Description

Evaporator and vehicle air conditioner using the same {Evaporator And Air conditioner for an Automobile}

The present invention relates to an evaporator and a vehicle air conditioner using the same, and improves assembly by removing a protrusion formed on the side of the evaporator as the inlet pipe and the outlet pipe are formed by attaching a separate coupling member to the side plate. The present invention relates to an evaporator capable of preventing air from leaking between air conditioning cases and a vehicle air conditioner using the same.

An air conditioner of a vehicle is a device for cooling or heating an interior of a vehicle by introducing external air into a vehicle interior or by heating or cooling the air in a vehicle interior. In addition, the heater core and a device for selectively blowing air cooled or heated by the evaporator or the heater core to the respective parts of the vehicle interior using the blowing mode switching door.

According to the independent structures of the blower unit, the evaporator unit, and the heater core unit, the air conditioner includes a three-piece type in which the three units are independently provided, an evaporator unit, and a heater core unit in the air conditioning case, and the blower unit. Is divided into a semi-center type provided as a separate unit, and the center mounting type in which all three units are built in the air conditioning case.

1 is a schematic view showing an example of a conventional vehicle air conditioner, as shown in the conventional vehicle air conditioner 300, the internal air inlet 321 and the outdoor air inlet 322 is formed on one side, the inside, outside air Internal and external air conversion doors 323 are installed to selectively open and close the inlets 321 and 322, and include a blower fan 335 for forcibly blowing internal and external air to the air inlet 343 of the air conditioning case 340. And an air inlet 343 through which the air blown from the blower 310 is introduced, and an air outlet 344 through which the air is discharged. 341 and the air conditioning case 340 provided with the heater core (H). Here, the internal and external air conversion door 323 has various forms such as a plate type, a dome type, a cylindrical shape, and a hemispheric shape, which receive less air pressure, depending on the purpose.

FIG. 2A is a perspective view illustrating a conventional semi-center type vehicle air conditioner, and FIG. 2B is a view illustrating an evaporator assembly process of the vehicle air conditioner illustrated in FIG. 2A, and the conventional vehicle air conditioner 300 includes air at an inlet side. An air inlet 343 is formed and the air inlet and the outside air are selectively introduced through the air-conditioning case 340 having a plurality of air outlets 344 formed on the outlet side, and the inside and outside air inlets 322 formed on the upper side. It is composed of a blower 310 forcibly blown to the side (343).

In addition, an evaporator 270 and a heater core (not shown) are sequentially provided inside the air conditioning case 340, and a temperature control door (not shown) for controlling temperature and various inside the air conditioning case 340 is provided. Mode doors (not shown) for performing the air conditioning mode are installed.

The evaporator 270 has an inlet pipe 230 and an outlet pipe 240 protrudingly formed on one side of the evaporator 270 to allow the refrigerant to flow in or out, and at the ends of the inlet pipe 230 and the outlet pipe 240, The flange is coupled to the refrigerant pipe (not shown).

According to the air conditioning apparatus 300 as described above, the air blown into the air conditioning case 340 by the operation of the blower 310 passes through the evaporator 270 and the air passes through the heater core by the temperature control door. In the process of selectively passing through the cooling or heating, the cooled or heated air is supplied to the interior of the vehicle through each duct (not shown) connected to the plurality of air outlets 344 to perform cooling or heating.

Meanwhile, when the vehicle air conditioner system is operated, condensed water is generated around the evaporator 270 during the heat exchange process with the outside air because the coolant circulates inside the evaporator 270. In addition, the evaporator 270 is provided with an inlet pipe 230 connected to an outlet refrigerant pipe of a condenser (not shown) and an outlet pipe 240 connected to an inlet refrigerant pipe of a compressor (not shown). Condensed water is also generated in the pipe 230 and the outlet pipe 240.

The condensed water drops down the air-conditioning case 340 by the wind flowing in the gravity direction or blown by the evaporator 270, the inlet pipe 230, or the outlet pipe 240, and then, an air-conditioning case ( 340 is discharged to the outside through the condensate outlet 340d formed in the lower portion.

In addition, the air conditioning case 340 has a structure in which the upper cases 340a and 340b and a separate integrated lower case 340c for preventing the leakage of condensate are typically coupled to each other. As shown in FIG. The evaporator 341 is assembled between the cases 340a and 340b and the lower case 340c. Here, the upper cases 340a and 340b include a left case 340a and a right case 340b.
