Abstract

The utility model discloses a throttling silencer, comprising a refrigerant feeding inlet pipe and a refrigerant feeding outlet pipe. A throttling muffler is communicated between the feeding inlet pipe and the feeding outlet pipe and comprises an inner pipe communicated with the feeding inlet pipe and an outer pipe communicated with the feeding outlet pipe, and the part of the inner tube sleeved in the outer tube is radially provided with a plurality of throttling muffle holes. The utility model has simple structure, reduces noise caused by throttling while throttling, reduces the cost of an air conditioner and meets the requirement of users on the aspect of mute of the air conditioner.

Description

The throttling silencing means

Technical field

The utility model relates to a kind of throttling silencing means.

Background technology

Generally be provided with throttling arrangement on the evaporimeter of existing air-conditioning and the conveying pipe of refrigerant road between the condenser, be used for the cold-producing medium of carrying on the conveying pipe of refrigerant road is carried out expenditure and pressure, simultaneously the cold-producing medium that enters evaporimeter is played the adjusting control action.Throttling arrangement generally is made of capillary, choke valve etc., and it mainly utilizes the mouth of pipe or the pipeline more tiny than conveying pipe of refrigerant to realize throttling action.But cold-producing medium is when the tiny mouth of pipe of throttling arrangement or pipeline flow out, and can send the sound of air-flow eruption, produces noise.So generally a silencing means need be set again at the output of throttling arrangement, reduce noise, such silencing means price general charged is higher, has increased the cost of air-conditioner.

Summary of the invention

The utility model purpose provides a kind of throttling silencing means, and it is simple in structure, can reduce the noise that is brought by throttling in throttling, has reduced the cost of air-conditioner, satisfies the demand of user to the quiet aspect of air-conditioning simultaneously.

The technical solution of the utility model is: a kind of throttling silencing means, comprise that cold-producing medium conveying inlet pipe and cold-producing medium transfer out pipe, described conveying inlet pipe and transfer out and be communicated with the throttling muffler between the pipe, described throttling muffler comprise with the interior pipe of carrying inlet pipe to be communicated with and with transfer out the outer tube that pipe is communicated with, interior pipe box is located at the interior part of outer tube and radially is provided with some throttling bloops.

Further, described interior pipe and outer coaxial tube setting, described interior pipe one end opening is communicated with the conveying inlet pipe, and the other end is positioned at outer tube and end sealing; A described outer tube end corresponding with the blind end of interior pipe with transfer out pipe and be communicated with.Cold-producing medium in interior pipe by axial flow changed course be Radial Flow to outer tube, again by in the outer tube by radially changing axial flow into, reduced the throttling noise.

Further, described conveying inlet pipe and interior pipe are wholely set.Promptly carry the port of export of inlet pipe to seal and stretch in the outer tube, and be arranged with some throttling bloops radially in the wall portion that is positioned at outer tube, carry this outlet section of inlet pipe to form the throttling muffler, cold-producing medium is played throttling action, and can not produce throttling eruption noise with outer tube.

Further, described interior pipe is communicated with carrying inlet pipe by flow controller.An end that is flow controller is communicated with carrying inlet pipe, the other end is communicated with interior pipe, cold-producing medium by carry inlet pipe enter flow controller by throttling after, enter interior pipe by flow controller again, make the cold-producing medium after the throttling enter outer tube by the throttling bloop on the interior pipe again, flow out by transferring out pipe at last.The noise that the flow controller output should produce is eliminated by the throttling muffler.

The utility model advantage is:

1. the utility model has reduced the throttling noise of air-conditioning, satisfies the demand of user to the quiet aspect of air-conditioning.

2. the utility model is simple in structure, and can play the effect of throttling and elimination throttling noise simultaneously, has reduced the cost that air-conditioning disposes throttling arrangement and silencing means specially respectively, helps reducing the air-conditioner cost.

Description of drawings

Fig. 1 is the structural representation of the utility model specific embodiment one;

Fig. 2 is the structural representation of the utility model specific embodiment two.

Wherein: 1 carries inlet pipe; 2 throttling mufflers; Pipe in 3; 31 throttling bloops; 4 outer tubes; 5 transfer out pipe; 6 flow controllers.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one:

As shown in Figure 1, a kind of throttling silencing means, comprise that cold-producing medium conveying inlet pipe 1 and cold-producing medium transfer out pipe 5, described conveying inlet pipe 1 and transfer out pipe and be communicated with throttling muffler 2 between 5, described throttling muffler 2 comprise with the interior pipe 3 of carrying inlet pipe 1 to be communicated with and with transfer out pipe 5 outer tubes that are communicated with 4, interior pipe 3 is sheathed on outer tube 4 interior parts and radially is provided with some throttling bloops 31.

Pipe 3 and outer tube 4 coaxial settings in described, described interior pipe 3 one end openings are communicated with carrying inlet pipe 1, and the other end is positioned at outer tube 4 and end sealing; Described outer tube 4 end corresponding with the blind end of interior pipe 3 with transfer out pipe 5 and be communicated with.

Described conveying inlet pipe 1 is wholely set with interior pipe 3, promptly carry the port of export of inlet pipe 1 to seal and stretch in the outer tube 4, and be arranged with some throttling bloops 31 radially in the wall portion that is positioned at outer tube 4, carry this outlet section of inlet pipe 1 to form the throttling muffler with outer tube 4.

Embodiment two

As shown in Figure 2, other structures of present embodiment are identical with specific embodiment one, are not to be wholely set but carry inlet pipe 1 and interior pipe 3, but interior pipe 3 is communicated with carrying inlet pipe 1 by flow controller 6.This flow controller 6 is a capillary restrictor, and an end capillaceous is communicated with carrying inlet pipe, and the other end is communicated with interior pipe.

The utility model is simple in structure, can reduce the noise that is brought by throttling in throttling, has reduced the cost of air-conditioner, satisfies the demand of user to the quiet aspect of air-conditioning simultaneously.
