[0040] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will describe the specific implementation manners of the present invention with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other accompanying drawings can also be obtained based on these drawings, and other implementation manners can also be obtained.

[0041] See Figure 1 , this embodiment discloses a structure of an oil cooler assembly, which is installed on one side of the cylinder block A of the engine. The oil cooler assembly B includes a base 1 and a cooler body 2. The base 1 is used to be fixed to the engine cylinder block A, the cooler body 2 is fixed on the base 1, and at the same time, an oil filter 3 is installed on the base 1.

[0042] See Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the base 1 includes a base body 11 and a cover plate 12. The base body 11 includes a water chamber portion 111, an oil passage portion 112, and a mounting surface 113. The mounting surface 113 is used for mounting on the engine block A. The cover plate 12 covers the water chamber portion 111 and is located on the opposite side of the mounting surface 113. The water chamber portion 111 is located between the cover plate 12 and the mounting surface 113. In this embodiment, the cover plate 12 is detachably provided on the opening side of the water chamber portion 111, and a sealing gasket is provided between the cover plate 12 and the base body 11. In other embodiments, the cover plate 12 may also be integrally formed with the base body 11.

[0043] A partition plate 114 is provided in the water chamber portion 111 to divide the water chamber portion 111 into an inlet water chamber 1111 and an outlet water chamber 1112. A communication port 115 communicating the inlet water chamber 1111 and the outlet water chamber 1112 is formed on the partition plate 114. The setting of the communication port 115 ensures the normalization of the cooling water pressure in the engine body, avoids the situation where the cooling water cannot pass through the oil cooler in time, resulting in the water pressure in the engine body being higher than the normal water pressure, and avoids the occurrence of throttling phenomenon.

[0044] See Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , a base water inlet 1131, a base water outlet 1132, a base oil inlet 1133, and a base oil outlet 1134 are formed on the mounting surface 113. A cover plate water inlet 121, a cover plate water outlet 122, a cover plate oil inlet 123, a cover plate oil outlet 124, a water intake 125, and a water drain 126 are formed on the cover plate 12. Among them, the base water inlet 1131 and the cover plate water inlet 121 are both communicated with the inlet water chamber 1111, and the base water outlet 1132 and the cover plate water outlet 122 are both communicated with the outlet water chamber 1112. At the same time, the base water inlet 1131 and the base water outlet 1132 are also communicated with the water jacket in the cylinder block a. The water intake 125 and the water drain 126 are both communicated with the outlet water chamber 1112, and both the water drain 126 and the water intake 125 are located at the bottom of the outlet water chamber 1112.

[0045] The cooler body 2 is fixed to the cover plate 12 and is located on the opposite side of the side where the base body 11 is located. The internal water channel of the cooler body 2 is communicated with both the cover plate water inlet 121 and the cover plate water outlet 122. The internal oil channel of the cooler body 2 is communicated with both the cover plate oil inlet 123 and the cover plate oil outlet 124. The water drain 126 and the water intake 125 are both located below the cooler body 2. A water intake joint 4 communicated therewith is provided on the water intake 125, and a water drain faucet 5 communicated therewith is provided on the water drain 126. The water intake joint 4 and the water drain faucet 5 are both fixed to the cover plate 12.

[0046] See Figure 1 and Figure 2, in this embodiment, the width of the cover plate 12 is greater than the width of the cooler body 2. After the cooler body 2 is fixed on the cover plate 12, the part of the cover plate 12 below the cooler body 2 cooperates with the base body to form a water supply area, that is, the water supply area is located at the bottom of the water outlet cavity 1112. This water supply area is located below the cooler body 2 and at the lowest point of the engine coolant circulation system at the same time. The water intake joint 4 and the water drain faucet 5 are both integrated here, and the water draining efficiency is high. The drain port 126 is set here. The coolant in the cooler assembly and part of the coolant in the engine body are discharged through the water drain faucet 5, which can prevent the coolant from freezing in winter and damaging the engine. The water intake port 125 is set here and is connected to the EGR cooler through the water intake joint 4. Without changing the mold parts, it provides a cooling source for the EGR cooler. Because this water supply area is located in the first half of the engine coolant circulation system, the water flow is large and the water temperature is low. In other embodiments, according to the specific installation equipment, the water intake joint 4 set here is not limited to connecting the EGR cooler, and can also provide a better cooling source for the whole vehicle supporting heat dissipation, etc. At the same time, since this water supply area is large and the cost of laser cutting the cover plate is low, the angles and positions of water intake and drainage can be arranged arbitrarily according to the needs of the whole vehicle and the engine.

[0047] See Figures 6 to 10 , the oil passage part 112 includes a filter mounting seat 1121 for installing the oil filter 3 and an engine oil passage 1122 connecting the filter mounting seat 1121 and the cooler body 2. The filter mounting seat 1121 is located below the water cavity part 111. The engine oil passage 1122 is connected to the base oil inlet 1133, the base oil outlet 1134, the cover plate oil inlet 123, and the cover plate oil outlet 124. At the same time, the cover plate oil inlet 123 and the cover plate oil outlet 124 also connect the engine oil passage 1122 with the internal oil passage of the cooler body.

[0048] The engine oil passage 1122 includes a first oil passage a connected to the base oil inlet 1133, a second oil passage b connecting the first oil passage a and the cover plate oil inlet 123, a third oil passage c connected to the cover plate oil outlet 124, a fourth oil passage d connected to the third oil passage c, a fifth oil passage e for connecting the fourth flow passage d and the engine oil filter inlet, and a sixth oil passage f for connecting the engine oil filter outlet and the base oil outlet 1134. The fifth oil passage e and the sixth oil passage f are both arranged on the filter mounting seat 1121. There is a second oil passage outlet 1123 connected to the cover plate oil inlet 123 on the second oil passage b, and a third oil passage inlet 1124 connected to the cover plate oil outlet 124 on the third oil passage c.

[0049] The first oil passage a is communicated with the third oil passage c, and a check valve 6 is arranged in the first oil passage a to separate and seal the first oil passage a and the third oil passage c. A pressure regulating valve 7 is arranged at the end of the fourth oil passage d, and a return port 1135 is formed at the installation surface 113 corresponding to the pressure regulating valve 7. The return port 1135 is communicated with the pressure regulating valve 7 and the oil pan of the engine (not shown in the figure). The cooperation between the return port 1135 and the pressure regulating valve 7 is used to control the pressure of the engine oil passage 1122, and further control the pressure of the main oil passage in the engine body, so that excessive engine oil can flow into the oil pan through the return port 1135. Reinforcing ribs 1136 are distributed on the installation surface 113 in a crisscross pattern to improve the strength of the base body 11 itself.

[0050] It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention falling within the scope of the appended claims and their equivalent technical solutions.
