It is and convenient for disassembly and assembly with being reliably connected for frequency converter assembly.
Preferably, the absorbent cotton layer is arranged on the inside wall of the outer housing.By absorbent cotton layer can absorb into
Enter the intracorporal water vapour of shell, has the function of moisture-proof.
Preferably, the venthole is two.It can be by heat that frequency converter assembly distributes from logical by radiator fan
Stomata blowout, accelerates the heat dissipation of frequency converter assembly.It can prevent dust from entering inside outer housing by Air Filter.
Preferably, the frequency converter assembly bottom is also connected with ground line, the ground line extends to shell across outer housing
Outside body.
Preferably, in ground line end connection ground connection inserted link.Facilitate insertion ground by being grounded inserted link, realizes frequency converter
The ground connection of component can avoid that the danger of frequency converter assembly electric leakage electric shock occurs, extend frequency converter service life, and ensure that use
Security reliability.
Preferably, being uniformly provided with several raised heat sink strips in the two sides outside wall surface of frequency converter assembly.Pass through protrusion
Heat sink strip further improves the heat dissipation effect of frequency converter assembly.
The utility model has the following beneficial effects:
The utility model structure is simple, and outer housing is installed outside frequency converter assembly, makes frequency converter assembly in use process
In, water will not be entered inside frequency converter assembly by the heat release hole on frequency converter assembly, be played to frequency converter assembly anti-well
Shield acts on the use, it can be achieved that frequency converter water environment；By the Air Filter on outer housing venthole, first pass through outside air
Enter inside outer housing after Air Filter, Air Filter avoids enter into inside frequency converter assembly the dust-filtering in air, realizes and becomes
Use of the frequency device under dust atmosphere.
