[0022] The present application will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, those skilled in the art will understand that these drawings are drawn only for the purpose of explaining the preferred embodiments and therefore should not be construed as limiting the scope of the present application. Furthermore, unless specifically indicated, the drawings are intended only to conceptually represent the composition or structure of the described objects and may contain exaggerated representations, and the drawings are not necessarily drawn to scale.

[0024] Figure 2 yes Figure 1 Another perspective view of the embodiment shown.

[0025] Figure 3 This is a cross-sectional view of an embodiment of the evaporator according to this application. Detailed Implementation

[0026] Preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of this application.

[0027] First, it should be noted that the directional terms such as top, bottom, upward, and downward mentioned in this article are defined relative to the directions shown in the various accompanying figures. These are relative concepts and therefore can vary depending on the location and usage of the feature. Therefore, these directional terms should not be construed as restrictive.

[0028] Furthermore, it should be noted that any single technical feature described or implied in the embodiments herein, or any single technical feature shown or implied in the accompanying drawings, can still be combined among these technical features (or their equivalents) to obtain other embodiments of this application not directly mentioned herein.

[0029] It should be noted that in different figures, the same reference numerals denote the same or substantially the same components.

[0030] This application provides a baffle assembly that can be disposed at the outlet of an evaporator in an air conditioning system and is positioned in the flow path of a gas-liquid mixture leaving the evaporator. In one embodiment, at least a portion of the gas-liquid mixture must flow through an embodiment of the baffle assembly according to this application before leaving the evaporator.

[0031] In one embodiment, the baffle assembly according to this application includes: a body, two or more first connecting portions attached to the periphery of the body, and two or more second connecting portions attached to the periphery of the body. The first and second connecting portions are respectively provided with a plurality of first through holes and a plurality of second through holes. It is readily understood that due to the presence of the first and second through holes, the first and second connecting portions will each have a hole distribution density. The hole distribution density can be calculated, for example, by dividing the cross-sectional area of ​​all through holes on each connecting portion by the cross-sectional area of ​​the connecting portion itself. In one embodiment, the first connecting portion has a first hole distribution density, and the second connecting portion has a second hole distribution density. In one embodiment, the first hole distribution density and the second hole distribution density are not equal.

[0032] Each of the first connecting parts can be arranged such that the flow path of fluid passing through one of the first connecting parts is spatially spaced from the flow path of fluid passing through the other of the first connecting parts. That is, the flow paths of fluid passing through each of the first connecting parts do not intersect each other for at least a certain distance after the fluid passes through each of the first connecting parts. The flow paths of the fluid will be described in more detail below.

[0033] Figure 1 This is a perspective view of one embodiment of the baffle assembly according to this application, and Figure 2 yes Figure 1 Another perspective view of the illustrated embodiment. As shown, the baffle assembly 100 includes a body 110 extending along a first axis A1. The body 110 may be configured to have a generally rectangular outline and extends from a first edge 101 to a second edge 102 opposite to the first edge 101. Furthermore, the body 110 extends from a first end 101a to a second end 102a. The rectangular outline of the body 110 is also axisymmetric about a second axis A2. And the first axis A1 and the second axis A2 intersect at point O.

[0034] In the illustrated embodiment, the body 110 may consist of two plate-shaped structures. In another embodiment, the body may also consist of a single plate, such as a single flat plate. As shown, the two plate-shaped structures are attached together on one side and form a first predetermined angle relative to each other. For example, the first predetermined angle may be between 90 and 170 degrees. In one embodiment, the shape of the body 110 is adapted to guide liquid collected on the surface of the body 110 to flow along the body 110 and eventually exit the baffle assembly at a first end 101a or a second end 102a. In the illustrated embodiment, the body 110 may have at least one bend in cross-section. In embodiments where the body consists of a single plate, the body may be constructed to have a generally rectangular cross-section.

[0035] The first connecting portion 120 and the second connecting portion 130 may be attached to the body 110 at the first edge 101 and the second edge 102. In the illustrated embodiment, one of the first connecting portions 120 is attached to the first edge 101 of the body 110 at a first end 101a adjacent to the body 110, and the other of the first connecting portions 120 is attached to the second edge 102 of the body 110 at a second end 102a adjacent to the body 110; one of the second connecting portions 130 is attached to the first edge 101 of the body 110 at a second end 102a adjacent to the body 110, and the other of the second connecting portions 130 is attached to the second edge 102 of the body 110 at a first end 101a adjacent to the body 110. However, the positions of the respective first connecting portions 120 and second connecting portions 130 are not necessarily located adjacent to the first end 101a or the second end 102a, and may be spaced apart from the first end 101a or the second end 102a. Each of the first connecting portions 120 and each of the second connecting portions 130 may also form a second predetermined angle with the body 110, for example, between 90 degrees and 170 degrees. In one embodiment, the first connecting portions 120 and 130 attached to the first edge 101 of the body 110 and the first connecting portions 120 and 130 attached to the second edge 102 of the body 110 form a symmetrical structure about the intersection point O of the first axis A1 and the second axis A2.

[0036] Each first connecting portion 120 may include a plurality of first through holes, and the first through holes are configured to be substantially parallel to each other. The first through holes may be spaced apart from each other according to a first distance. Therefore, the first connecting portion has a first hole distribution density. As shown, the working fluid passing through the first connecting portion 120 flows along... Figure 1 and Figure 2 Movement in the directions indicated by arrows B1 and B2 forms a flow path for the first connecting portion 120. As shown, the working fluid passing through the first connecting portion 120 attached to the first edge 101 of the body 110 and the working flow passing through the first connecting portion 120 attached to the second edge 102 of the body 110 have their flow paths within the baffle assembly 100 spaced apart from each other. Specifically, as... Figure 2 As shown, the working fluids moving in the direction of arrow B1 and in the direction of arrow B2 are symmetrically distributed about the geometric center of the body 110 (or the intersection O of the first axis A1 and the second axis A2), and will cause the aforementioned working fluids to tend to move in a counterclockwise direction as shown by arrow B3. In another embodiment, the positions of the first and second connecting portions on the respective edges of the body are reversed compared to the illustrated embodiment, which will... Figure 2From the perspective shown, the working fluid tends to move in a clockwise direction. It is easy to understand that the clockwise or counterclockwise movement of the working fluid is roughly centered on the geometric center. In other words, the working fluid is roughly geometrically symmetrically distributed about the geometric center of the body 110's contour.

[0037] Each second connecting portion 130 may also include a plurality of second through holes, each second through hole being configured to be substantially parallel to each other. As shown, each second through hole may be spaced apart from each other by a second distance, and the second distance is greater than a first distance. Therefore, the second connecting portion has a second hole distribution density. In the illustrated embodiment, the first hole distribution density is greater than the second hole distribution density. In another embodiment, the first hole distribution density may be set to be less than the second hole distribution density, and a similar effect can still be obtained. Therefore, the working fluid passing through each of the second connecting portions 130 does not impede the flow of working fluid passing through the first connecting portion opposite to the second connecting portion 130, and assists in generating the counterclockwise or clockwise movement described above.

[0038] exist Figure 1 and Figure 2 In the illustrated embodiment, the cross-sectional dimensions of the first through hole and the second through hole are configured to be approximately equal. However, the cross-sectional dimensions of the first through hole and the second through hole may also be configured to be different, or they may be arranged in a different pattern than those shown in the illustration. The first through hole and the second through hole may have a cross-section of one of the following shapes: circular, elliptical, triangular, prismatic, rectangular, trapezoidal, etc.

[0039] In the illustrated embodiment, the body 110 has a generally rectangular outline. However, the body 110 may also adopt other geometric shapes with a geometric center as its outline. For example, the outline of the body 110 may be constructed to have one of the following shapes: rectangle, rhombus, circle, or ellipse.

[0040] In one embodiment, the body may have a first edge and a second edge opposite to the first edge, with a first connecting portion and a second connecting portion alternately attached to the first edge of the body, and the first connecting portion and the second connecting portion alternately attached to the second edge of the body, such that the first connecting portion attached to the first edge of the body is opposite to the second connecting portion attached to the second edge of the body, and the second connecting portion attached to the first edge of the body is opposite to the first connecting portion attached to the second edge of the body. This embodiment still achieves the flow path or flow channel arrangement of the working fluid described above, and provides staggered flow paths on the body so that the working fluid is symmetrically distributed about the geometric center of the body and undergoes approximately rotational motion.

[0041] Figure 3This is a cross-sectional view of one embodiment of the evaporator according to this application. The evaporator 10 has a housing 11 and an opening 12. In the illustrated embodiment, the opening 12 is located at the top of the housing 11. The baffle assembly 100 according to this application is configured on the inner wall of the housing 11 adjacent to the opening 12, such that the baffle assembly 100 is positioned on a flow path from a cavity defined inside the housing 11 to the opening 12. More specifically, the body 110 of the baffle assembly 100 is configured to face the opening 12, and respective first connecting portions 120 and second connecting portions 130 are configured to be attached between the inner wall of the housing 11 and the body 110.

[0042] In use, the gas-liquid mixture generated from the working fluid within the evaporator 11 passes through the respective first connecting portions 120 and second connecting portions 130 in the directions indicated by arrows C1 and C2, and forms, for example, above the body 110. Figure 2 The counter-clockwise motion is indicated by arrow B3. During this counter-clockwise motion, centrifugal force will cause at least a portion of the liquid in the gas-liquid mixture to aggregate and be collected. Some liquid will condense into droplets and collect on the upper surface of the body 110, eventually exiting the baffle assembly from the first end 101a or the second end 102a of the body 110 and dripping back into the lower part of the evaporator 11. The remaining working fluid... Figure 3 It exits the evaporator through opening 12 in the direction indicated by the middle arrow C3, and is selectively supplied to downstream compressors or other components.

[0043] This application also relates to an air conditioning system that includes the baffle assembly described above, or includes the evaporator described above.

[0044] The baffle assembly, evaporator, and air conditioning system of this application have the advantages of simple structure, convenient installation, and reliable use, which improves the gas-liquid separation capability and thus improves the cooling capacity of the air conditioning system.
