Description

[Technical Field]

[0001] This utility model mainly relates to a dehumidifier core fixing structure. [Background Technology]

[0002] Electronic semiconductors, camera lenses, and other devices have stringent requirements regarding the humidity of the storage environment. Excessive humidity can easily damage these devices, causing significant losses. Therefore, special desiccant boxes are needed to store these devices. The main component of such a desiccant box is the dehumidifier core, which works by condensing moisture in the air into water droplets, which are then absorbed by the cotton wick.

[0003] A dehumidifier core typically includes a condensate coil, an electronic cooling element, and a deflector plate. Currently, the deflector plate and condensate coil are installed by tightening their respective screws, requiring two alignment steps, which is inefficient. To accelerate installation, we propose a new assembly structure to improve production efficiency. [Utility Model Content]

Detailed Implementation Methods

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] The preferred embodiment provided by this utility model is as follows: Figures 1-3 As shown, a dehumidifier core fixing structure includes a heat sink 1, a condenser 2, an electronic cooling chip 3, a guide plate 4, and a fixing base 5. The heat sink 1 has an assembly area 11, which has a socket 12 and a first screw hole 13. The guide plate 4 has a post 41, which is inserted into the socket 12 for assembly on the heat sink 1. The guide plate 4 also has an adhesive layer (not shown in the figure, the adhesive layer uses existing waterproof glue) to stick and fix the guide plate 4 to the assembly area 11.

[0024] The guide plate 4 has a cavity 42, the front end of which is open; the fixing seat 5 is installed on both sides of the condenser 2, and the fixing seat 5 and the condenser 2 partially extend into the cavity 42; the fixing seat 5 is provided with a second screw hole 51, and the heat sink 1 is connected to the fixing seat 5 so that the second screw hole 51 is matched with the first screw hole 13; the fixing seat 5 is provided with a screw, which passes through both the first screw hole 13 and the second screw hole 51 to lock the fixing seat 5 to the heat sink 1;

[0025] An electronic cooling chip 3 is placed in assembly area 11 and is connected to the condenser 2 to be pressed against the heat sink 1 by the condenser 2. The electronic cooling chip 3 is connected to a circuit board 6, which is located within assembly area 11 and is secured to the heat sink 1 with screws. Assembly area 11 has a guide hole 14, which communicates with the cavity 42 of the guide plate 4 fixed to the heat sink 1, allowing condensate in the cavity 42 to be drained through the guide hole 14. The heat sink 1 is fitted with a protective shell 7, which is locked to assembly area 11 to cover the components and provide protection.

[0026] The inner wall of the cavity 42 is provided with protrusions 43, which are located on both sides of the cavity 42 and at the front end of the cavity 42, facilitating the engagement of the fixing seat 5. The fixing seat 5 is provided with a snap-fit ​​52, the top of which is open. The protrusions 43 enter from the open top of the snap-fit ​​52 and engage with the snap-fit ​​52 to assemble the guide plate 4 and the fixing seat 5 together, restricting the relative movement between the fixing seat 5 and the guide plate 4. When the insert post 41 of the guide plate is inserted into the insertion hole 12, the second screw hole 51 will also accurately correspond to the first screw hole 13, facilitating the simultaneous insertion of screws into the first screw hole 13 and the second screw hole 51. The snap-fit ​​52 is located on the outer side of the fixing seat 5, and the inner side of the fixing seat 5 is provided with a slot 53 for the condensate component 2 to be inserted.

[0027] The condenser 2 includes a flat plate body 21 and guide vanes 22. The end of the flat plate body 21 is connected to a slot 53, and the fixing base 5 is installed at both ends of the flat plate body 21. The flat plate body 21 is in close contact with the electronic cooling chip 3. The guide vanes 22 are arranged vertically and parallel on the end face of the flat plate body 21. The condenser 2 is preferably made of aluminum profile because aluminum profile is lightweight and has good thermal conductivity, which effectively improves the cooling efficiency. Moreover, selecting aluminum profile of suitable material or coating the surface of aluminum profile with a water-repellent coating can improve the flow guiding performance of the condenser 2 and prevent water droplets from accumulating and freezing. The condenser 2 has a funnel-shaped guide plate 4 at its bottom. The lowest end of the guide plate 4 is directly opposite the guide hole 14. The guide plate 4 and the back of the heat sink together enclose a funnel-shaped cavity 42. The open front end of the cavity 42 is directly opposite the condenser 2.

[0028] A dehumidifier core typically includes a condenser 2, an electronic cooling element 3, and a deflector plate 4. Currently, the deflector plate 4 and condenser 2 are installed by tightening their respective screws. Since screw installation requires hole alignment, the installation of the deflector plate 4 and condenser 2 requires matching the holes twice. To reduce the number of alignment attempts, this invention proposes a dehumidifier core fixing structure. During assembly, the electronic cooling element 3 is first placed in the assembly area 11, and the fixing base 5 is respectively embedded on both sides of the condenser 2. The protrusion 43 connects with the bayonet 52 to assemble the deflector plate 4, fixing base 5, and condenser 2 into a whole. At this point, the positions of the insertion post 41 and the second screw hole 51 are relatively fixed. Inserting the insertion post 41 into the insertion hole 12 aligns the second screw hole 51 with the first screw hole 13, eliminating the need for multiple alignment attempts. This is very convenient and quick, significantly improving production efficiency.
