Description

Condenser

The present invention relates to a condenser, and, in detail, includes an insertion groove formed to embed a condenser pipe on one side, and a plurality of folding pieces formed by cutting a predetermined portion adjacent to the insertion groove to be folded. The condenser pipe is embedded in the insertion groove, and a plurality of folding pieces are folded to grip the condenser pipe so that the condenser pipe is firmly fastened on the cooling plate, and the predetermined state of the cooling plate is completed. By providing a condenser in which a three-dimensional shape is transformed into a predetermined shape by pressing a part, the unit area of the cooling plate and the condenser pipe constituting the condenser can be made larger, thereby maximizing the cooling efficiency of the refrigerant and significantly reducing the condenser manufacturing time. It also relates to a condenser that can reduce the production cost by enabling mass production.

In general, the condenser present in the cooling cycle is a key component that performs heat exchange by the refrigerant gas compressed at high temperature and high pressure through the compressor to the outside of the cabinet through the condenser pipe to heat the temperature drops to the liquid refrigerant, Appropriate specifications should be used depending on the refrigerant flow rate and type.

The condenser is connected between a compressor for compressing the gasified refrigerant at high temperature and high pressure by heat exchange of the evaporator and a capillary tube which prevents the high temperature and high pressure refrigerant gas from directly entering the evaporator and is fixed on the inner side of the cabinet. The coupling structure is fastened by positioning the piece 83 and performing welding.

In the case of the prior art, as shown in FIG. 1A, since the condenser pipe 82 is cylindrically welded to the flat plate-like cooling plate 81 by a plurality of fixing pieces 83, the work is performed. The efficiency was not good, and the hot refrigerant gas is heat exchanged with the cooling plate 81 through the condenser pipe 82, the cooling plate 81 of the plate-like body and the condenser pipe 82 of the cylindrical tubular body mutually There was a problem that the contact surface is extremely small, the heat dissipation effect of heat dissipation to the outside through the cooling plate 81 is greatly reduced.

On the other hand, another embodiment of the conventional condenser is a wire-con type condenser in which the condenser pipe 82 is welded by a plurality of wires 84, as shown in FIG. Although the effect and the work stability are good, a complicated manufacturing process of individually welding a plurality of wires 84 to the condenser pipe 82 has a problem of rising manufacturing cost.

Therefore, the conventional techniques presented as described above, the condenser pipe 82 and the like is a planar body, is only a two-dimensional planar arrangement configuration, the refrigerant gas compressed at high temperature and high pressure state through the compressor is not sufficiently cooled. Not only that, but in order to increase the cooling effect had to configure a large surface area, there was a problem such as difficult to secure the installation space in the fastening configuration.

The present invention has been devised to solve the above problems, a plurality of folds to be inserted so that the condenser pipe is embedded, and a predetermined portion adjacent to the insertion groove is cut to maintain the embedded state of the condenser pipe firmly. The purpose of the present invention is to provide a condenser capable of realizing a simple manufacturing process and maximizing the ground area of the condenser pipe and the cooling plate, thereby greatly improving the cooling efficiency of the refrigerant. .

Another object of the present invention is to perform a bending (bending) operation to press a predetermined portion of the cooling plate in a predetermined shape in the state that the fastening is completed as described above to perform a shape change in a predetermined shape of three-dimensional to see the unit area of the condenser Larger configuration can further improve the cooling efficiency of the refrigerant, and provides a condenser that can minimize the high space utilization and installation space constraints.
