Description
Technical field
The present invention relates to a kind of pipe arrangement of air-conditioner outdoor unit.
Background technology
Air-conditioner is family's durable consumer goods of commonly using, guarantees that its reliably working is unremitting the pursuing a goal of air-conditioner manufacturing enterprise, also is the basis that its product is participated in market competition.According to the market survey situation, modal fault comes from pipe arrangement in the air-conditioner course of work at present.Crackle appears in pipe arrangement even the pipe that breaks and the inefficacy of matched tube structure is usually expressed as; cause refrigrant leakage; air-conditioner can't work; trace it to its cause; except all kinds of accidents of raw material and manufacture process; because the unreasonable pipe arrangement fatigue failure that causes of design is the most common; and usually can show as the batch property and split pipe or the disconnected event of running affairs; more common way is to become originally to guarantee reliability by " sacrifice "; present air-conditioner outdoor unit pipe arrangement utilizes a plurality of length " U " type pipeline combination around the compressor circumference to realize vibration damping, pipe arrangement vibration and stress when reducing air-conditioner work.Such design concept can cause pipe arrangement longer usually, and raw materials consumption is serious, causes product cost high, has weakened its product market competitiveness, simultaneously, also is unfavorable for the realization of enterprise's " energy-saving and emission-reduction " target.
Summary of the invention
The invention provides a kind of pipe arrangement of air-conditioner outdoor unit, it not only can reduce pipeline vibration, noise and fracture, and reduces the pipe arrangement cost.
The present invention has adopted following technical scheme: a kind of pipe arrangement of air-conditioner outdoor unit, it comprises blast pipe and muffler, blast pipe and muffler are separately positioned on the compressor, described blast pipe comprises leading portion, stage casing and back segment, the leading portion of blast pipe is vertically set on the exhaust outlet of compressor and is connected with exhaust outlet, the back segment of blast pipe is connected with cross valve, the stage casing is between leading portion and back segment, carrying out transition by the stage casing between leading portion and the back segment is communicated with, described muffler comprises bend pipe I and bend pipe II, linkage section in the middle of between bend pipe I and bend pipe II, being provided with, one end of bend pipe I is connected with gas returning port on the fluid reservoir of compressor, one end of bend pipe II is connected with cross valve, two ends at middle linkage section are connected with the other end of bend pipe I and the other end of bend pipe II respectively, also being provided with low pressure valve adapter and condenser on cross valve takes over, the end that low pressure valve is taken over is connected with cross valve, the other end that low pressure valve is taken over is connected with the low pressure valve of air-conditioner outdoor unit, the end that condenser is taken over is connected with cross valve, and the other end that low pressure valve is taken over is connected with the condenser of air-conditioner outdoor unit.
The stage casing of described blast pipe is by the curved position of combination II, straightway II and the bend pipe IV of the curved position of the combination that comprises successively bend pipe III, straight tube I, two complementary angles degree after front I, interlude main body, U-shaped bend pipe, straightway I, two complementary angles degree, and leading portion is connected with back segment with the bend pipe IV by the curved position of combination II, the straightway II of the curved position of the combination of bend pipe III, straight tube I, two complementary angles degree I, interlude main body, U-shaped bend pipe, straightway I, two complementary angles degree successively.
Linkage section comprises bend pipe V, straight tube II, bend pipe VI, middle linkage section main body, U-shaped bend pipe, straight tube III and curved position arc pipe from front to back successively in the middle of described, and the bend pipe I is passed through bend pipe V, straight tube II, bend pipe VI, middle linkage section main body, U-shaped bend pipe, straight tube III and be connected a position arc pipe to be connected with the bend pipe II successively.
The present invention has following beneficial effect: after having adopted above technical scheme, the model frequency of pipe arrangement of the present invention and compressor operating Frequency point, particularly the distribution of the spacing of operating frequency point is more even, has effectively reduced the resonance probability that causes by making the assembling inconsistency.The natural frequencies of pipe arrangement pipeline structure of the present invention is higher, all more than 20Hz (mode that the corresponding compressor body of the first six rank intrinsic frequency swings and rocks), therefore the reliability of pipe arrangement under the inoperative operating mode further improves, and the reliability under the inoperative operating mode refers at the probability less that falls, causes from the low-frequency excitation on road surface in the transportation pipeline resonance.Matched tube structure of the present invention pipe stress when normal operation reduces, and the pipe arrangement upper stress can distributing equilibrium, therefore avoid resolving the generation of running affairs, further improves the reliability of product.Air conditioner piping of the present invention has reduced product pipe arrangement cost so that outdoor complete machine oscillation and noise obviously reduce under the prerequisite that guarantees product quality and reliability.Interlude of the present invention wherein two sections for connecting by the curved position of two complementary angles degree combination, can reduce like this rigidity of pipe arrangement, particularly the rigidity of circumferencial direction is excessive and to the constraint that compressor brings, and can also greatly improve the impact that the refrigerant pressure fluctuation causes pipe arrangement.
