[0002] An oil cooler is an oil cooling device commonly used in hydraulic systems and lubrication systems. By using this device, two fluid media with a certain temperature difference can achieve heat exchange, so as to reduce the oil temperature and ensure the normal operation of the system. According to different heat exchange media, oil coolers can be divided into air-cooled oil coolers and water-cooled oil coolers, which are mainly used to cool hydraulic oil and lubricating oil. Oil coolers are widely used in various industries such as plastic machinery, construction machinery, mining machinery, automobiles, steel, wind power, and aerospace.

[0003] After retrieval, the authorized Chinese patent publication number is CN 217270381 U, which discloses a laminated oil cooler, belonging to the technical field of engine oil cooling. It includes: an oil cooler body, which includes multiple groups of heat exchange fins. The multiple groups of heat exchange fins are stacked and connected from top to bottom, and multiple groups of hot oil channels correspond to and communicate with multiple groups of hot oil circulation areas one by one. Three different hot oils can simultaneously enter the corresponding hot oil circulation areas from the hot oil channels, and are cooled simultaneously without interference, thereby improving the cooling efficiency and further improving the practicability of the entire oil cooler body.

[0027] The interface connection sealing assembly 8 includes a sealing resistance cylinder 801 slidably mounted on the external pipe 2 of the oil cooler, the top end of the sealing resistance cylinder 801 is inserted into the bottom insertion tube 4, the top end of the sealing resistance cylinder 801 is provided with an annular sealing gasket 802, the annular sealing gasket 802 is sleeved on the outside of the external pipe 2 of the oil cooler, the bottom end of the sealing resistance cylinder 801 is connected to the bottom insertion tube 4 by a plurality of set fixing screws 803, the inner wall of the bottom insertion tube 4 is provided with a plurality of inner cavity grooves 804, and a resistance ball 805 is slidably arranged in the inner cavity groove 804.

[0028] A side sliding hole 806 is provided on the inner wall of the inner cavity slide groove 804, and a plurality of external push plates 807 are arranged on the outer side of the bottom insertion tube 4. A connecting rod 808 is slidably inserted in the side sliding hole 806, one end of the connecting rod 808 is connected to the resistance card ball 805, and the other end of the connecting rod 808 is connected to the external push plate 807. A resistance spring 809 is sleeved on the rod body of the connecting rod 808, one end of the resistance spring 809 is connected to the resistance card ball 805, and the other end of the resistance spring 809 is connected to the inner wall of the inner cavity slide groove 804, and a plurality of fixed card grooves 810 are evenly provided on the outer side of the sealing resistance cylinder 801.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that the position limiting abutment frame 6 and the oil cooler external pipe 2 are located on the same vertical line, and the bottom end of the position limiting abutment frame 6 abuts against the top end of the oil cooler external pipe 2.

[0030] The distance that the bottom end of the oil cooler external pipe 2 is inserted into the pipe cover 3 is limited by the limiting abutment frame 6 .

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that the fixed slot 810 is in a curved arc shape that matches with the abutting ball 805 .

[0032] This makes the interference between the interference ball 805 and the fixed groove 810 more consistent.

[0033] Embodiment 4: The difference between this embodiment and Embodiment 1 is that the fixed card slot 810 and the abutting ball 805 are located on the same straight line.

[0034] So that the abutting ball 805 can be pushed by the resilience of the abutting spring 809 to insert the abutting ball 805 into the fixed card slot 810.

[0035] In this embodiment, when the existing stacked oil cooler interface is connected to an external pipeline, a sealing rubber pad is often sleeved at the interface between the pipeline and the oil cooler. However, during repeated rotation and use, the sealing rubber pad is easily worn. After wear, the rubber pad is difficult to achieve a good sealing effect, which easily leads to liquid leakage between the oil cooler interface and the pipeline connection, and is not conducive to the liquid output of the oil cooler.

[0036] In summary, during specific implementation, when the user needs to connect an external pipeline to cool the liquid of the stacked oil cooler main body 1, the user first needs to insert the end of the oil cooler external pipe 2 through the bottom insertion pipe 4 into the pipe head 3. At the same time, an annular sealing pad 802 and a sealing abutting cylinder 801 are sleeved on the oil cooler external pipe 2 first. When the top of the oil cooler external pipe 2 is inserted into the pipe head 3, it will be abutted by the limit abutting frame 6, so that the distance that the oil cooler external pipe 2 is inserted into the pipe head 3 is limited to a certain extent.

[0037] Then, by pushing up the annular sealing pad 802 and the sealing abutting cylinder 801 sleeved on the oil cooler external pipe 2, the annular sealing pad 802 can be moved to the position where the top of the oil cooler external pipe 2 contacts the pipe head 3, and the sealing abutting cylinder 801 can fill the gap reserved between the bottom insertion pipe 4 and the oil cooler external pipe 2, and at the same time provide a supporting force for the annular sealing pad 802. The sealing abutting cylinder 801 is firmly fixed to the bottom insertion pipe 4 by the fixing screw 803.

[0038] When the sealing abutting cylinder 801 is inserted into the bottom insertion pipe 4, the abutting ball 805 retracts into the inner cavity chute 804 under the pulling of the user or the abutment of the sealing abutting cylinder 801. When the sealing abutting cylinder 801 is completely inserted into the bottom insertion pipe 4, the abutting ball 805 will be pushed by the elastic abutment of the abutting spring 809 to insert the abutting ball 805 into the fixed card slot 810, and then abut and fit between the sealing abutting cylinder 801 and the oil cooler external pipe 2 again, so that the gap between the bottom insertion pipe 4 and the oil cooler external pipe 2 can be more firmly sealed under the abutment of the sealing abutting cylinder 801 and the annular sealing pad 802, and the sealing pad in this device will not be easily worn due to rotation, making the connection between the oil cooler external pipe 2 and the pipe head 3 closer, avoiding the situation of easy liquid leakage after the sealing pad is worn, having better sealing performance, and being beneficial to the liquid output and cooling use of the stacked oil cooler main body 1.
