Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology, and in particular to a drive board junction box for preventing condensation. Background Technology

[0002] The circulating water pump that accompanies the heat pump is a key component. It pumps liquid for the exchange of heat or cold source of the heat pump. Since the heat pump is a dual-purpose device for hot and cold water, the water pump will encounter alternating hot and cold water, producing a large amount of condensate that corrodes the circuit board.

[0003] Most drives are WW (Wireless Wire) and require aluminum heat sinks for heat dissipation. Because they also contain operation buttons and a display interface, a complete encapsulation is not feasible to ensure the proper functioning of these components. Currently, the common approach is to seal the circuit board, aluminum casing, and junction box housing. However, condensation still occurs within this sealed cavity, and the circuit board corrodes quickly as the sealant ages. This is especially problematic when encapsulating the motherboard, as the display board terminals and power motor terminals remain exposed to the air and are susceptible to corrosion from condensation, leading to a high rate of user malfunctions. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a driver board junction box for preventing condensation. By adding a plastic part between the panel display area of ​​the driver board and the aluminum shell, and setting a sealing ring on the plastic part, a sealed isolation is formed between the aluminum shell and the panel display area. During the potting process, the entire panel display area is sealed, which can realize the overall potting of the driver board while effectively preventing condensation from damaging the circuit board.

[0005] This utility model provides a drive board junction box for preventing condensation, including an aluminum shell (10) and a junction box housing (20). The aluminum shell (10) is used to house the drive board. A display window (11) is provided on the aluminum shell (10) for displaying the panel display area of ​​the drive board.

The first sealing element (211) and the second sealing element (221) are used to form a sealed isolation for the panel display area.

[0006] In one embodiment, the first seal (211) includes, but is not limited to, a Mylar sheet or a groove for placing a rubber ring.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 As shown, Figure 1 This is a structural schematic diagram of the drive board junction box for preventing condensation provided by this utility model. Figure 1It is known that the drive board junction box for preventing condensation includes an aluminum shell (10) and a junction box housing. The aluminum shell (10) is used to house the drive board. The junction box housing is not shown in the figure. The junction box housing is detachably connected to the aluminum shell to form the drive board junction box. A display window (11) is provided on the aluminum shell (10) for displaying the panel display area of ​​the drive board. A plastic pad (20) is provided between the display window (11) and the panel display area.

[0022] Please see Figure 2 and Figure 3 As shown, Figure 2 A schematic diagram of the first surface structure of the plastic pad provided by this utility model. Figure 3 This is a schematic diagram of the second surface structure of the plastic pad provided by this utility model. Figure 2 It can be seen that the first surface (21) of the plastic pad (20) is provided with a first sealing member (211) corresponding to the edge of the display window (11), by Figure 2 It is understood that the second surface (22) of the plastic pad (20) is provided with a second sealing element (221) corresponding to the edge of the panel display area. Both the first sealing element (211) and the second sealing element (221) contain rubber rings to form a sealed isolation for the panel display area. The first sealing element (211) includes, but is not limited to, a Mylar sheet or a rubber ring groove containing a rubber ring. The second sealing element (221) includes a rubber ring groove containing a rubber ring. It should be noted that this application does not limit the first sealing element (221) and the second sealing element (221). They can be any sealing and insulating element other than a Mylar sheet or a rubber ring groove containing a rubber ring, as long as they belong to the category of sealing and insulating elements and can achieve the above functions.

[0023] For example, such as Figure 4 As shown, when the plastic pad (20) is placed between the aluminum shell (10) and the drive board, the panel display area below the plastic pad (20) can be clearly seen through the display window (11) on the surface of the aluminum shell (10). Furthermore, by setting indicator grooves on the second surface of the plastic pad (20) that match the buttons or parameters of the panel display area, users can easily perform button operations or parameter readings through the plastic pad (20).

[0024] In this application, the aluminum shell (10) is used to house the driver board and also serves to dissipate heat. The junction box housing is responsible for the outer shell structure and protects the internal components. The display window (11) is set on the aluminum shell (10) and is used to display the panel display area of ​​the driver board. The display window (11) provides a visual interface, allowing users to view the working status of the driver board or operate some operation buttons.

[0025] A plastic gasket (20) is provided between the display window (11) and the panel display area of ​​the driver board, which serves as a sealing component. Specifically, the first surface (21) of the plastic gasket (20) corresponds to the edge of the display window and is provided with a first sealing element (211) to form a sealing effect. The second surface (22) corresponds to the edge of the panel display area and is provided with a second sealing element (221) to seal the panel display area. Through this design, the plastic gasket (20) and the rubber ring work together to form an upper and lower sealing isolation between the aluminum shell (10) and the panel display area, thereby effectively preventing condensate from entering the junction box and protecting the circuit from condensate damage.

[0026] In this structure, the sealing design of the plastic pad (20) ensures that the panel display area is completely sealed during the potting operation, preventing the potting adhesive from seeping into the display area, thereby protecting the function and appearance of the display area, while achieving overall potting of the drive board.

[0027] In one embodiment, the drive board is provided with heat dissipation holes to dissipate heat to the aluminum shell (10). The heat dissipation holes on the drive board dissipate the generated heat into the aluminum shell, preventing excessive temperature from affecting the drive board and ensuring stable operation of the equipment. Specifically, this application embodiment does not impose any limitations on the structure of the drive board itself.

[0028] In one embodiment, the plastic gasket (20) comprises gray silicone. The plastic gasket (20) uses gray silicone material, which has good elasticity and water resistance, contributing to improved sealing performance and service life.

[0029] In one embodiment, the panel display area is coated with a waterproof material. Applying the waterproof material enhances the waterproof performance.

[0030] In one embodiment, the panel display area includes a button operation area and a parameter display area. It should be noted that this application does not impose any limitations on the button operation area and the parameter display area.

[0031] The beneficial effects of this invention are as follows: By adding a plastic component between the panel display area of ​​the driver board and the aluminum shell, and setting a sealing ring on the plastic component, a sealed isolation is formed between the aluminum shell and the panel display area. This achieves complete sealing of the panel display area during the potting process, effectively preventing condensate from entering the junction box and damaging the circuit board while simultaneously potting the entire driver board. This improves the user experience.
