[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The embodiment of the present application discloses a solar charging controller with a heat dissipation structure. Figure 1 and Figure 2 The solar charge controller with a heat dissipation structure includes a solar charge controller body 1, a base plate 2 detachably connected to the bottom surface of the housing of the solar charge controller body 1, a cooling fan 3 detachably connected to the base plate 2, and a locking assembly disposed within the base plate 2 for locking the cooling fan 3. The base plate 2 has a mounting opening 21 extending vertically through the base plate 2, and a locking groove 31 is provided on the side surface of the housing of the cooling fan 3. When the cooling fan 3 is placed on the mounting opening 21 of the base plate 2, the locking end of the locking assembly corresponds to the locking groove 31. The adjusting end of the locking assembly is rotated so that the locking end of the locking assembly engages with the locking groove 31, thereby locking the cooling fan 3 to the mounting opening 21 of the base plate 2.
[0033] An opening is provided on the bottom surface of the shell of the solar charge controller body 1, and the bottom plate 2 covers the opening. By starting the cooling fan 3, the cooling fan 3 discharges the heat generated inside the shell of the solar charge controller body 1 to achieve the effect of cooling the solar charge controller body 1, thereby improving the heat dissipation effect and ensuring that the cooling fan 3 is securely fixed.
[0034] Fixing members 22 are provided at each of the four corners of the bottom surface of the base plate 2. The fixing members 22 are threadedly connected to the housing of the solar charge controller body 1, thereby covering the base plate 2 over the housing opening of the solar charge controller body 1. In this embodiment, the fixing members 22 are fixing bolts that pass through the base plate 2 and are threadedly connected to the housing of the solar charge controller body 1.
[0035] In order to limit the cooling fan 3 located in the installation opening 21, a limiting frame 23 is fixedly connected to the installation opening 21 of the base plate 2. The top surface of the limiting frame 23 is flush with the top surface of the base plate 2, and the bottom surface of the limiting frame 23 abuts against the top surface of the outer shell of the cooling fan 3 to limit the cooling fan 3 located in the installation opening 21; and the bottom surface of the outer shell of the cooling fan 3 is flush with the bottom surface of the base plate 2.
[0036] Reference Figure 2-4The locking assembly includes a threaded rod 4 rotatably connected to the interior of the base plate 2, and a locking block 5 disposed within the base plate 2 and threadedly connected to the threaded rod 4. The base plate 2 defines a receiving cavity 24, within which the locking block 5 is located. A slider 51 is fixedly connected to the side of the locking block 5. A slot 25 corresponding to the position of the slider 51 is defined within the base plate 2. The slot 25 communicates with the receiving cavity 24, and the slider 51 is slidably connected to the slot 25. The length of the threaded rod 4 coincides with the length of the base plate 2. The end of the locking block 5 distal to the threaded rod 4 extends through the receiving cavity 24 and into the mounting opening 21. The end of the locking block 5 extending into the mounting opening 21 engages with the locking groove 31.
[0037] To ensure smooth sliding of the locking block 5 within the accommodating cavity 24, the same locking block 5 is provided with two sliders 51, symmetrically positioned on either side of the locking block 5. The number of slide grooves 25 matches the number of sliders 51, and they correspond one-to-one. The end of the threaded rod 4, away from the locking block 5, is flush with the end surface of the base plate 2. A polygonal groove 41 is defined at the end away from the locking block 5 to facilitate rotation of the threaded rod 4 using a tool. The locking block 5 is positioned below the retaining frame 23, and the threaded rod 4 is positioned between the four fixing members 22.
[0038] To more securely lock the cooling fan 3 into the mounting opening 21, two sets of locking assemblies are provided, symmetrically arranged within the base plate 2. To facilitate installation of the solar charge controller body 1 in the desired location, mounting tabs 11 are fixedly attached to both sides of the housing. These tabs 11 have two vertically aligned mounting holes, which facilitate installation of the solar charge controller body 1 in the desired location. When installing the solar charge controller body 1 in the desired location, ensure that the base plate 2 is facing downward.
[0039] The implementation principle of a solar charge controller with a heat dissipation structure in the embodiment of the present application is as follows: the device realizes the heat dissipation function by activating the heat dissipation fan 3, which dissipates the heat generated inside the housing of the solar charge controller body 1. During installation, the heat dissipation fan 3 is placed in the installation opening 21, and the threaded rod 4 is rotated by the adjustment end of the locking assembly to push the locking block 5 along the slide groove 25 until the locking block 5 engages with the locking groove 31 on the housing of the heat dissipation fan 3, thereby locking the heat dissipation fan 3 at the installation opening 21 of the base plate 2. The limit frame 23 abuts the top surface of the housing of the heat dissipation fan 3, further increasing the stability of the structure.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
