Description

A kind of heat abstractor of inverter power supply cabinet
Technical field
The utility model relates to a kind of power supply cabinet, especially a kind of heat abstractor of inverter power supply cabinet.
Background technology
Improving energy efficiency and Renewable Energy Development has become two wheels of global energy sustainable development, changes the continuous utilization of regenerative resource the most at last over to.Photovoltaic/wind power grid-connected generating technology is the important component part of renewable energy technologies development, and photovoltaic/wind-force parallel network reverse device is the critical piece in the grid-connected system, and it bears the important task of energy conversion.Although China's regenerative resource has huge resource potential, the part technology has realized commercialization, and photovoltaic/wind power grid-connected generating technology has also obtained tremendous development, but still come with some shortcomings.
At present; Also there is the problem of aspects such as protection, thermal design in photovoltaic/wind power grid-connected generating device for the open air use; Show as following some: the first because the circuit part of inverter power supply case mostly adopts sealing fully, and the atmosphere draught-free in the seal chamber; Cause the temperature of local pyrexia components and parts too high, thereby influence the useful life of components and parts; The second, if the inverter power supply casing adopts the semitight state, there is the problem of water proofing property difference again, can't reach the classification of waterproof requirement of outdoor products IP65.
The utility model content
The purpose of the utility model is to provide a kind of can avoid occurring the too high phenomenon of casing inner region temperature, effectively reduce the heat abstractor of the inverter power supply cabinet of seal case internal temperature.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme: a kind of heat abstractor of inverter power supply cabinet comprises the casing of being made up of preceding casing and afterframe; The back side of the base plate of casing before afterframe is welded on; Front shroud is installed, mounting rear cover plate on the afterframe, the middle part welding diaphragm of preceding casing on the preceding casing; Dividing plate is divided into upper and lower cavity with the cavity that preceding casing and front shroud surrounded, and on the plate face of dividing plate blower fan is installed.
Can know by technique scheme; The casing of the utility model is made up of preceding casing and afterframe, and forward and backward cover plate is installed to form seal chamber on preceding casing and afterframe respectively, and blower fan is installed in seal chamber; Make the air in the seal chamber form interior circulation; With temperature than the spread heat in higher place to the lower place of other temperature, so just avoid occurring the too high phenomenon of casing inner region temperature, prolonged the useful life of the interior components and parts of casing.
Description of drawings
Fig. 1,2 is the contour structures sketch map of the embodiment of the utility model;
The structural representation of casing, dividing plate before Fig. 3,4 is respectively among the embodiment of the utility model;
Fig. 5 is the structural representation after the embodiment of the utility model removes front shroud;
Fig. 6 is the A-A cutaway view of Fig. 5.
Embodiment
Like Fig. 1,2, shown in 5; First embodiment of the utility model comprises the casing of being made up of preceding casing 10 and afterframe 20, and front shroud 30 is installed at the back side of the base plate 11 of casing 10 before afterframe 20 is welded on the preceding casing 10; Mounting rear cover plate 40 on the afterframe 20; The middle part welding diaphragm 14 of preceding casing 10, dividing plate 14 is divided into upper and lower cavity with preceding casing 10 and the cavity that front shroud 30 is surrounded, and blower fan 50 is installed on the plate face of dividing plate 14; Offer louvre 41 on the described back shroud 40, be convenient to heat radiation.It is thus clear that the front and back side of the casing of this power supply box is installed front shroud 30 and back shroud 40 respectively, make box house form airtight space, to reach the requirement of waterproof.
Further; Like Fig. 3,4,5, shown in 6; Casing 10 is by base plate 11 and be arranged on riser 12 around the base plate 11 and surround and form before described, and crossbeam 13 is erected between the riser of the left and right sides, and the two ends up and down of dividing plate 14 all are provided with flanging 14a; The upper end of dividing plate 14 is welded on the crossbeam 13 through flanging 14a; On the base plate 11 of casing 10, offer the installing hole 14b that is used to install blower fan 50 on the described dividing plate 14 before the lower end of dividing plate 14 is welded on through flanging 14a, between the and arranged on left and right sides riser of dividing plate 14 and preceding casing 10 spacing is arranged all.Offer a plurality of wire hole 11a that supply to go between and draw on the base plate 11 of casing 10 before described, on each wire hole 11a waterproof terminal 15 is installed all, the number of described wire hole 11a is 6.The blower fan of installing on the dividing plate 14 50 is when work; Because the two ends of dividing plate 14 do not contact with preceding casing 10; Space between dividing plate and the preceding casing 10 has formed the air channel of interior circulation, and the airflow direction in air channel will be distributed to the lower place of other temperature from the high place of temperature through the heat in the blower fan cavity like this shown in the arrow among Fig. 5; Reduce the bulk temperature in the cavity, thereby prolonged the useful life of components and parts.
In sum; The casing of the utility model is made up of with afterframe 20 preceding casing 10, and forward and backward cover plate 30,40 is installed to form seal chamber on preceding casing 10 and afterframe 20 respectively, and blower fan 50 is installed in seal chamber; Make the air in the seal chamber form interior circulation; With temperature than the spread heat in higher place to the lower place of other temperature, so just avoid occurring the too high phenomenon of casing inner region temperature, prolonged the useful life of the interior components and parts of casing.
