Description
Technical field
The present invention relates to the air-conditioning technical and the physical streams mechanics of automobile.
Background technology
At present, passenger vehicle and truck cabs such as small passenger car, big microbus, taxicar, city motor bus, trolley coach and rail vehicles for transporting passengers, the waste gas in the car is discharged and entering mainly of fresh air exchanges by same vehicle window.But winter and early spring and late autumn be when being cold, the window of can not driving greatly again, otherwise the people on seat window limit can't stand.Air still can not flow in the little window limit air flows that can only allow of windowing, car.Interior space is just so big, atmosphere draught-free, the oxygen that people need suck is constantly inhaled fewer and fewer, the pernicious gas that the carbon dioxide of breathing out and human body discharge refuse, pellet reach from driving engine can be poly-more many more, breathe the circulation mix waste gas of these disease carrying germs and objectionable impurities repeatedly, very big to the health hazard of human body.So can feel a kind of unpleasant peculiar smell when present common electrical automobile of people or taxicar, particularly winter, the people was many and when not driving window, and seat point for a long time makes people's dizziness, feels sick, and allows the people be difficult to stand.The slow interior air of bus standard-sized sheet vehicle window car of the many speed of a motor vehicle of seat people in summer also can not flow, and also can only enter partly new gas and discharge section waste gas, does not satisfy so much human needs.Though the vehicle that other people are few is not serious like this, waste gas can not arranged and taken a breath in the car, and is always disadvantageous to people's health; Especially chaufeur is year in year out in this environment and crawl space work, and bigger to Health cost, this environment easily makes chaufeur drowsy simultaneously, influences traffic safety.
Ventilation is again inseparable with the transmission of heat, and the fast more cooling of air flows better of ventilating is just many more.When it is cold because the inside and outside temperature difference of car is big, the vehicle that the seat people is few as long as each window open some windows and will form the quick convection current of air.Do not need this moment cooling too many in the car again, and need to be incubated and to heat up; Temperature difference when it is hot inside and outside the car is very little, and the standard-sized sheet vehicle window also can not form circulating air, and cooling is seldom still felt muggy and oppressive in the car.Though present passenger vehicle and truck cab skylight loam cake upwards start forward and can advance windscreen in the car, but owing to there is not left and right side cap, the wind major part of loam cake retaining has all flowed away from loam cake bottom the right and left, into the car seldom, because the little interior air of car that can not make of pressure flows away from vehicle window, the cooling effect of playing when particularly it is warm is very little, can only be to stand in over against the skylight opening underperson could feel to obtain a bit in the time of by bus.Now, a lot of summers in passenger vehicle winter are all regulated vehicle interior temperature with air-conditioning, make the interior wind circulation of car will close vehicle window by drum phoenix machine, air-conditioning has air purification unit can remove some objectionable impuritiess, but can not increase oxygen and negative ion, the ventilation of not windowing winter in summer allows the people feel bad equally, and the sensation of " carsickness " is arranged; Air-conditioning also has fan inlet, the self-contained air-conditioner car also has the skylight, the rear portion also has deflation hole in some car, but the air inlet of air-conditioning can only be opened the short time, the fresh air that enters and the waste gas of discharge are seldom, can not satisfy the health needs, moreover only have 1/3rd to use air-conditioning between for a long time in 1 year, all the other times are also used vehicle window and skylight ventilation.Another problem is, there is appreciiable passenger vehicle not adorn air-conditioning at present, truck cab does not have air-conditioning basically, this just makes that the people is cold in winter and hot in summer on the car, meet cold current or " sauna day " seat coach duration point, particularly lorry just as feeling bad at " ice kiln " or " food steamer " lining, though air-conditioning can solve problem cold in winter and hot in summer, the source of consuming energy more.
Summary of the invention
The invention provides ventilation of a kind of passenger vehicle and cab ventilating and air conditioner energy saving device, its main purpose is to solve the ventilation problem that waste gas is discharged and fresh air enters that produces in passenger vehicle and the operator's compartment, makes in the car with fresh air; Because of ventilation must be accompanied by heating and cooling, another purpose is to regulate vehicle interior temperature, can open less or not turn on the aircondition or air-conditioning oil firing (gas) is not energy-conservation.
Above-mentioned purpose of the present invention is achieved in that we know, air flows (wind) is because the inhomogeneous generation of barometric distribution, except that thermal gradient energy makes air flows, make indoor air flows, also have two ways, the one, " blowing (drum) wind ", the 2nd, " taking out (suction) wind "." blowing " " exhausting " all is to use blower fan at present, but wants consumes energy with blower fan.The present invention is power consumption source in addition not, and " exhausting " utilizes " suction effect " (also claiming difference suction effect) physically, produces the suction effect to surrounding liquid or gas exactly with the increase flow rate of fluid.According to Bernou1li equation, its flow velocity increases when fluid passes through narrow place, and narrow place pressure reduces, and just less than the barometric pressure in the external world, the liquid of container or gas will be drunk up and go with the fluid ejection pressure at narrow place under the pressure differential effect in the fluid.Promptly be equivalent to " suction " or " taking out " of blower fan.Another way is got up air trapping with large-diameter pipe exactly, make it flow to the road junction dwindle bore gradually then, air will produce the pressure accelerated flow and go into indoorly, promptly is equivalent to blower fan " blowing " or " drum ", add corresponding air extractor duct, just can make indoor air flows.If the two cooperates " blowing " and " taking out ", form back " taking out " preceding " blowing ", air will amount of flow is bigger flows sooner in the car.
According to this principle collection wind airflow duct more than is installed forward on passenger vehicle and truck cab top.Its stage casing or have only before and after two sections back segment make the Venturi tube that an above channel cross-sectional area changes vertically, near the logical waste gas suction pipe upper end outlet the narrowest place in each Venturi tube takes advantage of the people chamber to communicate in waste gas suction pipe lower end suction inlet and the car.Other position has fan inlet to feed in the car in the middle of the roof of collection wind airflow duct leading portion bottom surface or on left and right sides roof or the car.Collection wind airflow duct is beveled to collection wind airflow duct bottom ports limit downwards forward from the leading portion top, three arm of angle big shield shapes of downcutting are cut from end face, be divided into a cover plate and two identical triangular plates, again two triangular plates are made two pairs of set squares of branch both sides one-tenth such as center line respectively from drift angle, couple together with hinge by the collection wind airflow duct original state before cutting respectively again, but become the collection wind airflow duct admission port of the switch of forming by collection wind airflow duct loam cake and the collapsible side barge board in the left and right sides.On collection wind airflow duct also can be contained in and push up in the car, admission port was on front windshield; Also can be contained in the both sides of car.

The specific embodiment
The present invention is further described below in conjunction with drawings and embodiments.The present invention is suitable for various large, medium and small passenger vehicles (train, rail vehicle and battery-driven car) and truck cab.Its principle all is the same with structure.
According to technique scheme, do collection wind airflow duct 9 with lightweight sheet steel or aluminium alloy plate or composite panel, airflow duct admission port 2 is made rectangular mouthful of (last two jiaos can be circular arc) or flat ellipse mouth, but the square or flat-horn shaped of its leading portion prolate.On passenger vehicle and truck cab top 17, (also can be contained on the box-body truck top, also can stretch to the truck cab top to Venturi tube upward outwards turns on the both sides, back, car and cab-behind-engine lorry can also combine with engine case) collection wind airflow duct 9 forward is installed more than one, also can be collection wind airflow duct leading portion and roof 17 as one, promptly roof 17 as its bottom surface.Its stage casing or have only before and after two sections back segment make the circular or oval Venturi tube 14 that an above channel cross-sectional area changes (flat-horn shaped) vertically, waste gas suction pipe upper end outlet 13 is arranged near the narrowest place in each Venturi tube 14, take advantage of the people chamber to communicate in waste gas suction pipe lower end suction inlet 12 and the car.On collection wind airflow duct leading portion bottom surface 18 or left and right sides car, there are roof ventilation admission port and air door 8 to feed that (collection wind airflow duct leading portion bottom surface roof ventilation admission port 8 can forward slot in the cars in the middle of roof 17, but also transverse opening), before tubaeform admission port 10, also have cut-off wind door 16, be used for the flow direction and the flow size of control sets wind air conducting inner air tube.Fan inlet 1 also can laterally be opened at operator's compartment front windshield upper and lower before the car, also can utilize vehicle window and other fan inlet on the car.Above the back window glass both sides of car or big microbus back window glass, air extractor duct and control gate 11 are arranged, big more than one air extractor duct of microbus and control gate 11 also can be opened in the left and right sides, car bottom, or back window glass is made the air outlet window that open and close up and down can be ventilated.Air door on each fan inlet 8 can be controlled separately and enter charge air, and air door can be in car, also can be outside car, and the admission port air door also has directional tagging.
Along with the variation of weather throughout the year, need control the flow of air into the car, except with opening, outside the size of putting exhaust door into is controlled, can also enter the height of how much regulating vehicle interior temperature of collection wind airflow duct air with switch, promptly collection wind airflow duct 9 is beveled to collection wind airflow duct bottom surface 18 limit mouths downwards forward from leading portion top 7, collection wind airflow duct admission port 2 just becomes an angle that makes progress, downcutting part is one three arm of angle flute profile, three arm of angle flute profiles of downcutting are divided into a cover plate and two identical triangular plates from the end face incision, again two triangular plates are made two pairs of set squares of branch both sides one-tenth such as center line respectively from drift angle, and then couple together with hinge 5 by collection wind airflow duct 9 original states before cutting respectively, but just become by the collection wind airflow duct admission port 2 that collects the switch that wind airflow duct loam cake 3 and the collapsible side air baffle 4 in the left and right sides form.
Vehicle dormer window loam cake 6 is upwards stretched out in the past (also can the skylight do long do wide, admission port is the same with loam cake wide, but it is shorter than loam cake), left and right sides face just forms two phase equilateral triangles, each two diabolo that equate about bundle of lines limit mouth is divided into from the base angle is done, make air baffle by these two diabolo size shape that equate, again skylight loam cake 6 back and two diabolo air baffles are connected as one with hinge 5 by original state then, just become skylight loam cake 6 back and be fixed on the roof and can open around it, the lid that keeps out the wind of closing and open arbitrarily an angle respectively has an identical collapsible side air baffle 5 with the right and left.In car, adorn collection wind airflow duct 9 (or flat-horn shaped has the mozzle 9 of an above Venturi tube) again on the top, alignd with skylight loam cake 6 back in collection wind airflow duct admission port base, or directly in the roof 17 to serve as collection wind airflow duct top, collection wind airflow duct 9 left and right sides sides are directly installed in the roof 17, loam cake 6 back in skylight are hinged on the roof 17.At the tubaeform admission port 10 following dress cut-off wind doors 16 of collection wind airflow duct, cut-off wind door 16 upwards rotates can close the air of coming in from the skylight and flow to collection wind airflow duct then flow in the car, rotate and to close in the air admission car that flows to from the skylight, then flow to collection wind airflow duct Venturi tube 14, also may command cut-off wind door 16 apertures allow the air that flows to from the skylight flow in the car respectively and collection wind airflow duct Venturi tube 14.
Utilize the relative motion that forms with atmosphere after the vehicle take-offs, just there is windstream to advance to collect the wind that wind airflow duct admission port 2 forms certain pressure, its wind speed strengthens with the increase of the speed of a motor vehicle, the 20-30 kilometer just is equivalent to 3 if the speed of a motor vehicle per hour reaches, fresh breeze speed, when the speed of a motor vehicle reached more than 60 kilometers, quite wind speed just can reach more than 6 grades.Because collection wind airflow duct ventilation inlet is big, is again tubaeform, can overcharge the collection air, the moving air of collection just can form certain pressure in pipe further accelerate wind speed.Allow these have wind that pressure has speed to be blown in the car, the car internal gas pressure is increased, air air extractor duct in the car is flowed outside the low car of air pressure, make air flows in the car from the ventilation inlet of car.If allow the moving air of collecting flow to " Venturi tube " by diverging duct, its flow velocity will be higher, open waste gas suction pipe suction inlet and control gate 11, waste gas will be drawn out of outside the car in the car, because the air of rear portion and bottom is taken away the formation negative pressure in the car, the air that front portion and top air pressure are high in the car will be in the low car of air pressure rear portion and bottom flow, it is lower than the outer air pressure of car to form interior front portion of car and top air pressure, the outer fresh air of car will be sucked in the car, add the speed to overtake of getting on the bus and give the air certain pressure that flows in the car, promote leaked-in air mobile suction power that adds in get on the bus back and the car in car and will quicken air flows in the car, reach the purpose of fine ventilation in the car.When being warm admission port and air extractor duct in collection wind airflow duct admission port and Venturi tube and waste gas suction inlet and the car are all opened entirely, form powerful back " taking out " preceding " blowing " impetus, the interior air of car is flowed fast, form " empty hall wind " (can lower the temperature 5～7 ℃), can not only ventilation, can also reach the analgesic purpose of cooling.
Minibus (proud car) and truck cab are (present except that the driving engine hot-water heating formula warming device heating that can adopt the existing non-independent a/c system of automobile winter, the water heating type warming device structural principle of using on the car is: enter heater heats surrounding air from engine cylinder-body or cylinder cap water jacket splitter section refrigerant fluid, air after will being heated by blowing engine is blown in the car warms oneself, refrigerant fluid after turning cold is drawn back driving engine by water pump, so circulation heating, the hot water amount who enters temperature booster is controlled by Heater Valve).Also available tubaeform admission port is received the engine radiator fan behind in the car, the power of blowing by fan blows into tubaeform admission port to the fresh air through radiators heat, close all other admission ports on the car, the air door of opening waste gas suction pipe air suctiton inlet 12 waste gas in car outside the rear portion sucking-off car, negative-pressure sucking will suck the fresh air of heating from tubaeform admission port in the car, add the power of blowing of fan, the fresh air of heating can flow to faster and more, makes the interior air of car warm pure and fresh.Hot air into the car can also slowly flow in the car everywhere or flow in the car everywhere by the porous vent pipe around dividing plate.
Big microbus and bus are because interior space is bigger, bus is Chang Kaichemen also, the calorific requirement of warming oneself winter is more, except that water heating type warming device that can adopt the non-independent air-conditioning of car and the heating of engine radiator warm braw, also can take or take simultaneously to utilize the heating of exhaust pipe of engine high-temp waste gas.
The waste gas of automotive engine generally all under the car afterbody discharge, freeing pipe is very long, the exhaust gas temperature of discharging from driving engine is up to 500～650 ℃, make the exhaust socket with the high thin-walled material of permeability to heat (as aluminum alloy or alloy-steel plate etc.), at the material of freeing pipe external application good heat insulating (as compound insulating material, the laminated vacuum warm material, smear the anti-hot warm material of one deck as glass liner of thermos at internal layer, phase-transition heat-preserving materials etc.) making sleeve is contained in exhaust shroud middle, the freeing pipe afterbody passes from sleeve, the sleeve front portion also can cover on the cylinder body, between freeing pipe and the sleeve interlayer can ventilating air (this structure also has good noise elimination effect, also but air pipe is in the middle of freeing pipe), the anterior pipe end of interlayer be open to the traffic front portion or compartment, top, the interlayer rear portion mouth of pipe is open to the traffic in rear portion or the compartment, bottom, by blowing engine (being used as power with collection wind airflow duct Venturi tube favourable turn or solar power or storage battery motor) air extraction that is deflated the pipe heating in the interlayer is blown into front portion or napex (the dispersion air-out and the controllable direction device of motorcoach self-contained air-conditioner can be adopted in the top) in the car, the air that back blowing engine in the car (being used as power with collection wind airflow duct Venturi tube favourable turn or solar cell or storage battery) is lowered the temperature heating back in the car is from the car rear portion or bottom suction freeing pipe interlayer rear portion.By blowing engine before the car freeing pipe interlayer rear portion Cryogenic air is taken out again and after anterior high temperature progressively heats, blow into front portion or top in the car.Waste gas suction pipe sucking-off waste gas behind the car is still used in ventilation in the car, fresh air through engine radiator heating back by fan in covered pipe is blown into car, so circulate.Replace the combustion chamber of present bus's independence air-conditioning and freeing pipe to heat the air of warming oneself in the car with him, not only saving fuel and manufacturing cost are also much lower.The interlayer freeing pipe that warm material is made also can pass from the heat-preservation cylinder of being close to the bottom, compartment.Utilize exhaust pipe of engine waste heat also to can be used for the vehicle heating that car and truck cab or other have combustion engine, it is lower than water heating type warming device cost.
For keeping vehicle interior temperature, passenger vehicle and truck cab, particularly motorcoach and bus (more piece hinge joint car and double-decker) can add light heat insulation material (as insulation fibre, foamed plastic, phase-transition heat-preserving material etc.) in the car shell, or make hollow sandwich with the lightweight composition fiber, in be coated with the insulation of anti-hot material, also but vehicle window is also with laminated vacuum glass or pairglass or subsides insulation film, vehicle window is not done very greatly, strengthens the sealing of car etc., makes the interior insulation of car every cold.The body temperature of human body itself is exactly one 37 ℃ natural thermal source, strengthens insulation in the car, makes full use of this thermal source warming winter, and especially the many thermals source of bus passenger are big, are equivalent to heat in the car with other thermals source.After adopting the present invention and taking above measure, passenger vehicle and truck cab can not adorned air-conditioning fully, also can feel nice and cool warm summer in interior winter by car.The energy savings emission abatement.
Also can collection wind airflow duct " Venturi tube " rear portion install turbo-machine (also can make in the Venturi tube helix line as rifle in pipe Lay Buddhist line, can quicken rotation and flow velocity) utilize the quick air pressure of Venturi tube outflow to promote wheel blade rotation generation power, or at Venturi tube afterbody external application bearing suit nozzle around an angle of axis tilt more than two, allow the air-flow that quickens to flow out from Venturi tube from the nozzle of tilt axis, spray, utilize recoil to promote it and rotate generation power.Sprocket wheel, belt pulley etc. are installed on rotor again, just can the transmission electrical generator, (also can fan blade be directly installed on the rotor, air pipe laterally picks out from rotor fan (blowing engine).In the middle of also can covering on Venturi tube) from the rear portion adapter of collection wind airflow duct leading portion.Being parked in car down with the wind during parking, direction (or is fixed on collection wind airflow duct front portion in the rotating supporting during fabrication, during parking lockable mechanism is opened, collection wind airflow duct will the box haul automatic steering facings the wind), collection wind airflow duct just can drive the rotating mechanism generating to allow wind blow into, charge a battery reserve power.
At present, the solar cell generation technology is comparative maturity, and field of application is more and more wider.Vehicle all is to travel outdoor, directly be subjected to solar radiation, passenger vehicle is large and medium bus particularly, bus, box-body truck and track train etc., the large tracts of land roof is all arranged, though little proud car and truck cab do not have very big roof, but enough adorn one with individual photovoltaic module, even at cloudy weather, also can be the 12V battery charge, small passenger car also has bigger engine case of area and tail railway carriage or compartment lid, cab-behind-engine lorry also has bigger engine case, solar cell (photovoltaic cell) module or solar battery array are installed thereon, are equipped with controller and enlarge accumulator capacity, form the solar cell power generating system.
