Solely page is set to be detected using the temperature detecting unit for being arranged on above-mentioned position in engine-cooling system.
According to of the present invention, temperature signal includes ambient temperature signal and passes through cooling in above-mentioned embodiment
Recycle the engine status signal that signal and cooling circulation inlet signal obtain.Ambient temperature signal is intake air temperature signals and water
At least one of case temperature signal.Cooling total amount according to needed for engine status signal can learn engine, so as to logical
Overregulate and whether flow through one of engine cooling apparatus or both, when the first part flow arrangement 30 and the second part flow arrangement 80
For proportional diverter valve, distributing valve etc., can more precisely control, so that cooling capacity matches with engine heat release demand,
It is effectively prevented from the cooling deficiency of engine or the situation of undercooling occurs.
The water tank temperature control device also includes state input block, and the state input block, which is used to receive, supplies work people
The work pattern signal that member is inputted, the work pattern signal include low temperature mode, normal temperature pattern.Also can be arranged as required to
Wash and sweep with water warm up mode etc..
Specifically, when ambient temperature signal is intake air temperature signals, and sweeper heat circulating system sets stateful input
Unit is used to receiving the work pattern signal inputted for staff, and the work pattern signal can include low temperature mode, often
Warm pattern.Illustrate below by taking the embodiment shown in accompanying drawing 1 as an example.
When waiting in the winter time compared with cold season section, operating personnel can make sweeper heat circulating system be in low temperature mode, can also
Referred to as winter job pattern, now Engine Inlet Temperature may be relatively low, and washing stored by water tank sweeps the temperature with water
It is relatively low.
When sweeper heat circulating system is in low temperature mode, and the cooling total amount needed for engine is equal to water tank cooling and held
Amount, the first part flow arrangement 30 of now control unit control are selectively communicated with to heat exchange stream w2, flow through out liquid path q1's
Fluid all flow to the feed liquor path p1 by heat exchange stream w2, and control engine cooling apparatus is not run.
Now, engine 10 is radiated using water tank 20, engine cooling apparatus can not be run, so as to reduce oil
Consumption.It can also prevent water tank 20 from freezing heating in water tank simultaneously.
And the cooling total amount needed for engine is higher than water tank cooling capacity, in order to avoid engine cool deficiency is excessive, institute
Stating water tank temperature control device controls the first part flow arrangement 30 to selectively communicate with to cooling channel w1 and heat exchange stream w2, stream
A part for fluid through going out liquid path q1 flow to the feed liquor path p1 by cooling channel w1, and other parts pass through heat exchange
Stream w2 flow to the feed liquor path p1, and control engine cooling apparatus has supplemented the portion of cooling deficiency with corresponding conditionses operation
Point, fully meet engine radiating requirement.
And the cooling total amount needed for engine can be by suitably selecting engine less than the situation of water tank cooling capacity
Peak power avoids with water tank capacity.
Now, engine 10 is radiated using water tank 20, simultaneously, moreover it is possible to water tank is cooled down using cooling channel w1 and held
The part that measuring to meet is cooled down, and engine cooling apparatus can be run with corresponding condition, so as to reduce oil consumption.Simultaneously
It can also prevent water tank 20 from freezing heating in water tank.I.e. when the cooling total amount needed for engine is held higher than water tank cooling
The part of amount is more, and the other parts cooled down by heat exchange stream w2 are more, and the rotating speed of following fans 40 can be faster.
When summer etc. is compared with the hot season, operating personnel can make sweeper heat circulating system be in normal temperature pattern, can also
Referred to as general job pattern, now Engine Inlet Temperature may be higher, and washing stored by water tank sweeps the temperature with water
It is higher, water tank 20 can not now be heated, now control unit control the first part flow arrangement 30 selectively communicate with to
Cooling channel w1, the fluid for flowing through out liquid path q1 all flow to the feed liquor path p1 by cooling channel w1, utilize radiating
Device charge air cooler assembly 50 is radiated, and will not be repeated here.
The water tank temperature control device includes but is not limited to entire car controller 60 and the (Motronic control maps of Engine ECU 70
Control unit), specifically, the intake air temperature for detecting the engine 10 exports the first temperature detection of intake air temperature signals
Unit can be the temperature module in engine thermostat.
In addition, engine cooling apparatus can be to apply the various devices in engine cool in the prior art, preferably wrap
Include radiator charge air cooler assembly 50 and the fan 40 for radiator charge air cooler assembly 50 force cooling.The fan is preferred
For electronic silicone oil fan, its rotating speed can adjust according to above-mentioned cooling signal, so that the cooling power of engine cooling apparatus
Operation with engine needs to be adapted, and reduces the air mass flow of power consumption penalty and engine surface.
In addition, the present invention goes back a kind of sweeper of body, it is provided with the sweeper according to any one in above-mentioned technical proposal
Sweeper heat circulating system described in.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited thereto.At this
In the range of the technology design of invention, a variety of simple variants, including each particular technique can be carried out to technical scheme
Feature is combined in any suitable manner, and in order to avoid unnecessary repetition, the present invention is to various combinations of possible ways
No longer separately illustrate.But these simple variants and combination should equally be considered as content disclosed in this invention, belong to the present invention
Protection domain.
