Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a mounting bracket assembly, a modular heat exchanger, a heat exchange system, and a heat pump device. Background Technology

[0002] Existing large-scale heat pump equipment typically places the fan module above the heat exchanger to drive airflow and achieve heat exchange with the heat exchanger. To meet the heat exchange requirements of large-scale heat pump equipment, a large heat exchanger assembly is required to increase the overall heat exchange area and heat exchange capacity of the heat exchanger.

[0003] The common arrangement of heat exchangers is to set up multiple heat exchanger components in a V- or G-shape below the fan module. However, this arrangement can only increase the heat exchange area to a limited extent, and the volume of a single heat exchanger component is relatively large. This not only increases the equipment footprint, but also makes it impossible to flexibly adjust the number of heat exchanger components installed according to the heat exchange requirements.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0054] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0055] To address the technical problems of limited heat exchange area increase and inability to flexibly adjust the number of heat exchanger assemblies 2 in existing heat exchanger assembly 2 configurations, this application provides a mounting frame assembly 1, a modular heat exchanger, a heat exchange system, and a heat pump device. The mounting frame assembly 1 can be connected to the main body 111 and multiple support parts 112 in the mounting base 11 to form multiple mounting slots 113 for mounting heat exchanger assemblies 2. Multiple heat exchanger assemblies 2 can be stacked in the extension direction of the main body 111, which is beneficial to significantly or multiply the heat exchange area. Furthermore, the position and number of mounting slots 113 for mounting heat exchanger assemblies 2 can be selected according to heat exchange requirements, which is beneficial to flexibly adjust the number of heat exchanger assemblies 2 according to heat exchange requirements.

[0056] Please see Figures 1 to 14 The first aspect of this application provides a mounting bracket assembly 1, including a mounting base 11 and a connector 12. The mounting base 11 includes a main body 111 and a plurality of support parts 112. The support parts 112 are angularly connected to the main body 111, and the plurality of support parts 112 are arranged sequentially along the extending direction of the main body 111 to form a mounting groove 113 between adjacent support parts 112. A heat exchanger assembly 2 can be disposed in the mounting groove 113. Figure 1 , Figure 2 and Figure 7 As shown. Since multiple support portions 112 can be used to form multiple mounting grooves 113 in the extending direction of the main body portion 111, multiple heat exchanger assemblies 2 can be stacked in the extending direction of the main body portion 111, thereby achieving a significant increase in heat exchange area.

[0057] It is understandable that when the size of heat exchanger assembly 2 is fixed, the heat exchange area can be increased by n-1 times by stacking n heat exchanger assemblies 2. When the heat exchange area requirement is fixed, the structural size of a single heat exchanger assembly 2 can be reduced by stacking multiple heat exchanger assemblies 2, thereby reducing the overall footprint of multiple stacked heat exchanger assemblies 2.

[0058] The support part 112 is provided with a first flow hole 114, which allows airflow to enter between two adjacent heat exchanger components 2, thereby improving the airflow effect between the multiple heat exchanger components 2 stacked together, and thus ensuring the heat exchange effect of each heat exchanger component 2.

[0059] Both ends of the connector 12 are respectively connected to two oppositely arranged mounting bases 11. The two oppositely arranged mounting bases 11 can be used to connect to both ends of the heat exchanger assembly 2, forming a structurally stable mounting structure, such as... Figure 1 As shown.

[0060] An airflow channel 13 is formed between two opposing mounting bases 11, facilitating airflow to pass through the multi-layered, stacked heat exchanger assembly 2 and exchange heat with it. Figure 4 As shown ( Figure 4 The arrow in the image indicates the direction of airflow when the fan module 4, located above the heat exchanger assembly 2, performs suction.

[0061] It should be noted that this application allows for the stacking of multiple heat exchanger assemblies 2 via the mounting bracket assembly 1, connecting the mounting bracket assembly 1 and the multiple heat exchanger assemblies 2 into a single unit, forming a modular heat exchanger. This not only improves the heat exchange area and efficiency within the same space but also makes the stacked arrangement of multiple heat exchanger assemblies 2 more compact, significantly saving the floor space required for installing multiple heat exchanger assemblies 2.

[0062] It should be noted that the support portion 112 not only supports the heat exchanger assembly 2, but also serves as a spacer between two adjacent heat exchanger assemblies 2, creating a gas flow space between the two stacked heat exchanger assemblies 2. The dimensions of the support portion 112 can be set according to the weight of the heat exchanger assembly 2 and the spacing requirements. As long as it can provide stable support and space for the heat exchanger assembly 2, the purpose of this application can be achieved.

[0063] In some embodiments of this application, please refer to Figure 3 and Figure 4The support portion 112 is provided with a plurality of first flow holes 114, which are arranged sequentially along the extension direction of the support portion 112. Multiple airflow inlets can be formed in the extension direction of the support portion 112 so that the airflow can be dispersed and uniformly entered between two adjacent heat exchanger components 2. The airflow entering through the multiple airflow inlets interferes with and superimposes with each other in the gap between the heat exchanger components 2, and finally forms a three-dimensional uniform flow field on the surface of the heat exchanger components 2, so as to achieve uniform and sufficient heat exchange with the heat exchanger components 2.

[0064] It should be noted that the number and spacing of the first flow holes 114 can be designed according to the size of the heat exchanger assembly 2 and the heat exchange requirements. As long as the airflow can achieve uniform and sufficient heat exchange with the heat exchanger assembly 2 after passing through, the requirements of this application can be met.

[0065] As a specific embodiment of this application, please refer to Figure 2 Along the extension direction of the support 112, eight first flow holes 114 are evenly distributed in sequence, which facilitates airflow from both sides of the mounting bracket assembly 1 through the support 112 and into the space between two adjacent heat exchanger assemblies 2, which can greatly increase the air intake between two adjacent heat exchanger assemblies 2, thereby improving the heat exchange effect.

[0066] In the above embodiments, multiple support portions 112 can be disposed on the same side of the main body portion 111 or on opposite sides of the main body portion 111. As long as multiple heat exchanger components 2 can be stacked, the purpose of this application can be achieved.

[0067] Please refer to some preferred embodiments of this application. Figure 1 and Figure 2 Multiple support parts 112 are symmetrically arranged on both sides of the main body 111, which can make the gravity distribution of the mounting base 11 uniform and improve the structural stability of the mounting base 11 itself. Heat exchanger assemblies 2 can be installed on both sides of the mounting base 11, and the ends of the heat exchanger assemblies 2 are supported by the support parts 112, such as... Figure 1 As shown.

[0068] Multiple support portions 112 located on the same side of the main body 111 are arranged in parallel, which can be used to form multiple parallel mounting grooves 113, so that the spacing between the multiple heat exchanger assemblies 2 is kept consistent, which is conducive to achieving compact installation of the multiple heat exchanger assemblies 2, such as Figure 1 and Figure 2 As shown.

[0069] In the above embodiments, the support part 112 and the main body part 111 are connected at an angle, which can be a vertical connection or an inclined connection. In some preferred embodiments of this application, the support part 112 and the main body part 111 are connected at an inclination. Specifically, the support part 112 extends upward at an inclination to form a "fishbone" installation structure. This can reduce the floor space required for the installation of the heat exchanger assemblies 2 on both sides, and can also limit the heat exchanger assembly 2 through the support part 112 to prevent the heat exchanger assembly 2 from sliding out of the mounting groove 113 in an unconnected state. This is beneficial to improving the ease of assembly between the heat exchanger assembly 2 and the mounting bracket assembly 1.

[0070] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 13 The mounting base 11 includes a base frame portion 115 located at the bottom of the main body 111. A connector 12 is connected to the base frame portion 115 to form a frame structure at the bottom of the mounting frame assembly 1, so that the bottom of the mounting frame assembly 1 can be connected to the equipment frame 3 to achieve the fixed installation of the heat exchanger assembly 2 and the modular heat exchanger. The base frame portion 115 is provided with a second flow hole 116 to allow airflow to enter the airflow channel 13 through the second flow hole 116, thereby enhancing the heat exchange effect of the heat exchanger assembly 2 located at the bottom.

[0071] In some embodiments of this application, please refer to Figure 2 and Figure 3 The base frame 115 includes a base frame plate 1151 and a connecting plate 1152 connected in an L-shape. The base frame plate 1151 is used to connect with the main body 111, and the connecting plate 1152 is provided with a first connecting hole 1153, which can be used to fix the bottom of the base frame 11.

[0072] In some embodiments of this application, please refer to Figure 1 and Figure 2 The mounting frame 11 includes a lifting lug 117 located at the top of the main body 111. The lifting lug 117 can be lifted manually or by lifting equipment, thereby enabling the overall handling and transfer of the mounting frame assembly 1 and the heat exchanger assembly 2 (i.e., modular heat exchanger) mounted on the mounting frame assembly 1, which helps to reduce the overall installation and handling time of the equipment.

[0073] The lifting lug 117 is provided with a third flow hole 118. The third flow hole 118 can not only be used to realize the flow of air at the top of the heat exchanger assembly 2, but also facilitate the insertion of a hand or lifting claw, thereby realizing the overall handling of the mounting bracket assembly 1 and the heat exchanger assembly 2. Compared with conventional installation and handling methods, the installation and handling time of the modular heat exchanger of this application can be shortened by 20%-30%.

[0074] In the above embodiments, the shapes of the first flow hole 114, the second flow hole 116, and the third flow hole 118 can be set to circular, square, or polygonal as needed. In some preferred embodiments of this application, the third flow hole 118 is inverted trapezoidal in shape, which ensures that it has sufficient airflow area while facilitating the smooth insertion of a hand or lifting claw into the trapezoidal hole to grasp and transport the lifting lug 117.

[0075] In some embodiments of this application, please refer to Figure 1 and Figure 5 The connector 12 has base frame connecting plates 121 at both ends, which are used to fix and connect to two oppositely arranged mounting bases 11 (the connection method can be welding, bolt connection, etc.). The two base frame connecting plates 121 are connected by a reinforcing plate 123 to improve the structural strength of the connector 12. The bottom of the connector 12 is also provided with a bottom plate 122 that is connected to the reinforcing plate 123 in an L-shape, which can further enhance the rigidity and structural strength of the connector 12.

[0076] Please see Figures 1 to 14 The second aspect of this application provides a modular heat exchanger, including the mounting frame assembly 1 described in the above embodiments, and a heat exchanger assembly 2. The heat exchanger assembly 2 is connected to the mounting frame assembly 1 and disposed inside the airflow channel 13, forming a modular heat exchanger that is easy to install and transport. Within the same floor space, the overall heat exchange area of ​​the modular heat exchanger can be increased by stacking multiple heat exchanger assemblies 2 on the mounting frame assembly 1.

[0077] It should be noted that, since stacking multiple heat exchanger components 2 can significantly increase the heat exchange area, when the required heat exchange area is fixed, the volume of a single heat exchanger component 2 can be made sufficiently small, thereby reducing the structural dimensions of each modular heat exchanger. The number of modular heat exchangers installed in the heat pump equipment can be set according to the heat exchange requirements, such as... Figure 1 and Figure 13 As shown.

[0078] In some embodiments of this application, since the modular heat exchanger can be made small enough and easy to assemble, the production and processing cost of the modular heat exchanger in this application can be reduced by at least 30%-42% compared with the traditional V-type heat exchanger and G-type heat exchanger.

[0079] In some embodiments of this application, please refer to Figure 1There are multiple heat exchanger assemblies 2, each with a corresponding mounting slot 113, and the heat exchanger assemblies 2 are detachably connected to the mounting base 11. Multiple mounting slots 113 are arranged sequentially along the extension direction (i.e., the height direction) of the main body 111, allowing for the stacking of multiple heat exchanger assemblies 2. This enables adjustment of the heat exchange area without changing the footprint of the heat exchanger, thus meeting diverse user needs.

[0080] It should be noted that, since the heat exchanger assembly 2 and the mounting base 11 are detachably connected, the number of heat exchanger assemblies 2 installed on the mounting base assembly 1 can be flexibly adjusted according to the heat exchange requirements.

[0081] Specifically, when the heat exchange demand is large, a heat exchanger assembly 2 can be installed in each mounting slot 113 of the mounting bracket assembly 1 to obtain the maximum heat exchange area. When the heat exchange demand is small, multiple heat exchanger assemblies 2 can be installed at intervals. For example, heat exchanger assemblies 2 can be installed in the mounting slots 113 with odd-numbered layers (such as layers 1, 3, 5, 7, etc.) in the height direction, while the mounting slots 113 with even-numbered layers (such as layers 2, 4, 6, 8, etc.) in the height direction are left empty and no heat exchanger assemblies 2 are installed. This can increase the gas flow space and improve the heat exchange effect while meeting the heat exchange demand.

[0082] In some embodiments of this application, please refer to Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The heat exchanger assembly 2 includes a side plate 21, heat exchange fins 22, and heat exchange tubes 23. The heat exchange tubes 23 are respectively inserted into the heat exchange fins 22 and the side plate 21. A heat exchange medium (such as refrigerant) flows through the heat exchange tubes 23, allowing heat exchange with the air in the airflow channel 13. The heat exchange fins 22 increase the heat exchange area between the heat exchanger assembly 2 and the air. The heat exchange fins 22 and the heat exchange tubes 23 can directly contact each other for heat conduction, thereby improving the heat exchange efficiency of the heat exchange medium. The side plates 21 are located at both ends of the heat exchanger assembly 2 and are matched with the mounting grooves 113. They are used to connect the two ends of the heat exchanger assembly 2 to the two mounting bases 11, thereby enabling the installation of the heat exchanger assembly 2 on the mounting frame assembly 1.

[0083] In some embodiments of this application, please refer to Figure 1 When the main body 111 is connected to multiple support parts 112 in a "fishbone" installation structure, the heat exchanger assembly 2 is a block structure with a parallelogram cross-section. Two heat exchanger assemblies 2 set in the same layer of the mounting groove 113 of the mounting frame assembly 1 form a V-shaped heat exchanger unit, thereby realizing the superposition of multiple V-shaped heat exchanger units on the "fishbone" installation structure.

[0084] In some embodiments of this application, since the modular heat exchanger of this application adopts a "fishbone" installation structure, more heat exchanger components 2 can be arranged in the same space, which greatly increases the heat exchange area of ​​the modular heat exchanger. In the same space, the modular heat exchanger of this application can increase the heat exchange area by at least 38%-54% compared with the traditional V-type heat exchanger and G-type heat exchanger.

[0085] It should be noted that the shape of the side plate 21 can be matched with the mounting groove 113 on one side. In this case, the shape of the side plate 21 can be a parallelogram, such as... Figure 8 , Figure 10 and Figure 11 As shown, it can also be simultaneously matched with the mounting slots 113 on the left and right sides of the mounting base 11. In this case, the shape of the side plate 21 can be V-shaped, such as... Figure 1 , Figure 6 and Figure 7 As shown, the installation of two heat exchanger assemblies 2 on both sides of the main body 111 can be achieved simultaneously through the side plate 21, which simplifies the assembly process.

[0086] Please refer to some preferred embodiments of this application. Figure 6 and Figure 9 The side plate 21 includes a V-shaped plate body 211 and a flange 212 provided along the edge of the V-shaped plate body 211. The V-shaped plate body 211 is provided with a plurality of mounting holes 214, which can be used to synchronously connect with the heat exchange tubes 23 in the two heat exchanger assemblies 2 on both sides of the main body 111. The flange 212 is provided at the edge of the V-shaped plate body 211, which can improve the torsional stiffness of the V-shaped plate body 211 without interfering with the connection between the V-shaped plate body 211 and the heat exchange tubes 23, thereby improving the structural strength and reliability of the side plate 21.

[0087] The V-shaped plate 211 is provided with a connecting part 213 for connecting to the mounting base 11. This part can be used to connect to the second connecting holes 119 provided on the main body 111 and the support part 112, respectively, thereby simultaneously enabling the installation of two heat exchanger assemblies 2 on both sides of the main body 111. Figure 3 and Figure 7 As shown.

[0088] In some embodiments of this application, please refer to Figure 8 and Figure 9 There are multiple heat exchange tubes 23, and there is a preset gap between any two adjacent heat exchange tubes 23. The preset gap is connected to the airflow channel 13 so that the air in the airflow channel 13 can enter the preset gap between the heat exchange tubes 23 and exchange heat synchronously with the multiple heat exchange tubes 23.

[0089] Multiple heat exchange fins 22 are provided on the heat exchange tube 23. The multiple heat exchange fins 22 are arranged sequentially along the length of the heat exchange tube 23, so that the multiple heat exchange tubes 23 and the multiple heat exchange fins 22 can form an interlocking connection structure. The airflow can flow in a tortuous manner through the gap formed by the connection between the heat exchange tubes 23 and the heat exchange fins 22, which is beneficial to prolonging the flow time of the airflow in the heat exchanger assembly 2 and realizing sufficient heat exchange between the heat exchanger assembly 2 and the air.

[0090] It should be noted that this application Figure 1 , Figure 2 and Figure 13 The heat exchanger assembly 2 in the diagram is a simplified schematic diagram and does not show the airflow gap formed after multiple heat exchange tubes 23 and multiple heat exchange fins 22 are interwoven and connected. It does not constitute an improper limitation of this application.

[0091] In some embodiments of this application, when the heat exchange area requirement is certain, the volume of a single heat exchanger assembly 2 can be set to be small enough. At this time, the length of a single heat exchange tube 23 can also be set short enough. For example, the length of the heat exchange tube 23 in a conventional radiator is usually 1800mm-2400mm, while the length of the heat exchange tube 23 in this application can be set to 700mm, but it can still meet the heat exchange requirements.

[0092] In some embodiments of this application, since the heat exchange tube 23 of this application can be a shorter and straighter copper tube, the flow resistance of the refrigerant is reduced, so that the flow resistance of the modular heat exchanger of this application can be reduced by at least 50%-60% compared with the V-type heat exchanger and the G-type heat exchanger.

[0093] In some embodiments of this application, please refer to Figure 9 , Figure 10 , Figure 11 and Figure 12 The heat exchanger assembly 2 also includes multiple distribution pipes 24 and multiple U-shaped pipes 25. The distribution pipes 24 can be used to simultaneously input the heat exchange medium into multiple heat exchange tubes 23, and the U-shaped pipes 25 can be used to connect two heat exchange tubes 23, thereby realizing the reverse flow of the heat exchange medium.

[0094] In some embodiments of this application, please refer to Figure 9 , Figure 10 and Figure 11 Multiple liquid distribution pipes 24 are all located at the same end of the heat exchanger assembly 2 to facilitate the layout of the heat exchange medium input pipeline. Each liquid distribution pipe 24 includes a pipe body 242 with multiple interfaces, one of which is a refrigerant inlet 241. The other interfaces, except for the refrigerant inlet 241, are used to connect to the input end of the heat exchange tube 23, which can realize one inlet and multiple outlets of the heat exchange medium. The one inlet and multiple outlets design reduces the number of capillary tubes connected to the heat exchange medium inlet, thereby saving material costs.

[0095] As a specific embodiment of this application, please refer to Figure 9 , Figure 10 and Figure 11 The liquid distribution pipe 24 is a three-way pipe with three ports. One port is a refrigerant inlet 241, and the other two ports are connected to two heat exchange tubes 23 respectively. Multiple liquid distribution pipes 24 are located in the middle of the right end of the heat exchanger assembly 2. Each liquid distribution pipe 24 has a U-shaped pipe 25 on both sides to achieve communication between two adjacent heat exchange tubes 23. Multiple U-shaped pipes 25 and multiple refrigerant outlets 26 are provided at the left end of the heat exchanger assembly 2, which can form multiple heat exchange working fluid flow channels, thereby shortening the total length of each heat exchange working fluid flow channel and reducing the flow resistance of the heat exchange working fluid.

[0096] Specifically, 'a' represents the inlet of the separator 24, 'b' and 'b' represent the two ends of one heat exchange tube 23, 'c' and 'c' represent the two ends of another heat exchange tube 23, and so on. 'bb', 'cc', 'dd', 'ee', 'ff', and 'gg' represent six different heat exchange tubes 23. When the heat exchange medium flows in from point 'a', two heat exchange medium flow channels are formed. One channel flows sequentially through the three heat exchange tubes 23: 'bb', 'dd', and 'ff'. The other channel flows sequentially through the three heat exchange tubes 23: 'cc', 'ee', and 'gg'. The flow direction is as follows: Figure 12 As shown, by referring to the liquid separator 24, heat exchange tube 23 and U-shaped tube 25 Figure 9 and Figure 10 The connection method allows the total length of each heat exchange medium flow channel to be approximately the sum of the lengths of three straight copper tubes (i.e., heat exchange tube 23), which can shorten the total length of each heat exchange medium flow channel and reduce the flow resistance of the heat exchange medium.

[0097] Please see Figures 1 to 14 The third aspect of this application provides a heat exchange system, including the modular heat exchanger described in the above embodiments, and a refrigerant circulation loop connected to the modular heat exchanger for inputting refrigerant into the heat exchanger assembly 2 so as to exchange heat with the air in the airflow channel 13, thereby realizing the phase change of the refrigerant inside the heat exchange tube 23.

[0098] It should be noted that this heat exchange system can be applied to air conditioning units or heat pump equipment. The number of modular heat exchangers in the heat exchange system can be adjusted according to the heat exchange requirements of the system. It has the advantages of small footprint, large heat exchange area and easy installation and transportation.

[0099] Please see Figures 1 to 14The fourth aspect of this application provides a heat pump device. The heat exchange system described in the above embodiment further includes a device frame 3. The device frame 3 includes a first mounting area 31 and a second mounting area 32 arranged sequentially along the height direction. The first mounting area 31 is used to install a fan module 4, and the second mounting area 32 is used to install a modular heat exchanger. The fan module 4 drives the gas flow in the airflow channel 13, thereby achieving efficient heat exchange between the airflow and the heat exchanger assembly 2 in the modular heat exchanger to meet the heat exchange requirements of the heat pump device. Figure 4 and Figure 13 As shown.

[0100] It should be noted that when the fan module 4 is placed above the modular heat exchanger, the fan module 4 can discharge air downwards to achieve airflow drive and heat exchange through positive pressure blowing, or it can discharge air upwards to achieve airflow drive and heat exchange through negative pressure suction, both of which can achieve the purpose of this application.

[0101] As a specific embodiment of this application, Figure 4 This illustrates the flow trend of air around the modular heat exchanger when the fan module 4 drives the airflow through negative pressure suction. Air can enter the modular heat exchanger from all sides and be discharged upwards by the fan module 4 after heat exchange.

[0102] It should be noted that the number of fans in fan module 4 can be set according to the floor space and heat exchange efficiency of the modular heat exchanger. When only some modular heat exchangers are running, the number of fans can be reduced accordingly, and only the fans corresponding to the positions of the running modular heat exchangers can be turned on, thereby achieving the purpose of high efficiency and energy saving.

[0103] In some embodiments of this application, please refer to Figure 13 The number of modular heat exchangers is multiple, and the multiple modular heat exchangers are evenly installed in the second installation area 32 so that the fan module 4 can drive the airflow to achieve uniform heat exchange with the multiple modular heat exchangers.

[0104] The bottom of the second installation area 32 is equipped with a water receiving tray 5 and a drainage structure 6, which can collect and discharge the condensate generated by the modular heat exchanger during the heat exchange process, and prevent the condensate from flowing arbitrarily at the bottom of the modular heat exchanger, which could lead to freezing and ice buildup at low temperatures.

[0105] In some embodiments of this application, please refer to Figure 13 The equipment frame 3 also includes a third installation area 33, which can be used to install other components of the heat exchange system, such as compressors, vapor-liquid separators, heat exchangers, four-way reversing valves, liquid storage tanks, and refrigerant connection piping components, so as to realize the regional setting of the heat exchange system in the equipment frame 3.

[0106] The first installation area 31, the second installation area 32, and the third installation area 33 are arranged sequentially from top to bottom. The drainage structure 6 includes a drain pipe 61 extending outward toward the third installation area 33 to prevent condensate from being discharged into the third installation area 33, thereby preventing the components in the third installation area 33 from being corroded and rusted by the discharged water flow, which helps to ensure the service life of the components in the third installation area 33.

[0107] In some embodiments of this application, please refer to Figure 13 and Figure 14 The water receiving tray 5 includes a tray body 51 and a water-blocking edge 52 arranged around the circumference of the tray body 51, so that the water receiving tray 5 has a certain water storage capacity and prevents condensate from overflowing from the water receiving tray 5. The base frame part 115 of the mounting base 11 is set on the tray body 51 and is fixedly connected to the tray body 51 through the first connecting hole 1153. The bottom plate 122 of the connector 12 is in contact with the surface of the tray body 51, which can improve the connection stability between the mounting frame assembly 1 and the water receiving tray 5, thereby improving the installation stability of the modular heat exchanger in the water receiving tray 5.

[0108] It should be noted that when the heat exchanger assembly 2 is tilted on the "fishbone" mounting structure, since the heat exchanger assembly 2 is also tilted after being connected to the support part 112, it is beneficial for the condensate on the surface of the heat exchanger assembly 2 to flow down, so that the condensate can be accurately dripped into the water receiving pan 5, thereby facilitating the collection of the condensate generated on the surface of the heat exchanger assembly 2 by the water receiving pan 5.

[0109] In some embodiments of this application, please refer to Figure 13 and Figure 14 The drainage structure 6 includes multiple water collection troughs 62 formed in the plate body 51. The bottom of the water collection trough 62 is provided with a drain hole 63 that communicates with the drain pipe 61, so as to drain the water accumulated in the water receiving plate 5 and the water collection trough 62.

[0110] As a specific embodiment of this application, please refer to Figure 13 and Figure 14 Multiple modular heat exchangers are arranged in a matrix in the water receiving pan 5. Each row or column of modular heat exchangers is provided with a water collection tank 62 extending along the arrangement direction. The condensate on the surface of the inclined heat exchanger assembly 2 flows downward and can accurately drip into the water collection tank 62. Both ends of the water collection tank 62 are provided with drain holes 63, and each drain hole 63 is provided with a corresponding connected drain pipe 61, which can improve the drainage efficiency of the drainage structure 6.

[0111] In some embodiments of this application, the heat exchange system includes a compressor and a fluid heat exchanger. Both the compressor and the fluid heat exchanger are connected to a modular heat exchanger via a refrigerant circulation loop. The fluid heat exchanger can be used to achieve heat exchange between the refrigerant and the target fluid (such as water, oil, etc.), thereby heating the target fluid flowing inside the fluid heat exchanger. In this case, the fluid heat exchanger is the condensation module in the heat exchange system, and the modular heat exchanger is the evaporation module in the heat exchange system.

[0112] In some embodiments of this application, the heat pump equipment can be used to produce hot water. Specifically, the fluid heat exchanger can be a shell-and-tube heat exchanger or a similar heat exchanger capable of exchanging heat between hot and cold fluids. When the compressor compresses the refrigerant, its pressure and temperature rise rapidly. The high-temperature, high-pressure refrigerant flows into the fluid heat exchanger and exchanges heat with the target fluid (i.e., water) flowing inside, thus heating the water and supplying hot water. The condensed refrigerant flowing out of the fluid heat exchanger flows into the expansion valve for throttling and pressure reduction, and then flows into the modular heat exchanger. The heat exchanger assembly 2 absorbs heat from the air in the airflow channel. The refrigerant inside the heat exchange tube 23 exchanges heat with the air and becomes a low-temperature, low-pressure gaseous refrigerant, which then flows back to the compressor for the next refrigerant cycle.

[0113] It should be noted that when users do not require the heat pump equipment to produce large quantities of hot water, only a portion of the modular heat exchangers can be operated, which can correspondingly reduce the number of fans in operation, thereby achieving high efficiency and energy saving. If the heat exchange capacity of the modular heat exchangers is insufficient during the operation of the heat pump equipment, the number of fans can be adjusted, increasing the number of fans operating in fan module 4, thereby enhancing the heat exchange between the refrigerant and the air.

[0114] It should be noted that this application sets the evaporator in the heat pump equipment that generates hot water as one or more modular heat exchangers. This not only greatly saves the floor space required for the evaporator of large heat pump equipment, but also allows the heat exchanger component 2 to be flexibly configured according to different application scenarios, meeting diverse user needs. Furthermore, within the same space, the modular heat exchanger of this application has a larger heat exchange area and higher heat exchange efficiency.

[0115] Please see Figures 1 to 14 In some embodiments of this application, the assembly process of the modular heat exchanger described above is as follows:

[0116] Step 1: Assemble multiple heat exchange tubes 23 and multiple heat exchange fins 22 into a whole;

[0117] Step 2: Fix multiple side plates 21 onto the mounting base 11 on both sides of the mounting frame assembly 1 via the connecting part 213 and the second connecting hole 119;

[0118] Step 3: Insert one end of the multiple heat exchange tubes 23 into the side plate 21 on one side of the mounting bracket assembly 1, and then adjust the installation position by sliding the heat exchange tubes 23 so that the other end of the multiple heat exchange tubes 23 can be inserted into the side plate 21 on the other side of the mounting bracket assembly 1.

[0119] Step 4: Install multiple liquid distribution pipes 24 and multiple U-shaped pipes 25 at both ends of the heat exchanger assembly 2 to connect the heat exchange medium flow channels inside the heat exchanger assembly 2, thus completing the assembly of the modular heat exchanger.
