The purpose of this utility model is to provide a kind of waterproof and good heat dissipation effect, group serial type photovoltaic DC-to-AC converter easy for installation.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of group of serial type photovoltaic DC-to-AC converter comprises:
Be provided with the box body of cover plate and splicing ear;
By heat radiation gear piece, substrate, the installation link plate forms and be installed in radiator on the box body;
Be located at the middle inductance box of heat radiation gear piece,
The front of described cover plate is provided with controller buttons, and the back side of cover plate is being provided with controller with the corresponding position of controller buttons;
Described heat radiation gear piece is connected with substrate;
Between described cover plate and the box body, be connected by screw between box body and the substrate,
It is characterized in that: be provided with marine glue between the back side of described cover plate and the controller, the front of cover plate is provided with waterproof membrane at controller buttons.
Use the heat conduction sealant sealing in the described inductance box.
Between described substrate and the box body, between described cover plate and the box body respectively with the sealing of polyurethane foam glue.
Described substrate is the integral type structure with link plate is installed.
The centre of described installation link plate is provided with mounting knob.
The glue of setting up defences between cover plate and the controller, the front of the cover plate moisture film of setting up defences can play good waterproof action, connecting portion between substrate and the box body, between cover plate and the box body can further be strengthened waterproof effect, thereby prevent that effectively rainwater from entering box body inside with the sealing of polyurethane foam glue.Heat conduction fluid sealant in the inductance box can make the conduction surface of heat increase, thus the radiating efficiency of raising group serial type photovoltaic DC-to-AC converter.The zone line of link plate is installed is established mounting knob, make equipment easier for installation.The utlity model has waterproof, good heat dissipation effect, install, the characteristics such as easy to use, stabilized structure.
