Description

Air-conditioning
Technical field
The present invention relates to air-conditioning technical field, particularly relate to a kind of server in machine room air-conditioning.
Background technology
The cybertimes that modern data is concentrated greatly, the miniaturization of computer, rack, the slimming of server, blade.Their feature is that volume is more and more less, but electronic power density is but in continuous increase.Under these conditions, the refrigerating system in machine room subjects increasing test.
Cabinet air conditioner designs, as solved the heat dissipation problems such as outdoor communication cabinet, Wireless outdoor cabinet base station, storage battery cabinet for communication field application specially.Be mainly used in taking away electric component and consume the heat that electric energy sends, for all kinds of interior of equipment cabinet provides desirable humiture environment, isolate the dust in external environment, corrosive gas simultaneously, extended the useful life of electric component, improve machine system operational reliability.Product is applicable to electric control box, communication, communication equipment, data processing case and heavy motor device control cabinet etc.
Traditional cabinet air conditioner is actual is air conditioner in machine room, and it is suitable by regulating machine room bulk temperature to carry out Deterministic service device equipment operating environment temperature.But air conditioner in machine room generally places the position away from server cabinet, is blown by air supply duct, air-supply static pressure is high, and the power consumption of blower fan is high; In addition, because air conditioner in machine room regulates machine room bulk temperature, but heat the largest source system server cabinet, so in order to ensure the ambient temperature that rack server equipment runs, need the bulk temperature of machine room to regulate very low, so, the utilance of air-conditioning is reduced.
Also there is a kind of cabinet air conditioner in prior art, air-conditioner set is arranged between adjacent server by it.Such as, Chinese patent literature CN102681637A open a kind of " extensive heating server cooling machine cabinet refrigerating system ", as shown in Figure 1, it comprises server cabinet 100 and refrigerating units 200, described refrigerating units 200 is arranged between adjacent two-server rack 100, and described refrigerating units 200 comprises heat exchanger 201 and is arranged on the axial flow blower 202 of heat exchanger side.This kind of way is generally implement after server cabinet installation, because rack position is fixed, therefore has limitation when dismounting air-conditioner set, makes troubles to air-conditioning equipment installation and service work; In addition, although above-mentioned cabinet air conditioner is disembarked, cabinet is nearer, but still need the heat cold wind of air-conditioner set or rack given out to adopt the materials such as glass plate to be closed and form cold passage or the passage of heat, the mode that this cold passage or the passage of heat are closed needs additionally to increase material cost, the bulk temperature of machine room is also easily affected, need to adopt air-conditioning to lower the temperature to machine room toward contact, the bulk temperature of guarantee machine room is suitable.
To sum up, the cabinet air conditioner of prior art exists that air-conditioner set utilance is low, air-conditioner set dismounting inconvenience, high in cost of production defect, need badly and propose a kind ofly to be applicable to server in machine room cabinet air conditioner, to solve above-mentioned technical problem.
