Here, the connecting means may connect the inlet and the outlet formed in the receiver dryer 1 in communication. For example, the receiver dryer 1 and the condenser body 3a may be connected in fluid communication using a connecting means such as a pipe.

Accordingly, the refrigerant supplied from the condenser 3 may be supplied to the condenser 3 again after the liquid refrigerant from which foreign substances are removed is sorted through the receiver dryer 1 . At this time, only the filtered refrigerant supplied from the condenser 3 by the cap 2 with a filter can return to the condenser 3 again.

At this time, the receiver dryer 1 may be integrally formed with at least a part of the condenser 3, but is not necessarily limited thereto. For example, the receiver dryer 1 may be modularized and detachably provided from the condenser 3. In addition, the condenser 3 integrally formed with the receiver dryer 1 may also be modularized and provided to be used in an air conditioning system of a vehicle.

The cap 2 and the receiver tank 10 may form an outer appearance of the receiver dryer 1 .

Referring to FIGS. 3 to 5 , the receiver tank 10 may be formed in a cylindrical shape with an opening formed therein and a space S formed therein. For example, the receiver tank 10 may be formed in an elongated cylindrical shape, but is not necessarily limited thereto. For example, the horizontal cross section may be formed in a polygonal shape such as a quadrangle or a pentagon.

Also, the receiver tank 10 may include an inlet 11 formed at a lower portion and an outlet 12 formed at an upper portion. Here, the refrigerant of the condenser 3 may flow into the space S through the inlet 11 . Then, only the refrigerant in a liquid state from which foreign substances are filtered through the cap 2 of the receiver dryer 1 may be transported back to the condenser 3 through the discharge port 12 .

In addition, an opening may be formed on the upper side of the receiver tank 10 to allow the cap 2 to be coupled thereto. Here, the opening may be called a receiver tank hole or a coupling hole.

Also, a screw thread may be formed on an inner circumferential surface of the opening-side receiver tank 10 . Accordingly, the cap 2 is screwed to the inner circumferential surface of the receiver tank 10 to prevent the refrigerant present in the space S from leaking out through the opening.

Here, as an example, the cap 2 is used as a stopper for blocking the opening, but is not necessarily limited thereto. For example, the cap 2 may be disposed on top of the receiver tank 10 as a screwable lid type.

Meanwhile, on the inner circumferential surface of the receiver tank 10, as shown in FIGS. 3 and 5, a locking protrusion 13 formed to protrude toward the center C may be included.

When the cap 2 is screwed into the receiver tank 10, the locking protrusion 13 supports the lower end of the cap 2 so that the cap 2 reaches a predetermined position. That is, the locking protrusion 13 may be provided as a positioning means for determining the position of the cap 2 .

Also, a moisture absorbing member 20 may be disposed on the lower side of the space S of the receiver tank 10 .

The moisture absorbing member 20 may remove unwanted moisture from the refrigerant. Here, a desiccant may be used as the moisture absorbing member 20 .

In the case of the conventional receiver dryer, the cap is disposed at the lower part, but even if the radiator is disposed on the lower side in front of the condenser 3 based on the vehicle (not shown), the receiver dryer 1 according to the embodiment is detachably attached to the upper part By disposing the cap 2, the positional freedom of the subcool area of the condenser 3 can be secured.

However, since the refrigerant supplied from the condenser 3 may exist as a refrigerant in a gaseous or liquid state together with foreign substances, a structure that selects and filters only the refrigerant in a liquid state is required. Accordingly, the receiver dryer (1) provides a structure of the cap (2) capable of selecting only the filtered refrigerant in a liquid state even when the cap (2) is placed thereon, thereby providing the condenser (3) with the liquid filtered in the condenser (3). Only refrigerant can be supplied.

At this time, the cap 2 may be modularized to be detachably disposed on the receiver tank 10 . Accordingly, the assembly process of the cap 2 is simplified. In addition, when repairing the cap 2 for removing damaged or attached foreign matter, the cap 2 is provided as a separate object to facilitate replacement.

6 is a perspective view showing a cap according to an embodiment, FIG. 7 is an exploded perspective view showing a cap according to an embodiment, FIG. 8 is a front view showing a cap according to an embodiment, and FIG. 9 shows a cap according to an embodiment. it is a cross section Here, FIG. 9 is a cross-sectional view taken along line A-A of FIG. 6 .

6 to 9, the cap 2 according to the embodiment includes a cap part 100 coupled to the receiver tank 10 by a screw coupling method and a partition part 200 coupled to a lower portion of the cap part 100. ) may be included. In addition, the cap 2 further includes a first sealing member 300 disposed outside the cap portion 100 and a second sealing member 400 disposed outside the partition wall portion 220 of the partition portion 200. can do. Here, the outer side may indicate a direction opposite to the direction toward the center C on a plane with respect to the center C, and the inner side may indicate a direction toward the center C. In this case, the center (C) may be the center (C) of the cap (2) or the center (C) of the receiver tank (10).

The cap part 100 can be rotated to be coupled with the receiver tank 10 by screwing, and the partition part 200 is located on the lower side of the cap part 100 to be non-interlocked with the rotation of the cap part 100. can be combined Accordingly, when the cap part 100 rotates to engage or disengage from the receiver tank 10, the partition part 200 linearly moves in the vertical direction. That is, by non-interlocking coupling between the cap part 100 and the partition part 200, the rotational force of the cap part 100 is converted into a pressing force of the partition part 200 in the vertical direction, so that the sealing force by the cap 2 can be improved. .

Therefore, when the cap 2 is screwed into the receiver tank 10, rotation of the pipe 222 of the partition 200 is prevented by non-interlocking coupling between the cap 100 and the partition 200. can Accordingly, interference between the pipe 222 and the moisture absorbing member 20 of the receiver tank 10 can be minimized.

And, since the pipe 222 moves linearly, it is positioned at a predetermined position in the receiver tank 10 based on the radial direction.

The cap part 100 is screwed into the opening of the receiver tank 10 to prevent leakage of refrigerant inside the receiver tank 10 to the outside. And, the cap part 100 may be formed of a synthetic resin material such as plastic.

The cap part 100 includes a cap body 110 coupled to the opening of the receiver tank 10 by screwing, a first groove 120 concavely formed in the lower portion of the cap body 110, and a concave upper portion. A second groove 130 may be included. Here, the first groove 120 may be called a coupling groove, and the second groove 130 may be called a wrench groove or a second groove.

In addition, the cap part 100 may include a protrusion 140 protruding toward the center C from the lower part of the cap part body 110 . Here, the protrusion 140 may be called a separation prevention protrusion or a support protrusion.

Meanwhile, a screw thread may be formed on an outer circumferential surface of the cap body 110 . Accordingly, the screw thread of the cap body 110 may be screwed with the screw thread formed on the inner circumferential surface of the receiver tank 10 .

Also, as shown in FIG. 9 , a first sealing member 300 may be disposed on an outer circumferential surface of the cap body 110 , and an O-ring may be used as the first sealing member 300 .

The coupling portion 210 of the partition portion 200 may be coupled to the first groove 120 in a non-interlocking manner with rotation of the cap body 110 . And, to prevent the coupling portion 210 from being separated from the first groove 120 , the cap portion 100 may include a protrusion 140 to support the lower side of the coupling portion 210 .

As shown in FIGS. 7 and 9 , the second groove 130 may be concavely formed in the upper center of the cap body 110 .

In addition, a portion of a fastening tool such as a hexagonal wrench may be coupled to the second groove 130 for screwing. Accordingly, the cap body 110 can be rotated by the fastening tool.

The partition part 200 includes a coupling portion 210 disposed in the first groove 120 and a partition wall portion ( 220), which is disposed between the coupling part 210 and the partition wall part 220 and is disposed below the filter part 230 including the filter 232 and the partition wall part 220 to form the hole 221a. It may include a pipe 222 extending the flow path. In this case, the upper side of the hole 221a may be disposed to communicate with the inside of the filter unit 230 .

Here, the coupling part 210, the partition wall part 220, and the filter part 230 may be integrally formed. And, as shown in FIG. 9 , the pipe 222 may be integrally formed with the partition wall portion 220, but is not necessarily limited thereto.

The coupling part 210 may be coupled to the first groove 130 . At this time, the coupling part 210 may be disposed on the cap body 110 so as not to interlock with the rotation of the cap part 100 .

The coupling part 210 may be formed in a plate shape to cover the filter part 230 .

However, if foreign substances are attached to the filter 232 of the filter unit 230, since overpressure may be formed inside the filter unit 230, the coupling unit 210 has a ring shape as shown in FIG. can be formed as Accordingly, when the overpressure occurs, the refrigerant in a liquid state leaks through the gap between the cap part 100 and the coupling part 210 to effectively respond to the overpressure.

Meanwhile, an inclined surface 211 may be formed on an outer circumferential surface of the coupling part 210 formed in a ring shape.

The inclined surface 211 minimizes interference with the protrusion 140, so that the coupling part 210 can be easily disposed in the first groove 130. The inclined surface 211 may be formed by cutting the outer circumferential surface obliquely, and accordingly, the thickness of the coupling part 210 in the radial direction may decrease toward the upper side.

The partition wall portion 220 is disposed so that the lower side of the coupling portion 210 is spaced apart from each other.

Referring to FIG. 4 , the partition wall portion 220 may divide the space S formed inside the receiver tank 10 into upper and lower portions. For example, due to the arrangement of the partition wall portion 220, the space (S) includes a lower non-filtering space (S1) in which liquid or gaseous refrigerant exists and an upper filtering space (S2) for filtering foreign substances. can be distinguished. Here, based on the position of the filter 232, the filtration space (S2) is a pre-filtration space (S2a) in which only the refrigerant in a liquid state before filtration exists and a filtration space (S2a) in which only the refrigerant in a liquid state from which foreign substances are removed after filtration exists. It can be divided into the back space (S2b).

Also, the non-filtering space S1 may communicate with the inlet 11 of the receiver tank 10, and the post-filtering space S2b may communicate with the outlet 12. And, the pre-filtration space (S2a) of the non-filtering space (S1) and the filtering space (S2) may communicate with each other through a hole (221a) and a pipe (222).

Therefore, only the liquid refrigerant among the liquid and gaseous refrigerants in the non-filtering space S1 moves to the pre-filtration space S2a through the hole 221a and the pipe 222, and moves to the pre-filtration space S2a. ) The refrigerant in a liquid state is filtered through the filter 232 and moved to the post-filtering space S2b.

A second sealing member 400 may be disposed on an outer circumferential surface of the partition wall portion 220 . Accordingly, the gaseous refrigerant present in the non-filtering space S1 is prevented from leaking into the post-filtering space S2b of the filtering space S2. Here, an O-ring may be used as the second sealing member 400 .

Referring to FIG. 9 , the partition wall part 220 is disposed below the partition body 221 and the partition body 221 through which the hole 221a is formed in the vertical direction to provide a passage through the hole 221a. It may include an extending pipe 222 . In this case, an upper portion of the hole 221a may be disposed to communicate with the inside of the filter unit 230 . Here, the hole 221a may be called a partition wall hole or a through hole.

The pipe 222 may be formed long with a predetermined length (L) based on the lower end of the partition body 221 . In this case, the lower end of the pipe 222 may be spaced apart from the inner bottom surface of the receiver tank 10 . Accordingly, only the liquid refrigerant existing in the non-filtering space S1 may move to the pre-filtering space S2a through the pipe 222 .

Here, since the pipe 222 is disposed to communicate with the lower portion of the hole 221a, the passage formed by the hole 221a can be extended.

As shown in FIG. 9 , the pipe 222 may be integrally formed with the bulkhead body 221, but is not necessarily limited thereto.

10 is a view illustrating a pipe detachably disposed in a partition wall portion of a cab according to an embodiment.

Referring to FIG. 10 , the pipe 222 may be detachably disposed under the partition wall portion 220 .

The pipe 222 may be damaged due to chemical action of the moisture absorbing member 20 inside the receiver tank 10 . Accordingly, when a case in which liquid refrigerant cannot be transported through the pipe 222 occurs, replacement of the pipe 222 may be required. Therefore, by detachably coupling the pipe 222 to the bulkhead body 221, it is possible to easily replace the pipe 222.

Meanwhile, the pipe 222 may be disposed eccentrically with the center C of the partition wall portion 220 . As shown in FIGS. 9 and 10 , the pipe 222 may be arranged to have a predetermined distance d from the center C of the partition 220 in the radial direction. Accordingly, since the pipe 222 is disposed far from the inlet 11 formed in the receiver tank 10, the refrigerant flowing into the receiver tank 10 through the inlet 11 is in contact with the moisture absorbing member 20. quantity is improved.

The filter unit 230 may include a plurality of frames 231 disposed to be spaced apart from each other between the coupling unit 210 and the partition wall unit 220 and a filter 232 disposed between the frames 231 .

The frame 231 supports the filter 232 to prevent the filter 232 from being separated by the refrigerant.

The frame 231 may be formed in a bar shape disposed in a vertical direction.

The plurality of frames 231 may be disposed to be spaced apart from each other along the circumferential direction based on the center (C). At this time, the frame 231 may be spaced apart from the center (C) in the radial direction.

The frame 231 may be integrally formed with the coupling part 210 and the partition wall part 220 . As the cap part 100 rotates, the coupling part 210, the filter part 230, and the partition wall part 220 move linearly together.

The filter 232 may be disposed between the frames 231 to filter foreign substances included in the refrigerant in a liquid state.

A mesh or screen material may be used as the filter 232, and the mesh may be provided in a lattice structure in which a plurality of openings are formed.

Referring to FIG. 7 , the horizontal section of the filter 232 may be formed in an arc shape. Accordingly, when the foreign matter is filtered out, the contact area with the refrigerant is increased so that the foreign matter can be effectively removed.

The first sealing member 300 is disposed on the cap portion 100 of the cap 2 to prevent the refrigerant inside the receiver dryer 1 from being discharged to the outside.

The second sealing member 400 is disposed on the partition wall portion 220 of the cap 2 to prevent the gaseous refrigerant present in the non-filtering space S1 from leaking upward. Accordingly, the second sealing member 400 is provided as a component that divides the space S of the receiver tank 10 into a non-filtering space S1 and a filtering space S2 together with the partition wall portion 220.
