The liquid reservoir in the embodiment comprises a shell 1, wherein the shell 1 comprises a cylindrical body 11, the top and the bottom of the cylindrical body 11 are sealed by an upper end cover 12 and a lower end cover 13, so that the inner cavity of the shell 1 forms a closed chamber, and the upper end cover 12 and the lower end cover 13 and the cylindrical body 11 can be fixed in a split mode or arranged integrally, and are arranged in a split mode in fig. 1. The upper and lower directions described in all the embodiments herein are shown in fig. 1 as a perspective view, the height direction of the cylindrical main body 11 is the upper and lower directions, and the state of the liquid reservoir in fig. 1 is also the normal operating state of the liquid reservoir in the present embodiment, that is, the upper end cap 12 and the lower end cap 13 of the liquid reservoir are distributed vertically and upwardly during normal operation.
In addition, the liquid reservoir in the present embodiment further includes an inlet pipe 3 and an outlet pipe 2, the inlet pipe 3 and the outlet pipe 2 are inserted into the inner cavity of the shell 1 from the top of the shell 1, specifically, in fig. 1, namely, the inlet pipe 3 and the outlet pipe 2 are inserted into the upper end cover 12 from the outside of the liquid reservoir, the upper end cover 12 may be provided with a socket 12a, an annular protrusion 121 extending upward is formed at the edge of the socket 12a, the inlet pipe 3 and the outlet pipe 2 may be inserted into the corresponding socket 12a and welded and fixed with the corresponding annular protrusion 121 in contact, the inlet pipe 3 and the outlet pipe 2 are welded with the upper end cover 12 to form an upper end cover 12 assembly, the bottom surface of the lower end cover 13 is welded with the screw 4 to form a lower end cover 13 assembly, and the screw 4 may be used to fix the liquid reservoir.
Refrigerant enters the inner cavity of a liquid receiver from an inlet pipe 3, the liquid receiver is generally arranged between a condenser and a throttling device, the refrigerant condensed by the condenser is mainly liquid refrigerant, and contains a portion of gaseous refrigerant, the liquid refrigerant accumulates at the bottom of the interior of the housing 1, and is thus stored in the interior of the liquid receiver, as shown in fig. 4, which shows the level a of the liquid refrigerant, the gaseous refrigerant entering the housing 1 rises above the liquid refrigerant, when the supply and demand of the system refrigerant reach the balance, the liquid refrigerant is sucked out from the bottom through the outlet pipe 2 to the downstream throttling device, in fig. 4, the lower port of the outlet pipe 2 is arranged close to the bottom of the inner cavity of the shell 1, thus, when the liquid refrigerant accumulates a certain amount, the lower port of the outlet pipe 2 is located below the liquid level a to facilitate the suction of the liquid refrigerant, and the lower port of the outlet pipe 2 may also be defined as a liquid suction port 2 a.
It is to be noted that the refrigerant needs to flow from the inlet tube 3 into the receiver, and the port of the inlet tube 3 located in the receiver body 1 for the refrigerant to flow out is the outlet 3a, and the port of the inlet tube 3 located outside the receiver is the inlet. The outlet 3a of the inlet pipe 3 in the embodiment of the present application faces and is close to the inner wall of the upper portion of the shell 1, and specifically, may face the inner wall of the upper end cover 12 of the shell 1, where "close" means that the outlet 3a and the inner wall have a smaller distance, for example, the distance is not more than 5mm, so that after flowing out from the outlet 3a, the refrigerant can directly impact the corresponding inner wall position, thereby forming a rotating fluid, and obviously, the larger the distance is, the easier the impact is, the more the refrigerant can be ensured to rotate downwards along the inner wall, but the distance cannot be zero, and the premise that the distance is reduced is that the refrigerant can flow out from the distance.
It will be seen that the purpose of being located proximate to the inner wall is to achieve impingement of the refrigerant on the inner wall to form a rotating fluid, and that the spacing between the outlet 3a of the inlet tube 3 and the inner wall of the housing 1 can vary for different size reservoirs or different refrigerant flow rates, but in principle, if the closest location of the inner wall of the housing 1 to the outlet 3 is defined as a first point, then connecting the first point to the outlet 3a and comparing the housing 1 to a second point, then the spacing between the second point and the outlet 3a should be much greater than the spacing between the first point and the outlet 3a by a ratio at least greater than 5: 1.
As shown in fig. 2 and 4, in this embodiment, the end of the inlet pipe 3 inserted into the casing 1 is the inner end, the inner end is bent upward, and the end of the inner end is the outlet 3 a. That is, the inlet pipe 3 has its outlet 3a directed toward and adjacent to the inner wall of the upper end cap 12 by bending its inner end upward.
With such an arrangement, when the refrigerant flows out from the outlet 3a of the inlet pipe 3, the refrigerant can impact the inner wall of the upper end cover 12 above the outlet 3a, so that a centrifugal rotating fluid is formed downwards from the upper end cover 12 and along the inner wall of the cylindrical main body 11, the gas refrigerant is separated through centrifugal and gravity settling, the separation of the gas refrigerant is facilitated, and the flow time of the refrigerant can be effectively prolonged due to the downward flow from the upward rotation, as shown in fig. 4, the refrigerant only has a small amount of bubbles at a position far away from the liquid suction port 2a of the outlet pipe 2, and the potential risk that the outlet pipe 2 brings the gas refrigerant into a system pipeline is small.
In addition, the inlet pipe 3 in this embodiment is bent upward to face and approach the inner wall of the upper portion of the shell 1, and the refrigerant is firstly located at the upper portion of the shell 1 when flowing out, so that the space above the inlet pipe 3 can be fully utilized, the entering refrigerant impacts the inner wall of the upper portion of the shell 1, the rotating fluid formed along the inner wall transits from high flow velocity to low flow velocity, the impact force on the liquid storage surface (namely the liquid surface a of the liquid refrigerant stored at the bottom) can be relieved, compared with the background technology in which the refrigerant enters from the side and flows downward almost directly to generate a larger impact force, the liquid in the inner cavity of the shell 1 in this embodiment is not obviously stirred under the action of the smaller impact, the liquid in the shell 1 tends to be in a steady flow state, the liquid return of the liquid reservoir is stable, and the stability of the system operation can be improved.
Furthermore, the inlet tube 3 is inserted from the top of the reservoir in this application, so that the inlet tube 3 is easy to realize with a shorter design with its outlet 3a facing and close to the inner wall of the upper part of the reservoir; moreover, the inlet pipe 3 and the outlet pipe 2 are inserted from the top of the liquid reservoir, and the inlet pipe 3 and the outlet pipe 2 can be integrally welded, namely, the inlet pipe 3 and the outlet pipe 2 are welded with the shell synchronously, compared with the scheme that the inlet pipe 3 is laterally arranged in the background art, the installation of the embodiment is quicker, and the processing of the shell 1 is simpler.
Referring to fig. 2, in the present embodiment, the inner diameter of the inlet pipe 3 may be about 30% larger than the inner diameter of the outlet pipe 2, that is, the inlet pipe 3 is designed to be thicker, so that the flow passage for the refrigerant to enter the shell 1 is enlarged, the refrigerant guided out from the condenser can quickly enter the interior of the liquid receiver, and the influence on the heat exchange area of the condenser is reduced.
In addition, the angle α of the upward bending of the inner end of the inlet tube 3 in this embodiment may be 20 ° to 35 °, and in fig. 3, since the inner end of the inlet tube 3 is bent upward, the inlet tube 3 actually includes a straight vertical tube section and a bent tube section, where α is an included angle between the bent section of the inlet tube 3 and the vertical direction. Within the above angle range, the refrigerant is ensured to flow upward as much as possible to impact the inner wall of the upper portion of the casing 1, so that the swirling flow starting from the upper portion of the casing 1 downward is formed to extend the flow path, and the angle is also ensured to flow out smoothly after the flow direction is changed, so that a desired swirling flow is formed while maintaining a constant flow velocity. Of course, the bending angle of the inlet pipe 3 may be other than the above-mentioned range of angles.
Fig. 5 is a schematic view of the outlet tube 2 of fig. 2, as shown in fig. 5.
In this embodiment, the inlet pipe 3 and the outlet pipe 2 both include a copper pipe section and a steel pipe section which are connected, specifically, the inlet pipe 3 includes a copper pipe section 31 and a steel pipe section 32, the outlet pipe 2 includes a copper pipe section 21 and a steel pipe section 22, the copper pipes 31 and 21 are located outside the shell 1, and the steel pipe sections 32 and 22 are inserted into the inner cavity of the shell 1. Copper pipe sections 31, 21 are located the outside of casing 1, are convenient for with outside other system's part welded fastening, guarantee welding performance, and steel pipe sections 32, 22 are located casing 1 inner chamber, as long as have certain intensity can, form like this and make up the body and can compromise the performance and practice thrift the cost.
In addition, as shown in fig. 5, the outlet pipe 2 in this embodiment includes a first straight pipe section (composed of the upper portions of the copper pipe section 21 and the steel pipe section 22), a second inclined pipe section 321, and a third straight pipe section 322, which are connected in sequence, the first straight pipe section is inserted into the inner cavity of the casing 1 from the outside of the casing 1, and the end portion of the third straight pipe section 322 is located in the middle of the bottom of the casing 1. Since the inlet pipe 3 and the outlet pipe 2 are both positioned at the top of the liquid receiver, the outlet pipe 2 and the inlet pipe 3 are both eccentrically positioned with respect to the center of the liquid receiver, and the second inclined pipe section 321 is provided here, so that the third straight pipe section 322, which is the lower pipe section of the outlet pipe 2, can be offset to the middle of the shell 1, so that the liquid suction port 2a of the outlet pipe 2 corresponds to the middle of the bottom of the shell 1, and the liquid refrigerant generally collects toward the middle, and the arrangement can ensure that the liquid suction port 2a of the outlet pipe 2 can suck the liquid refrigerant at any time. In fig. 4 and 5, the liquid suction port 2a of the outlet pipe 2 is designed as a chamfered port to facilitate introduction of the liquid refrigerant.
Example 2
Referring to fig. 6-8, fig. 6 is a schematic view of a receiver according to a second embodiment of the present application, also illustrating a refrigerant flow path in dashed lines; FIG. 7 is a schematic view of the inlet tube 3 of FIG. 6; fig. 8 is a front view of fig. 7, illustrating the angle β at which the platen 3b is tilted.
This embodiment is different from the first embodiment in the way in which the inlet pipe 3 is formed next to the inner wall of the upper portion of the housing 1. As shown in fig. 6, the pipe section of the inlet pipe 3 inserted into the housing 1 is a straight pipe section, and the side wall of the straight pipe section is provided with an opening which forms the outlet 3a of the inlet pipe 3. The side wall of the inlet pipe 3 is provided with the opening as the outlet 3a, the outlet 3a is not just opposite to the refrigerant flowing out from the lower part, the refrigerant flows out from the side surface of the inlet pipe 3, and the outlet 3a is also close to the inner wall of the upper part of the shell 1, so that the same purpose as the first embodiment can be achieved, namely the potential risk of bringing the gaseous refrigerant into a system pipeline by the outlet pipe 2 is low, the impact on the liquid level a is small, no obvious stirring is caused, the liquid in the shell 1 tends to be in a steady flow state, the liquid return of the liquid reservoir is stable, and the stability of the operation of the system can be improved.
Specifically, as shown in fig. 6, the inlet pipe 3 is open at both ends, and a pressing plate 3b is further provided, one end of the pressing plate 3b is connected to the bottom wall of the opening, and the pressing plate 3b seals the lumen of the inlet pipe 3, wherein sealing means completely sealing or substantially sealing, that is, the refrigerant or most of the refrigerant entering the inlet pipe 3 cannot flow downward along the axial direction of the inlet pipe 3. Thus, after entering the inlet tube 3, the refrigerant reaches the position of the pressure plate 3b, and due to the blockage of the pressure plate 3b, the refrigerant cannot continue to flow downward and flows out from the lower end port of the inlet tube 3, and only flows out from the opening (i.e., the outlet 3a) formed in the side surface of the inlet tube 3 along the pressure plate 3 b.
Specifically, the pressing plate 3b is disposed obliquely with respect to the up-down direction, as shown in fig. 8, and has an inclination angle β, where the inclination angle β is an included angle between the plate surface of the pressing plate 3b and the vertical direction, so that the refrigerant enters along the axial direction of the inlet pipe 3 and flows obliquely to the open hole position, and the refrigerant flows obliquely downward, so that the direction of the refrigerant changes more smoothly, and the refrigerant can flow out of the inlet pipe 3 at a certain speed and enter the inner cavity of the liquid receiver. Beta may range from 25 deg. -35 deg. to achieve a smooth drainage.
When in processing, one side of the inlet pipe 3 can directly push part of the pipe wall of the inlet pipe 3 to the inner cavity of the inlet pipe 3 by cutting, extruding and the like, the bottom of the part of the pipe wall and the pipe wall of the inlet pipe 3 are kept as a whole, the other part is separated from the tube wall of the inlet tube 3, after entering the inner cavity of the inlet tube 3, the periphery of the tube wall of the part can be contacted with the inner surface of the tube cavity to seal the tube cavity, the orthographic projection of the part of the tube wall in the axial direction of the inlet tube 3 coincides with the cross section of the lumen, or the part of the tube wall does not completely seal the lumen based on the tube wall form limitation, the orthographic projection of the tube cavity can be basically coincident with the cross section of the tube cavity (as long as most of refrigerant is guided to flow out from the position of the side opening), so that the part of the tube wall can automatically form a pressure plate 3b, at the moment, the pressure plate 3b and the inlet tube 3 are of an integrated structure, this formation is easy to realize and the pressure plate 3b and the inlet tube 3 maintain a stable connection relationship. Of course, the pressure plate 3b may be provided separately from the inlet tube 3. It will be appreciated that this can be achieved in other ways than by providing the pressure plate 3b such that the openings provided in the side wall form the outlet 3a, for example the ports at the lower end of the inlet tube 3 can be closed, but obviously the arrangement of the pressure plate 3b is easy to machine and also facilitates the formation of an inclined transition path to engage the lumen and openings of the inlet tube 3.
Furthermore, as will be understood from a comparison of fig. 2 and 6, in the first embodiment, the inlet pipe 3 is bent to form the outlet 3a adjacent to the inner wall of the upper portion of the reservoir, and the inlet pipe 3 is formed to have a certain length, and the combined arrangement of the copper pipe section 31 and the steel pipe section 32 is performed for cost saving. And in the second embodiment, import pipe 3 directly forms export 3a from the side opening, export 3a need press close to the inner wall on cistern upper portion, then import pipe 3 stretches into casing 1's length shorter, import pipe 3 only need stretch into casing 1 a segment can to guarantee that the opening position of its side is in the upper portion of cistern, at this moment, import pipe 3 can directly be shorter copper pipe, need not to carry out the integrated design with the steel pipe, import pipe 3 structure that forms like this is more simple, the cost also can remain relatively lower.
It should be noted that in the embodiment of the present application, the outlet 3a of the inlet pipe 3 is close to the inner wall of the upper part of the shell 1, so that the refrigerant flowing out through the outlet 3a can directly impact the inner wall of the upper part of the shell 1, thereby easily forming a rotating fluid from the upper part downwards to obtain a longer flow path, thereby reducing the direct downward impact as much as possible, and for this purpose, the outlet 3a of the inlet pipe 3 in the above two embodiments is close to the inner wall of the upper end cover 12 or the vicinity of the upper end cover 12, and the outlet 3a is arranged close to the inner wall of the upper end cover 12 (specifically, the side wall of the upper end cover 12) so that the outlet 3a is as close to the top wall of the inner cavity of the shell 1 as possible, but it should be understood that the outlet 3a is close to the inner wall of the upper part of the shell 1, and is not necessarily close to the inner wall of the upper end cover 12 or the vicinity of the upper end cover 12.
Furthermore, it should be emphasized that the upper part of the present application may be a part from the top to the bottom of the housing 1/3, and the closer the outlet 3a is to the height of the top wall of the housing 1 in the height direction, the longer the path of the swirling flow, the more favorable the gas-liquid separation, the more favorable the reduction of the impact on the liquid storage surface and the generation of bubbles.
The principles and embodiments of the present application are explained herein using specific examples, which are provided only to help understand the method and the core idea of the present application. It should be noted that, for those skilled in the art, it is possible to make several improvements and modifications to the present application without departing from the principle of the present application, and such improvements and modifications also fall within the scope of the claims of the present application.
