Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. Example one
Fig. 1 is a schematic structural diagram of a server rack according to a first embodiment of the present invention. Currently, at least one server 100 is included in a server rack, and each server 100 has a fan corresponding to it. A certain amount of heat is generated during the operation of the server 100, and the heat generated from the server 100 may be transported to the hot air discharge port 102 based on the fan 101 disposed opposite to the server 100. In order to further realize the cooling of the environment in the cabinet, a cold air inlet valve 103 is further arranged in the server cabinet, and cold air can be introduced into the server cabinet based on the cold air inlet valve 103. Certainly, in order to accelerate the cooling of the server cabinet, the mixed gas inlet valve 104 is further arranged, so that the heat in the cabinet is accelerated to move based on the gas introduced by the mixed gas inlet valve 104, and the temperature in the server cabinet is rapidly reduced.

Wherein the cold air inlet valve 103 is used for transporting cold air to the inside of the server cabinet; the hot air outlet 102 is used for guiding heat generated by the server inside the server cabinet to the external environment; the mixed gas inlet valve 104 is used for introducing mixed gas into the inner wall of the server cabinet so as to accelerate the transportation of heat generated by the server inside the server cabinet to the hot air outlet.
Wherein, be provided with cold air admission valve 103 on the outer wall of server rack, in order to transport cold air in the server rack, can be based on the breather pipe with cold air admission valve 103 and refrigerator be connected to the cold air that makes the refrigerator is led into the inside of server rack through breather pipe and the cold air admission valve 103 that sets up on the server rack. And the hot air outlet 102 is arranged on the outer wall of the server cabinet and is used for exhausting heat in the cabinet from the hot air outlet 102 so as to reduce the ambient temperature in the cabinet. Further, in order to accelerate the rapid transportation of heat in the server rack to the hot air exhaust port or the circulation of cold air in the server rack, a mixed gas intake valve 104 may be provided. The mixed gas inlet valve 104 may be disposed at any position on the outside of the server cabinet, and it is only necessary to determine that the mixed gas can enter the server cabinet through the mixed gas inlet valve.
On the basis of the above technical solution, in order to quickly reduce the heat in the server cabinet, at least one heat exchanging device 105 is further disposed inside the server cabinet, see fig. 2. At least one heat exchange device 105, disposed on the barrier plate inside the server cabinet, for exchanging heat between heat inside the server cabinet and heat of the external environment; the bottom area of the baffle plate is the same as the bottom area of the cavity of the server cabinet, is arranged opposite to the bottom of the server cabinet, is used for dividing the cavity of the server cabinet into at least two parts, and is used for supporting at least one heat exchange device 105 arranged in the server cabinet.

The heat exchanging device 105 is used for conducting heat in the server cabinet to the external environment, and is also used for conducting cold air into the server cabinet after conducting treatment. The heat exchange device 105 is disposed on the barrier plate.

Alternatively, at least two heat exchange devices 105 are disposed opposite to the cold air intake valve 103 and the hot air exhaust port 102, respectively.
Specifically, at least two heat exchange devices 105 may be disposed on the barrier plate, and the heat exchange devices are disposed opposite to the cold air intake valve and the hot air exhaust port, respectively, for rapidly achieving a rapid temperature reduction in the server cabinet based on the heat exchange devices.
To improve the efficiency of reducing the ambient temperature within the server rack, the mixed gas may be introduced based on the mixed gas inlet valve 104. The mixed gas may be a mixed gas of helium and air, and the mixing ratio may be 7: 3. The advantages of using a helium and air mixture are: helium belongs to inert gas, is relatively stable, is not easy to react with other substances, and can effectively protect electronic components of the server from being oxidized; furthermore, helium is lighter than air, so that air circulation in the cabinet can be accelerated, and the heat dissipation efficiency is improved.

The upper surface of the first chamber 107 is a heat shield disposed opposite the bottom surface of the chamber, and the heat shield has a heat exchanging device 105 disposed thereon. The side of the first chamber and the floor form a closed first chamber 107 based on the heat exchange means 105. The control formed between the outer wall of the first cavity 107 and the inner wall of the server cabinet serves as a second cavity 108 of the server cabinet, and the other end of the heat exchange device 105 is arranged opposite to the cold air inlet valve 103 and the hot air outlet 102 of the first cavity.

It should be noted that each server in the server cabinet needs to work in a suitable environment, that is, the temperature in the server cabinet should not be too high or too low, so that a temperature sensor is needed to detect the temperature of the cavity, and then the valve opening of the cold air inlet valve is adjusted, thereby achieving the technical effect of adjusting the ambient temperature in the server cabinet.
Alternatively, referring to fig. 4, a first temperature sensor 109 is disposed in the first chamber 107, and configured to detect a first chamber temperature and send the first chamber temperature to the controller, so that the controller adjusts the valve opening of the cold air intake valve 103 based on the first chamber temperature; or, the second temperature sensor 110 is disposed in the second cavity 108 and configured to detect a second cavity temperature and send the second cavity temperature to the controller, and the controller adjusts the valve opening of the cold air intake valve 103 based on the second cavity temperature; or, a first temperature sensor 109 and a second temperature sensor 110 are respectively arranged in the first chamber 107 and the second chamber 108, the first temperature sensor 109 is used for detecting the temperature of the first chamber in the first chamber 107, the second temperature sensor 110 is used for detecting the temperature of the second chamber in the second chamber 108, and the controller adjusts the valve opening of the cold air intake valve 103 based on the received first chamber temperature and second chamber temperature.
That is, a temperature sensor may be provided in the first chamber 107 and/or the second chamber 108 to detect the temperature in the chambers, and then send the detected temperature to the controller corresponding to the server cabinet.
