Description

Receiver dryer integrated condenser and its assembly method {CONDENSER UNITED WITH RECEIVER DRIER AND THIS ASSEMBLING METHOD}

The present invention relates to a condenser receiver dryer integrated capacitor and a method for assembling the same, wherein a condenser having a receiver dryer for supplying a necessary amount to a expansion valve by supplying a liquefied refrigerant to a cooling load in a condenser of an automobile air conditioner is provided. It is about giving.

The vehicle is equipped with an air conditioning system composed of a heating system and an air conditioning system for the purpose of indoor ventilation to adjust the room temperature to the appropriate state during the summer and winter.

The air conditioner as described above is provided with an air-conditioning duct which is an integral injection assembly, and an air suction door for controlling the inflow of external air and circulation of indoor air and a blower unit for forced ventilation of the air introduced at the side of the air-conditioning duct. It is provided.

An evaporator and a heater core are sequentially disposed in front of the blower unit, and the passage is partitioned by the temperature control door.

The front of the evaporator and the heater core is a configuration in which cold and warm air flows into the room through a vent hole provided on the deflector or the instrument panel connected to the interior of the vehicle by a distribution door.

The air conditioning system used in the above air conditioning system is a compressor that converts the refrigerant into a gas of high temperature and high pressure → a condenser that liquefies the gas of high temperature and high pressure → removes moisture and dust, and can supply the required amount to the evaporator for the cooling load. Receiver dryer that temporarily turns and stores the refrigerant → Expansion valve to make the same shape as frost of low temperature and low pressure to facilitate heat exchange in the evaporator Circulates back to the compressor.

As described above, the conventional receiver drier temporarily storing the refrigerant supplied to the evaporator and removing foreign matters or moisture contained in the refrigerant is installed independently between the capacitor and the expansion valve, thereby reducing space utilization of the engine room.

In particular, by providing a separate bracket or clamp and screw for fixing the receiver dryer to the refrigerant pipe for connecting to the condenser to provide a cause of the cost increase due to the addition of unnecessary parts, as well as to reduce the overall assembly To provide a cause.

Referring to the configuration and operation of the receiver dryer applied to the prior art for solving the problem as follows.

The cylindrical receiver dryer 10 is integrally formed at the side of the tank 13 of the tank assembly 12 as described above when the tank 13 is pressed.

A through hole 18 is formed on the receiver dryer 10 integrally formed with the tank assembly 12 so as to allow the refrigerant to flow with the tank 13, and a desiccant (not shown) is provided inside the receiver dryer 10. Inserted, the cover 19 for sealing is welded to the upper and lower sides.

As described above, since the receiver dryer 10 is integrally formed on the tank 13 of the tank assembly 12 constituting the capacitor 1, a refrigerant pipe for connecting the capacitor 1 and the receiver dryer 10 is required. There is no need for a separate component to fix the receiver dryer 10.

However, after the desiccant is inserted into the receiver dryer 10, a cumbersome assembling operation for sealing the cover 19 is added. After the desiccant is inserted into the receiver dryer 10, the cover 19 is inserted. After brazing, there was a problem that the desiccant is damaged.

The present invention has been made to solve the above problems, the upper cap and the connector is inserted into the receiver dryer is formed integrally on the tank side of the tank assembly constituting the condenser, the tank is connected to the header and the condenser core At the same time, after brazing, the drying control assembly is inserted and sealed to prevent the drying agent from being damaged during brazing and is installed so that no additional welding is required for the closing of the cap after the desiccant is inserted to remove moisture contained in the refrigerant. By performing faithfully, it improves the quality performance of the receiver driver integrated condenser and improves the assembly and productivity. Also, the outlet fitting with the stud bolt for connecting to the expansion valve is mounted on the fitting mating surface for further assembly. The purpose is to improve.
