Description
Technical field
This utility model relates to a kind of engine-cooling system, belongs to engine cool technical field.
Background technology
Engine-cooling system is the important component part of electromotor, and the Main Function of cooling system is by engine interior generating unit
Heat is divided to take away, it is ensured that the suitable operating temperature of engine part.Generally engine-cooling system is by water pump, charge air cooler, heat radiation
Device (subsidiary fan), thermostat, expansion tank, the water jacket composition of engine body cylinder cap, along with the increase of engine displacement,
The dimensions of the part such as water pump, radiator is the most increasing, and manufacturing cost the most exponentially form is incremented by.
Available engine cooling system is that a high-temperature water pump carries Cooling Water, cooling machine oil cooler, body cylinder cap, through heat radiation
Water pump is returned after device cooling.The direct cooling intercooler of another low temperature water pump, through radiator (if low temperature water pump water intaking is for outward
Portion fetch water, such as river, sea water, then without radiator cool down) cooling after, return to low temperature water pump.As shown in Figure 1.By
Discharging heat in body cylinder cap most, required coolant rate is maximum, and heat sink size is mainly by the heat dissipation capacity of body cylinder cap certainly
Fixed, and the commonly required cooling water flow of oil cooler is less than body cylinder cap, current this arrangement results in major part high temperature
Water is by-pass out, and sees Fig. 1, causes high-temperature water to be not efficiently used, and makes engine radiating efficiency low.For engine low temperature
Water pump loop (subsidiary fan radiator, i.e. non-used river, sea water are as coolant situation), owing to cool down whole charge air cooler,
Low temperature water pump flow will be very big, and water at low temperature is little with Air Temperature Difference, and radiating efficiency is low, and heat sink size certainly will be caused very big,
Manufacturing cost is high.
Utility model content
The purpose of this utility model is to overcome drawbacks described above, it is provided that a kind of novel engine-cooling system, double by high/low temperature
Pump Two-way Cycle and the cooling of charge air cooler two-stage reduce pump capacity and heat sink size, save manufacturing cost.Concrete technical scheme is:
Engine-cooling system includes high-temperature water pump, low temperature water pump, charge air cooler, radiator, oil cooler and engine body
Cylinder cover water jacket, wherein, charge air cooler uses two-stage cooling;High-temperature water pump is sequentially connected with body cylinder cap and charge air cooler high-temperature part, and
Rear high-temperature water returns high-temperature water pump after radiator is lowered the temperature;Low temperature water pump is sequentially connected with oil cooler and charge air cooler low temperature part,
Then water at low temperature returns low temperature water pump after radiator cools down.
Wherein, the radiator in low temperature water pump loop is the radiator of subsidiary fan.
The beneficial effects of the utility model are:
1) due to pump capacity maximum needed for the cooling of body cylinder cap, charge air cooler high-temperature region is connected in high-temperature water pump loop, can
To make full use of the big flow feature of high-temperature water pump, carry out sufficient heat exchange.
2) by charge air cooler high-temperature region sections in series in high-temperature circuit, cryopump flow can be saved, reduce water pump size and low temperature
Loop radiator size.
3) oil cooler is connected in low-temperature circuit, utilizes the feature that water at low temperature is big with the machine oil temperature difference, it is ensured that machine oil fully changes
Heat, is cooled down, beneficially the cooling of electromotor and lubrication.
Accompanying drawing explanation
Fig. 1 is available engine cooling system structure schematic diagram;
Wherein, (a) is high-temperature water loop;B () is water at low temperature loop.
Fig. 2 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is described further.
As it is shown in figure 1, available engine cooling system is a high-temperature water pump carries Cooling Water, cooling machine oil cooler, body
Cylinder cap, through radiator lower the temperature after return water pump.The direct cooling intercooler of another low temperature water pump, returns to after radiator cools down
Low temperature water pump.High-temperature water pump is responsible for cooling machine oil cooler, body cylinder cap, and the commonly required cooling water flow of oil cooler is little
In body cylinder cap, this arrangement results in major part high-temperature water and is by-pass out, and causes high-temperature water to be not efficiently used, makes
Engine thermal efficiency is low.And for engine low temperature water pump loop, owing to cool down whole charge air cooler, low temperature water pump flow is by non-
Chang great, and water at low temperature is little with Air Temperature Difference, radiating efficiency is low, and heat sink size certainly will be caused very big, and manufacturing cost is high.
The engine-cooling system that this utility model provides, as in figure 2 it is shown, charge air cooler uses two-stage cooling, i.e. high-temperature water is with low
Air inlet is all cooled down by warm water through charge air cooler.
High-temperature water pump is responsible for cooling down body cylinder cap and charge air cooler high-temperature part, and high-temperature water passes sequentially through body cylinder cover water jacket and charge air cooler
High-temperature region, returns water pump after radiator is lowered the temperature.Charge air cooler high-temperature region is connected in high-temperature water pump loop, can make full use of
The big flow feature of high-temperature water pump, carries out sufficient heat exchange;Save cryopump flow simultaneously, reduce water pump size and low temperature
Loop radiator size.
Low temperature water pump is responsible for cooling machine oil cooler and charge air cooler low temperature part.Water at low temperature sequentially passes through oil cooler and charge air cooler
Low-temperature space, and after through radiator cool down after flow back to low temperature water pump.Oil cooler is connected in low-temperature circuit, utilizes water at low temperature
The feature big with the machine oil temperature difference, it is ensured that the abundant heat exchange of machine oil, is cooled down, beneficially the cooling of electromotor and lubrication.
