Abstract

The utility model provides a diffusion-absorbing-type refrigerator core, and relates to the technical field of a refrigerator core structure. The refrigerator core comprises a lifting pipe, an evaporator, an absorber, a liquid receiver, a condenser, a balance pipe, a liquid supply pipe and a dilute solution pipe. The pipes are connected in a punching and flanging mode, wherein one pipe is punched and flanged outwards, and another pipe is welded to the flanged portion of the pipe. A hole formed in the punching and flanged mode is burr-free, and the inner walls of the pipes are smooth; welding is achieved outside the pipes, steps higher than the pipes cannot form in the pipes, liquid cannot be accumulated in the pipes, and accordingly stability of the diffusion-absorbing-type refrigerator core is improved, and use effects and service life of the refrigerator core are guaranteed. Welding sticks are needless to be added in welding, difficulties of manual welding and mechanical welding are reduced, the welding degree is easy to control, and the connection strength between the pipes is strengthened.

The utility model content

The purpose of this utility model is to provide a kind of diffusion absorption refrigerating machine movement, the connected mode waste labour, the welding difficulty that overcome the pipeline that has the diffusion absorption refrigerating machine movement now are large, thereby the rough easy formation hydrops of connecting surface reduces the result of use of refrigeration machine movement and the defective in service life, thereby provide a kind of inner wall smooth to be difficult for forming stability, reduction manual welding, the machinery welding difficulty that hydrops improves diffusion absorption type refrigeration machine core, and can strengthen the diffusion absorption refrigerating machine movement of the bonding strength between the tube and tube.

The technical scheme that the utility model adopts is: the diffusion absorption refrigerating machine movement comprises riser, evaporimeter, absorber, liquid reservoir, condenser, balance pipe, feed pipe and weak solution pipe, the connected mode of described pipeline enclosure adopts the piercing and flanging structure, the outside punching of one pipeline and flange, another pipeline and the welding of its flange place specifically comprise following a few place:

Described condenser and balance pipe interface, condenser and feed pipe interface be piercing and flanging outside pipe, and balance pipe and feed pipe weld with the piercing and flanging place of condenser respectively;

Described evaporimeter and balance pipe interface, evaporimeter and feed pipe interface be piercing and flanging outside pipe, and balance pipe and feed pipe weld with the piercing and flanging place of evaporimeter respectively;

Described absorber and weak solution interface tube place be piercing and flanging outside pipe, the piercing and flanging place welding of weak solution pipe and absorber;

Described liquid reservoir and balance pipe interface, liquid reservoir and weak solution interface tube place be piercing and flanging outside pipe, and balance pipe and weak solution pipe weld with the piercing and flanging place of liquid reservoir respectively.

Described piercing and flanging adopts full-automatic punching flanging device to carry out.

The utility model has the advantage of:

(1) pipeline adopts piercing and flanging, and without burr, inner-walls of duct is smooth;

(2) can not produce the step that is higher than pipe at pipe interior, can not produce hydrops, thereby improve the stability of diffusion absorption type refrigeration machine core, ensure result of use and the service life of refrigeration machine movement;

(3) the pipe external welding need not to add welding wire, reduces manual welding, machinery welding difficulty, and the welding degree grasps easily, thereby strengthens the bonding strength between the tube and tube.
