The power devices are arranged in the horizontal shape, and are installed above the radiator in parallel, the air inlet of the radiator is at the wide edge, when the air flow enters into an air channel of the radiator, the radiating fins under each power device is provided with the air flow with the same temperature, via the radiating fins and through the air outlet, heat is taken away, thereby effectively improving heat radiation efficiency of the radiator, under the condition of the same wind speed, utilization rate of the radiator reaches the highest, and production manufacture cost of the photovoltaic inverter is not increased.

Description

A kind of radiator structure of photovoltaic inverter power unit
Technical field
The utility model relates to a kind of radiator structure, relates in particular to a kind of radiator structure of photovoltaic inverter power unit.
Background technology
Photovoltaic inverter power unit of the prior art is after considering the factors such as convenient design copper bar and electrical structure performance, the heat dissipation design that adopts generally as shown in Figure 1, air inlet is positioned at a side of radiator minor face, so the air channel in the radiator is not only long, and after the accumulation through the heat radiation of each device, the device heat radiation that is positioned at the air outlet side difficult that will become.Present solution is to strengthen the area of dissipation of radiator (volume that increases radiator has namely increased cost) and increase wind speed (need larger blower fan, thereby increased cost).
The utility model content
The purpose of this utility model is to provide a kind of radiator structure of photovoltaic inverter power unit, under the prerequisite that guarantees the electrical structure performance, improves the radiating efficiency of radiator, reduces the volume of power cell, reduces the cost of whole high voltage converter.
The utility model adopts following technical scheme to realize:
A kind of radiator structure of photovoltaic inverter power unit, comprise radiator and the power device that is installed in the radiator top, arrange the fin space of radiator bottom, the two ends of fin axis direction are respectively air inlet and air outlet, it is characterized in that described power device is in one line in the top of radiator, described radiator has broadside and minor face, air inlet lays respectively on two relative broadsides of radiator with air outlet, and the flow direction that air-flow enters behind the fin is consistent with minor face.
Further, the interval between the described power device is equal to or greater than 30mm.
The useful technique effect that the utility model possesses is:
Power device is in one line, the radiator top that is mounted on parallel to each other, radiator air intake opening is its broadside, the fin of each power device below will have the air-flow of uniform temp when air-flow enters the air channel of radiator, by air outlet heat is taken away through fin, the radiating efficiency of energy Effective Raise radiator is in the situation of identical wind speed again, can make the utilance of radiator reach the highest, and not increase the manufacturing cost of photovoltaic DC-to-AC converter.
Description of drawings
Fig. 1 is the radiator structure schematic diagram of photovoltaic inverter power unit in the prior art.
Fig. 2 is the radiator structure schematic diagram of the utility model photovoltaic inverter power unit.
Embodiment
By following description to embodiment; to more help public understanding the utility model; but can't the specific embodiment that the applicant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection range that the technical solution of the utility model limits.
As shown in Figure 1, photovoltaic inverter power unit of the prior art is after considering the factors such as convenient design copper bar and electrical structure performance, the heat dissipation design that adopts generally is minor face one side that air inlet is positioned at radiator, so the air channel that enters in the radiator is not only long, and after the accumulation through each device heat radiation, the device heat radiation that is positioned at the air outlet side difficult that will become, present solution is to strengthen the area of dissipation of radiator and increase wind speed, obviously this need to increase radiator and volume and need larger blower fan, has increased cost.
The radiator structure of the utility model photovoltaic inverter power unit as shown in Figure 2, comprise radiator 1 and the power device 2 that is installed in the radiator top, radiator 1 is the scale radiator, arrange following fin space, the two ends of fin axis direction are respectively air inlet and air outlet, power device 2 is in one line in the top of radiator 1, radiator 1 has broadside 3 and minor face 4, a plurality of power devices 2 in one line are parallel with broadside 3, air inlet lays respectively on two relative broadsides 3 of radiator 1 with air outlet, the flow direction that air-flow enters behind the fin is consistent with minor face 4, and the interval between the power device 2 is equal to or greater than 30mm.Power device 2 is in one line, radiator 1 top that is arranged on parallel to each other, the air intake opening of radiator 1 is its broadside, when air-flow has just entered the air channel of radiator 1, the fin of each power device below will have the air-flow of uniform temp, and air-flow is through the fin of device below, by outlet heat is taken away again, the radiating efficiency of energy Effective Raise radiator in the situation of identical wind speed, can make the utilance of radiator reach the highest.The utility model has re-started radiator structure design and layout for photovoltaic inverter power unit, compare with the power cell of the prior art of same size, thereby the radiating efficiency that improves radiator can reduce the volume of power cell, has reduced the cost of whole high voltage converter.A photovoltaic DC-to-AC converter often uses a plurality of power cells, has reduced the volume of single power cell and the cost of single power cell, just can greatly reduce volume and the cost of whole photovoltaic DC-to-AC converter accordingly.
Certainly; the utility model can also have other various embodiments; in the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
