[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides an embodiment: a heat dissipation mechanism for an electrical control cabinet, comprising:

[0025] The heat dissipation component 1 comprises a positioning cylinder 11, the inner wall of the positioning cylinder 11 is provided with a card slot 12, a motor frame 13 is plugged into the interior of the positioning cylinder 11, a card buckle 14 is provided on the outer wall of the motor frame 13, a heat dissipation fan 15 is connected to the interior of the motor frame 13, a guide shaft 16 is plugged into one end of the motor frame 13, a tension spring 17 is sleeved on the outer side of the guide shaft 16, and an extrusion ring 18 is connected to the other end of the guide shaft 16. Through the setting of this structure, the quick installation and positioning of the motor frame 13 is completed by the cooperation of the card slot 12 and the plug-in knob of the card buckle 14, thereby improving the convenience of disassembly and assembly of the internal heat dissipation fan 15, facilitating the subsequent inspection and maintenance of the heat dissipation fan 15, and at the same time, the elastic extrusion of the extrusion ring 18 is cooperated to further improve the stability of the plug-in limit of the motor frame 13;

[0026] The heat dissipation net 3 is located at the end of the extrusion ring 18 away from the guide shaft 16. By placing the heat dissipation net 3 and coordinating the extrusion of the motor frame 13 and the extrusion ring 18, the heat dissipation net 3 can be quickly installed, thereby achieving safe protection for the heat dissipation component 1 and reducing the entry of external dust and impurities. At the same time, its quick-release structure facilitates subsequent disassembly and cleaning.

[0027] Furthermore, it also includes a cabinet 2, the outer wall of the positioning cylinder 11 is integrally formed with a positioning flange, and the positioning flange is fixedly connected to the inner wall of the cabinet 2 by bolts, and heat dissipation holes are opened on the cabinet 2 corresponding to the positioning cylinder 11. Compared with the traditional integrated heat dissipation hole mechanism, the mutual cooperation of the heat dissipation net 3 and the heat dissipation holes can achieve impurity isolation and ventilation, and disassembly and assembly are quick and convenient.

[0028] Furthermore, the diameter of the heat dissipation net 3 is larger than the diameter of the heat dissipation hole of the cabinet 2, the diameter of the heat dissipation net 3 is equal to the inner diameter of the positioning tube 11, the diameter of the heat dissipation net 3 is equal to the outer diameter of the extrusion ring 18, the slot 12 and the buckle 14 are both provided with five groups, the slot 12 is an L-shaped structure, and the outside of the buckle 14 is wrapped with a soft rubber pad. Through the wrapping of the soft rubber pad, the extrusion effect with the inner wall of the slot 12 can be improved, and the stability of its engagement can be further improved.

[0029] Furthermore, a through hole is provided on one side of the motor frame 13 close to the extrusion ring 18, and a guide shaft 16 is slidably inserted inside the through hole. The guide shaft 16 is in a step shape. The inner wall of the through hole of the motor frame 13 is fixedly connected with a guide ring, and the guide ring is slidably connected to the guide shaft 16. A tension spring 17 is hung between the step-shaped guide shaft 16 and the guide ring. The inner diameter of the extrusion ring 18 is equal to the inner diameter of the motor frame 13. A silicone pad is provided on one side of the extrusion ring 18 close to the heat dissipation network 3. Through the provision of the silicone pad, the contact stability with the heat dissipation network 3 is improved, and the metal contact is reduced, thereby further improving the noise reduction effect. The extrusion ring 18 is elastically pulled by the tension spring 17, so that when it is installed under pressure, the tension spring 17 will be pulled, and then the buckle 14 knob is rotated to the inside of the slot 12. At this time, the tension spring 17 is pulled back by its own elastic force, so that the guide shaft 16 and the extrusion ring 18 squeeze the heat dissipation network 3 while ensuring the stability of the installation of the motor frame 13.

[0030] Working principle: The cabinet 2 and the cooling fan 15 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the heat dissipation net 3 is first placed inside the positioning tube 11, and the buckle 14 is further plugged into the corresponding slot 12, and the motor frame 13 is pressed so that the buckle 14 can be rotated to the inside of the slot 12. At this time, the extrusion ring 18 is affected by the elastic force to squeeze and position the heat dissipation net 3, thereby completing the rapid positioning of the motor frame 13 and the heat dissipation net 3.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
