[0019] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: an oil cooler that is convenient for disassembling the inner core, including a housing and an inner core assembly;

[0020] The housing includes a cylinder body 1, a first end cover 2 and a second end cover 3. First flanges 4 and second flanges 5 are respectively arranged at both ends of the cylinder body 1. A circular groove 6 is formed on the outer side of the first flange 4. A third flange 7 is arranged on the first end cover 2, and a fourth flange 8 is arranged on the second end cover 3. The first end cover 2 is connected to the first flange 4 of the cylinder body 1 through the third flange 7, and the second end cover 3 is connected to the second flange 5 of the cylinder body 1 through the fourth flange 8. An oil inlet 9 and an oil outlet 10 are respectively arranged on the upper surfaces at both ends of the cylinder body 1. A circulating water inlet 11 is arranged at the outer end of the first end cover 2, and a circulating water outlet 12 is arranged at the outer end of the second end cover 3. Support seats 20 are symmetrically arranged at the bottom of the cylinder body 1 to realize the overall fixed installation;

[0021] The inner core assembly includes a first end plate 13, a second end plate 14, heat exchange tubes 15, lower-opening baffle plates 16 and upper-opening baffle plates 17. Heat exchange tubes 15 are arranged between the first end plate 13 and the second end plate 14. Both ends of the heat exchange tubes 15 penetrate through the first end plate 13 and the second end plate 14 respectively. The heat exchange tubes 15 also pass through the lower-opening baffle plates 16 and the upper-opening baffle plates 17. The heat exchange tubes 15 are connected to the lower-opening baffle plates 16 and the upper-opening baffle plates 17. There are several lower-opening baffle plates 16 and upper-opening baffle plates 17, which are staggeredly distributed between the first end plate 13 and the second end plate 14. The first end plate 13 is arranged in the circular groove 6 of the first flange 4 and is pressed by the third flange 7. The inner diameter of the third flange 7 is smaller than the outer diameter of the first end plate 13. An annular groove is formed on the outer side of the third flange 7, and a first sealing ring 18 is arranged in the annular groove. The first sealing ring 18 is pressed against the first end plate 13. By means of the first sealing ring 18, the sealing performance of the connection between the first end plate 13 and the first flange 4 is ensured, and it is avoided that the circulating water enters the cylinder body 1 from one end of the first flange 4. The outer surface of the second end plate 14 is flush with the outer surface of the second flange 5 and is pressed by the fourth flange 8. The inner diameter of the fourth flange 8 is smaller than the outer diameter of the second end plate 14. An annular groove is formed on the outer side of the fourth flange 8, and a second sealing ring 19 is arranged in the annular groove. The second sealing ring 19 is pressed against the second end plate 14.

[0022] Installation method and working principle: First, drill holes in the baffle plate and open openings at the upper or lower end of the baffle plate to obtain a plurality of lower-opening baffle plates 16 and upper-opening baffle plates 17. Then, pass the heat exchange tubes 15 through the lower-opening baffle plates 16 and upper-opening baffle plates 17. The lower-opening baffle plates 16 and upper-opening baffle plates 17 are arranged at intervals, and a flow cavity is formed between adjacent lower-opening baffle plates 16 and upper-opening baffle plates 17. Then, both ends of all the heat exchange tubes 15 are respectively passed through the first end plate 13 and the second end plate 14. Next, expand the tubes of the first end plate 13 and the second end plate 14 through an expander to complete the assembly of the inner core assembly. Insert the inner core assembly into the cylinder body 1 from one end of the first flange 4 of the cylinder body 1, and insert the first end plate 13 into the circular groove 6 of the first flange 4. At this time, the outer surface of the second end plate 14 is flush with the outer surface of the second flange 5. Finally, put the first sealing ring 18 on the annular groove opened in the third flange 7 of the first end cover 2, and connect the first end cover 2 to the first flange 4 of the cylinder body 1 through the third flange 7. Put the second sealing ring 19 on the annular groove opened in the fourth flange 8 of the second end cover 3, and connect the second end cover 3 to the second flange 5 of the cylinder body 1 through the fourth flange 8 to complete the installation. When in use, the circulating water enters the first end cover 2 from the circulating water inlet 11, then passes through each heat exchange tube 15, and leaves from the circulating water outlet 12 of the second end cover 3. The high-temperature oil liquid enters the cylinder body 1 from the oil inlet 10 on the lower surface of the cylinder body 1. First, it overflows to the next flow cavity in the cylinder body 1 through the flow holes at the top of the upper-opening baffle plate 17, and then enters the next flow cavity through the flow holes at the bottom of the lower-opening baffle plate 16 until the entire cylinder body 1 is filled and then discharged from the oil outlet 9 at the other end. The structure of the present utility model is reasonable. The first flange 4 at one end of the cylinder body 1 is provided with a circular groove 6. The first end plate 13 of the inner core assembly is arranged in the circular groove 6 and is pressed by the third flange 7 of the first end cover 2. At the same time, it is sealed by the first sealing ring 18. The outer end of the second end plate 14 of the inner core assembly is flush with the outer surface of the second flange 5 at the other end of the cylinder body 1 and is pressed by the fourth flange 8 of the second end plate 14. At the same time, it is sealed by the second sealing ring 19. The inner core assembly does not need to be fixed by bolts. When the inner core assembly needs to be replaced or the inside of the cylinder body 1 needs to be cleaned, the inner core assembly is convenient for installation and disassembly, and the convenience is greatly improved.
