Electrical cabinet with improved heat dissipation

An electric cabinet designed to receive removable electric functional units, said electric cabinet comprising:

• a front panel;
• a rear panel;
• a top panel;
• a bottom panel;
• and
• a separating partition delineating:
• a first thermal area formed by a first space located closer to the front panel than the rear panel of the electric cabinet, said first thermal area being designed to receive first electric apparatuses or parts of the first electric apparatuses of the removable electric functional units, the front panel, the top panel, the bottom panel and the separating partition enclosing the first space, and
• a second thermal area formed by a second space located closer to the rear panel than the front panel of the electric cabinet, said second thermal area being designed to receive second electric apparatuses or pans of the second electric apparatuses of the removable electric functional units, the rear panel, the top panel, the bottom panel and the separating partition enclosing the second space, wherein
• the separating partition comprises the removable electric functional units,
• the electric cabinet further comprises a cooling and regulating device of temperature of the first and second spaces, said cooling and regulating device comprising:
• an air-conditioner positioned in contact with the first space of the first thermal area to cool the first space without being in physical contact with the second space of the second thermal area, the air-conditioner being positioned within the front panel;
• and
• a computer controlled actuator that is designed configured to be operated to allow air to flow from the first space to the second space to cool the second thermal area with air from the first thermal area when a measured temperature of the second thermal area is higher that the critical operating temperature of a most sensitive apparatus of the second electrical apparatuses or parts of the second electric apparatuses, the actuator being positioned in the separating partition of the electric cabinet, the actuator being positioned closer to the bottom panel than the top panel.
