Intelligent photovoltaic grid-connected controller

Abstract

An intelligent photovoltaic grid-connected controller disclosed by the present invention comprises a shell, a cooling pool and a mounting rack, the shell is an outer protective shell of the photovoltaic grid-connected controller, the cooling pool is fixedly installed at the lower end of the inner side of the shell, the cooling pool is of a closed structure, and the upper part of the cooling pool is provided with a recessed receding groove used for placing the mounting rack. Meanwhile, the mounting frame is also mounted in the shell, when cooling is needed, the refrigeration piece sucks out heat in the cooling pond in a heat exchange mode, the face, making contact with the cooling pond, of the refrigeration piece can be rapidly cooled, cooling liquid in the pond is cooled, and in the state, the cooling pond can timely guide low temperature in the cooling pond to the mounting frame through a heat conduction rubber pad, so that the cooling effect is improved. Compared with the prior art, due to the fact that the installation frame is rapidly cooled, the operation elements arranged on the installation frame can be timely cooled, compared with air cooling heat dissipation, the efficient heat dissipation effect can be achieved, and compared with water cooling heat dissipation formed by cooling pipes, structural components are simpler, and power consumption is lower.

Description

technical field [0001] The invention relates to the technical field of controllers, in particular to a smart photovoltaic grid-connected controller. Background technique [0002] The photovoltaic controller is an automatic control device used in the solar power generation system to control the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load. It is a microcomputer data acquisition and monitoring control system. Therefore, photovoltaic grid-connected control Whether the device can operate stably and reliably is particularly important, and the impact on the reliable and stable operation of the equipment mainly includes two aspects: one is efficient thermal management of components, avoiding long-term components working in high temperature range, reducing life and reliability; second, equipment The overall protective performance prevents external water and dust particles from entering the box and affecting the work ...
