[0020] The technical solutions of the utility model will be described below in detail in connection with the drawings. The following examples are only used to make the technical solutions of the utility model clearer, and therefore only serve as examples, but cannot limit the protection scope of the utility model.
[0021] Please refer to Figure 1 , Figure 1 The structure diagram of the heat dissipation system in the prior art is shown, in which the cabinets are arranged in rows, and refrigeration is performed by multiple precision air conditioners, so that a cold air channel is formed between the two rows of cabinets. In order to reduce the loss of the cold source, the cold air channel can be set as a closed cold pool, and the cold air in the cold air channel enters the cabinets through the air inlets of the cabinets. The equipment in the cabinets absorbs the cold air, and the cold air dissipates heat from the equipment, and then the hot air flows out of the air outlets of the cabinets and enters the hot air channel. The cold air can be sent into the closed cold pool in the form of downward air supply. For some equipment installed in reverse, that is, the air inlets of the equipment are close to the hot air channel, the direction of the air flow for heat dissipation is opposite to that of the normal installation equipment. During the operation of these equipment, the air inlets on the front of the equipment will absorb hot air from the hot air channel, and the equipment cannot effectively dissipate heat and generates high temperature.
[0022] To solve the above problems, in the first aspect, the utility model provides a wind guide device for heat dissipation of equipment in a cabinet, as shown in Figure 2 , Figure 2 The structure diagram of the wind guide device for heat dissipation of equipment in the cabinet is shown, in which one or more equipment can be installed in the cabinet 1, each equipment can occupy one rack unit or multiple rack units, and at least one equipment installed in reverse is also installed in the cabinet 1, and the air inlet of the equipment installed in reverse is close to the hot air channel, as shown in Figure 2 The wind guide device 10 is arranged in the cabinet 1 and adjacent to the equipment installed in reverse.
[0023] The wind guide device 10 is used to guide the cold air in the cold air channel to the air inlet on the front of the equipment installed in reverse. Specifically, the wind guide device 10 is hollow and has openings at both ends, the opening at one end of the wind guide device 10 is close to the cold air channel and covers the air inlet of the cabinet 1, so that the wind guide device 10 is in communication with the cold air channel outside the cabinet, and the opening at the other end of the wind guide device 10 is opposite to the front air inlet of the equipment installed in reverse. Since the equipment is provided with a heat dissipation fan, the air can be sucked from the front during operation, so that the cold air in the wind guide device 10 is sucked into the equipment from the air inlet of the equipment, so that the equipment can dissipate heat by using the cold air. The flow direction of the cold air is shown by the dotted line in Figure 2 .
[0024] The utility model discloses a wind -guiding device is arranged in the position of the equipment of reverse installation adjacent, and the cold wind of cold wind channel is guided to the air inlet of equipment front through the wind -guiding device, can make full use of the cold wind of cold wind channel, makes the equipment of reverse installation can utilize the cold wind and carry out effective heat dissipation, avoided the equipment failure or crash of equipment because of high temperature, ensured the normal operation of equipment, improved security greatly.
[0025] In combination with reference Figure 3 , Figure 3 For Figure 2 The utility model discloses a wind -guiding device is arranged in the position of the equipment of reverse installation adjacent, and the cold wind of cold wind channel is guided to the air inlet of equipment front through the wind -guiding device, can make full use of the cold wind of cold wind channel, makes the equipment of reverse installation can utilize the cold wind and carry out effective heat dissipation, avoided the equipment failure or crash of equipment because of high temperature, ensured the normal operation of equipment, improved security greatly.

[0027] In actual application scenarios, the height of the device can be 1U or multiple U, and therefore, by setting the second air guide part 102 with a corresponding height, the effective heat dissipation of the device with different heights can be achieved. For example, when the first air guide part 101 and the second air guide part 102 are both in the shape of a hollow square tube, the height of the device installed reversely is 1U, the height of the second air guide part 102 is set to 2U; the height of the device installed reversely is 2U, the height of the second air guide part 102 is set to 3U. In addition, in other application scenarios, for example, multiple devices installed reversely are arranged in consecutive rack units, the effective heat dissipation of the multiple devices installed reversely can also be achieved by setting the second air guide part 102 with a corresponding height. For example, three devices installed reversely are arranged in consecutive three rack units, the first air guide part 101 is arranged in the next rack unit below the lowermost device installed reversely, and then the second air guide part 102 vertically connected with the first air guide part 101 is arranged at the position close to the hot air passage in the four rack units, and the opening of the second air guide part 102 is directed to the three devices installed reversely, so that the effective heat dissipation of the three devices installed reversely can be achieved.
