FIELD: electric engineering; distribution cabinets.
SUBSTANCE: device unit has at least one distribution cabinet and one cooler. Cabinet has closed internal space where electric built-in modules are disposed. Cooler is attached in area disposed in vertical to front side of side surface of cabinet and lasts for at least of part o its height to communicate with internal area through at least one air-taking unit and at least one ventilation opening. Cooler has receiving camera; at least one heat exchanger is disposed in receiving camera. To make cooler easily adaptable to changing requirements of cooling, receiving camera of cooler is divided at least at separate parts to two and more partial receiving departments, disposed one above other, and cooling module is disposed in at least one partial receiving compartment.
EFFECT: widened operation capabilities; ability of replacement of cooler.
