Description

Technical Field

[0001] The utility model belongs to the technical field of engine testing, and in particular relates to an engine oil cooling system. Background Art

[0002] Demands for automobile reliability, safety, and environmental friendliness are constantly increasing. As the heart of a car, the engine's technical level directly impacts performance indicators such as power, economy, and emissions, and engine failures are also the most frequent. Comprehensive engine performance testing is the primary means of determining the technical condition of an engine and a crucial component of vehicle inspection and maintenance. Consequently, engine performance testing is gaining increasing attention. Traditional comprehensive engine performance testing systems primarily test engine performance under specific steady-state conditions. However, in actual operation, vehicles often experience transient conditions such as starting, acceleration, and deceleration. Speed ​​and torque vary over time, and mixture formation and combustion constantly change. This results in significant differences in engine power, economy, emissions, and other performance indicators compared to those under typical steady-state conditions.

[0003] The traditional oil constant temperature system can only meet the requirements of stable engine operating conditions, but it is difficult to meet the requirements of constant oil temperature under engine testing conditions. For this purpose, an oil cooling system has been developed. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides an oil cooling system to solve the above-mentioned problems in the background technology.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An oil cooling system includes a control module, a circulation pump, a heat exchanger, a filter, a collection unit, and several control valves, wherein one end of the circulation pump is provided with an inlet pipeline connected to the engine oil outlet, and the other end of the circulation pump is connected to the heat exchanger, the filter, and the collection unit in sequence through pipelines. The output end of the collection unit is provided with an outlet pipeline connected to the engine oil inlet, and the control valve is provided on the outlet pipeline, thereby forming a complete oil circulation circuit. The control module is electrically connected to the circulation pump, the heat exchanger, the filter, the collection unit, and the several control valves.

[0007] Furthermore, the acquisition unit includes a flow acquisition unit and a temperature acquisition unit, which are used to monitor the flow and temperature of the oil circuit of the engine to be tested.

[0008] Furthermore, the control module is used to process the data collected by the collection unit and issue instructions to drive and control the control valve.

[0009] Furthermore, it also includes a water inlet pipeline and a water outlet pipeline, and the water inlet pipeline is connected to the filter, the heat exchanger, the collection unit and the water outlet pipeline in sequence.

[0010] Furthermore, the control module includes a controller, and the controller is connected to the flow acquisition unit, the temperature acquisition unit and the control valve respectively.

[0011] Furthermore, the control valve is an electric control valve. A cabinet is also included, in which the oil cooling system is installed, and the bottom of the cabinet is provided with movable casters.

[0012] Compared to existing technologies, this new system offers the following advantages: When the system starts, the circulating water pump begins operating, and the engine oil undergoes heat exchange within the heat exchanger. The temperature change after heat exchange is related to the flow rate and temperature of the exchange medium (water) flowing through the heat exchanger: the greater the water flow rate, the lower the temperature drop. The flow rate of water through the heat exchanger is controlled by a temperature control instrument. When the system detects that the engine oil temperature is below a set point, the valve is closed; otherwise, it is opened. When the temperature reaches the set point, the valve position remains unchanged, thus achieving automatic temperature control. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1:

[0022] like Figs. 1-2 Specifically, the present invention provides an oil cooling system, comprising a control module, a circulation pump 2, a heat exchanger 3, a filter 4, a collection unit 5, and a plurality of control valves, wherein one end of the circulation pump 2 is provided with an inlet pipe 1 connected to the engine oil outlet, and the other end of the circulation pump 2 is connected to the heat exchanger 3, the filter 4, and the collection unit 5 in sequence through pipes, and the output end of the collection unit 5 is provided with an outlet pipe 6 connected to the engine oil inlet, and the outlet pipe 6 is provided with a control valve, thereby forming a complete oil circulation circuit, and the control module is electrically connected to the circulation pump 2, the heat exchanger 3, the filter 4, the collection unit 5, and the plurality of control valves.

[0023] The acquisition unit 5 includes a flow acquisition unit and a temperature acquisition unit, which are used to monitor the flow and temperature of the oil circuit of the engine to be tested.

[0024] The control module is used to process the data collected by the collection unit 5 and issue instructions to drive and control the control valve.

[0025] It also includes a water inlet pipeline 8 and a water outlet pipeline 9. The water inlet pipeline 8 is connected to the filter 4, the heat exchanger 3, the collection unit 5 and the water outlet pipeline 9 in sequence.

[0026] The control module includes a controller and a cabinet 7. The oil cooling system is installed in cabinet 7, and casters 71 are provided at the bottom of cabinet 7. The controller is connected to the flow acquisition unit, the temperature acquisition unit, and the control valve. The controller's high-precision PID control algorithm dynamically adjusts exhaust back pressure in real time, tracking engine operating conditions and rapidly adjusting the flow rate of refrigerated water to regulate the oil temperature. The engine oil undergoes heat exchange in the heat exchanger. The temperature change after heat exchange is related to the flow rate and temperature of the water flowing through the heat exchanger: a greater water flow rate results in a lower temperature drop. The water flow rate through the heat exchanger is controlled by a temperature control instrument. When the system detects that the engine oil temperature is below the set point, the valve is closed; otherwise, it is opened. When the temperature reaches the set point, the valve position remains unchanged, thus achieving automatic temperature control. The electric proportional valve requires a separate 24V AC power supply with a power of 200W to drive the electric valve.

Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
