[0001] The utility model relates to the technical field of heat dissipation of computer room equipment, in particular to computer room equipment. Background Art
[0002] In computer room equipment, for example, standard cabinets in data center computer room equipment data center are based on U as the basic unit, which is an internationally accepted unit of measurement for the external dimensions of modular racks, 1U = 1.75 inches = 44.45mm. The height of a standard server is usually an integer multiple of U, and needs to occupy a corresponding number of U positions in the cabinet.
[0003] As an accessory between two adjacent servers, the cabinet blind panel is used to cover the empty U position of the server shell. It is used as a baffle to isolate the hot and cold channels. There are many specifications such as 1U and 2U. Commonly used cabinet blind panels are 1U and 2U.
[0004] Considering the actual operation and maintenance management issues such as heat dissipation, wiring and power limitation of equipment in the computer room, a U space is usually left empty between two adjacent servers in the equipment room. Figure 1 As shown, for the vacant U position, a cabinet blind panel 04 needs to be installed in front of the server housing 01 to isolate the hot and cold channels.
[0005] However, the design or product of the traditional cabinet blind panel 04 will cause the top of the server, that is, the second air inlet 0103 on the side of the server shell 01 to be exposed to the heat channel when actually used. The gas sucked in by the fan 03 in the server is a mixture of the cold air from the first air inlet 0102 in the front and the hot air from the second air inlet 0103 above, which seriously affects the heat dissipation effect of the server.
[0006] At the same time, since the second air inlet 0103 is usually arranged at the top of the server housing 01 and is always in an open state, impurities enter the device accommodating cavity through the second air inlet 0103, thereby interfering with the operation of the device accommodating cavity, resulting in reduced safety of server use.

[0040] The utility model embodiment discloses a computer room device, which can improve the heat dissipation effect of the server and the use safety of the server at the same time.

[0043] Specifically, a ventilation cavity is provided in the cabinet blind plate 4, and an air guide inlet 401 and a first air guide outlet are provided in the cabinet blind plate 4, and the first air guide outlet is connected to the second air inlet 103 and the ventilation cavity. The cabinet blind plate 4 includes a rear baffle 403 connected to the side of the server housing 1, the rear baffle 403 isolates the second air inlet 103 and the air outlet, the air guide inlet 401 faces the front end of the server housing 1, and the air outlet 104 and the first air guide outlet are located on opposite sides of the rear baffle 403.
[0044] The damper 5 is rotatably mounted on the air guide inlet 401, and has a closing position for closing the air guide inlet 401 and a ventilation position for opening the air guide inlet 401. When the second air inlet is not needed to take in air, the damper 5 is closed and is in the closing position.
[0045] The opposite ends of the damper 5 are rotatably mounted on the cabinet blind plate 4 through the pin shaft 405, and when the damper 5 is switched from the ventilation position to the closed position, the damper 5 can return to its original position by its own gravity. Specifically, at this time, the opening of the damper 5 can be opened by the push of the cold air flow. Specifically, when the damper 5 is set horizontally, the air guide inlet 401 is fully opened.
[0046] Specifically, the rotation axis of the damper 5 coincides with the center line of the air outlet 104. Of course, during specific assembly, the rotation axis of the damper 5 may be higher than the center line of the air outlet 104 and coincide with each other.
[0047] Specifically, the thickness of the cabinet blind panel 4 is an integral multiple of 1U, so as to be installed exactly between two adjacent server casings 1 .

[0053] It can be known from the above description that in the computer room equipment provided in the specific embodiment of the present application, the air outlet 104 is isolated from the second air inlet 103 by the rear baffle 403 of the cabinet blind plate 4, so that the cold air can enter the device accommodating cavity through the second air inlet 103, avoiding the situation where the hot air flow through the device accommodating cavity flows back to the device accommodating cavity through the second air inlet 103, therefore, the computer room equipment provided by the present application improves the heat dissipation effect of the server. At the same time, the damper 5 is provided, and the air guide inlet 401 can be closed as needed, thereby avoiding the situation where impurities enter the device accommodating cavity through the air guide inlet 401, the ventilation cavity, the first air guide outlet and the second air inlet 103, thereby improving the safety of the server.
