Heat Conduction / Heat Dissipation
When the mechanical equipment is in operation, it is most afraid of the condition that the equipment overheats and causes a short circuit or destruction. [Water-cooled back door system] In addition to excellent heat dissipation performance, it can avoid the common problems that heat conduction products may face during operation. This product can be divided into two parts: [water-cooled back door (RDHx)] and [cold water dispenser (CDU)]. The first circuit of ice water is tap water, building ice water main unit, independent ice water machine, etc.; cold water distributor (CDU) provides a second circuit that can be completely isolated for temperature control; and water cooled back door heat exchanger (RDHx) Provides 100% sensible heat cooling, no condensation problems, no need to heat or humidify. Unlike previous heat transfer products, [Water-cooled back door system] emphasizes 100% space utilization, low energy consumption, zero noise, low failure and easy maintenance.

Heat Conduction Solution Water Cooling Data Center Energy Saving Water Cooling System
【Overview】 Rear Door Heat Exchanger (RDHx) is the optimal cooling design that can realize the dual-cold-aisle technology in data centers.【Scale】 Standard RDHx has a cooling capacity of 20kW/rack. The advanced RDHx can achieve a maximum of 30kW cooling capacity per rack.There are several choices of RDHx dimensions and we offer a wide range of RDHx models of 42U, 47U, and 52U height or 600mm, 735mm, or 800mm width.【Features】 It does not occupy the space of data center, and the number of cabinets is maximized. High reliability and simple structure design. No condensation water, no water tray.【Function】 The hot air that leaves the servers gets in contact with the fins and coil and the coolant absorbs the heat from the hot air immediately. This way the hot air temperature is reduced to the original rack inlet temperature.【Specification】 According to the difference of the passive/active and power, model No. is divided into RX200 / RX300 / RX216A / RX316A.
【Overview】 Cooling Distribution Unit (CDU) is the smart water cooling management unit.【Scale】 Designed with only 5U height, it can be easily placed in the standard cabinet of the server to provide water cooling function. At a flow rate of 80 LPM, the maximum cooling capacity is 80 kW.【Features】 7”color screen Easy installation and no leakage 1+1 backup pump design Water supply temperature: 15°C〜45°C Can be expanded to 100 units Support multiple communication protocols Group control【Function】 Provides the cooling needs required by water cooling device in the cabinet.【Specification】 Model No. LS80
【Overview】 Cooling Distribution Unit (CDU) is the smart water cooling management unit.【Scale】 CDU monitors the room temperature and relative humidity in the data center in real time and it immediately determines the real-time dew point. In case of any abnormal condition which causes the surge in the dew-pint in the data center, CDU will dynamically adjust the secondary supply coolant temperature to 1~2℃ above the dew point in order to make sure no condensation on the surface of the secondary pipework. CDU pumps are specially chosen to have higher flow rate with lower pump head. It has a maximum head of 50 mH2O and the actual operating pressure is only about 20~30 mH2O. Moreover, CDU is high pressure tested at 175 mH2O before shipment so that its pressure resistance is much higher than the maximum pressure that its pumps can generate.【Features】 Built-in high efficiency heat exchanger to ensure coolant quality. 1+1 spare motor design, low power consumption, no shutdown. Group control. Intelligent monitoring, no condensation inside the data center.【Function】 Provides water supply temperature for the Cooling Read Door Heat Exchanger above the dew point.【Specification】 According to different water flow and heat dissipation capacity, model No. is divided into LX360 / LX600 / LX360T / LX600T.
【Overview】 It is a water cooling management unit with intelligent temperature control.【Scale】 HCDU is equipped with highly efficient refrigeration system. An air-cooled HCDU can save up to 20% of power consumption as compared to typical air-cooled chillers while a water-cooled HCDU can save as more as 40% as compared to typical water-cooled chillers. The equivalent COP of an air-cooled HCDU is 3.74 and that of a water-cooled HCDU can be even higher at 4.76. The power consumption of HCDU is much lower than typical chillers on the market.【Features】 Monitor and control the operating conditions of the chilled water. Transmit system operating parameters to the Building Management System (BMS) for further integration. Monitor the room temperature and relative humidity in the data center in real time.
