[0039] Example 1

[0040] See Figures 1 to 6As shown, the engine cooling system provided in this application includes an engine block 101 and an oil cooler 102. The main function of the oil cooler 102 is to regulate the operating temperature of the engine oil, ensuring that it remains within the ideal operating range. Engine oil generates a large amount of heat during engine operation; if it is not cooled in time, the oil viscosity will decrease, affecting lubrication. The oil cooler 102 cools the engine oil, maintaining its viscosity stability, thereby ensuring good lubrication of all engine components, extending service life, and improving transmission efficiency.

[0041] When installing the oil cooler 102, it is fitted snugly to the surface of the engine block 101. Specifically, the oil cooler 102 is provided with a first water inlet 103, a first oil inlet 104, and a first oil outlet 105. The engine block 101 is provided with a second water outlet 106, a second oil outlet 107, and a second oil inlet 108. The first water inlet 103 and the second water outlet 106 are directly connected, the first oil inlet 104 and the second oil outlet 107 are directly connected, and the first oil outlet 105 and the second oil inlet 108 are directly connected. Cooling water in the engine block 101 can enter the oil cooler 102 from the second water outlet 106 via the first water inlet 103, and engine oil in the engine block 101 can enter the oil cooler 102 from the second oil outlet 107 via the first oil inlet 104. Within the oil cooler 102, heat exchange occurs between the engine oil and the coolant, allowing the coolant temperature to be used to control the oil temperature. When the oil temperature is high, it can be cooled by the coolant. When the engine is started, the oil absorbs heat from the coolant, causing its temperature to rise rapidly. The cooled oil in the oil cooler 102 flows back into the engine block 101 from the first oil outlet 105 via the second oil inlet 108.

[0042] The engine cooling system provided in this application, by attaching the oil cooler 102 to the surface of the engine block 101 and directly connecting the engine block 101 and the oil cooler 102, eliminates the need for the rubber hose and metal connector connecting the engine block 101 and the oil cooler 102. This reduces costs and avoids the risk of the rubber hose melting. The overall layout of the device is simpler and more compact, reducing the space occupied and facilitating the layout of the engine in the engine compartment.

[0043] In an optional embodiment, the engine block 101 is provided with a first connecting groove, the bottom of which is connected to the water outlet channel of the engine block 101, and the opening of the first connecting groove forms a second water outlet 106; the engine block 101 is provided with a second connecting groove, the bottom of which is connected to the oil outlet channel of the engine block 101, and the opening of the second connecting groove forms a second oil outlet 107; the engine block 101 is provided with a third connecting groove, the bottom of which is connected to the oil inlet channel of the engine block 101, and the opening of the third connecting groove forms a second oil inlet 108.

[0044] In this embodiment, in the prior art, the oil cooler 102 draws water from cylinder 3 of the engine. Since the oil cooler 102 is far from the water inlet, a rubber hose is needed to connect the two. This application places the oil cooler 102 at the location of cylinder 2 of the engine, where a water outlet channel, an oil outlet channel, and an oil inlet channel are provided. This application provides a first connecting groove connected to the water outlet channel, a second connecting groove connected to the oil outlet channel, and a third connecting groove connected to the oil inlet channel. This allows a second water outlet 106, a second oil outlet 107, and a second oil inlet 108 to be formed on the surface of the engine block 101. The oil cooler 102 can cover the second water outlet 106, the second oil outlet 107, and the second oil inlet 108, thus achieving communication between the water and oil passages of the two components.

[0045] In an optional embodiment, a first sealing ring 109 is provided between the first water inlet 103 and the second water outlet 106; the first water inlet 103 is located within the groove opening of the first connecting groove, and the first sealing ring 109 surrounds the circumference of the groove opening of the first connecting groove; a second sealing ring 110 is provided between the first oil inlet 104 and the second oil outlet 107; the first oil inlet 104 is located within the groove opening of the second connecting groove, and the second sealing ring 110 surrounds the circumference of the groove opening of the second connecting groove; a third sealing ring 111 is provided between the first oil outlet 105 and the second oil inlet 108; the first oil outlet 105 is located within the groove opening of the third connecting groove, and the first sealing ring 109 is installed in the circumference of the groove opening of the third connecting groove. This increases the sealing performance at the connection opening between the engine block 101 and the oil cooler 102, preventing water and oil leakage between the engine block 101 and the oil cooler 102. Specifically, the first sealing ring 109, the second sealing ring 110, and the third sealing ring 111 are all fluororubber sealing rings.

[0046] In this embodiment, the first connecting groove is an oblong groove, and a first mounting groove 112 is provided circumferentially around the opening of the first connecting groove. The first sealing ring 109 is oblong and is installed in the first mounting groove 112. The second connecting groove is a circular groove, and a second mounting groove 113 is provided circumferentially around the opening of the first connecting groove. The second sealing ring 110 is circular and is installed in the second mounting groove 113. The third connecting groove is an oblong groove, and a third mounting groove 114 is provided circumferentially around the opening of the third connecting groove. The third sealing ring 111 is oblong and is installed in the third mounting groove 114.

[0047] In this embodiment, due to the limitations of the installation position and size of the oil cooler 102 and the engine block 101, it cannot be guaranteed that the first water inlet 103 and the second water outlet 106, the first oil inlet 104 and the second oil outlet 107, and the first oil outlet 105 and the second oil inlet 108 can be aligned and matched. Figure 3 and Figure 4 The first connecting groove shown is a vertically arranged waist-shaped groove, which allows the upper water outlet channel to connect with the lower first water inlet 103. Similarly, the third connecting groove is a vertically arranged waist-shaped groove, which allows the lower oil inlet channel to connect with the upper first oil outlet 105. Since the oil outlet channel is opposite to the first oil inlet 104, the second connecting groove can be a conventional circular groove.

[0048] Furthermore, based on the shapes of the first connecting groove, the second connecting groove, and the third connecting groove, corresponding first mounting grooves 112, second mounting grooves 113, and third mounting grooves 114 with matching shapes are opened around each of them to achieve the installation and fixation of the first sealing ring 109, the second sealing ring 110, and the third sealing ring 111, thereby ensuring reliable sealing of the connecting position.

[0049] In an optional embodiment, the engine cooling system further includes an EGR cooler 115; the oil cooler 102 is provided with a first outlet, the EGR cooler 115 is provided with a third inlet, and a connecting pipe 116 is provided between the third inlet and the first outlet.

[0050] In this embodiment, the EGR cooler 115 is part of the Exhaust Gas Recirculation (EGR) system, and its core function is to reduce the temperature of the exhaust gas entering the intake manifold by introducing coolant. Because the exhaust gas produced by the engine is very hot, its direct entry into the intake manifold would result in an excessively high air-fuel mixture temperature, leading to engine knocking and vibration, increased fuel consumption, and higher emissions. By reducing the exhaust gas temperature, the EGR cooler 115 reduces nitrogen oxide emissions, helping the engine maintain optimal operating conditions and meeting environmental requirements.

[0051] Specifically, the cooling water in the engine block 101 can enter the oil cooler 102 from the second outlet 106 via the first inlet 103 of the oil cooler 102. The cooling water in the oil cooler 102 can also enter the EGR cooler 115 from the first outlet via the third inlet of the EGR cooler 115 to cool the exhaust gas.

[0052] In this optional embodiment, the EGR cooler 115 is spaced apart from the engine block 101, and the oil cooler 102 is disposed between the EGR cooler 115 and the engine block 101. The EGR cooler 115 and the oil cooler 102 are stacked vertically, which can make reasonable use of the space below the EGR and make the structure more compact.

The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.

[0055] See Figure 5 and Figure 6 As shown, in an optional embodiment, the oil cooler 102 includes a cooler body 117 and a mounting plate 118. The cooler body 117 is the main component for cooling the engine oil and consists of a top plate, a top fin, fins, a fin, and a bottom fin. The mounting plate 118 is used to mount the cooler body 117 to the engine block 101. Specifically, one side of the mounting plate 118 is connected to the bottom of the cooler body 117, and the other side of the mounting plate 118 is fitted to the surface of the engine block 101. The bottom of the cooler body 117 is provided with a first water inlet 103, a first oil inlet 104, and a first oil outlet 105. The mounting plate 118 is provided with three corresponding connecting holes to allow coolant and engine oil to flow. The top of the cooler body 117 is provided with a first water outlet to allow coolant to flow into the EGR cooler 115.

[0056] In an optional embodiment, the mounting plate 118 has multiple connecting holes 119 circumferentially arranged, and the engine cylinder block 101 has correspondingly multiple mounting holes. Connectors are provided between the connecting holes 119 and the mounting holes to connect the mounting plate 118 and the engine cylinder block 101. Figure 2 and Figure 5 As shown, five connecting holes 119 are provided circumferentially on the mounting plate 118, and five corresponding mounting holes are provided on the engine block 101. Connection can be made via five M6 fasteners from the hexagonal flange face. The number and position of the connecting holes 119 and mounting holes can be set according to actual conditions, and are not limited to the five shown in the figure.

[0057] In an optional embodiment, the oil cooler 102 includes a connecting pipe 120. One end of the connecting pipe 120 is connected to a first outlet; specifically, the connecting pipe 120 is a metal pipe welded to the first outlet. The other end of the connecting pipe 120 is connected to a connecting pipe 116. The connecting pipe 116 is a rubber tube, and the connecting pipe 120 is connected to the connecting pipe 116 for support. The rubber connecting pipe 116 is easy to install and can be bent to avoid other structures.
