Specific embodiment
A kind of skill of the cooling system of inverter this utility model being related to below in conjunction with preferred embodiment and its accompanying drawing
Art scheme is further non-limitingly described in detail.
Refer to shown in Fig. 1, an embodiment of the present utility model provides a kind of cooling system of inverter, its use
Use in concentrating the power cabinet 100 placing inverter.
It includes the tube system that radiates, including substrate 10 and the radiating tube 12 being arranged on described substrate 10.Wherein said
Substrate 10 is arranged on precalculated position by radiating silica gel sheet 14.Select silica gel piece, be because its can blind, complete generate heat
Position and the heat transfer of endothermic section interdigit, also act as insulation, cushioning effect simultaneously, but are not limited to.
Wherein said radiating tube 12 position is divided into two parts: the closing chamber of the power cabinet 100 in described inverter for the part
In 101, another part is passed through ventilation shaft 103 lower shoe that top of chamber closed by inverter power cabinet, is in inverter power
In the ventilation shaft 103 of cabinet 100.The ventilation shaft 103 of described inverter power cabinet 100 is from the power cabinet 100 of described inverter
The front end at top extends to rear end.
During use, described radiating silica gel sheet 14 is conducted heat on heat pipe substrate 10 by way of conduction of heat, then
It is transmitted to the tube wall of radiating tube 12 from described substrate 10, then heat is transmitted to the liquid of as received basis in it from the tube wall of radiating tube
In body, it is pumped into negative pressure state due to inside radiating tube 12, boiling point of liquid is low, easily heat absorption volatilization, by heat in described radiating tube
From its evaporation ends, condensation end is delivered to by insulating segment in 12, concrete principle refers to shown in Fig. 2.
Then, by the aerofoil fan 16 in the ventilation shaft 103 of the power cabinet 100 being arranged on described inverter to described
Constantly blowing is cooled down for the condensation end of copper radiating tube 12, and the liquefaction of steam state working medium discharges heat, and the strong convection of air is by heat
Constantly take away, and steam constantly condenses in condensation end inner surface, because described radiating tube 12 is to be disposed vertically, the liquid of condensation
Automatically evaporation ends are flowed back in the effect that capillary force can be leaned on along capillary-porous material under gravity, complete an interior circulation, and because
The continuous absorption of copper radiating tube evaporator section heat and condensation end heat constantly discharge and circulate and go on.
Heat reaches other end by described radiating tube one end, is quickly circulated, and continuously passes through copper radiating tube
Carry out conduction of heat and again convection current is carried out by described aerofoil fan Final 16 system, active heat removal, due to by conduction of heat and thermal convection current side
Heat can be efficiently dispersed into the in the air outside cabinet by formula, thus having ensured setting in described inverter power cabinet 100
The normal work of power electronic devices.
Further, front filter screen 102 and rear filter screen 104 can be set in described inverter power cabinet 100 side top, use
To stop dust from being attached on aerofoil fan 16 and copper radiating tube 12, reduce stall, the speed that dust brings to aerofoil fan 16
Slow impact and the impact that radiating rate is slow, effect is poor that copper radiating tube 12 is brought.
Wherein radiating tube preferred copper radiating tube, because the thermal conductivity coefficient of copper radiating tube is more than 100 times of common metal, with
Low thermal resistance carries out the transmission of heat, has radiating efficiency height, good heat dissipation effect, and thermal response speed is fast, structure simple, weight
Gently, the advantages of small volume, easy to maintenance, long service life.And inverter power cabinet enclosure portion has higher protection etc.
Level, so both can guarantee that centralized inverter radiating effect, is avoided that dust enters in inverter simultaneously again, reduces dust to inverse
Become the adverse effect that the power electronic equipment of device causes, extend the service life of inverter, in photovoltaic plant life cycle,
Reduce the human and material resources paid and the loss of invisible generated energy, reduce cost.
A kind of inverter cooling system that this utility model is related to, its radiating being combined using radiating tube and cooling fan
Mode cools down to centralized photovoltaic DC-to-AC converter, good heat dissipation effect, efficiency high.
