Abstract
The invention discloses an automobile air-conditioner expansion valve. The automobile air-conditioner expansion valve comprises a valve body, wherein an evaporator inlet, an evaporator outlet, an expansion valve inlet and an expansion valve outlet are formed in the valve body; the evaporator inlet and the evaporator outlet are formed in one side surface of the valve body; the expansion valve outlet and the expansion valve inlet are formed in the side surface of the valve body adjacent to the surface where the evaporator inlet and the evaporator outlet are located; heat isolating end covers are arranged on the valve body and the side surface adjacent to the surface where the expansion valve outlet and the expansion valve inlet are located or the other side surface adjacent to the surface where the evaporator inlet and the evaporator inlet are located; the heat isolating end covers wrap the end parts of the valve body where the side surfaces connected with the heat isolating end covers are located; an inlet/outlet pipeline of the expansion valve can be arranged directly along a front wall metal plate, so that the expansion valve body pointing to a heat source of an engine can be wrapped by the heat isolating end covers, heat radiation influence to the front cabin is reduced, a refrigerant effect is ensured, and the performances of the automobile air-conditioner is further guaranteed.
Description
Technical field
The present invention relates to air conditioning for automobiles field, particularly a kind of motorcar air conditioner expansion valve.
Background technology
Along with people increase the requirement of air conditioning for automobiles comfort level, in car, heat pump performance more and more receives publicity.The structure of conventional expanded valve, the arrangement form of the outlet/inlet pipeline that has limited refrigerant on automobile, cannot install heat insulation structural on expansion valve, expansion valve body is affected by front deck heat radiation etc., affect the effect of refrigerant, and then when air conditioning for automobiles moves, reduced air conditioning for automobiles performance.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can reduce front deck heat radiation impact, guarantee refrigerant effect, and then guarantee the motorcar air conditioner expansion valve of air conditioning for automobiles performance.
To achieve these goals, the technical solution used in the present invention is:
This motorcar air conditioner expansion valve, comprise valve body, on described valve body, be provided with evaporator, evaporator outlet, expansion valve import and expansion valve outlet, described evaporator and described evaporator outlet are located on a side of described valve body, and described expansion valve outlet and expansion valve import are located on the valve body side adjacent with evaporator outlet place face with described evaporator; On described valve body, export on the side adjacent with expansion valve import place face or on the another side adjacent with evaporator outlet place face with described evaporator and be connected with heat insulation end cap with described expansion valve, described heat insulation end cap wraps the end end, place, side being connected with described heat insulation end cap on described valve body.
Described heat insulation end cap is connected by stud with described valve body side.
In the middle part of described valve body, for cuboid two ends are cylinder, on described heat insulation end cap two ends, establish the arc groove with described cylinder adaptation.
Described evaporator and expansion valve import are L-type structural configuration in described valve body two adjacent side, and described evaporator outlet and expansion valve outlet are L-type structural configuration in described valve body two adjacent side.
The invention has the advantages that: this motorcar air conditioner expansion valve, evaporator and evaporator outlet are located on a side of valve body, and expansion valve outlet and expansion valve import are located on adjacent valve body side; On valve body and on the side that expansion valve exports and expansion valve import place face is adjacent or on the another side adjacent with evaporator outlet place face with evaporator, be connected with heat insulation end cap, heat insulation end cap wraps the end end, place, side being connected with heat insulation end cap on valve body; This kind of expanding valve body structure, on expansion valve, each import and export mix can directly be arranged outlet/inlet pipeline along front wall panel beating, then guarantee can realize towards the expansion valve body of engine thermal source the parcel of heat insulation end cap, reduce front deck heat radiation impact, guarantee refrigerant effect, and then guarantee air conditioning for automobiles performance.
Accompanying drawing explanation
The content of below each width accompanying drawing of description of the present invention being expressed and the mark in figure are briefly described:
Fig. 1 is the structural representation of motorcar air conditioner expansion valve of the present invention.
Mark in above-mentioned figure is:
1, evaporator; 2, evaporator outlet; 3, expansion valve outlet; 4, expansion valve import; 5, stud; 6, heat insulation end cap.
The specific embodiment
Contrast accompanying drawing below, the description by optimum embodiment, is described in further detail the specific embodiment of the present invention.
As shown in Figure 1, this motorcar air conditioner expansion valve, comprise valve body, on valve body, be provided with evaporator 1, evaporator outlet 2, expansion valve import 4 and expansion valve outlet 3, evaporator 1 and evaporator outlet 2 are located on a side of valve body, and expansion valve outlet 3 and expansion valve import 4 are located on the valve body side adjacent with evaporator outlet 2 place faces with evaporator 1; On valve body, on the side adjacent with expansion valve import 4 place faces with expansion valve outlet 3 or on the another side adjacent with evaporator outlet 2 place faces with evaporator 1, be connected with heat insulation end cap 6, heat insulation end cap 6 wraps the end end, place, side being connected with heat insulation end cap 6 on valve body.This kind of expanding valve body structure, on expansion valve, each import and export mix can directly be arranged outlet/inlet pipeline along front wall panel beating, then guarantee can realize towards the expansion valve body of engine thermal source the parcel of heat insulation end cap 6, reduce front deck heat radiation impact, guarantee refrigerant effect, and then guarantee air conditioning for automobiles performance.
As preferred version, heat insulation end cap 6 is connected by stud 5 with valve body side.Not only syndeton stability is better for the connected mode of stud 5, and easy accessibility.
As preferred version, in the middle part of valve body, for cuboid two ends are cylinder, on heat insulation end cap 6 two ends, establish the arc groove with cylinder adaptation.This heat insulation end cap 6 and valve body suitability are good, can strengthen the effect of heat insulation of heat insulation end cap 6.
As preferred version, evaporator 1 and expansion valve import 4 are L-type structural configuration in described valve body two adjacent side, and the vertical line line of evaporator 1 center and the expansion valve import 4 centers crossing seamed edge to both sides, place is L-type; Evaporator outlet 2 and expansion valve outlet 3 is L-type structural configuration in valve body two adjacent side, and to export the vertical line line of 3 centers crossing seamed edge to both sides, place be L-type for evaporator outlet 2 centers and expansion valve.This motorcar air conditioner expansion valve, the expansion valve upper inlet/export pipeline of being more convenient for connects along front wall panel beating to be arranged, to guarantee fully parcel valve body of heat insulation end cap 6, guarantees effect of heat insulation.
Specific implementation of the present invention is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out, all within protection scope of the present invention.
