The high-efficiency heat regenerator device successfully achieves the scheme that an aluminum pipeline is adopted and aluminum are basically adopted to substitute copper in the heat regenerator device, greatly reduces manufacturing cost of the heat regenerator device, meanwhile due to the fact that the capillary tube penetrates into and out of the air return tube, prevents electrochemical reaction produced between the hear regenerator device and the aluminum tube, and meanwhile improves heat exchanging efficiency between medium in the air return tube and medium in the capillary tube to a large extent.
Description
Technical field
The utility model belongs to field of refrigeration, especially refers to a kind of regenerator device for refrigeration system
Background technology
Traditional regenerator device that is used for refrigerator, refrigerator mostly is by copper tube muffler and Red-copper Capillary Tube and forms by soldering; But this structure is that the cold-producing medium of low temperature carries out heat exchange by muffler red copper wall, muffler and soldering layer capillaceous, capillary wall and refrigerant inside capillary gas-liquid two-phase in the muffler, it is more complete to reach the gasification of muffler inner refrigerant, refrigerant inside capillary gas-liquid two-phase temperature is lower, thereby promotes the refrigerating efficiency of refrigeration system.But there is the Multi-layer exchanging heat thermal resistance in this constructional device, and muffler only is that the circle wall contacts with capillary simultaneously, so heat exchange efficiency is lower.
Muffler in the tradition regenerator device adopts copper pipe to make, because the cathode copper demand increases in recent years, and the copper resource scarcity, price is opened on the way; And the density of copper is that 8.9X1000Kg/M3 is relatively heavier; And bauxite resource is relatively abundant, and price only is about 1/3 of about copper, and the density of aluminium is 2.7X1000Kg/M3.Therefore adopt the material cost of aluminium only to be 1/8 of copper.Therefore adopting the aluminium instead of copper will be the inexorable trend of whole refrigeration industry.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of efficient regenerator device, and its cost is low, heat exchange efficiency is higher.For this reason, the utility model is by the following technical solutions: it comprises muffler, capillary, it is characterized in that described muffler comprises the aluminum pipe that mediates and the copper connecting tube that is in the aluminum pipe two ends, aluminum pipe and copper connecting tube welding, capillary penetrates from muffler one end again and passes from the muffler other end.
On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme:
Aluminum pipe is connected copper aluminium resistance welded to connect with copper connecting tube, the termination of described copper connecting tube is stretched in the termination of aluminum pipe by reducing.
Aluminum pipe and copper connecting tube adopt solder to be welded to connect, and the termination of described copper connecting tube is by enlarging, and the enlarging position of copper connecting tube termination is stretched in the termination of aluminum pipe.
It arranges protective layer outside muffler, with aluminum pipe and copper connecting tube weld parcel.
Described protective layer adopts thermal shrinkable sleeve or preservative treatment layer, and described preservative treatment layer comprises the plastic-blasting processing, soaks the protective layer of moulding processing layer, electrophoretic process, dipping lacquer processing formation.
The end of described muffler also connects the second copper connecting tube, the second copper connecting tube insert in the end of muffler and with the copper connecting tube welding at place, muffler end, the copper connecting tube at place, muffler end is by enlarging, the capillary that is in outside the muffler is connected with the second copper connecting tube.
The end of described muffler also connects the second copper connecting tube, the second copper connecting tube inserts in the end of muffler and welds with the copper connecting tube at place, muffler end, the copper connecting tube at place, muffler end is in the outer one section spiral surrounding capillaceous of muffler and is connected to outside the second copper connecting tube by enlarging.
The utility model has successfully been realized the basic scheme that adopts aluminum tubes, aluminium instead of copper in the regenerator device, has greatly reduced the manufacturing cost of regenerator device; And in the utility model, capillary penetrates from muffler and passes, and has both avoided producing electrochemical reaction between itself and the aluminum pipe, has significantly improved again in the muffler heat exchanger effectiveness of medium in the medium and capillary simultaneously.
