Referring to fig. 1 to 6, a header assembly for a heat exchanger and a heat exchanger having the same according to an embodiment of the present invention operate as follows.
The first refrigerant and the second refrigerant flow into the first inner tube 2A and the second inner tube 2B, respectively. Since the first refrigerant and the second refrigerant flow in the same manner, the first refrigerant will be described as an example. The first refrigerant flows into the first inner tube 2A at a low speed, and then enters the first chamber 51 through the first through hole 22A. When new high-speed first refrigerant flows into the first chamber 51, more turbulence is generated to mix the gaseous first refrigerant and the liquid first refrigerant, thereby contributing to increased boiling of the first refrigerant in the heat exchange tubes and increasing heat exchange efficiency. After the first refrigerant is sufficiently mixed, it flows into the heat exchange tube through the first communication hole 53A. The first communication hole 53A is small, as with the first through hole 22A, to allow the first refrigerant to flow into the heat exchange tube at a high speed. The first refrigerant and the second refrigerant are completely isolated from all over, whereby the header assembly for a heat exchanger and the heat exchanger having the same according to embodiments of the present invention can be used for a dual system having two refrigerants.
Referring to fig. 1 to 10, the number of openings 12 or the number of connecting pipes 3 may be the same as or different from the number of through-holes 22 according to an embodiment of the present invention. The sizes or diameters of the through holes 22 may be the same or different, the sizes or diameters of the first communication holes 53A may be the same or different, the sizes or diameters of the second communication holes 53B may be the same or different, and the sizes or diameters of the first communication holes 53A and the second communication holes 53B may be the same or different.
Referring to fig. 1 to 10, the inner bore 31 of the connection pipe 3 may have any suitable cross-section such as a circular, oval, rectangular, semicircular shape, etc., according to an embodiment of the present invention, as long as it can be fitted or connected with the heat exchange pipe.
By adopting the header assembly for the heat exchanger and the heat exchanger with the header assembly, for example, the heat exchange efficiency can be improved. Furthermore, the distribution of refrigerant between the heat exchange tubes is improved, the gaseous refrigerant and the liquid refrigerant are better mixed, and the boiling of the refrigerant is promoted.
In addition, the header assembly for a heat exchanger and the heat exchanger having the same according to the embodiments of the present invention may make a dual system structure for circulating two refrigerants simpler.
With the header assembly for a heat exchanger and the heat exchanger having the same according to the embodiments of the present invention, the first chamber 51 may serve as a turbulence chamber to mix the gas refrigerant and the liquid refrigerant, and the first and second communication holes 53A and 53B may be capillary tubes or have a capillary action to mix the gas refrigerant and the liquid refrigerant again before the refrigerant flows into the heat exchange tube, thereby promoting boiling of the refrigerant.
In addition, the collecting main assembly for the heat exchanger and the heat exchanger with the collecting main assembly provided by the embodiment of the invention can make the assembly of the heat exchanger easier and more stable and prevent internal leakage.
While the above embodiments have been described, some of the features of the above embodiments may be combined to form new embodiments.
