Abstract
Photovoltaic inverter room heat abstractor. When the inverter is continuously used to generate large heat, the inverter operates in a high-temperature environment due to poor indoor heat dissipation of the inverter, and the temperature of the inverter is further higher than an alarm value. The service life of the IGBT is seriously influenced, and the limited power operation occurs. The utility model comprises the following components: the air-conditioning cabinet comprises a cabinet body (6), wherein blowers (7) are respectively fixed on the front side and the rear side of the bottom of the cabinet body, an air outlet cover (4) is fixed on the left/right side surface of the cabinet body, a heating wire (5) is fixed in the air outlet cover, the air outlet cover is communicated with one end of an air return pipe (3), and the other end of the air return pipe is communicated to the opposite side surface of the cabinet body and the air outlet cover; and a circulating fan (1) is fixed on the air return pipe. The utility model is used for heat dissipation of the photovoltaic inverter chamber.
Description
Technical Field
The utility model relates to a photovoltaic inverter room heat dissipation device.
Background
The photovoltaic power generation is used as clean energy, no pollutant is discharged, the power generation and the power supply can be carried out on site without consuming fuel and erecting a power transmission line, the limitation of resource distribution regions is avoided, the photovoltaic power generation can be built in regions with complex terrains, the operation is safe and reliable, no noise is generated, and a large amount of manpower and material resources are not consumed for maintenance and repair.
The inverter is placed in the inverter room, and when the temperature is higher in summer, the heat dissipation system of the inverter body can solve the problem of internal heat dissipation, but the heat dissipation efficiency in the inverter room is lower. When the inverter is continuously used to generate large heat, the inverter operates in a high-temperature environment due to poor indoor heat dissipation of the inverter, and the temperature of the inverter is further higher than an alarm value. The service life of the IGBT is seriously influenced, and the limited power operation occurs.
Disclosure of Invention
The utility model aims to provide a photovoltaic inverter room heat dissipation device.
The above purpose is realized by the following technical scheme:
a photovoltaic inverter room heat abstractor, its constitution includes: the air blower is fixed on the front side and the rear side of the bottom of the box body respectively, an air outlet cover is fixed on the left side surface and the right side surface of the box body, a heating wire is fixed in the air outlet cover, the air outlet cover is communicated with one end of a return air pipe, and the other end of the return air pipe is communicated to the opposite side surface of the box body to the air outlet cover;
and a circulating fan is fixed on the air return pipe.
The photovoltaic inverter room heat dissipation device is characterized in that a heat dissipation fan is fixed at the top of the box body.
Has the advantages that:
1. the utility model can adjust the indoor temperature of the photovoltaic inverter, starts the heating wire and the circulating fan to perform heating circulation when the temperature is lower than the set temperature, and starts the blower to blow external low-temperature air into the room to reduce the temperature when the temperature is higher than the set temperature, thereby achieving the purpose of adjusting the indoor temperature of the photovoltaic inverter.
2. The heating wire is arranged, and indoor air circulation is carried out through the air return pipe, so that hot air can be blown into a room under the action of the circulating fan, and the circulation effect of the circulating fan is improved.

FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a circulating fan; 2. a heat radiation fan; 3. a return air duct; 4. an air outlet cover; 5. heating wires; 6. a box body; 7. a blower.
The specific implementation mode is as follows:
example 1:
a photovoltaic inverter room heat abstractor, its constitution includes: the air conditioner comprises a box body 6, wherein blowers 7 are respectively fixed on the front side and the rear side of the bottom of the box body, an air outlet cover 4 is fixed on the left side surface and the right side surface of the box body, a heating wire 5 is fixed in the air outlet cover, the air outlet cover is communicated with one end of an air return pipe 3, and the other end of the air return pipe is communicated to the opposite side surface of the air outlet cover on the box body;
and a circulating fan 1 is fixed on the air return pipe.
Example 2:
according to the photovoltaic inverter room heat dissipation device of embodiment 1, the top of the box body is fixed with the heat dissipation fan 2.
The working principle is as follows: when the air-cooling type inverter is used, the air blower, the circulating fan and the heating wires are not started, heat is dissipated into the inverter chamber through the cooling fan at the moment, the temperature controller is further arranged in the inverter chamber, when the temperature in the inverter chamber is lower than the set temperature of the temperature controller, the heating wires and the circulating fan are started, air in the inverter chamber is circulated, meanwhile, heat generated by the heating wires rapidly circulates into the inverter chamber through the circulating fan, the heating speed is increased, the inverter chamber is uniformly heated, when the temperature in the inverter chamber is higher than the set temperature of the temperature controller, the air blower is started, and external air is blown into the inverter chamber to cool the temperature in the inverter chamber.
