Method for sealing a heat transfer device

Abstract

Disclosed is a method for sealing a heat transfer device, comprising the following steps: step 1, completely or partially cutting off an inactive section respectively at a front and/or rear portion of the heat transfer device to form a cut-off opening close to a flow guide device inside the heat transfer device; and step 2, sealing the respective cut-off opening by wrapping around the respective cut-off opening formed in step 1 with a sealing member.

1 . A method for sealing a heat transfer device, comprising:
 step  1 , completely or partially cutting off an inactive section respectively at a front and/or rear portion of the heat transfer device to form a respective cut-off opening close to a flow guide device inside the heat transfer device; and   step  2 , sealing the respective cut-off opening by wrapping around the respective cut-off opening formed in the step  1  with a sealing member.   
     
     
         2 . The method for sealing a heat transfer device according to  claim 1 , wherein the step  1  further comprises a first sub-step of forming a pressed part by flattening the inactive section respectively at the front and/or rear portion of the heat transfer device, before completely or partially cutting off the inactive section respectively at the front and rear portions of the heat transfer device, the cut-off opening is formed at the respective pressed part. 
     
     
         3 . The method for sealing a heat transfer device according to  claim 2 , wherein the pressed part formed by the first sub-step is provided with an embossed pattern. 
     
     
         4 . The method for sealing a heat transfer device according to  claim 1 , wherein the step  1  further comprises a second sub-step of forming a welded part by welding the heat transfer device respectively at the front and/or rear portion of the heat transfer device, before or after completely or partially cutting off the inactive section respectively at the front and/or rear portion of the heat transfer device in the step  1 . 
     
     
         5 . The method for sealing a heat transfer device according to  claim 4 , wherein the second sub-step is conducted after completely or partially cutting off the inactive section respectively at the front and/or rear portion of the heat transfer device in the step  1 , and in the step  1 , completely or partially cutting off the inactive section respectively at the front and/or rear portion of the heat transfer device is conducted by means of a cutter device capable of maintaining a shut state after shutting to perform a cutting-off operation until the second sub-step is complete. 
     
     
         6 . The method for sealing a heat transfer device according to  claim 4 , wherein the step  1  further comprises, before the second sub-step, a third sub-step of pre-pressing the inactive section respectively at the front and/or rear portion of the heat transfer device. 
     
     
         7 . The method for sealing a heat transfer device according to  claim 1 , wherein the sealing member is a tin sealing member formed by a tin coating treatment. 
     
     
         8 . The method for sealing a heat transfer device according to  claim 1 , wherein the sealing member is a plastic sealing member. 
     
     
         9 . The method for sealing a heat transfer device according to  claim 8 , wherein the plastic seal is formed on the heat transfer device by an injection molding process. 
     
     
         10 . The method for sealing a heat transfer device according to  claim 1 , wherein the heat transfer device is selected from the group consisting of a heat pipe, a vapor chamber and an aluminum heat plate.
