Description

[0002] Condenser having integrated receiver drier [0003]

The present invention relates to a condenser used in an air conditioner for a vehicle. More particularly, to a receiver integrated condenser in which a condenser and a receiver are integrated to improve space utilization.

Generally, a condenser is a kind of heat exchanger that performs a function of introducing a gaseous refrigerant of high temperature / high pressure and converting it into a liquid phase by cooling. Among the condensers performing these functions, the multi-stage gas-liquid separating type condenser is provided with a plurality of baffles in one or both of the header tanks so that the refrigerant flows through the plurality of flow passages, while the refrigerant passes through the inside of the condenser in a zig- Heat is discharged through a tube and a fin to condense the gaseous refrigerant into a liquid phase.

On the other hand, the receiver is disposed between the condenser and the expansion valve, and has a function of temporarily storing the refrigerant liquefied in the condenser so that a necessary amount of the refrigerant can be supplied to the evaporator, and a function of separating the gaseous refrigerant contained in the refrigerant derived from the condenser . Recently, a condenser and a receiver have been integrated into a condenser and a condenser integrated with each other in order to utilize space of a limited engine room of a vehicle.

A cross-sectional view and a refrigerant flow chart illustrating an example of the conventional receiver integrated condenser is shown in FIGS. 1 and 2, respectively.

As shown in the drawing, the conventional receiver integrated type condenser includes first and second header tanks 10 and 20 spaced apart from each other in parallel to each other and a first header tank 10 and a second header tank 20 both ends of which are communicated with the first and second header tanks 10 and 20 A plurality of tubes 30 forming a core portion 32 provided in the first and second header tanks 10 and 20 and a plurality of tubes 30 interposed between the tubes 30, A plurality of baffles (11, 12, 13, 21, 22, 23) arranged in a zigzag manner to form refrigerant flow paths, a receiver (40) integrally coupled to the second header tank (20) A plurality of connecting pipes 51, 52 and 53 for connecting the second header tank 20 and the receiver 40 so as to communicate with each other, a refrigerant inlet pipe 61 installed at one side of the first header tank 10, And a refrigerant outflow pipe 62 provided in a subcool area S of the first header tank 10.

The core portion 32 is formed by a superheat removing and condensing region H through which a gaseous refrigerant of high temperature and high pressure flowing through the refrigerant inflow pipe 61 passes and a condensing region C where the gaseous refrigerant is condensed by gas- A pre-subcool area (PS) in which the liquid refrigerant is supercooled in advance, and a subcool area (S) in which the liquid refrigerant is supercooled and discharged to the outside. The condensing region C is divided into a first condensing region C1 and a second condensing region C2 step by step and the sub-cool region S is divided into a first sub-cool region S1 and a second sub- And a sub-cool region S2.

In the conventional condenser 1 integrated with a receiver as described above, the flow path of the refrigerant is as follows. The high temperature and high pressure refrigerant flowing through the refrigerant inflow pipe 61 provided at the substantially central portion of the first header tank 10 is superheated while passing through the superheat removing and condensing region H, .

Next, the refrigerant having passed through the superheat eliminating and condensing region (H) is subjected to gas-liquid separation in the second header tank (20). That is, the relatively gaseous refrigerant floats upward and flows through the first condensing region C1 and the second condensing region C2 partitioned by the baffles 11 and 21 while flowing in a serpentine, and is heat-exchanged with the outside air to be condensed , And moves to the receiver (40) through the connecting pipe (51).

On the other hand, the relatively liquid refrigerant flows downward by the action of gravity and flows sequentially in the free sub-cool region PS and the first sub-cool region S1 defined by the baffles 12, 13, And is then supercooled and transferred to the receiver (40) through the connecting pipe (52).
