Description
Technical field
This utility model relates to a kind of radiator structure, particularly a kind of group string inverter radiator structure.
Background technology
At present; portion's packet chain inverter uses the mode of IGBT and Mosfet pipe wind-cooling heat dissipating; inductance uses the mode of natural heat dissipation; inductance natural heat dissipation need to use custom-designed encapsulation aluminum hull, and the heat radiation gear piece of complexity need to be designed in aluminum hull surface, is beneficial to heat radiation; the encapsulation aluminum hull often cost of this band heat radiation gear piece is high; versatility is not strong, and inductance natural heat dissipation temperature would generally be higher, and the service life of inductance is had an impact by life-time service.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of good heat dissipation effect and group string inverter radiator structure with low cost.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of group string inverter radiator structure, it is characterized in that: comprise group string inverter casing, heat sink, inductance, inductance enclosure, fan and sealing cover, heat sink is fixed in the middle of group string inverter casing back and heat sink and is provided with some heat radiation gear pieces, heat radiation gear piece is horizontally fixed on heat sink and some heat radiation gear pieces are from top to bottom evenly distributed on heat sink side, several inductance are separately fixed on the heat sink of heat radiation gear piece upper and lower sides, outside several sheathed inductance of inductance enclosure, inductance encapsulation and inductance enclosure are fixed on heat sink, gap is left between inductance enclosure and heat radiation gear piece, fan is arranged on group side, string inverter casing side, group has air outlet on string inverter casing opposite side side, sealing cover is fixed on outside heat sink and sealing cover inwall is fitted with heat radiation gear piece.
Further, described group of string inverter casing, heat sink, inductance enclosure and sealing cover all use aluminum material.
Further, described group of string inverter casing is the aluminum hull riveting, welding or cast.
Further, the riveting of described inductance enclosure is fixed on heat sink.
Further, described fan be two and two fans setting up and down at group string inverter body side, two fans distances up and down will heat radiation gear piece and heat radiation gear piece with including the covering of inductance enclosure gap.
This utility model compared with prior art, has the following advantages and effect:
1, inductance enclosure simple in construction, does not has gear piece structure, and difficulty of processing is low, low cost；
2, gear piece is not only dispelled the heat by fan, inductance enclosure can be carried out wind-cooling heat dissipating simultaneously, is effectively improved the radiating efficiency of inductance, improves device serviceability；
3, radiator can install inductance and power device, and device integration degree is high, reduces installation volume；
4, inductance enclosure is arranged on radiator base plate, in the thermal conductance that can be produced by inductance to radiator, improves inductance radiating efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of group of string inverter radiator structure of the present utility model.
Fig. 2 is the schematic diagram of the sealing cover that closes of a kind of group of string inverter radiator structure of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are that this utility model is not limited to following example to explanation of the present utility model.
nullAs shown in the figure，A kind of group string inverter radiator structure of the present utility model，Comprise group string inverter casing 1、Heat sink 2、Inductance、Inductance enclosure 3、Fan 4 and sealing cover 5，Heat sink 2 is fixed in the middle of group string inverter casing 1 back and heat sink 2 and is provided with some heat radiation gear pieces 6，Heat radiation gear piece 6 is horizontally fixed on heat sink 2 and some heat radiation gear pieces 6 are from top to bottom evenly distributed on heat sink 2 side，Several inductance are separately fixed on the heat sink 2 of heat radiation gear piece 6 upper and lower sides，Outside several sheathed inductance of inductance enclosure 3, inductance encapsulation and inductance enclosure 3 are fixed on heat sink 2，Gap is left between inductance enclosure 3 and heat radiation gear piece 6，Fan 4 is arranged on group side, string inverter casing 1 side，Group has air outlet 7 on string inverter casing 1 opposite side side，Sealing cover 5 is fixed on outside heat sink 2 and sealing cover 5 inwall is fitted with heat radiation gear piece 6.
Group string inverter casing 1, heat sink 2, inductance enclosure 3 and sealing cover 5 all use aluminum material, thus reach preferable radiating effect.Group string inverter casing 1 is the aluminum hull riveting, welding or cast.Inductance enclosure 3 riveting is fixed on heat sink 2, so fixes more firm and heat-transfer effect is good.Fan 4 be two and two fans 4 setting up and down in group string inverter casing 1 side, two fans 4 about distances will be including heat radiation gear piece 6 and heat radiation gear piece 6 and the covering of inductance enclosure 3 gap.
Pass through technique scheme, the when of a kind of group string inverter radiator structure work of the present utility model, cold wind is blown in group string inverter casing 1 on the right side of group string inverter casing 1 by fan 4, air is divided into upper, middle and lower three part, the wind on top carries out wind-cooling heat dissipating to the inductance enclosure 3 above heat radiation gear piece 6, inductance enclosure 3 below heat radiation gear piece 6 is dispelled the heat by bottom wind, heat radiation gear piece 6 is dispelled the heat by middle part wind, the heat of heat radiation gear piece 6 is essentially from organizing string inverter casing 1 back side power device and passing through the heat of the inductance that heat sink 2 transmits, final hot blast air outlet 7 on the left of group string inverter casing 1 blows out.
