The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a charging pile fast heat dissipation distribution cabinet of the utility model includes a cabinet body 1 and a cabinet door 2, a panel 7 is installed inside the cabinet body 1, an air inlet cavity is formed between the back of the panel 7 and the cabinet body 1, a plurality of air outlets 5 are provided on the surface of the panel 7, a plurality of heat insulation blocks 8 are installed horizontally in front of the panel 7, and the heat insulation blocks 8 are provided with mounting ports 9 for fixing electrical components opposite to the air outlets 5, the cabinet door 2 is installed in front of the cabinet body 1, and the opening in front of the cabinet body 1 is sealed by the cabinet door 2, a shell body 4 is installed on the inner side surface of the cabinet door 2, an air outlet cavity 6 is formed between the shell body 4 and the cabinet door 2, the outer side surface of the shell body 4 is in contact with the end surface of the heat insulation block 8, the shell body 4 is provided with air inlets 15 opposite to the mounting ports 9, and an exhaust port 3 connected to the air outlet cavity 6 is provided on the bottom surface of the cabinet door 2.

[0023] In this embodiment, the top and bottom surfaces of the heat insulating block 8 are provided with rectangular openings at positions corresponding to the mounting opening 9, and spring pieces 11 are provided in the rectangular openings, one end of the spring pieces 11 is installed on one end of the rectangular openings, and an extrusion block 12 is installed on the inner side surface of the spring piece 11, and one end of the extrusion block 12 extends through the rectangular opening to the inside of the mounting opening 9, and a positioning frame 13 for pressing the spring piece 11 inward is provided on the outside of the heat insulating block 8;

[0024] The size of the mounting openings on each insulation block is the same, but the sizes of the mounting openings on different insulation blocks are different, so as to adapt to different electrical components.

[0025] In this embodiment, the inner side surface of the positioning frame 13 contacts the outer side surface of the heat insulation block 8 and the outer side surface of the spring sheet 11 , and a plurality of compression springs 14 are installed between the positioning frame 13 and the panel 7 .

[0026] In this embodiment, the spring sheet 11 is a metal spring sheet 11 , and the extrusion block 12 is made of insulating plastic material, so that the spring sheet has good elasticity.

[0027] In this embodiment, an air intake pipe 16 connected to the air intake cavity is installed on the back of the cabinet 1, a fan is installed in the middle of the air intake pipe 16, and a filter 17 is installed in the opening on the outside of the air intake pipe 16. The filter can filter out dust in the incoming air, thereby preventing dust from entering the interior of the cabinet.

[0028] In this embodiment, the heat insulating block 8 is made of polyester fiberboard, which has good heat insulating and fireproof properties and is relatively light and easy to install.

[0029] When installing, first push the positioning frame toward the panel. After the positioning frame moves away from the outer side of the spring sheet, the spring sheet tilts upward due to its own elasticity, thereby driving the extrusion block to move out of the installation opening, and the electrical component can be directly placed in the installation opening. After releasing the positioning frame, the rebound of the compression spring can drive the positioning frame to move to the outer side of the spring sheet again, so that the spring sheet bends inward. The movement of the spring sheet drives the extrusion block, and the extrusion block that moves inward can clamp and fix the electrical component. After clamping, a rectangular channel is formed between the electrical component and the installation opening.

[0030] After the above is completed, the cabinet door can be closed, and the movement of the cabinet door drives the shell until one side of the shell is against the end face of the insulation block. At this time, the air inlet, the installation port and the air outlet can be connected, and each electrical component can be separated by the insulation block to avoid the heat transfer between the electrical components. After starting the fan, the wind can directly pass through the air inlet, the installation port and the air outlet until it is discharged from the exhaust port. The channel formed by the air inlet, the installation port and the air outlet can increase the wind pressure and concentrate the wind, which can take away the heat from the electrical components more quickly to ensure the heat dissipation effect.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
