The outdoor air inlet 11, the outdoor air outlet 12 and the working air inlet 13 are respectively positioned on different sides of the machine body 10, so that on one hand, the equipment installation operation is convenient, and on the other hand, the mutual mixing of external air can be prevented, and the heat dissipation effect on the dry cooler 21, the heat exchange core 31 and the condenser 32 is influenced.

Based on the same inventive concept, the utility model also provides a container data center refrigerating method which is applied to the container data center, wherein a liquid cooling system and an air cooling system are arranged in the container data center; the method comprises the following steps:

starting a liquid cooling system and acquiring outdoor temperature;

judging the magnitudes of the outdoor temperature and the first, second and third temperatures, wherein the first temperature is smaller than the second temperature;

if the outdoor temperature is lower than the first temperature, turning off the fluorine pump 36 and the compressor 35 in the air cooling system;

if the outdoor temperature is higher than the first temperature and lower than the second temperature, turning on the fluorine pump 36 and turning off the compressor 35;

In practical application, the liquid cooling system can be started all the time, so that the main heat source of the equipment unit 51 to be cooled can be cooled. For the air cooling system, because the outdoor temperature in each season is different, for example, the temperature in winter is the lowest, the temperature in spring and autumn is the highest, and in order to better utilize outdoor temperature resources and reduce electric quantity consumption, the outdoor temperature can be detected, and the functions of the air cooling system can be selectively started according to the outdoor temperature. For example, the first temperature may be preset to be 0 °, the second temperature is preset to be 15 °, the third temperature is preset to be 30 °, the detected outdoor temperature is compared, and when the outdoor temperature is lower than the first temperature, the air cooling system only exchanges heat through the heat exchange core, the compressor or the fluorine pump system does not work, and the air cooling system is directly sent into the machine room for refrigeration. The outdoor temperature is higher than the first temperature and lower than the second temperature, at the moment, the fluorine pump is started, and return air is cooled once with the heat exchange core body and then is sent into the machine room after being cooled by the evaporator. Along with the continuous rising of fresh air temperature, namely outdoor temperature is higher than second temperature, the fluorine pump can not meet the refrigeration requirement, at the moment, the compressor is started, and return air is cooled once by the heat exchange core body and then is sent into a machine room after being refrigerated by the evaporator.

Further, the equipment unit to be cooled is installed in the box body through the overhead seat, so that the liquid return pipes are arranged in the overhead seat, the pipeline is prevented from being exposed, the daily maintenance operation of workers is influenced, and the attractiveness of the container data center is guaranteed.

Further, the air cooling system integrates the heat exchange core body and the fluorine pump refrigeration cycle, and the corresponding heat exchange mode can be adjusted according to the external air temperature change, so that the heat exchange can be controlled to the greatest extent, the electric quantity is saved, and the heat dissipation effect of the equipment unit to be cooled can be guaranteed.
