BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condensation system constituting a cooling device, and more particularly to a condensation system having a configuration in which a temperature drop of a refrigerant in a high temperature and high pressure state is maximized.

In general, the condenser existing on 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 heat the outside of the cabinet through the condensation tube to drop the temperature into the liquid refrigerant.

As an example of the condenser which performs this role, it is connected between a compressor for compressing the refrigerant gasified by heat exchange of the evaporator at high temperature and high pressure and a capillary tube which prevents the high temperature / high pressure refrigerant gas from directly entering the evaporator. The condensation tube, which has been bent in a constant shape to set a large unit area on the inner side of the cabinet, has a configuration in which a plurality of fixing pieces are fastened onto the cooling plate, or the condensation tube of the above constitution It was composed of a configuration in which they were placed on wires and welded to each other.

However, the conventional condenser having such a configuration is only a two-dimensional arrangement of the planar body, so the unit area of the condensation tube is extremely limited, and heat exchange with the wire or the cooling plate is very limited. As a result, the liquefaction efficiency of the refrigerant gas passing through the condensation pipe was inevitably low, resulting in a somewhat lower cooling efficiency.

In order to solve the problems of the conventional condenser described above, the applicant of the present invention has filed a Korean Patent Application No. 0005902 "condenser" (hereinafter referred to as a prior art) of January 29, 2003.

1A and 1B are diagrams respectively showing one side view and a developed perspective view of the prior art.

The prior art will be described in more detail with reference to these drawings. As a constitution of the condenser 100 according to the prior art, a condensation tube 110 which is a tubular body used for a conventional condenser and an outer diameter of the condensation tube 110 are described. Cooling having a plurality of insertion grooves 122 and recessed portion of the insertion groove 122 and the plurality of folding pieces 125 formed to be folded in the direction of the insertion groove 122 is cut down the same or slightly larger than the Plate 120 was provided.

Accordingly, after the condensation tube 110 is inserted into the plurality of insertion grooves 122 formed on the cooling plate 120, the condensation tube 110 is folded as the plurality of folding pieces 125 are folded. By holding firmly, the coupling principle was to be mutually fastened.

Then, by pressing the bending parts (A1 to A6) from the portion adjacent to the refrigerant inlet 112 to implement a predetermined three-dimensional shape, the condenser 100 as configured to maximize the unit area of the condenser 100 It was composed of a configuration that improved the cooling efficiency of the).
