Description

Technical Field

[0001] The utility model relates to the technical field of power equipment cooling, in particular to a power propulsion oil cooling device. Background Art

[0002] In the field of modern automotive engineering, automobile engines, as the core power source, have continuously evolved in the direction of higher power, stronger torque and lower fuel consumption. The heat generated by the engine during operation rises sharply. The engine oil plays an indispensable dual role inside the engine. On the one hand, the engine oil forms a lubricating film between the various moving parts, reducing friction and wear, and ensuring smooth operation of the engine. On the other hand, the engine oil circulates inside the engine, absorbing and taking away a large amount of heat generated by component friction, combustion, etc., playing a key role in assisting the heat dissipation of the engine.

[0003] During the operation of a car engine, the oil cooler plays a vital role. It is responsible for cooling the oil that has absorbed the heat of the engine to maintain the normal operating temperature of the engine. During the circulation process, the oil will carry various impurities, such as metal debris, colloids, etc., so it is necessary to set a filter in the oil cooler to filter out impurities.

[0004] The traditional filtering method is to install a filter inside the oil inlet for filtering. However, the existing filter structure is usually circular. During long-term use, due to the continuous impact of the engine oil, the structural stability of the circular filter is poor and it is easy to be damaged. At the same time, due to its structural characteristics, the circular filter will produce a large flow resistance when the engine oil flows through it. As the use time increases, the accumulation of impurities on the filter will further aggravate this resistance. The large flow resistance will not only reduce the circulation speed of the engine oil, but also reduce the circulation cooling efficiency of the engine oil, which makes it impossible for the heat of the engine to be taken away in time, resulting in an increase in the engine operating temperature, affecting the engine performance and reliability.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution: a power propulsion oil cooling device, comprising;

[0029] The shell 2 is made of high-strength aluminum alloy material; a core is provided inside it;

[0030] The oil inlet 3 and the oil outlet 4 are located at both ends of the housing 2, the oil inlet 3 is connected to the engine oil outlet, and the oil outlet 4 is connected to the engine oil inlet;

[0031] The filter screen 14 is detachably arranged in the oil inlet 3. The filter screen 14 includes a lower filter portion 141 arranged inside the oil inlet 3. The top surface of the lower filter portion 141 is connected to a middle filter portion 142 extending vertically upward. The top surface of the middle filter portion 142 is connected to an upper filter portion 143 extending radially along the oil inlet 3.

[0032] Specifically, the oil inlet 3 and the oil outlet 4 determine the inlet and outlet paths of the engine oil, allowing the engine oil to circulate between the engine and the oil cooling device. The filter 14 is located in the oil inlet 3. Its special structural design, the lower filter part 141, the middle filter part 142 and the upper filter part 143 work together to filter the engine oil from different directions, effectively intercepting metal debris, colloid and other impurities in the engine oil to prevent them from entering the core and causing blockage or damage. The multi-section structure of the filter 14 improves the filtering effect, can better protect the internal components of the oil cooling device, extend the service life of the device, ensure the purity of the engine oil, and thus maintain the stable operation of the engine lubrication and cooling system.

[0033] See Figure Figure 4 and Figure 5 An escape opening 146 is formed through the lower filter portion 141 , and an external thread 147 is provided on the outer wall of the lower filter portion 141 , and an internal thread matching the external thread 147 is provided on the inner wall of the oil inlet 3 .

[0034] Specifically, the avoidance port 146 of the lower filter portion 141 can adjust the flow rate and flow velocity distribution of the engine oil entering the filter to a certain extent, reduce local impact, and the external thread 147 cooperates with the internal thread of the inner wall of the oil inlet 3 to realize the detachable installation of the filter 14. When the filter 14 needs to be cleaned or replaced, it can be easily unscrewed and removed; this threaded connection method facilitates the maintenance of the filter 14, and can promptly clean or replace a clogged or damaged filter, thereby ensuring the continued effectiveness of the filtering function and reducing maintenance costs and time.

[0035] See Figure 4 Clamping claws 144 are provided on the top and bottom surfaces of the middle filter portion 142 , and clamping grooves 145 for the clamping claws 144 to be clamped into are provided on the surfaces where the lower filter portion 141 , the upper filter portion 143 and the middle filter portion 142 are in contact.

[0036] Specifically, the claws 144 of the middle filter part 142 cooperate with the slots 145 of the lower filter part 141 and the upper filter part 143 to tightly connect the filter parts to form a stable overall structure. Under the impact of engine oil and long-term vibration, the filter parts can be prevented from loosening or separating, thereby ensuring the integrity of the filtering process; the structural stability of the filter 14 is enhanced, its reliability in complex working environments is improved, and the risk of filtration failure caused by loose filter structure is reduced. At the same time, it is also convenient for disassembly.

[0037] See Figure 5, the filter 14 is Z-shaped as a whole, the outer diameter of the filter 14 is adapted to the inner diameter of the oil inlet 3, the filter 14 is a ferromagnetic material.

[0038] Specifically, the filter 14 is Z-shaped as a whole. This shape can disperse the impact force of the engine oil, reduce the pressure on a single part, and reduce the damage to the filter caused by the impact of the engine oil. Its outer diameter is adapted to the inner diameter of the oil inlet 3 to ensure good sealing and filtering effects, so that the engine oil can only enter the device after being filtered through the filter 14. Since it is made of ferromagnetic material, it can be conveniently used to utilize magnetic absorption to collect metal impurities adsorbed on the filter, which is convenient for cleaning; the impact resistance of the filter 14 is improved, and the service life is extended. The good sealing adaptability prevents engine oil leakage and the entry of unfiltered engine oil. The ferromagnetic material characteristics are conducive to impurity cleaning, further improving the maintenance convenience of the filtration system.

[0039] See Figure 1 The core is composed of multiple layers of flat copper tubes and heat dissipation fins stacked alternately. The flat copper tubes constitute the oil circulation channel, and the heat dissipation fins adopt a wavy design and fit tightly to the outer surface of the flat copper tubes.

[0040] See Figure 1 and Figure 2 , it also includes an outer frame 1, a shell 2 is installed on the front end surface of the outer frame 1, a water-cooling circulation pipe 5 is arranged inside the outer frame 1, the head end of the water-cooling circulation pipe 5 is connected to a water inlet 6, the end of the water-cooling circulation pipe 5 is connected to a water outlet 7, the water inlet 6 is connected to the car coolant outlet, and the water outlet 7 is connected to the car coolant inlet; a vent 11 is opened on the rear side of the outer frame 1, a hollow cover 10 is fixedly installed on the outside of the vent 11, a drive motor 12 is fixedly installed on the hollow cover 10, and a driving end of the drive motor 12 extends to the inside of the vent 11 and is fixedly connected to a heat dissipation fan blade 13.

[0041] See Figure 1 The left and right sides of the lower part of the outer frame 1 are fixed with mounting seats 8 by bolts, and the mounting seats 8 are provided with a plurality of vertically arranged mounting holes 9 at equal intervals.

[0042] Specifically, the outer frame 1 provides installation space for the water-cooling circulation pipe 5 and together with the shell 2 constitutes a complete device structure. The water-cooling circulation pipe 5 is introduced with automobile coolant through the water inlet 6. The coolant circulates in the pipe, absorbs the heat conducted from the shell 2 and the core, and then flows out through the water outlet 7, carrying the heat out of the device, thereby providing cooling assistance for the entire oil cooling device.

[0043] The water-cooling cycle further enhances the heat dissipation capacity of the oil cooling system, especially in high-load or high-temperature environments. It can better control the oil temperature, prevent engine overheating, and improve engine stability and durability under extreme operating conditions.

[0044] Vent 11 provides an air flow channel for cooling fan blades 13. Drive motor 12 drives cooling fan blades 13 to rotate, allowing external cold air to enter outer frame 1 through vent 11. This cold air flows through the surfaces of components such as water-cooling circulation pipe 5 and housing 2, removing heat and accelerating heat dissipation. Hollow cover 10 acts as a protective shield, preventing foreign matter from entering vent 11 and damaging the fan blades. The combination of air and water cooling creates a composite heat dissipation method, significantly improving heat dissipation efficiency and rapidly reducing device temperature. This ensures the continued stable operation of the oil cooling system and reduces the risk of engine failure due to insufficient heat dissipation.

[0045] Working principle:

[0046] The hot oil generated by the engine enters the housing 2 through the oil inlet 3 connected to the engine oil outlet. Inside the oil inlet 3, the detachable filter 14 begins to function. It has a special Z-shaped structure, including a lower filter part 141, a middle filter part 142 and an upper filter part 143, which gradually filters the oil from different directions. The avoidance port 146 of the lower filter part 141 can adjust the oil flow rate and flow rate distribution. The various parts cooperate with the claws 144 and the grooves 145 to ensure structural stability. The external thread 147 facilitates disassembly and maintenance, thereby effectively filtering out metal debris, colloid and other impurities in the oil, ensuring that the oil entering the device is relatively pure.

[0047] The filtered engine oil enters the core composed of multiple layers of flat copper tubes and heat dissipation fins alternately stacked, and the engine oil flows in the flat copper tubes. Since the flat copper tubes increase the contact area between the engine oil and the tube wall, the heat of the engine oil can be efficiently transferred to the tube wall, and then the heat is transferred to the wavy heat dissipation fins tightly fitted on the outer surface of the flat copper tube. At the same time, the water-cooling circulation pipe 5 arranged inside the outer frame 1 introduces the automobile coolant through the water inlet 6. The coolant circulates in the water-cooling circulation pipe 5, absorbs the heat conducted from the core and the shell 2, and then flows out through the water outlet 7 to take away the heat. In addition, the drive motor 12 at the air vent 11 drives the heat dissipation fan blades 13 to rotate, so that external cold air enters from the vent 11 and flows through the surfaces of components such as the water-cooling circulation pipe 5 and the shell 2. The combination of air cooling and water cooling further accelerates the heat dissipation and realizes efficient cooling of the engine oil. The cooled engine oil flows out from the oil outlet 4 connected to the engine oil inlet and returns to the engine for lubrication and heat dissipation, and this cycle repeats.

[0048] Through the multiple vertically arranged mounting holes 9 on the mounting bases 8 on the left and right sides of the lower part of the outer frame 1, it is fixed to the engine compartment of the car or a corresponding appropriate position with bolts. The mounting height and angle can be flexibly adjusted according to actual conditions to ensure that the device is firmly installed and in a suitable position to ensure its normal operation.

[0049] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
