High reputation Ip55 Cabinet Air Conditioner - Thermosiphon Heat Exchanger for Telecom – BlackShields

Brief Introduction

BlackShields HM series DC Thermosiphon Heat exchanger is designed for controlling the climate of indoor/outdoor cabinet in challenging indoor and outdoor environments. It is a passive cooling system which utilizes the phase-shifting energy to cool down the inside of the cabinet. It effectively solves the heat problem of outdoor cabinet and is widely used in indoor and outdoor cabinets and enclosures with sensitive electronic equipment.

This unit fully utilizes nature indoor and outdoor temperature difference. The internal enclosure temperature is cooled via effective utilization of refrigerant evaporation. The passive heat exchange is based on the natural convection, which circulates liquid in a vertical closed loop circuit without requiring a conventional pump or compressor.

Application

•   Telecom cabinet      •   Renewable energy

•   Transportation         •   Power Grid

Features, Advantages & Benefits

•   Energy Efficiency

  –   Passive cooling system uses the thermodynamic method of passive heat exchange based on internal natural convection.

  –   Similar design with Air conditioner, with condenser and evaporator which is designed by Micro-Channel technology, but without Compressor, using 48VDC fans, speed adjustable with long life time and minimal power consumption for energy saving.

    –   Aluminum Micro Channel Condensor and evaporator, more efficient.

•   Easy installation and Operation

  –   Compact, mono-block, plug and play unit to ensure easy installation;

  –   Closed loop cooling protects equipment against dust and water;

  –   Constructed of sheet metal, powder coated with RAL7035, excellent anti-corrosion and anti-rust properties, endure hash environment.

•   Intelligent Controller

  –   Multifunction alarm output, real-time system monitoring and convenient human-computer interface;

– RS485 & dry contactor

  –   Self-recovery, with multi protection function.
