Description

container cooling system

technical field

The invention relates to a container cooling system.

Background technique

At present, as the development of data centers tends to be more flexible, the heat dissipation design methods of data centers are also becoming more and more flexible. Data centers often require a considerable amount of power to cool heat sources. A common heat dissipation method is to install an air conditioner inside the data center. If the natural low temperature can be used for cooling, energy saving can be realized.

Contents of the invention

In view of the above, it is necessary to provide a container cooling system that can effectively save energy during refrigeration.

A container cooling system, which includes a box body, a server installed in the box body, a fan and a cooling fin group, the cooling fin group includes several return chambers connected to the inside of the box body and several cold air chambers connected to the outside, Several return chambers and several cold air chambers are arranged alternately. The fan sends the hot air in the box to the return chamber for heat exchange with the cold air in the cold air chamber. After cooling, it returns to the box to dissipate heat for the server.

The box body of the container cooling system of the present invention is equipped with a cooling fin group, which includes a return cavity connected with the box body and a cold air cavity connected with the outside world. Then it flows back into the box to cool and dissipate the server, and the use of the natural environment can save electric energy and achieve the effect of energy saving and emission reduction.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

Please refer to Fig. 1 and Fig. 2, the preferred embodiment of the container cooling system of the present invention includes a control device (not shown in the figure), a box body 10 (such as a container), a number of servers 20 arranged in the box body 10, and a cooling fin group 30 And several fans 40 arranged in the casing 10 .

The box body 10 includes two side walls 11 , two end walls 12 and a refrigeration device (such as an air conditioner). Two partitions 13 parallel to the side wall 11 are mounted on the end wall 12 . A cold air passage 14 is formed between the two partitions 13 . The cold air channel 14 is used for circulation of cold air to cool the server. The server 20 is arranged under the partition and forms a hot air channel 15 between the two side walls. The hot air channel 15 is used to output the hot air generated by the server 20 . The fan 40 is installed in the cold air channel 14 and the hot air channel 15 near the cooling fin assembly 30 for sucking in cold air and discharging hot air.

Please also refer to FIG. 3 , the heat sink group 30 is formed by connecting several hollow plates in a fin-like interval. The heat sink set 30 is made of metal, and includes several return chambers 31 and several cold air chambers 32 arranged alternately with the return chambers 31 . A thin plate 33 is disposed between the return cavity 31 and the cold air cavity 32 . The cooling fin set 30 covers the two side walls 11 and the two end walls 12 to form the top wall of the box body 10 , and the return cavity 31 communicates with the box body 10 .

When the temperature of the external environment of the box 10 is low, such as in autumn and winter, there is cold air around the cold air cavity 32 of the cooling fin set 30 and makes the temperature of the thin plate 33 itself relatively low. A temperature value is preset for the container. In this embodiment, the preset temperature value is 25 degrees Celsius. The control device compares the temperature of the receiving box 10 with a preset temperature value. When the internal temperature of the box body 10 is lower than the preset temperature value, the control device reduces the cooling power of the refrigeration device or closes the refrigeration device, and at the same time, starts The fan 40 in the hot air passage 15, the fan 40 in the hot air passage 15 discharges the heat generated by the server 20 to the return chamber 31 of the cooling fin group 30, and the hot air exchanges heat with the cold air in the cold air chamber 32 through the thin plate 33, Make the hot blast in the return cavity 31 cool, after the control device senses that the hot blast is cooled to a standard temperature value, close the fan 40 in the part of the hot blast passage 15, and start the fan 40 in the cold wind passage 14 to discharge the cooled gas into the cold air channel 14 to continue cooling the server 20.

The box body 10 of the container cooling system of the present invention is equipped with a cooling fin group 30 made of metal material. The cooling fin group 30 includes a return cavity 31 connected to the box body 10 and a cold air cavity 32 connected to the outside. The box body 10 The heat inside is transferred through the return chamber 31 and the cold air in the cold air chamber 32 and then cooled, and then returns to the cabinet 10 to cool and dissipate the server 20. Using the natural environment can save electric energy and achieve energy saving and emission reduction.
