Cooling unit: The product is designed to meet the thermal management needs of indoor cabinets. It can keep the temperature inside the cabinet at 35°C at 5-55°Cexternal environment. It also adapts to various working conditions and various voltage specifications. The cooling unit adopts external circulation, and the front outlet has high permeability. The outlet adopts a unique louver design which effectively directs the hot air and avoids the vicious cycle of air caused by the short circuit of hot and cold wind. The ingenious structure design of evaporation end, keep wind and water independent two channels. The hidden danger of the electrical components in the cabinet caused by the cooling unit's flying water is greatly reduced. The control part is built in the inner cycle of the cooling unit, and the digital closed loop temperature control system can accurately control the temperature in the cabinet. The built-in fan of the cooling unit is simple and convenient to maintain. To meet the needs of high-end user customization and the demand for space, beauty and performance, we have door-mounted cooling unit. Door-mounted cooling unit can be installed together with the cabinet to achieve a complete integrated design. Under different conditions, we have the stainless-steel shell, nanoscale coating or Teflon coating, to improve the corrosion and dust resistance of cooling unit.
