Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a heat dissipation structure for a motor junction box. Background Technology

[0002] Motors generate a lot of heat when they are working. In order to dissipate the heat quickly and improve the stability of the motor during operation, heat dissipation fins are usually installed on the surface of the motor. A fan blows air along the heat dissipation fins to achieve heat dissipation. However, this kind of heat dissipation can only dissipate heat on the surface of the motor housing. There are usually no corresponding fins installed at the junction box of the motor. The heat at the junction box of the motor is difficult to dissipate. Therefore, the heat at the junction box of the motor can easily continue to increase due to the inability to dissipate, which poses a certain safety hazard. Utility Model Content

[0003] To address the problem that heat at the motor junction box in existing technologies tends to accumulate due to poor heat dissipation, posing a safety hazard, this application provides a heat dissipation structure for the motor junction box, the specific solution of which is as follows.

[0004] A heat dissipation structure for a motor junction box includes a motor housing with heat dissipation ribs and a terminal block for mounting the junction box. A support rod is provided inside the terminal block, parallel to the heat dissipation ribs, and a vent hole is provided on the support rod, penetrating the support rod and extending along its length.

[0005] By adopting the above technical solutions, the heat dissipation ribs on the motor housing can increase the heat dissipation area and improve the heat dissipation efficiency of the motor housing; the terminal block on the motor housing is used to install the junction box, which facilitates the installation of the junction box; the support rod parallel to the heat dissipation ribs is set in the terminal block, and the ventilation hole through the length direction is opened on the support rod, which allows air to circulate in the ventilation hole and carry away heat, thereby enhancing the heat dissipation effect in the junction box and reducing the problem of overheating of the junction box.

[0006] Optionally, the support rod has heat dissipation holes on its side wall, and the heat dissipation holes are connected to the ventilation holes.

[0007] By adopting the above technical solution, heat dissipation holes are opened on the side wall of the support rod, which are connected to the ventilation holes. This allows air to flow out through the ventilation holes and then out through the heat dissipation holes, further enhancing the heat dissipation effect of the junction box.

[0008] Optionally, the heat dissipation hole is located at the top of the support rod, and the heat dissipation hole is used to allow air to pass through towards the junction box.

[0009] By adopting the above technical solution, heat dissipation holes are opened on the side wall of the support rod, which are connected to the ventilation holes. This allows air to flow out through the ventilation holes and then through the heat dissipation holes, enabling more direct heat dissipation of the inside of the junction box and further improving the heat dissipation effect.

[0010] Optionally, the terminal block has a connecting air passage that communicates with a vent hole and is arranged around the terminal block.

[0011] By adopting the above technical solution, the connecting air passage arranged around the terminal block and connected to the vent further promotes air circulation within the terminal block, enhancing the heat dissipation performance of the junction box and the motor as a whole.

[0012] Optionally, the motor housing is further provided with an external rod, which is arranged parallel to the heat dissipation fins and is coaxial with the support rod.

[0013] By adopting the above technical solution, an external connecting rod with parallel heat dissipation ribs and coaxial with the support rod is set on the motor housing, which can optimize the layout of the heat dissipation structure of the motor junction box, make the airflow of heat dissipation smoother, and further improve the overall heat dissipation efficiency.

[0014] Optionally, the external rod is integrated with the terminal block.

[0015] By adopting the above technical solution, the external rod and the terminal block are integrated, which can enhance the overall structure and stability, make the connection between the external rod and the terminal block more secure, help ensure the connectivity of ventilation and heat dissipation channels, and further improve the heat dissipation effect.

[0016] Optionally, the external rod has a ventilation hole, which is connected to the connecting air passage.

[0017] By adopting the above technical solution, ventilation holes are opened inside the external rod and connected to the connecting air passage. This allows air to pass through the ventilation holes, connecting air passage, vent, and heat dissipation holes in sequence, forming an effective air circulation channel and enhancing the heat dissipation effect of the junction box.

[0018] Optionally, the external rod is located at the end of the motor housing near the fan, while the support rod is located at the end of the motor housing away from the fan.

[0019] By adopting the above technical solution, the airflow generated by the fan can be used to allow air to enter the junction box in sequence through the ventilation holes of the external rod, the connection air passage of the terminal block, the ventilation holes and heat dissipation holes of the support rod, effectively dissipating heat from the junction box. Moreover, the reasonable layout structure makes the airflow path for heat dissipation smoother and more efficient.

[0020] In summary, this application has at least the following beneficial effects: This application solves the problem that the heat at the junction box of the motor in the prior art is easily unable to dissipate and continues to increase, which poses a certain safety hazard. This application improves the heat dissipation effect by setting a support rod that allows air to be introduced into the junction box for heat exchange by directly dissipating heat inside the junction box.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Motor junction box heat dissipation structure, such as Figure 1 and Figure 2 As shown, the device includes a motor housing 1, on which heat dissipation ribs 11 are provided. A terminal block 2 is also provided on the motor housing 1 for mounting a junction box. A support rod 21 is provided inside the terminal block 2, parallel to the heat dissipation ribs 11. A vent 211 is provided on the support rod 21, penetrating the support rod 21 and extending along its length. Specifically, the vent 211 allows air to be introduced into the support rod 21. Since the support rod 21 is located inside the terminal block 2, it can directly exchange heat with the interior of the terminal block 2, thereby cooling the terminal block 2 and improving the heat dissipation effect at the junction box.

[0026] like Figure 1 and Figure 2 As shown, a heat dissipation hole 212 is provided on the side wall of the support rod 21, and the heat dissipation hole 212 is connected to the vent hole 211. The heat dissipation hole 212 is located at the top of the support rod 21 and is used to allow air to pass through the junction box. In practice, air can pass directly through the support rod 21 to directly dissipate heat and cool the inside of the junction box, further improving the heat dissipation effect.

[0027] like Figure 1 and Figure 2As shown, a connecting air passage 22 is provided inside the terminal block 2, which communicates with the vent 211 and is arranged around the terminal block 2. Air also circulates inside the terminal block 2, which can further improve the heat dissipation effect inside the junction box.

[0028] like Figure 1 and Figure 2 As shown, an external rod 3 is also provided on the motor housing 1. The external rod 3 is arranged parallel to the heat dissipation fins 11 and is coaxial with the support rod 21. The external rod 3 is integrally formed with the terminal block 2. A ventilation hole 31 is provided inside the external rod 3, which communicates with the connecting air passage 22. The external rod 3 is located at the end of the motor housing 1 near the fan, while the support rod 21 is located at the end of the motor housing away from the fan. In specific implementation, the external rod 3 can guide the air blown out by the fan into the terminal block 2, thereby further improving the cooling effect.

[0029] Working principle: By directly introducing air into the junction box, the heat dissipation inside the junction box is directly cooled, which solves the problem of poor heat dissipation performance at the junction box and reduces safety hazards.

[0030] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
