    摘要： A safety device for preventing internal combustion from developing outwards, comprises a sampling circuit, a detecting and monitoring circuit a low voltage reference source. The sampling circuit comprises two thermal detectors. The detecting and monitoring circuit comprises a first monitoring terminal and a second monitoring terminal. The monitoring outputs of the first and the second monitoring terminals according to the situation of the thermal detectors is as follows: in the case of the two thermal detectors are in normal station, the first and the second monitoring outputs are inactive; in the case of one of the thermal detectors is in fault, the first monitoring output is inactive and the second monitoring output is active; in the case of the two thermal detectors are in fault, the first and the second monitoring outputs are active. The first monitoring output is used to open a power source of a fan and the second monitoring output is used to drive an alarming unit.

    摘要： The disclosure provides a cabinet temperature control apparatus, processing apparatus, system and method. The cabinet temperature control system includes a cooling vent path (10) provided with an air inlet (15) and an air outlet (14), and a reflow-mixing vent path ( 20) provided with a circulating air inlet (14) and a circulating air outlet (15), and/or a cabinet temperature control processing apparatus. The circulating air inlet (14) and circulating outlet (15) of the reflow-mixing vent path (20) are respectively communicated with the air outlet (14) and air inlet (15) of the cooling vent path (10), and a circulation fan unit (23) and an environment fan unit (21, 22) are provided in the reflow-mixing vent path (20). The cabinet temperature control processing apparatus is used to control the temperature and relative humidity of the system within an allowable range for normal operation of the equipment arranged in the cabinet. The present invention may be applied to various outdoor environments without the need to an additional heater under normal temperature environment. The interior relative humidity of the equipment may be reduced by self-heating using heat consumption of equipment itself, which can suppress corrosion, save energy and ensure reliable cooling.

    摘要： A technique for cooling equipment racks that contain multiple individual devices, such as computers, that each have their own internal cooling fans. An air passage ('shunt tube') is placed between a compartment inside the rack, and the ambient air outside the rack, or between compartments inside the rack. Sensors inside the air passage detect movement of the air inside the passage, and thus indirectly measure the presence of a differential pressure. The preferred sensor embodiment uses temperature sensors, and takes advantage of the differences of the air temperatures inside the computer rack, and outside the computer rack (or between internal computer rack compartments) to determine if the air is moving through the air passage, and which direction the air is moving. In response to the measurements, a control system is configured to drive the plenum to a slight vacuum, and then slowly reduce an exhaust fan until the plenum is slightly pressurized, at which point the fan speeds up and again creates a slight vacuum. This allows the rack enclosure to continuously adapt to any changes in cooling requirements, as the computer utilization changes.
