Abstract
The invention discloses a shell structure for an evaporator of a vehicle air conditioner, which comprises a shell body, an evaporator inlet arranged on the shell body and an expansion valve arranged in the evaporator inlet, wherein the shell body is movably connected with a cover body capable of being opened/closed at the evaporator inlet. By adopting the structure, the shell structure disclosed by the invention has the following advantages: (1) the effect on sealing the evaporator inlet provided with the expansion valve is good; (2) the evaporator and the expansion valve can be well fixed, and disassembly is more convenient; (3) because an opened/closed door hinge structure is adopted, assembly and quality inspection are more facilitated, process assembly is more flexible, and a rubber part plug and an evaporator fixing cover can be assembled independently; and (4) the evaporator fixing cover can serve as a subsequently-developed platform-based structure and has relatively high transplantation degree and strong modularization degree, and meanwhile, the development cycle and cost are saved.
Description
Technical field
The present invention relates to automobile air conditioning technology field, particularly a kind of automobile air-conditioning evaporator housing structure.
Background technology
In automobile air-conditioning evaporator, heating power expansion valve is arranged on evaporator inlet, often be called expansion valve, Main Function has two: 1, throttling: the liquid refrigerant of High Temperature High Pressure is after the cutoff port throttling of expansion valve, become the vaporific hydraulic pressure refrigerant of low-temp low-pressure, for the evaporation of refrigerant creates conditions; 2, control the flow of refrigerant: liquid refrigerant is once after entering evaporator, and refrigerant will be evaporated to gaseous state, absorb heat, reduce the temperature in car.Expansion valve controls the flow of refrigerant, ensures that the outlet of evaporator is entirely gaseous refrigerant, if flow is excessive, outlet, containing liquid refrigerant, may enter compressor and produce liquid hammer; If refrigerant flow is too small, evaporate in advance, cause refrigeration not enough; The kind of heating power expansion valve is different according to balance mode, point internal balance type and outer bogie type; Outer bogie type heating power expansion valve divides F type and H type two kinds of structural shapes.At present, expansion valve and evaporator pipeline place do not have sealing mechanism, and expansion valve and evaporator pipeline place need good fixing seal mechanism to ensure that between expansion valve and evaporator, normal work operation is the existing key issue that need solve.
Summary of the invention
Technical matters to be solved by this invention is, for the deficiencies in the prior art, provides a kind of automobile air-conditioning evaporator housing structure, to reach the object to the evaporator inlet good sealing effect being provided with expansion valve.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of automobile air-conditioning evaporator housing structure, comprise enclosure body, the evaporator inlet be arranged in enclosure body, the expansion valve be arranged in evaporator inlet, described enclosure body is connected with the lid at evaporator inlet opening/closing.
Described cover plate mechanism for auto comprises lid, be detachably connected on sealing blocking piece outside lid.
Described lid one side is by hinge on evaporator inlet edge, and described lid is provided with through hole.
Described sealing blocking piece is the rubber blocking piece that shape and lid shape adapt.
Described sealing blocking piece and lid are removably connected by bulb buckle structure.
Described lid is provided with bulb draw-in groove, and described sealing blocking piece is provided with the bulb shape projection be connected in described bulb draw-in groove.
Described bulb draw-in groove is three, is arranged on described lid in triangular shape.
The present invention adopts said structure, has the following advantages: 1, to the evaporator inlet good sealing effect being provided with expansion valve; 2, evaporator and expansion valve can well be fixed, dismantle convenient; 3, owing to adopting open and close type door hinge structure, better assembling and quality maintenance, technique assembling is also more flexible, independently can assemble Rubber Parts blocking piece and evaporator fixed cap; 4, evaporator fixed cap can as subsequent development hardware and software platform structure, and transplanting degree is higher, and the degree of modularity is strong, saves time-to-market and cost simultaneously.

Fig. 2 is decomposition texture schematic diagram of the present invention;
Fig. 3 is the cross section structure figure in the present invention under lid opening/closing two states;
Fig. 4 is the structural representation in the bulb projection sealed in the present invention on blocking piece snaps on lid bulb draw-in groove;
In Fig. 1 ~ Fig. 4,1, enclosure body; 2, expansion valve; 3, lid; 4, hinge; 5, blocking piece is sealed; 6, bulb shape projection.
Detailed description of the invention
A kind of automobile air-conditioning evaporator housing structure as shown in Figure 1 to 4, comprise enclosure body 1, the evaporator inlet be arranged in enclosure body 1, the expansion valve 2 be arranged in evaporator inlet, enclosure body 1 is connected with the lid 3 at evaporator inlet opening/closing.
Cover plate mechanism for auto comprises lid 3, be detachably connected on sealing blocking piece 5 outside lid 3.Lid 3 one side is hinged on evaporator inlet edge by hinge 4, and adopt this structure to open flexibly and to close cover plate mechanism for auto, lid is provided with through hole.Closeouts 5 is the rubber blocking piece that shape and lid 3 shape adapt.Sealing blocking piece 5 is removably connected by bulb buckle structure with lid 3.Lid 3 is provided with bulb draw-in groove, and sealing blocking piece 5 is provided with the bulb shape projection 6 be connected in bulb draw-in groove.The bulb draw-in groove interference fit of bulb shape projection 6 and lid, convenient sealing blocking piece 5 is dismantled with lid 3 and is connected.Bulb shape projection 6 is snapped in bulb draw-in groove, completes the clamping of sealing blocking piece 5 and lid 3.
Bulb draw-in groove is three, is arranged on lid 3 in triangular shape, and bulb shape projection 6 and the interface arrangment shape triangular in shape of the bulb draw-in groove of lid, form the stability of gusseted, ensure that the firm of connection structure.Lid 3 has buckle and screw hole structure, and corresponding mounting hole screw lock, this plays fixation to evaporator and expansion valve.
When needing to open cover plate mechanism for auto, upwards rotated by lid 3 around hinge 4, lid 3 drives sealing blocking piece 5 also rotating opening, facilitates the installation of expansion valve 2, detection.Expansion valve is installed or after having detected, driven by lid 3 sealing blocking piece 5 to close, sealing blocking piece 5 plays good sealing function.
Design of hinges structure opening and closing structure can be convenient for assembly and detect, simultaneously can independent packing with expansion valve rubber blocking piece, saves man-hour, promote production capacity.Rubber blocking piece is designed with the fastening limitation of assembling that bulb buckle structure better realizes soft material, and technique assembling is more prone to.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that technical scheme of the present invention is carried out, or directly apply to other occasion, all within protection scope of the present invention without improving.
