[0002] A condenser is a device in a vehicle air conditioning system that releases the heat from compressed refrigerant gas using coolant. Hot refrigerant gas condenses into a liquid state as it exchanges heat with the coolant inside the condenser. It has the advantage of superior cooling efficiency compared to air-cooled condensers and provides effective cooling even in hot environments.
[0003] FIG. 1 is a cross-sectional view of a structure in which a conventional connector and a receiver dryer are connected. Referring to FIG. 1, the condenser (10) is formed by stacking a plurality of plate-shaped plates, and refrigerant and cooling water are alternately introduced and flowed into the space between each plate, and heat exchange proceeds. The refrigerant is condensed into a liquid state through heat exchange with the cooling water, and the condensed refrigerant is supplied to the receiver dryer (20) through the first connector (31). After the refrigerant passes through the receiver dryer to remove moisture and impurities, it is supplied to the SC (subcooling) region of the condenser through the second connector (32) to form a lower temperature.
[0004] Conventional condensers are configured with a first flow path through which the refrigerant flows toward the receiver dryer and a second flow path through which it is supplied from the receiver dryer to the SC area. This interconnected structure has the disadvantage of reducing the surface area for heat exchange between the refrigerant and the cooling water. The problem to be solved
[0005] Accordingly, this embodiment was devised to solve the problems described above, and presents a connector and a capacitor including the same that increase the heat transfer area and heat exchange efficiency by modifying the existing two-way connection structure. means of solving the problem

[0009] Additionally, the condenser comprises a refrigerant inlet for refrigerant inflow and a refrigerant outlet for refrigerant discharge, a connection portion formed toward a receiver dryer, a plate having a plurality of through holes formed to allow refrigerant flow, and a separator plate arranged to separate a condensation area and a sub-cooling area; a connector comprising an outer casing connected at one end to the connection portion and coupled at the other end to a receiver dryer, an inner tube disposed inside the outer casing, and a partition wall connected at one end to the inner surface of the outer casing and at the other end to the outer surface of the inner tube to fix the position of the inner tube, and a communication tube inserted at one end into the inner tube and at the other end connected to the connection hole of the separator plate to communicate between the receiver dryer and the sub-cooling area.
[0010] In addition, the above-mentioned connecting pipe is characterized in that the inner diameter of the inner pipe and the diameter of the connecting hole correspond to each other, and it is positioned to pass through the connecting passage formed by the through hole of the plate.
[0011] In addition, the diameter of the connecting channel is formed to be larger than the diameter of the connecting pipe and corresponds to the diameter of the through hole.
[0012] Additionally, the connector includes an outer hole formed between the outer tube and the inner tube to allow the refrigerant to flow from the condenser toward the receiver dryer.
[0013] In addition, the cross-sectional area of the outer hole is formed to be larger than the cross-sectional area of the inner tube.
[0014] In addition, the above bulkhead is characterized by being arranged in the longitudinal direction at equal angles.
[0015] Additionally, the connector includes a block formed on the outer surface of the exterior and positioned to be in contact with the capacitor and the receiver dryer.
[0016] Additionally, the above exterior includes an extension formed by extending in the longitudinal direction such that one end contacts the internal configuration of the receiver dryer and the other end contacts the internal configuration of the condenser. Effects of the invention

[0022] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the invention to specific embodiments, and it should be understood that it includes all modifications that fall within the spirit and scope of the invention.
[0023] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which this invention pertains.
[0024] Terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.
[0025] Hereinafter, an embodiment of the present invention, a dual connector and a capacitor including the same, will be described in detail with reference to the attached drawings.
[0026] FIG. 2 is a structural diagram of the present invention. Referring to FIG. 2, a capacitor (100) and a receiver dryer (200) are connected through a connector (300) and formed as a single unit through brazing.
[0027] A condenser (100) includes a refrigerant inlet (101) into which refrigerant is introduced, a refrigerant discharge (102) into which refrigerant is discharged, and a connection portion formed to allow the refrigerant to flow between the condenser (100) and the receiver dryer (200). The refrigerant is introduced through the refrigerant inlet (101) and flows to the receiver dryer (200) through a connector (300) coupled to the connection portion. Subsequently, it is introduced into the condenser (100) through the connection portion and discharged to the outside through the refrigerant discharge portion (102). The present invention is characterized by the refrigerant entering and exiting the condenser (100) and the receiver dryer (200) through a single connection portion (103).
[0028] A condenser (100) is formed by stacking a plurality of plates (110). A flow path is formed through a plurality of through holes and folded portions formed in the plates (110) of the condenser (100), through which refrigerant or cooling water flows. As the refrigerant and cooling water flow, heat exchange takes place. Between the plurality of plates (110), a separator plate (120) is formed, having one or more through holes through which cooling water flows and one connecting hole (121) through which refrigerant flows. By forming only one connecting hole through which the refrigerant flows, the direction of refrigerant flow is controlled. Based on the separator plate (120), the side where the inlet is formed is divided into a condensation area (A), and the side where the outlet is formed is divided into a subcooling area (B). Hereinafter, the subcooling area will be abbreviated as the SC area.
[0029] The condenser (100) and the receiver dryer (200) are connected through a connector (300). The connector (300) consists of an outer tube and an inner tube, and two types of holes are formed. It includes an outer hole formed between the outer tube and the inner tube, and an inner hole formed in the inner diameter of the inner tube. The outer hole allows the refrigerant to flow from the condenser to the receiver dryer, and the inner hole allows the refrigerant to flow from the receiver dryer to the condenser.
[0030] The receiver dryer (200) removes foreign substances from the refrigerant and removes moisture. A connecting pipe (400) connecting the receiver dryer (200) and the SC area (B) is disposed in the inner hole. The refrigerant processed in the receiver dryer (200) flows into the SC area (B) through the connecting pipe (400). This has the advantage that the processed refrigerant is not affected by the refrigerant and cooling water in the condensation area (A).
[0031] In addition, the present invention has the advantage of expanding the heat exchange area between the refrigerant and the cooling water within the condensation zone by configuring the connecting structure connected to the receiver dryer as a single unit.
[0032] FIG. 3 is a perspective view of a connector. Referring to FIG. 3, the connector (300) is formed with an outer casing (310), an inner tube (320), and partitions (330). An inner tube (320) is positioned inside the outer casing (310). The outer casing (310) and the inner tube (320) are positioned to face in the same direction, and a plurality of partitions (330) are positioned in the space between the outer casing (310) and the inner tube (320). One end of the partition (330) is connected to the inner surface of the outer casing (310), and the other end of the partition (330) is connected to the outer surface of the inner tube (320). The inner tube (320) is fixed to the center inside the outer casing (310) by the partitions (330). The partitions (330) are positioned at equal angles inside the outer casing (310).
[0033] The connector (300) has two types of holes formed by the outer tube (310) and the inner tube (320). The outer hole (311) refers to the space between the outer tube (310) and the inner tube (320), and the inner hole refers to the hole formed in the center of the inner tube (320).
[0034] The connector (300) connects the condenser and the receiver dryer. The outer hole (311) allows the refrigerant to flow from the condenser (100) to the receiver dryer (200). A connecting pipe (400) is inserted into the inner hole. The end of the connecting pipe (400) is connected to the SC region. The refrigerant flows from the receiver dryer to the condenser through the connecting pipe (400).
[0035] To ensure smooth refrigerant flow, the design incorporates a difference in cross-sectional area between the outer hole and the inner tube. Refrigerant passing through the outer hole has a relatively lower density and higher flow velocity, while refrigerant passing through the inner tube has a relatively higher density and lower flow velocity. Considering the state of the refrigerant, the refrigerant passing through the outer hole has a lower density and higher flow velocity; therefore, the present invention is characterized by the outer hole having a larger cross-sectional area than the inner tube. At this time, the inner hole is designed taking into account the diameter of the connecting tube through which the refrigerant actually flows.
[0036] The connector (300) includes a block (312) formed on the outer surface of the exterior (310) and positioned to be in contact with the capacitor and the receiver dryer. The block (312) is formed to protrude from the outer surface of the exterior (310). One side of the block (312) is in contact with the receiver dryer, and the other side is in contact with the capacitor. One side may be formed as a curved surface to be in contact with the receiver dryer.
[0037] The receiver dryer (200) and the condenser (100) are maintained at a certain distance from each other by the block (312), and the ease of connection is improved. At this time, a separate sealing member may be additionally placed in the connector (300) to prevent refrigerant from leaking out.
[0038] FIG. 4 is a perspective view of the present invention. Referring to FIG. 4, the condenser (100) includes a refrigerant inlet (101) into which refrigerant flows, a refrigerant discharge (102) into which refrigerant is discharged, a connection (103) formed toward a receiver dryer (200), a plate having a plurality of through holes formed to allow refrigerant to flow, and a separator plate arranged to separate a condensation area and an SC area. The condenser (100) includes an outer casing, one end of which is connected to the discharge port and the other end of which is connected to the receiver dryer (200), an inner tube arranged inside the outer casing, and a connector (300) including a partition wall, one end of which is in contact with the inner surface of the outer casing and the other end of which is in contact with the outer surface of the inner tube so that the position of the inner tube is fixed. The connector (300) includes a connecting tube, one end of which is inserted into the inner tube and the other end of which is connected to the connection hole of the separator plate so that the receiver dryer (200) and the SC area are in communication.
[0039] The condenser (100) is formed by stacking plate-shaped plates, and cooling water and refrigerant flow alternately in the space formed by the plates. The condenser (100) includes a refrigerant inlet (101) into which refrigerant flows into the interior of the condenser (100), a refrigerant outlet (102) into which refrigerant is discharged to the outside of the condenser (100), a connection part (103) into which refrigerant flows between the condenser (100) and the receiver dryer (200), a cooling water inlet (104) into which cooling water flows, and a cooling water outlet (105) into which used cooling water is discharged.
[0040] A refrigerant inlet (101), a cooling water discharge (105), and a connection (103) are formed on one side of the condenser (100), and a refrigerant discharge port (102) and a cooling water inlet (104) are formed on the other side of the condenser (100). By flowing the refrigerant and the cooling water in opposite directions, the low-temperature refrigerant can be effectively discharged.
[0041] FIG. 5 is a cross-sectional view of the present invention based on the refrigerant inlet. Referring to FIG. 5, the condenser (100) has a plurality of plates (110) stacked, and a flow path through which refrigerant or cooling water flows is formed by protrusions and through holes formed on the plates (110).
[0042] A condenser (100) has covers placed on both sides with a stacked plate (110) in between. A first cover (106) placed on one side has a refrigerant inlet (101), a cooling water outlet (105), and a connection part formed therein, and a second cover (107) placed on the other side has a refrigerant outlet (102) and a cooling water inlet formed therein.
[0043] Refrigerant is introduced into the condenser through the refrigerant inlet (101), passes through the receiver dryer, and is discharged through the refrigerant outlet (102). The refrigerant inlet (101) and the refrigerant outlet (102) are aligned on the same line, and a flow path is formed so that the refrigerant passes through the receiver dryer by a separator plate. A detailed explanation of the flow of the refrigerant will be provided later.
[0044] FIG. 6 is a cross-sectional view of the present invention based on the connection portion. Referring to FIG. 6, the capacitor (100) is connected to the receiver dryer (200) through the connector (300).
[0045] A capacitor (100) is formed by stacking multiple plates, and a flow path is formed by through holes and protrusions formed in the plates. The capacitor (100) is divided into a condensation area (A) and an SC area (B) based on one of the multiple plates. Hereinafter, the plate (110) separating the condensation area (A) and the SC area (B) will be described as a separator plate (120).
[0046] In the condensation zone (A), the supplied refrigerant condenses by exchanging heat with the cooling water and flows to the receiver dryer (200) through the connector (300). The refrigerant processed in the receiver dryer (200) flows to the SC zone (B) through the connecting pipe (400) connected to the connector (300). In the SC zone, the refrigerant is cooled to a lower temperature and discharged.
[0047] A refrigerant flow path is formed at the bottom of the condenser (100) toward the receiver dryer (200). This refrigerant flow path is referred to as the connecting flow path (111) for description. The connecting flow path (111) is formed larger than the diameter of the connecting pipe and corresponds to a through hole formed in the plate.
[0048] The refrigerant flowing through the connecting channel (111) is supplied to the receiver dryer (200) through the outer hole of the connector (300). At this time, the present invention includes a connecting pipe (400) positioned through the connecting channel (111) to allow the refrigerant processed in the receiver dryer (200) to flow into the SC region (B).
[0049] One end of the connecting pipe (400) is inserted into the inner tube of the connector (300), and the other end is inserted into the connection hole of the separator plate (120). The refrigerant flows through the connecting pipe (400) to the SC region (B) and is not affected by the refrigerant and cooling water in the condensation region (A).
[0050] The connecting pipe (400) corresponds to the inner pipe (320) of the connector (300) and the connecting hole of the separator plate (120). At this time, the diameter of the connecting pipe (400) is formed to be smaller than that of the connecting passage (111). Through this, the refrigerant flows to the receiver dryer (200) through the space between the connecting passage (111) and the connecting pipe (400).
[0051] The refrigerant that flows through the connecting pipe (400) into the SC region (B) is cooled to a lower temperature through heat exchange with the cooling water, and then discharged to the outside through the refrigerant discharge section (102).
[0052] FIG. 7 is an enlarged view of FIG. 6. Referring to FIG. 7, the capacitor (100) and the receiver dryer (200) are connected by a connector (300). Specifically, one end of the connector (300) is inserted into and connected to the receiver dryer (200), and the other end of the connector (300) is inserted into and connected to the connection part (103) of the capacitor (100).
[0053] A protruding block (312) is formed on the outer surface of the connector (300). The connection part (103) of the condenser (100) is formed protruding from the first cover (106). The condenser (100) and the connector (300) are connected so that the connection part (103) contacts the other side of the block (312) to prevent the refrigerant from leaking out. One side of the block (312) is positioned to contact the receiver dryer (200).
[0054] The connector (300) consists of an outer tube and an inner tube. A connecting tube (400) is inserted into the inner tube. The refrigerant is transferred from the condenser (100) to the receiver dryer (200) through an outer hole (311) formed between the outer tube and the inner tube, and from the receiver dryer (200) to the condenser (100) through the connecting tube (400).
[0055] The diameter of the connecting pipe (400) is formed to be smaller than the through hole formed in the plate, so that the refrigerant can flow smoothly.
[0056] FIG. 8 is a modified embodiment of a connector. Referring to FIG. 8, the outer surface (310) of the connector (300) includes an extended portion (C) that is extended in the longitudinal direction. The inner tube (320) can be modified to be shortened in the longitudinal direction.
[0057] By extending the length of the outer casing (310), it is positioned so that one end contacts the internal configuration of the receiver dryer (200) and the other end contacts the internal configuration of the condenser (100). Through this, the connector (300) has the advantage of increasing the bonding strength with the condenser (100) and the receiver dryer (200). In addition, it has the advantage of providing straightness so that the refrigerant flowing from the condenser (100) to the receiver dryer (200) does not flow in a different direction.
[0058] The length of the inner tube (320) is modified to be relatively shorter. By shortening the length of the inner tube (320), there is an advantage in that the internal space of the receiver dryer (200) is secured.
[0059] The present invention is not limited to one embodiment and has a diverse scope of application. Furthermore, it is understood that various modifications are possible without departing from the essence of the invention as claimed in the claims. Explanation of the symbols
