[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] As described in the background, the existing automobile engine heat exchange system includes an oil heat exchange module and a waste heat recovery module, wherein the oil heat exchange module and the waste heat recovery module are respectively connected to the cylinder head water jacket, that is, a pipeline connected to the oil heat exchange module and a pipeline connected to the waste heat recovery module are respectively provided in the cylinder head water jacket. This design scheme will increase the complexity of the pipeline layout. In another arrangement, although the oil heat exchange module and the waste heat recovery module adopt a parallel pipeline design scheme, in this design scheme, when the waste heat recovery module is not needed, the coolant will also enter the waste heat recovery module, which will cause the flow in the oil heat exchange module to be diverted and reduced, thereby affecting the heat exchange efficiency of the oil heat exchange module. In order to better solve this problem, the researchers in this application proposed an engine heat exchange system, which connects the waste heat recovery module with the oil heat exchange module and arranges a control valve between the waste heat recovery module and the oil heat exchange module. When the waste heat recovery module is not needed, the control valve disconnects the passage between the waste heat recovery module and the oil heat exchange module, thereby ensuring that the flow of coolant entering the oil heat exchange module is not diverted by the waste heat recovery module, thereby improving the coolant between the oil heat exchange module and the coolant.

[0035] like Figure 1 As shown, Figure 1Schematic diagram of modules in an engine heat exchange system in an embodiment of the present application. In this embodiment, the engine heat exchange system includes: a cylinder head water jacket 110 and a cylinder body water jacket 120, an oil heat exchange module, a waste heat recovery module and a first drive element 500, wherein the coolant can flow inside the cylinder head water jacket 110 and the cylinder body water jacket 120, and cooling channels are provided inside the cylinder head water jacket 110 and the cylinder body water jacket 120, and the cylinder head water jacket 110 and the cylinder body water jacket 120 are used to absorb high temperature heat during the operation of the engine to prevent the engine from overheating; the oil heat exchange module is used to exchange heat with the coolant flowing out of the cylinder head water jacket 110, maintain the appropriate temperature of the engine oil, improve the lubricating effect of the lubricating oil and the working efficiency of the engine; the waste heat recovery module can absorb the heat of the coolant flowing out of the cylinder head water jacket 110, so as to provide heat for, for example, a heater core; the first drive element 500 can ensure that the coolant flows in the engine heat exchange system, and the first drive element 500 can be a water pump. In this embodiment, the researchers intend to connect the oil heat exchange module with the waste heat recovery module and set a control valve 400 between the waste heat recovery module and the oil heat exchange module, so that when the waste heat recovery module is not needed, the channel between the waste heat recovery module and the oil heat exchange module is closed, thereby reducing the diversion of coolant by the waste heat recovery module and improving the heat exchange efficiency of the oil heat exchange module.

[0036] Specifically, the engine heat exchange system includes: a cylinder head water jacket 110 and a cylinder body water jacket 120; an oil heat exchange module is connected to the cylinder head water jacket 110 and the cylinder body water jacket 120 respectively, the coolant flowing out of the cylinder head water jacket 110 is used for heat exchange with the oil flowing in the oil heat exchange module, and the coolant flowing out of the oil heat exchange module flows back to the cylinder body water jacket 120; a waste heat recovery module is connected to the oil heat exchange module, and a control valve 400 is arranged between the waste heat recovery module and the oil heat exchange module, and the control valve 400 is used to control the coolant in the waste heat recovery module to flow back into the oil heat exchange module; a first drive element 500 connects the oil heat exchange module and the cylinder body water jacket 120, and the first drive element 500 is used to transport the coolant flowing out of the oil heat exchange module to the cylinder body water jacket 120.

[0037] In this embodiment, under one of the working modes, the coolant flowing out of the cylinder head water jacket 110 can enter the oil heat exchange module and the waste heat recovery module respectively. It can be understood that the coolant in the cylinder head water jacket 110 will be diverted to enter the oil heat exchange module and the waste heat recovery module, that is, the oil heat exchange module and the waste heat recovery module will have a common pipeline. At this time, the control valve 400 connects the waste heat recovery module with the oil heat exchange module. The coolant entering the oil heat exchange module can absorb the temperature of the oil, thereby cooling the oil. The coolant entering the waste heat recovery module can be heat exchanged by the waste heat recovery module. The coolant flowing out of the waste heat recovery module can flow into the oil heat exchange module through the control valve 400. After the coolant flowing out of the two is converged, it finally enters the cylinder water jacket 120 through the first drive element 500. That is, it can be understood that the coolant after heat exchange in the waste heat recovery module will merge with the coolant after heat exchange in the oil heat exchange module in the oil heat exchange module, and flow back to the cylinder water jacket 120 through the first drive element 500. In another working mode, the control valve 400 closes the channel between the waste heat recovery module and the oil heat exchange module. At this time, the coolant flowing out of the cylinder head water jacket 110 will only enter the oil heat exchange module, and the waste heat recovery module and the oil heat exchange module can be in a cut-off state. In this way, the diversion of the waste heat recovery module can be reduced, ensuring a large flow of coolant entering the oil heat exchange module, thereby improving the heat exchange efficiency of the oil heat exchange module.

[0038] Further, in one embodiment, see Figure 1 As shown, the control valve 400 is a proportional valve, which includes an A1 inlet 410, a B1 outlet 420 and a B2 outlet 430, wherein the B1 outlet 420 is connected to the oil heat exchange module, and the B2 outlet 430 is connected to the waste heat recovery module.

[0039] In this embodiment, when the A1 inlet 410 and the B1 outlet 420 in the control proportional valve are connected, and the A1 inlet 410 and the B2 outlet 430 are closed, the coolant in the waste heat recovery module can enter the oil heat exchange module through the proportional valve; when the A1 inlet 410 and the B1 outlet 420 in the control proportional valve are closed, and the A1 inlet 410 and the B2 outlet 430 are connected, the waste heat recovery module and the oil heat exchange module are in a cut-off state, and the coolant in the waste heat recovery module can be in a self-circulating state or a static state, and the coolant flowing out of the cylinder head water jacket 110 flows through the oil heat exchange module, thereby avoiding the diversion of the waste heat recovery module. In this application, the connection and closing between the inlet and the outlet can be flexibly controlled by the proportional valve.

[0040] In addition, in this embodiment, another reason why the researchers used a proportional valve is that the proportional valve can control the opening of the channel. In some cases, it is necessary for the waste heat recovery module to be partially connected to the oil heat exchange module, and the coolant in the waste heat recovery module can also self-circulate. For example, in winter, the waste heat recovery module can heat the coolant, and the heated coolant can partially flow into the cylinder water jacket 120, thereby warming up the engine. In this case, it can be achieved by adjusting the opening of the A1 inlet 410 and the B1 outlet 420 and the opening between the A1 inlet 410 and the B2 outlet 430; and when the temperature of the coolant flowing out of the cylinder head water jacket 110 gradually increases, the temperature of the coolant in the cylinder head water jacket 110 can provide a heat source for the waste heat recovery module, and the self-heating module in the waste heat recovery module can be turned off. In this way, the flow of coolant from the waste heat recovery module to the oil heat exchange module can be controlled to meet the needs of different scenarios.

[0041] In one embodiment, see Figure 1 As shown, the waste heat recovery module includes an electronic water pump 310, a heater core 320 and a heating module 330. The electronic water pump 310 circulates the coolant entering the waste heat recovery module; the heater core 320 is used to absorb the heat in the coolant entering the waste heat recovery module, and the heating module 330 is used to heat the coolant in the waste heat recovery module.

[0042] In this embodiment, the electronic water pump 310 in the waste heat recovery module can make the coolant flow in the waste heat recovery module; the heater core 320 is used to absorb the heat in the coolant, so as to provide warm air to the passenger compartment; the heating module 330 is used to increase the temperature of the coolant entering the waste heat recovery module. In some scenarios, the temperature of the coolant flowing out of the cylinder head water jacket 110 is low. In this case, the heater core 320 fails to provide warm air to the passenger compartment, so it is necessary to heat the coolant entering the waste heat recovery module through the heating module 330. After heat exchange with the coolant, the heater core 320 can provide warm air to the passenger compartment. In this scenario, there can be a partial opening between the A1 inlet 410 and the B1 outlet 420 in the proportional valve, and between the A1 inlet 410 and the B2 outlet 430. Part of the coolant in the waste heat recovery module can enter the cylinder water jacket 120 to warm up the engine, and part of the coolant can circulate in the waste heat recovery module and provide a heat source for the heater core 320. In other scenarios, when the engine is operating normally, the temperature of the coolant flowing out of the cylinder head water jacket 110 is higher. When the heater core 320 needs to provide warm air to the passenger compartment, the heating module 330 in the waste heat recovery module can be closed, and the area between the A1 inlet 410 and the B1 outlet 420 remains open, and the area between the A1 inlet 410 and the B2 outlet 430 can be closed, and the coolant in the cylinder head water jacket 110 is used to supply heat to the waste heat recovery module.

[0043] In one embodiment, see Figure 1 As shown, the oil heat exchange module includes an oil cooler 210 .

[0044] In this embodiment, in the oil heat exchange module, the oil and the coolant complete heat exchange in the oil cooler 210, and the temperature of the oil is reduced. The oil cooler 210 can be a plate type oil cooler 210 or a shell and tube type oil cooler 210.

[0045] In one embodiment, see Figure 2 As shown, the engine heat exchange system also includes a coolant heat dissipation module, which is connected to the cylinder head water jacket 110 and the first drive element 500 respectively. The coolant flowing out of the cylinder head water jacket 110 enters the coolant heat dissipation module for cooling, and then flows back to the cylinder body water jacket 120 through the first drive element 500.

[0046] In this embodiment, when the engine temperature is high, it is necessary to quickly reduce the temperature of the coolant flowing out of the cylinder head water jacket 110. Therefore, the coolant heat dissipation module can cool the coolant flowing out of the cylinder head water jacket 110. The cooled coolant will flow back to the cylinder body water jacket 120 through the first drive element 500.

[0047] For further information, see Figure 2 As shown, in one embodiment, the coolant heat dissipation module includes a thermostat component 610 and a radiator 620. The thermostat component 610 controls the coolant in the cylinder head water jacket 110 to enter the coolant heat dissipation module, and the radiator 620 is used to cool the coolant entering the coolant heat dissipation module.

[0048] In this embodiment, the coolant flowing into the heat dissipation module can be cooled by the radiator 620, wherein the radiator 620 may be composed of a plurality of thin-walled metal tubes and metal fins. When the high-temperature coolant enters the radiator 620, it can exchange heat with the air through these structures. At the same time, the radiator 620 may also include a fan to improve the heat dissipation effect of the radiator 620. When the thermostat component 610 obtains that the temperature flowing out of the cylinder head water jacket 110 is low, for example, lower than the preset temperature threshold in the thermostat, the temperature of the coolant flowing out of the cylinder head water jacket 110 is low, and it is not necessary to cool the coolant flowing out of the cylinder head water jacket 110 through the radiator 620.

[0049] In one embodiment, see Figure 2 As shown, the engine heat exchange system also includes an exhaust gas recirculation cooler 710, which is connected to the cylinder head water jacket 110 and the first drive element 500 respectively. After the coolant flowing out of the cylinder head water jacket 110 enters the exhaust gas recirculation cooler 710, it flows back to the cylinder body water jacket 120 through the first drive element 500.

[0050] In this embodiment, the coolant flowing out of the cylinder head water jacket 110 can perform heat exchange with the high-temperature exhaust gas inside the exhaust gas recirculation cooler 710. The coolant absorbs the heat of the exhaust gas to reduce the temperature of the exhaust gas.

[0051] In one embodiment, see Figure 2 As shown, the engine heat exchange system further includes an expansion water tank 720 , which is respectively connected to the outlets of the oil heat exchange module, the radiator 620 , and the exhaust gas recirculation cooler 710 .

[0052] In this embodiment, the expansion water tank 720 is respectively connected to the oil heat exchange module, the radiator 620 and the outlet of the exhaust gas recirculation, and the expansion water tank 720 can provide buffering and fluid replenishment functions to these modules.

[0053] In one embodiment, see Figure 2 As shown, the engine heat exchange system is connected to the turbocharger 730, and the turbocharger 730 is respectively connected to the cylinder water jacket 120 and the first drive element 500. After the coolant flowing out of the cylinder water jacket 120 enters the turbocharger 730, it flows back to the cylinder water jacket 120 through the first drive element 500.

[0054] In this embodiment, the coolant flowing out of the cylinder water jacket 120 enters the turbocharger 730. It should be noted that the turbocharger 730 is also provided with cooling channels inside, and the coolant can flow in these cooling channels, thereby absorbing the heat inside the turbocharger 730, reducing the temperature of the turbocharger 730, and ensuring its stable operation under high temperature conditions; the coolant that has absorbed the heat flows out of the turbocharger 730, and then flows back to the cylinder water jacket 120 through the first driving element 500. In this embodiment, the coolant in the cylinder water jacket 120 is used to cool the turbocharger 730. Compared with using the coolant in the cylinder head water jacket 110 to cool the turbocharger 730, the temperature of the coolant in the cylinder water jacket 120 is lower, which can provide a better cooling effect for the turbocharger 730.

[0055] The present application also proposes a car, which includes the above-mentioned engine heat exchange system. After the above-mentioned engine heat exchange system is used in the car, the car can ensure the flow of coolant entering the oil heat exchange module in some working scenes, thereby improving the effect of the oil heat exchange module in cooling the oil.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
