Cooling cabinet

Abstract

A cooling cabinet includes a cabinet and a heat exchange member and an air ventilation member are received therein. A first pipe group and a second pipe group are located in the heat exchange member and each of the first and second pipe groups includes multiple parallel circulation pipes. Two respective first ends of the first pipe group and the second pipe group are in communication with each other, and two respective second ends of the first and second pipe groups are respectively in communication with a refrigerant inlet and a refrigerant outlet. The refrigerant flows through the first pipe group via the refrigerant inlet and then flows through the second pipe group and exits from the refrigerant outlet. The air ventilation member is located beside the heat exchange member and ventilates the air inside and outside of the cabinet via the heat exchange member.

What is claimed is: 
     
         1 . A cooling cabinet comprising:
 a cabinet having a space adapted to accommodate electronic devices;   at least one heat exchange member located in the space and having a circulation pipe unit received therein which is heat-conductive and refrigerant flowing in the circulation pipe unit, the circulation pipe unit having a first pipe group and a second pipe group, each of the first and second pipe groups including multiple parallel circulation pipes, two respective first ends of the first pipe group and the second pipe group being in communication with each other, two respective second ends of the first pipe group and the second pipe group being respectively in communication with a refrigerant inlet and a refrigerant outlet, the refrigerant flowing through the first pipe group via the refrigerant inlet, and then flowing through the second pipe group and exiting from the refrigerant outlet; and   at least one air ventilation member located beside the at least one heat exchange member and driving air in the space out from the cabinet via the at least one heat exchange member.   
     
     
         2 . The cooling cabinet as claimed in  claim 1 , wherein the space of the cabinet has an opening which is covered by a door, the at least one heat exchange member and the at least one air ventilation member are connected to the door. 
     
     
         3 . The cooling cabinet as claimed in  claim 2 , wherein the door has multiple heat exchange members and air ventilation members. 
     
     
         4 . The cooling cabinet as claimed in  claim 1 , wherein the at least one heat exchange member and the at least one air ventilation member are fixed in a positioning case and the positioning case is located in the space. 
     
     
         5 . The cooling cabinet as claimed in  claim 4 , wherein the positioning case includes an outer case and an inner case which is connected to the outer case, each of the inner case and the outer case has slits for ventilation. 
     
     
         6 . The cooling cabinet as claimed in  claim 5 , wherein the outer case has a recessed portion and the at least one heat exchange member is received in the recessed portion, the inner case has another recessed portion and the at least one air ventilation member is received in said another recessed portion. 
     
     
         7 . The cooling cabinet as claimed in  claim 6 , wherein the at least one air ventilation member is fixed to the inner case by a connection rod. 
     
     
         8 . The cooling cabinet as claimed in  claim 1 , wherein the at least one air ventilation member is a fan. 
     
     
         9 . The cooling cabinet as claimed in  claim 2 , wherein the at least one air ventilation member and the at least one heat exchange member are fixed in a positioning case, the door has a recess which is located close to a side of the space, the positioning case is located in the recess. 
     
     
         10 . The cooling cabinet as claimed in  claim 9 , wherein the positioning case includes an outer case and an inner case which is connected to the outer case, each of the inner case and the outer case has slits for ventilation. 
     
     
         11 . The cooling cabinet as claimed in  claim 10 , wherein the outer case has a recessed portion and the at least one heat exchange member is received in the recessed portion, the inner case has another recessed portion and the at least one air ventilation member is received in said another recessed portion. 
     
     
         12 . The cooling cabinet as claimed in  claim 11 , wherein the at least one air ventilation member is fixed to the inner case by a connection rod. 
     
     
         13 . The cooling cabinet as claimed in  claim 2 , wherein the at least one air ventilation member is a fan. 
     
     
         14 . The cooling cabinet as claimed in  claim 3 , wherein the at least one air ventilation member and the at least one heat exchange member are fixed in a positioning case, the door has a recess which is located close to a side of the space, the positioning case is located in the recess. 
     
     
         15 . The cooling cabinet as claimed in  claim 14 , wherein the positioning case includes an outer case and an inner case which is connected to the outer case, each of the inner case and the outer case has slits for ventilation. 
     
     
         16 . The cooling cabinet as claimed in  claim 15 , wherein the outer case has a recessed portion and the at least one heat exchange member is received in the recessed portion, the inner case has another recessed portion and the at least one air ventilation member is received in said another recessed portion. 
     
     
         17 . The cooling cabinet as claimed in  claim 16 , wherein the at least one air ventilation member is fixed to the inner case by a connection rod. 
     
     
         18 . The cooling cabinet as claimed in  claim 3 , wherein the at least one air ventilation member is a fan.
