During the driving process of the car, due to metal friction and some other reasons, the temperature of the engine oil inside the engine will gradually increase. Since the viscosity of the engine oil becomes thinner with increasing temperature, its lubrication ability will be reduced, so an oil cooler is needed to accelerate the heat dissipation of the engine oil to keep it at a lower temperature.

The cooling device only uses a fan to cool the oil pump from the outside, and the cooling effect is poor. It cannot effectively cool the discharged high-temperature oil, causing the oil pump to repeatedly inhale high-temperature oil. As a result, the oil pump is always in a high-temperature state. Running at high temperatures will aggravate mechanical wear. It is not practical and greatly reduces the service life of the machine. Summary of the invention

Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4 The embodiment of the utility model proposes a cooling device for an oil pump, including an oil pool 9, one end of the oil pool 9 is connected to an oil inlet pipeline 1, the other end of the oil pool 9 is connected to an oil outlet pipeline 2, an oil pump 3 is installed on the oil inlet pipeline 1, and a box 4 is installed on the oil outlet pipeline 2. The interior of the box 4 is fixedly connected with a partition 43, and the partition 43 divides the box 4 into a first box 41 and a second box 42. The first box 41 and the second box 42 are both provided with a first cooling component 5. The interior of the first box 41 is provided with a first cooling component 5. A temperature control sensor 6 is installed at the input end at the bottom of the wall. The model of the temperature control sensor 6 is MF52. The first cooling component 5 includes a plurality of semiconductor refrigeration strips 51. The semiconductor refrigeration strips 51 are fixedly connected to the partition 43. One end of the semiconductor refrigeration strip 51 extends into the first box body 41, and the other end of the semiconductor refrigeration strip 51 extends into the second box body 42. A fan 52 is also installed inside the second box body 42. The fan 52 is located on the side away from the partition 43. When the temperature control sensor 6 senses that the oil temperature is higher than the threshold value, the temperature control sensor 6 The sensor 6 will control the semiconductor refrigeration strip 51 and the fan 52 to start, and then the cold end of the semiconductor refrigeration strip 51 in the first box 41 will directly absorb heat and cool the high-temperature engine oil, which greatly improves the heat dissipation efficiency, avoids the engine oil from becoming thinner and then destroying the oil film between the machines, aggravates the mechanical wear, and reduces the service life of the machine. At the same time, the fan 52 in the second box 42 will dissipate the heat from the hot end of the semiconductor refrigeration strip 51 to ensure that the semiconductor refrigeration strip 51 can work normally. The second box 42 is provided with a vent on one side of the fan 52, and a filter is provided at the vent. The vent can effectively allow the fan 52 to discharge the heat generated by the hot end of the semiconductor refrigeration strip 51. The setting of the filter effectively protects the fan 52 and the hot end of the semiconductor refrigeration strip 51. The end of the semiconductor refrigeration strip 51 in the first box 41 extends to the inner wall surface of the first box 41 away from the partition 43, which increases the contact area between the cold end of the semiconductor refrigeration strip 51 and the engine oil, so that the high-temperature engine oil is fully in contact with the cold end of the semiconductor refrigeration strip 51, which greatly improves the heat dissipation effect.

[0028] Reference Figure 1-4An air intake grille 7 is connected to the outer wall surface of the first box body 41 by bolts, and a second cooling component 8 is arranged in the cavity between the air intake grille 7 and the first box body 41. The second cooling component 8 includes a condenser 81, and the condenser 81 is installed on the outer wall surface of the first box body 41. A water tank 82 is installed at the bottom of the cavity between the first box body 41 and the air intake grille 7. A circulation pump 83 is installed on the right side of the water tank 82. The input end of the circulation pump 83 is connected to the output end of the water tank 82, and the output end of the circulation pump 83 is connected to the input end of the condenser 81. The input end of the water tank 82 is connected to the output end of the condenser 81. A heat dissipation fin 84 is clamped between the tube bodies of the condenser 81. When the oil temperature sensed by the temperature control sensor 6 is higher than the threshold value, the temperature control sensor 6 will control the circulation pump 83 to start, and then the circulation pump 83 draws coolant from the water tank 82, and The coolant is transported to the condenser 81, so that the coolant can further cool the high-temperature engine oil in the first box 41 through the condenser 81, and the cooling fins 84 can absorb heat and cool the condenser 81, so that the heat absorbed by the coolant is transferred to the cooling fins 84 through the condenser 81. At the same time, when the car is moving, the flowing air will be blown to the second cooling component 8 through the air intake grille 7, and the second cooling component 8 will be cooled by external blowing. At the same time, the air intake grille 7 can also prevent stones from damaging the second cooling component 8, further enhancing the heat dissipation effect while greatly improving the practicality. The semiconductor refrigeration strip 51, the circulation pump 83 and the fan 52 are all electrically connected to the temperature control sensor 6, and the temperature control sensor 6 is electrically connected to the external power supply, so that the temperature control sensor 6 can control the opening and closing of the semiconductor refrigeration strip 51, the circulation pump 83 and the fan 52.

[0029] The specific implementation method is as follows: when the car starts, the oil pump 3 starts to rotate, draws oil from the oil pool 9, and delivers the oil to various components of the engine. When the car is running for a long time, the inside of the engine will overheat and the oil will absorb the heat in the engine to cool the engine. The high-temperature oil that has absorbed the heat will flow back to the oil pool 9, waiting to be re-absorbed by the oil pump 3. After the oil pump 3 re-absorbs the high-temperature oil, the oil pump 3 and the internal machinery are prone to high temperatures. When the oil flowing to the oil pool 9 exceeds the threshold set by the temperature control sensor 6, the temperature control sensor 6 controls the semiconductor refrigeration strip 51, the circulation pump 83 and the fan 52 to start. When the high-temperature oil flows into the first box body 41, the cold end of the semiconductor refrigeration strip 51 will directly cool the high-temperature oil, and the fan 52 will dissipate heat and cool the hot end of the semiconductor refrigeration strip 51, so that the semiconductor refrigeration strip 51 can work normally. The cooling fins 84 also cool the condenser 81 and the cooling fins 84 also cool the condenser 81, thereby further enhancing the heat dissipation effect on the high-temperature oil. During the driving of the vehicle, the flowing wind will pass through the air intake grille 7 and blow toward the second cooling component 8 to cool the second cooling component 8 externally. At the same time, the air intake grille 7 can effectively prevent stones from damaging the second cooling component 8, and can also prevent dust from being adsorbed on the condenser 81, thereby reducing the cooling effect of the condenser 81. After the high-temperature oil is cooled by the first housing 41, it will flow back into the oil pool 9. At this time, the oil pump 3 inhales the cooled oil from the oil pool 9, thereby achieving cooling inside the oil pump 3.
