[0012] The advantages of this machine tool power distribution cabinet are as follows: This invention absorbs heat from electrical components through a heat-conducting plate and dissipates it through heat dissipation fins.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1, as Figure 1-2 As shown, this utility model provides a technical solution: a machine tool power distribution cabinet, including a cabinet 1, an exhaust fan mounting frame 2, and a cooling cavity 6. The exhaust fan mounting frame 2 is installed on the top of the cabinet 1, and an exhaust fan is installed inside the exhaust fan mounting frame 2. A cooling cavity 6 is opened on the rear inner wall of the cabinet 1 and communicates with the output end of the exhaust fan. An air inlet pipe 4 is installed at the bottom end of the cooling cavity 6. A ventilation fan mounting frame 3 is installed on one side wall of the cabinet 1. A door panel 5 is hinged to the outer wall of the cabinet 1, and a ventilation fan is installed inside the ventilation fan mounting frame 3. A heat dissipation component for cooling the electrical components on the inner wall of the cabinet 1 is installed inside the cooling cavity 6. The heat dissipation component includes a heat-conducting plate 8 and heat dissipation fins 9. A heat-conducting plate 8 connected to the rear wall of the electrical components is installed on the inner wall of the cooling cavity 6, and the heat-conducting plate 8 is located away from the rear wall of the electrical components. Multiple heat dissipation fins 9 are provided on the inner side of the electrical components. The heat dissipation fins 9 are S-shaped, and heat dissipation holes 901 are equally spaced inside the heat dissipation fins 9. The heat dissipation holes 901 are funnel-shaped. By placing an exhaust fan in the exhaust fan mounting frame 2, the heat is absorbed by the heat conduction plate 8 and then dissipated through the heat dissipation fins 9. When the air is turned on, the air enters the cooling cavity 6 from the air inlet 4 through the air outlet of the exhaust fan mounting frame 2, and the heat is carried away from the heat dissipation fins 9 in the cooling cavity 6. At the same time, the module mounting frame 7 is provided on the inner wall of the cabinet 1, which can simultaneously carry away the hot air from the cabinet 1 and exhaust it to the external environment. With the ventilation fan in the ventilation fan mounting frame 3 turned on, the heat inside the cabinet 1 is exhausted, improving the heat dissipation effect inside the cabinet 1, meeting daily needs, reducing the failure rate, and increasing the service life.
[0018] Example 2, as Figure 1-5As shown, this utility model provides a technical solution: a machine tool power distribution cabinet, including a module mounting frame 7 installed inside the cabinet 1. The inner wall of the module mounting frame 7 is equipped with a temperature and humidity sensor 701, an arc light sensor 702, a microcontroller 703, and a communication module 704. The temperature and humidity sensor 701 is model YS-12, and the arc light sensor 702 is model DG-HB. The output terminals of the temperature and humidity sensor 701 and the arc light sensor 702 are electrically connected to the input terminal of the microcontroller 703 via wires. The microcontroller 703 is a WiFi module used to send early warning information to the mobile phones of maintenance personnel. The temperature and humidity sensor 701 detects the temperature and humidity at the cabinet 1 and feeds the detection information back to the microcontroller 703. The communication module 704 detects an arc within the cabinet 1, and the microcontroller 703 can send early warning information to the mobile phones of remote maintenance personnel via the communication module 704, thus achieving predictive maintenance and providing early warnings for potential faults.
[0019] Working principle: First, connect the external power supply. Operators can cool the heat inside the cabinet 1 by activating the exhaust fan mounting frame 2 and the ventilation fan mounting frame 3. The heat is first absorbed by the electrical components through the heat conduction plate 8, and then dissipated through the heat dissipation fins 9. The air enters the cooling cavity 6 through the air inlet 4 through the air inlet of the exhaust fan mounting frame 2, and the heat is carried away by the heat dissipation fins 9 in the cooling cavity 6. At the same time, the ventilation fan mounting frame 3 is activated to expel the heat inside the cabinet 1, improving the heat dissipation effect inside the cabinet 1. The cabinet 1 is equipped with a module mounting frame 7. Operators can set the temperature, humidity and arc light warning values of the microcontroller 703. When the parameters are abnormal, the warning information can be sent to the mobile phone of the remote maintenance personnel through the communication module 704. The operator can monitor the key operating status of the cabinet 1, such as temperature, humidity and arc light, in real time.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
