Description

A parallel flow heat matching air supply device for IDC cabinets

technical field

The utility model relates to a practical device in the technical field of air-conditioning engineering, in particular to a parallel flow heat matching air supply device for an IDC cabinet.

Background technique

The IDC cabinet is a cabinet used to place user server equipment. Each server is placed flat on the vertically evenly arranged brackets in the cabinet. When working, the server is a heating body and needs to be cooled to ensure its safe and reliable operation. At present, there are two cooling air supply methods: first, the upward air supply method, the cold air is sent from the upper air outlet of the room, and the air flow passes through the upper space and reaches the front door of the cabinet. Inflow, then flow through the heat dissipation surface of each layer of servers, and finally flow out from the back door hole to take away the heat of the server; second, the downward air supply mode, the cold air is sent from the air outlet on the mezzanine floor of the room, and the air flow is directly sent to the front door of the cabinet, and then sent to the cabinet as above. The wind mode is the same, the cold air flows through the heat dissipation surface of the server to take away its heat, and the down-flow air is more energy-efficient than the up-flow air because the cold air does not pass through the upper non-working area space. However, for these two air supply methods, since the cold air sent to the front door of the cabinet has no air volume redistribution device, that is, it belongs to the unorganized air supply in the internal space of the cabinet, so it is impossible to realize the heat dissipation of the servers in each layer of the cabinet and the cooling air flow through it. The exact matching of the server will cause some layers of servers to overheat and cause an over-temperature alarm, which will affect the normal operation of the server.

Contents of the invention

The technical problem to be solved by the utility model is: to provide a parallel-flow heat matching air supply device for IDC cabinets, which can realize the control of the air supply volume of each layer and horizontal air supply, so as to achieve the cooling capacity provided by the cold air of each layer and that of each layer. The heat dissipation that the server should take away is accurately matched, so as to solve the problem of overheating of the server in some layers of the cabinet and cause an over-temperature alarm.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: it includes an IDC cabinet (1), and after the front door of the IDC cabinet (1) is removed, a front static pressure box (2) is connected, and the front static pressure box (2) The pressure box (2) is provided with parallel left vertical flat plates (4) and right vertical flat plates (5).

Corresponding flow passages (6) are opened between the left vertical flat plate (4) and the right vertical flat plate (5) facing each layer of servers.

A split air valve (7) is fixed at the left end of the flow channel (6), and a horizontal louver air port (8) is fixed at the right end of the flow channel (6).

The bottom surface of the front static pressure box (2) is provided with a lower air supply port (3).

The beneficial effects of the utility model are:

The beneficial effects after installation and use of the device are as follows: first, the cooling capacity matches the heat dissipation capacity, so as to avoid the occurrence of an over-temperature alarm. The cold air from the down-supply pipe on the ground interlayer of the room enters the plenum through the down-supply port at the bottom of the pre-static plenum, the cross-sectional area of the air flow increases, the air velocity decreases, and the dynamic pressure is converted into static pressure, which advantageously ensures The air static pressure at the front end of the servers on each floor is basically equal, which creates conditions for the organized and uniform air supply of the server channels on each floor. When the heat dissipation of the servers on each floor is the same, the half-open air valves are kept fully open, and the cold air from the static pressure box flows through the fully open air valves and the horizontal louver air supply ports through the channels opened on the two parallel plates to realize the air distribution of each server floor. Parallel air supply air evenly, and use the selected air supply temperature difference to supply air, so as to obtain an accurate match between the cooling capacity of the cold air on each floor and the heat dissipation of the servers on each floor, and avoid the occurrence of over-temperature alarms caused by overheating of individual servers; When the heat dissipation of the electronic components of the server is different between the layers, it is only necessary to adjust the opening of the valve leaf of the split air valve to change the air supply volume, and the required cooling capacity and the required heat dissipation of each layer can also be achieved. To avoid the phenomenon of over-temperature alarm. Second, the local organized air supply avoids too low air supply temperature and reduces the energy consumption of the cooling machine. Cooling and cooling of servers on each floor of the original IDC cabinet is a local unorganized air supply. Due to the unorganized or uncontrollable flow of cold air in the server channels of each layer, in order to ensure that the most unfavorable server layer does not overheat, it is necessary to reduce the air supply temperature. , so that the temperature difference of the entire supply air of the air conditioning system must be reduced, so the energy consumption of the chiller increases. After adopting the device, the local organized air supply is realized, and the cooling capacity of each layer can be supplied on demand, thereby reducing the energy consumption of the cooling machine and obtaining an energy-saving effect.

Detailed ways

In view of the disorganized air supply situation of the servers on each layer of the original IDC cabinet 1, the utility model is equipped with a parallel flow heat matching air supply device to realize organized air supply and match cold and heat to avoid overheating alarms on individual server layers. The specific method is to connect the front static plenum box 2 to the IDC cabinet 1 closely through the frame cardan connection at the position where the front door of the IDC cabinet is removed, and a Two parallel vertical left flat plates 4 and right flat plates 5, between the left flat plate 4 and the right flat plate 5 are provided with a flow channel 6 facing the servers on each floor, and a split air valve 7 with the function of adjusting the air volume is installed at the left end of the flow channel 6 , the horizontal louver air supply port 8 with uniform horizontal air supply function is installed at the right end of the flow channel 6, the number of the split air valve 7 and the horizontal louver air supply port 8 is equal to the number of server layers in the IDC cabinet 1, and the bottom of the plenum box is open There is a down-supply air outlet 3. In this way, the cold air enters the front static pressure box 2 from the lower air supply port 3, and then flows through the channels opened on the two parallel plates through the split air valve 7 with adjustable air volume and the horizontal louver air supply port which plays the role of equal flow and horizontal air supply. 8. In an organized way, the required cold air is sent into the server channels of each layer, and flows through the surface 10 of the server placed on the server bracket 9, taking away the heat dissipation that should be removed. The back door 11 of the hole is discharged to ensure that the server runs at a normal working environment temperature.
