The present invention relates to a condenser for refrigeration and air conditioning configured in a whirlwind form to improve heat dissipation performance and increase heat exchange efficiency.

In general, a refrigerator compresses a gaseous refrigerant into a liquid state at a high temperature and high pressure and provides a circulation force, and a condenser that forms a heat exchange (heat release) with the outside air and condenses the compressed refrigerant to a room temperature and high pressure state. (Condensor), Capillary Tube which changes the condensed refrigerant through the capillary tube to low temperature and low pressure, and performs heat exchange (heat absorption) through the low temperature low pressure refrigerant, and changes the phase to gas state It is provided with a refrigeration cycle to sequentially circulate the evaporator (Revaporator) to be returned to.

Among the components forming the refrigeration cycle, the condenser and the evaporator require high heat exchange efficiency. Of these, the condenser is used in various refrigeration and air conditioning products such as a refrigerator or an air conditioner, An apparatus for condensing and liquefying a refrigerant. The high temperature and high pressure gas refrigerant that has passed through the compressor is converted into a cold liquid low temperature refrigerant.

The first header 10 and the second header 11 may each have a role of introducing a heat exchange medium and a role of flowing out a heat exchange medium, and the first header 10 is a refrigerant flow radiating unit. If the heat exchange medium is introduced into the second heat exchange medium, the second header 11 serves to discharge the heat exchanged heat exchange medium to the outside while flowing the refrigerant flow heat dissipation unit 20. Of course, the roles of the first and second headers 10 and 11 may be changed.

In addition, each of the first and second headers 10 and 11 may have a heat exchange medium in the longitudinal direction of the first and second headers 10 and 11 or discharge the heat exchange medium flowing in the longitudinal direction. 12 should be formed, and according to the embodiment of the user, the shape may have a variety of shapes, such as cylindrical, rectangular.

In addition, a plurality of coupling holes 13 formed in the longitudinal direction to be spaced apart in the longitudinal direction are formed so that the ends of the refrigerant flow radiating unit 20 to be described later communicate with each other.

The refrigerant flow heat dissipation unit 20 is a heat exchange medium is introduced from one of the above-mentioned first and second headers (10, 11) (assuming that the heat exchange medium is introduced from the first header 10 in the embodiment), As it flows in the inner longitudinal direction, it consists of a plurality of main heat sinks 21.

The main radiator 21 has a rectangular cross section, and the refrigerant communication hole 22 through which the heat exchange medium flows in the longitudinal direction is formed therein, and the refrigerant communication holes 22 are the main heat radiation. The interior of the sieve 21 is spaced apart from each other by a predetermined interval in the width direction to form a plurality of perforations.

One end of the plurality of main heat sinks 21 correspond to and communicate with the coupling holes 13 of the first header 10 described above, and the other ends correspond to the coupling holes 13 of the second header 11, respectively. The plurality of main radiators 21 are coupled to communicate with each other, and are continuously installed in the longitudinal direction of the first header 10 or the second header 11, and the heat exchange medium supplied to the first header 10 is The heat exchange medium flowing into one end of the plurality of main heat sinks 21 and flowing inside the plurality of main heat sinks 21 moves to the second header 11, and then the inlet / outlet of the second header 11 is formed.
