Description

A kind of heat pipe back plate type data center
Technical field
The present invention relates to data center fields, and in particular to a kind of heat pipe back plate type data center.
Background technology
In recent years, two big projects of data center's heat dissipation:The heat dissipation problem of high fever density occasion and how to realize in data Heart energy-saving run.
In terms of high heat density:In recent years, with the development of data center, the heat density of the single cabinet of data center is increasingly Height reaches 20kW/ cabinets, even higher, has been difficult solution using traditional direct-expansion type air conditioner in machine room or chilled water air conditioner in machine room The heat dissipation matters of certainly this kind of high heat density computer room, it is easy to locally generate hot spot.
In terms of energy consumption, with the development of data center, heat is bigger, and air quantity accordingly also can be bigger, and existing computer room is empty Adjusting system is all made of the heat management mode of control computer room bulk temperature, and heat transfer temperature difference is relatively small, and heat exchange efficiency is low.Using shortening The method of cooling distance can increase heat transfer temperature difference, effectively improve cooling and heat exchange efficiency, excavate the consumption reduction potentiality of air-conditioning system.
There are mainly two types of the methods of the shortening cooling distance used in information machine room at present:
One is accurate air-feedings, are fed directly to the cold wind of air-conditioning system by specific air duct to need the cabinet of cooling, increase The cold temperature difference is sent, the wind pushing temperature of air-conditioning cooling can be properly increased, to improve the overall performance of air-conditioning system.The main of this method lacks Point is that the wind turbine of air-conditioning system is needed to provide larger pressure head, and which increase the transport energy consumptions of air-supply, in addition, the air quantity in air duct Distribution is not easy to adjust.
One is distributed refrigerations, and the evaporator of air-conditioning system is designed to several evaporation pans, by small-sized evaporation Device is placed at the exhaust outlet of cabinet, and the cold that can effectively reduce air-conditioning system in this way dissipates, cooling on demand.But due to pager Cabinet distribution is more intensive in room, and the pipeline load and refrigerant flow for be easy to causeing air-conditioning system in this way are not easy to adjust Control, control system are complex;In addition, the information machine room energy-saving effect that this method is less for heat dissipation amount, calorific value is larger It is less apparent.
Invention content
Goal of the invention:For above-mentioned existing problem and shortage, the object of the present invention is to provide a kind of heat pipe backboards Formula data center and its implementation solve the heat dissipation problem of high heat density cabinet, and cooling is more efficient, energy consumption is lower.
For achieving the above object, the technical solution adopted by the present invention to solve the technical problems is:A kind of heat pipe back of the body Board-like data center includes the backboard air-conditioning and multiple wind turbines of multiple cabinets and cabinet corresponding number;Before multiple cabinets Two rows of composition cabinet groups, front-seat cabinet group are arranged side by side with heel row cabinet group afterwards;Each backboard air-conditioning is pacified respectively On the back door of corresponding each cabinet;The front row cabinet group is placed back to back with heel row cabinet group, i.e., at front row A cold passage is formed among backboard air-conditioning on backboard air-conditioning and heel row cabinet group in cabinet group;Front-seat cabinet group With closing caping is installed at the top of the cold passage among heel row cabinet group, be provided with multiple assemblings on the closing caping Mouthful, the wind turbine is separately mounted on the assembling mouth on sealing caping;Among front-seat cabinet group and heel row cabinet group Cold passage rear and front end preceding end door and rear end door are installed;In this way, backboard air-conditioning is mounted on cabinet back door, produce by boasting from cabinet Hot wind, the heat exchanger for being directly over backboard air-conditioning cooled down, and cooling wind enters suction of the cold passage through wind turbine and is sent into big ring In border, so that the discharge colder gas recirculation of cabinet enters cabinet to Electronic cooling.
Further, the front-seat cabinet group and the cabinet door of heel row cabinet group are placed face-to-face, i.e., often arrange cabinet Closed cold passage is collectively formed with closed roof, preceding end door and rear end face respectively in group;In this way, backboard air-conditioning is mounted on cabinet Back door, the cold wind that wind turbine sucks in overall situation are sent into cold passage, and cold wind respectively enters cabinet to Electronic cooling through cold passage, The hot wind produced by boasting from cabinet, the heat exchanger for being directly over backboard air-conditioning are cooled down, to by backboard air-conditioning discharge compared with Cold gas recirculation enters overall situation.
Further, the backboard air-conditioning includes heat exchanger, Temperature Humidity Sensor and control unit;Heat exchanger can be Finned tube exchanger can also be micro-channel heat exchanger.
Further, the backboard air-conditioning of two neighboring cabinet is separately connected two different low-temperature receivers.Often arrange the back of the body of cabinet Plate air-conditioning is connected to according to single double serial numbers on two different cold source systems;When one of backboard or a cold source system When breaking down, adjacent backboard can take away the heat of the cabinet where failure backboard, play the role of intersecting backup.
Further, front-seat cabinet group connect side by side successively with multiple cabinets of heel row cabinet group, and neighboring cabinet Between to gang up design, to be conducive to air-flow crossfire, and only outermost cabinet is equipped with sealing side plate and is used to seal.
Further, the backboard air-conditioning is rotatably installed in the side at the back door of cabinet, then can door rotation and rotate.
Further, the wind turbine is stepless speed regulating blower fan, on the one hand, can be according to load variations automatic speed regulation, to protect On the other hand card, can play the function of mutually backing up, when certain Fans breaks down with energy-saving run at low load When, other wind turbines can supplement air quantity, meet refrigeration demand by way of increasing rotating speed automatically.
Further, electronic equipment is housed in the cabinet.
Advantageous effect:Compared with the existing technology, the present invention has the following advantages:Backboard air-conditioning utilizes the principle of heat pipe, peace Back door loaded on cabinet, air-conditioning directly close to cabinet, will effectively solve the above problems:1) heat dissipation for solving high heat density cabinet is asked Topic, backboard air-conditioning can provide solution for the occasion of 20kW/ cabinets at present;2) cooling scheme close to cold source type is used, Flat small wind turbine changes the big wind turbine of unified high efficiency into, and power of fan reduces up to 75%;3) using the cooling close to cold source type Method, return air temperature improve, and heat exchange efficiency also accordingly increases;3) backboard air-conditioning heat exchanger and wind turbine separately design, and backboard is empty Adjust thinner, occupation of land smaller.
