Abstract
The invention discloses an air conditioner by-pass capillary structure, which comprises the following parts: high-low pressure coolant pipe, by-pass capillary and buffer pipe of low pressure coolant pipe, wherein the pipe end of by-pass capillary is plugged in the low pressure coolant pipe directly, which is bent to coolant flowing direction to form the buffer pipe. The invention prevents the pipe wall impaction from coolant obviously, which reduces the vibration acceleration below 5g.
Description
Technical field
The present invention relates to a kind of air conditioner, particularly relate to the bypass capillary structure of air conditioner that a kind of minimizing is impacted the low pressure refrigerant pipe.
Background technology
Commonly used in the existing air conditioner copper pipe structure at this moment capillary is connecting the high-low pressure two ends to bypass capillary structure, and pressure reduction is very big, and refrigerant impacts low-voltage tube, causes the low-pressure side vibration very big.Complain in market, the generation weld bond shatters, and phenomenon is in the majority, more than the actual measurement acceleration 10g.Regular meeting runs into this situation in the time of in the engineering: along the direction as shown low-voltage tube, original fluid is flowing by direction as shown the bigger impact fluid of speed in the low-voltage tube simultaneously from high-voltage tube.This moment is because the impact of high-velocity fluid, tends to cause between high and low pressure pipe the junction vibration bigger, influences pipeline safety and service life.
Bypass capillary structure in the air conditioner coolant system as shown in Figure 1 has a bypass capillary 3 between high-voltage tube 1 and low-voltage tube 2, the pressure differential that exist owing to two ends this moment, and refrigerant can flow to low-voltage tube 2 through capillary 1 from high-voltage tube 1.Impact refrigerant and caused the vibration of high and low pressure pipe junction bigger, its acceleration of actual measurement surpasses 10G (standard code 5G is following).Air-conditioning uses such bypass capillary structure in the past, too high, low-voltage tube junction just takes place shake and split the situation of reprocessing.
Summary of the invention
For overcoming above-mentioned technical deficiency, the vibration that the object of the present invention is to provide minimizing that the low pressure refrigerant line shock is caused makes refrigerant flow smooth and easy and improves the bypass capillary structure of air conditioner of security.
For achieving the above object, the technical solution used in the present invention provides a kind of bypass capillary structure of air conditioner, include the high-low pressure refrigerant pipe and the connected bypass capillary that are connected with air conditioner, wherein: bypass capillary and low pressure refrigerant pipe junction are provided with the separator tube that always patches into the low pressure refrigerant pipe, and to the bending of refrigerant flow direction.
Described separator tube is that the bypass capillary pipe end is inserted behind the low pressure refrigerant pipe directly to the bending of refrigerant flow direction.
Described separator tube is to insert a tube connector consistent with the refrigerant flow direction of low pressure refrigerant pipe at the bypass capillary pipe end, and inserts in the low-voltage tube.
Effect of the present invention is to insert low-voltage tube after the direct bending of the capillary of this structure, makes Way out consistent with original refrigerant flow direction in the low-voltage tube, and significantly shedding refrigerant, that the impact of tube wall is improved effect is apparent in view, and making vibration acceleration is below the 5g.

Fig. 2 is a fluid impact pipeline vibration-proof structure schematic diagram of the present invention.
Among the figure:
1, high-voltage tube 2, low-voltage tube 3, bypass capillary 4, separator tube
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated bypass capillary structure of air conditioner of the present invention.
As shown in Figure 2, bypass capillary structure of air conditioner of the present invention, include the high and low pressure refrigerant pipe and the connected bypass capillary that are connected with air conditioner, bypass capillary 3 is provided with the separator tube 4 that always patches into the low pressure refrigerant pipe with low pressure refrigerant pipe 2 junctions, and to the bending of refrigerant flow direction.Described separator tube 4 is that the bypass capillary pipe end is inserted behind the low pressure refrigerant pipe directly to the bending of refrigerant flow direction; Described separator tube 4 also can insert a tube connector consistent with the refrigerant flow direction of low pressure refrigerant pipe 2 at bypass capillary 3 pipe ends, and inserts in the low pressure refrigerant pipe 2.
Below specific implementation process is described further:
Shaken at the bypass capillary junction of being mentioned in the patent background and to be split phenomenon, pipeline structure has been carried out dissection and analysis completely, consequently since the high speed refrigerant intense impact of low-voltage tube caused.Change this situation, need reduce the impulsive force of fluid to tube wall, two kinds of ways are arranged: one reduces fluid flow and flow velocity or changes the impulsive force direction of fluid to tube wall.Fluid flow and flow velocity are certain; Its two, to changing fluid the impulsive force direction of tube wall is carried out structural change.
As shown in Figure 2, this is a fluid impact pipeline vibration-proof structure schematic diagram, and the direction of arrow flows out direction for the refrigerant fluid among the figure.This structure has adopted the direct fluid design, makes the equidirectional outflow of original fluid in high speed impact fluid and the low-voltage tube, has reached the purpose of decompression vibration damping like this.Its structure is to include high-low pressure refrigerant pipe and the connected bypass capillary that is connected with air conditioner, at bypass capillary and low pressure refrigerant pipe 2 junctions the separator tube 4 that always patches into the low pressure refrigerant pipe is set, and to the bending of refrigerant flow direction.Described separator tube 4 is that the bypass capillary pipe end is inserted behind the low pressure refrigerant pipe directly to the bending of refrigerant flow direction.Separator tube 4 also can be to insert a tube connector consistent with the refrigerant flow direction of low pressure refrigerant pipe at the bypass capillary pipe end, and inserts in the low pressure refrigerant pipe.Because capillary two ends pressure reduction is big, the refrigerant of ejection becomes 90 degree to impact low-voltage tube, causes vibration acceleration excessive.Analyze vibration principle, to insert low-voltage tube after the direct bending of the capillary of this structure, make Way out consistent with original refrigerant flow direction in the low-voltage tube, reached the purpose of buffering decompression vibration damping like this, the vibration acceleration that uses actual measurement pipe 2,3 junctions after this structure is less than 5G, and it is apparent in view to improve effect.Also can be to insert a tube connector consistent, as separator tube and insert in the low-voltage tube with the refrigerant flow direction of low pressure refrigerant pipe at the bypass capillary pipe end.Play the effect of buffering decompression vibration damping equally.
The fluid impact pipeline vibration-proof structure of this patent can be applicable to anyly have in the circuit design that fluid impact causes bigger vibration, and managing 3 diameter simultaneously should be much smaller than the diameter of pipe 2.
