Abstract

The utility model provides an efficient heat dissipation device of a photovoltaic inverter, which comprises a centrifugal fan, an air duct and heat sinks, wherein the air duct is sequentially provided with an air diffusing port, a heat dissipation area and an air outlet, and the air diffusing port is provided with an air inlet end which is communicated with the centrifugal fan, and an air outlet end which is communicated with the heat dissipation area; the heat dissipation area is oppositely matched with a power device of the photovoltaic inverter, and the heat sinks are fixedly arranged in the heat dissipation area and are matched with the power device in a contact way; the heat dissipation area and the power device are oppositely arranged, and the heat sinks are directly contacted with the power device capable of generating high energy; the energy of the power device is transferred to the heat sinks, and air from the centrifugal fan flows through the air diffusing port and then reaches the heat dissipation area, and blows towards the heat sinks of the heat dissipation area and leaves the air duct through the air outlet. The particularly increased volume of the heat dissipation area is favorable for installing the large-area heat sinks, thereby increasing the contact area of the air in the air duct and the heat sinks; and the heat dissipation device has the advantage of high heat dissipation efficiency, and the service life of the power device is improved.

Description

The heat abstractor of photovoltaic DC-to-AC converter
Technical field
The utility model relates to the heat radiation of all high-power photovoltaic inversion units and filter reactor, carries out the heat abstractor of quick heat radiating especially at the photovoltaic DC-to-AC converter of large-scale power.
Background technology
Existing photovoltaic DC-to-AC converter heat dissipation technology is roughly integral heat sink, dispel the heat at inverter internal transformer, reactor, inversion unit integral body exactly, this heat dissipation technology is difficult to be suitable for to high-power type, it is too low radiating efficiency to occur, heat radiation does not reach the defective of the instructions for use of main devices, so high-power photovoltaic DC-to-AC converter heat dissipation problem is a difficult point always.
Summary of the invention
In order to overcome above-mentioned existing photovoltaic DC-to-AC converter heat dissipation technology defective, the utility model provides the efficient radiating apparatus of photovoltaic DC-to-AC converter.
The utility model provides the heat abstractor of photovoltaic DC-to-AC converter, comprise centrifugal blower, air channel and fin, described air channel is provided with successively expands air port, radiating area and air outlet, expand the air port and have air intake that is connected with described centrifugal blower and the outlet air end that is connected with radiating area, the power device of radiating area and photovoltaic DC-to-AC converter is over against cooperating, described fin be fixedly mounted in the radiating area and with the power device contact matching.
The heat abstractor of the utility model photovoltaic DC-to-AC converter, radiating area and power device are over against installation, fin directly contacts with the power device that produces big heat, the heat transferred of power device is to fin, the wind of centrifugal blower arrives radiating area after expanding the air port, blow to the fin of radiating area and leave the air channel by air outlet, the special radiating area volume that increases helps installing large-area fin, thereby the wind in the raising air channel and the contact area of fin, have the radiating efficiency height, improve the advantage of the working life of power device.
Below in conjunction with drawings and Examples the utility model is described in further detail.
