Description

Evaporator {EVAPORATOR}

In the dual evaporator in which the refrigerant flows in the first and second rows, a flow portion capable of flowing the refrigerant separately from the first and second compartments is formed, thereby improving the refrigerant flow path configuration, And an inlet and an outlet are provided in each of the second columns.

Background Art [0002] A vehicle air conditioner is an automobile interior product installed for the purpose of enabling a driver to secure front and rear vision by removing air from the windshield during rainy weather or winter season by cooling or heating the interior of the automobile in the summer or winter season, Such an air conditioner usually has a heating system and a cooling system at the same time so that the outside air or the inside is selectively introduced to heat or cool the air and then air is blown into the interior of the automobile to cool,

A typical refrigeration cycle of such an air conditioner is composed of an evaporator for absorbing heat from the surroundings, a compressor for compressing the refrigerant, a condenser for releasing heat to the surroundings, and an expansion valve for expanding the refrigerant. In the cooling system, the gaseous refrigerant flowing into the compressor from the evaporator is compressed to a high temperature and a high pressure in the compressor, and the refrigerant in the gaseous state in the condensed state is discharged while being liquefied while passing through the condenser, The refrigerant passes through the expansion valve again to become a low-temperature and low-pressure humidified vapor state, and then flows into the evaporator again to vaporize and absorb the heat of vaporization from the surroundings, thereby cooling the surrounding air and thereby cooling the interior of the vehicle.

As a representative heat exchanger used in such a cooling system, there have been a lot of studies for more effectively exchanging heat between the air outside the heat exchanger and the heat exchange medium inside the heat exchanger, that is, the refrigerant. The most direct effect of indoor cooling is manifested by evaporator efficiency, and various structural research and development have been conducted to improve the heat exchange efficiency of the evaporator.

One example of an improved structure for enhancing the heat exchange efficiency of the evaporator as described above is an example in which a core made of a tube and a fin has a double evaporation structure in which a first column and a second column, .

[0003] Conventionally, the first and second heat exchangers (not shown) have been used in the prior art as disclosed in Japanese Patent Application Laid-Open No. 2000-062452 ("Vehicle Air-conditioning Apparatus ", 2000.02.29), Japanese Patent Laid-Open Publication No. 2005-308384 A type similar to a double evaporator in which a refrigerant flows independently of heat is disclosed.

An example of the evaporator having the double evaporation structure is shown in FIGS. 1 and 2. FIG. (FIG. 1 is a perspective view of an evaporator, and FIG. 2 is a schematic view of an inner flow of a first column and a second column of the evaporator shown in FIG. 1)

The evaporator 1 shown in FIG. 1 and FIG. 2 is divided into a first compartment 10a and a second compartment 20a in the width direction by partition walls to form a first column and a second column, A first header tank (11) and a second header tank (12) partitioned by first and second compartments (10b, 20b) and including at least one baffle (13) partitioning the space in the longitudinal direction; A first inlet portion 41 connected to one side of the first compartment 10a of the first header tank 11 and through which the refrigerant flowing in the first column flows and a first inlet portion 41 through which the first compartment 10a A first outlet portion 42 connected to the other side of the first outlet portion 42 to discharge the refrigerant; A second inlet 43 connected to the other side of the second compartment 10b of the first header tank 11 to receive the refrigerant flowing in the second heat and a second compartment 10b A second outlet connected to one side of the refrigerant pipe to discharge the refrigerant; A plurality of tubes 20 having both ends fixed to the first header tank 11 and the second header tank 12 of the first header tank 11; And a pin (30) interposed between the tube (20).

2, in the first column, the refrigerant flows into the first compartment 10a of the first header tank 11 through the first inlet portion 41 and flows through the tube 20 Is moved to the first compartment 20a of the second header tank 12 and is again moved to the first compartment 10a of the first header tank 11 through the remaining tube 20, And is discharged through the outlet portion 42.

In the second column, the refrigerant flows into the second compartment 10b of the first header tank 11 through the second inlet 43 and flows into the second compartment 10b of the second header tank 12 through the tube 20. [ Is moved to the second compartment 20b and then moved to the second compartment 10b of the first header tank 11 through the remaining tube 20 and then discharged through the second outlet 20b.

In other words, the evaporator 1 shown in FIG. 1 and FIG. 2 has a separate flow of the refrigerant in the first and second rows. For this purpose, the inlet and the outlet for introducing and discharging the refrigerant into and out of the first and second rows, respectively, (41, 43) and two outlet portions (42, 44).

Accordingly, in the evaporator having the double evaporation structure, since four pipes forming the inlet portion and the outlet portion are connected to each other, the production cost for manufacturing and fixing the evaporator is inevitably increased. Particularly, as shown in FIG. However, when using a separate pipe fixing part for connecting and fixing the pipes, the above problem is more serious.

In addition, the evaporator having the double evaporation structure has a problem that the pipe itself occupies a large space in the engine room, which hinders the miniaturization of the evaporator, and the heat exchange area is reduced accordingly, thereby deteriorating the cooling performance.
