In order to ensure that the electrical components inside the distribution box can operate stably, a heat dissipation structure needs to be set up to effectively dissipate the heat of the distribution box.

[0003] After searching, the patent number CN220492514U discloses a heat dissipation structure of a distribution box. The heat dissipation structure inside the distribution box moves the filter frame upward to drive the dovetail slider to move. After the dovetail slider moves out of the dovetail slide groove, the restriction on the filter frame can be released, which is convenient for replacing new desiccant and maintaining the drying effect of the device. At the same time, it is convenient to clean the dust accumulated on the surface of the filter to ensure smooth air circulation in the ventilation and heat dissipation holes.

[0004] However, when removing the filter and the desiccant from the above-mentioned distribution box, it is necessary to go deep into the distribution box to operate. Since many electrical components are arranged inside the distribution box, the space for removing the filter is small and complicated, which is not convenient for operation. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a heat dissipation structure of a distribution box.

[0026] The utility model provides Figure 1-3 A distribution box heat dissipation structure shown includes a distribution box body 1 and mounting holes opened on both sides of the distribution box body 1, a first filter frame 2 and a second filter frame 3 are arranged in the mounting hole, the first filter frame 2 and the second filter frame 3 are opened at one end close to each other, the first filter frame 2 and the second filter frame 3 are filled with desiccant 4, a guide connection mechanism is provided between the first filter frame 2 and the second filter frame 3 and the inner wall of the mounting hole, the guide connection mechanism includes a slide rod 6, the slide rod 6 is fixedly penetrated into the interior of the first filter frame 2, guide holes 7 are opened on both sides of the inner wall of the mounting hole, the end of the slide rod 6 is slidably arranged in the guide hole 7, the first filter frame 2 and the second filter frame 3 are fixedly provided with a rubber sealing ring 12 at one end close to each other, and the two rubber sealing rings 12 are in contact and fit.

[0027] When the distribution box 1 is in use, the first filter frame 2 and the second filter frame 3 are sealed and connected by the rubber sealing ring 12 and are arranged in the installation hole. At this time, the external airflow can enter the distribution box 1 through the filter frame. In this process, the desiccant 4 absorbs the water vapor in the air, so that the dry and pure gas can enter the distribution box 1 to effectively dissipate the heat of the electrical components, thereby improving the heat dissipation effect. When the desiccant 4 needs to be replaced, the first filter frame 2 and the second filter frame 3 can be rotated and the openings can be exposed under the sliding cooperation of the sliding rod 6 and the guide hole 7. At this time, the desiccant 4 can be pulled out and replaced without entering the distribution box 1 for operation, thereby increasing the operating space and improving the convenience of operation.

[0028] In order to be able to quickly separate the first filter frame 2 and the second filter frame 3 when the desiccant 4 is disassembled, as shown in FIG. Figure 2-3As shown, a movable groove and a positioning hole 5 are respectively provided at one end close to the first filter frame 2 and the second filter frame 3, and a plug-in positioning mechanism is provided between the movable groove and the positioning hole 5. The plug-in positioning mechanism includes a positioning tube 8. A support rod 9 is fixedly provided on the top of the inner wall of the movable groove. The positioning tube 8 is slidably sleeved on the outer side of the support rod 9. The lower end of the positioning tube 8 is plugged into the positioning hole 5. A spring 10 is sleeved on the rod wall of the support rod 9. Both ends of the spring 10 are fixedly connected to the support rod 9 and the positioning tube 8 respectively. A strip hole 13 is provided on the side of the movable groove. A push rod 11 is slidably penetrated inside the strip hole 13, and the push rod 11 is fixedly connected to the positioning tube 8.

[0029] When the first filter frame 2 and the second filter frame 3 are working normally, the positioning tube 8 is inserted into the positioning hole 5 to determine the positions of the first filter frame 2 and the second filter frame 3. When the desiccant 4 needs to be replaced, the push rod 11 is pushed to make the push rod 11 slide in the strip hole 13 and drive the positioning tube 8 to move upward. During this process, the positioning tube 8 is pulled out from the positioning hole 5 and slides along the support rod 9, while the spring 10 is squeezed. Then the first filter frame 2 and the second filter frame 3 can be rotated, and the internal desiccant 4 can be replaced.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
