[0062] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0063] The heat exchange module has a sensor for sensing whether the heat exchange medium in the heat exchange pipeline leaks. In the related art, when the sensor is connected to the first water receiving tray, the sensor is first connected to a fixed support, and then the fixed support is fixed to the side plate of the first water receiving tray through a connecting structure. In order to make the sensor be in the best sensing position, the relative positions between the fixed support and the side plate of the first water receiving tray need to be correspondingly arranged. In order to facilitate the disassembly and assembly of the fixed support, the fixed support is attached to the side of the side plate of the first water receiving tray which is away from the water receiving cavity, that is, the fixed support is connected to the outer side of the first water receiving tray. In this scheme, the horizontal distance between the sensor connected to the fixed support and the heat exchange assembly is far, and the sensing precision is not high.

[0064] In the initial improvement scheme, the applicant offsets the fixing plate (for connecting the side plate of the water pan) and the connecting plate (for connecting the sensor) of the fixing support in the thickness direction, so that the connecting plate is offset towards the direction close to the heat exchange assembly. When the fixing support is assembled, the fixing plate is connected to the side plate away from the water receiving cavity, and the connecting plate is located on the side of the side plate facing the water receiving cavity. In this scheme, the fixing plate is located on the outer side of the side plate, so that the disassembly and assembly of the fixing support are more convenient, and the connecting plate is located on the inner side of the side plate, so that the sensor is closer to the heat exchange assembly. However, in this scheme, the offset size of the fixing plate and the connecting plate along the thickness direction of the side plate cannot be too large, otherwise the sensor is prone to positional interference with the heat exchange assembly. When the offset size of the fixing plate and the connecting plate along the thickness direction of the side plate is small (for example, the offset size is only slightly larger than the thickness size of the side plate), when the fixing support is installed, the operator may not know that the connecting plate needs to be installed on the side of the side plate facing the water receiving cavity, and forcibly press the lower end of the connecting plate on the side of the side plate away from the water receiving cavity, so that the positional offset of the connecting plate does not achieve the expected effect of the structural design.

[0065] In view of this, please refer to Figures 1 to 11 The utility model provides a kind of heat exchange module 100, the heat exchange module 100 includes heat exchange assembly 110, first water pan 120 and sensing assembly 130.Heat exchange assembly 110 includes the heat exchange pipeline 111 for transmission heat exchange medium, the heat exchange pipeline 111 can be copper pipe, aluminum pipe etc.

[0066] It should be noted that the actual relative position of the heat exchange assembly 110 and the first water receiving tray 120 depends on the use scenario of the heat exchange assembly 110. In some embodiments, after the heat exchange assembly 110 is installed, the first direction X can be a vertical direction, and at this time, the first water receiving tray 120 is located below the heat exchange assembly 110 to collect the condensed water falling along the first direction X. In some embodiments, after the heat exchange assembly 110 is installed, the first direction X can be a horizontal direction, and the third direction Z can be a vertical direction, and at this time, the heat exchange assembly 110 can further include another water receiving container, which can be located on one side of the heat exchange assembly 110 along the third direction Z, so that the other water receiving container is used to collect the condensed water falling along the third direction Z at this time. For ease of description, the following is exemplified by taking the case where the first direction X is a vertical direction after the heat exchange assembly 110 is installed, and the first water receiving tray 120 is located below the heat exchange assembly 110.

[0067] Please refer to Figures 7 to 11 The sensing assembly 130 includes a sensor 131 and a fixing bracket 132 connected to each other. The sensor 131 is used to sense the heat exchange medium around itself. The fixing bracket 132 includes a fixing plate 1321 and a connecting plate 1322. The fixing plate 1321 is connected to the side plate 123 and adheres to the side wall of the side plate 123 away from the water receiving cavity 121. The connecting plate 1322 connects the sensor 131 on the side facing the heat exchange assembly 110. The side of the connecting plate 1322 close to the bottom plate 122 is provided with a foolproof protrusion 1323 protruding in the direction close to the heat exchange assembly 110. The foolproof protrusion 1323 is configured to make the connecting plate 1322 assembled to the side of the side plate 123 close to the heat exchange assembly 110, so as to ensure that the connecting plate 1322 can be correctly assembled to the side of the side plate 123 close to the heat exchange assembly 110. The design of the foolproof protrusion 1323 not only ensures the correct installation direction of the connecting plate 1322, but also enhances the overall stability of the structure and prevents loosening caused by vibration or external force.

[0068] In the scheme, the connection plate 1322 is provided with a foolproof protrusion 1323 protruding towards the direction close to the heat exchange assembly 110 on the side close to the bottom plate 122, and the foolproof protrusion 1323 is configured to make the connection plate 1322 be assembled to the side of the side plate 123 close to the heat exchange assembly 110. In other words, when the installer does not know that the connection plate 1322 needs to be assembled to the side of the side plate 123 facing the water collecting cavity 121, if the position of the connection plate 1322 and the fixed plate 1321 along the thickness direction of the side plate 123 deviates by a small size, the original scheme may appear the case that the installer forcibly presses the lower end of the connection plate to the side of the side plate away from the water collecting cavity for installation. In the scheme, the foolproof protrusion 1323 is provided, so that when the installer sets the connection plate 1322 on the side of the side plate 123 away from the water collecting cavity 121, the foolproof protrusion 1323 will abut the side of the side plate 123 away from the water collecting cavity 121, so that the connection plate 1322 is spaced apart from the side plate 123, and the spacing size of the fixed plate 1321 and the side plate 123 is larger, so that the fixed plate 1321 cannot be normally assembled. At this time, the installer can be reminded to move the connection plate 1322 to the side of the side plate 123 facing the water collecting cavity 121 for installation, so as to realize the normal assembly of the fixed support 132. That is, the structure of the foolproof protrusion 1323 can improve the installation accuracy of the fixed support 132 and reduce the probability of misassembly.

[0069] Compared with the related art, the sensor 131 is installed on the side of the side plate 123 close to the heat exchange assembly 110 through the connection plate 1322, which effectively shortens the distance between the sensor 131 and the heat exchange assembly 110, reduces the delay of signal transmission, and improves the sensing accuracy. In addition, compared with the related art, the fixed support 132 is fixed on the side of the side plate 123 away from the water collecting cavity 121 through the fixed plate 1321, which is beneficial to improve the installation convenience of the fixed support 132. The sensor 131 is installed on the side of the side plate 123 close to the water collecting cavity 121 through the connection plate 1322, so that the distance between the sensor 131 and the heat exchange assembly 110 is closer, which is beneficial to improve the sensing accuracy of the sensor 131.

[0070] In addition, in related technologies, in order to facilitate the installation of the support, a protrusion or a groove for guiding is arranged on the support. In the present application, the design of the foolproof protrusion 1323 makes the installation position of the connecting plate 1322 unique during the assembly process, avoiding installation errors and further improving assembly efficiency and system reliability. It should be noted that in related technologies, the protrusion for guiding is prone to positional deviation due to misoperation during the assembly process, and the protrusion in related technologies is prone to elastic deformation during guiding, which causes the position of the structure for installing the sensor 131 to change, thereby causing the positioning position of the sensor 131 to be unstable. In order to ensure the accurate positioning of the connecting plate 1322, the connecting plate 1322 of the present application is provided with a foolproof protrusion 1323, which not only enhances the structural strength of the connecting plate 1322 to avoid elastic deformation, but also assists the operator to quickly and accurately install the fixing support 132, reduces the assembly difficulty, and improves the stability of the overall structure. The design of the foolproof protrusion 1323 of the present application makes it easy for the operator to identify the correct position by the foolproof protrusion 1323 even if the operator's line of sight is limited during the installation process, thereby ensuring the accuracy and efficiency of the assembly. In addition, it also reduces the maintenance frequency caused by improper assembly, prolongs the service life of the equipment, and further improves the long-term stability and reliability of the system.

[0071] Please refer to Figures 9 to 11 The foolproof protrusion 1323 is connected to the end of the connecting plate 1322 close to the bottom plate 122, and the connecting plate 1322 and the foolproof protrusion 1323 are integrally connected. This not only simplifies the manufacturing process, i.e. the connecting plate 1322 does not need additional assembly steps to add the foolproof protrusion 1323. Moreover, since the foolproof protrusion 1323 and the connecting plate 1322 are integrally connected, the structural strength and durability of the fixing support 132 are improved. In other words, the arrangement of the foolproof protrusion 1323 not only ensures the stability of the connecting plate 1322, but also facilitates the operator to quickly identify the correct position by touch during assembly, further improving assembly efficiency and accuracy. In addition, the integrated design reduces the number of parts, reduces manufacturing costs, and enhances the compactness and reliability of the overall structure.

[0072] In some embodiments, the foolproof protrusion 1323 can also be arranged at any position on the side of the connecting plate 1322 close to one end of the bottom plate 122 and away from the side plate 123.

[0073] Please refer to Figure 10, the angle a between the thickness direction of the connecting plate 1322 and the thickness direction of the foolproof protrusion 1323 satisfies: 60°≤a≤90°. To ensure that an effective structural support angle is formed between the connecting plate 1322 and the foolproof protrusion 1323, not only the mechanical strength of the entire fixing support 132 is enhanced, but also the correct installation position and stability of the sensor 131 are ensured. In this way, displacement or damage of the sensor 131 caused by external vibration or impact can be effectively prevented, thereby improving the overall reliability of the heat exchange module 100.

[0074] To adapt to different environmental conditions and installation requirements, the structural performance can be optimized by adjusting the angle between the connecting plate 1322 and the foolproof protrusion 1323. Exemplarily, the angle a can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc. In application scenarios requiring higher vibration resistance, the angle a can be selected to be close to 90° to provide stronger support force; while in the case of limited space, the angle a can be selected to be a smaller angle (e.g. close to 60°) to reduce the overall space occupied while maintaining a certain support strength.

[0075] It should be noted that in the related art, the protrusion structure for guiding is usually designed with a small angle between the protrusion structure and the support to ensure the accuracy of the guidance. However, the foolproof protrusion 1323 in the present application breaks through the limitation of the traditional guiding structure, achieving the dual effect of precise positioning and high-strength support through a larger angle a, which not only ensures the assembly accuracy but also improves the structural stability, and is suitable for a wider range of application scenarios.

[0076] Please refer to Figure 4 and Figure 5 , the connecting plate 1322 abuts against the side wall of the side plate 123 facing the water receiving cavity 121, and the sensor 131 is installed on the side of the connecting plate 1322 close to the heat exchange assembly 110. This shortens the distance between the sensor 131 and the heat exchange assembly 110, effectively improving the sensing accuracy of the sensor 131 on the heat exchange medium. At the same time, the contact area between the connecting plate 1322 and the side plate 123 is increased, effectively enhancing the connection stability of the two, and effectively dispersing the external force acting on the connecting plate 1322, reducing the occurrence of local stress concentration.

[0077] The direction perpendicular to the first direction X and the second direction Y is defined as the third direction Z. In some embodiments, the connecting plate 1322 is located on one side of the fixing plate 1321 along the third direction Z. In this way, during the installation of the fixing support 132 on the side plate 123, the side plate 123 can be located between the fixing plate 1321 and the connecting plate 1322, forming a stable three-dimensional support structure, ensuring the stability of the fixing support 132 in all directions, and further improving the vibration resistance and durability of the sensor assembly 130.

[0078] In some embodiments, the positional relationship between the fixed plate 1321 and the connecting plate 1322 can also be that at least part of the connecting plate 1322 is spaced apart from the fixed plate 1321 in the second direction Y, which not only ensures the necessary spacing between the fixed plate 1321 and the connecting plate 1322, but also allows the connecting plate 1322 to have certain adjustment flexibility in the third direction Z, facilitating the adaptation to slight differences in different installation environments. At the same time, the spaced arrangement can effectively avoid structural deformation caused by thermal expansion, further improving the durability and reliability of the overall structure.

[0079] Please refer to Figure 11 and Figure 10 , the connecting plate 1322 has a first side wall 1322a abutting the sensor 131, and the fixed plate 1321 has a second side wall 1321a abutting the side plate 123. The included angle β between the first side wall 1322a and the second side wall 1321a satisfies: β≤45°. This ensures the close fit between the sensor 131 and the side plate 123, reduces installation errors, and at the same time avoids the sensor 131 being too close to the heat exchange assembly 110 to affect the sensing effect of the sensor 131 on the heat exchange medium. Exemplarily, the included angle β can be 45°, 40°, 35°, 30°, 25°, etc. The smaller the value of β, the higher the abutting degree of the connecting plate 1322 and the side plate 123, and a smaller angle can also effectively disperse the acting force, preventing the sensor 131 from being displaced or damaged due to external force, thereby improving the overall performance and service life of the equipment. Further, the included angle β can be between 30° and 45° to balance the installation precision and strength of the sensor 131, meeting the diversified working condition requirements.

[0080] Please refer to Figure 11 , the fixed support 132 further includes a base plate 1324 connected to the connecting plate 1322 and the fixed plate 1321 at one end close to the bottom plate 122. The connecting plate 1322 has a first side wall 1322a abutting the sensor 131, and the fixed plate 1321 has a second side wall 1321a abutting the side plate 123. The base plate 1324 has a third side wall 1324a facing the heat exchange assembly 110, which intersects the first side wall 1322a and the second side wall 1321a, and the first side wall 1322a, the second side wall 1321a and the third side wall 1324a are all planar walls. Among them, the first side wall 1322a and the third side wall 1324a are crosswise arranged, and the second side wall 1321a and the third side wall 1324a are coplanarly arranged.

[0081] Compared with the first side wall and the second side wall being spaced apart (i.e. no intersection between the two) or compared with the connecting plate being connected to the base plate through the bending structure to realize the spacing and parallelism of the first side wall and the second side wall, the fixing support 132 in the application is more simple and convenient to process. Specifically, the connecting plate 1322 and the fixing plate 1321 have a separation gap along the second direction Y, and the connecting plate 1322 is folded and inclined towards the third direction Z compared with the fixing plate 1321, so as to realize the intersection of the first side wall 1322a and the third side wall 1324a and the coplanar arrangement of the second side wall 1321a and the third side wall 1324a.

[0082] The base plate 1324 can effectively improve the connection reliability of the connecting plate 1322 and the fixing plate 1321, so that the fixing support 132 can effectively support and stabilize the sensor 131. Specifically, the third side wall 1324a of the base plate 1324 is made of the same material as the first side wall 1322a and the second side wall 1321a, so as to ensure that the thermal expansion coefficient of the whole fixing support 132 is consistent, thereby reducing the structural stress caused by temperature change. In addition, the planar design of the base plate 1324 simplifies the manufacturing process and facilitates accurate mechanical processing, ensuring the assembly accuracy and reliability of the fixing support 132. The connection mode of the base plate 1324 with the connecting plate 1322 and the fixing plate 1321 can adopt welding, screw fixing or other mechanical fixing mode. The base plate 1324, the connecting plate 1322 and the fixing plate 1321 can also adopt integrated connection. In addition, in order to further ensure the stability and reliability of the overall structure, reinforcing ribs can be additionally arranged at the connecting part of the base plate 1324 and the connecting plate 1322 to disperse the stress concentration area.

[0083] Please refer to Figures 9 to 11 In some embodiments, the fixing support 132 further comprises a base plate 1324 connected to the connecting plate 1322 and the fixing plate 1321 respectively at one end close to the bottom plate 122. The end of the base plate 1324 away from the bottom plate 122 is provided with a first baffle 1324b, which extends in the direction close to the heat exchange assembly 110 and covers the sensor 131 along the first direction X. The design of the first baffle 1324b effectively protects the sensor 131 from external factors (such as condensate droplets, dust, etc.), ensuring the reliability and accuracy of the work of the sensor 131.

[0084] Specifically, when the condensed water flows down from the heat exchange assembly 110, it is blocked by the first baffle 1324b and drips along the edge of the first baffle 1324b to the first water pan 120, avoiding direct splashing onto the sensor 131, ensuring the surface of the sensor 131 is dry, and maintaining its normal working state. In addition, the first baffle 1324b is made of a material with good corrosion resistance and waterproof performance to ensure that it does not deform or fail during long-term use. The first baffle 1324b can completely cover the sensor 131 in the first direction X, neither affecting the transmission of the sensor 131 signal nor maximizing the protection of the sensor 131 from external interference, thereby prolonging the service life of the sensor 131 and improving the overall reliability of the system.

[0085] The side of the first baffle 1324b facing away from the sensor 131 has a first water blocking wall, which is arranged obliquely with respect to the first direction X. Thus, when the condensed water drips onto the first baffle 1324b, the first water blocking wall can guide any liquid (such as condensed water) that may fall onto the sensor 131 away from the sensor 131, rather than allowing it to directly impact the surface of the sensor 131. This not only reduces the risk of the sensor 131 being eroded by liquid, but also helps to maintain its surface dry, ensuring that signal transmission is not hindered. In other words, the condensed water that drips onto the first baffle 1324b will flow along the obliquely arranged first water blocking wall, avoiding the condensate from stagnating or even flowing back to the sensor 131 area, thereby effectively preventing the sensor 131 from being damp. It should be noted that the first water blocking wall is not perpendicular to the first direction X, or the first water blocking wall is not parallel to the first direction X, both of which can be considered as the first water blocking wall being arranged obliquely with respect to the first direction X.

[0086] In some embodiments, a direction perpendicular to the first direction X and the second direction Y is defined as the third direction Z. The heat exchange module 100 can further include a second water pan located on one side of the heat exchange assembly 110 along the third direction Z. When the third direction Z is a vertical direction, the second water pan is used to collect condensed water falling from the heat exchange assembly 110 along the third direction Z. The side of the connecting plate 1322 facing away from the second water pan is provided with a second baffle 1324c, which is also arranged to extend towards the heat exchange assembly 110. In the third direction Z, the second baffle 1324c can cover the sensor 131, further enhancing the protection effect of the sensor 131, avoiding the sensor 131 from being affected by external factors (such as condensed water dripping, dust, etc.), and ensuring the reliability and accuracy of the sensor 131 working.

[0087] The second baffle 1324c has a second water-blocking wall on the side facing away from the sensor 131, which is arranged obliquely with respect to the third direction Z. Thus, when condensate drops onto the second baffle 1324c, the second water-blocking wall can guide the liquid to flow along the inclined surface, avoiding its backflow to the area of the sensor 131, further reducing the risk of the sensor 131 being wet, and ensuring the stability and accuracy of signal transmission. Under the guidance of the second water-blocking wall, the condensate flows smoothly to the second water pan, forming an effective drainage path. The double protection mechanism works together to greatly improve the adaptability of the sensor 131 in complex environments, ensuring its long-term stable operation, and further consolidating the overall performance of the system.

[0088] Please refer to Figures 5 to 7 The side of the fixed plate 1321 close to the bottom plate 122 is provided with a first limiting groove 1321b extending along the first direction X. At the same time, the side of the side plate 123 away from the heat exchange assembly 110 is provided with a corresponding first limiting protrusion 1231, which is arranged in the first limiting groove 1321b. Through the cooperation of the limiting groove and the limiting protrusion, the accurate alignment and stable connection between the fixed plate 1321 and the side plate 123 are ensured, thereby improving the structural stability and reliability of the entire heat exchange module 100. The design of the limiting groove and the limiting protrusion not only simplifies the assembly process, but also effectively prevents the displacement of components caused by external vibration or impact.

[0089] In order to further enhance the limiting function and adapt to different installation requirements, multiple limiting grooves can be provided on the fixed plate 1321, and corresponding number of limiting protrusions can be provided on the side plate 123. In addition, according to different specific application scenarios, the shape, size and spacing of the limiting groove and the limiting protrusion can also be adjusted to optimize their limiting effect. For example, in the case of higher precision positioning, trapezoidal or other non-circular cross-section limiting groove and limiting protrusion design can be used to increase the contact area and friction, thereby providing stronger torsional resistance.

[0090] Please refer to Figure 5In some embodiments, the end of the first limiting protrusion 1231 away from the bottom plate 122 abuts against the wall of the first limiting groove 1321b away from the bottom plate 122. Such a design ensures that the fixing plate 1321 will not easily slide or shift even when subjected to external forces, thereby enhancing the stability of the overall structure. In yet some embodiments, the fixing plate 1321 further comprises a second limiting groove 1321c extending along the first direction X and spaced apart from the first limiting groove 1321b. The side plate 123 away from the heat exchange assembly 110 is provided with a second limiting protrusion 1232 that is arranged to pass through the second limiting groove 1321c and abut against the wall of the second limiting groove 1321c away from the bottom plate 122. This double limiting mechanism makes the position of the fixing bracket 132 unique in the first direction X and the second direction Y, thereby improving the installation convenience of the fixing bracket 132 and enhancing the connection strength and stability between the fixing plate 1321 and the side plate 123. As a result, the sensing assembly 130 can also be applied to high-vibration environments.

[0091] Referring to Figure 6 In some embodiments, the side plate 123 away from the heat exchange assembly 110 is provided with a second limiting protrusion 1232 extending along the first direction X. The fixing plate 1321 comprises a fixing portion 1321d between the first limiting protrusion 1231 and the second limiting protrusion 1232, which is connected to the side plate 123 and abuts against the first limiting protrusion 1231 and the second limiting protrusion 1232, respectively. The close cooperation between the first limiting protrusion 1231, the second limiting protrusion 1232 and the fixing portion 1321d on the fixing plate 1321 ensures accurate and stable connection between the fixing plate 1321 and the side plate 123. This not only improves the assembly accuracy, but also effectively prevents the displacement of components due to vibration or external impact, thereby enhancing the stability and reliability of the overall structure.

[0092] Referring to Figure 5 The connecting plate 1322 is provided with a connecting structure 1322b for connecting the sensor 131, which is protruded from the side wall of the connecting plate 1322 away from the heat exchange assembly 110. The side of the side plate 123 away from the bottom plate 122 is provided with a recess 1233 recessed towards the bottom plate 122, and the connecting structure 1322b can be located in the recess 1233. The design of the recess 1233 not only optimizes the space utilization and reduces the volume of the entire device, but also facilitates the installation operation of the sensor 131. Specifically, the sensor 131 can be fixed to the connecting plate 1322 through the connecting structure 1322b, and at this time the design of the recess 1233 can avoid the connecting structure 1322b to facilitate the installation operation of the sensor 131, thereby maintaining the stability of the sensing assembly 130 and the reliability of long-term operation.

[0093] The installation position of the sensor 131 on the fixing bracket 132 can be adjusted according to the actual requirements of the sensor 131, etc. For example, the sensor 131 has a first installation position and a second installation position on the fixing bracket 132. Please refer to Figure 7 , the sensor 131 is located at the first installation position of the fixing bracket 132. Please refer to Figure 8 , the sensor 131 is located at the second installation position of the fixing bracket 132 and is installed on the connecting plate 1322 through the connecting structure 1322b.

[0094] Please refer to Figure 1 and Figure 2 , the heat exchange module 100 further comprises a housing assembly 140 provided with a receiving cavity 141, and the heat exchange assembly 110, the first water pan 120 and the sensing assembly 130 are all arranged in the receiving cavity 141. The housing assembly 140 comprises a housing body 142 and an outer baffle 143, the housing body 142 is provided with an opening 1421 communicating with the receiving cavity 141, and the outer baffle 143 is connected to the housing body 142 and covers the opening 1421, so as to ensure that the entire internal structure is well protected. The outer baffle 143 further comprises a first plate body 1431 and a second plate body 1432. The heat exchange assembly 110 comprises an external joint 150 for transmitting the heat exchange medium, and the external joint 150 penetrates through and is connected to the first plate body 1431. The second plate body 1432 is detachably connected to the housing body 142 and the first plate body 1431, so as to facilitate maintenance and overhaul. The side plate 123 and the sensing assembly 130 are both located at one side of the receiving cavity 141 close to the outer baffle 143, which not only facilitates the installation and adjustment of the sensor 131, but also enables the condensed water to flow smoothly into the first water pan 120.

[0095] Specifically, when the sensing assembly 130 needs to be overhauled, the shell body 142 and the second plate body 1432 can be removed so that the sensing assembly 130 is at least partially exposed. Since the fixing plate 1321 is installed on the side of the side plate 123 away from the heat exchange assembly 110, and the connecting plate 1322 is located on the side of the side plate 123 close to the heat exchange assembly 110, the sensing assembly 130 can be removed by only removing the fixing bracket 132 on the side of the side plate 123 away from the heat exchange assembly 110, so that the maintenance process is more convenient and fast. After the overhaul is completed, the sensing assembly 130 is installed on the side plate 123. Due to the existence of the first plate body 1431 (the first plate body 1431 is provided to ensure the stability of the external joint 150 and avoid leakage of the heat exchange medium caused by collision), part of the line of sight is blocked, which makes the installation of the sensing assembly 130 very difficult and prone to installation errors. However, in the present application, the connecting plate 1322 is provided with a foolproof protrusion 1323, which can ensure that the sensing assembly 130 can only be installed in the correct direction and position.

[0096] In some embodiments, in order to further improve the convenience of maintenance operation, only the second plate body 1432 can be removed, and the connection state of the shell body 142 and the first plate body 1431 is maintained. Then at least part of the sensing assembly 130 can be exposed at the opening 1421, so as to facilitate the operation of the maintenance personnel. At the same time, the connection state of the first plate body 1431 and the shell body 142 can further improve the connection reliability of the external joint 150 and the first plate body 1431, ensure the stability of the state of the external joint 150, and avoid the leakage of the heat exchange medium caused by the collision of the external joint 150 due to the disassembly of the first plate body 1431.

[0097] It should be noted that due to the arrangement of the external joint 150 for introducing or discharging the heat exchange medium into the heat exchange assembly 110, special attention should be paid to prevent leakage of the heat exchange medium during maintenance of the heat exchange module 100. In order to ensure the connection reliability of the external joint 150, the shell assembly 140 needs to avoid applying force to the external joint 150 during disassembly. Therefore, the shell assembly 140 includes a shell body 142 and an outer baffle 143. When the heat exchange module 100 is maintained and repaired, the shell body 142 is removed to ensure that the outer baffle 143 still maintains the connection state with the external joint 150, so as to avoid damage to the external joint 150 caused by collision and cause uncontrollable leakage of the heat exchange medium. In addition, the sensing assembly 130 is installed on the side plate 123 close to the outer baffle 143, so that the sensor 131 can monitor the sealing condition of the external joint 150 in real time, so as to judge whether the external joint 150 leaks, and then take timely measures.

[0098] Please refer to Figure 2In some embodiments, the connecting plate 1322 at least partially coincides with the first plate body 1431 in the second direction Y, which optimizes the space utilization and provides additional protection for the sensor 131 from external factors. In yet some embodiments, the fixing plate 1321 at least partially coincides with the second plate body 1432, which not only improves the compactness of the overall structure, but also enhances the connection strength between the fixing plate 1321 and the shell assembly 140, ensuring stability and reliability under various working conditions.

[0099] Referring to Figures 1 to 4 The second aspect of the utility model further provides an air handling unit 10, which comprises the heat exchange module 100 described in any of the above embodiments, and a driving module. The driving module is designed to generate airflow for effective heat exchange with the heat exchange assembly 110.

[0100] The driving module can include one or more fans or blower units that can adjust the air speed and volume according to demand, thereby achieving an efficient heat exchange process. To ensure optimal performance, the driving module also includes an intelligent control system that can automatically adjust the fan speed based on real-time monitoring data such as temperature, humidity, etc., ensuring that the system always operates in an optimal state.

[0101] Specifically, the air handling unit 10 can also include an air guide module that can adjust the direction and speed of the airflow generated by the driving module, ensuring uniform airflow distribution and improving heat exchange efficiency.

[0102] In some embodiments, the air guide module and the driving module are integrated within the shell assembly 140 and are closely connected to the heat exchange module 100, forming a compact overall structure. Specifically, the heat exchange module 100 is arranged near the air inlet side of the shell assembly 140, and the driving module is located on the other side of the shell assembly 140, both connected by the air guide module to form an efficient heat exchange system.

[0103] In other embodiments, the heat exchange module 100 and the driving module are independently arranged and connected through the air guide module, so that under the driving action of the driving module, the airflow is heated or cooled by the heat exchange module 100 and then precisely guided to the target area through the air guide module, ensuring uniform heat distribution and improving overall thermal efficiency. In addition, the independent design facilitates modular maintenance, reduces maintenance costs, and enhances system flexibility.

[0104] It should be noted that if the embodiment of the utility model has the direction indication (such as up, down, left, right, front, back, etc.), the direction indication is only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture, if the specific posture changes, the direction indication also changes accordingly. When the direction reference is introduced in the specific embodiment, if the direction is not specially limited as one-way, the direction can be one-way or bidirectional (two parallel and opposite directions), and the specific one-way or bidirectional is based on the realization of the ordinary skill in the art. When the direction reference is bidirectional, it is considered that two different embodiments in parallel are introduced.

[0105] In addition, if the embodiment of the utility model has the description of "first", "second", etc., the description of "first", "second", etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, it means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skill in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection of the utility model.
