Description
Technical field
The present invention relates to a kind of auto air-con, the auto air-con of the overhead type double duct system that particularly vehicle arrangement is used.
Background technology
Current automobile air-conditioning evaporator is the forward type being placed under instrument desk, by the San Chu air port, left, center, right on instrument desk, cold-hot wind is blown out to the temperature that realizes vehicle cab and regulate, the medium-to-high grade car having is incorporated into the cold-hot wind shunting of air-conditioning by pipeline near the quick adjustment that realizes rear space temperature back seat.The former will cause the temperature regulating effect of operator's compartment rear space poor, and the latter is more far better than the former effect.But the preposition mode of this evaporator, restriction due to its bulk and fitting operation, cause the volume of evaporator limited, heat interchanging area is narrow and small, and heat exchange efficiency is low, heat exchange quantity not sufficient, it is monolateral side direction blowing in addition, just make the temperature adjusting of operator's compartment be difficult to reach ideal effect, particularly, under extreme environment climatic conditions, the effect of rear cabin is just barely satisfactory especially.The laminated evaporator of having applied at present, not only effect improved limited, and also its product all needs high, the expensive matching die of degree of precision, causes the manufacturing cost of product high, is difficult to popularize.Therefore, car air-conditioner maker seeking that heat exchange property is high always, compact conformation, with low cost and can realize the A/C product of direct blowing as much as possible and its temperature of quick adjustment within the scope of cab space.
Summary of the invention
The object of the invention is in order to solve the existing deficiency of above-mentioned current auto air-con product.For meeting the development tendency requirement of lightweight, saving metal material and energy and the environment-friendly high-efficiency of auto air-con product, provide a kind of be directly installed on two air channels operator's compartment top, that have two inlet and outlets heat-exchange system structure, can realize that operator's compartment temperature quick adjustment is controlled, compact conformation, A/C evaporator product with low cost.
The present invention is achieved through the following technical solutions.
The present invention is a kind of overhead type double duct system auto air-con.It consists of the shell of A/C upper shell and body skin, in shell, evaporator, wire casing, left and right drip tray and two of left and right ducting system, consist of.Wire casing is arranged along both sides inside upper shell bottom surface; Evaporator is half stretching, extension wing shape to launch, and tightly two ducting systems is encircled, to realize optimal heat exchange each other; Left and right drip tray is closely buckled in the bottom of evaporator left and right wing; Two ducting systems in left and right are symmetrically arranged under the both sides wing of evaporator, each ducting system forms by blower fan, axial-flow fan, helix air-duct spiral case and turnover air channel, blower fan, axial-flow fan etc. are installed a set of in every one end of evaporator, consistent to realize the equilibrium of evaporator heat transfer process.
Outside, two ends, above-mentioned upper shell bottom surface is furnished with inhales each of top mounting plate, for the suction top of A/C, installs fixing.
On one end end face of above-mentioned body skin, arranging two refrigerant inlet/outlet pipe splicing ears; On the surface of the both sides of air inlet duct level attitude body skin, be respectively equipped with temperature indicator and speed control switch, power light, coolant-temperature switch etc.
Above-mentioned left and right ducting system is all independent, symmetrical separately, carries out interchange of heat independently respectively with evaporator.
The invention has the advantages that: (1) A/C is mounted on operator's compartment top, the bulk that can appropriateness increases A/C, improve heat interchanging area and fitting operation is still convenient and easy, can realize thus more quick adjustment and the more stable control of cab space temperature; (2) air-conditioner wind blows from top to bottom, and the exhaust passage with the rotatable blowing forward and backward of two difference, can make thus air-conditioning wind energy directly blow to each corner of cab space, realize the cab space rapid adjusting and good stable control of temperature everywhere; (3) there are two air inlet ducts that are positioned at both sides, front and back, make thus the air of operator's compartment rear and front end all can enter A/C circulation simultaneously, guaranteed the balanced of operator's compartment front and rear part megadyne temperature degree and well controlled; (4) be provided with two independently ducting system carry out interchange of heat with evaporator respectively, accelerated the circulation flow rate of air in cab space, thereby accelerated the speed of interchange of heat and promoted the efficiency of interchange of heat, can reduce thus the bulk of A/C; (5) partly stretch the evaporator designs of wing shape, and make two ducting systems in left and right be placed in the arrangement that is encircling type under it, realize the optimal heat exchange between evaporator and ducting system, obtained best effectiveness of regenerator, can further reduce the bulk of A/C; (6) by partly stretch wing shape evaporator and two independently ducting system design, effectively avoided the high precision requirement of the high matching die of price and product accessories, realized high-efficiency and low-cost manufacture and the use of A/C.
