摘要:
A cooling system includes an electronic enclosure and a liquid-cooled heat exchanger configured to receive heated air from within the enclosure. A geothermal loop is connected to the heat exchanger to form a closed-loop path. The closed-loop path is suitable for circulating a pressurized liquid refrigerant between the geothermal loop and the heat exchanger to transfer heat from the heated air to the geothermal loop without the refrigerant undergoing a phase change.
摘要:
A passive cooling system for cooling an enclosure containing electronic components. A hollowed portion of the enclosure is formed as an integral heat pipe containing a working fluid. The hollowed portion has an evaporator section located at the top and a condenser section located at the bottom. The enclosure also has hollowed side walls which serve as passage ways for the working fluid to flow through in between the evaporator and condenser sections. Gravity and the pressure of evaporation force the working fluid down to the condenser section. A wick is provided for returning the working fluid to the evaporator section by capillary action. Additionally, an ultrasonic transducer driven by the heat rejected from the condenser section may be used to help return the working fluid to the evaporator section. Finally, a check valve may be employed before the evaporator section for the working fluid to flow through.

An integrated type air conditioning device includes a first refrigeration cycle that is an evaporative cooling type, a second refrigeration cycle that is a vapor-compression type, a blower device, and a housing accommodating the first and second cycles. The first refrigeration cycle includes an evaporation heat exchanger, a condensation heat exchanger, and a first refrigerant pipe. The second refrigeration cycle includes a compressor, a condenser, a decompression device, an evaporator, and a second refrigerant pipe. The housing is partitioned into an interior air passage and an exterior air passage. The evaporation heat exchanger and the evaporator are positioned in the interior air passage, the evaporation heat exchanger being located upstream of the evaporator with respect to an interior airflow in the interior air passage. The blower device is disposed in the interior air passage and is driven to generate the interior airflow in the interior air passage.

An electrical room housing electrical and electronic apparatus for operating and controlling electrical motors of an industrial equipment is disclosed. The electrical room includes a cooling device with a first heat exchanger which is arranged with a first set of channels through which is conducted a first flow of air drawn from inside the electrical room. Warm air from inside the electrical room is circulated through the first heat exchanger of the cooling device and returned to the electrical room in a closed loop, and the air temperature in the electrical room is controlled dependent on a setpoint of between 24-40° C. A method for controlling the cooling device to cool the electrical room and one or more computer programs arranged for controlling the cooling device are also described.
