[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Implementation Method 1

[0033] like Figures 1 to 5As shown, the present invention provides an integrated oil cooling and oil filter module, comprising a lubricating oil filter 2, a lubricating oil cooler 3 and an integrated seat 1; the integrated seat 1 is provided with a cooling water inlet 101, a cooling water outlet 102, a lubricating oil inlet 103, a lubricating oil outlet 104, at least one oil filter inlet 105 and at least one oil filter outlet 106; the lubricating oil cooler 3 is installed on the integrated seat 1 and is connected with the cooling water inlet 101, the cooling water outlet 102, the lubricating oil inlet and the oil filter inlet 105; the lubricating oil filter 2 is installed on the integrated seat 1 and is connected with the oil filter inlet 105 and the oil filter outlet 106, and the lubricating oil outlet 104 is connected with the oil filter outlet 106 and the engine body.

[0034] The integrated oil cooling and oil filtering module of the present invention integrates the lubricating oil cooler 3 and the lubricating oil filter 2 into one through the integration seat 1, breaking the conventional mindset that the lubricating oil cooler 3 and the lubricating oil filter 2 of the conventional engine are arranged separately, realizing cooling and fine filtering in one, having a simple structure, reducing the occupied space, and lowering the difficulty of installation.

[0035] Specifically, the lubricating oil cooler 3 has an oil inlet end, an oil outlet end, a water inlet end and a water outlet end. The lubricating oil inlet 103 is connected with the oil outlet end of the lubricating oil pump. The lubricating oil in the engine body is recovered by the lubricating oil pump and transported from the oil inlet end of the lubricating oil cooler 3 to the lubricating oil cooler 3 through the lubricating oil inlet 103. The cooling water can enter the lubricating oil cooler 3 from the water inlet end of the lubricating oil cooler 3 through the cooling water inlet 101 of the integrated seat 1 to cool the high-temperature lubricating oil inside. The cooled lubricating oil flows into the integrated seat 1 from the oil outlet end of the lubricating oil cooler 3 and enters the lubricating oil filter 2 from the oil filter inlet 105 for filtration. The cooled and filtered lubricating oil flows into the engine body from the lubricating oil outlet 104 through the oil filter outlet 106.

[0036] In the embodiment of the present invention, the lubricating oil cooler 3 is installed above the integrated seat 1, and the lubricating oil filter is installed below the integrated seat 1, so that the integrated oil cooling and oil filter module mainly occupies space in the height direction, thereby greatly reducing its occupied space in the horizontal direction. Specifically, the lubricating oil cooler 3 is fixed to the top of the integrated seat 1 by multiple bolts.

[0037] There are multiple oil filter inlets 105 and multiple oil filter outlets 106. The oil filter 2 includes multiple oil filter units 201. The multiple oil filter inlets 105 are connected to the multiple oil filter outlets 106 through the multiple oil filter units 201. By setting multiple oil filter units 201, when the filtering efficiency of some of the oil filter units 201 is reduced, the oil can still be filtered through other oil filter units 201, which is beneficial to the stable operation of the engine. Specifically, the oil filter unit 201 includes a filter housing and an oil filter element. The oil filter element is installed in the filter housing. The filter housing is connected to the oil filter inlet 105. The center hole of the oil filter element is connected to the oil filter outlet 106. The oil enters the filter housing from the oil filter inlet 105, flows into the center hole after being filtered by the oil filter element, and the impurities in the oil are intercepted by the oil filter element. Finally, the oil flows into the integrated seat 1 from the oil filter outlet 106.

[0038] After the lubricating oil filter unit 201 has been used for a period of time, there are many impurities attached to the lubricating oil filter element, and the filtering efficiency is reduced and needs to be replaced. In order to facilitate the replacement of the lubricating oil filter unit 201. In the embodiment of the present invention, the integrated seat 1 is provided with a plurality of oil filter joints 107, and the plurality of oil filter joints 107 are respectively connected with the corresponding oil filter inlet 105 and the oil filter outlet 106. The plurality of lubricating oil filter units 201 are installed at the plurality of oil filter joints 107, and the switching valve 108 is installed on the oil filter joint 107. The switching valve 108 is used to control the connection and disconnection between the corresponding lubricating oil filter unit 201 and the oil filter inlet 105 and the oil filter outlet 106. By providing a plurality of oil filter joints 107 to connect the plurality of lubricating oil filter units 201 of the lubricating oil filter 2, and providing a switching valve 108 on the oil filter joint 107, the lubricating oil filter unit 201 can be replaced without stopping the machine.

[0039] In the embodiment of the present invention, the integrated seat 1 is further provided with an oil drain port 109, and the oil drain port 109 is connected with the oil filter outlet 106 and the oil filter outlet 106. The oil drain port 109 is connected with the oil tank, and when the oil pressure of the engine lubricating oil system is relatively high, the lubricating oil in the integrated seat 1 can be returned to the oil tank from the oil drain port 109. Specifically, a pressure regulating valve 4 is installed at the oil drain port 109, and the pressure regulating valve 4 can adjust the flow rate of the lubricating oil leakage according to the oil pressure of the engine lubricating oil system. The present invention integrates the lubricating oil cooler 3, the lubricating oil filter 2 and the pressure regulating valve 4 into one by setting the oil drain port 109 connected with the oil filter outlet 106 and setting the pressure regulating valve 4 at the oil drain port 109, thereby realizing the integration of the three functions of cooling, filtering and pressure regulation.

[0040] In the embodiment of the present invention, an oil return chamber 114 is provided in the integrated seat 1, and the oil return chamber 114 is connected to the oil filter outlet 106, the lubricating oil outlet 104 and the oil drain port 109. An independent cooling oil inlet chamber 112 and a cooling oil outlet chamber 113 are provided in the integrated seat 1, and the cooling oil inlet chamber 112 is connected to the oil inlet end of the lubricating oil cooler 3 and the lubricating oil inlet, and the cooling oil outlet chamber 113 is connected to the oil filter inlet 105 and the oil drain port 109. An independent cooling water inlet chamber 110 and a cooling water outlet chamber 111 are provided in the integrated seat 1, and the cooling water inlet chamber 110 is connected to the cooling water inlet and the water inlet end of the lubricating oil cooler 3, and the cooling water outlet chamber 111 is connected to the water outlet end of the lubricating oil cooler 3 and the cooling water outlet 102.

[0041] Specifically, the integrated seat 1 has a first side and a second side opposite to each other in the length direction, the oil drain port 109 and the cooling water inlet 101 are both located on the first side of the integrated seat 1, and the lubricating oil inlet, the lubricating oil outlet 104 and the cooling water outlet 102 are all located on the second side of the integrated seat 1. When the pressure regulating valve 4 is closed, the oil return chamber 114 and the cooling oil outlet chamber 113 are independently arranged and disconnected from the pressure relief port. When the pressure regulating valve 4 is opened, the oil return chamber 114 and the cooling oil outlet chamber 113 are both connected to the pressure relief port, so that the lubricating oil in the oil return chamber 114 and the cooling oil outlet chamber 113 can be discharged from the oil drain port 109.
