Flexible and transformable water-cooling device

Abstract

A flexible and transformable water-cooling device includes a liquid reservoir case and a heat exchange unit. The liquid reservoir case is for a cooling liquid to pass therethrough. The liquid reservoir case has a flexible section, which can be flexed. The flexible section has a first end and a second end opposite to each other. A first region outward extends from the first end. The heat exchange unit is disposed in the first region and has multiple radiating fins in contact with the cooling liquid passing through the first region. Due to the flexibility of the flexible section of the water-cooling device, the water-cooling device can be freely flexed and transformed in accordance with an existent space in an electronic device. Therefore, the water-cooling device can be adaptively disposed in the electronic device.

         2 . The flexible and transformable water-cooling device as claimed in  claim 1 , wherein a second region extends from the second end of the flexible section, the first and second regions being bendable about the flexible section from a horizontal parallel position to a vertical overlapping position, a pump unit being disposed at the second region and having a driver, the driver being immerged in the cooling liquid for driving the cooling liquid in the liquid reservoir case to pass through the flexible section and the first and second regions. 
     
     
         3 . The flexible and transformable water-cooling device as claimed in  claim 1 , wherein the second end of the flexible section is connected with a pump case in which a pump unit is received, the first region and the pump case being bendable about the flexible section from a horizontal parallel position to a vertical overlapping position, the pump unit having a driver immerged in the cooling liquid for driving the cooling liquid in the liquid reservoir case to pass through the flexible section, the first region and the pump case. 
     
     
         4 . The flexible and transformable water-cooling device as claimed in  claim 1 , wherein the liquid reservoir case is formed with an opening in a position where the heat exchange unit is positioned, the other side of the heat exchange unit having a heat contact face for contacting a heat source. 
     
     
         5 . The flexible and transformable water-cooling device as claimed in  claim 2 , wherein the first region defines a heat exchange chamber, while the second region defines a pump chamber. 
     
     
         6 . The flexible and transformable water-cooling device as claimed in  claim 3 , wherein the first region defines a heat exchange chamber, while the pump case defines a pump chamber. 
     
     
         7 . The flexible and transformable water-cooling device as claimed in  claim 5 , wherein the flexible section has a passage in communication with the pump chamber and the heat exchange chamber. 
     
     
         8 . The flexible and transformable water-cooling device as claimed in  claim 6 , wherein the flexible section has a passage in communication with the pump chamber and the heat exchange chamber. 
     
     
         9 . The flexible and transformable water-cooling device as claimed in  claim 7 , wherein the heat exchange chamber has an outlet and the pump chamber has an inlet, the passage communicating with the outlet and the inlet. 
     
     
         10 . The flexible and transformable water-cooling device as claimed in  claim 8 , wherein the heat exchange chamber has an outlet and the pump chamber has an inlet, the passage communicating with the outlet and the inlet. 
     
     
         11 . The flexible and transformable water-cooling device as claimed in  claim 9 , wherein a mating section is disposed on the first region and a connection section is disposed on the second region, the mating section and the connection section being connectable with each other to keep the first and second regions in a folded state. 
     
     
         12 . The flexible and transformable water-cooling device as claimed in  claim 10 , wherein a mating section is disposed on the first region and a connection section is disposed on the second region, the mating section and the connection section being connectable with each other to keep the first and second regions in a folded state. 
     
     
         13 . The flexible and transformable water-cooling device as claimed in  claim 11 , wherein the mating section and the connection section are connectable with each other via a connection member.
