[0025] The present invention is further described in detail below in conjunction with specific implementations and in conjunction with the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0026] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0027] An engine oil pan cooling system, such as Figures 1 to 3As shown, the engine 02 is placed in a semi-sealed box 01, and the box 01 is provided with an air inlet 03 and an air outlet 04 in the length direction, the air inlet 03 is close to the air inlet side of the engine 02, and the air outlet 04 is close to the exhaust side of the engine 02, including an oil pan 05, heat dissipation ribs 07 and an exhaust fan 06; the oil pan 05 is arranged at the bottom of the engine 02, and is used to store the engine oil of the engine 02 and dissipate the heat of the engine oil; a plurality of heat dissipation ribs 07 are arranged on the outer side of the bottom of the oil pan 05, which are integrally formed with the oil pan 05 and arranged along the length direction of the box 01; the exhaust fan 06 is arranged at the rear end of the box 01, and when the exhaust fan 06 is working, it can form a negative pressure near the air outlet 04, so that the air in the box 01 can form an airflow from the air inlet 03, through the heat dissipation ribs 07, and then to the air outlet 04. In the present application, the cold air outside the housing 01 enters the housing 01 from the air inlet 03, passes through the heat dissipation ribs 07, and flows out from the air outlet 04 under the action of the exhaust fan 06 (the main function of the exhaust fan 06 is to cool the cylinder head and cylinder body of the engine 02. The present application makes use of the function of the exhaust fan 06 to form a negative pressure near the air outlet). It can effectively take away the temperature of the outer surface of the oil pan 05, thereby reducing the temperature of the oil in the oil pan 05. The heat dissipation system has a simple structure and occupies a small space. There is no need to use a pump to pump out the oil at the oil pan 05 for cooling as in the prior art. It will not increase the power consumption and weight of the engine 02, has a low manufacturing cost, and can effectively enhance the competitiveness of related products in the market.

[0028] Specifically, an air guide hood 08 can also be set on the end face of the coaxial fan 11 of the engine 02, and the air guide hood 08 can be set in front of the heat dissipation rib 07 (that is, the side of the heat dissipation rib 07 close to the air inlet 03), so that as much gas as possible after entering the box body 01 enters the air guide hood 08, and then is pressurized by the coaxial fan 11, thereby increasing the airflow of the engine 02, and then increasing the airflow passing through the heat dissipation rib 07, thereby improving the efficiency of the heat dissipation system.

[0029] Specifically, an air inlet 09 may be provided between the heat dissipation ribs 07 and the air guide cover 08 and on the oil pan 05, so that cold air can enter the gaps between the heat dissipation ribs 07 more accurately and quickly, further improving the efficiency of the heat dissipation system.

[0030] Specifically, a wind shield 10 can also be set between the engine 02 and the box body 01, preferably set in the upper 1 / 2 area in the height direction of the box body 01. It can be understood that hot air usually goes upward to low temperatures. This structure can effectively prevent the high-temperature hot air on the exhaust side of the engine 02 from flowing back to the intake side of the engine 02, and separate the intake side and exhaust side of the engine into two relatively independent spaces, thereby improving the efficiency of the heat dissipation system of the oil pan 05.

[0031] Specifically, the exhaust fan 06 can be a number of independently controllable fixed-frequency fans, and a temperature sensor (not shown in the figure) is set in the box 01. The temperature displayed by the temperature sensor is used as a control variable to control the working number of the fixed-frequency fans, so as to adjust the air volume of the air outlet, so as to adjust the working condition of the heat dissipation system, maintain the temperature in the box 01 at a desired working temperature, and reduce the self-consumption of electricity in the box 01. Specifically, the exhaust fan 06 can also be a variable-frequency fan, and the temperature displayed by the temperature sensor is used as a control variable to adjust the power of the variable-frequency fan.

[0032] Specifically, the heat dissipation ribs 07 are arranged at equal intervals, and the distance between each heat dissipation rib 07 can be set according to specific usage conditions. There is no limitation here. The equal interval arrangement is easy to process and shape, and makes the wind speed passing through each heat dissipation rib 07 the same, which can evenly take away the heat of the oil pan 05 and achieve better heat dissipation effect.

In addition, many modifications may be made to adapt specific situations to the teachings of the present invention without departing from the central concept of the present invention described herein.
