Technical Field

[0001] The utility model relates to the technical field of heat dissipation of power supply devices, in particular to a power supply device with a heat dissipation protection function. Background Art

[0002] The plc expansion module is a module that is expanded because the number of modules on the CPU or power baseboard is limited and the number of modules or functions need to be increased. When in use, a heat sink needs to be installed on its surface to cool it down.

[0003] In the prior art, for example, Chinese patent CN203574994U discloses an overheat protection device and an electronic device with an overheat protection function. The overheat protection device is connected to the electronic device, and the overheat protection device includes a cooling fan, a driving module, and a temperature sensing element. When the temperature sensing element detects that the temperature of the electronic device is higher than a default temperature, the driving module stops supplying power to the cooling fan, so that the cooling fan is turned off. When the cooling fan is turned off and the driving module receives a fan feedback signal of a specific state from the cooling fan, the driving module stops supplying power to the electronic device to prevent the electronic device from burning.

[0004] However, in the prior art, the power supply device generates a lot of heat during operation. Currently, traditional cooling fans can only cool down a specific area, and the overall effective heat dissipation area is smaller than the actual area. Therefore, in actual use, there may be some areas that cannot be effectively cooled. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the traditional cooling fan can only cool a specific area, and some areas may not be effectively cooled, and to propose a power supply device with a heat dissipation protection function.

[0007] The heat dissipation device includes a protective frame, a partition frame, a fan body and an electric cylinder. The fan body is movably installed inside the partition frame. An adapter plate is fixedly connected to the top of the partition frame. A positioning protrusion is fixedly installed on one side of the adapter plate. One end of the electric cylinder lead screw is rotatably connected to the inside of the positioning protrusion. The other end of the electric cylinder is rotatably connected to the positioning plate. The other side of the partition frame is rotatably connected to the lower surface of the positioning plate. The positioning plate is fixedly installed on the lower surface of the protective frame. The fan body is located above the power supply device body.

[0008] Preferably, a filter is provided at the junction of the power supply device body and the protection frame, and the filter is located between the fan bodies.

[0009] Preferably, a docking protrusion is fixedly mounted on the inner wall of the protection frame, and the docking protrusion is slidably connected to the outer wall of the power supply device body.

[0010] Preferably, a limit plate is fixedly mounted on one end of the protection frame.

[0011] Preferably, a supporting protrusion is fixedly mounted at the junction of the positioning plate and the electric cylinder, and the bottom of the electric cylinder is rotatably connected to the inside of the supporting protrusion.

[0012] Preferably, a limit ring is fixedly installed at the intersection of the electric cylinder, the supporting protrusion and the positioning protrusion.

[0013] Preferably, the electric cylinder is located between the adapter plate and the positioning plate.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, the power supply device body is protected by a protective frame, and the fan body arranged inside can change its angle within a certain range under the support of the electric cylinder, thereby changing the direction of the airflow blown out by the fan body, so as to obtain a better heat dissipation effect, thereby avoiding the situation where some areas cannot be effectively cooled down. In addition, the protective frame itself can be moved, which further expands the effective heat dissipation area.

[0016] 2. In the utility model, the fan body is protected by a partition frame, and the specific position of each partition frame is determined by the connection between the adapter plate and the positioning plate, so as to ensure the overall structural stability.

The positioning plate 26 is fixedly installed on the lower surface of the protective frame 21. The fan body 28 is located above the power supply device body 1. A support protrusion 29 is fixedly installed at the junction of the positioning plate 26 and the electric cylinder 211. The bottom of the electric cylinder 211 is rotatably connected to the inside of the support protrusion 29. A limiting ring 212 is fixedly installed at the junction of the electric cylinder 211, the support protrusion 29 and the positioning protrusion 210. The electric cylinder 211 is located between the adapter plate 27 and the positioning plate 26.

[0028] The specific configuration and function of this embodiment are described in detail below. The heat dissipation device 2 is directly mounted on the outer wall of the power supply device body 1, and the power supply device body 1 is protected by a protective frame 21. When dissipating heat, the air is stirred to generate airflow by rotating the blades of the fan body 28, thereby accelerating the flow speed of the air inside the power supply device body 1 and achieving the purpose of heat dissipation. In the heat dissipation process, the electric cylinder 211 can be used to change the angle of the adapter plate 27. Since the fan body 28 is mounted in the partition frame 25, the rotation of the adapter plate 27 can change the air supply direction of the fan body 28, thereby ensuring that the heat dissipation device 2 can perform comprehensive heat dissipation treatment on the power supply device body 1.

[0029] The screw of the electric cylinder 211 is rotatably connected to the positioning protrusion 210 through a limit ring 212, and the bottom is rotatably connected to the support protrusion 29 through another limit ring 212.

A limiting plate 22 is fixedly installed at one end of the protective frame 21.

[0032] The effect achieved by the entire embodiment is that the filter 23 is mainly used to further separate the power supply device body 1 and the fan body 28, which can not only ensure that the airflow can enter the interior of the power supply device body 1, but also avoid the accessories inside the power supply device body 1 from contacting the fan body 28. The protective frame 21 itself is connected to the outer wall of the power supply device body 1 through the docking protrusion 24, and can be moved within a certain range, thereby further expanding the heat dissipation area.

[0033] The use method and working principle of the device: The filter 23 is used to separate the power supply device body 1 and the fan body 28, and ensure that the air flow can enter the interior of the power supply device body 1;

[0034] When in use, the fan body 28 rotates its blades to stir the air to generate airflow, thereby accelerating the flow speed of the air inside the power supply device body 1 to achieve the purpose of heat dissipation;

[0035] During the heat dissipation process, the screw rod in the electric cylinder 211 moves out to push the adapter plate 27 to rotate through the positioning protrusion 210, thereby changing the air supply direction of the fan body 28, ensuring that the heat dissipation device 2 can perform comprehensive heat dissipation treatment on the power supply device body 1. The other side of the adapter plate 27 is connected to the positioning plate 26, and the positioning plate 26 itself is fixed in the protection frame 21, so there will be no misalignment.

[0036] At the same time, the protection frame 21 can be moved within a certain range through the docking protrusions 24 to further expand the heat dissipation area.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
