Description

Technical Field

[0001] The utility model belongs to the technical field of oil coolers, and particularly relates to a leak-proof oil cooler. Background Art

[0002] The oil cooler is a transmission oil cooler, which is used to dissipate the excess heat of the transmission, so that the transmission oil temperature is in the best working state, thereby improving the fuel economy of the whole vehicle and increasing the transmission efficiency.

[0003] When the existing oil cooler is connected to the oil pipe, it mainly relies on the sealing gasket to achieve the sealing effect. This sealing method is relatively single, and after the sealing gasket is used for a certain period of time, the phenomenon of aging will occur, resulting in a decline in the sealing effect, thus causing oil leakage at the connection of the oil cooler. Therefore, there are great limitations in actual use and there is room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a leak-proof oil cooler to solve the problem of poor sealing effect and oil leakage of the existing oil cooler proposed in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A leak-proof oil cooler, including a body, at the top of which two pipes are connected. One is a gasoline inlet and the other is a gasoline outlet; it also includes a leak-proof component, which is composed of a main seal and an auxiliary seal. The main seal is arranged at the inner and outer walls of the pipe, and the middle parts of the main seals at the inner and outer walls bulge towards the inside and outside of the pipe respectively. During connection, the bulging areas of the main seal can be used to connect with the external oil pipe. At the same time, since the main seals are arranged on both the inside and outside, the connection method of the oil pipe is improved; the auxiliary seal is arranged above and below the main seal. The auxiliary seal at the upper position overlaps the end faces of the pipe and the main seals at the inner and outer walls. During the installation of the oil pipe, it can facilitate the direct contact between the oil pipe and the main seal, avoiding loosening caused by excessive installation gaps and squeezing the connection between the main seal and the pipe. The auxiliary seal at the lower position is sleeved on the pipe and is located at the connection position between the pipe and the body to achieve the sealing of the end of the oil pipe after installation.

[0006] Preferably, inner annular grooves and outer annular grooves are respectively opened downward at the inner wall and outer wall at the top end of the pipe; the main seal includes an inner sealing airbag adhered in the inner annular groove and an outer sealing airbag adhered in the outer annular groove, and the connection with the oil pipe is realized through the inner sealing airbag and the outer sealing airbag.

[0007] Preferably, the auxiliary seal includes a gasket arranged below the outer sealing airbag, and there is a gap between the gasket and the outer annular groove. The auxiliary seal also includes a sealing ring arranged above the inner sealing airbag and the outer sealing airbag in the outer annular groove.

[0008] Preferably, a thread is provided in the area between the bottom of the pipeline and the outer ring groove, and the thread is threadedly connected to the inner wall of the external oil pipe.

[0009] Preferably, a reinforcing frame is further sleeved outside the body. The reinforcing frame is formed by welding four steel columns. The overall strength of the body can be improved through the reinforcing frame to achieve the anti-deformation ability.

[0010] Preferably, rubber blocks are adhered to the upper and lower end faces inside the reinforcing frame. The rubber blocks abut against the upper and lower end faces of the body, so as to realize the flexible contact limit between the body and the reinforcing frame. After being impacted, the impact force transmitted from the reinforcing frame to the body can be reduced through the flexible connection.

[0011] Preferably, the front and rear side surfaces inside the reinforcing frame do not contact the body to avoid affecting the normal heat dissipation of the body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the designed anti-leakage component, in cooperation with the existing conventional sealing gasket, the effect of multiple seals is achieved, thereby avoiding the phenomenon of oil leakage in the oil cooler. At the same time, the anti-leakage component has a simple structure, is convenient for processing and production, has high practicability, and improves the insufficient sealing performance of the existing oil cooler.
