[0002] A power supply can provide stable voltage and current for various electrical equipment. The power supply design not only needs to consider the layout and performance of each component, but also needs to consider the later maintenance of the power supply. The electrical equipment can be a device capable of communicating and transmitting information, such as a transmitter capable of transmitting a signal from a sending end to a receiving end.

[0003] In the prior art, the power supply usually adopts an integral structure. When maintaining and replacing, the whole power supply needs to be disassembled and replaced, resulting in high maintenance costs. The integral power supply usually transfers the heat generated inside the integral power supply to the surface of the corresponding components through heat conduction, and then uses the air flow to take away the heat on the surface of the components. The surface area of the components is small, which affects the heat dissipation effect. Moreover, the components are vulnerable to electromagnetic interference and have poor electromagnetic compatibility.

[0004] That is, the power supply of the existing electrical equipment adopts an integral structure, which has the disadvantages of inconvenient and costly whole-machine replacement and maintenance, poor electromagnetic compatibility, and poor heat dissipation effect. Summary of the Utility Model

[0034] As Figures 1 to 4 shown, on the one hand, this embodiment provides a power supply device, which includes a housing and a power module. The housing includes an upper cover 12 and a lower housing 11. The upper cover 12 is detachably connected to the lower housing 11 and encloses a receiving space with the lower housing 11. The power module is arranged in the receiving space. The power module includes a functional component, a first housing 21 and an air-cooling component 30. The functional component is located between the lower housing 11 and the first housing 21 and is in contact with the first housing 21. The air-cooling component 30 is arranged on one side of the first housing 21 for heat dissipation.

[0035] By providing the detachable upper cover 12, the maintenance is convenient. Only need to remove the upper cover 12 and then repair the internal components of the power supply device, without replacing the whole power supply device, which reduces the maintenance cost. By arranging the first housing 21 outside the functional component and making the functional component in contact with the first housing 21, the heat generated in the functional component can be conducted from the surface of the component to the surface of the first housing 21. The air-cooling component 30 blows air towards the first housing 21, and the surface area of the first housing 21 is larger, thereby effectively improving the heat dissipation effect. By adding the first housing 21 outside the functional component, the functional component can be protected to reduce the electromagnetic interference in the environment during normal operation and improve the electromagnetic compatibility (EMC) of the power supply device.

[0036] In this embodiment, the lower housing 11 is in the form of a drawer, with an opening at the top and a bottom plate at the bottom. The upper cover 12 is covered on the lower housing 11 to close the top of the lower housing 11; the lower housing 11 extends in the first direction, and a front panel and a rear panel are oppositely arranged at both ends; the lower housing 11 and the upper cover 12 are made of metal materials, so as to play a role in protecting and supporting the power module. Optionally, the upper cover 12 and the lower housing 11 are fixedly connected by screws.

[0037] For the convenience of maintenance and repair, this embodiment adopts a modular design, dividing the internal components of the power supply device into a functional component, a terminal component and an air-cooling component 30.

By arranging the detachable first housing 21 on the first circuit board, while improving the heat dissipation effect, it does not affect the maintenance and replacement inside the battery device. When maintaining and replacing, the first housing 21 can be removed to check the functional component. By setting the first housing 21 to be U-shaped, an installation space is formed between the first housing 21 and the lower housing 11 to arrange the functional component.

To improve the heat dissipation effect of the terminal assembly, the power supply module further includes a second housing 22. The second housing 22 and the first housing 21 are located on the same side of the air-cooling assembly 30. The terminal assembly is disposed between the second housing 22 and the lower housing 11 and is in contact with the second housing 22. By providing the second housing 22, with the first housing 21 and the second housing 22 located on the same side of the air-cooling assembly 30, the heat generated by the terminal assembly is conducted to the surface of the second housing 22, and the air-cooling assembly 30 can blow air to the second housing 22.

By separately providing the detachable mounting plate 111, the setting position of the mounting plate 111 can be adjusted, and it is convenient for disassembly and replacement.

[0045] Preferably, the mounting plate 111 is parallel to the inner side wall of the lower housing 11 and is disposed at a first preset distance interval. The air-cooling assembly 30 is detachably disposed on the mounting plate 111 and is located between the mounting plate 111 and the inner side wall of the lower housing 11.
