Abstract
Description
Technical Field
[0001] The present application relates to the field of temperature control technology, and in particular to a heat exchanger module and a control cabinet. Background Art
[0002] In the field of temperature control, finned tube heat exchanger is a widely used heat exchange equipment.
[0003] In existing systems, the fin-tube heat exchanger of an environmental control cabinet is integrally fixed to the interior of the cabinet. When the equipment within the cabinet generates heat, the fin-tube heat exchanger removes the heat through the circulation of an internal cooling fluid (such as water or refrigerant), thereby reducing the temperature within the cabinet. However, in the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:
[0004] First, since the entire fin-tube heat exchanger needs to be fixed inside the box, complex tools and tedious procedures are required for installation, making assembly difficult. In addition, maintenance requires disassembly of the box shell, which is complicated and takes a lot of time and effort.
[0005] Secondly, during the overall fixed installation process, the design and implementation of the sealing structure is relatively difficult, and the existing fin-tube heat exchanger has no sealing structure, so the sealing performance is difficult to ensure, which will affect the heat exchange efficiency of the heat exchanger and reduce the performance of the entire control cabinet.
[0006] Therefore, how to achieve a solution that is both convenient and quick while ensuring a good sealing effect during the installation process of the fin-tube heat exchanger has become a technical problem that those skilled in the art currently need to solve. Summary of the Invention
[0007] The purpose of this application is to provide a heat exchanger module and control cabinet that can simplify the installation process and ensure sealing performance.
[0008] To achieve the above objectives, the present application provides a heat exchanger module, comprising:
[0009] The outer shell is provided with a mounting opening;
[0010] The heat exchanger module comprises a heat exchanger body, which is installed into an outer shell through an installation opening and forms a sealing structure for sealing the installation opening.
[0011] In some embodiments, the outer shell is also provided with a fixed sealing surface located outside the installation port, and the heat exchanger module also includes a fixed sealing shell provided on the heat exchanger body. The fixed sealing shell is located on the outside of the outer shell, and the fixed sealing shell is connected with the fixed sealing surface to form a sealing structure.
[0012] In some embodiments, the fixed sealed shell includes an annular plate body and a partition plate provided at a first end of the annular plate body, and the first end of the heat exchanger body is fitted through the partition plate and accommodated in the annular plate body;
[0013] The heat exchanger module also includes a water inlet pipe and a water outlet pipe connected to the heat exchanger body. The water inlet pipe and the water outlet pipe are both located outside the partition, and both pass through the annular plate body and the outer shell.
[0014] In some embodiments, the fixed sealing shell also includes a fixed sealing flange, which is arranged at the second end of the annular plate body. A first elastic sealing member is provided between the fixed sealing flange and the fixed sealing surface, and the fixed sealing flange and the fixed sealing surface are circumferentially locked by a detachable connecting member.
[0015] In some embodiments, the heat exchanger module further includes a heat exchanger cover plate, a second elastic seal is provided between the heat exchanger cover plate and the fixed sealing flange, and the heat exchanger cover plate and the fixed sealing flange are circumferentially locked by a detachable connector.
[0016] In some embodiments, the fixed sealing surface is provided with a first avoidance groove and a second avoidance groove, the water inlet pipe and the water outlet pipe are respectively placed in the first avoidance groove and the second avoidance groove, and a third elastic seal is provided between the water inlet pipe and the first avoidance groove, and between the water outlet pipe and the second avoidance groove.
[0017] In some embodiments, the heat exchanger module further comprises:
[0018] A fixed protective shell is fixed to a side of the heat exchanger body away from the fixed sealing shell and is used to accommodate the second end of the heat exchanger body;
[0019] Two guard plates are arranged between the fixed protective shell and the fixed sealing shell to protect the heat exchanger body.
[0020] In some embodiments, the outer shell is provided with a guide rail located inside the installation opening, and the heat exchanger module is slidably engaged with the guide rail so that the heat exchanger module slides into the outer shell along the guide rail.

[0023] In contrast to the above background technology, the heat exchanger module provided in the embodiments of the present application includes an outer shell and a heat exchanger module. The outer shell has a mounting opening, and the heat exchanger module includes a heat exchanger body, which is installed into the outer shell through the mounting opening, forming a sealing structure for sealing the mounting opening.
[0024] The heat exchanger module thus configured has the following beneficial effects:

[0026] Secondly, when the heat exchanger body is installed into the installation port, the sealing structure formed can seal the installation port. This establishes a reliable sealing structure while the heat exchanger body is inserted and installed, reducing the risk of gas leakage inside the outer shell, ensuring the stability of the airflow organization inside the outer shell, and ensuring that the heat exchange inside the heat exchanger can be carried out efficiently in a closed environment with good sealing performance, thereby improving the heat exchange efficiency of the heat exchanger and providing more reliable protection for the entire control cabinet.

[0062] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0063] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0064] The heat exchanger module provided in the embodiment of the present application includes an outer shell 10 and a heat exchanger module 20. The heat exchanger module can be a fin-tube heat exchanger module. Accordingly, the heat exchanger module 20 is a fin-tube heat exchanger module, which is installed in the outer shell 10 in an inserting manner.
[0065] Specifically, the outer shell 10 is provided with an installation opening 11 , and the heat exchanger module 20 includes a heat exchanger body 21 . The heat exchanger body 21 is installed into the outer shell 10 through the installation opening 11 and forms a sealing structure for sealing the installation opening 11 .
[0066] Set it up like this:
[0067] On the one hand, the heat exchanger module adopts an insert-type installation method, and the heat exchanger body 21 is installed into the outer shell 10 through the installation port 11. This insert-type design greatly simplifies the installation steps, so that the installation process does not require complex tools and tedious procedures, and the installer can complete the installation task quickly. In addition, when the heat exchanger needs to be repaired or replaced, it is only necessary to separate the heat exchanger body 21 from the outer shell 10 and remove the heat exchanger body 21 from the installation port 11. There is no need to disassemble the outer shell 10 on a large scale, which improves work efficiency and reduces disassembly and assembly costs.
[0068] On the other hand, when the heat exchanger body 21 is installed into the installation port 11, the formed sealing structure can seal the installation port 11. This establishes a reliable sealing structure while the heat exchanger is inserted and installed, reducing the risk of gas leakage inside the outer shell 10, ensuring the stability of the airflow organization inside the outer shell 10, and ensuring that the heat exchange inside the heat exchanger can be carried out efficiently in a closed environment with good sealing performance, thereby improving the heat exchange efficiency of the heat exchanger and providing more reliable protection for the entire control cabinet.
[0069] See also Figure 1 and Figure 2 In the first heat exchanger module, the outer shell 10 is further provided with a fixed sealing surface 12 located outside the installation opening 11; the heat exchanger module 20 also includes a fixed sealing shell 22 provided on the heat exchanger body 21. The heat exchanger body 21 is installed into the outer shell 10 through the installation opening 11. The fixed sealing shell 22 is located on the outside of the outer shell 10. After the fixed sealing shell 22 is docked with the fixed sealing surface 12, a sealing structure is formed for sealing the installation opening 11.
[0070] The connection methods between the fixed sealing shell 22 and the fixed sealing surface 12 include, but are not limited to, snap connection, magnetic connection, flange surface connection, and the like.
[0071] like Figure 1 As shown, during installation, simply align the rear end of the heat exchanger body 21 with the mounting opening 11 of the outer shell 10 and push the heat exchanger body 21 horizontally to the left. When the fixed sealing shell 22 mates with the fixed sealing surface 12, a sealed connection is achieved. To disassemble, simply unlock the fixed sealing shell 22 from the fixed sealing surface 12 and pull the heat exchanger body 21 horizontally to the right.
[0072] Please also refer to Figure 3 and Figure 4 The fixed sealing shell 22 includes an annular plate body 221 and a partition plate 222 provided at a first end of the annular plate body 221 . The first end of the heat exchanger body 21 is fitted with the partition plate 222 and accommodated in the annular plate body 221 .
[0073] It can be seen that the annular plate 221 and the partition 222 are combined to form a box structure. The first end of the heat exchanger body 21 passes through the partition 222 but does not extend out of the annular plate 221, which can protect the first end of the heat exchanger body 21.
[0074] In addition, the heat exchanger module 20 also includes a water inlet pipe 23 and a water outlet pipe 24 connected to the heat exchanger body 21. The water inlet pipe 23 is used to input cooling fluid (such as water or refrigerant) into the heat exchanger body 21, and the water outlet pipe 24 is used to guide the cooling fluid undergoing heat exchange out of the heat exchanger body 21, so that the cooling fluid circulates in the heat exchanger body 21 to take away the heat, thereby reducing the temperature inside the temperature control cabinet where the heat exchanger module is located.
[0075] The water inlet pipe 23 and the water outlet pipe 24 are both located in the outer area of the partition 222 (the outer area refers to the outer area of the partition 222). Figure 3 As shown in the right area), the water inlet pipe 23 and the water outlet pipe 24 both pass through the annular plate 221 and the outer shell 10 in a direction perpendicular to the direction in which the heat exchanger body 21 is installed into the outer shell 10.
[0076] Referring to the arrangement of the fixed sealed shell 22 , the heat exchanger module 20 further includes a fixed protective shell 29 , which is fixed to a side of the heat exchanger body 21 away from the fixed sealed shell 22 , and is used to accommodate the second end of the heat exchanger body 21 .
[0077] The fixed protective shell 29 is also a box structure. The second end of the heat exchanger body 21 passes through the bottom plate of the fixed protective shell 29 but does not extend out of the fixed protective shell 29. In this way, the fixed protective shell 29 can protect the second end of the heat exchanger body 21.
[0078] In addition, the heat exchanger module 20 also includes two guard plates 210, which are arranged between the fixed protective shell 29 and the fixed sealing shell 22, and the two guard plates 210 are respectively arranged on the upper and lower sides of the heat exchanger body 21. The two guard plates 210 are used to protect the fin part of the heat exchanger body 21.
[0079] Please also refer to Figure 5Using this configuration, the heat exchanger module 20 is divided into a front-end pipe protection zone 202, a flow zone 201, and a rear-end pipe protection zone 203. The flow zone 201 is located between the front-end pipe protection zone 202 and the rear-end pipe protection zone 203. Both the housing structures housing the front-end pipe protection zone 202 and the rear-end pipe protection zone 203 are box-shaped. The front-end pipes (the first end of the heat exchanger body 21) of the heat exchanger body 21 are protected by a fixed, box-shaped sealing shell 22, while the rear-end pipes (the second end of the heat exchanger body 21) are protected by a fixed, box-shaped protective shell 29. The fins in the flow zone 201 are protected by two protective plates 210. The heat exchanger module is designed in a regular rectangular shape for easy installation.
[0080] It should be noted that the so-called flow area 201 mainly refers to the area where the fins of the heat exchanger body 21 are located. The cooling fluid circulating inside the heat exchanger body 21 dissipates heat through the fins outside the heat exchanger body 21. Not only that, a fan module can also be set on the periphery of the heat exchanger body 21, and the fan module can be used to blow air, so as to take away the heat on the fins through air cooling, thereby improving the heat exchange efficiency of the heat exchanger module.
[0081] It is understandable that conventional fin-tube heat exchange modules employ a design where the inlet and outlet tube ends are not separated from the fin flow area, which may result in a poor seal between the inlet and outlet tube ends and the fin flow area (for example, under high-temperature and high-pressure heat exchange conditions, fluid can easily leak from the connection between the inlet and outlet tube ends and the fin flow area). In contrast, the embodiments of the present application isolate the inlet and outlet tube ends from the fin flow area via a partition 222 fixed to the sealing shell 22. After isolation by partition 222, partition 222 can serve as a sealing structure, effectively preventing fluid leakage between the inlet and outlet tube ends and the fin flow area, thereby improving the sealing performance of the entire heat exchanger module and ensuring the stability and safety of the heat exchange process.
[0082] In addition to improving sealing, the design of isolating the inlet and outlet pipe ends from the fin flow area through the partition 222 also facilitates the installation and maintenance of the heat exchanger module 20. Specifically, during assembly, the assembler can first install the inlet and outlet pipe ends and other components in the corresponding areas of the fixed sealing shell 22, and then insert the entire assembly into the outer shell 10. This drawer-type structure makes the assembly sequence and position of each component clearer, greatly simplifying the assembly process and achieving the effect of convenient installation. Similarly, in terms of maintenance, when the inlet and outlet pipe ends or the components in the fin flow area need to be inspected, replaced, or cleaned, the partition 222 can be used to isolate them, allowing maintenance personnel to easily remove the parts that need maintenance from the outside for maintenance.
[0083] As can be seen from the above, the heat exchanger module mainly consists of the heat exchanger body 21, the fixed sealing shell 22, the fixed protective shell 29, and two protective plates 210. The heat exchanger body 21 includes fins 211, a first U-tube 212, and a second U-tube 213. The first U-tube 212 is a short U-tube, and the second U-tube 213 is a long U-tube. During assembly, the long U-tube sequentially connects the fixed protective shell 29, fins 211, and fixed sealing shell 22 in series. The long U-tube is then interference-fitted with the fixed protective shell 29, fins 211, and fixed sealing shell 22 through mechanical or hydraulic expansion. Finally, the long U-tubes are welded together through short U-tubes to form a channel with water inlet and outlet. When there are multiple water inlet and outlet flow paths, the heat exchanger module 20 also includes an inlet fluted pipe 231 and an outlet fluted pipe 241. The inlet pipe 23 and the outlet pipe 24 are respectively connected to the inlet fluted pipe 231 and the outlet fluted pipe 241. In this way, the inlet pipe 23 and the outlet pipe 24 can be merged into one water inlet and one water outlet through the inlet fluted pipe 231 and the outlet fluted pipe 241 respectively.
[0084] In order to facilitate the locking and sealing of the fixed sealing shell 22, the fixed sealing shell 22 also includes a fixed sealing flange 223, which is arranged at the second end of the annular plate body 221 (the fixed sealing shell 22 as a whole can be a T-shaped structure), and a first elastic sealing member 25 is provided between the fixed sealing flange 223 and the fixed sealing surface 12, and the fixed sealing flange 223 and the fixed sealing surface 12 are circumferentially locked by a detachable connecting member 28.
[0085] It can be understood that the above-mentioned fixed sealing flange 223 can be regarded as a first flange surface formed by being flipped outward and set on the fixed sealing shell 22, and the first flange surface has a front end flange wall and a rear end flange wall. The fixed sealing surface 12 can be regarded as a second flange surface formed by being flipped outward and set at the mounting port 11 of the outer shell 10, wherein the rear end flange wall and the fixed sealing surface 12 form a sealing structure through the first elastic seal 25, thereby realizing spatial isolation between the flow area 201 and the external take-over area of the module.
[0086] During installation, a groove can be set on the fixed sealing flange 223 and / or the fixed sealing surface 12. The first elastic seal 25 is specifically an elastic rubber strip. The first elastic seal 25 is installed in the groove and protrudes from the groove. The pressure generated when the fixed sealing flange 223 and the fixed sealing surface 12 are circumferentially locked through the detachable connector 28 is used to elastically deform the first elastic seal 25, thereby achieving the effect of sealing the gap between the fixed sealing flange 223 and the fixed sealing surface 12.
[0087] Please also refer to Figure 6 and Figure 7In order to further improve the sealing performance of the module after installation, the heat exchanger module 20 also includes a heat exchanger cover 26. A second elastic seal 27 is provided between the heat exchanger cover 26 and the fixed sealing flange 223, and the heat exchanger cover 26 and the fixed sealing flange 223 are circumferentially locked by a detachable connector 28.
[0088] As will be understood, due to the poor sealing performance of the U-tube holes in the fixed sealing shell 22, a heat exchanger cover 26 is designed. A second elastic seal 27 (also known as a cover seal strip) is affixed to the heat exchanger cover 26. The cover 26 also includes holes corresponding to the mounting holes in the fixed sealing surface 12 and the fixed sealing shell 22. Removable connectors 28 (specifically, fixing screws) create an interaction force between the heat exchanger cover 26, the fixed sealing surface 12, and the fixed sealing shell 22, pressing the second elastic seal 27 against the first elastic seal 25. The assembly method for the second elastic seal 27 can be similar to that for the first elastic seal 25.
[0089] In some embodiments, a first avoidance groove 121 and a second avoidance groove 122 are respectively provided at positions corresponding to the water inlet pipe 23 and the water outlet pipe 24 on the fixed sealing surface 12, and the water inlet pipe 23 and the water outlet pipe 24 are respectively placed in the first avoidance groove 121 and the second avoidance groove 122, and a third elastic sealing member is provided between the water inlet pipe 23 and the first avoidance groove 121, and between the water outlet pipe 24 and the second avoidance groove 122.
[0090] During assembly, the rear-end pipe protection zone 203 of the heat exchanger module 20 is first inserted into the installation opening 11. Then, a thrust is applied to the front-end pipe protection zone 202 to fully push the heat exchanger module 20 into the interior of the outer shell 10. When pushed to the bottom, the fixed sealing shell 22 presses against the first elastic seal 25. Simultaneously, the water inlet pipe 23 and the water outlet pipe 24 are pressed into the first avoidance groove 121 and the second avoidance groove 122, respectively, forming a sealed structure through the third elastic seal.
[0091] In order to facilitate assembly, the positions of the first elastic sealing member 25 corresponding to the water inlet pipe 23 and the water outlet pipe 24 can be respectively provided with avoidance shapes or direct openings.
[0092] In some embodiments, the outer shell 10 is provided with a guide rail 13 located inside the installation opening 11 , and the heat exchanger module 20 slidably cooperates with the guide rail 13 so that the heat exchanger module 20 slides into the outer shell 10 along the guide rail 13 .
[0093] For example, a slider or a support pulley that slides with the guide rail 13 can be provided on the heat exchanger module 20. Through the sliding cooperation between the slider or the support pulley and the guide rail 13, the heat exchanger module 20 can be flexibly and conveniently slid into the outer shell 10 to avoid jamming, and has the function of quick assembly and ensuring that the gas in the outer shell 10 does not leak.
[0094] As can be seen from the above, the heat exchanger module 20 is designed to have a regular rectangular shape. An installation opening 11 (or insertion opening) is provided on the surface of the outer shell 10 where it is to be installed. A guide rail 13 is designed inside the outer shell 10, flush with the insertion opening. The installation opening 11 is provided with an outward-facing fixed sealing surface 12, which can be fitted with a nut. A first elastic seal 25 can also be attached to the fixed sealing surface 12. During assembly, the rear-end pipe protection zone 203 of the heat exchanger module 20 is first inserted into the installation opening 11. A thrust is then applied to the front-end pipe protection zone 202 to fully push the heat exchanger module 20 into the interior of the outer shell 10. When pushed to the bottom, the fixed sealing shell 22 presses against the first elastic seal 25, while the water inlet pipe 23 and the water outlet pipe 24 are respectively pressed into the first and second avoidance grooves 121 and 122, forming a sealed structure with the third elastic seal.
[0095] In some embodiments, a guide plate is provided on the inner wall of the outer shell 10 , and the guide plate extends to the air inlet side of the heat exchanger body 21 , and the guide angle of the guide plate is 30-60°.
[0096] It should be noted that the guide plate extends to the air inlet side of the heat exchanger body 21 and is tilted at an angle of 30°-60°, guiding the airflow to evenly cover the flow area 201 of the heat exchanger module 20 (i.e., the area where the fins 211 are located). Specifically, in traditional designs, direct fan blowing into the heat exchanger module 20 can easily lead to excessive wind speeds in the center and insufficient flow speeds at the edges, creating heat exchange blind spots. The guide plate diverts the airflow at an angle, allowing it to diffuse along the fin surface, improving the utilization of the effective heat exchange area. At the same time, the 30°-60° inclination angle promotes moderate vortex formation in the airflow, disrupting the thermal boundary layer (temperature boundary layer) and enhancing the convective heat transfer coefficient. Research has shown that this type of disturbance can increase air-side heat exchange efficiency by 15%–25%.
[0097] Of course, the guide angle of the guide plate is not limited to the above range, and it can be appropriately adjusted according to the flow area 201 of the heat exchanger module 20.
[0098] In addition, the guide plate can also smooth the transition of airflow, reduce the pressure loss caused by sudden expansion of the inlet, and use more energy for heat exchange rather than overcoming resistance.
[0099] In some embodiments, a liquid collecting tank is provided at the bottom of the outer shell 10 , and the liquid collecting tank is connected to an external pipeline through a drain valve.
[0100] The liquid collection tank is located at the lowest point of the bottom of the outer shell 10, collecting liquids from accidental dripping, leakage from device interfaces, or cleaning residues through gravity, preventing the liquid from spreading within the device. Furthermore, the liquid collection tank is connected to an external pipeline or collection container via a drain valve, directing waste liquid to a treatment system, avoiding direct discharge into the environment or the device interior, thus complying with environmental protection requirements.
[0101] Please also refer to Figures 8 to 10 In the second heat exchanger module, there are two fixed sealing flanges 223 on the heat exchanger body 21, and the two fixed sealing flanges 223 are arranged at intervals along the insertion direction of the heat exchanger body 21. One of the fixed sealing flanges 223 directly contacts the outer wall of the outer shell 10 (the outer wall of the outer shell 10 is provided with a fixed sealing surface 12 located outside the installation opening 11), thereby achieving the purpose of sealing the installation opening 11 after forming a sealing structure.
[0102] Furthermore, to achieve a sealing effect, a first elastic seal 25 may be added between the fixed sealing flange 223 and the outer shell 10, and the fixed sealing flange 223 and the outer shell 10 are circumferentially locked by fastening screws. The fastening screws create an interaction force between the fixed sealing flange 223 and the outer shell 10, thereby compressing the first elastic seal 25.
[0103] It should be noted that when the end faces of the fixed sealing flange 223 and the outer shell 10 are very flat and have very little roughness, the flange surface of the fixed sealing flange 223 and the fixed sealing surface 12 of the outer shell 10 fit together. In this case, the sealing purpose can be achieved without the need for a seal.
[0104] Furthermore, the heat exchanger module 20 also includes a heat exchanger cover plate 26. A second elastic seal 27 is provided between the heat exchanger cover plate 26 and another fixed sealing flange 223. For example, the second elastic seal 27 (also known as a cover plate sealing strip) is affixed to the heat exchanger cover plate 26. The heat exchanger cover plate 26 and the fixed sealing flange 223 are circumferentially locked by fixing screws.
[0105] It can be seen that the fixing screws form an interaction force between the heat exchanger cover plate 26 and the other fixed sealing flange 223, thereby pressing the second elastic sealing member 27 tightly.
[0106] Please also refer to Figures 11 to 15 In the third type of heat exchanger module, the heat exchanger module 20 includes a heat exchanger body 21 and a fixed sealing shell 22 fixed to the heat exchanger body 21. The fixed sealing shell 22 is used to directly contact the outer wall of the outer shell 10 (the outer wall of the outer shell 10 is provided with a fixed sealing surface 12 located outside the installation opening 11), thereby achieving the purpose of sealing the installation opening 11.
[0107] Furthermore, to achieve a sealing effect, a first elastic seal 25 may be added between the fixed seal housing 22 and the outer shell 10, and the fixed seal housing 22 and the outer shell 10 are circumferentially locked by fastening screws. The fastening screws create an interaction force between the fixed seal housing 22 and the outer shell 10, compressing the first elastic seal 25.
[0108] It should be noted that, unlike the first heat exchanger module, the water inlet pipe 23 and the water outlet pipe 24 of the heat exchanger module 20 extend to the outside of the fixed sealing shell 22. In other words, the fixed sealing shell 22 cannot protect the water inlet pipe 23 and the water outlet pipe 24 at the first end of the heat exchanger body 21, but only serves to seal the installation opening 11 after docking with the outer shell 10.
[0109] The heat exchanger module 20 adopting the above-mentioned setting method exposes the water inlet pipe 23 and the water outlet pipe 24 located at the first end of the heat exchanger body 21, which greatly facilitates the disassembly and assembly of the water inlet pipe 23 and the water outlet pipe 24 with the external pipeline, and further improves the assembly and disassembly efficiency of the heat exchanger module 20.
[0110] In some embodiments, considering that the space for installing the heat exchanger module 20 is limited due to the layout of electrical devices and other heat dissipation devices inside the control cabinet, the installation port 11 for installing the heat exchanger module 20 often needs to be set at the edge of the control cabinet, wherein the installation cavity located inside the installation port 11 needs to be covered with a cover.
[0111] In this way, taking the rectangular mounting opening 11 as an example, three sides of the rectangular mounting opening 11 are formed by the cabinet body, and one side is formed by the cover plate. In this case, the fixed sealing flange 223 on the heat exchanger body 21 can be composed of three flange surfaces. The fixed sealing flange 223 composed of three flange surfaces is combined with the cover plate to form a closed-loop sealing flange surface, thereby forming a sealing structure for sealing the mounting opening 11.
[0112] A control cabinet provided in the present application includes a cabinet body 30, in which a water inlet external pipe 40 and a water outlet external pipe 50 are provided. The cabinet body 30 also includes a heat exchanger module as described in the above specific embodiment, which is arranged in the cabinet body 30. The water inlet external pipe 40 is connected to the water inlet pipe 23 of the heat exchanger module, and the water outlet external pipe 50 is connected to the water outlet pipe 24 of the heat exchanger module.
[0113] It should be emphasized that, due to the traditional method of installing the fin-tube heat exchanger as a whole inside the cavity, the pipeline needs to pass through the partition to lead out of the cavity external pipe, resulting in complex pipeline connections and detrimental to the reusability of the overall partition layout and architecture. In contrast, in the present application, due to the isolation of the partition 222 and the sealing of the first elastic seal 25, the second elastic seal 27 and the third elastic seal, the connection operation of the water inlet external pipe 40 and the water outlet external pipe 50 can be performed on the outside of the outer shell 10. This setting method of relocating the connection operation of the water inlet external pipe 40 and the water outlet external pipe 50 reduces the difficulty of installation and maintenance operations and simplifies the overall layout difficulty.
[0114] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
