Abstract
The utility model provides a frequency converter, which comprises a frequency converter body, a radiator and a fan, wherein the radiator is arranged on the back part of the frequency converter body; the fan is arranged on the upper part of the frequency converter body; the air outlet of the fan faces upwards; a control circuit, an inverter, a rectifier and a chopper are arranged in the body; the inverter is connected with a wire outlet power supply circuit breaker at a loading end; the front end of the rectifier is connected with a wire inlet power supply circuit breaker; and a fan cover is arranged on the top of the fan. According to the structure of the frequency converter provided by the utility model, the fan is arranged on the upper part of the frequency converter and the air outlet of the fan faces upwards, so that hot air produced by the frequency converter is pumped upwards during radiating of the fan, external dust is prevented from entering an air channel, and the clearing work load of the air channel by using the radiator is reduced.
Description
Technical field
The utility model relates to a kind of frequency converter.
Background technology
Usually to use heat abstractors such as blower fan in the high-power electrical equipments such as existing frequency converter, inverter, when mounted generally with blower fan be installed in these equipment below, blower fan dispels the heat through the air channel blowing to radiator.Yet this radiating mode blows into extraneous dust the air channel of radiator easily, thereby causes dust to stop up the air channel of radiator, is difficult to cleaning.
The utility model content
The purpose of the utility model is to provide a kind of dust that can prevent to get into the air channel of radiator, the frequency converter that is easy to clear up.
For achieving the above object, the utility model provides following technical scheme:
A kind of frequency converter comprises transducer body, radiator and blower fan; Said radiator is installed in the rear portion of said transducer body; Said blower fan is installed in the top of said transducer body, and the air outlet of said blower fan up; Be provided with control circuit, inverter, rectifier, chopper in the said body; Said inverter connects load end and is connected to the outlet power circuit breaker; The front end of said rectifier is connected to the incoming power circuit breaker; Said blower fan top is equipped with fan shroud.
In the structure of the frequency converter of the utility model; Blower fan be installed in frequency converter top and blower fan air outlet up, like this, blower fan can up be extracted the hot gas that frequency converter produces out when heat radiation; Extraneous dust is difficult for getting into the air channel, thereby has alleviated the cleaning work to the air channel of radiator.
Description of drawings
Figure l is the front view of the frequency converter of the utility model.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model:
With reference to figure l, a kind of frequency converter comprises transducer body 1, radiator 2 and blower fan 3; Said radiator 2 is installed in the rear portion of said transducer body 1; Said blower fan 3 is installed in the top of said transducer body 1, and the air outlet of said blower fan 3 up; Be provided with control circuit 4, inverter 5, rectifier 6, chopper 7 in the said body 1; Said inverter 5 connects load end and is connected to outlet power circuit breaker 8; The front end of said rectifier 6 is connected to incoming power circuit breaker 9; Said blower fan top is equipped with fan shroud 10.
In the structure of the frequency converter of the utility model; Blower fan be installed in frequency converter top and blower fan air outlet up, like this, blower fan can up be extracted the hot gas that frequency converter produces out when heat radiation; Extraneous dust is difficult for getting into the air channel, thereby has alleviated the cleaning work to the air channel of radiator.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection range that claims of the utility model confirm.
