Technical Field

For the frequency conversion integrated water chilling unit, because the water chilling unit is placed outdoors, the water chilling unit is externally made into a shell for protection by adopting metal plates, and because the water chilling unit is exposed to the sun for a long time in summer, the temperature in the shell is higher, and when the ambient temperature reaches 40 ℃, the capacity of the frequency converter is reduced, so that the water chilling unit cannot reach full load. The existing water cooling unit generally adopts the following two methods for heat dissipation: the first method is that through correspondingly arranging ventilation grids on two opposite side walls of the shell, the heat of the shell is discharged to the outside by utilizing air convection, but the method can only automatically discharge the heat through the ventilation grids, the external environment temperature in summer is higher, and even if the heat in the shell is dissipated, the heating component cannot be cooled well; the second method is to install an exhaust fan on the water cooling unit to exhaust the heat of the shell, and although the heat in the shell can be exhausted, the heat radiation effect is still not good, and when the external environment temperature is high, the temperature in the water cooling unit is reduced, and the influence on a frequency converter and the like still exists.
