Flow control valve and air conditioner for vehicle using same

The present invention relates to a flow control valve and a vehicle air conditioner using the same, and more particularly, a flow control valve capable of adjusting the amount of the heat exchange medium and the amount of bypass that are introduced into the heat exchange medium necessary part according to a user's temperature setting; The present invention relates to a flow control valve capable of increasing cooling and heating efficiency and a vehicle air conditioner using the same.

In recent years, interest in the environment and energy has been increasing worldwide in the automobile industry, and studies for improving fuel efficiency have been made. Research and development for lightening, miniaturization and high performance are continuously carried out in order to satisfy the needs of various consumers. In particular, in the vehicle air conditioning system, since it is difficult to secure sufficient space in the engine room, the vehicle air conditioner is required for the vehicle air conditioner that can effectively control the temperature and air volume while being compact.

In general, a vehicle air conditioner is a device that maintains the interior of a car at an appropriate temperature in summer or winter, or removes frost that is stuck on the windshield of a car during rainy or winter seasons, so as to secure the driver's front and rear views. The air outside the vehicle introduced into the vehicle interior is passed through the evaporator or heater core through which the coolant flows, and is distributed to various directions of the vehicle interior in the cold or warm state through a vent connected to each part of the vehicle interior. It is.

1 is a cross-sectional view illustrating an example of a conventional vehicle air conditioner. Referring to FIG. 1, the conventional vehicle air conditioner includes a vent 11 whose opening degree is adjusted by respective doors 11d, 12d, and 13d. , 12, 13 and the air conditioning case 10 is installed; A blower unit 14 connected to an air inlet of the air conditioning case 10 to blow outside air; An evaporator (E) and a heater core (H) provided in the air conditioning case (10); The air conditioning case 10 is characterized in that it comprises a temporal door 15 for adjusting the opening degree of the cold air passage (P1) and the warm air passage (P2).

In the conventional vehicle air conditioner configured as described above, when the cooling cycle is operated, the temporal door 15 opens the cold air passage P1 and closes the warm air passage P2. Therefore, the air blown by the blower 14 is exchanged with the cooling water flowing through the evaporator E while passing through the evaporator E, and is converted into cold, and then flows and opens toward the cold air passage P1. Cooling of the vehicle interior is performed by discharging the vehicle interior through the vents 11, 12, 13.

In addition, when the heating cycle is activated, the temporal door 15 closes the cold air passage P1 and at the same time, the air blown by opening the warm passage P2 is heated by the heater passage P2. Heat is exchanged with the coolant flowing through the inside of the heater core (H) to change the warmth and discharged to the interior of the vehicle through the open vent (11, 12, 13) is carried out through the core (H) is carried out .

Figure 2 is a perspective view showing a conventional heater core (H) has shown two representative forms of a conventional heater core (H), Figure 2 (a) shows a heater core of the U-turn type and the figure 2 (b) shows a one-way type heater core. Referring to FIG. 2, the conventional heater cores H will be described in more detail. The conventional heater cores H may be spaced apart from each other by the first header tank 21 and the second header tank 22. , An inlet pipe 25 connected to the first header tank 21 or a second header tank 22, an inlet pipe 25 through which the heat exchange medium is introduced, and an outlet pipe 26 through which the heat exchange medium is discharged, and the first header tank 21. And a plurality of tubes 23 fixed at both ends to the second header tank 22 to form a heat exchange medium flow path, and pins 24 interposed between the tubes 23; .

1 and 2, the same components as those of the heater core of the present invention and the vehicle air conditioner to which the heater core is mounted have the same reference numerals.

However, the conventional vehicle air conditioner configured as described above has a temporal door which adjusts the opening degree of the cold air passage and the warm air passage when the evaporator and the heater core are fixed at a specific position, and cools and heats as much as the moving radius of the temp door. Since the space inside the engine room must be taken and the structure is complicated, the air flow is disturbed, so it is difficult to expect a proper amount of air and there is a big noise.

In addition, since the conventional heater core cannot adjust the amount of cooling water introduced into the heater core, even when a cooling cycle is operated, the temp door closes the warm passage as the high temperature cooling water continues to flow into the heater core. Even if the air is not introduced into the warm passage, the temperature of the air is increased by the high temperature cooling water, which makes it difficult to effectively cool the air.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to accurately adjust the amount of heat exchange medium flowing into the heat exchange medium required portion according to the user's temperature setting using a plate-shaped valve, heat exchange medium It provides a flow control valve that can minimize the risk of leakage, and can easily adjust the temperature of the vehicle interior by using the flow control valve, it is not necessary to be equipped with a temp door can use the vehicle space more efficiently In addition, the flow control valve and the auxiliary door can be interlocked to provide a flow control valve that can increase the cooling and heating efficiency of the air conditioning device and a vehicle air conditioning apparatus using the same.
