Title: Container with cooling system

Description:
BACKGROUND 
     1. Technical Field 
     The disclosure generally relates to cooling systems, particularly to a container including a cooling system which uses outside air to dissipate heat generated by computer servers in the container. 
     2. Description of Related Art 
     To quickly establish a cloud operating system, a container is typically used to act as a room for the cloud operating system. When designing a container for containing multiple computer servers, an air conditioner is installed in the container for controlling the temperature to a desirable level to cool the computer servers. 
     However, air conditioners usually consume high amounts of power. When outside temperatures become lower, for example, in winter, the container cannot use outside temperatures efficiently to cool the computer servers, wasting power. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       FIGS. 1 and 2 , show an exemplary container  10  used for housing electrical equipment, such as telecommunication components. In this exemplary embodiment, the container  10  includes a number of computer servers  20 , a number of heat dissipating fins  30 , a first group of fans  41 , and a second group of fans  42 . 
     The container  10  includes a hollow main body  11  with a top wall  12 . Two frames  13  are symmetrically mounted in the main body  11 . The computer servers  20  are arranged in the frames  13 . The frames  13  divide the main body  11  to create a middle airflow channel  14  and two side airflow channels  15 . Each computer server has conventional air vents (Not shown) that allow air to be drawn into and exit the computer server. Cold air from the middle airflow channel  14  allows cold airflow to be drawn into and pass through the computer server. Warm air is drawn into and passes through the computer server and exit through side airflow channels  15  to allow hot airflow to pass through. An air condition  200  is installed in the main body  11  for controlling the temperature to a desirable level to cool the computer servers  20 . One or more sensors  50  are mounted in the container  10  for detecting an inside temperature of the container  10 . 
     The heat dissipating fins  30  are positioned parallel to each other and positioned along the top wall  12 . Each heat dissipating fin  30  includes a hollow cavity  31 , and communicates with an inside of the main body  11 . A number of flow spaces  32  are defined between the heat dissipating fins  30 . Cold airflows passing through the flow spaces  32  can cool the hot airflow in the cavity  31 . To have a high heat dissipating effect, each heat dissipating fin  30  is made of metal. 
     The first group of fans  41  is positioned in the middle airflow channel  14 , and the second group of fans  42  is positioned in the side airflow channels  15 . The first group of fans  41  directs a cold airflow to the middle airflow channel  14  for heat dissipating heat from the computer servers  20 . The second group of fans  42  directs hot airflow through the side airflow channels  15  to the heat dissipating fins  30 . 
       FIG. 3  is a block diagram depicting the control system for controlling the container with cooling system. A control device  100  is electronically connected to the first and second group of fans  41 ,  42 , and the air conditioner  200 . The control device  100  can receive an inside temperature of the container  10  detected by one or more sensors  50 . The controller device  100  compares the detected temperature with a predetermined temperature, for example, 25° C. If the inside temperature of the container  10  is determined to be lower than the predetermined temperature, the control device  100  transmits a signal to turn off the air conditioner  200 , and activates the first, second group of fans  41 ,  42  for heat dissipating heat. 
       FIG. 2  is used for showing a state in use. When the controller device  100  causes the first group of fans  41  and the second group of fans  42  to operate, the first group of fans  41  draws cold airflow to the middle airflow channel  14  for heat dissipating heat of the computer servers  20 . The second group of fans  42  draws hot airflow in the side airflow channels  15  to the heat dissipating fins  30 . The hot airflow in the heat dissipating fins  30  are cooled by the cold air in the flow spaces  32  to be further directed to the middle airflow channel  14 . Accordingly, the container  10  uses the outside airflow to dissipate heat. 
     It is to be understood, however, that even through numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
