Cooling device and cooling system

Abstract

[Problem] To minimize any increase in space for installation. [Solution] A cooling device 120 according to the present invention is provided with: an evaporator 127 positioned on a rear-surface door provided in a casing 121 in such a manner as to allow opening and closing; a refrigerant relay 112 provided above the casing 121 to connect with the evaporator; and a bendable flexible tube 123, one end of which being connected to the evaporator 127 and the other end of which being connected to a side of the refrigerant relay 112 that is different from the side in which the evaporator 127 is positioned. At least a part of the flexible tube 123 is positioned below the refrigerant relay 112 so as to cross the refrigerant relay 112.

1 . A cooling device, comprising:
 an evaporator that is disposed on a rear-surface door that is mounted on a casing in an openable and closable manner;   a refrigerant relay that is placed above the casing and connected to a condenser; and   a freely bendable flexible tube one end and the other end of which are connected to the evaporator and a side of the refrigerant relay different from a side of the refrigerant relay on which the evaporator is disposed, respectively, wherein   at least a portion of the flexible tube is disposed below the refrigerant relay so as to cross the refrigerant relay in a grade-separated manner.   
     
     
         2 . The cooling device according to  claim 1 , wherein the refrigerant relay is positioned at substantially a middle above the casing. 
     
     
         3 . The cooling device according to  claim 1 , wherein the flexible tube is disposed having a plurality of bend parts. 
     
     
         4 . The cooling device according to  claim 1 , wherein at least a portion of the flexible tube is formed to extend obliquely upward from a region of the flexible tube positioned below the refrigerant relay toward the refrigerant relay. 
     
     
         5 . The cooling device according to  claim 1 , wherein a side of the refrigerant relay different from a side of the refrigerant relay on which the evaporator is disposed is positioned on a front-surface side of the casing. 
     
     
         6 . The cooling device according to  claim 1 , comprising
 a plurality of the evaporators, wherein   each of the plurality of the evaporators is connected to the refrigerant relay by means of the flexible tube.
