Electronic device with spray type heat dissipation device

Abstract

An electronic device includes an enclosure, a heat sink, and a spray device. The spray device includes a water box, a pump member, and a spray member. The spray member connects to the pump member. A plurality of nozzles is defined in the spray member facing the heat sink. The pump member draws water from the water box and sprays the water to the heat sink through the spray member.

         4 . The electronic device of  claim 2 , wherein the pump member further comprises a coil spring located between the cap and the press cylinder. 
     
     
         5 . The electronic device of  claim 1 , wherein the spray member comprises a buffering pipe, and the buffering pipe is substantially U-shaped. 
     
     
         6 . The electronic device of  claim 5 , wherein the pump member comprises an outlet pipe, and the outlet pipe engages with the buffering pipe by an interference fit. 
     
     
         7 . The electronic device of  claim 5 , wherein the spray member further comprises a spray pipe and a connecting pipe connecting the spray pipe and the buffering pipe, the spray pipe and the connecting pipe are substantially straight, and the spray pipe is substantially perpendicular to the connecting pipe. 
     
     
         8 . The electronic device of  claim 7 , wherein the spray pipe and the connecting pipe are located in a first plane, the buffering pipe is located in a second plane, and the first plane is substantially perpendicular to the second plane. 
     
     
         9 . The electronic device of  claim 1 , wherein an outlet is defined in the enclosure, the heat sink is located adjacent to the outlet, the heat sink comprises a fan and a plurality of fins, the plurality of fins is located between the fan and the outlet, and the plurality of nozzles is directed towards the plurality of fins. 
     
     
         10 . The electronic device of  claim 9 , wherein the spray member is located adjacent the outlet. 
     
     
         11 . A spray device located in an enclosure of an electronic device for spray water to a heat sink, the spray device comprising:
 a water box;   a pump member; and   a spray member, the spray member connecting to the pump member, a plurality of nozzles defined in the spray member and directed towards the heat sink,   wherein the pump member is configured to draw water from the water box and spray the water to the heat sink through the spray member.   
     
     
         12 . The spray device of  claim 11 , wherein the pump member comprises a press cylinder, a press pole, and a cap located on the press pole; and the pump member is configured to draw the water to the spray member by pressing down the cap. 
     
     
         13 . The spray device of  claim 12 , wherein the pump member further comprises a baffle, the baffle is located on the enclosure, a through hole is defined in the baffle, and the cap is configured to move through the through hole. 
     
     
         14 . The spray device of  claim 12 , wherein the pump member further comprises a coil spring located between the cap and the press cylinder. 
     
     
         15 . The spray device of  claim 11 , wherein the spray member comprises a buffering pipe, and the buffering pipe is substantially U-shaped. 
     
     
         16 . The spray device of  claim 15 , wherein the pump member comprises an outlet pipe, the outlet pipe engages with the buffering pipe by an interference fit. 
     
     
         17 .
