[0016] The embodiments of this application are described in detail below. These embodiments are implemented based on the technical solutions of this application and provide detailed implementation methods and specific operation processes. However, the protection scope of this application is not limited to the following embodiments.
[0017] Please refer to Figures 1 to 2 As shown, this application document is implemented through the following technical solution: This application document discloses a switching power supply with shielding function, including a shell 1, the shell including a first cavity, the top of the first cavity being in communication with the external environment, the first cavity being divided into three sub-spaces 11 by a partition member 2, the sub-spaces 11 being arranged in a row, and respectively placing a power supply member, a filter member and an electronic device, the power supply member and the electronic device being in communication, the first cavity being sealed by a cover member, the side of the cover member 3 closest to the first cavity being arranged as the first side, the first side corresponding to each sub-space being arranged with a temperature detection device 4, the side of the cover member 3 away from the first cavity corresponding to each sub-space 11 being arranged with a warning member, the temperature detection device being connected to the warning member.
[0018] Specifically, the outer casing 1 has a first cavity inside, and the top of the first cavity is in communication with the external environment to facilitate the installation of the cover component and the maintenance of the internal components. The outer casing is made of metal. The first cavity is divided into three sub-spaces 11 by a partition component. The three sub-spaces 11 are arranged in a row, and each sub-space houses a power supply component, a filter component, and electronic components, with the power supply component and electronic components in communication. The power supply component outputs a stable voltage and current to power external devices. The filter component filters the electrical energy output by the power supply, removing noise and interference signals. The electronic components include control circuits and protection circuits, used to implement the control and protection functions of the switching power supply. The cover component 3 is used to seal the first cavity to prevent dust, moisture, and other external impurities from entering the power supply and affecting its normal operation. The side of the cover component closest to the first cavity is designated as the first side, and temperature detection devices are arranged on the first side corresponding to each sub-space. In one embodiment, the temperature detection device is a thermistor. The temperature detection device can monitor the temperature changes inside each subspace in real time. On the side of the cover component away from the first cavity, a warning component is arranged for each subspace. When the temperature detection device detects that the temperature of a certain subspace exceeds a preset safety threshold (e.g., 80°C), it will trigger the corresponding warning component to emit an audible and visual alarm signal to prompt the user that there is an abnormal temperature in the subspace.
[0019] In one embodiment, the warning component includes an LED indicator and / or a buzzer.
[0020] In one embodiment, the outer casing is made of aluminum alloy, which has good thermal conductivity, enabling it to quickly conduct heat generated inside the power supply, thus helping to reduce the internal temperature and ensuring that each component operates in a suitable temperature environment. Each sub-space has heat dissipation holes at its bottom, providing a direct channel for heat dissipation. In some embodiments, heat dissipation holes are also provided on the surface of the cover component corresponding to each sub-space, further increasing the heat dissipation pathways. When heat is conducted from inside the power supply to the outer casing surface, the heat dissipation holes on the cover component surface can accelerate the dissipation of heat to the external environment. To enhance heat dissipation, in one embodiment, a cooling fan is also arranged inside each sub-space. When the temperature is abnormal or the switching power supply is in operation, the cooling fan can actively dissipate heat to the relevant sub-space.
[0021] like Figure 3As shown, in one embodiment, the separating member 2 includes a first frame 21 and an absorbing layer 22. The first frame 21 forms an enclosing structure, and the inner wall of the first frame 21 is attached with an absorbing layer. Carbon nanotubes can effectively absorb electromagnetic waves and reduce the impact of electromagnetic interference on the internal components of the power supply. In one embodiment, the first frame 21 is made of glass fiber, and / or the absorbing layer is a carbon nanotube layer. Glass fiber has high strength and good thermal insulation performance. It is arranged in a cubic shape and connected to the outer shell by fasteners to form a stable enclosing structure, which accurately divides the first cavity into three independent subspaces 11. Thermal isolation is achieved through the first frame to prevent the high temperature caused by the failure of a device in one subspace from affecting the devices in other subspaces, ensuring that each device can operate in a relatively independent and stable environment.
[0022] In one embodiment, a handle is provided on the surface of the cover member away from the subspace. The cover member needs to be opened when it is necessary to inspect, repair, or replace components inside the power supply. The handle's location on the surface of the cover member away from the subspace allows the operator to easily apply force when opening or closing the cover member, avoiding potential inconvenience or damage to the cover member due to direct contact with its edge. During operation, the switching power supply may be affected by vibrations from internal components and the external environment. If placed directly on a flat surface, these vibrations may be transmitted through the casing to the surface, generating noise. By providing a support pad at the bottom of the casing to buffer these vibrations, noise generation is reduced. In one embodiment, the support pad is made of rubber or silicone.
[0023] In summary, the switching power supply disclosed in this application has three sub-spaces inside the casing, each housing different components, representing a reasonable layout of the power supply components. By installing temperature detection devices and warning components on the cover component, the components in each sub-space are monitored. When a component malfunctions, the temperature becomes abnormal. The corresponding temperature detection device and warning component can quickly identify the area with abnormal temperature, and then troubleshoot the power supply components in the corresponding area.
[0024] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
