Description
Technical field
The present invention relates to server cabinet, be specifically related to a kind of data center server cooling machine cabinet that can realize transmission of heat by contact.
Background technology
Along with the raising of the integrated degree of server, the power of data center machine room single chassis significantly promotes.The feature of data center's high speed development and its high energy consumption is shown great attention to by society, and the data center that it is carried out to reducing energy consumption or construction high energy efficiency is significant for energy-saving and cost-reducing work.According to statistics, now up-to-date blade server frame power is up to 15kW, and desk-top server rack power is 1.5kW, and modular server rack power is 5kW.High power consumption certainly leads to high heating, and this becomes terribly local pyrexia, and thermograde changes greatly, and aeration-cooling processing is complicated.The shutdown of air-conditioning short time or refrigerating capacity deficiency, computer room temperature can be elevated to rapidly ultimate temperature, causes server all to report to the police and even shut down.Show according to related data, there is nearly 33% the machine room Zeng Yinwei air conditioner refrigerating problem machine phenomenon that occurred delaying in China.The computing machine of highly energy-consuming gets into a difficult position data center.
The heat radiation of server is the focus of industry forever, more and more higher at bulk density, today that power consumption is increasing, server, especially widely apply the data center of server, heat dissipation problem is " that waves is not loose " forever, now, because external cooling is difficult to deal with problems completely, and radiating efficiency is lower, often cause the inner local overheating of server, thereby can not reach the requirement of server radiating, so increasing manufacturer server focuses on server inside by the heat radiation of server.For server radiating, especially internal heat dissipating, simple increase number of fans or increase rotation speed of the fan can not well be dealt with problems, fan is more, and rotating speed is faster, and power consumption is also just more, noise also can be larger, and for user, power consumption and noise are also very large problems.
Therefore find and a kind ofly how drop under prerequisite in limited space and air-conditioning, ensure effective radiating effect, with realize that the quantity of rack maximizes and rack in the maximized heat abstractor of quantity of server compel at eyelashes.
Summary of the invention
The object of the invention is to solve existing server radiating problem, and provide a kind of data center server cooling machine cabinet that can realize transmission of heat by contact, this cooling machine cabinet has been realized data center server rack, energy-conservation heat transfer system and server shell integrated design, by enforcement of the present invention, realizing data center's contact conducts heat, not only improve heat transfer efficiency, and the design of phase-change heat transfer system module by this data center server cooling machine cabinet inside, reduce data center's air-conditioning power consumption.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of data center server cooling machine cabinet, is characterized in that, comprises the spring leaf (6) of a server cabinet (1), phase-change heat transfer system, server shell (5) and fixed server casing; Described phase-change heat transfer system comprises the multiple heat interchanger (2) that are installed in server cabinet, outdoor cooling device (3) and connecting line (4); Described multiple heat interchanger (2) are installed on respectively on every one deck support of placing server in described server cabinet (1); The described multiple heat interchanger (2) that are installed in server cabinet are all direct-cooling type heat interchanger; Described multiple heat interchanger (2) are together in parallel and are then connected described outdoor cooling device (3) by connecting line respectively; Described server shell (5) is positioned over the top of described multiple heat interchanger (2), and it comprises server shell base (51) and (52) two parts of server case upper cover; The base plate of described server shell base (51) and this base plate four side plates are the integral structure of casting; Described server shell base (51) is the good metal shell of thermal conductivity; The base plate interior of described server shell base (51) is cast with fluted body or convex structure according to upper larger electronic devices and components (71) planform of thermal value of server (7), and the base plate that makes described server shell base (51) and described server (7) are gone up electronic devices and components (71) that thermal value is larger can close contact; Between the base plate of described server shell base (51) and described server (7) electronic devices and components that above thermal value is less, leave space, they are discontiguous; The outside surface of the base plate of described server shell base (51) is a flat metal plates; On faying face between described server shell base (51) and server case upper cover (52), be respectively arranged with liner; The side plate of described server shell base (51) is provided with line outlet (53), ensures that the I/O mouth on server shell internal server (7) is connected with outside by described line outlet (53); The spring leaf (6) of described fixed server casing is fixed on the bottom of the last layer server rack of placing server place support, is positioned at the top of institute's fixed server; The electronic devices and components (71) that thermal value on server is larger like this contact with the base plate of described server shell base (51), heat is directly passed to server metal chassis (5), server metal chassis (5) and heat interchanger (2) close contact, heat is directly passed to direct-cooling type heat interchanger (2), the refrigeration working medium heat absorption evaporation that direct-cooling type heat interchanger (2) is inner, refrigeration working medium after evaporation is circulated to outdoor cooling device (3) and dispels the heat, then refrigeration working medium returns direct-cooling type heat interchanger, carries out next one circulation.
The above is installed on server machine multiple heat interchanger (2) is cashier's office in a shop copper aluminium coil pipe direct-cooling type heat interchanger.
