As shown in fig. 4, the outdoor heat exchangers 200 are in communication with the refrigeration units 1 of the plurality of closed cabinets 100 in a one-to-one correspondence, so that each closed cabinet 100 forms a small refrigeration system, and the refrigeration of the closed cabinets 100 is independent from each other and is not affected by other closed cabinets 100. This application has realized the inside refrigeration of closed rack 100 through setting up refrigeration unit 1 in closed rack 100 inside, can directly refrigerate closed rack 100, compares the diffuse formula refrigeration mode among the prior art, has reduced external environment and envelope to the influence of refrigeration effect, has improved refrigeration efficiency to reduce the consumption of the energy, each refrigeration mutually independent between closed rack 100 in addition can not influence each other.
As shown in fig. 3, the refrigeration unit 1 includes an air duct 11 formed by a housing, the air duct 11 has an air inlet 14 and an air outlet 15, the air inlet 14 and the air outlet 15 can be communicated with the cabinet 5, a heat exchange tube 12 and a fan 13 are disposed in the air duct 11, and the fan 13 can make air enter through the air inlet 14, then exchange heat with the heat exchange tube 12, and blow out through the air outlet 15.
As shown in fig. 3, the refrigeration unit 1 includes an air duct 11 formed by a housing, and the air duct 11 has an air inlet 14 and an air outlet 15 communicated with the cabinet 5, so that air in the cabinet 5 can be introduced into the air duct 11 through the air inlet 14 and the air outlet 15. The heat exchanger 12 is arranged in the air duct 11, and after the air enters the air duct 11, the air can exchange heat with the heat exchanger 12, so that the effect of cooling the air is achieved. Still be provided with fan 13, fan 13 can make the better entering wind channel 11 of air in, and the air after 11 coolings in wind channel also can blow off wind channel 11 from air outlet 15 through fan 13, refrigerates the cabinet body 5, and fan 13 has accelerated the flow speed of the interior air of the cabinet body 5, the further refrigeration efficiency that improves.
In some possible embodiments, as shown in fig. 3, the refrigeration unit 1 further includes a filter layer 16 disposed in the air duct 11, and as shown in the figure, the filter layer 16 is located behind the heat exchange tubes 12 in the air flow direction in the air duct 11.
In order to filter and remove dust from air, a filter layer 16 may be disposed in the air duct 11, because the air entering the air duct 11 is to be filtered and removed dust, the filter layer 16 is disposed at a position close to the air inlet 14, the air entering the air duct 11 is firstly filtered by the filter layer 16, and then is subjected to heat exchange and refrigeration by the heat exchange tube 12, that is, the filter layer 16 is located behind the heat exchange tube 12 along the air flowing direction in the air duct 11.
Further, the fan 13 is located in front of the heat exchange pipe 12 along the air flowing direction in the air duct 11.
Because the fan 13 functions to promote the air flow, in order to maximize the effect of the fan 13, the fan 13 is disposed near the air outlet 15, so that the air flow can be accelerated, and the cooling rate can be increased.
Further, as shown in fig. 3, the number of the heat exchange tubes 12 is plural.
It should be noted that the number of the heat exchange pipes 12 can be set according to actual needs, and the operation is stopped in consideration of possible abnormal situations of the heat exchange pipes 12. At this time, if there is only one heat exchange pipe 12, the entire refrigerating unit 1 cannot be normally operated. Therefore, it is preferable that a plurality of heat exchange tubes 12 be provided so that, when one of the heat exchange tubes 12 fails to operate normally, the other heat exchange tubes 12 can operate normally, thereby ensuring the normal operation of the refrigeration unit 1.

When a failure occurs in one of the operating heat exchange tubes 12, one of the remaining non-operating heat exchange tubes 12 starts operating to exchange heat. Here, two heat exchangers 12 may be optionally provided in order to save space.
Further, a plurality of fans 13 may be provided in the refrigeration unit 1.
Because fan 13 can send the air after the cooling to the internal refrigeration of cabinet 5 through air outlet 15, set up the flow velocity that a plurality of fans 13 can further accelerate the air, also can be when certain fan 13 breaks down simultaneously, all the other fans 13 also can guarantee that the air has a faster flow velocity.
It should be noted that the fan 13 may be a variable frequency fan, and as an example, an EC fan may be selected, so that the fan 13 may be subjected to variable frequency adjustment according to actual conditions, and a suitable frequency may be selected as required, thereby saving energy of the fan.

In some possible embodiments, as shown in fig. 1 and 2, the refrigeration unit 1 is located at the top of the cabinet. When the temperature of the air in the cabinet 5 rises due to the fact that the air becomes hot, the hot air flows upwards and enters the air duct 11 through the air inlet 14 of the refrigeration unit 1 to exchange heat with the heat exchanger 12 in the air duct 11 when reaching the top of the cabinet. The cold air after heat exchange is blown out from the air outlet 15 through the fan 13, and the cold air flows downwards to refrigerate the cabinet body 5 due to the sinking of the cold air, so that the temperature in the cabinet body 5 is kept normal. By means of the principle that hot air rises, the refrigerating unit 1 is arranged at the top of the cabinet, so that the hot air can be better refrigerated, and compared with the refrigerating unit arranged at other positions and arranged at the top, the heat exchanger 12 can exchange heat with more hot air.
