or remove the top cover 22 from the retaining groove 21 for maintenance.

[0043] The retaining groove 26 is annular and is formed on the inner circumferential surface of the slot 21. The elastic retaining ring 27 is installed in the retaining groove 26 to limit the insertion of the top cover 22. The elastic retaining ring 27 facilitates subsequent disassembly and maintenance.

[0044] A transition groove 29 is formed at the top of the valve block 18 to connect the mounting groove 20 and the second oil drain 10 of the side plate 9. When the temperature control valve 28 is in the open state, the oil inlet groove 2, the through groove 19, and the mounting groove 20 are connected to the second oil drain 10 through the transition groove 29. Figure 4 , 5 As shown, the blocking plate 30 is fixed between the valve block 18 and the side plate 9 by welding, and is used to seal the top of the transition groove 29 to prevent lubricating oil leakage.

[0045] Thermostatic valve 28 is installed in mounting groove 20. When thermostatic valve 28 is in the open state, oil inlet groove 2 is connected to transition groove 29. Figure 4 , 5 The diagram shows the state when the temperature control valve 28 is open; when the temperature control valve 28 is closed, the transition groove 29 is blocked by the temperature control valve 28, and the oil inlet groove 2 is separated from the transition groove 29.

[0046] The temperature control valve 28 is a commercially available ACS temperature control valve, which works on the principle of thermal expansion and contraction. When the temperature of the lubricating oil in the equipment (such as a gearbox) is higher than the set temperature of the ACS temperature control valve (i.e., hot oil), the temperature control valve is closed, the transition groove 29 is blocked by the temperature control valve 28, and the lubricating oil in the oil inlet groove 2 can only flow through the cooling groove 6 in the core 3, so that the lubricating oil is fully cooled in the core 1 and discharged through the oil outlet, and then re-entered into the equipment (such as a gearbox) through the pipeline, so that the gear teeth and bearings in the gearbox are fully cooled.

[0047] When the lubricating oil temperature in the equipment (such as a gearbox) is lower than the set temperature of the ACS temperature control valve (i.e., cold oil), the temperature control valve is in the open state. At this time, the oil inlet trough 2 is connected to the transition trough 29. The temperature control valve redistributes the amount of lubricating oil. A portion of the lubricating oil still enters the first oil trough 8 through the core 3, while most of the lubricating oil does not pass through the core 1. It is kept at the original temperature and directly transported to the first oil trough 8 through the transition trough 29 and the second oil trough 10. After mixing in the first oil trough 8, it is discharged from the oil outlet and re-entered into the equipment (such as a gearbox) through the pipeline to lubricate the gear teeth and bearings and other lubricated components in the gearbox. This reduces the wear on the core 1, reduces heat loss, accelerates the rise in oil temperature, ensures that the oil temperature reaches the working temperature quickly, reduces operating resistance and wear, reduces energy waste, improves the fluidity of the lubricating oil, and thus improves the service life of the equipment.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
