Referring to fig. 1, fig. 1 shows a schematic structural diagram of a heat dissipation system in the prior art, in which cabinets are arranged in rows, and refrigeration is performed by a plurality of precision air conditioners, so that a cold air channel is formed between two rows of cabinets. In order to reduce the loss of the cold source, the cold air channel can be set to be a closed cold pool, cold air in the cold air channel enters the cabinet through the air inlet of the cabinet, equipment in the cabinet sucks the cold air, after the cold air dissipates heat of the equipment, hot air flows out of the air outlet of the cabinet, and the hot air enters the hot air channel, wherein the cold air channel can be set to be a lower air supply mode, and the cold air is sent into the closed cold pool. For some reverse installation devices, namely, the air inlets of the devices are close to the hot air channels, the direction of the air flow for heat dissipation is opposite to that of the heat dissipation air flow of the normal installation device, and in the operation process of the devices, the air inlets on the front sides of the devices can absorb hot air from the hot air channels, so that the devices cannot effectively dissipate heat to generate high temperature.

In order to solve the above-mentioned problems, in a first aspect, an embodiment of the present utility model provides an air guiding device for heat dissipation of equipment in a cabinet, as shown in fig. 2, fig. 2 shows a schematic structural diagram of an embodiment of the air guiding device for heat dissipation of equipment in a cabinet of the present utility model, where one or more pieces of equipment may be installed in the cabinet 1, each piece of equipment may occupy 1 rack unit or multiple rack units, at least one piece of equipment installed in a reverse direction is also installed in the cabinet 1, and an air inlet of the equipment installed in a reverse direction is disposed near a hot air channel, as shown in fig. 2, and the air guiding device 10 is disposed in the cabinet 1 and is disposed adjacent to the equipment installed in a reverse direction.

The air guiding device 10 is used for guiding cold air of the cold air channel to an air inlet on the front side of the equipment. Specifically, the air guiding device 10 is hollow, openings are formed in two ends of the air guiding device 10, the opening at one end of the air guiding device 10 is close to the cold air channel and covers the air inlet of the cabinet 1, so that the air guiding device 10 is communicated with the cold air channel outside the cabinet, the opening at the other end of the air guiding device 10 is opposite to the front air inlet of the device which is installed reversely, and the cooling fan is installed on the device.

According to the utility model, the air guide device is arranged at the adjacent position of the reversely installed equipment, and the cold air of the cold air channel is guided to the air inlet on the front side of the equipment through the air guide device, so that the cold air of the cold air channel can be fully utilized, the reversely installed equipment can effectively dissipate heat by utilizing the cold air, the equipment failure or downtime caused by high temperature of the equipment is avoided, the normal operation of the equipment is ensured, and the safety is greatly improved.

Referring to fig. 3 in combination, fig. 3 is a schematic perspective view of an embodiment of the air guiding device shown in fig. 2. Optionally, the air guiding device 10 includes a first air guiding portion 101 and a second air guiding portion 102, where the first air guiding portion 101 is disposed in one rack unit (i.e. 1U), and the second air guiding portion 102 is disposed near the hot air channel and is vertically connected to the first air guiding portion 101. Typically, a cabinet comprises a plurality of rack units, one rack unit having a height of 4.445cm, which can house a device of a corresponding size. In this embodiment, the first air guiding portion 101 is disposed in a rack unit, and the second air guiding portion 102 is disposed close to the hot air channel and is vertically connected with the first air guiding portion 101, so as to form a closed and communicated L-shaped structure, and since the location of the second air guiding portion 102 does not occupy the space of the rack unit used by the apparatus, only the first air guiding portion 101 occupies a rack unit in practice, and the occupied area of the air guiding device 10 is small.

Alternatively, the first air guiding portion 101 and the second air guiding portion 102 may be hollow square pipes, but may also be other shapes, such as circular pipes, which are not limited herein.

In an actual application scenario, the height of the device may be 1U or more, so that by setting the second air guiding portion 102 with a corresponding height, effective heat dissipation is achieved for devices with different heights. For example, for a duct in which the first air guide 101 and the second air guide 102 are hollow, the height of the equipment to be installed in the reverse direction is 1U, the height of the second air guide 102 is set to 2U, and the height of the equipment to be installed in the reverse direction is set to 2U, and the height of the second air guide 102 is set to 3U. In addition, in other application scenarios, for example, a plurality of devices installed in opposite directions are arranged in a continuous rack unit, and effective heat dissipation of the plurality of devices installed in opposite directions can also be achieved by arranging the second air guiding parts 102 with corresponding heights. For example, 3 reverse installed devices are arranged in the continuous 3 rack units, a first air guide part 101 is arranged in the next rack unit of the lowest reverse installed device, then a second air guide part 102 which is vertically connected with the first air guide part 101 is arranged at the position, close to the hot air channel, of the 4 rack units, and the opening of the second air guide part 102 is opposite to the 3 reverse installed devices, so that the 3 reverse installed devices can be effectively radiated. In this embodiment, the height of the second air guiding portion 102 may be flexibly set according to the height of the reversely installed device, or flexibly set according to the number and/or the height of the reversely installed devices provided in the continuous rack unit, which is not limited herein.

The air guiding device 10 further includes an air supplying device (not shown in the drawings), which is fixedly disposed inside the air guiding device 10 and used for increasing the air supply amount, and the air supplying device can be fixed inside the air guiding device 10 by self-tapping screws. In practical application, the device installed in the opposite direction may generate great heat during operation, and the air supply device may increase the air supply amount to suck away more heat. The air blowing device may be disposed in the first air guide portion 101 or the second air guide portion 102. Optionally, the air supply device is disposed in the first air guiding portion 101, so as to facilitate the supply of cold air. The air blowing device may be a device having an air blowing function such as a jet fan, and is not limited herein.

Wherein, first wind-guiding portion 101 can set up in the adjacent frame unit in the top or the below of reverse installation equipment, and preferably, first wind-guiding portion 101 sets up in the adjacent frame unit in reverse installation equipment below, helps the circulation of wind, can realize the air even circulation better, avoids local pile up the air, and the temperature is more even.

Wherein, the position of the first air guiding part 101 near the reversely installed device is provided with one or more openings, and cold air in the first air guiding part 101 can directly contact with the upper part or the lower part of the reversely installed device through the openings, which is beneficial to reducing the temperature of the reversely installed device and further dissipating heat.
