Heat pipe technology has been widely used in aerospace, military industry, petroleum, chemical industry, metallurgy, machinery, electric power, electronics, coal, railway, communication, textile, home appliances, IT products, and many other fields. Traditional engine heat removal equipment, air conditioning, fresh air, heat pipe, ethylene glycol, etc.) has a characteristic, is the first room space cooling, and then through the room appropriate air temperature to cool the engine room equipment, this kind of indirect way we will be referred to as district cooling.
New way is the direct discharge of heat absorption equipment, make the room equipment to minimize the emission quantity of heat, room temperature will not be because of a large amount of heat removal of power supply, rise, will greatly solve the machine room of existing many problems:
All of the thermal conductivity and heat exchange equipment all have a common, namely hot absorption and row hot temperature difference, the greater the thermal conductivity, the higher the efficiency of the heat transfer, computer room equipment is the heat of the engine room, outlet air temperature tends to equipment above 50 ℃ or higher, equipment inside part of the chip temperature even can reach above 100 ℃. This temperature difference, eliminate the high temperature hot spots can be much easier and more efficient than the lower space temperature and lower investment.
Circulating wind temperature closer to the computer room equipment room equipment cycle into the wind temperature, small to air flow requirement, can sharply cut machine room air volume and air pressure. , imagine if work of power supply, heat removal in the initial stage (before failed to affect the temperature of the surrounding environment) has been conducted in the outdoor, discharge air temperature was close to equipment needs, so big air volume high wind pressure for machine room, lost the main meaning of existence.
In order to meet the requirements of lower the temperature in the room space, district cooling equipments have to be required for all kinds of components in a reasonable way to integrate, to become a air conditioning, due to the special purpose equipment room dedicated air conditioning, by far the most sophisticated design also can only do include maintenance station 20 kw per square meter covering (indoor) show the target of cold quantity. And using point by point by means of heat transfer due to the need to fan, while each heat transfer terminal can be very small and can be integrated into the top of the cabinet corner,, cupboard door position such as cracks, equipment internal, connection can rack installation in the cabinet at the top and bottom of the line. In practical use, do not need to separate individual reserved for heat exchange equipment using area, also do not need too much room reserved space specially for connection.
Existing technology can easily accommodate equipment cabinet to achieve very high heat absorption, more can be easily expanded.
On hot chip installed heat pipe heat absorption end, after all hot chip endothermic terminal equipment into parallel interface reserved to external equipment, with the cabinet reserved gas, liquid pipe connected in parallel to the outdoor heat exchanger, can directly make hot chips and room air heat transfer from the outside. Due to the characteristics of heat pipe heat absorption end can heat the temperature of the contact surface is more close to the boiling point of the liquid inside, the data can be achieve cooling of outdoor environment temperature), therefore, under the existing conditions can let the machine room equipment operating temperature is much lower than before the chip work temperature, further improve the reliability of computer equipment. At the same time, for reducing the exhaust temperature equipment parts, reduce the equipment failure point, reduce the energy consumption of equipment, easier to use a stronger performance chip, so we expected, equipment providers is also very willing to make that match.
