Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a manifold assembly and heat exchanger. Background Technology

[0002] The main function of the manifold is to transport and distribute the concentrated fluid to multiple heat exchange tubes. However, since there is a certain distance between the multiple heat exchange tubes, the fluid pressure at different locations of the heat exchange tubes is different. Near the area with higher fluid pressure, the flow rate in the heat exchange tube will be larger, while near the area with lower fluid pressure, the flow rate in the heat exchange tube will be smaller. This causes uneven fluid flow rate in multiple heat exchange tubes, thus affecting the heat exchange effect of the heat exchanger. Utility Model Content

[0003] Therefore, it is necessary to provide a flow collection component that promotes uniform fluid distribution while satisfying the flow distribution requirements.

[0004] A current collection assembly includes a current collection box and a flow-dispersing structure. The current collection box includes a first cover and a second cover that are fastened to each other, forming a current collection cavity. One of the first cover and the second cover is provided with a plurality of spaced-apart mounting ports, each of which communicates with the current collection cavity and is used to insert a heat exchange tube. The flow-dispersing structure is assembled inside the current collection cavity and includes a plurality of flow-dispersing elements extending into the current collection cavity, spaced apart within the current collection cavity.

[0005] It is understandable that the first and second covers are configured to form a flow collection cavity to concentrate and gather the fluid, and through the assembly port, they are connected to multiple heat exchange tubes, thereby distributing the fluid to the multiple heat exchange tubes. By setting a turbulence structure in the flow collection cavity, the fluid can be agitated, making the fluid more dispersed and the fluid pressure distribution more uniform, thus promoting the uniformity of fluid distribution.

[0006] In one embodiment, a baffle is provided between any two adjacent assembly ports; or, at least two assembly ports are provided between any two adjacent baffles.

[0007] It is understandable that a flow-disrupting element is provided between any two adjacent assembly ports, and each assembly port has a flow-disrupting element near it to disturb the fluid, which helps to enhance the flow-disrupting effect; at least two assembly ports are provided between any two adjacent flow-disrupting elements, which enhances the smoothness of fluid flow on the basis of promoting disturbance.

[0008] In one embodiment, a group of multiple spoilers arranged at intervals along a first direction is formed; multiple groups of spoilers are arranged at intervals along a second direction, and the spoilers in any two adjacent groups of spoilers are staggered along the first direction; the first direction and the second direction are set at an angle.

[0009] Understandably, this setting enhances the resistance to fluid flow and improves the disturbance effect.

[0010] In one embodiment, at least a portion of the spoiler extends along a third direction, and at least one end of the spoiler is connected to at least one of the first cover and the second cover; and / or, at least a portion of the spoiler extends along a second direction, and at least one end of the spoiler is connected to the first cover or the second cover.

[0011] Understandably, by defining the extension direction of the baffle, the disturbance of fluid at different directions and positions can be satisfied. The first cover and / or the second cover can support the baffle and facilitate its assembly and fixation.

[0012] In one embodiment, the turbulence member has a limiting portion at at least one end along its extension direction, the limiting portion being located outside the flow collection cavity and abutting against the first cover or the second cover.

[0013] Understandably, the setting of the limiting part can enhance the stability of the spoiler assembly.

[0014] In one embodiment, the collection chamber includes at least two spaced sub-cavities, each of which is provided with a plurality of communicating assembly ports; at least two of the sub-cavities are arranged along a second direction; the collection box is provided with a liquid inlet, and the collection assembly further includes a liquid inlet pipe, one end of which passes through the liquid inlet and extends into a sub-cavity located at the end along the second direction; the collection box is provided with a liquid outlet, and the collection assembly further includes a liquid outlet pipe, one end of which passes through the liquid outlet and extends into a sub-cavity located at the beginning along the second direction.

[0015] Understandably, having at least two sub-cavities facilitates the assembly of more heat exchanger tube assemblies. The placement of the inlet and outlet pipes allows fluid to flow into the outermost sub-cavity and out of the innermost sub-cavity. The inlet and outlet can be integrated into a manifold. When the manifold is connected to external piping, the external piping connects directly to the corresponding inlet and outlet pipes on one side of the manifold. This eliminates the need for long external piping with numerous bends, thus optimizing the piping layout.

[0016] In one embodiment, at least a portion of the spoiler is hollow, and / or at least a portion of the spoiler is constructed with a plurality of spaced-apart spoiler holes along its own axial direction.

[0017] It is understood that at least some of the aforementioned baffles are hollow, which helps to reduce weight and lower costs. At least some of the aforementioned baffles are constructed with multiple spaced baffle holes along their own axial direction, which can change the fluid flow state and enhance the disturbance effect on the fluid.

[0018] In one embodiment, the multiple spaced-apart turbulence holes along the axial direction of the turbulence element constitute a turbulence hole group, and the turbulence element is provided with multiple groups spaced apart along its circumference, with the turbulence holes in the multiple groups interconnected; and / or, the aperture sizes of the multiple turbulence holes are different.

[0019] Understandably, with this configuration, each of the turbulence holes can serve as either an inlet or outlet for fluid flow, enhancing both the disturbance and the flow of the fluid. The different diameters of the various turbulence holes result in different effects on the fluid, thus enhancing the overall disturbance state.

[0020] In one embodiment, the turbulence structure is provided with a plurality of spaced-apart turbulence protrusions and / or a plurality of spaced-apart turbulence recesses.

[0021] It is understandable that by setting up turbulent protrusions or concave sections, the fluid flow state can be changed, and the effect of turbulence on the fluid can be enhanced.

[0022] In one embodiment, a plurality of the turbulence protrusions and turbulence recesses are arranged alternately in a spiral shape.

[0023] Understandably, this setup enhances the disturbance effect on the fluid, promotes improved fluid flow, and simplifies processing.

[0024] This application also provides a heat exchanger, including a heat exchange tube assembly and the above-mentioned manifold assembly; the manifold assembly is respectively installed at both ends of the heat exchange tube assembly along its own length direction; the heat exchange tube assembly includes a plurality of spaced heat exchange tubes, and each heat exchange tube is respectively inserted into the corresponding assembly port on both sides along its own axial direction.

[0025] It is understandable that heat exchange tubes exchange heat with air through heat exchange tube bundles. By setting up the aforementioned flow collectors, the uniformity of fluid distribution in the heat exchange tube bundles can be promoted, thereby improving heat exchange efficiency.

[0026] In one embodiment, the heat exchange tube group is provided in at least two groups and arranged at intervals along a second direction, and the heat exchange tubes in any two adjacent heat exchange tube groups are staggered along a first direction.

[0027] Understandably, this configuration, along the second direction, increases the contact area between the heat exchanger and the airflow, thereby improving the heat exchange effect.

[0028] In one embodiment, the heat exchange tube assembly has a windward side and a leeward side spaced apart along a second direction, and the liquid inlet and liquid outlet on the collector assembly are both located on the windward side, with the liquid inlet being higher than the liquid outlet.

[0029] Understandably, this configuration, along the second direction, ensures that the fluid flow in the heat exchanger is opposite to the airflow direction, which facilitates convection and enhances the heat exchange effect. Simultaneously, the inlet being higher than the outlet allows the fluid to enter the collection chamber under gravity and flow downwards, thus enhancing fluid turbulence.

[0030] In one embodiment, the heat exchange tube group is provided as one set, with a liquid inlet at one end of the heat exchange tube group along its own length and a liquid outlet at the other end of the heat exchange tube group; or, the heat exchange tube group is provided as at least two sets, with at least two sets of heat exchange tube groups arranged at intervals along the second direction; the collection cavity is provided with multiple sub-cavities; each heat exchange tube group is connected to the corresponding sub-cavity at both ends along its own length; the number of sub-cavities is 2n, and the heat exchange tube group at one end along its own length has both the liquid inlet and the liquid outlet; or, the number of sub-cavities is 2n+1, and the heat exchange tube group at one end along its own length has a liquid inlet at one end and a liquid outlet at the other end of the heat exchange tube group; where n∈positive integers.

[0031] Understandably, setting up a single heat exchange tube assembly with corresponding inlet and outlet ports results in a simple structure suitable for scenarios with low heat exchange requirements. Setting up at least two heat exchange tube assemblies enhances the heat exchange effect, and the positions of the inlet and outlet ports can be adjusted according to the number of tubes to accommodate the reciprocating flow path of the fluid.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0052] Please see Figures 1 to 9This application provides a flow collection assembly 10, which includes a flow collection box 11. The flow collection box 11 includes a first cover 111 and a second cover 112 that are fastened to each other. The first cover 111 and the second cover 112 surround and form a flow collection cavity 101 to concentrate and collect fluid within the flow collection cavity 101. During assembly, the parts can be assembled into one of the first cover 111 and the second cover 112 first, and then the first cover 111 and the second cover 112 can be assembled and connected. In some embodiments, the first cover 111 and the second cover 112 are snap-fitted together to facilitate disassembly and maintenance at any time; in other embodiments, the first cover 111 and the second cover 112 can also be welded together.

[0053] like Figures 1 to 6 As shown, furthermore, one of the first cover 111 and the second cover 112 is constructed with a plurality of spaced-apart assembly ports 102, each assembly port 102 communicating with the collection cavity 101. Each assembly port 102 is used to insert a heat exchange tube 21, so as to divert the fluid in the collection cavity 101 to the respective heat exchange tube 21. During assembly, the heat exchange tube 21 is welded to the inner wall of the assembly port 102 to ensure sealing.

[0054] like Figures 1 to 6 As shown, the flow collector assembly 10 further includes a turbulence structure, which is installed inside the flow collector cavity 101. During the flow of fluid into the flow collector cavity 101, the turbulence structure promotes fluid agitation, resulting in a more uniform fluid pressure distribution. This facilitates the uniform distribution of fluid to each heat exchange tube 21, promoting uniform heat exchange between the fluid in the heat exchange tube 21 and the external air. Furthermore, because the turbulence structure promotes fluid agitation, it enhances heat exchange within the flow collector assembly 10.

[0055] like Figures 1 to 6 As shown, in an optional embodiment, the turbulence structure includes a plurality of turbulence members 131 extending in the flow collection cavity 101. The plurality of turbulence members 131 are spaced apart in the flow collection cavity 101 to generate a turbulence effect on the fluid at different positions in the flow collection cavity 101, thereby promoting uniform fluid distribution.

[0056] In summary, by incorporating a turbulence structure within the flow collector assembly 10, fluid agitation is promoted, leading to a more uniform fluid pressure distribution. This allows the fluid to be evenly distributed to each heat exchange tube 21, improving the heat exchange efficiency between the fluid in the heat exchange tube 21 and the external air. If the fluid flow rate in the heat exchange tube 21 is too high, the fluid in that tube cannot fully exchange heat with the air; conversely, if the fluid flow rate is too low, the corresponding heat transfer area cannot be fully utilized, affecting the heat exchange efficiency. Furthermore, the turbulence structure's effect on the fluid agitation can enhance the initial heat exchange within the flow collector assembly 10, further increasing the overall heat exchange effect.

[0057] For ease of explanation, the height direction of the manifold 10 is taken as the first direction, the axial direction of the liquid inlet 103 of the manifold 10 is taken as the second direction, the axial direction of the assembly port 102 is taken as the third direction, the first direction is taken as the z-axis, the second direction as the y-axis, and the third direction as the x-axis.

[0058] In some embodiments, multiple spoilers 131 are connected to form a single unit, that is, the spoiler structure is set as an integral structure, and the spoiler structure can be assembled once.

[0059] like Figure 3 or Figure 5 As shown, in a further embodiment, a flow-dispersing element 131 is provided between any two adjacent assembly ports 102. With this arrangement, the flow-dispersing element 131 is provided near each heat exchange tube 21, and the fluid near each heat exchange tube 21 can be turbulent, which is beneficial to improving the flow-diversion effect of the fluid.

[0060] like Figure 4 or Figure 6 As shown, in some embodiments, at least two mounting ports 102 are provided between any two adjacent flow disruptors 131. In this way, the number of flow disruptors 131 used can be reduced while promoting fluid turbulence, which helps to reduce costs, and at the same time reduces fluid flow resistance, so as to promote smooth fluid flow while promoting turbulence.

[0061] like Figure 4 and Figure 5 As shown, in an optional embodiment, a plurality of flow-disrupting elements 131 arranged at intervals along a first direction constitute a flow-disrupting group 13, enabling the flow-disrupting structure to generate a disturbance effect on the fluid along the first direction. Multiple flow-disrupting groups 13 are arranged at intervals along a second direction to generate a disturbance effect on fluids distributed differently along the second direction. Simultaneously, the flow-disrupting elements 131 in any two adjacent flow-disrupting groups 13 are staggered along the first direction. Thus, along the first direction, the flow-disrupting elements 131 can alternately generate disturbances on the fluid, thereby intensifying the disturbance and improving the disturbance effect.

[0062] like Figures 1 to 5 As shown, in an optional embodiment, at least a portion of the flow deflector 131 extends along a third direction, and at least one end of the flow deflector 131 is connected to at least one of the first cover 111 and the second cover 112 along the third direction. Thus, the fluid needs to be diverted in a second direction to bypass the flow deflector 131, enhancing the flow deflection effect.

[0063] like Figure 6As shown, in another alternative embodiment, at least a portion of the flow disruptor 131 extends along a second direction, and at least one end of the flow disruptor 131 is connected to the first cover 111 or the second cover 112 along the second direction. Thus, the fluid is diverted in a third direction to bypass the flow disruptor 131, enhancing the flow disruption effect.

[0064] like Figure 2 As shown, in a specific embodiment, at least one of the first cover 111 and the second cover 112 includes a base plate 1111 and a bent section 1112 connected to the base plate 1111. The bent section 1112 surrounds the base plate 1111 and is angled to the base plate 1111. Taking the first cover 111 including the base plate 1111 and the bent section 1112, and the second cover 112 being a cover plate as an example, the cover plate covers the end of the bent section 1112 away from the base plate 1111 and is connected to the bent section 1112. When the spoiler 131 extends along a third direction, one end of the spoiler 131 along its own length direction is connected to the base plate 1111 or the cover plate; or, when the spoiler 131 extends along a third direction, one end of the spoiler 131 along its own length direction is connected to the base plate 1111, and the other end is connected to the cover plate; when the spoiler 131 extends along a second direction, at least one end of the spoiler 131 along its own length direction is connected to the bent section 1112.

[0065] like Figure 1 and Figure 2 As shown, in a specific embodiment, at least one end of the deflector 131 along its extension direction is provided with a limiting portion 1314. The limiting portion 1314 is located outside the flow collecting cavity 101 and abuts against the first cover 111 or the second cover 112. By providing the limiting portion 1314, the mating area between the deflector 131 and the first cover 111 or the second cover 112 is increased, thereby improving assembly reliability.

[0066] For example, the spoiler 131 extends in a third direction, one end of the spoiler 131 is connected to the inner wall of the first cover 111, and the other end of the spoiler 131 passes through the second cover 112 and abuts against the outer surface of the second cover 112 through the limiting part 1314 to restrict the movement of the spoiler 131 in a third direction. The second cover 112 has a limiting and supporting function for the spoiler 131 in the radial direction.

[0067] Specifically, the surface of the spoiler 131 is coated with a solder layer. After the spoiler 131 is initially assembled, it forms a solid connection with the first cover 111 and the second cover 112 through the melting of the solder layer, and ensures the sealing performance.

[0068] The limiting portion 1314 provided when the spoiler 131 extends in the second direction can also refer to the embodiment when the spoiler 131 extends in the third direction, and will not be described in detail here.

[0069] In a specific embodiment, the flow-disrupting element 131 can be configured as a pin, a round tube, etc., to form a smooth surface to promote fluid flow and reduce stagnation. This is only an example.

[0070] like Figure 7 As shown, in an optional embodiment, the turbulence structure is provided with a plurality of spaced-apart turbulence protrusions 1311 and / or a plurality of spaced-apart turbulence recesses 1312 to increase the contact area with the fluid, making the surface of the turbulence structure uneven, intensifying the turbulence effect on the fluid, and enhancing heat transfer. Specifically, each turbulence element 131 in the turbulence structure is provided with the aforementioned turbulence protrusions 1311 and / or turbulence recesses 1312.

[0071] like Figure 7 As shown, in a further embodiment, a plurality of turbulence protrusions 1311 and turbulence recesses 1312 are arranged alternately in a spiral shape, so that the fluid can be turbulently disturbed in a spiral manner, thereby enhancing the turbulence effect.

[0072] In a specific embodiment, the turbulence protrusion 1311 can be configured as toothed, that is, teeth are arranged continuously along the length direction of the turbulence member 131. The sharp shape of the teeth can enhance the turbulence effect on the fluid.

[0073] like Figure 8 As shown, in a specific embodiment, at least some of the flow-deflecting elements 131 are constructed with a plurality of spaced flow-deflecting holes 1313 along their own axial direction. The flow-deflecting elements 131 are radially recessed to form flow-deflecting holes 1313 in order to enhance the flow of the fluid.

[0074] Furthermore, the turbulence hole 1313 is provided radially through the turbulence member 131, which facilitates the fluid to pass through the turbulence member 131 from the turbulence hole 1313, thereby creating a turbulence effect on the fluid.

[0075] like Figure 8 As shown, more specifically, a group of turbulence holes 1313 arranged at intervals along the axial direction of the turbulence member 131 is a group of turbulence holes. The turbulence member 131 is provided with multiple groups at intervals along its circumference. The turbulence holes 1313 in the multiple groups of turbulence holes are interconnected. Fluid can flow in from any one of the turbulence holes 1313 and flow out from other different turbulence holes 1313. While enhancing the turbulence effect, it also allows the fluid to flow out from multiple turbulence holes 1313, reducing stagnation.

[0076] In some specific embodiments, the apertures of the multiple turbulence holes 1313 are different, and the turbulence holes 1313 with different apertures have different turbulence effects on the fluid, which also helps to enhance the turbulence effect.

[0077] Furthermore, in a group of turbulence holes, along the axial direction of the turbulence element 131, the diameter of the turbulence hole 1313 gradually increases from the assembly port 102 toward the second cover 112. This arrangement can enhance the turbulence effect on the fluid far from the assembly port 102, allowing the fluid to be fully turbulent and spread evenly in the collection cavity 101 before flowing into the heat exchange tube from the assembly port 102. Meanwhile, the diameter of the turbulence hole 1313 near the assembly port 102 is set to be smaller, which is beneficial for the fluid to flow smoothly into the heat exchange tube 21 when it is close to the assembly port 102, thus improving the fluid flow stability.

[0078] like Figure 9 As shown, in a specific embodiment, at least part of the spoiler 131 is hollow, that is, the spoiler 131 is provided with a spoiler hole 1313 that penetrates at least one side of the spoiler 131 along the axial direction, which helps to reduce material usage, reduce costs and lighten the weight of the spoiler 131, and improve assembly efficiency.

[0079] like Figures 1 to 6 As shown, in an optional embodiment, the manifold 101 includes at least two spaced sub-cavities 1011, each sub-cavity 1011 having a plurality of connected assembly ports 102. By providing a plurality of sub-cavities 1011, each sub-cavity 1011 can be connected to different heat exchange tube groups 20.

[0080] In a specific embodiment, the current collection assembly 10 further includes at least one partition plate 12, which is disposed in the current collection cavity 101 and divides the current collection cavity 101 into at least two spaced sub-cavities 1011. The partition plate 12 is welded to the first cover 111 and the second cover 112 to ensure the connection is sealed.

[0081] In other embodiments, at least two spaced sub-cavities 1011 may be formed by fastening together the first cover 111 and the second cover 112.

[0082] like Figure 1 and Figure 2 As shown, in a further embodiment, the partition plate 12 is provided with an insertion portion 121, and the second cover 112 is provided with a mating opening 1121. The insertion portion 121 is inserted into the mating opening 1121 to form a limiting fit. More specifically, the surface of the partition plate 12 is coated with solder. The solder is melted by high temperature, and the solder can fill the gap between the insertion portion 121 and the wall of the mating opening 1121, as well as the gap between the partition plate 12 and the first cover 111, thereby forming a welded connection.

[0083] like Figures 1 to 6As shown, in a further embodiment, at least two sub-cavities 1011 are arranged along the second direction; the collector box 11 is provided with a liquid inlet 103, and the collector assembly 10 further includes a liquid inlet pipe 14, one end of which passes through the liquid inlet 103 and the other end extends into a sub-cavity 1011 located at the end along the second direction, so as to first transport the fluid to the last sub-cavity 1011; the collector box 11 is provided with a liquid outlet 104, and the collector assembly 10 further includes a liquid outlet pipe 15, which... One end of the liquid pipe 15 passes through the liquid outlet 104 and extends into the sub-cavity 1011 located at the beginning along the second direction. The fluid enters the heat exchange tube 21 from the end sub-cavity 1011 and eventually returns to the beginning sub-cavity 1011 after multiple reciprocating heat exchanges in multiple heat exchange tubes 21. Therefore, this arrangement allows the fluid to be discharged from the beginning sub-cavity 1011. Along the second direction, the overall flow direction of the fluid is from the end sub-cavity 1011 to the beginning.

[0084] like Figure 5 As shown, in some embodiments, a flow-disrupting element 131 is provided at the port of a sub-cavity 1011 located at the end along the second direction where the inlet pipe 14 extends. The flow-disrupting element 131 is disposed opposite to the port so that the fluid collides with the flow-disrupting element 131 as soon as it enters the sub-cavity 1011, thereby promoting flow disturbance.

[0085] like Figures 10 to 13 As shown, this application also provides a heat exchanger 100, including a heat exchange tube assembly 20 and the aforementioned manifold 10. The heat exchange tube assembly 20 has manifold 10s mounted at both ends along its length. The heat exchange tube assembly 20 includes multiple spaced heat exchange tubes 21, each heat exchange tube 21 being inserted into corresponding mounting ports 102 on both sides along its axial direction. Thus, fluid in the manifold 10 on one side of the heat exchange tube assembly 20 is diverted into each heat exchange tube 21 within the heat exchange tube assembly 20. After heat exchange, it can flow to the manifold 10 on the other side of the heat exchange tube assembly 20 and re-converge. By using the aforementioned manifold 10, the fluid diverted into the heat exchange tubes 21 can be more uniform, which helps to improve heat exchange efficiency and enhance the overall performance of the heat exchanger 100. The length direction of the heat exchange tube assembly 20 is also the third direction.

[0086] In some embodiments, the heat exchange tube assembly 20 has a turbulence-inducing structure at one end of its length direction and no turbulence-inducing structure at the other end; or, the heat exchange tube assembly 20 has a turbulence-inducing structure at both ends of its length direction.

[0087] like Figure 10 and Figure 13As shown, in a further embodiment, the heat exchange tube assembly 20 is provided with an air-facing surface 201 and a leeward surface 202 spaced apart along the second direction. Airflow blows from the air-facing surface 201 to the leeward surface 202, and the fluid exchanges heat with the external airflow through the heat exchange tubes 21. The sub-cavity 1011 located at the beginning along the second direction is close to the air-facing surface 201, and the sub-cavity 1011 located at the end along the second direction is close to the leeward surface 202. Furthermore, the liquid inlet 103 and liquid outlet 104 on the collector assembly 10 are both located on the air-facing surface 201. With this arrangement, the fluid flows into the heat exchange tube assembly 20 from the last sub-cavity 1011 along the second direction, and after heat exchange in the heat exchange tube assembly 20, flows out from the first sub-cavity 1011. Along the second direction, the fluid flow direction is opposite to the airflow direction, forming convection, ensuring that the airflow and fluid maintain a certain temperature difference along the second direction, thereby ensuring heat exchange efficiency.

[0088] like Figure 12 As shown, in other embodiments, the sub-cavity 1011 at the beginning of the second direction is close to the leeward side 202, and the sub-cavity 1011 at the end of the second direction is close to the windward side 201, so that the fluid flow direction is the same as the airflow direction along the second direction.

[0089] like Figure 2 As shown, in a further embodiment, the inlet 103 is higher than the outlet 104. With this configuration, the fluid entering from the inlet 103 flows downward under the action of gravity, promoting fluid turbulence. At the same time, the fluid can also flow out naturally from the outlet 104 under the action of gravity.

[0090] like Figure 12 As shown, in some embodiments, the heat exchange tube assembly 20 is provided with one set. The flow collector 10 at one end of the heat exchange tube assembly 20 along its own length direction is provided with a liquid inlet 103, and the flow collector 10 at the other end is provided with a liquid outlet 104. The fluid flows directly into the flow collector 101 at one end from the liquid inlet 103, is split and enters the heat exchange tube assembly 20, and then flows from the heat exchange tube assembly 20 into the flow collector 101 at the other end, re-converges, and finally flows out from the liquid outlet 104 of the flow collector 101 at the other end.

[0091] like Figures 10 to 12As shown, in a further embodiment, along the second direction, the heat exchange tube group 20 is provided with at least two groups and arranged at intervals along the second direction. Each heat exchange tube group 20 is connected to a sub-cavity 1011 at both ends along its own length direction. With this arrangement, along the second direction, the fluid first enters the last sub-cavity 1011 and then flows into the heat exchange tube group 20 at the leeward side 202. After heat exchange, it flows into the sub-cavity 1011 at the other end of the heat exchange tube group 20 at the leeward side 202, re-converges, and then flows into the adjacent heat exchange tube group 20 again. This process is repeated, thereby forming a tortuous fluid flow pattern along the second direction, so as to prolong the fluid flow time, increase the heat exchange area, and improve the heat exchange effect.

[0092] Along the second direction, the heat exchange tubes 21 in any two adjacent heat exchange tube groups 20 are staggered along the first direction. This arrangement allows for full utilization of space as the airflow moves from the windward side 201 to the leeward side 202, promoting sufficient contact between the different heat exchange tube groups 20 and the airflow, thereby improving the heat exchange effect.

[0093] like Figures 10 to 12 As shown, in a further embodiment, the number of sub-cavities 1011 is 2n. The heat exchange tube assembly 20 has a liquid inlet 103 and a liquid outlet 104 at one end along its own length direction. That is, the liquid inlet 103 and the liquid outlet 104 are set on the same side, which facilitates the assembly of the liquid inlet pipe 14 and the liquid outlet pipe 15 on the same side, which helps to reduce pipe crossing and reduce space occupation. At this time, the liquid inlet 103 and the liquid outlet 104 are not set on the other side, or the liquid inlet 103 and the liquid outlet 104 are blocked.

[0094] In other embodiments, the number of sub-cavities 1011 is 2n+1. The heat exchange tube assembly 20 has a liquid inlet 103 at one end along its length direction and a liquid outlet 104 at the other end. That is, the liquid inlet 103 and the liquid outlet 104 are arranged on opposite sides to accommodate the corresponding number of heat exchange tube assemblies 20.

[0095] It should be noted that n ∈ positive integers.

[0096] In some embodiments, the heat exchanger 100 further includes fins, with fins fitted in any two adjacent heat exchange tubes 21. By setting fins, the contact area with air is increased, thereby enhancing the heat exchange effect. For example, the fins can be configured as window fins, bridge fins, flat fins, etc.

[0097] In some embodiments, the heat exchange tube 21 is configured as a microchannel flat tube, which has a large surface area and a small flow cross-sectional area, which helps to increase the contact area between the fluid and the tube and improve the heat transfer efficiency.

[0098] like Figures 10 to 13As shown, in some embodiments, the heat exchanger 100 further includes a side plate 30. Along the first direction, the side plate 30 is provided on at least one side of the heat exchange tube group 20. The side plate 30 presses against the outermost fins along the first direction, so that the fins are more closely attached to the corresponding heat exchange tubes 21, thereby improving the thermal performance and promoting heat exchange.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
