Background technology
The operate internal car noise that causes of air conditioning for automobiles is the important indicator weighing vehicle idling N state VH performance, also a focus of Shi Ge main engine plants NVH performance development always.The noise complex genesis that operation of air conditioner causes, compressor is one of its main driving source.The vibration of compressor is delivered to body front wall through air-conditioning duct, directly affects internal car noise harmony quality.Generally speaking, the change of vibration of compressor characteristic and body structure response characteristic is comparatively difficult.
Utility model content
The utility model is exactly for above-mentioned technical problem, a kind of low pressure line structure of air conditioning for automobiles is provided, this structure, by being arranged at the rigid conduit on condenser by the vibration passing of compressor on condenser, reduces the noise that compressor produces, and improves the NVH performance of vehicle.
For realizing this object, the low pressure line structure of the air conditioning for automobiles designed by the utility model, comprises low pressure pipeline, and one end of described low pressure pipeline connects compressor, and the other end connects expansion valve, and low pressure line structure also comprises the rigid conduit be fixed on condenser; Described low pressure pipeline comprises low-pressure hose and low pressure steel pipe, and described low-pressure hose comprises the first low-pressure hose and the second low-pressure hose; One end of described first low-pressure hose connects compressor, and the other end connects one end of rigid conduit; The other end of described rigid conduit connects one end of the second low-pressure hose, and the other end of the second low-pressure hose connects one end of low pressure steel pipe; The other end of described low pressure steel pipe connects expansion valve.
Further, described rigid conduit comprises and is fixed on rigid connecting on the support of condenser, parallel with the support of condenser and takes over, and the bottom of described rigid connecting adapter is connected with the rigidity short tube docked with the first low-pressure hose; Top is connected with the rigidity long tube docked with the second low-pressure hose.
Further, the middle part of described rigidity long tube is provided with bending upwards.
The beneficial effects of the utility model are: when not affecting refrigerant flowing, vibration transfer path increases the vibration that refrigerating module absorbs compressor low pressure line, structure is simply novel, cost is lower, be convenient to install and implement, by optimizing vibration of compressor bang path, reducing vibration passing, significantly improving air-conditioning noise and sound quality in car.
Accompanying drawing explanation
Fig. 1 is the vibration passing route map of the utility model mesolow pipeline;
Fig. 2 is the structural representation that the utility model mesolow pipeline connects rigid piping sections;
Wherein, 1-low pressure pipeline, 2-compressor, 3-expansion valve, 4-condenser, 5-rigid conduit, 5.1-rigidity short tube, 5.2-rigid connecting is taken over, 5.3-rigidity long tube, the 6.1-the first low-pressure hose, the 6.2-the second low-pressure hose, 7-low pressure steel pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description is further done to the utility model:
The low pressure line structure of the air conditioning for automobiles as shown in Fig. 1-2, comprises low pressure pipeline 1, and one end of low pressure pipeline 1 connects compressor 2, and the other end connects expansion valve 3, and it also comprises the rigid conduit 5 be fixed on condenser 4; Low pressure pipeline 1 comprises low-pressure hose and low pressure steel pipe 7, and low-pressure hose comprises the first low-pressure hose 6.1 and the second low-pressure hose 6.2; One end of first low-pressure hose 6.1 connects compressor 2, and the other end connects one end of rigid conduit 5; The other end of rigid conduit 5 connects one end of the second low-pressure hose 6.2, and the other end of the second low-pressure hose 6.2 connects one end of low pressure steel pipe 7; The other end of low pressure steel pipe 7 connects expansion valve 3.By being fixed on rigid conduit 5 on condenser 4 by the vibration passing of compressor 2 on condenser 4, after condenser 4, the vibration of compressor 2 obviously reduces, expansion valve 3 is transferred vibrations to again by low pressure steel pipe 7, the vibration be now delivered in car decreases the overwhelming majority, effectively improves the NVH performance of automobile.
As shown in Figure 2, rigid conduit 5 comprise be fixed on condenser 4 support on, parallel with the support of condenser 4 rigid connecting adapter 5.2, the bottom of described rigid connecting adapter 5.2 is connected with the rigidity short tube 5.1 docked with the first low-pressure hose 6.1; Top is connected with the rigidity long tube 5.3 docked with the second low-pressure hose 6.2.The vibration passing of compressor 2 has arrived on condenser 4 by rigidity short tube 5.1 to greatest extent that be connected with the first low-pressure hose 6.1, and the longer rigidity long tube 5.3 of length absorbs vibration further, decreases the vibration be delivered on low pressure steel pipe 7.
In technique scheme, the middle part of rigidity long tube 5.3 is provided with bending upwards.By arranging bending upwards on rigidity long tube 5.3, increasing the length of rigidity long tube 5.3, when considering Bus inner layout space, adding the length of rigidity long tube 5.3 as far as possible.
Add the absorption of vibrations efficiency of compressor 2 by low pressure pipeline 1 and condenser 4 being connected, thus reduce internal car noise sound pressure level, improve sound quality.In the utility model, the fixed form of rigid conduit 5 on condenser 4 can be multiple, as directly fixed: adopt pipe clamp, support etc. to be directly fixed on condenser 4 by rigid conduit 5; Or newly-increased rigidity flow-guiding structure is arranged on condenser 4; With condenser 4 integral type: standing part is designed to condenser integrative-structure.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
