Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a heat exchange unit, a heat exchange module and an air handling unit. Background Technology

[0002] The heat exchange module has a sensor to detect whether the heat exchange medium in the heat exchange pipeline is leaking. In related technologies, when the sensor is connected to the water receiving pan, the sensor is first connected to a fixed bracket, and then the fixed bracket is fixed to the side plate of the water receiving pan through a connecting structure. To ensure that the sensor is in the optimal sensing position, the relative positions between the fixed bracket and the side plate of the water receiving pan need to be set accordingly. In related technologies, when assembling the sensing component, the assembler needs to manually align the sensing component to a specific position before assembly, or use specific assembly positioning tools to position the relative position of the sensing component and the water receiving pan, which is relatively cumbersome.

[0063] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0064] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0065] The heat exchange module has a sensor to detect whether the heat exchange medium in the heat exchange pipeline is leaking. For ease of installation and maintenance, the sensor is connected to the outer casing of the heat exchange module, and the connection point on the casing makes it easier to access the corresponding location of the leaking heat exchange medium. In some cases, users already have an outer casing to house the heat exchange unit. Therefore, users only need to purchase the heat exchange unit within the heat exchange module and install it with their existing casing to form the heat exchange module. In this case, the outer casing of the heat exchange module needs to be removed, and the heat exchange unit needs to be sold separately. When sold separately, the sensor cannot be installed before leaving the factory, so it cannot be positioned in the optimal sensing position at the factory. Therefore, when the heat exchange unit is sold separately, the sensor can be fixed to the drip tray using a bracket. When the sensor assembly is connected to the drip tray, the assembly process requires manual alignment of the sensor assembly to a specific position before assembly, or the use of specific assembly positioning tools to determine the relative position of the sensor assembly and the drip tray, which is cumbersome.

[0066] When a sensor is connected to a water receiving tray, it is first connected to a fixed bracket, and then the fixed bracket is fixed to the side plate of the water receiving tray via a connecting structure. To ensure the sensor is in the optimal sensing position, the relative positions between the fixed bracket and the side plate of the water receiving tray need to be correspondingly set. In related technologies, changes in the shape and structure of the side plate of the water receiving tray may make it difficult to connect the original connection point between the water receiving tray and the fixed bracket. For example, in some scenarios, the heat exchange components of the heat exchange unit need to be connected using screws. In this case, to facilitate the operation of the screws connecting the heat exchange components with a screwdriver, an opening needs to be made in the side plate of the water receiving tray. This opening is intended to avoid the screwdriver, allowing it to pass laterally through the opening and drive the screws connecting the heat exchange components. However, if this opening on the side plate happens to be located at the location where the fixed bracket is connected, the connection position between the fixed bracket and the side plate of the water receiving tray needs to be adjusted. However, after adjusting the connection position, the sensor's position changes, making it difficult to guarantee that the sensor is in the optimal sensing position. Therefore, existing fixed brackets have poor adaptability to water receiving trays.

[0067] In view of this, please refer to Figures 1 to 5 The first aspect of this utility model provides a heat exchange unit 100, which includes a heat exchange component 110, a water receiving tray 120, and a sensing component 130. The heat exchange component 110 includes a heat exchange pipe 111 for transferring the heat exchange medium. The heat exchange pipe 111 can be made of metal materials such as copper or aluminum to ensure good thermal conductivity. The water receiving tray 120 is located on one side of the heat exchange component 110 along a first direction X. The water receiving tray 120 has a water receiving cavity 121 with an opening facing the heat exchange component 110 for collecting condensate from the heat exchange component 110. The water receiving tray 120 includes a base plate 122 and a side plate 123. The base plate 122 is located on one side of the heat exchange component 110 along the first direction X, and the side plate 123 is connected to the base plate 122 on one side along a second direction Y, which is perpendicular to the first direction X.

[0068] It should be noted that the actual relative positions of the heat exchange unit 100 and the water receiving tray 120 depend on the usage scenario of the heat exchange unit 100. In some embodiments, after the heat exchange unit 100 is installed, the first direction X can be vertical. In this case, the water receiving tray 120 is located below the heat exchange unit 100 to collect the condensate falling from the heat exchange unit 100 along the first direction X. In other embodiments, after the heat exchange unit 100 is installed, the first direction X may be horizontal and the third direction Z may be vertical. In this case, the heat exchange unit 100 may also include another water receiving container, which can be located on the side of the heat exchange unit 100 along the third direction Z, so that the other water receiving container is used to collect the condensate falling from the heat exchange unit 100 along the third direction Z. For ease of description, the following example illustrates the scheme where the heat exchange unit 100 is installed, the first direction X is vertical, and the water receiving tray 120 is located below the heat exchange assembly 110.

[0069] Please see Figure 3 and Figure 5 The sensing component 130 includes a sensor 131 and a mounting bracket 132. The sensor 131 is used to sense parameters such as the concentration of the heat exchange medium in the surrounding environment, and the mounting bracket 132 is used to mount the sensor 131 onto the water receiving tray 120.

[0070] One of the side plate 123 and the fixed bracket 132 is provided with a positioning protrusion 124, and the other is provided with a positioning hole 1325. The positioning protrusion 124 passes through the positioning hole 1325. This allows the fixed bracket 132 to be positioned and fixed to the water receiving tray 120, so that the sensor 131 can be accurately fixed in the optimal sensing position of the water receiving tray 120, ensuring accurate monitoring of the heat exchange medium parameters. At the same time, the cooperation of the positioning protrusion 124 and the positioning hole 1325 can quickly locate the relative position of the fixed bracket 132 and the side plate 123, thereby quickly locating the relative position of the sensing component 130 and the water receiving tray 120, so that the sensor 131 is in a preset optimal sensing position. It also enhances the stability of the fixed bracket 132 and the water receiving tray 120 and improves the durability of the overall structure. It effectively solves the problem of poor adaptability of traditional fixed brackets 132 and further optimizes the performance of the heat exchange unit 100. Furthermore, the matching design of the positioning protrusion 124 and the positioning hole 1325 makes the assembly process of the fixed bracket 132 without the need for auxiliary positioning tools or manual adjustment of the assembly position by the operator, thus improving the convenience of positioning the sensing component 130 and increasing the assembly efficiency.

[0071] In some embodiments, the side plate 123 is provided with a positioning protrusion 124, and the fixing bracket 132 is provided with a positioning hole 1325. The positioning hole 1325 is a through hole, and the side plate 123 is provided with a first guide hole communicating with the water receiving cavity 121. The positioning protrusion 124 is provided with a second guide hole, and the first guide hole communicates with the second guide hole. In other words, the positioning protrusion 124 can be used for positioning the fixing bracket 132 and can also serve as a guide channel to ensure that condensate water is smoothly discharged from the water receiving cavity 121, avoiding water accumulation that may affect the operation of the equipment.

[0072] In other embodiments, the positioning hole 1325 is a blind hole recessed into the side wall of the fixed bracket 132 facing the side plate 123. The positioning protrusion 124 can be inserted into the blind hole to form a stable snap-fit ​​structure, further simplifying the assembly steps, ensuring a tight fit between the fixed bracket 132 and the side plate 123, and improving the overall structural stability. Simultaneously, the blind hole design effectively prevents condensate leakage, enhancing the equipment's waterproof performance and extending its service life. Furthermore, the combination of the blind hole and the positioning protrusion 124 makes disassembly and maintenance more convenient, improving the maintainability of the equipment.

[0073] It should be noted that the positioning protrusion 124 can be disposed on the side of the side plate 123 near the water receiving cavity 121. Thus, the fixing bracket 132 can be disposed within the water receiving cavity 121 via the positioning protrusion 124, thereby fully utilizing the space of the water receiving cavity 121 and optimizing the overall layout. In some embodiments, the positioning protrusion 124 can also be disposed on the side of the side plate 123 away from the water receiving cavity 121, allowing the fixing bracket 132 to be installed externally for easy maintenance and adjustment. This design offers high flexibility, adapts to different installation requirements, ensures stable operation of the sensor 131 in various environments, and further enhances the overall performance of the heat exchange unit 100.

[0074] In some embodiments, the side plate 123 is provided with a positioning hole 1325, and the fixed bracket 132 is provided with a positioning protrusion 124. The positioning hole 1325 penetrates the side plate 123, and the positioning protrusion 124 is tightly fitted with the positioning hole 1325. The positioning protrusion 124 is provided with a third guide hole 1241 communicating with the water receiving cavity 121, and the fixed bracket 132 is provided with a fourth guide hole communicating with the third guide hole 1241. Through the communication between the third guide hole 1241 and the fourth guide hole, condensate can be smoothly discharged from the water receiving cavity 121, avoiding water accumulation and ensuring stable operation of the equipment. In this way, not only is the drainage efficiency improved, but the tightness of the connection between the fixed bracket 132 and the side plate 123 is also enhanced, further optimizing the waterproof performance and durability of the overall structure, ensuring that the sensing component 130 can work accurately in various environments. In addition, the tight fit between the positioning protrusion 124 and the positioning hole 1325 eliminates the need for additional fasteners during assembly, reducing the number of parts and lowering production costs. At the same time, it effectively reduces assembly errors, improves product consistency and reliability, ensures that the heat exchange unit 100 can operate efficiently under various working conditions, extends the service life of the equipment, and further enhances market competitiveness.

[0075] In other embodiments, the positioning protrusion 124 seals the positioning hole 1325 to prevent condensate from seeping out through the gap between the outer wall of the positioning protrusion 124 and the inner wall of the positioning hole 1325, thereby improving the waterproof performance of the device.

[0076] In some embodiments, the fixing bracket 132 is mounted on the side of the side plate 123 opposite to the water receiving cavity 121, and the fixing bracket 132 is provided with a flow guide connector on the side opposite to the positioning protrusion 124. The flow guide connector has a fifth flow guide hole communicating with the fourth flow guide hole. The flow guide connector diverts condensate to the outside of the water receiving tray through the fifth flow guide hole, avoiding water accumulation inside and ensuring that the equipment is dry.

[0077] The fixed bracket 132 includes multiple spaced-apart connecting structures 1321, and at least one connecting structure 1321 is arranged opposite to the side plate 123 along the second direction Y. The fixed bracket 132 is connected to the side plate 123 of the water receiving tray 120 through at least one of the multiple spaced-apart connecting structures 1321 (the connecting structure 1321 arranged opposite to the side plate 123 along the second direction Y). In this solution, since the fixed bracket 132 has multiple spaced-apart connecting structures 1321, when the part of the side plate 123 originally used to connect the fixed bracket 132 cannot be connected to the expected connecting structure 1321 due to structural changes, other connecting structures 1321 can be switched to connect the side plate 123. This ensures that even if part of the structure of the side plate 123 is adjusted, the relative position of the fixed bracket 132 and the side plate 123 can remain consistent, thereby enabling the sensor 131 to maintain a better sensing position and improving the adaptability of the fixed bracket 132 to water receiving trays 120 of different shapes.

[0078] Please see Figure 1 and Figure 6 In some embodiments, the third direction Z is perpendicular to the first direction X and the second direction Y, respectively. Multiple connecting structures 1321 are arranged sequentially at intervals along the third direction Z, or sequentially at intervals along the first direction X. In other embodiments, the connecting structures 1321 can be arranged not only sequentially at intervals along the third direction Z, but also sequentially at intervals along the first direction X. This arrangement allows the fixing bracket 132 to provide support points in two mutually perpendicular directions, enhancing the stability of the entire structure and allowing for flexible adjustment of the sensor 131's position as needed.

[0079] In addition, the connection structure 1321 can be arranged in a matrix on the plane formed by the first direction X and the third direction Z, or arranged along non-linear paths such as spirals or wavy lines. This diverse arrangement helps optimize the space utilization of the sensing components 130, and also better adapts to water trays 120 of different shapes and sizes. Furthermore, when multiple sensors 131 are involved, signal interference can be avoided and data acquisition accuracy can be improved by rationally planning the relative positions of each sensor 131.

[0080] The connection structure 1321 is specifically a through hole extending along the second direction Y. The sensing assembly 130 also includes threaded or riveted fasteners that pass through the through hole and are threaded or riveted to the side plate 123. This design allows the sensing assembly 130 to be securely mounted on the water tray 120 while facilitating disassembly and maintenance.

[0081] The multiple through holes enhance the installation flexibility of the sensing component 130, facilitating fixation in various locations. Furthermore, the multiple through holes allow for clearance between the water tray 120 and the heat exchange component 110, ensuring the mounting bracket 132 fits snugly against the side plate 123 without interfering with the overall structure of the heat exchange unit 100, thus improving the overall stability and lifespan of the equipment. Specifically, the connection between the water tray 120 and the heat exchange component 110 can be achieved using threaded fasteners. To improve assembly convenience, the side plate 123 is provided with clearance holes, allowing threaded fasteners or installation tools to pass smoothly through, enabling quick installation and disassembly.

[0082] When using threaded fasteners, such as a combination of screws and nuts, they provide adjustable tightening force, allowing the user to adjust the position of sensor 131 or replace sensor 131 as needed without removing the entire mounting bracket 132. Threaded connections also provide good anti-loosening properties, ensuring a stable connection even in vibrating environments.

[0083] Using riveted components simplifies the installation process by providing a permanent, one-time connection. For applications requiring fast installation or where avoiding additional parts (such as nuts) is desirable, riveting may be a more suitable choice. Furthermore, riveting offers greater vibration resistance and durability because the absence of moving parts reduces the likelihood of loosening over time. Other mechanical connection methods, such as snap-fit ​​connections and welding, can also be considered.

[0084] Please see Figure 5 and Figure 6 The mounting bracket 132 includes a first plate 1322 and a second plate 1323. The first plate 1322 is attached to the side of the water receiving tray 120 opposite to the water receiving cavity 121, while the second plate 1323 is attached to the bottom plate 122 opposite to the bottom wall of the heat exchange assembly 110. Specifically, the sensor 131 can be mounted on the first plate 1322, and the second plate 1323 provides additional stable support, ensuring that the entire mounting bracket 132 system remains stable even under extreme conditions. The first plate 1322 and the second plate 1323 are fixed together by at least one connecting element such as screws, bolts, or welds to form a robust whole. In some embodiments, the first plate 1322 and the second plate 1323 are integrally formed, including but not limited to sheet metal processing. The layout of the first plate 1322 and the second plate 1323 ensures the structural strength of the water receiving tray 120 while improving aesthetics, and also improves the convenience of maintenance.

[0085] All connecting structures 1321 are located on the first plate 1322, which allows the fixing bracket 132 to be directly connected to the side plate 123 through these structures, ensuring the accuracy and consistency of the installation position. The first plate 1322 serves as the main support, bearing the weight of the sensor 131 and other possible additional equipment; the second plate 1323 plays a supporting and positioning role, while also helping to distribute the load and prevent local stress concentration from causing deformation or damage.

[0086] In some embodiments, the sensor 131 is mounted on the side of the first plate 1322 near the heat exchange assembly 110. In this case, since the first plate 1322 is attached to the outside of the side plate 123, it can protect the sensor 131 from the influence of the external environment to a certain extent, such as moisture intrusion or dust accumulation, thereby extending the service life of the sensor 131.

[0087] To increase the flexibility and adaptability of the fixed bracket 132, an angle-adjustable joint structure can be added between the first plate 1322 and the second plate 1323. This allows the relative angle between the two to be adjusted according to the actual installation conditions, thereby better matching different geometries of the water receiving tray 120.

[0088] Please see Figure 5 and Figure 6 The mounting bracket 132 has a flat wall 1324 that fits against the side of the side plate 123 opposite to the water receiving cavity 121. This flat wall 1324 includes a first region 1324a and a second region 1324b. The first region 1324a fits against the side plate 123, ensuring structural stability and a good contact surface. The sensor 131 is mounted in the second region 1324b, which is located on the side of the side plate 123 opposite to the bottom plate 122. The design of the second region 1324b improves the installation accuracy of the sensor 131 while ensuring uniform force distribution on the water receiving tray 120.

[0089] The placement of sensor 131 in the second region 1324b allows it to be closer to the heat exchange assembly 110, enabling more accurate sensing of the heat exchange medium status in the surrounding environment. Simultaneously, because sensor 131 is located outside the side plate 123, it is not affected by water accumulation inside the water receiving chamber 121, improving the stability of its operating environment and reducing potential failure points. Furthermore, it facilitates inspection or replacement of sensor 131 by maintenance personnel without disassembling the entire water receiving tray 120 assembly.

[0090] To protect sensor 131 from external interference, a protective cover or sealing material can be added to the second region 1324b. This further enhances the waterproof and dustproof performance of sensor 131, making it suitable for outdoor or high-humidity environments. Alternatively, a data transmission module, such as a wireless communication chip, can be integrated into the second region 1324b to enable remote monitoring and automated control functions.

[0091] It should be noted that the fixed bracket 132 is installed on the side of the side plate 123 away from the water receiving cavity 121. The setting of the flat wall 1324 makes a certain space distance between the fixed bracket 132 and the heat exchange component 110, which helps to install the sensor 131, avoids interference between the sensor 131 and the heat exchange component 110, and ensures that the ventilation and heat dissipation performance of the heat exchange component 110 is not affected.

[0092] In some embodiments, the planar wall 1324 is located on the side of the first plate 1322 facing the side plate 123, and the wall surface of the second plate 1323 adjacent to the planar wall 1324 can abut against the side of the base plate 122 away from the heat exchange assembly 110, thereby providing additional support. Furthermore, this design allows the fixing bracket 132 to use the wall surface of the base plate 122 away from the heat exchange assembly 110 as an assembly reference. Since the heat exchange assembly 110, side plate 123, and other structures can all use the base plate 122 as an assembly reference, this ensures the assembly accuracy and stability of the entire system. When maintaining and replacing the sensor 131, maintenance personnel can quickly locate the sensor 131 and complete the maintenance or replacement work rapidly. In other words, this design helps reduce the positional error of the sensor 131, which not only ensures the installation accuracy of the sensor 131 but also improves the compatibility of the fixing bracket 132 with water trays 120 of different sizes.

[0093] Please see Figure 9 In some embodiments, the fixing bracket 132 includes a first plate 1322, which comprises a first portion 1322e, a second portion 1322f, and a third portion 1322g. The first portion 1322e is attached to the side wall of the side plate 123 away from the water receiving cavity 121, increasing the contact area between the fixing bracket 132 and the side plate 123. The second portion 1322f is connected to the first portion 1322e and attached to the end wall of the side plate 123 away from the bottom plate 122, providing support and improving the stability of the overall structure. The third portion 1322g is connected to the end of the second portion 1322f away from the first portion 1322e and extends in a direction away from the bottom plate 122. The sensor 131 is mounted on the wall surface of the third portion 1322g facing the heat exchange assembly 110. This improves the compatibility of the fixing bracket 132 with side plates 123 of different sizes, allowing the sensor 131 to adjust its installation position according to the specific dimensions of the side plate 123.

[0094] Specifically, the first part 1322e and the third part 1322g can be arranged in parallel, while the second part 1322f is bent relative to the first part 1322e and the third part 1322g, so that the first part 1322e and the second part 1322f can abut against the adjacent sides of the side plate 123 away from the water receiving cavity 121. This three-section design allows the fixing bracket 132 to better adapt to water receiving trays 120 and heat exchange components 110 of different shapes and sizes, providing greater flexibility. The design of the third part 1322g provides an ideal installation position for the sensor 131, allowing the sensor 131 to directly face the heat exchange component 110, ensuring the accuracy of the measurement results.

[0095] Please see Figures 1 to 3The drip tray 120 is designed with one or more first guide holes, which connect to the drip cavity 121 and are used to guide condensate water to the external drainage system. Specifically, the side plate 123 is provided with at least one first guide hole, so that condensate water can be discharged from the inside of the drip cavity 121 through the first guide hole. In addition, the drip tray 120 also includes a positioning protrusion 124, which is connected to the side of the side plate 123 opposite to the drip cavity 121 and is connected to the first guide hole to ensure that condensate water can flow out smoothly.

[0096] The fixed bracket 132 is fitted to the side wall of the side plate 123 away from the water receiving cavity 121 and is provided with a positioning hole 1325. A positioning protrusion 124 passes through the positioning hole 1325 of the fixed bracket 132, thereby achieving relative fixation between the positioning protrusion 124 and the fixed bracket 132. This design not only ensures the accuracy of the positioning protrusion 124's position but also enhances the stability of the entire structure due to the presence of the fixed bracket 132, preventing the positioning protrusion 124 from shifting due to vibration or other external forces during long-term use. Furthermore, the positioning protrusion 124 also serves to position the fixed bracket 132 during installation, simplifying the installation process and improving the system's reliability.

[0097] In some embodiments, sensor 131 is located on the side of side plate 123 away from bottom plate 122, that is, sensor 131 is above rather than below water tray 120. This arrangement allows sensor 131 to better monitor the condition of the heat exchange medium around heat exchange assembly 110, as it is directly exposed to the air and away from condensate areas that may affect its operation.

[0098] In other embodiments, when viewed along the second direction Y, sensor 131 at least partially overlaps with heat exchange assembly 110, enabling it to accurately capture the heat exchange medium or other physical parameters near heat exchange assembly 110. This arrangement not only helps improve measurement accuracy but also reduces interference between sensor 131 and other components, ensuring the authenticity and reliability of data acquisition.

[0099] Please see Figures 1 to 5 In some other embodiments, the heat exchange assembly 110 includes a bent end 112, which is spaced apart from the side plate 123 along a second direction Y. This provides sufficient space for the sensor 131, avoiding unnecessary contact or friction between them, while also ensuring that the drip tray 120 can effectively collect condensate.

[0100] It should be noted that the bend end 112 includes multiple welded bends, and the welding positions of these bends are the primary locations for heat exchange medium leakage. Therefore, the bend end 112 and the side plate 123 are spaced apart along the second direction Y, which helps provide installation space for the sensor 131. That is, by installing the sensor 131 close to the bend, leaks can be detected quickly and accurately, allowing for timely maintenance and repair. Furthermore, this design facilitates routine inspections and maintenance by maintenance personnel, improving the overall system's operational convenience and safety. To enhance safety, the sensor 131 can promptly identify even minor leaks in the heat exchange medium and send a signal to the control system, triggering an alarm or automatically closing relevant valves to prevent the spread of potential hazards.

[0101] In some embodiments, placing the sensor 131 on the side of the side plate 123 away from the base plate 122, while ensuring appropriate overlap with the heat exchange assembly 110, can significantly improve the working efficiency and accuracy of the sensor 131. The design of the bend end 112 further optimizes the overall layout of the system, satisfying both mechanical structural requirements and functional requirements, thereby providing users with a more efficient and stable heat exchange solution.

[0102] In addition, the sensor 131 can be deployed at multiple points to monitor multiple locations of the heat exchange component 110, forming a multi-point monitoring network, thereby achieving more comprehensive data collection.

[0103] Please see Figures 5 to 7 The fixed bracket 132 includes a first plate 1322, which is connected to the side plate 123 of the water receiving tray 120. The sensor 131 is mounted on the wall of the first plate 1322 facing the heat exchange assembly 110, ensuring that the sensor 131 can directly sense the environmental conditions around the heat exchange assembly 110, thereby detecting whether the heat exchange medium is leaking. To protect the sensor 131 and optimize its working environment, a first baffle 1322a is connected to the end of the first plate 1322 away from the base plate 122. Viewed along the first direction X, the first baffle 1322a covers the sensor 131, preventing external substances such as dust and water droplets from directly contacting the sensor 131, while maintaining good airflow around the sensor 131.

[0104] Specifically, when condensate flows down from the heat exchange component 110, it is blocked by the first baffle 1322a. The condensate drips along the edge of the first baffle 1322a onto the water receiving tray 120, preventing it from splashing directly onto the sensor 131 and ensuring that the surface of the sensor 131 remains dry, maintaining its normal operating condition. Furthermore, the first baffle 1322a 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 1322a can completely cover the sensor 131 along the first direction X, which neither affects the signal transmission of the sensor 131 nor hinders the sensor 131 from external interference, thereby extending the service life of the sensor 131 and improving the overall reliability of the system.

[0105] By placing the sensor 131 on the side of the first plate 1322 facing the heat exchange assembly 110 and covering the sensor 131 with the first baffle 1322a along the first direction X, external interference factors can be effectively shielded, ensuring the accuracy and long-term stability of the sensor 131. This also simplifies the maintenance and cleaning process, as routine maintenance can be performed without frequent disassembly or adjustment of the sensor 131.

[0106] Please see Figure 7 The first baffle 1322a has a first water-retaining wall 1322c on the side opposite to the sensor 131. This first water-retaining wall 1322c is inclined relative to the first direction X. Therefore, when condensate drips onto the first baffle 1322a, the first water-retaining wall 1322c can guide any liquid (such as condensate) that might 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 liquid erosion of the sensor 131 but also helps maintain its surface dryness, ensuring unimpeded signal transmission. In other words, condensate dripping onto the first baffle 1322a will flow along the inclined first water-retaining wall 1322c, preventing condensate from stagnating or even flowing back into the sensor 131 area, thereby effectively preventing the sensor 131 from getting damp. It should be noted that whether the first water-retaining wall 1322c is not perpendicular to the first direction X or not parallel to the first direction X, it can be considered that the first water-retaining wall 1322c is inclined relative to the first direction X.

[0107] In some embodiments, for ease of description, the directions perpendicular to the first direction X and the second direction Y are defined as the third direction Z. A second baffle 1322b is connected to one end of the first plate 1322 along the third direction Z. When viewed along the third direction Z, the second baffle 1322b completely covers the sensor 131, further enhancing the protection of the sensor 131. The second baffle 1322b is also designed using corrosion-resistant materials to ensure its stability and reliability even in harsh environments.

[0108] The second baffle 1322b has a second water-blocking wall 1322d on the side opposite to the sensor 131. The second water-blocking wall 1322d is inclined Z relative to the third side. Therefore, when condensed water drips onto the second baffle 1322b, the second water-blocking wall 1322d can guide the liquid to flow along the inclined surface, preventing it from flowing back to the sensor 131 area, further reducing the risk of the sensor 131 getting wet, and ensuring the stability and accuracy of signal transmission.

[0109] In some embodiments, please refer to Figure 8 The water receiving tray 120 includes a first tray 125 and a second tray 126. The first tray 125 is located on one side of the heat exchange assembly 110 along the first direction X, and the second tray 126 is located on the other side of the heat exchange assembly 110 along the third direction Z. The second tray 126 and the first tray 125 can operate independently. When the first direction X is parallel to the vertical direction, the condensate can be collected by the first tray 125, and the first baffle 1322a can block the condensate dripping along the first direction X, preventing the condensate from affecting the sensor 131. When the third direction Z is parallel to the vertical direction, the condensate is collected by the second tray 126, and the second baffle 1322b can block the condensate dripping along the third direction Z, ensuring that the sensor 131 is not affected. The independent design of the second tray 126 and the first tray 125 allows the fixing bracket 132 to effectively intercept condensate from different directions regardless of the installation orientation of the heat exchange assembly 110, further improving the protection effect of the sensor 131. This not only ensures the stable operation of sensor 131 in various environments, but also greatly reduces maintenance costs and improves the overall efficiency and reliability of the system.

[0110] A hydrophobic coating can be applied to the surfaces of the first water-retaining wall 1322c and / or the second water-retaining wall 1322d to further enhance the waterproof effect. The hydrophobic coating effectively reduces liquid adhesion, allowing condensate to slide off more quickly and preventing accumulation. This not only improves waterproof performance but also extends the service life of the equipment, ensuring that the sensor 131 maintains efficient operation even in complex environments, further enhancing the stability and reliability of the system.

[0111] Please see Figure 6 and Figure 7The mounting bracket 132 is provided with a connecting wall 1326, which is used to support and fix the sensor 131. Specifically, the sensor 131 is attached to this connecting wall 1326, and to ensure that the sensor 131 is securely mounted on the mounting bracket 132, a structure such as threaded fasteners can be used to fix the sensor 131 to the connecting wall 1326. The connecting wall 1326 has a protruding abutment 1327. The abutment 1327 contacts the surface of the sensor 131 and applies appropriate pressure, thereby firmly fixing the sensor 131 in a predetermined position. The abutment 1327 helps to prevent the sensor 131 from rotating relative to the mounting bracket 132 while mounted on the connecting wall 1326, further enhancing the stability of the sensor 131 installation.

[0112] Specifically, during the installation of sensor 131, sensor 131 can abut against the supporting part 1327, and then the threaded fastener is tightened. During the tightening process, the threaded fastener tends to rotate with the threaded fastener. At this time, the supporting part 1327 can provide a supporting force to sensor 131, preventing sensor 131 from rotating, so as to facilitate the installation of sensor 131. At the same time, it ensures that sensor 131 is tightly attached to the connecting wall surface 1326.

[0113] In some embodiments, the supporting portion 1327 may be welded to the first plate 1322 to ensure its structural stability. In other embodiments, the supporting portion 1327 may also be integrally stamped and bent from the first plate 1322 to form an integrated structure, thereby enhancing the strength and durability of the supporting portion 1327.

[0114] A second aspect of this invention provides a heat exchange module 200, which includes a heat exchange unit 100 as described in any of the above embodiments and a housing assembly 210. The housing assembly 210 defines a cavity for accommodating the heat exchange unit 100, and the cavity provides a closed and controlled operating environment for the entire system.

[0115] The housing assembly 210 may include four side shells. An air inlet is provided on one side of the housing assembly 210 along the first direction X, and an air outlet is provided on the opposite side. A water collection tray 120 is located on one side of the air inlet of the housing assembly 210. The water collection tray 120 has multiple perforations. After air enters the housing assembly 210 through the air inlet, it can penetrate the water collection tray 120 through these perforations and contact the heat exchange assembly 110, thereby exchanging heat. The heat exchange module 200 may also include a secondary water collection tray (i.e., a second tray 126). The secondary water collection tray is located on one side of the housing assembly 210 along the third direction Z, specifically on the side opposite to the sensor 131 and the second baffle 1322b along the third direction Z. The secondary water collection tray improves the compatibility of the heat exchange module 200 with multi-directional assembly, allows for more effective collection and discharge of condensate, further ensures a dry internal environment, reduces the impact of condensate on the equipment, and improves overall operating efficiency.

[0116] Specifically, the housing assembly 210 can be made of a robust and durable material, such as metal or high-strength plastic, to ensure sufficient mechanical strength and durability. The internal cavity shape of the housing assembly 210 matches the heat exchange unit 100, ensuring a tight fit between the two while leaving sufficient clearance for airflow to achieve efficient heat exchange.

[0117] The housing assembly 210 is also equipped with necessary interfaces and channels for connecting external pipes, power cords, and other auxiliary equipment. For example, inlet and outlet water pipes can be easily connected to the heat exchange assembly 110; while the sensor 131 signal line can be led out through a specially designed wire hole and connected to the control system. In addition, for ease of maintenance and repair, the housing assembly 210 is usually designed to be easily disassembled, for example, by using quick-release clips or screws for fixation.

[0118] Please see Figure 8 A third aspect of this invention also provides an air handling unit 300, which includes a heat exchange module 200 and a drive module 310 according to any of the above embodiments. The drive module 310 is capable of generating airflow for heat exchange with the heat exchange assembly 110. Specifically, the air handling unit 300 may further include an air guide module 320, which is capable of adjusting the direction and speed of the airflow generated by the drive module 310 to ensure uniform airflow distribution and improve heat exchange efficiency.

[0119] In some embodiments, the air guide module 320 and the drive module 310 are integrated within the housing assembly 210 and are closely connected to the heat exchange module 200 to form a compact integrated structure. Specifically, the heat exchange module 200 is disposed within the housing assembly 210 on one side near the air inlet, while the drive module 310 is located on the other side of the housing assembly 210. The two are connected through the air guide module 320 to form a highly efficient heat exchange system.

[0120] In other embodiments, the heat exchange module 200 and the drive module 310 are independently configured and connected via the air guide module 320. Thus, driven by the drive module 310, the airflow, after being heated or cooled by the heat exchange module 200, is precisely guided to the target area via the air guide module 320, ensuring uniform heat distribution and improving overall thermal efficiency. Furthermore, the independent configuration facilitates modular maintenance, reduces repair costs, and enhances system flexibility.

[0121] It should be noted that the drive module 310 may include a motor and a fan assembly, with the motor driving the fan assembly to generate directional airflow. The drive module 310 may also include a control module for adjusting the motor speed and fan angle, precisely controlling airflow parameters, and optimizing heat exchange. The control module is linked with a sensor system to monitor heat exchange medium leakage in real time, monitor ambient temperature and humidity, and automatically adjust the operating status to ensure efficient and stable system operation. The air guide module 320 may include an air guide duct and air guide blades. The air guide blade angle is adjustable to adapt to different environmental requirements, ensuring uniform airflow coverage of the target area and further improving heat exchange efficiency. The air guide duct may adopt a streamlined design to reduce airflow resistance and optimize airflow path. The air guide blades can be adjusted manually or electrically; electric adjustment can be remotely controlled via the control system. A turbulence device may be added inside the air guide duct to further optimize airflow distribution, reduce eddy currents, and improve heat exchange efficiency.

[0122] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0123] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0124] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
