Embodiment 1
[0022] see figure 1 , an outdoor power distribution cabinet with intelligent temperature control function, including a negative temperature coefficient thermistor, a solar power generation system, a refrigerator and a power distribution cabinet body 5, and the negative temperature coefficient thermistor is distributed on the inner wall of the power distribution cabinet body 5 Above, the negative temperature coefficient thermistor, the solar power generation system and the refrigerator are connected in series in sequence. The solar power generation system includes a solar power generation panel 1, which is placed obliquely on the upper part of the shell of the power distribution cabinet body 5, and the refrigerator is located on the solar power generation panel 1. Between the body 5 of the power distribution cabinet, there is also a cold air pipe 3 connected to the refrigerator, and the cold air pipe 3 extends to the top of the inner space of the main body 5 of the power distrib...
Embodiment 2
[0025] In this embodiment, on the basis of Embodiment 1, further, a heat dissipation device is provided at the bottom of the side wall of the power distribution cabinet body 5 . The top of the internal space of the power distribution cabinet body 5 is provided with a cold air pipe 3. When the refrigerator starts to work, the refrigerator generates cold air and flows into the internal space of the power distribution cabinet body 5. At this time, the cold air is located in the internal space of the power distribution cabinet At the top, the hot air sits below the cool air. According to common knowledge, the specific gravity of cold air is greater than that of hot air. Therefore, by providing a cooling device at the bottom of the side wall of the distribution cabinet body 5, the cold air on the top can discharge the hot air from the cooling device to the distribution cabinet, forming effective air convection, and effectively reducing the internal temperature of the distribution c...
Embodiment 3
[0027] In this embodiment, on the basis of Embodiment 2, further, the heat dissipation device is a fixed louver 7 . The use of fixed louvers 7 as a heat dissipation device has the following advantages: (1) It can prevent external rainwater from intruding into the power distribution cabinet body 5, and avoid electrical accidents caused by rainwater intrusion; (2) It can block the strong sunlight outside and avoid sunlight Part of the electric equipment inside the power distribution cabinet causes the temperature of these electric equipment to rise, affecting normal operation; (3) The fixed shutter 7 can not only realize the heat dissipation function, but also have a more beautiful appearance. Other parts of this embodiment are the same as Embodiment 2 and will not be repeated here.
