Description

Condenser for Vehicles {Condenser for motor vehicle}

The present invention relates to a condenser having a sub-cooling portion (sub-cool) formed thereon and comprising a receiver drier. More specifically, in the receiver dryer, to add a fixing cap located at the bottom of the refrigerant riser to prevent breakage, noise or leakage of refrigerant due to the flow of the refrigerant riser coupled to the bottom of the partition plate. All.

In general, a condenser is a high-temperature, high-pressure gaseous refrigerant flows into the liquid state while releasing liquefied heat by heat exchange, and is discharged. In this process, a gaseous refrigerant (hereinafter referred to as a 'gas refrigerant') and a liquid state Refrigerants (hereinafter referred to as "liquid refrigerants") are mixed. At this time, it is preferable to induce supercooling by separating the condensed liquid refrigerant and the uncondensed gaseous refrigerant and performing recondensation. A receiver dryer is provided at one side thereof.

On the other hand, when the sub-cooling area of the condenser is located at the bottom, it is covered by a peripheral material such as a bumper beam, so that there is a problem in that the subcooling efficiency is lowered. The condenser has been disclosed.

1 shows a conventional receiver drier connected to an upper subcooled (or upper subcooled) condenser. Referring to FIG. 1, the refrigerant rise pipe 130 ′ is coupled to the communication hole 122 ′ eccentrically formed from the center of the partition plate 120 ′. The communication hole and the coolant riser are provided eccentrically to accommodate the drying material 140 'taking up a predetermined volume, and the drying material serves to remove moisture contained in the refrigerant.

On the other hand, the lower end of the refrigerant riser is in a state spaced apart from the upper surface of the lower cap 180 '. That is, the refrigerant introduced from the lower connector 112 'in communication with the lower condensation region is deposited on the upper surface of the lower cap 180', which is the lower region of the partition plate 120 ', thereby being referred to as a gaseous refrigerant (hereinafter referred to as' gas refrigerant'). ) And a liquid refrigerant (hereinafter referred to as a 'liquid refrigerant'), and a portion of the liquid refrigerant rises through the refrigerant inlet 133 'of the refrigerant riser 130'. Subsequently, foreign matter is filtered through the filter 160 ′ positioned above the partition plate 120 ′, and only the liquid refrigerant separated through the upper connector 114 ′ into the subcooling region is sent.

According to the above-described prior art, the lower end of the refrigerant riser 130 'flows due to the pressure or external impact of the refrigerant flowing through the lower connector 112'. In particular, noise may be generated when it hits the inner wall of the receiver dryer due to the flow, and the coupling part of the partition plate 120 'and the refrigerant riser 130' may be damaged, causing the refrigerant to leak, thereby performing a desired function. There is a problem that there is no.
