Detailed description of the invention
Referring to Fig. 1-Fig. 3, it is provided that a kind of vehicle liquid electricity integral type defroster, specifically may be installed on fuel-engined vehicle, including casing 1, the front side of casing 1 and rear side, be equipped with the air inlet 2 of natural wind, the bottom of casing 1 inner chamber, it is provided with the DC fan 3 communicated with air inlet 2, the top of casing 1, is provided with four air outlets 5, above DC fan 3, be sequentially provided with wind collection slot 6, PTC electrical heating elements 8, the PTC electrical heating elements 8 of liquid radiator 7 and six layers communicates with four air outlets 5.
Described liquid radiator 7 can be pipe type or parallel flow type radiator, is specially gilled tube radiator, its liquid inlet 9 and liquid outlet 10, connects with the outlet of automobile engine water-filled radiator and entrance respectively, forms the closed circuit of water liquid.
On the shell of casing 1, being provided with the voltage input end 11 of DC fan 3 and the voltage input end 12 of PTC electrical heating elements 8, both connects with the storage battery on automobile.
Referring to Fig. 1, Fig. 2, the bottom of DC fan 3, equipped with the pendulum wind support 13 that can hide air inlet 2 or rear side air inlet 2 on front side of casing 1, the right-hand member of pendulum wind support 13 is equipped with swing motor 14.Pendulum wind support 13 drives it to swing by swing motor 14, internal-circulation type air intake or outer circulation type air intake can be realized, specifically, when car outer air is more dirty, pendulum wind support 13 can be made to swing to and to hide the position of air inlet 2 on front side of casing 1, it it is now internal-circulation type air intake, the i.e. air inlet 2 on rear side of casing 1 of natural wind in car, enter in casing 1, and when car outer air is cleaner, pendulum wind support 13 can be made to swing to and to hide the position of air inlet 2 on rear side of casing 1, it it is now outer circulation type air intake, the i.e. air inlet 2 on front side of casing 1 of natural wind outside car, enter in casing 1.
Operation principle:
1, electrical heating pattern: during cold-starting automobile, natural wind enters casing 1 inner chamber from air inlet 2, effect through DC fan 3, pendulum wind support 13, subsequently enter in wind collection slot 6, liquid radiator 7, simultaneously, the circuit turn-on of PTC electrical heating elements 8, PTC electrical heating elements 8 sends out heat thermogenetic, wavy metal fin heat radiation (not showing in wavy metal fin figure) on liquid radiator 7, natural wind is heated rapidly, hot blast is discharged in driver's cabin through four air outlets 5, plays defrosting effect immediately.
2, hot-water heating heating mode: in running car way, from the engine cooling water that water-filled radiator outlet is flowed out, it has been the hot water reaching uniform temperature, now can disconnect the circuit of PTC electrical heating elements 8, reduce electric quantity consumption, save cost, hot water exports from water-filled radiator, in the metal tube interted on liquid inlet 9 influent radiator 7 (metal tube figure does not show), metal tube sends out heat thermogenetic, also dispel the heat through wavy metal fin, natural wind in liquid radiator 7 is heated rapidly, hot blast is discharged in driver's cabin through four air outlets 5, also good defrosting effect can be played.After hot water flows through metal tube heat radiation, flow back to water-filled radiator through liquid outlet 10, water-filled radiator outlet, so move in circles.
3, adopt hot-water heating heating mode and electrical heating pattern: this utility model is in adopting the work of above-mentioned hot-water heating heating mode simultaneously, if weather is cold especially, hot blast produces fast not, hot blast temperature is not high enough, satisfied defrosting effect can not be reached, also the circuit of PTC electrical heating elements 8 can be simultaneously turned on, so, the metal tube heating interted on radiator and PTC electrical heating elements 8 send out heat thermogenetic, all dispel the heat through wavy metal fin, natural wind in liquid radiator 7 is heated rapidly, hot blast is discharged in driver's cabin through four air outlets 5, better defrosting effect can be played.
When this utility model is applied to hybrid electric vehicle, operation principle with above-mentioned be applied to fuel-engined vehicle time operation principle, be on all four.
Above-described embodiment is preferred embodiment of the present utility model, and all structures similar with this utility model and the equivalence made change, and all should belong to protection category of the present utility model.
