Description

Technical Field

[0001] This utility model relates to a heat exchanger for a dehumidifier, belonging to the field of heat exchangers. Background Technology

[0002] As the core component of a dehumidifier, the performance and manufacturing process of the heat exchanger directly affect the dehumidification efficiency, energy consumption, and reliability of the entire machine. Currently, this type of heat exchanger is generally produced using a mold formed by the joining of two parts, namely, by closing the upper and lower molds, a channel structure is formed inside for the heat exchange tubes to pass through and for heat dissipation.

[0003] However, this traditional top-and-bottom mold manufacturing method has significant limitations. First, the high precision required during production and the complex mold structure lead to cumbersome manufacturing processes, difficult assembly, and low production efficiency. Furthermore, mold misalignment can easily affect product consistency and sealing. Second, and more importantly, the mold structure is typically a fixed design, with no flexibility in adjusting the internal flow channel spacing and layout, making it difficult to adapt to heat exchange tubes of different densities, arrangements, or diameters. When products require design changes based on different needs such as dehumidification capacity, air resistance, and energy efficiency, especially when adjusting the density of heat exchange tubes to optimize performance, it often necessitates redesigning and manufacturing the entire mold. This not only extends the development cycle but also significantly increases production costs, severely restricting the flexibility of product serialization and market application.

[0004] In view of this, it is indeed necessary to improve the existing heat exchangers to solve the above problems. Utility Model Content

[0021] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] Please see Figures 1 to 4As shown, this utility model discloses a heat exchanger 100 for a dehumidifier. The heat exchanger 100 includes a detachably connected upper cover 1, a heat exchange body 2, and a lower cover 3. The heat exchange body 2 includes a base and a plurality of heat exchange tubes 22 disposed on the base. Two bases are provided, respectively located on opposite sides of the heat exchange tubes 22. A first base 21 is connected to the upper cover 1, and a second base 23 is connected to the lower cover 3. Both the first base 21 and the second base 23 are provided with protruding locking blocks 24. The upper cover 1 and the lower cover 3 are respectively provided with fastening parts 4. The fastening parts 4 and the locking blocks 24 cooperate to fix the heat exchange body 2 to the upper cover 1 and the lower cover 3. This reduces the original molding process, facilitating production. Furthermore, it can be adapted to other heat exchange bodies 2, requiring only fixation to the base. Preferably, the base is provided with a plurality of insertion holes, and the heat exchange tube 22 is located in the insertion holes, so the number of heat exchange tubes 22 can be arbitrarily adjusted.

The upper cover 1 is provided with a first recess 11 adapted to the first protrusion 25, and the lower cover 3 is provided with a second recess 31 adapted to the second protrusion 26. Thus, the interplay between the protrusion and the recess allows for a tighter connection between the upper cover 1, the base, and the lower cover 3.

[0025] The upper cover 1, the lower cover 3, and the heat exchange tube 22 are all hollow and interconnected. The lower cover 3 has an air inlet 32 ​​and an air outlet 33. External gas enters the lower cover 3 through the air inlet 32, flows into the upper cover 1 along the heat exchange tube 22, then flows back into the lower cover 3 from the heat exchange tube 22 and is discharged from the air outlet 33. In the extending direction of the heat exchange tube 22, the height of the air inlet 32 ​​is higher than the height of the air outlet 33.

[0026] Preferably, the heat exchange tube 22 includes a riser tube 221 and a sinker tube 222 located on the left and right sides respectively. The second base 23 is also provided with a partition plate 5 connected to the lower cover 3. The partition plate 5 divides the air chamber in the lower cover 3 into a first air chamber 34 and a second air chamber 35.

In this way, the airflow path is standardized and mixing is avoided.

[0027] The lower cover 3 has interconnected engaging grooves 36 on opposite sides. The partition plate 5 is engaged and confined within the engaging grooves 36, which are located between the air inlet 32 ​​and the air outlet 33. In this embodiment, the engaging grooves 36 are designed to meander.

[0028] The bottom of the lower cover 3 is also provided with a first water outlet 37 and a second water outlet 38, and the locking groove 36 is located between the first water outlet 37 and the second water outlet 38. The first water outlet 37 and the second water outlet 38 are used to receive and discharge the condensate that flows back after passing through the heat exchange tube 22.

[0029] Preferably, the number of riser pipes 221 is less than the number of sinker pipes 222, and the diameter of the riser pipes 221 is greater than the diameter of the sinker pipes 222. This maximizes heat exchange efficiency.

[0030] In summary, the heat exchanger 100 for a dehumidifier of this utility model comprises a detachably connected upper cover 1, a heat exchange body 2, and a lower cover 3. The heat exchange body 2 includes a base and a plurality of heat exchange tubes 22 disposed on the base. Two bases are provided, located on opposite sides of the heat exchange tubes 22. A first base 21 is connected to the upper cover 1, and a second base 23 is connected to the lower cover 3. Both the first base 21 and the second base 23 are provided with protruding locking blocks 24. The upper cover 1 and the lower cover 3 are respectively provided with fastening parts 4. The fastening parts 4 and the locking blocks 24 cooperate to fix the heat exchange body 2 to the upper cover 1 and the lower cover 3. This reduces the molding process, facilitating production. Furthermore, it can be adapted to other heat exchange bodies 2, requiring only the fixation to the base.
