Description

Technical Field

[0001] This utility model relates to the field of diesel engine cooling technology, specifically a diesel engine oil cooler. Background Technology

[0002] A diesel engine oil cooler is a heat exchange device whose core function is to transfer the excess heat absorbed by the engine oil during operation to the coolant (water-cooled) or air (air-cooled), so that the oil temperature is kept within the optimal operating range (usually 90°C - 110°C). During long-term use, the internal seals of existing engine oil coolers age faster due to prolonged exposure to high temperatures, thus reducing their sealing performance and causing oil or water leaks, which can affect vehicle driving safety.

[0003] Therefore, we propose a diesel engine oil cooler. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example Please see Figures 1-6 The diagram shows a diesel engine oil cooler, including an oil circulation housing 1, a threaded sealing cap 2 connected to the oil circulation housing 1, a radiator 3 connected below the oil circulation housing 1, a sealing ring 4 between the oil circulation housing 1 and the radiator 3, a dividing ring 8 between the oil circulation housing 1 and the radiator 3, a locking screw 5 with a gap in the middle connected to the radiator 3, an adaptive sealing mechanism 6 inside the locking screw 5, a sealing gasket 7 connected to the adaptive sealing mechanism 6, a water inlet pipe 301 connected to the radiator 3, and a water outlet pipe 302 on one side of the water inlet pipe 301. This invention ensures no leakage between the oil circulation housing and the radiator by using a dividing ring between the oil circulation housing and the radiator, which tightly presses against the sealing ring.

[0018] Furthermore, the adaptive sealing mechanism 6 includes a lower gasket 601, an upper gasket 602, a limiting plate 603, and a spring 604. The lower gasket 601 is fixedly connected to the limiting plate 603, and the spring 604 is provided inside the lower gasket 601. This utility model has an adaptive sealing mechanism inside the locking screw. The adaptive sealing mechanism includes a lower gasket, an upper gasket, a limiting plate, and a spring. The spring tightly presses the upper gasket, the upper gasket tightly adheres to the sealing gasket, and the sealing gasket tightly adheres to the radiator, thereby ensuring no leakage between the radiator and the locking screw.

[0019] Furthermore, a spring base 605 is provided on the surface of the lower pad 601, and a limiting plate 603 is fixedly connected to both sides of the spring base 605.

[0020] Furthermore, the upper gasket 602 is fixedly connected to the centrally symmetrical connecting ear 606, and the connecting ear 606 is slidably connected between the spring base 605 and the limiting plate 603.

[0021] Furthermore, a spring 604 is provided inside the connecting ear 606, and one end of the connecting ear 606 is engaged with the spring base 605.

[0022] Furthermore, the dividing ring 8 includes an inner ring 801 and a pressure plate 802. The inner ring 801 is fixedly connected to the connection between the oil circulation housing 1 and the radiator 3. The pressure plate 802 is fixedly connected to the outer side of the inner ring 801. A sealing ring 4 is provided on the outer side of the inner ring 801, and the sealing ring 4 tightly presses against the pressure plate 802.

[0023] In this solution, the assembly process is as follows: First, install the dividing ring 8: the inner ring 801 is fixedly connected to the oil circulation housing 1 by welding, and then the sealing ring 4 is put into the sealing groove at the bottom of the oil circulation housing 1 to ensure that there is no twisting or folding. And the connection surface with the radiator 3 is initially fixed by the positioning pin, so that the sealing ring 4 is pressed by the inner ring 801 and the pressure plate 802 to form a physical seal; Spring 604 is installed into spring base 605, ensuring that both ends of the spring are aligned with the slots in the base. Lower washer 601 is welded and fixed to limit plate 603. Both sides of spring base 605 are locked to limit plate 603 with bolts to form a stable support structure. Connecting lug 606 of upper washer 602 is inserted into the sliding groove between spring base 605 and limit plate 603 to ensure smooth sliding without jamming. Locking screw 5 is inserted into the gap hole in the middle of radiator 3. Internal self-adaptive sealing mechanism 6 is aligned and pressed with sealing gasket 7. Axial preload is controlled by adjusting the thread of locking screw 5 to ensure that sealing gasket 7 fits the connecting surface without gap.
