Description
Technical field
The utility model belongs to air-conditioner manufacturing technology field, relates generally to the improvement of air-conditioner muffler, is a kind of air-conditioner muffler specifically.
Background technology
The present muffler that uses, the direct soldering of capillary and copper pipe together, mobile cryogenic gas in the copper pipe, flow in capillary tube high-temp liquid.Copper pipe carries out heat exchange with the capillary copper pipe by contacting of soldering layer, makes capillary obtain bigger degree of supercooling before eruption, and copper pipe has the bigger degree of superheat.
Because capillary and muffler soldering length are grown (general 1-2 meters), so must use a large amount of copper pipes to carry out soldering.Soldering formula muffler has following defective: 1. a large amount of copper pipe, cost of raw material height of using; 2. need special soldering equipment and produce, processing threshold height; 3. the contact area of capillary and copper pipe is little, needs the degree of supercooling and the degree of superheat that long muffler can reach to be needed, has strengthened the limitation in the product design; 4. soldering equipment instability causes to lack weldering, influences heat exchange efficiency.
How to improve capillary and muffler syndeton and preparation method, can reduce cost, be convenient to make, this is the present problem demanding prompt solution in present technique field.
Summary of the invention
The utility model provides a kind of air-conditioner muffler for solving the problem that prior art exists, and is convenient to make, and cost is lower, capillary heat exchange efficiency height.
The purpose of this utility model is achieved through the following technical solutions: a kind of air-conditioner muffler, comprise muffler and copper capillary tube, it is characterized in that: described muffler intermediate host is the aluminium muffler, aluminium muffler two ends respectively connect a bronze medal three-way pipe, described copper capillary tube is passed in the middle of copper three-way pipe and aluminium muffler, stretch out from the reducing of two copper three-way pipe outer ends at the copper capillary tube two ends, the outer end reducing of two copper three-way pipes of muffler is connected with copper capillary tube with soldering, with the outer end reducing sealing of two copper three-way pipes.
To improvement of the technical scheme: the inner reducing of described two copper three-way pipes is adopted copper aluminium resistance welded with the two ends of aluminium muffler respectively.
A kind of improvement to technique scheme: described two copper three-way pipes all are to form three-way pipe structure by welding one bypass pipe on the straight tube of a two ends reducing.
To further improvement in the technical proposal: described two overall structures that the copper three-way pipe all is machine-shaping.
To further improvement in the technical proposal: described two copper three-way pipes all are T tubes.
To further improvement in the technical proposal: described two copper three-way pipes all are profiled tee joint pipes.
The utility model compared with prior art has many advantages and good effect:
1. use aluminum pipe to replace the most of copper pipe in muffler middle part, greatly reduce the cost of raw material;
2. use common welding gun and electric resistance welding equipment just can produce, reduced the processing threshold;
3. all participate in heat exchange around the capillary, contact area is big, can shorten muffler length relatively, increases design freedom;
4. do not exist to lack this defective of weldering, homogeneity of product gets a promotion;
5. there is not the capillary bending phenomenon in the process, guarantees the accuracy of capillary flow.
