Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figure 1, a kind of automobile oil pan heating and cooling system, automobile includes engine 61, turbocharger 62, uses
The coolant duct for heat exchange is provided with above the heater cores 121 toward interior heating, three.Heating and cooling system
Including interior circulation mechanism, interior circulation mechanism includes the first pipeline for flowing into turbocharger 62 from engine 61 for coolant liquid
11 and coolant liquid is made to flow back to the second pipeline 12 of engine 61 from turbocharger 62, heater cores 121 are arranged in the second pipeline
On 12, coolant liquid is flowed out from engine 61, is cooled down by entering turbocharger 62 after the first pipeline 11 to it, then
By the second pipeline 12 by the heat dissipation of heater cores 121, coolant liquid is finally flowed back in engine 61, is so recycled.
It is provided with first switch 211 on the second pipeline 12, third pipeline 21, third pipe are connected in first switch 211
Road 21, which can guide the coolant liquid on the second pipeline 12, is fed directly to it in engine 61.Coolant liquid is in the second pipeline 12
During flowing, first switch 211 is first flowed through, then flows into radiating core again.First switch 211 is three-way cock,
It can control coolant liquid and flow back to engine 61 by the second pipeline 12 or third pipeline 21, be arranged on third pipeline 21 useful
In the radiating part 3 with 63 heat exchange of oil sump, when coolant liquid is flowed through from third pipeline 21, by radiating part 3 and oil sump 63
Interior machine oil carries out heat exchange.
As shown in Figure 2 and Figure 3, radiating part 3 includes the more heat-dissipating pipes 31 being set side by side, and heat-dissipating pipe 31 with high fever by passing
The metal for the property led is made, and the both ends of more heat-dissipating pipes 31 converge on third pipeline 21.It offers on oil sump 63 for third
The through-hole 631 that pipeline 21 is penetrated and is pierced by, third pipeline 21 is fixed on oil sump 63 by through-hole 631, and the equal position of heat-dissipating pipe 31
In in oil sump 63.
Meanwhile the 4th pipeline 22 for making coolant liquid flow into radiating part 3, the 4th pipeline 22 are also connected on the first pipeline 11
On be provided with the second switch 221 of control piper conducting, second switch 221 can control whether the 4th pipeline 22 is connected.Simultaneously
In the fuel outlet position of the oil sump 63 also free temperature sensor of society, temperature sensor is screwed rod-like structure,
End for sense temperature is inserted into oil sump 63.When usually, temperature sensor can putting oil sump 63
Hydraulic fluid port sealing, temperature sensor when needing to replace machine oil, can directly be screwed down, can be realized and put
Oil.
As shown in figure 4, the ECU electric signal of temperature sensor and automobile connect, while with the ECU of automobile also with first switch
211 and second switch 221 both electric signal connect.Temperature signal in machine oil is passed to automobile ECU, vapour by temperature sensor
Vehicle ECU issues control instruction to first switch 211 and second switch 221 according to temperature signal, and then controls the flowing of coolant liquid.
In cold conditions, the work of the heating and cooling system is divided into two steps.The first step, when automobile starting, machine oil
Temperature is lower, and first switch 211 controls coolant liquid and flows back to engine 61 from third pipeline 21.The coolant liquid come out from engine 61
After by booster, coolant temperature is increased, and it is right by radiating part 3 later that the higher coolant liquid of temperature flows through oil sump 63
Machine oil is heated, so that machine oil fast speed is warming up to operating temperature, alleviates machine oil and occurs diluting and emulsion.
Second step, after machine oil is increased to suitable temperature, first switch 211 controls coolant liquid and flows from the second pipeline 12
Motivation 61 is postbacked, is no longer flowed back to from third pipeline 21.At this point, second switch 221 is opened, is come out from engine 61 and keep work temperature
Its part of the coolant liquid of degree directly passes through the 4th pipeline 22 and enters in oil sump 63, and such machine oil can be effectively maintained at
In operating temperature, it is avoided heating and cooling occur.Meanwhile the coolant liquid heated by turbocharger 62 can be from radiating core
Heat is distributed on body, also the heat of the part can be made to be utilized.
As shown in Figure 1, heating and cooling system further includes expansion tank 5, expansion tank 5 passes through the second pipeline of pipeline connection
12, expansion tank 5 is interior to be full of coolant liquid, and the coolant liquid in cooling system can be kept to remain by the second pipeline 12 and filled
The state being full of is also convenient for observation and supplement of the people for coolant liquid situation.
As shown in Figure 1, being also connected with outer circulation mechanism on engine 61, outer circulation mechanism includes being located at the second pipeline 12
Water pump temperature-regulating module 4 upper and for perceiving water temperature, third pipeline 21 also connects with water pump temperature-regulating module 4, the second pipeline 12 and
Coolant liquid on third pipeline 21 is entered in engine 61 by water pump temperature-regulating module 4.Outer follow is also connected on engine 61
Endless tube road 41 is provided with radiator 42 on external circulation line 41, and external circulation line 41 can draw the coolant liquid in engine 61
Export comes, and enters back into radiator 42 by water pump temperature-regulating module 4, water pump temperature-regulating module 4 is then flowed back to, finally by second
Pipeline 12 returns in engine 61.
When engine 61 is waited when the temperature is excessively high, the starting of outer circulation mechanism, water pump temperature-regulating module 4 drives cold in engine 61
But liquid stream is distributed into radiator 42, and then by the heat of engine 61 toward the external world, and the lower coolant liquid of temperature is finally flowed back to hair
Motivation 61, enables 61 steady operation of engine.
