However, there is a lack of coordinated airflow organization between the heat dissipation modules, and the heat dissipation channels of each layer are independent of each other, resulting in serious heat backflow between modules. In view of this, a programmable DC power supply heat dissipation module was designed. Utility Model Content

Detailed Implementation
[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0032] like Figures 1-3 As shown, a programmable DC power supply heat dissipation module includes a housing 1, with multiple fan assemblies 2 symmetrically arranged on the upper and lower ends of one side of the housing 1, and an air outlet 3 opened on the other side of the housing 1.
[0033] like Figure 4 and Figure 5 As shown, a heat dissipation substrate 4 is fixedly connected to the middle of the inner cavity of the outer shell 1. The main power component with the largest heat generation can be installed on the heat dissipation substrate 4, and the heat generated by the power devices in the programmable DC power supply can be conducted to the heat dissipation fins 5 through the heat dissipation substrate 4.
[0034] The heat dissipation substrate 4 is made of C11000 electrolytic copper plate. The main power part with the largest heat generation is installed on the copper heat dissipation substrate 4, and the high thermal conductivity of copper is used to conduct heat quickly.
[0035] Multiple sets of heat dissipation fins 5 are arranged at the bottom of the heat dissipation base plate 4. The heat dissipation fins 5 extend along the air outlet direction of the fan assembly 2. With the heat dissipation fins 5 extending along the air outlet direction of the fan assembly 2, and in conjunction with the symmetrical fan assemblies 2 and air outlets 3 on both sides of the outer shell 1, a directional airflow channel is formed. After entering from the fan assembly 2, the cool air flows directionally along the top of the heat dissipation fins 5 and the heat dissipation base plate 4, effectively carrying away heat and expelling it through the air outlets 3, forming an efficient convection circulation. This solves the problem of uneven heat dissipation caused by heat backflow between traditional layered heat dissipation modules.
[0036] In some embodiments, such as Figure 7 As shown, a dustproof component 11 is detachably connected to the inner side of the air outlet 3. The dustproof component 11 includes a square frame 1101, and a second dustproof mesh 1102 is fixedly connected inside the square frame 1101. The second dustproof mesh 1102 is detachably connected to the inner side of the air outlet 3. The square frame 1101 has multiple fixing holes, and a magnet 1103 is fixedly connected inside the fixing holes. The magnet 1103 is magnetically attracted to the outer shell 1. The dustproof component 11 adopts a detachable connection between the square frame 1101 and the second dustproof mesh 1102, and uses the magnet 1103 to achieve magnetic attraction and fixation. While ensuring the dustproof effect, it also realizes the quick and non-destructive assembly and disassembly of the dustproof component 11.
[0037] In some embodiments, such as Figure 5 and Figure 6 As shown, the fan assembly 2 includes a mounting frame 21, a fixing bracket 22, and a cooling fan 23. The mounting frame 21 is embedded in the through hole of the outer casing 1, the fixing bracket 22 is fixed inside the mounting frame 21, and the cooling fan 23 is fixed inside the fixing bracket 22. A first dustproof mesh 24 is fixedly connected inside the mounting frame 21, and the first dustproof mesh 24 is located on the air intake side of the cooling fan 23. The first dustproof mesh 24 can effectively block dust, hair, and other foreign objects from entering the programmable DC power supply, protecting the internal components of the programmable DC power supply from contamination and avoiding a decrease in heat dissipation efficiency due to dust accumulation.
[0038] In some embodiments, such as Figure 4 As shown, the heat dissipation fin 5 includes a first heat dissipation fin 6, the cross-section of which is an isosceles trapezoid. The isosceles trapezoid design increases the heat dissipation area, optimizes airflow, and reduces wind resistance. A second heat dissipation fin 7 is fixedly connected to both sides of the first heat dissipation fin 6. The second heat dissipation fin 7 is rectangular. The rectangular second heat dissipation fin 7 further expands the heat dissipation surface and improves heat exchange efficiency.
[0039] In some embodiments, the first heat sink 6 and the second heat sink 7 are made of AL606 aluminum alloy and are anodized. A thermally conductive coating of boron nitride particles with a thickness of about 20-50 μm is sprayed on the surface of the first heat sink 6 and the second heat sink 7 to improve thermal conductivity while taking into account corrosion resistance, lightweight and ease of maintenance.
[0040] In some embodiments, such as Figures 1-3 As shown, a panel 8 is fixedly connected to the front of the outer casing 1. The panel 8 provides an operation interface, which is convenient for users to set parameters and monitor status. Pull handles 9 are fixedly connected to both sides of the panel 8. The pull handles 9 are designed to facilitate the handling and installation of the programmable DC power supply.
[0041] In some embodiments, such as Figure 3 As shown, a mounting bracket 10 is fixedly connected to the top of the inner wall of the housing 1, and mounting holes are provided on the surface of the mounting bracket 10. Components can be installed in layers as needed. For example, the main power component with the highest heat generation can be installed on the heat dissipation substrate 4, and the main power component with the next highest heat generation can be installed at the bottom of the inner cavity of the housing 1. The control and communication components are installed on the mounting bracket 10. This allows for layered heat dissipation, avoids heat concentration, and improves heat dissipation efficiency.
