Abstract
The utility model relates to a stander type frequency-conversion dynamo which comprises a wind-guiding cover (2), an inverter (3) provided with an inverter lug (7), a fan (4) and a stander (8). The stander type frequency-conversion dynamo is characterized in that the inverter (3) is arranged at the downstream of the fan (4). As the technical proposal is adopted, the utility model has the advantages that the working efficiency of the inverter is improved, the whole length of a unit is shorted, and the space utilization ratio inside the unit is improved.
Description
Technical field
The utility model relates to a kind of generator, particularly a kind of frequency conversion generator.
Background technique
As everyone knows, one group of heater element---inverter is arranged in existing frequency conversion generator, original inverter is the place ahead that is installed on the unit wind scooper, and installation must cause the unit entire length longer like this, causes its unit inner utilization rate not high.And inverter can produce heat when work; when the inverter temperature is too high; inverter will start the high temperature protection function and cause normally output power of unit; need wait the inverter temperature drop to once more can the startup degree after unit could normal output power; in a word; if the inverter cooling effect is bad, can cause unit proper functioning continuously.The method that the cooling of inverter is adopted usually is that inverter is installed on unit wind scooper the place ahead at present, thereby the cold wind when utilizing the fan air draught is crossed from the inverter surface flow and is entered fan again and play cooling action to inverter, do although it is so and can play the effect that cools, but its cooling effect is not good inverter.
The model utility content
The purpose of this utility model just provides a kind of rack frequency conversion generator that can shorten the unit entire length.
The purpose of this utility model is to realize by such technological scheme: a kind of rack frequency conversion generator, include inverter, fan and the frame of wind scooper, band inverter journal stirrup, inverter is arranged on the downstream of fan, described fan downstream is meant with the fan blade to be the boundary, air intake surface is above to be the upstream, and outlet air surface is following to be the downstream.
In order further to shorten the length of whole unit, improve unit inner utilization rate, inverter be arranged on the wind scooper be the center around, promptly inverter can tilt to install at any angle.
For cool air is more directly lowered the temperature to inverter, described wind scooper is provided with tap hole, and inverter is corresponding with tap hole; The size of tap hole and quantity can design voluntarily according to the needs of Environmental Conditions, to reach the purpose of fast inverter being lowered the temperature.
Described tap hole can be arranged on wind scooper directly over, described inverter be arranged on tap hole corresponding directly over.Certainly, described tap hole also can be arranged on the sidewall of wind scooper, described inverter be arranged on tap hole over against a side.
Described inverter can be connected with frame by the inverter journal stirrup.
The utility model is work like this: by the control panel ato unit, after engine operation, fan constantly rotates under the drive of motor, the fan that rotates sucks cool air, cool air draws dish to enter into fan through air-inlet grille, wind scooper, startup successively, and fan blows to motor with the cool air that sucks, and motor is lowered the temperature, after the heat of cool air and motor carries out heat exchange, discharge by baffler assembly, air discharge grille.Be inhaled in the process of fan at cool air, in the time of cool air process wind scooper, wherein a part of cool air directly blows to inverter through the tap hole on the wind scooper, and the heat that produces when making the work of cool air and inverter carries out heat exchange, so just inverter is lowered the temperature.
Owing to adopted technique scheme, the utlity model has following advantage:
1. the cold wind during the fan air draught directly blows to inverter through tap hole, and inverter is cooled off, and has improved the working efficiency of inverter.
2. change the position of inverter, shortened the unit entire length, improved the unit space availability ratio of inner.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
In order to shorten the length of whole unit, improve unit inner utilization rate, inverter 3 be arranged on wind scooper 2 be the center around.
For cool air is more directly lowered the temperature to inverter, be provided with two tap holes 6 directly over the described wind scooper 2, inverter 2 is corresponding with tap hole 6; Described inverter 3 be arranged on described tap hole 6 corresponding directly over, and be connected with frame 8 by inverter journal stirrup 7.
The utility model is work like this: by control panel 9 ato units 5, after motor 5 work, fan 4 constantly rotates under the drive of motor 5, the fan 4 that rotates sucks cool air, cool air draws dish 12 to enter into fan 4 through air-inlet grille 10, wind scooper 2, startup successively, and fan 4 blows to motor 5 with the cool air that sucks, to motor 5 coolings, after the heat of cool air and motor 5 carries out heat exchange, discharge by baffler 14 assemblies, air discharge grille 13.Be inhaled in the process of fan 4 at cool air, when cool air the time through wind scooper 2, wherein a part of cool air directly blows to inverter 3 through the tap hole 6 on the wind scooper 2, the heat that produces when making cool air and inverter 3 work carries out heat exchange, so just inverter 3 is lowered the temperature, increased the reliability and stability of unit overall work.
Because change has taken place in the position of inverter 3, the shorten length of the unit integral body that makes, the unit space availability ratio of inner is improved, and has reduced the boundary dimension of unit.
