DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0023] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0024] Figure 1 A schematic diagram of a module of a fuel truck cooling system provided by one or more embodiments of this specification. Figure 1 It can be known that the oil truck cooling system includes a main radiator module, an auxiliary radiator module, an engine module, a liquid buffer module, a control module, a coolant pipeline and a valve assembly. Among them, the coolant pipeline is used to connect the main radiator module, the auxiliary radiator module, the engine module and the liquid buffer module. The coolant is arranged in the coolant pipeline. The main radiator module and the auxiliary radiator module are used to cool the coolant flowing through the engine module and the liquid buffer module. When cooling the engine module and the liquid buffer module, the coolant inside the coolant pipeline exchanges heat with the engine module and the liquid buffer module, thereby reducing the temperature of the engine module and the liquid buffer module. After the coolant is heated up, the coolant pipeline is air-cooled through the main radiator module and the auxiliary radiator module, which can take away the heat inside the coolant, thereby reducing the temperature of the coolant and realizing recycling. The valve assembly is arranged in the coolant pipeline, and the coolant pipeline is divided into multiple cooling circuits by opening and closing the valve assembly. The control module is used to obtain the vehicle operating condition of the target vehicle, as well as the current temperature information of the engine module and / or the hydraulic buffer module, and control the opening and closing of the valve assembly, the power of the main radiator module and the auxiliary radiator module according to the vehicle operating condition and the current temperature information.

[0025] Specifically, Figure 2As shown, the cooling circuit includes a first cooling circuit in which the coolant flows to the engine module, the main radiator module, and the engine module; and a second cooling circuit in which the coolant flows to the liquid buffer module, the auxiliary radiator module, and the liquid buffer module; and a third cooling circuit in which the coolant flows to the engine module, the liquid buffer module, the auxiliary radiator module, and the engine module; and a fourth cooling circuit in which the coolant flows to the engine module, the liquid buffer module, the main radiator module, and the engine module; and a fifth cooling circuit in which the coolant flows to the engine module, the auxiliary radiator module, the liquid buffer module, the auxiliary radiator module, and the engine module; and a sixth cooling circuit in which the coolant passes through the engine module, the auxiliary radiator module, the liquid buffer module, the main radiator module, and the engine module. Among them, the first cooling circuit is for the main radiator module to cool down the coolant flowing through the engine module alone, so that the coolant circulates between the main radiator module and the engine. The second cooling circuit is for the auxiliary radiator module to cool down the coolant flowing through the liquid buffer module alone, so that the coolant circulates between the auxiliary radiator module and the liquid buffer module. For the third cooling circuit and the fourth cooling circuit, under normal working conditions, the operating temperature of the engine is lower than that of the liquid buffer, so the coolant after cooling the engine can continue to be used to cool the liquid buffer, and after cooling the liquid buffer, it enters the main radiator module or the auxiliary radiator module, and finally the low-temperature liquid returns to the engine. For the fifth cooling circuit and the sixth cooling circuit, when the cooling demand of the liquid buffer module is large, it is hoped that the temperature of the coolant entering the liquid buffer module is lower. Before entering the liquid buffer module, the auxiliary radiator module can be used to cool the coolant, thereby reducing the temperature of the coolant in advance and improving the cooling efficiency.

[0026] In one embodiment, in order to speed up the flow rate of the coolant, the cooling system can also be provided with a pressurizing component for pressurizing the coolant in the coolant pipeline. At this time, the control module also needs to obtain the flow rate information of the coolant in the target cooling circuit, and control the opening and closing of the valve component, the power of the pressurizing component, the power of the main radiator module and the auxiliary radiator module according to the vehicle operating conditions, flow rate information and current temperature information, so as to select the most appropriate coolant flow rate and reduce the cooling time and energy consumption. It should be noted that in the prior art, most engines have their own pump function for pressurizing the cooling system, and the pressurizing component in the present application can be additionally arranged in each cooling circuit, including at least a first pressurizing component between the engine module and the main radiator module, a second pressurizing component between the liquid buffer module and the auxiliary radiator module, and a third pressurizing component between the engine module and the liquid buffer module.

[0027] Figure 3A flow chart of a method for cooling an oil truck provided for one or more embodiments of the present specification. The process can be executed by a control module in the cooling system, and certain input parameters or intermediate results in the process allow manual intervention and adjustment to help improve accuracy. Specifically, under a test environment, the staff can adjust the preset weights and the numerical values ​​corresponding to the actual opening degrees of different valve components so that the adjustment time and adjustment effect under the test environment meet the test expectations. The implementation of the analysis method involved in the embodiments of the present application can be a control module or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail using the server as an example. It should be noted that the server can be a single device or a system composed of multiple devices, that is, a distributed server, and the present application does not impose any specific restrictions on this.

[0028] like Figure 3 As shown, the embodiment of the present application provides a cooling method for an oil truck, comprising: S301: Obtain the vehicle operating condition of the target vehicle.

[0029] The target vehicle here refers to the vehicle where the cooling system is located, and the vehicle operating condition refers to the working state of the vehicle. Specifically, the vehicle operating condition includes at least one of an unloaded uphill state, an unloaded downhill state, a loaded uphill state, a loaded downhill state, an unloaded flat road state, and a loaded flat road state.

[0030] In one embodiment, when obtaining the vehicle operating condition, it is necessary to obtain the vehicle load value and the vehicle driving slope of the vehicle. The vehicle load value can be measured in real time by an on-board weighing system, and the vehicle driving slope can be measured by a slope sensor. When the vehicle load value is higher than a preset threshold, it can be considered that the vehicle is loaded, and when the vehicle load value is lower than a preset threshold, it can be considered that the vehicle is unloaded. When the vehicle driving slope is higher than a preset threshold, it can be considered that the vehicle is going uphill, and when the vehicle driving slope is lower than a preset threshold, it can be considered that the vehicle is going downhill.

[0031] S302: Acquire current temperature information of the engine module and / or the fluid buffer module.

[0032] When obtaining the current temperature information, if only the engine module needs to be cooled, only the current temperature information corresponding to the engine module can be obtained. Generally, the engine module and the liquid buffer module need to be cooled at the same time. At this time, the current temperature information of the engine module and the liquid buffer module needs to be obtained at the same time. When obtaining the temperature, it can be obtained through the temperature testing equipment connected to the engine module and the liquid buffer module. After obtaining the temperature, it can be determined which module is the module to be cooled based on the current temperature information.

[0033] S303: Controlling the opening and closing of the valve assembly, the power of the pressurizing assembly, the power of the main radiator module, and the power of the auxiliary radiator module according to the vehicle operating condition and the current temperature information.

[0034] After determining the vehicle operating conditions and the module to be cooled, the opening and closing and power of each component can be controlled according to the current temperature information, so as to select a suitable cooling solution to cool the module to be cooled. It is understandable that different vehicle operating conditions have different cooling requirements, which leads to different selectable cooling circuits, so it is necessary to change the current cooling circuit by controlling the valve assembly. At the same time, the flow rate of the coolant can be controlled by adjusting the degree of opening of the valve assembly. Different coolant flow rates can take away different amounts of heat in the module to be cooled, which also leads to different energy consumption required to cool the coolant.

[0035] In one embodiment, when determining the power of the opening and closing pressurizing component of the valve assembly, the power of the main radiator module and the auxiliary radiator module, it is first necessary to determine the ideal input temperature of the module to be cooled based on the vehicle operating conditions. For example, when the vehicle is loaded uphill, the engine power is large and the cooling demand is large, while when the vehicle is loaded downhill, the engine power is small, but the liquid buffer module has a large cooling demand. Therefore, the ideal input temperature of different vehicle operating conditions is different, and the ideal input temperature here refers to the temperature corresponding to the coolant entering the module. Then it is necessary to determine the temperature difference to be adjusted based on the current temperature information of the coolant, the module to be cooled and the ideal input temperature. The temperature difference to be adjusted here refers to the temperature difference of the coolant. After determining the temperature difference to be adjusted, multiple cooling schemes can be generated based on the temperature difference to be adjusted and the vehicle operating conditions. In different cooling schemes, the cooling circuits are different, the opening degree of the valve assembly is different, the power of the pressurizing component is different, and the power of the main radiator module and the auxiliary radiator module is different. Then, the cooling expected values ​​corresponding to the multiple cooling schemes can be determined, and the cooling expected values ​​here are proportional to the cooling efficiency and energy utilization efficiency of the cooling scheme. Finally, based on the expected cooling value, a target cooling scheme can be determined from a variety of cooling schemes, and according to the target cooling scheme, the opening and closing of the valve assembly, the power of the pressurizing assembly, the main radiator module, and the power of the auxiliary radiator module can be controlled.

[0036] Among them, when generating a cooling scheme, the temperature difference to be adjusted, the vehicle load value, and the corresponding values ​​of the vehicle driving slope can be spliced ​​into a feature matrix, where the feature matrix is ​​a three-dimensional matrix, and then the feature matrix can be used as a coordinate to determine the feature points corresponding to the feature matrix in the preset coordinate system. The preset coordinate system here is a three-dimensional coordinate system, and multiple preset standard cooling schemes are preset in the coordinate system. Its format is: when the temperature difference to be adjusted is a℃, the vehicle load value is b kg, and the vehicle driving slope is c°, the cooling scheme is that the valve component opening combination is d, the first power corresponding to the main radiator module is e kW·h, the second power corresponding to the auxiliary radiator module is f kW·h, and the third power corresponding to the pressurizing component is g kW·h. It should be noted that the valve assembly contains multiple valves, and the opening and closing of different valves can change the cooling circuit, and the open valve can also be partially open, thereby controlling the flow rate of the coolant flowing through the valve. Each cooling scheme has different initial conditions. Therefore, the coordinate distance between the characteristic point and each preset standard cooling scheme can be determined in the preset coordinate system. Then, based on the coordinate distance, multiple standard cooling schemes are selected as the cooling schemes corresponding to the temperature difference to be adjusted and the vehicle working conditions. The number of standard cooling schemes selected here can be set in advance by the staff. Then, based on the cooling expected values ​​corresponding to these cooling schemes, the most appropriate target cooling scheme can be selected.

[0037] In one embodiment, when determining the expected cooling value of different cooling schemes, the cooling circuit, the opening degree of the valve assembly, the first power of the main radiator module, the second power of the auxiliary radiator module, and the third power of the pressurizing assembly in the cooling scheme must first be determined; the first temperature to be adjusted corresponding to the engine module and the second temperature to be adjusted corresponding to the liquid buffer module must be determined. Then the expected cooling value corresponding to the cooling scheme can be determined by the following formula:

Specifically, Pick and The larger value between The reserved adjustment time corresponding to the temperature to be adjusted; , , , is the heat exchange coefficient, When the first power corresponding to the main radiator module and the auxiliary radiator module is , and the heat exchange coefficient is The corresponding heat exchange amount when It does not only mean that the heat exchange amount of the main radiator module and the auxiliary radiator module is the same under the same power and the same heat exchange coefficient. When the heat exchange amount of the main radiator module and the auxiliary radiator module is different under the same power and the same heat exchange coefficient, it can be used Represents the heat exchange capacity and power of the main radiator module , heat exchange coefficient The relationship between Represents the heat exchange capacity and power of the auxiliary radiator module , heat exchange coefficient the relationship between; is the first temperature to be adjusted corresponding to the engine module, is the second temperature to be adjusted corresponding to the liquid buffer module; Reduce the temperature of the module to be cooled Temperature heat lost; is the pressure power threshold corresponding to different valve opening degrees, is the initial amplitude. When the third power is greater than the pressurized power threshold, the coolant flow rate will maintain the maximum flow rate and will not increase any more.
