[0053] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0054] like Figures 1 to 9 As shown, according to the first aspect of the embodiment of the present application, a heat exchange plate-fin structure 10 is proposed, including: a flow path layer 100, formed with a first input hole 101, a first output hole 102 and a plurality of flow grooves 103, the two ends of the flow groove 103 are respectively connected to the first input hole 101 and the first output hole 102, and the plurality of flow grooves 103 are arranged at intervals; a plate-shaped layer 200, arranged on the flow path layer 100, the plate-shaped layer 200 covers the flow grooves 103 to form a first medium flow path 11 with the flow path layer 100, a raised portion 600, arranged on the plate-shaped layer 200, along the spacing direction of the plurality of flow grooves 103, the raised portion 600 is arranged on one side of the flow groove 103; wherein the raised portion 600 is formed with a through hole 601 that is conductive along the spacing direction of the plurality of flow grooves 103.

[0055] The heat exchange plate-fin structure 10 provided in the embodiment of the present application includes a flow path layer 100, a plate-shaped layer 200 and a protrusion 600, wherein the flow path layer 100 is formed with a plurality of flow grooves 103, the plate-shaped layer 200 is arranged on the flow path layer 100 and covers the plurality of the aforementioned flow grooves 103, so that the plate-shaped layer 200 and the flow path layer 100 can enclose a plurality of first medium flow paths 11 to provide a flow path for the medium to be heat exchanged during use; the flow path layer 100 is also formed with a first input hole 101 and a first output hole 102, one end of the aforementioned flow groove 103 is connected to the aforementioned first input hole 101, and the other end is connected to the first output hole 102, so that the medium to be heat exchanged can flow into the heat exchange plate-fin structure 10 through the aforementioned first input hole 101, and further discharge the heat exchange plate-fin structure 10 through the aforementioned first output hole 102 after flowing through the first medium flow path 11.

[0056] Therefore, based on the above-mentioned settings, the heat exchange plate-fin structure 10 provided in the embodiment of the present application can distribute the heat exchange medium that is relatively concentrated when input to each first medium flow path 11, thereby improving the dispersion of the heat exchange medium. When there is heat exchange medium in the first medium flow path 11, the heat exchange medium in each first medium flow path 11 can absorb heat from the external environment or release heat to the external environment through the plate-shaped layer 200 and the flow path layer 100, thereby helping to improve the heat exchange area utilization rate of the heat exchange plate-fin structure 10, and improving the heat exchange efficiency of the heat exchange plate-fin structure 10. It is beneficial to ensure the compactness of the heat exchange plate-fin structure 10 while improving the heat exchange performance of the heat exchange plate-fin structure 10, and improve the miniaturization and lightweight level of the heat exchange plate-fin structure 10, which is beneficial to reducing the volume and mass of the heat exchange device and the air conditioner in practical applications. After heat exchange, the heat exchange medium in each first medium flow path 11 can be further output in a concentrated manner through the first output hole 102, which can provide a guarantee for the convenience of medium output of the heat exchange plate-fin structure 10.

[0057] like Figure 1 As shown, the aforementioned protrusion 600 is arranged on the aforementioned plate-shaped layer 200 and is arranged on one side of the circulation groove 103 along the spacing direction of the plurality of aforementioned circulation grooves 103. Therefore, based on the setting of the aforementioned protrusion 600, the surface unevenness of the heat exchange plate-fin structure 10 can be improved along the spacing direction of the plurality of aforementioned circulation grooves 103, and the protrusion 600 is formed with a through hole 601, and the aforementioned through hole 601 is conductive along the spacing direction of the plurality of aforementioned circulation grooves 103. Therefore, during use, when the fluid medium in the external environment used for heat exchange with the aforementioned heat exchange medium flows through the outside of each first medium flow path 11 along the spacing direction of the plurality of aforementioned circulation grooves 103, the aforementioned protrusion 600 can play a cutting role on the aforementioned fluid medium, which is beneficial to maintaining a thinner temperature boundary layer during the heat exchange process, further improving the heat transfer rate of the heat exchange plate-fin structure 10, and further enhancing the heat exchange performance of the heat exchange plate-fin structure 10.

[0058] It should be noted that Figure 1 The dashed line with an arrow in the middle is used to schematically represent the flow direction of the fluid medium in the external environment when it flows along the spacing direction of the plurality of aforementioned flow grooves.

[0059] It can be understood that the aforementioned medium to be heat exchanged can be but is not limited to refrigerant; the aforementioned fluid medium used for exchanging heat with the aforementioned medium to be heat exchanged can be but is not limited to air.

[0060] It should be noted that the heat exchange plate-fin structure 10 provided in the embodiment of the present application can be used as a component of a heat exchange device or an air conditioner in practical applications. During use, the installation position of the heat exchange plate-fin structure 10 can be adjusted so that the fluid medium in the external environment can flow through the heat exchange plate-fin structure 10 along the spacing direction of the multiple first medium flow paths 11, so that the aforementioned fluid medium can pass through the outside of each first medium flow path 11 in sequence when flowing through the heat exchange plate-fin structure 10, and then exchange heat with the medium to be heat exchanged in the first medium flow path 11. Taking the aforementioned heat exchange plate-fin structure 10 applied to an air conditioner as an example, the spacing direction of the aforementioned multiple first medium flow paths 11 can be used to be arranged along the air supply direction of the air supply device of the air conditioner, so that the airflow output by the aforementioned air supply device can pass through the outside of each first medium flow path 11 in sequence. In the process of the aforementioned fluid medium flowing through the outside of each first medium flow path 11 along the spacing direction of the plurality of aforementioned flow grooves 103, if the surface of the heat exchange plate-fin structure 10 is flat, the temperature boundary layer during heat exchange will increase as the flow distance of the aforementioned fluid medium increases, thereby resulting in a decrease in the heat transfer rate, which is not conducive to fully exerting the heat exchange performance of the heat exchange plate-fin structure 10; the heat exchange plate-fin structure 10 provided in the embodiment of the present application is based on the setting of the aforementioned raised portion 600, which can enhance the surface unevenness of the heat exchange plate-fin structure 10, thereby improving the heat transfer rate of the heat exchange plate-fin structure 10, and achieving further enhancement of the heat exchange performance of the heat exchange plate-fin structure 10.

[0061] like Figure 8 and Fig. 9 As shown, taking the heat exchange plate-fin structure 10 as a component of the heat exchange device as an example, multiple aforementioned heat exchange plate-fin structures 10 can be stacked and arranged, and the first input holes 101 of each heat exchange plate-fin structure 10 are sequentially connected, and the first output holes 102 of each heat exchange plate-fin structure 10 are sequentially connected, so that each first heat exchange plate-fin structure 10 forms a parallel relationship, and then the medium to be heat exchanged can be distributed to the corresponding heat exchange plate-fin structure 10 through each first input hole 101, and flow through the first medium channel of each heat exchange plate-fin structure 10 for heat exchange, and the medium to be heat exchanged can be further output in a centralized manner through each first output hole 102 after heat exchange. Among the multiple heat exchange plate-fin structures 10, a gap can be formed between two adjacent heat exchange plate-fin structures 10, and the aforementioned gap can be used as a second medium flow path 12, and the second medium flow path 12 can be used for the circulation of fluid medium in the external environment, so as to facilitate heat exchange between the medium to be heat exchanged and the aforementioned fluid medium. It can be understood that the aforementioned fluid medium can be but not limited to air.

[0062] For example, when the heat exchange plate-fin structure 10 is used as a component of a heat exchange device, the first input hole 101 and the first output hole 102 can be arranged along the direction of gravity, so that the first medium flow path 11 can maintain a high verticality. When the aforementioned heat exchange device is used as an evaporator, the condensed water generated on the surface of the heat exchange plate-fin structure 10 can drip under the action of gravity, thereby improving the drainage performance of the heat exchange device and preventing the condensed water from occupying a large area of ​​the second medium flow path 12, which is beneficial to reducing the resistance of the aforementioned fluid medium when flowing through the second medium flow path 12, thereby further exerting the heat exchange performance of the heat exchange device.

[0063] It is understandable that if Figures 1 to 6 As shown, the flow path layer 100 and the plate layer 200 can both be sheet structures, which is beneficial for reducing the overall volume and mass of the heat exchange plate-fin structure 10 while ensuring the heat exchange area of ​​the heat exchange plate-fin structure 10, thereby improving the compactness of the heat exchange plate-fin structure 10.

[0064] It is understandable that if Figure 2 As shown, the flow path layer 100 can be provided with the aforementioned first input hole 101 and the first output hole 102 along its thickness direction, and the first input hole 101 and the first output hole 102 are arranged at intervals. The aforementioned multiple flow grooves 103 are opened in the flow path layer 100 and are located between the first input hole 101 and the first output hole 102, so as to establish a connection relationship between the first input hole 101, the first output hole 102 and the flow grooves 103, and ensure that the flow grooves 103 can have a relatively high opening length, so as to further ensure the heat exchange effect of the heat exchange medium when flowing through the first medium flow path 11.

[0065] It is understandable that if Figure 2 As shown, the flow slot 103 is an open slot, that is, a notch of the flow slot 103 can be formed on one side of the flow path layer 100, which is conducive to reducing the difficulty of forming the flow slot 103. Accordingly, the plate-shaped layer 200 covers the flow slot 103, that is, the plate-shaped layer 200 is arranged on the side of the notch of the flow path layer 100 formed with the flow slot 103 and covers the aforementioned notch, so that the plate-shaped layer 200 and the flow path layer 100 can enclose the aforementioned first medium flow path 11 based on the groove space of the flow slot 103. At the same time, since the first medium flow path 11 is formed based on the groove space of the flow slot 103, the spacing direction of the aforementioned multiple flow slots 103 is also the spacing direction of the multiple first medium flow paths 11.

[0066] It is understandable that if Figure 6As shown, in actual applications, in order to facilitate the processing of the aforementioned flow path groove, the flow path layer 100 may include a flow path portion 110 and a covering portion 120, wherein the flow path portion 110 may be provided with the aforementioned flow path groove, and the flow path portion 110 may have notches of the aforementioned flow path groove formed on both sides in the thickness direction, that is, the flow path groove may pass through along the thickness direction of the flow path portion 110, thereby improving the processing convenience of the flow path groove, and the aforementioned covering portion 120 and the aforementioned plate-shaped layer 200 may be respectively arranged on both sides of the flow path portion 110 to cover the notches on both sides of the aforementioned flow path groove to enclose the aforementioned first medium flow path 11.

[0067] It is understandable that if Figure 6 As shown, the cross-sectional shape of the circulation groove 103 can be set according to actual needs. For example, the cross-sectional shape of the circulation groove 103 can be a triangle, a quadrilateral, an arcuate shape, etc., which is not limited too much here.

[0068] In some examples, the plate-shaped layer 200 is diffusion bonded to the flow path layer 100 .

[0069] In this technical solution, the plate-shaped layer 200 and the flow path layer 100 are connected by diffusion bonding. On the one hand, the tightness of the connection between the plate-shaped layer 200 and the flow path layer 100 can be ensured, and a gap between the plate-shaped layer 200 and the flow path layer 100 can be avoided, thereby reducing the possibility of leakage of the medium to be exchanged in the first medium flow path 11; on the other hand, the connection strength between the plate-shaped layer 200 and the flow path layer 100 can be ensured, thereby further improving the adaptability of the heat exchange plate-fin structure 10 to high-pressure working conditions, which is conducive to broadening the heat exchange plate-fin structure 10. On the one hand, it can reduce the plastic deformation of the plate-shaped layer 200 and the flow path layer 100 when they are connected, and reduce the possibility of large-scale deformation of the flow groove 103 during the connection process, which is beneficial to further ensure the molding accuracy of the first medium flow path 11. In the process of manufacturing the heat exchange plate-fin structure 10, the possibility of blockage of the first medium flow path 11 can be reduced, and the production yield rate of the heat exchange plate-fin structure 10 can be improved, thereby ensuring the heat exchange performance of the heat exchange plate-fin structure 10.

[0070] For example, Figure 6 As shown, in practical applications, the joining position or joining surface of the flow path layer 100 and the plate-shaped layer 200 can have a higher flatness, which further facilitates the connection of the flow path layer 100 and the plate-shaped layer 200 by diffusion bonding, thereby reducing the possibility of stress irregularity during diffusion bonding.

[0071] It should be noted that when diffusion bonding between the flow path layer 100 and the plate-shaped layer 200 is actually carried out, the flow path layer 100 and the plate-shaped layer 200 can be pressurized and bonded at a temperature lower than the melting point of the plate-shaped layer 200 and the flow path layer 100 to avoid melting and deformation of the flow path layer 100 and the plate-shaped layer 200, thereby ensuring the molding accuracy of the heat exchange plate fin structure 10.

[0072] like Figure 1 , Figure 6 and Figure 7 As shown, in some examples, the heat exchange plate-fin structure 10 further includes: a current collecting member 300, which is arranged in the flow path layer 100, and a current collecting member 300 is arranged at each of the first input hole 101 and the first output hole 102; wherein the current collecting member 300 forms a current collecting flow path 301, and the two ends of the first medium flow path 11 are connected to the current collecting flow path 301 through the first input hole 101 and the first output hole 102, respectively.

[0073] In this technical solution, the heat exchange plate-fin structure 10 may further include a current collecting member 300 formed with a current collecting flow path 301, the current collecting member 300 is arranged on the aforementioned flow path layer 100, and a current collecting member 300 is arranged at the aforementioned first input hole 101 and the first output hole 102, respectively, the aforementioned current collecting flow path 301 is connected to the aforementioned first medium flow path 11, that is, the current collecting flow path 301 of the current collecting member 300 located at the first input hole 101 can be connected to one end of the first medium flow path 11 through the aforementioned first input hole 101, and the current collecting member 300 located at the first output hole 102 0 can be connected to the other end of the first medium flow path 11 through the aforementioned first output hole 102, so that the heat exchange plate-fin structure 10 can, based on the aforementioned setting, on the one hand, carry out centralized input and output of the medium to be exchanged through the aforementioned collecting piece 300 during use, thereby improving the convenience of medium circulation of the heat exchange plate-fin structure 10; on the other hand, when the heat exchange plate-fin structure 10 is used as a component of a heat exchange device, it is convenient to connect the multiple heat exchange plate-fin structures 10 included in the heat exchange device through the collecting piece 300, which is beneficial to improving the structural compactness of the heat exchange device.

[0074] like Figure 1 and Figure 3 As shown, in some examples, the plate-shaped layer 200 is formed with a second input hole 201 and a second output hole 202 , and the second input hole 201 and the second output hole 202 are connected to the first input hole 101 and the first output hole 102 , respectively.

[0075] In this technical solution, the plate-shaped layer 200 may also be formed with a second input hole 201 and a second output hole 202, wherein the second input hole 201 is connected to the first input hole 101, and the second output hole 202 is connected to the first output hole 102. Therefore, in practical applications, the heat exchange plate-fin structure 10 can be connected to an external device through the collecting parts 300 and the plate-shaped layer 200 on both sides of the flow path layer 100, respectively, thereby improving the connection convenience of the heat exchange plate-fin structure 10.

[0076] For example, Figure 8 As shown, when the heat exchange plate-fin structure 10 is applied to a heat exchange device, in two adjacent heat exchange plate-fin structures 10, each collecting piece 300 of one can be correspondingly connected to the second input hole 201 and the second output hole 202 of the other, so that the two adjacent heat exchange plate-fin structures 10 form a parallel relationship, which is convenient for the heat exchange device to evenly distribute the heat exchange medium to each heat exchange plate-fin structure 10, which is conducive to giving full play to the heat exchange performance of the heat exchange device.

[0077] In some examples, the distance from one end of the current collecting member 300 away from the flow path layer 100 to the flow path layer 100 is greater than or equal to 0.1 mm.

[0078] In this technical solution, the distance from one end of the current collecting piece 300 away from the flow path layer 100 to the flow path layer 100 can be greater than or equal to 0.1 mm, so that when the end of the current collecting piece 300 away from the aforementioned flow path layer 100 is used to connect other heat exchange plate-fin structures 10 or other devices, a certain distance can be formed between the aforementioned other heat exchange plate-fin structures 10 or other devices and the flow path layer 100 where the current collecting piece 300 is located, thereby avoiding contact between the aforementioned flow path layer 100 and other structures, which is beneficial for exposing the flow path layer 100 to the external environment more fully, thereby further improving the heat exchange performance of the heat exchange plate-fin structure 10.

[0079] In some feasible examples, the distance from one end of the current collecting member 300 away from the flow path layer 100 to the flow path layer 100 is greater than or equal to 0.1 mm and less than or equal to 10 mm, thereby avoiding the current collecting member 300 from being too long, which is beneficial to ensuring the compactness of the heat exchange plate-fin structure 10.

[0080] like Figure 2 As shown, in some examples, the first input hole 101 and the first output hole 102 are arranged at intervals along the first direction of the flow path layer 100, and the plurality of flow grooves 103 are arranged at intervals along the second direction of the flow path layer 100, and the length of the flow path layer 100 in the first direction is less than the length of the flow path layer 100 in the second direction.

[0081] In this technical solution, the first input hole 101 and the first output hole 102 can be arranged at intervals along the direction of the larger size of the flow path layer 100, so as to facilitate increasing the opening length of the circulation groove 103, so as to provide favorable conditions for increasing the heat exchange capacity of the medium to be heat exchanged. Accordingly, multiple circulation grooves 103 can be arranged at intervals along the direction of the smaller size of the flow path layer 100, which is conducive to further improving the compactness of the heat exchange plate-fin structure 10, reducing the volume and mass of the heat exchange plate-fin structure 10, and achieving further improvement in the lightweight and miniaturization of the heat exchange plate-fin structure 10.

[0082] It should be noted that Figure 2 The X direction is used to schematically represent the aforementioned second direction, and the Y direction is used to schematically represent the aforementioned first direction.

[0083] like Figure 1 , Figures 3 to 6 As shown, in some examples, there are multiple protrusions 600 , and at least one protrusion 600 is arranged between two adjacent flow slots 103 .

[0084] In this technical solution, the number of the aforementioned protrusions 600 can be multiple, and at least one protrusion 600 is arranged between two adjacent circulation grooves 103 among the multiple aforementioned circulation grooves 103, so as to further enhance the surface roughness of the heat exchange plate-fin structure 10, and when the fluid medium in the external environment flows through the outside of each first medium flow path 11, more protrusions 600 are used to cut the aforementioned fluid medium, further reduce the thickness of the temperature boundary layer, and achieve a further improvement in the heat transfer rate.

[0085] like Figures 3 to 6 As shown, in some examples, at least part of the protrusions 600 are located on the side of the plate-shaped layer 200 facing the flow path layer 100 ; and / or at least part of the protrusions 600 are located on the side of the plate-shaped layer 200 facing away from the flow path layer 100 .

[0086] In this technical solution, at least part of the multiple protrusions 600 can be arranged on the side of the plate-shaped layer 200 facing the flow path layer 100, which is beneficial to improve the compactness of the heat exchange plate-fin structure 10 and further improve the miniaturization level of the heat exchange plate-fin structure 10.

[0087] In this technical solution, at least part of the multiple protrusions 600 can be arranged on the side of the plate layer 200 that is away from the flow path layer 100, so as to avoid the flow path layer 100 blocking the protrusions 600, which is beneficial to further exert the cutting effect of the protrusions 600 on the fluid medium in the external environment, further reduce the temperature boundary layer, and further improve the heat transfer rate.

[0088] It is understandable that a portion of the plurality of protrusions 600 may be disposed on a side of the plate-shaped layer 200 facing the flow path layer 100 , and another portion may be disposed on a side of the plate-shaped layer 200 facing away from the flow path layer 100 .

[0089] like Figure 6 and Figure 8 As shown, in some examples, when the protrusion 600 is located on the side of the plate-shaped layer 200 facing the flow path layer 100, the distance from the end of the protrusion 600 away from the plate-shaped layer 200 to the plate-shaped layer 200 is greater than the distance from the end of the flow path layer 100 away from the plate-shaped layer 200 to the plate-shaped layer 200.

[0090] In this technical solution, when the protrusion 600 is arranged on the side of the plate-shaped layer 200 facing the flow path layer 100, in order to avoid the flow path layer 100 blocking the protrusion 600, the distance from the end of the protrusion 600 away from the plate-shaped layer 200 to the plate-shaped layer 200 can be set to be greater than the distance from the end of the flow path layer 100 away from the plate-shaped layer 200 to the plate-shaped layer 200, that is, the protrusion height of the protrusion 600 relative to the plate-shaped layer 200 is higher than the protrusion height of the flow path layer 100 relative to the plate-shaped layer 200, thereby ensuring and exerting a greater degree of the cutting effect of the protrusion 600 on the fluid medium in the external environment, further reducing the temperature boundary layer, and achieving a further improvement in the heat transfer rate.

[0091] like Figures 3 to 6 As shown, in some examples, the protrusion 600 and the plate-shaped layer 200 are an integral structure.

[0092] In this technical solution, the aforementioned protrusion 600 can be an integrated structure with the aforementioned plate-shaped layer 200, so that in the process of processing the heat exchange plate-fin structure 10, the aforementioned protrusion 600 and the aforementioned plate-shaped layer 200 can be made based on the same substrate. For example, the aforementioned protrusion 600 can be processed on the substrate of the aforementioned plate-shaped layer 200 through a stamping process, thereby reducing the difficulty of assembling the protrusion 600 and the plate-shaped layer 200 while improving the connection strength between the protrusion 600 and the plate-shaped layer 200.

[0093] In some examples, the plate-shaped layer 200 is made of an aluminum material or a stainless steel material; and / or the flow path layer 100 is made of an aluminum material or a stainless steel material.

[0094] In this technical solution, the plate-shaped layer 200 can be made of aluminum material or stainless steel material, which is beneficial to improve the thermal conductivity of the plate-shaped layer 200 and further improve the heat exchange performance of the heat exchange plate-fin structure 10.

[0095] Correspondingly, the flow path layer 100 can also be made of aluminum material or stainless steel material, which is beneficial to improve the thermal conductivity of the plate-shaped layer 200 and further improve the heat exchange performance of the heat exchange plate-fin structure 10.

[0096] like Figure 8 and Fig. 9 As shown, according to the second aspect of an embodiment of the present application, a heat exchange device is proposed, comprising: a plurality of heat exchange plate-fin structures 10 as proposed in any one of the first aspects above, the plurality of heat exchange plate-fin structures 10 being arranged in sequence along the conduction direction of the first input hole 101; wherein, in two adjacent heat exchange plate-fin structures 10, a gap is formed between the plate-shaped layer 200 of one and the flow path layer 100 of the other, so that a second medium flow path 12 is formed between the two adjacent heat exchange plate-fin structures 10.

[0097] The heat exchange device provided in the embodiment of the present application may include a plurality of the aforementioned heat exchange plate-fin structures 1010. The plurality of aforementioned heat exchange plate-fin structures 10 may be arranged in sequence along the conduction direction of the first input hole 101, so that the plurality of heat exchange plate-fin structures 10 form a stacked state, thereby improving the structural compactness of the heat exchange device, and facilitating the distribution of the medium to be exchanged to the corresponding first medium flow path 11 through each first input hole 101, thereby improving the distribution dispersion of the medium to be exchanged, and allowing the medium to be exchanged to flow through the first medium channel of each heat exchange plate-fin structure 10 to exchange heat with the external environment, thereby improving the heat exchange efficiency. In two adjacent heat exchange plate-fin structures 10, a gap may be formed between the plate-shaped layer 200 of one and the flow path layer 100 of the other, and the aforementioned gap may be used as a second medium flow path 12, and the second medium flow path 12 may be used for the circulation of fluid medium in the external environment, so as to facilitate heat exchange between the medium to be exchanged and the aforementioned fluid medium.

[0098] It can be understood that the aforementioned heat exchange medium can be but is not limited to refrigerant; the aforementioned fluid medium can be but is not limited to air.

[0099] For example, the first input hole 101 and the first output hole 102 of each heat exchange plate-fin structure 10 are arranged along the direction of gravity, so that the first medium flow path 11 can maintain a high verticality. When the aforementioned heat exchange device is used as an evaporator, the condensed water generated on the surface of the heat exchange plate-fin structure 10 can drip under the action of gravity, thereby improving the drainage performance of the heat exchange device and preventing the condensed water from occupying a large area of ​​the second medium flow path 12, which is conducive to reducing the resistance of the aforementioned fluid medium when it flows through the second medium flow path 12, and further exerting the heat exchange performance of the heat exchange device.

[0100] In some examples, when the heat exchange plate-fin structure 10 includes a current collecting member 300, in two adjacent heat exchange plate-fin structures 10, the first input hole 101 of one is connected to the second input hole 201 of the other through a current collecting flow path 301 of a current collecting member 300, and the first output hole 102 of one is connected to the second output hole 202 of the other through a current collecting flow path 301 of a current collecting member 300.

[0101] In this technical solution, when the heat exchange plate-fin structure 10 includes the aforementioned collecting member 300, in two adjacent heat exchange plate-fin structures 10, the first input hole 101 of one is connected with the second input hole 201 of the other through a collecting flow path 301 of a collecting member 300, and the first output hole 102 of one is connected with the second output hole 202 of the other through a collecting flow path 301 of a collecting member 300, thereby making the two adjacent heat exchange plate-fin structures 10 connected in parallel with each other. On the one hand, it is convenient for the centralized input and output of the heat exchange device and improves the connection convenience between the heat exchange device and other devices. On the other hand, the collecting member 300 can also be used to control the gap between the flow path layer 100 of one of the two adjacent heat exchange plate-fin structures 10 and the plate-shaped layer 200 of the other, so as to facilitate the formation of the second medium flow path 12 and further ensure the heat exchange performance of the heat exchange device.

[0102] In some feasible examples, in two adjacent heat exchange plate-fin structures 10, a gap is formed between the plate layer 200 of one and the flow path layer 100 of the other, and the length of the gap is greater than or equal to 0.1 mm and less than or equal to 10 mm, so as to reduce the resistance of the second medium flow path 12 to the aforementioned fluid medium while ensuring the structural compactness of the heat exchange device, thereby further improving the heat exchange performance of the heat exchange device.

[0103] In some feasible examples, the heat exchange device may also include a first end plate 20, a second end plate 30, a medium input pipe 40 and a medium output pipe 50, wherein the first end plate 20 and the second end plate 30 are arranged at intervals along the conduction direction of the aforementioned first input hole 101, and the plurality of aforementioned heat exchange plate-fin structures 10 are located between the first end plate 20 and the second end plate 30, the medium input pipe 40 and the medium output pipe 50 are passed through the aforementioned first end plate 20, and the medium input pipe 40 is connected to each first input hole 101, and the medium output pipe 50 is connected to the aforementioned first output hole 102, so that based on the aforementioned setting, the heat exchange device can use the first end plate 20 and the second end plate 30 to constrain and fix the plurality of heat exchange plate-fin structures 10, thereby improving the structural stability and reliability of the heat exchange device, and facilitating the centralized input and output of the medium to be exchanged through the medium input pipe 40 and the medium output pipe 50, respectively, thereby improving the convenience of use of the heat exchange device.
