Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spiral condenser for a heating /

The present invention relates to a spiral condenser of a cooling and heating system. More particularly, the spiral condenser of a heating and cooling system to improve the performance of the cooling and heating system by increasing the heat exchange efficiency through the arrangement of the refrigerant pipe and the arrangement of the heat radiation fins for a narrow space. It is about.

In general, an air conditioner is to induce a temperature change around a system by using a phase change and a temperature change of a refrigerant, such as an air conditioner, a refrigerator, and a heat pump.

The air conditioner includes a compressor for compressing the refrigerant at a high pressure, a condenser for liquefying the compressed gas refrigerant, an expansion valve for adiabatic expansion of the liquefied refrigerant, and an evaporator for vaporizing the refrigerant to absorb external heat.

These compressors, condensers, expansion valves and evaporators are connected to the piping so that the refrigerant can circulate through the closed loop cycle.

In the evaporator and the condenser, heat exchange is performed between the refrigerant and the ambient air, and a phase change occurs when the refrigerant passes through the evaporator and the condenser.

The heat exchange efficiency of the evaporator and condenser in which the heat exchange is performed has a great influence on the performance of the air conditioner, and around them, a blower is installed to generate a flow of ambient air whose temperature is changed through heat exchange.

Particularly, the condenser is designed to dissipate the temperature of the gaseous refrigerant passing through the inside of the condenser, thereby inducing liquefaction of the refrigerant. In general, the condenser repeats linear steel pipes in a zigzag shape in parallel Bending, and bending in the vertical direction to form zigzag shapes in multiple stages.

In other words, when bending in multiple stages, one end is formed in the proper size and then bent alternately in one direction and the other in parallel with the same size with respect to the one end to form an overall cuboid or cube shape. have.

The condenser of such a shape depends on the heat exchange efficiency depending on whether the condensation heat generated during the refrigeration cycle is quickly discharged. Therefore, in order to increase the efficiency, an appropriate shape of a refrigerant pipe and a means such as a heat sink fin and a cooling fan for forcibly dissipating the heat of condensation. need.

First, a type disclosed in Korean Patent No. 10-0713819 (hereinafter referred to as " Prior Art 1 ") among the forms of refrigerant tubes is a conical compression coil spring structure in which a refrigerant tube is spirally wound along a conical shape, This structure allows the refrigerant to move along the spiral shape of the refrigerant tube and increase the possibility of contact of the refrigerant with the inner wall of the refrigerant tube by the centrifugal force.

However, in the case of the above-described prior art 1, since the installation of the heat radiation fin is not easy, the heat transfer area is limited to the outer surface of the refrigerant pipe, and has a conical three-dimensional volume. .

Meanwhile, among the other forms of the refrigerant pipe, the type disclosed in Korean Patent Registration No. 10-0236337 (hereinafter referred to as 'prior art 2') is a coiled bi-pin tube in which a refrigerant pipe and a heat dissipation fin are integrally wound along a conical jig. Thereafter, this is pressed to form a planar shape.

However, in the case of the prior art 2, since the heat radiation fins are integrally manufactured with the refrigerant pipe, the heat radiation area has a somewhat increased effect compared to the prior art 1, but the arrangement of the heat radiation fins has a spiral arrangement like the refrigerant pipe. This requires a space between the inside and the outside of the coolant pipe and the coolant pipe so that air can flow, and the gap portion has a weak heat exchange application.

Furthermore, in the prior art 2, when forming two or more stages in order to extend the length of the refrigerant pipe, the shape of the first and second stage heat dissipation fins having the same curvature is welded to each other so that the shape is maintained. The relationship that is connected to is repeated repeatedly from the end to the end of the next outer end.

That is, when the bi-pin tube is formed in two stages, the first and second stages of the center side are wound to the same diameter, and the heat dissipation fins adjacent to each other are welded, and the second stage of the bifin tube from the second side to the next outer side is the first stage of the next outer side. It is bent toward, and then the structure forming a two-stage relationship with the same curvature is repeated.

Accordingly, it is difficult to form refrigerant tubes in a plurality of stages. When the refrigerant is liquefied in a refrigerant tube in a certain section, the refrigerant can be prevented from circulating in any one of the bent portions, It can not be placed in the same place.
