Summary of the invention
The present invention is directed to Intelligent wiring box heat radiation in prior art bad, cause the technical problem that intelligent chip working temperature is too high, provide a kind of Intelligent wiring box of ventilation and heat, rapid heat dissipation, thus effectively by the working temperature of low price intelligent chip, the useful life of Intelligent wiring box can be extended.
For this reason, the present invention adopts following technical scheme:
An Intelligent wiring box for ventilation and heat, the PCB(9 comprising box body (1), lid (2) and be arranged in box body (1)); It is characterized in that: described PCB(9) on be provided with intelligent chip, PCB(9) be encapsulated in box body (1) by the casting glue (3) that heat conductivility is good, the height of casting glue (3) is less than the height of box body (1) thus in box body, above casting glue, forms an air layer (4), and lid (2) is provided with the radiator window (5) being communicated with described air layer (4).By the casting glue that heat conductivility is good, the amount of heat that intelligent chip is sent is passed in the air layer above line box inside, casting glue, air themperature in air layer rises rapidly, and by the radiator window on lid, heat is delivered to outside line box, effectively can reduce the temperature of intelligent chip in terminal box, meanwhile, because PCB is wrapped in casting glue, reliability is high.
Further, in box body (1), along the sidewall of box body, be provided with some excessive glue grooves (6), the height of the glue groove (6) that overflows is less than the height of box body (1), in excessive glue groove, on the sidewall of box body, be provided with the first louvre (7).Efficient, good heat dissipation channel is formed by radiator window with between the first louvre and extraneous air at air layer, the glue groove that overflows, rapid heat dissipation, perfect heat-dissipating,
Further, box body is also provided with the described air layer (4) second louvre (8) of connection.Further enhancing radiating effect.
Further, described radiator window (5) has some inclined elongate (5a) arranged abreast.Take into account intensity and the radiating effect of terminal box.
Further, described box body (1) is installed on installation panel, and installation panel forms the bottom of box body (1).Box body (1) itself does not have bottom, during use, be bonded on corresponding installation panel (backboard as solar cell) by fluid sealant etc., corresponding installation panel forms the bottom of box body, by casting glue embedding in box body, like this, the heat produced in intelligent chip running can be directly delivered to installation panel (backboard as solar cell) by the casting glue that heat dispersion is good, and need not again bottom alternating floor box body, advantageously in heat radiation.
Further, described box body (1) and lid (2) removably connect.Be convenient to check, change and maintenance.
To sum up, the present invention passes through the good casting glue of heat conductivility, the amount of heat that intelligent chip is sent is passed in the air layer above line box inside, casting glue, air themperature in air layer rises rapidly, by the first louvre in the radiator window on lid, the second louvre and excessive glue groove, good air flow circuits is formed between the air layer and extraneous air of terminal box, heat is delivered to efficiently outside line box, effectively can reduce the temperature of intelligent chip in terminal box, simultaneously, because PCB is wrapped in casting glue, reliability is high.
