Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a flow path integration module for an air conditioning system and an air conditioning system. Background Technology

[0002] Currently, in the integrated design of air conditioning system piping, flow path modules are set up to achieve miniaturized design of the air conditioning refrigerant flow path.

[0003] In related technologies, flow path modules typically consist of a flow channel plate structure with flow channels and a flat plate structure for sealing the flow channel plate. The flat plate structure is located on the open side of the flow channel plate structure and is connected to the end face of the flow channel plate structure on the open side. When the refrigerant flows within the flow path module, the flat plate structure will be subjected to refrigerant pressure, and the pressure on the flat plate structure at all locations will be vertically downward (i.e., on the side away from the flow channel plate structure). This results in a high total pressure on the flat plate structure, creating a risk of cracking at the connection between the flat plate structure and the flow channel plate structure.

[0027] In the description of this application, "multiple" means two or more.

[0028] In the description of this application, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or it may include the first and second features not being in direct contact but being in contact through another feature between them.

[0030] The following is for reference. Figures 1-19 The present application describes a flow path integration module 100 for an air conditioning system. The flow path integration module 100 is applied to the air conditioning system and can realize the miniaturized design of the air conditioning refrigerant flow path for the working fluid (i.e., refrigerant) to flow through.

[0031] According to an embodiment of this application, a flow path integration module 100 for an air conditioning system includes a flow channel plate body 1 and a flow channel plate 2.

[0032] The flow channel plate body 1 has a first flow channel portion 11 that is open to a first side in a first direction, and the flow channel plate body 1 is provided with an interface 12 that communicates with the first flow channel portion 11. The interface 12 can be connected and cooperated with a pipe structure to connect the flow path integration module 100 to the air conditioning system. The working fluid in the air conditioning system can flow into the first flow channel portion 11 through the interface 12, and the interface 12 can also be used to discharge the working fluid in the first flow channel portion 11 out of the flow channel plate body 1.

[0033] Furthermore, the flow channel plate 2 has a second flow channel portion 21 that is open to a second side in the first direction. The flow channel plate 2 is connected to the flow channel plate body 1, and the first flow channel portion 11 and the second flow channel portion 21 are connected and together form a working fluid flow channel for the flow of working fluid. The flow path angle of the working fluid flow channel changes at the connection and engagement point of the first flow channel portion 11 and the second flow channel portion 21, and the connection point of the first flow channel portion 11 and the second flow channel portion 21 is smoothly transitioned.

[0034] It should be noted that in the first direction, the first side is opposite to the second side, so that the open sides of the first flow channel 11 and the second flow channel 21 are arranged opposite to each other. The flow channel plate body 1 and the flow channel plate 2 can cooperate along the first direction and together form the working fluid flow channel through the first flow channel 11 and the second flow channel 21.

[0035] It is understood that the first flow channel section 11 is a flow channel structure formed on the flow channel plate body 1 and open to the first side, and the second flow channel section 21 is a flow channel structure formed on the flow channel plate 2 and open to the second side. The first flow channel section 11 and the second flow channel section 21 are connected and together constitute the working fluid flow channel, so as to form a working fluid flow channel for the working fluid to flow through the cooperation of the flow channel plate body 1 and the flow channel plate 2.

[0036] Reference Figure 3 As shown, the first flow channel 11 and the second flow channel 21 are connected and fitted together, and the flow direction of the working fluid changes when it flows through the connection point of the first flow channel 11 and the second flow channel 21. That is, the flow direction of the working fluid changes when it flows from the first flow channel 11 to the second flow channel 21 and from the second flow channel 21 to the first flow channel 11. Since the first flow channel 11 and the second flow channel 21 have a smooth transition at the connection point, excessive impact force of the working fluid on the flow channel plate 2 can be avoided, which could lead to local stress concentration in the flow path integrated module 100.

[0037] Combination Figure 3 and Figure 16 As shown, after the working medium flows into the second flow channel 21 from the first flow channel 11, the working medium can flow in the second flow channel 21 along the extension direction of the second flow channel 21, and the guiding direction of the second flow channel 21 for the working medium can be set perpendicular to the first direction.

[0038] The flow channel plate body 1 is provided with an interface 12, through which the working fluid flows into the working fluid channel. After the working fluid flows into the working fluid channel, the pressure generated by the working fluid on one side of the flow channel plate 2 will act on the area where the flow channel plate 2 forms the second flow channel portion 21. Since the second flow channel portion 21 is open to the second side, it can play a certain role in buffering the impact force and pressure, thereby reducing the risk of cracking at the connection between the flow channel plate 2 and the flow channel plate body 1, and ensuring the reliability of the connection between the flow channel plate 2 and the flow channel plate body 1.

[0039] Currently, in the integrated design of air conditioning system piping, flow path modules are used to achieve miniaturized refrigerant flow paths. In related technologies, a flow path module typically consists of a flow channel plate structure with flow channels and a flat plate structure for sealing the flow channel plate. The flat plate structure is located on the open side of the flow channel plate structure and connects to the end face of the flow channel plate structure on the open side. When the refrigerant flows within the flow path module, the flat plate structure is subjected to refrigerant pressure, and the pressure on the flat plate structure at all locations is vertically downward (i.e., the side away from the flow channel plate structure). This results in a high total pressure on the flat plate structure, creating a risk of cracking at the connection between the flat plate structure and the flow channel plate structure.

[0040] According to the embodiment of this application, the flow path integration module 100 for an air conditioning system has a first flow path portion 11 formed on the flow path plate body 1, which is open to a first side, and a second flow path portion 21 formed on the flow path plate 2, which is open to a second side. The first flow path portion 11 and the second flow path portion 21 together constitute the working fluid flow path. The second flow path portion 21 is used to withstand the pressure generated by the flow of the working fluid. By setting the second flow path portion 21, the pressure can be avoided from acting directly on the plane opposite to the flow path plate 2 and the flow path plate body 1, reducing the risk of separation between the flow path plate 2 and the flow path plate body 1 (e.g., cracking at the connection and mating point of the flow path plate 2 and the flow path plate body 1), so as to ensure the reliability of the working fluid flow path and prevent the working fluid from leaking at the flow path integration module 100.

[0041] It should be noted that in the flow path integration module 100, multiple sets of first flow path sections 11 can be provided on the flow path plate body 1, and multiple sets of second flow path sections 21 can be provided on the flow path plate 2.

[0042] In some embodiments, multiple sets of first flow channel sections 11 can be respectively configured in a one-to-one correspondence with multiple sets of second flow channel sections 21; in other embodiments, a portion of the multiple sets of first flow channel sections 11 are respectively configured in a one-to-one correspondence with multiple sets of second flow channel sections 21, while another portion of the multiple sets of first flow channel sections 11 can be directly configured to correspond with the hole structure formed on the flat plate flow channel 2. Furthermore, the structure of each set of first flow channel sections 11 can be different; similarly, the structure of each set of second flow channel sections 21 can be different, as long as the second flow channel section 21 matches the first flow channel section 11.

[0043] Reference Figure 3 and Figure 15 As shown, the second flow channel 21 has a first guide surface 22. The first guide surface 22 is disposed opposite to the first flow channel 11 in a first direction, and at least a portion of the first guide surface 22 is disposed opposite to the interface 12 in the first direction. The first guide surface 22 is used to guide the working fluid flowing from the interface 12 to the first guide surface 22, so as to guide the working fluid to a position downstream of the first guide surface 22 in the working fluid flow channel (i.e., the downstream side of the working fluid flow path), or to guide the working fluid flowing through the first guide surface 22 to the interface 12 side, thereby guiding the working fluid to the interface 12 so that the working fluid can flow out of the working fluid flow channel.

[0044] In the flow path integration module 100, the working fluid can flow into the first flow channel section 11 through the interface 12. Since the interface 12 is arranged opposite to at least part of the first guide surface 22, the first guide surface 22 can guide the working fluid flowing from the interface 12 to the first guide surface 22, so as to assist the working fluid in the working fluid flow channel and help reduce the resistance encountered by the working fluid in the working fluid flow channel.

[0045] The working fluid can flow to the first guide surface 22 in the working fluid channel, and the working fluid is guided to the interface 12 through the first guide surface 22, so that the working fluid can flow out of the working fluid channel from the interface 12.

[0046] It is understandable that the way the first guide surface 22 guides the working fluid is related to the flow direction of the working fluid in the working fluid channel.

[0047] Combination Figure 3 and Figure 10 As shown, in some embodiments of this application, the first guide surface 22 is constructed as an arc-shaped surface, and the arc-shaped opening of the arc-shaped surface faces the working fluid flow channel side, so that the first guide surface 22 has a good guiding effect on the flow direction of the working fluid.

[0048] It is understandable that the curved surface is used to guide the flow direction of the working fluid in the working fluid channel, and during the process of the curved surface and the working fluid cooperating, the flow resistance of the working fluid at the curved surface is small, thereby reducing the flow resistance of the working fluid in the channel and reducing the energy consumption of the air conditioning system.

[0049] It should be noted that the first guide surface 22 is the wall surface in the flow channel plate 2 used to enclose and form the second flow channel portion 21, and at least part of the wall surface enclosing the second guide portion is constructed as the first guide surface 22, so as to reduce the flow resistance of the working fluid in the working fluid flow channel through the first guide surface 22. Of course, the second flow channel portion 21 in the flow channel plate 2 can be entirely enclosed and formed by the first guide surface 22, so that the flow resistance of the working fluid flowing through the second flow channel portion 21 is small. For example, the first guide surface 22 is constructed as a hemispherical arc surface, etc. In the flow channel plate 2, the wall surface enclosing and forming the second flow channel portion 21 can be formed by a combination of arc surface and planar structure. For example, by setting the arc surface around the circumferential direction of the planar surface, the edge of the arc surface is correspondingly set with the inner peripheral wall of the flow channel plate body 1 to prevent sharp corners from being generated in the transition area between the flow channel plate body 1 and the flow channel plate 2.

[0050] Combination Figure 12 and Figure 15 As shown, in some other embodiments of this application, the first guiding surface 22 is constructed as a guiding slope, and the angle between the plane where the guiding slope is located and the first direction is set to an obtuse angle, so that the guiding slope has a guiding effect on the flow direction of the working medium, so as to prevent the formation of a "dead water zone" in the working medium flow channel and help improve the flow effect of the working medium in the working medium flow channel.

[0051] In existing technologies, flow path modules typically consist of a flow channel plate structure with flow channels and a flat plate structure for sealing the flow channel plate. The flat plate structure is located on the open side of the flow channel plate structure, resulting in a 90° sharp angle at the mating point of the flow channel formed by the flow channel plate structure and the flat plate structure. This forces the flow direction of the working fluid to change by 90° after entering the flow channel, leading to high flow resistance in the flow channel. Furthermore, eddies are easily generated in the 90° corner region where the flow channel plate interface 12 transitions perpendicularly to the flat plate structure, affecting the flow efficiency of the working fluid in the flow channel. Additionally, impurities are accommodated and deposited in this area, blocking the flow channel.

[0052] In this application, the first guide surface 22 and the first flow channel 11 are disposed opposite each other in a first direction, so that the first guide surface 22 can guide the working fluid flowing from the first flow channel 11 to the second flow channel 21, and can avoid the formation of a 90° corner area in the working fluid flow channel, avoid the formation of a "dead water zone" in the corner area, ensure the flow effect of the working fluid in the working fluid flow channel, and also prevent impurities from depositing in the corners of the working fluid flow channel. Here, the "dead water zone" refers to the area where the working fluid flow rate is slow.

[0053] In some embodiments of this application, the wall surface of the flow channel plate body 1 that encloses the first flow channel portion 11 (i.e., the inner peripheral wall of the flow channel plate body 1) and the first guide surface 22 are smoothly transitioned, thereby reducing the flow resistance in the area where the first flow channel portion 11 and the second flow channel portion 21 meet, making the working fluid flow smoothly in the working fluid flow channel, which helps to reduce the energy consumption required to drive the flow of the working fluid in the air conditioning system.

[0054] It is understandable that by avoiding a smooth transition between the enclosed first flow channel 11 and the first guide surface 22, the resistance of the working fluid flowing from the first flow channel 11 into the second flow channel 21 can be reduced, which helps to improve the flow effect of the working fluid in the working fluid flow channel.

[0055] Reference Figure 3 As shown, in some embodiments of this application, the flow channel plate body 1 includes a first guide wall 131 and a second guide wall 132. The first guide wall 131 extends along a first direction, and a first flow channel segment 111 of a first flow channel portion 11 is formed at the first guide wall 131, extending along the first direction. The second guide wall 132 extends along a second direction, and a second flow channel segment 112 of the first flow channel portion 11 is formed at the second guide wall 132, communicating with the first flow channel segment 111, and the second flow channel portion 21 extends along the second direction. The first direction and the second direction intersect.

[0056] Reference Figure 3 The second flow channel 21 is disposed opposite to the first flow channel 11 in the first direction, and the second flow channel 21 is disposed corresponding to the first flow channel segment 111 and the second flow channel segment 112 in the extension direction, so as to increase the cross-sectional size of the working medium flow channel for the working medium to flow through the second flow channel 21, thereby ensuring the working medium flow effect in the flow path integrated module 100.

[0057] It should be noted that in the main body of the flow channel plate 1, a first flow channel section 111 extending in the first direction is formed by the first guide wall 131, and an interface 12 is formed at the end of the first guide wall 131 away from the flow channel plate 2, so that the pipe 3 can be arranged on the main body of the flow channel plate in the first direction, and the working fluid can flow through the first flow channel section 111 in the first direction.

[0058] Furthermore, the second guide wall 132 is connected to the first guide wall 131 and extends in the second direction to form a second flow channel section 112 that communicates with the first flow channel section 111 and extends in the second direction. The flow path of the working medium is adjusted by the cooperation of the first flow channel section 111 and the second flow channel section 112, so that the working medium can be guided to another interface 12.

[0059] Reference Figure 3 As shown, the first flow channel section 11 includes two first flow channel sections 111 and a second flow channel section 112 connecting the two first flow channel sections 111.

[0060] In some embodiments of this application, the flow channel plate body 1 is provided with a second flow guide surface 14 at the connection between the first flow guide wall 131 and the second flow guide wall 132. In the first direction, the flow cross-sectional area of ​​the flow channel segment corresponding to the second flow guide surface 14 in the first flow channel segment 111 is arranged to increase towards the first side of the first direction, thereby reducing the flow resistance of the working medium from the first flow channel segment 111 to the second flow channel segment 112 and ensuring the flow effect of the working medium in the working medium flow channel.

[0061] Understandably, the second guide surface 14 can guide the flow of the working fluid in the first flow channel section 11.

[0062] like Figure 3 As shown, in a further embodiment of this application, the second guide surface 14 is constructed as an arc-shaped guide surface, and the arc-shaped opening of the arc-shaped guide surface faces the side away from the working fluid flow channel, so that the arc-shaped guide surface can guide the working fluid flowing from the first flow channel section 111 to the second flow channel section 112, and reduce the resistance of the working fluid flowing from the first flow channel section 111 to the second flow channel section 112, thereby ensuring the flow effect of the working fluid in the working fluid flow channel.

[0063] It is understandable that if the angle between the first guide wall 131 and the second guide wall 132 is small (e.g., a right angle or an acute angle), the working fluid in the first flow channel section 111 will need to pass through a large bend before it can flow into the second flow channel section 112. In this application, by setting an arc-shaped guide surface, the transition between the first guide wall 131 and the second guide wall 132 can be smooth, thereby reducing the flow resistance of the working fluid and helping to improve the flow effect of the working fluid in the first flow channel section 11.

[0064] like Figure 3 As shown, in some embodiments of this application, the flow channel plate 2 is provided with a raised portion 23, which is raised from the flow channel plate 2 toward the first side, and a second flow channel portion 21 is formed on the side of the raised portion 23 opposite to the flow channel plate body 1, which is recessed from the surface of the flow channel plate 2 opposite to the flow channel plate body 1 toward the first side.

[0065] It is understandable that by providing a protrusion 23 on the flow channel plate 2, a second flow channel portion 21 that is recessed towards the first side can be formed on the flow channel plate 2, and the overall thickness of the flow channel plate 2 is reduced. When the thickness of the flow channel plate 2 is reduced, the weight of the flow channel plate 2 can be reduced while meeting the strength requirements of the flow channel plate 2, thereby achieving a lightweight design of the flow channel plate 2.

[0066] Reference Figure 3 As shown, by forming a raised portion 23 on the flow channel plate 2 and forming a groove structure in the opposite direction of the raised portion 23, the second flow channel portion 21 described above is formed by enclosing the groove structure, thereby achieving a design where the thickness of each region of the flow channel plate 2 is relatively uniform.

[0067] The raised portion 23 can be formed on the flow channel plate 2 by a stamping process to achieve an integrated design of the flow channel plate 2.

[0068] like Figure 12 As shown, in some other embodiments of this application, the flow channel plate 2 is provided with a boss 24 protruding towards the second side, the boss 24 forming a second flow channel portion 21, and the second flow channel portion 21 is recessed from the boss 24 towards the first side.

[0069] It is understandable that a boss 24 is provided on the second side of the flow channel plate 2. The boss 24 can increase the local thickness of the flow channel plate 2, so that a second flow channel portion 21 recessed towards the first side can be provided in the area with a larger thickness in the flow channel plate 2 (i.e., at the location of the boss 24). Thus, when the main body thickness of the flow channel plate 2 is uniform, it is not necessary to occupy the space of the flow channel plate 2 on the first side, that is, it is not necessary to provide the aforementioned raised portion 23, so that the surface of the flow channel plate 2 on the first side is flat. The flow path integration module 100 is constructed into a relatively flat structure on the surface of the first side, which helps to reduce the difficulty of installing and fixing the flow plate in the air conditioning system.

[0070] In a further embodiment of this application, the flow channel plate body 1 is sleeved on the boss 24 and is arranged around the boss 24 in the circumferential direction. The inner circumferential wall of the flow channel plate body 1 is fitted with the outer circumferential wall of the boss 24, so that the flow channel plate body 1 and the boss 24 fit tightly, preventing the formation of gaps between the flow channel plate body 1 and the outer circumferential side of the boss 24, thereby ensuring the reliability of the flow channel body 1 and the flow channel plate 2 forming the working fluid flow channel.

[0071] It is understandable that during the connection and engagement process between the flow channel plate body 1 and the flow channel plate 2, the boss 24 extends into the flow channel plate body 1 from the open end of the first flow channel part 11, and the outer peripheral wall of the boss 24 is fitted with the inner wall surface of the flow channel plate. Moreover, the end of the flow channel plate body 1 can abut against the surface of the flow channel plate 2 on the second side, thereby enabling the positioning and engagement of the flow channel plate body 1 and the flow channel plate 2 in multiple directions. This can save the positioning fixtures required during the welding process of the flow channel plate body 1 and the flow channel plate 2, and reduce the difficulty of connecting and fixing the flow channel plate body 1 and the flow channel plate 2.

[0072] In some embodiments of this application, the flow channel plate body 1 and the flow channel plate 2 are welded together. The welded connection has high reliability, ensuring the connection reliability between the flow channel plate body 1 and the flow channel plate 2. Furthermore, the gap between the flow channel plate body 1 and the flow channel plate 2 can be filled with solder to improve the sealing performance of the working fluid flow channel. The welding method may include, but is not limited to, brazing.

[0073] In some embodiments of this application, the flow channel plate body 1 also includes a pipe 3, which is installed and cooperates with the interface 12, so that the flow path integration module 100 can be connected and cooperated with other devices (such as solenoid valves, expansion valves and other valve structures) through the pipe 3.

[0074] Reference Figure 3 As shown, a step portion 15 is formed on the first guide wall 131. The step portion 15 is adapted to limit the insertion depth of the pipe 3 when it is inserted and mated with the interface 12, so as to improve the mating reliability of the pipe 3 and the flow channel plate body 1.

[0075] Combination Figure 8 and Figure 9 As shown, in some embodiments of this application, the flow channel plate body 1 is provided with a plurality of interfaces 12, each interface 12 can be used to connect and cooperate with the piping 3, and each first flow channel part 11 is connected and cooperated with at least one interface 12.

[0076] In a further embodiment of this application, at least one of the plurality of interfaces 12 is arranged in a communication direction parallel to the first direction, so that the pipe 3 can be installed and fitted with the interface 12 along the first direction, so that the interface 12 is exposed on the side away from the flow channel plate 2, thereby arranging the interface 12 in the flow channel plate body 1 at a position that is convenient for connection and fitting with the pipe 3.

[0077] In some embodiments of this application, at least one of the multiple interfaces 12 is arranged with its communication direction perpendicular to the first direction, thereby setting the communication direction of the interface 12 parallel to the arrangement of the flow channel plate 2, so that the pipe 3 can be installed and fitted with the interface 12 along the direction perpendicular to the first direction, so that the interface 12 is exposed in the lateral direction, thereby arranging the interface 12 in the flow channel plate body 1 at a position that is convenient for connection and fit with the pipe 3.

[0078] Among them, "the connection direction of interface 12" refers to the installation and mating direction of interface 12 and piping 3.

[0079] The flow path integration module 100 according to the embodiments of this application has at least the following advantages compared with the prior art: (1) In the flow path integration module 100, the first flow channel part 11 in the flow channel plate body 1 and the second flow channel part 21 in the flow channel plate 2 together enclose and define the working fluid flow channel. The second flow channel part 21 is used to bear the pressure generated by the flow of the working fluid, so as to avoid the pressure acting directly on the side plane of the flow channel plate 2 and the flow channel plate body 1 opposite to each other, thereby reducing the risk of separation between the flow channel plate 2 and the flow channel plate body 1. (2) A first guide surface 22 is formed at the second flow channel 21 of the flow channel plate 2. The first guide surface 22 is correspondingly set at the interface 12 so as to guide the flow direction of the working medium through the first guide surface 22, which can reduce the flow resistance of the working medium in the working medium flow channel and prevent the formation of a dead water area at the connection and cooperation of the flow channel plate body 1 and the flow channel plate 2 in the working medium flow channel, and avoid impurities from depositing and blocking the channel. (3) A second guide surface 14 is provided on the main body of the flow channel plate 1. The second guide surface 14 is formed at the corner position of the first flow channel section 111 and the second flow channel section 112 in the first flow channel section 11, so as to reduce the flow resistance of the working medium from the first flow channel section 111 to the second flow channel section 112 or from the second flow channel section 112 to the first flow channel section 111, and ensure the flow effect of the working medium in the first flow channel section 11.

[0080] (4) The second flow channel portion 21 can be formed on the raised portion 23 on the flow channel plate 2, so that the second flow channel portion 21 open to the flow channel plate body 1 can be formed on the flow channel plate 2 without increasing the thickness of the flow channel plate 2; (5) The second flow channel section 21 can be formed on the boss 24 on the flow channel plate 2, thereby ensuring the flatness of the surface of the flow channel plate 2 on the side away from the flow channel plate body 1, so as to facilitate the installation and arrangement of the flow path integration module 100 in the air conditioning system.

[0081] According to an embodiment of this application, the air conditioning system includes the flow path integration module 100 described above.

[0082] The advantages of the air conditioning system compared to existing technologies are the same as those of the flow path integration module 100 mentioned above, and will not be repeated here.
