Problem, there is provided a kind of intelligent wiring box of ventilation and heat, rapid heat dissipation, so as to effectively by the work temperature of low price intelligent chip
Degree, extends the service life of intelligent wiring box.
For this reason, the present invention adopts the following technical scheme that：
A kind of intelligent wiring box of ventilation and heat, including box body (1), box lid (2) and the PCB being arranged in box body (1)
(9)；It is characterized in that：Intelligent chip is provided with the PCB (9), PCB (9) is sealed by the good casting glue of heat conductivility (3)
In box body (1), the height of casting glue (3) is less than the height of box body (1) so that in box body, the top formation one of casting glue
Air layer (4), is equipped with the radiator window (5) for connecting the air layer (4) on box lid (2), in box body (1), along the side of box body
Wall is provided with some excessive glue grooves (6), and the height of excessive glue groove (6) is less than the height of box body (1), in excessive glue groove, the side wall of box body
On be provided with the first heat emission hole (7), box body (1) itself does not have bottom.By the good casting glue of heat conductivility, make intelligent core
The amount of heat that piece is sent is transferred to inside wire box, in the air layer above casting glue, and the air themperature in air layer is rapid
Rise, and transferred heat to by the radiator window on box lid outside wire box, the temperature of intelligent chip in terminal box can be effectively reduced
Degree, simultaneously as PCB is wrapped in casting glue, reliability is high；Pass through radiator window and the first heat emission hole in air layer, excessive glue groove
Efficient, good heat dissipation channel, rapid heat dissipation, perfect heat-dissipating are formed between extraneous air.
Further, connection (4) second heat emission hole (8) of air layer is additionally provided with box body.Further enhance scattered
Thermal effect.
Further, the radiator window (5) has some inclined elongates (5a) being set in parallel.Take into account the strong of terminal box
Degree and heat dissipation effect.
Further, the box body (1) is installed in installation panel, and installation panel forms the bottom of box body (1).Box body
(1) itself do not have bottom, in use, being bonded in corresponding installation panel (backboard of such as solar cell) by fluid sealant etc.
On, corresponding installation panel forms the bottom of box body, and box body is interior by casting glue embedding, in this way, in intelligent chip operational process
The heat of generation can be directly delivered to installation panel (backboard of such as solar cell) by the good casting glue of heat dissipation performance,
And without alternating floor box body bottom again, it is more conducive to heat dissipation.
Further, the box body (1) is detachably connected with box lid (2).Easy to check, replace and repair.
To sum up, the present invention is transferred to the amount of heat that intelligent chip is sent by the good casting glue of heat conductivility
In air layer inside wire box, above casting glue, the air themperature in air layer rises rapidly, by the radiator window on box lid,
The first heat emission hole in second heat emission hole and excessive glue groove, good sky is formed between the air layer and extraneous air of terminal box
Flow of air circuit, heat is efficiently delivered to outside wire box, can be effectively reduced the temperature of intelligent chip in terminal box, meanwhile,
Since PCB is wrapped in casting glue, reliability is high.
