Description
Technical field
The utility model relates to high heat radiation density machine room heat extraction field, particularly a kind of airtight heat extraction rack.
Background technology
In machine room, the integrated density of rack server is more and more higher, and the caloric value of server is increasing, and in order to guarantee that in high heat radiation density machine room, server is operated under optimum ambient temperature, high heat radiation density machine room heat extraction mode also changes at development at present.
High heat radiation density machine room heat extraction at present mainly contains following three kinds of modes:
First precision air conditioner accurate air-feeding, the indoor employing of this mode machine room air channel directly causes server cabinet by the cold wind of precision air conditioner, major advantage is to have realized that cold wind directly causes server cabinet, make rack server air intake under comparatively ideal low-temperature condition, shortcoming is that blower fan need to be selected the large pressure head blower fan that can overcome duct resistance, therefore the blower fan power consumption is larger, has brought the precision air conditioner power consumption larger thereupon; In addition, adopt this mode heat extraction, because of the cold in air channel, distribute uneven on the one hand, can not effectively solve machine room hot localised points problem, far and near different apart from the precision air conditioner return air inlet because of server cabinet exhaust outlet in machine room on the other hand, easily produce remote rack air draft return air and freely do not make the hot localised points problem of machine room local ambient temperature higher than set point.
It two is the modes that adopt air-conditioning between row, and between row, air-conditioning has the employing direct-evaporation-type, and the freezing ability of swimming of employing is also arranged, and is arranged in the centre of two racks, realizes refrigeration nearby.Between row, air-conditioning is because being arranged between two racks, so compare than precision air conditioner, its air-supply transmission range is near, without selecting the large pressure head blower fan that power consumption is large, also, because of near the thermal source refrigeration, has solved to a certain extent hot localised points problem in machine room.But between row, air-conditioning effectively reaches the server cabinet air inlet for ensureing its air-supply, its return air effectively absorbs the air draft of server cabinet high temperature, just need to be completely cut off by certain peripheral channel, the setting of peripheral channel, having improved between row in the anthropogenic heat effect, increased floor space and cost and dropped into.
It three is to adopt the refrigerating cabinet door to substitute the heat extraction mode of the front and back door-plate of rack in machine room, adopt the refrigerating cabinet door to be divided into and adopt water cooling heat exchanger refrigerating cabinet door and adopt freon heat exchange of heat pipe refrigerating cabinet door mode, thereby two kinds of modes have all realized close server thermal source cooling effect nearby, because water cooling heat exchanger refrigerating cabinet door has the shortcoming that water is introduced machine room, so adopting freon heat exchange of heat pipe refrigerating cabinet door mode is more satisfactory selection at present, but two kinds of modes all need heat exchanger is integrated on the server cabinet door-plate, now the increase of door-plate weight is higher to the reliability requirement of frame load-bearing and hinge.
Summary of the invention
