Description

Technical Field

[0001] The invention belongs to the technical field of heat dissipation of distribution boxes, and in particular relates to an adaptive heat dissipation device for an electrical distribution box. Background Art

[0002] A distribution box is a device used for power distribution and control of electrical equipment in a power system. It is usually used for power distribution in residences, factories, shopping malls and other places. The main function of a distribution box is to centrally control and protect electrical equipment, distribute current to various electrical equipment, and ensure the stable operation of the power grid. It has multiple protection functions such as overload, short circuit, and leakage, which can prevent damage to electrical equipment and personal injury. The operation of the distribution box is relatively simple. The user only needs to turn on or off the switch to control the power supply. It can be configured with different types of switches as needed to meet the needs of different electrical equipment. The distribution box can be integrated in a box to save space. The distribution box is usually designed as a detachable modular structure for easy installation and maintenance.

[0003] Traditional distribution boxes generally use fans for heat dissipation, but after the distribution cabinet is placed outside for a long time, a large amount of dust will accumulate on the surface of the fan used for heat dissipation, which will affect the heat dissipation effect of the distribution cabinet. The existing processing method requires staff to regularly go to the site for maintenance, which is cumbersome and laborious.

[0004] To this end, those skilled in the art have proposed an adaptive heat dissipation device for an electrical distribution box to solve the problems raised by the background technology.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention can form air circulation by providing a first slot with a first heat dissipation mesh plate and a second installation slot with a first heat dissipation fan. The first heat dissipation fan can transport internal heat to the outside to achieve the heat dissipation effect. At the same time, the device installs an external frame plate with a second heat dissipation mesh plate at the position of the first heat dissipation fan.

[0021] (2) The present invention sets a temperature sensor with a wireless signal transmitting module, and sets a wireless signal receiving module on the switch controlling the first cooling fan and the second cooling fan. When the driving motor drives the temperature sensor to move back and forth continuously, the temperature sensor can comprehensively detect the temperature at different positions in the distribution box.

The photovoltaic power generation component is used to provide power supply for various electrical components in the distribution box. The photovoltaic power generation component used is a conventional existing equipment, so it is not described in detail here. In addition, a heat conduction groove with cooling fins is set at the back of the distribution box.
