Technical field
The utility model relates to Vehicle Engineering, particularly relates to the improvement of car seat headrest.
Background technology
When automobile uses winter, air-conditioning heating is adopted to heat interior.The air-conditioning heating that commercially available most of vehicle uses is all the water heating type warm-air system used.Water heating type warm-air system relies on the heat of engine combustion, and after engine operation, oil inflame is done work, and the portion of energy of burning is transformed to mechanical energy by piston crank mechanism, and portion of energy is dispersed in air in the mode of heat energy.When driving engine acting, engine temperature rises rapidly, gas temperature in cylinder can up to 1727 ~ 2527 DEG C, if cool not in time, engine component temperature will be caused too high, especially the part directly contacted with high-temperature gas, can, because of the normal tolerance clearance of thermal expansion effects, cause movement parts to be obstructed even stuck.In addition, high temperature also can cause the mechanical strength of engine component to decline, and makes lubricating oil ineffective.Refrigerant fluid also known as anti-freezer, by anti-freezing dope and the liquid that prevents from metal from producing the additive of corrosion and water forming.It needs to have freeze-proof, corrosion protection, heat conductivity and stay-in-grade performance.Driving engine is lowered the temperature to driving engine by the circulation of the refrigerant fluid in cylinder body water jacket, ensures that driving engine is operated in suitable operating temperature always.
Two kinds of working cycle are included, i.e. " cold car circulation " and " normal circulation " in the cooling circulation of driving engine.After car by cold car, driving engine is heating up gradually, and the temperature of refrigerant fluid also cannot open the coolerstat in system, and refrigerant fluid now just carries out " cold car circulation " through water pump in driving engine, and object makes driving engine reach normal working temperature as soon as possible.Along with the temperature of driving engine, cooling-liquid temperature has been raised to the open temp (this temperature is after 80 DEG C usually) of coolerstat, and cooling circulation starts " normal circulation ".Refrigerant fluid at this time from driving engine out, through the radiator of car front end, after heat radiation, then enters driving engine through water pump.Engine coolant flows through driving engine, after heating engines, is driven by water pump, then the heats flowed through under instrument desk carries out interchange of heat, and blowing engine blows over heats, sends warm braw and comes vehicle cabin inside.
But, under extremely cold cryogenic conditions, heat up after engine ignition slower, cooling-liquid temperature rises slowly, and vehicle keeps always " cold car circulation ", under these circumstances, carry out warm braw by force again, not only can not vehicle cabin internal temperature, Engine Coolant Temperature also can be caused to rise more slow, delay to arrive suitable operating temperature.Engine operating temperature is too low, cause the rising of driving engine consumption, dynamic property declines, wearing and tearing increase, if driving engine cold operation for a long time, also can cause carbon distribution, burn insufficient, these all can cause serious consequence to engine body and three-element catalytic, make driving engine and discharge catalysis system end-of-life ahead of time.Therefore in order to use warm braw as early as possible in cold snap, Some vehicles has installed electrical heating wire additional and has carried out auxiliary air conditioner heating, when Engine Coolant Temperature does not reach suitable operating temperature, carries out heating by electrical heating wire auxiliary heat dissipation core body.
The benefit of auxiliary heating to raise the temperature in compartment timely, but to the specific position of human body and some specific vehicle heating less effective.If keep environment inside car Thermal comfort, occupant's temperature equalization everywhere will be kept to be suitable for, there is not the obvious temperature difference, therefore the air outlet blowout warm braw of the instrument desk in occupant front is depended merely on, just be difficult to the temperature of the rear head and neck ensureing occupant, easily cause the temperature contrast of the front face of occupant and rear neck.And modern automobile also becomes more and more popular phaeton, phaeton is not owing to having top cover, warm braw is very easy to run off, especially occupant's neck place, when convertible is run at high speed, heat very easily runs off, and causes occupant's neck to suffer from cold and does not feel well, therefore necessaryly separately the rear head and neck position of occupant to be heated, to keep the traveling comfort of occupant.
