Description
Technical Field
The utility model relates to the field of air conditioning equipment, in particular to a functional air-cooled heat pump air conditioning system with a powerful electric box for heat dissipation.
Background
When the components in the air conditioner electric box work, heat can be generated, if the heat is not timely emitted, the temperature in the electric box can be increased, and the electric elements cannot work normally due to the excessively high temperature, so that the service life of the electric elements can be reduced. Most air conditioner manufacturers usually install fans in the electric boxes to force air in the electric boxes to be in convection with air outside the electric boxes so as to dissipate heat. However, there are many limitations in this heat dissipation method, such as (1) when the external environment temperature is high, the forced convection air heat exchange cannot effectively reduce the internal temperature of the electric box. (2) If the heat generated by the electrical components inside the electrical box is large, the convective air is generally unable to satisfy the heat dissipation requirement. (3) The forced convection air can bring impurities such as dust in the outside air into the electric box, and the filter screen is arranged at the air inlet of the electric box, so that the impurities can be prevented from entering the electric box to a certain extent. However, the filter screen is blocked when the electric box runs for a long time, so that the electric box cannot perform effective convection air heat exchange. (4) The air-cooled heat pump unit is usually directly installed outdoors, the sun can directly irradiate the unit in summer, and the temperature in the electric box can be rapidly increased after the electric box is irradiated by the sun. Therefore, an air conditioning system capable of ensuring the effective heat dissipation of the electric box is developed. The air-cooled heat pump air conditioning unit using the system can enable the temperature in the electric box to be stabilized in a reasonable range for a long time under various environments.
