Heat pipe for long distance

Abstract

The present invention relates to a heat pipe for long distance and, in particular, to a heat pipe constituted by an evaporating unit for evaporating working fluid to form vapor, a condensing unit spaced at a long distant from the evaporating unit and discharging heat from a transferred vapor to the outside, and a transferring unit formed as a connecting tube of a general form having a single function connecting the evaporating unit and the condensing unit to transfer only the evaporated fluid vapor, wherein a working fluid supplier is formed in the evaporating unit in order to supplement the evaporated working fluid from the outside and a condensation liquid discharging unit is formed in the condensing unit in order to discharge condensation liquid generated by condensing the vapor to the outside. Accordingly, a recovery pipe formed for a condensation liquid carrying function of a connecting tube in the prior art is removed, making it possible to perform a long distance heat supply irrespectively of a ground landscape feature on which the transferring unit may lie. Also, the pipe connecting tube of a general form having a single function is formed with a heat insulator in order to prevent heat loss during the long distance transfer, whilst making it possible to reduce fabrication and material cost. As such, the heat pipe for long distance of the present invention comprises: an evaporating unit absorbing heat from the outside to evaporate working fluid contained therein; a transferring unit transferring vapor generated from the evaporating unit; and a condensing unit discharging the heat of the vapor transferred through the transferring unit to the outside, wherein the condensation liquid generated from a heat-discharge heat exchanger in the condensing unit is not recovered through a recovery path or a separate recovery pipe.

1 . A heat pipe ( 100 ) for long distance comprising:
 an evaporating unit ( 10 ) absorbing heat from the outside to evaporate working fluid contained therein, and having a heat-absorption heat exchanger ( 11 ) formed for heat exchange;   a transferring unit ( 20 ) transferring vapor generated from the evaporating unit ( 10 ); and   a condensing unit discharging the heat of the vapor transferred through the transferring unit ( 20 ) to the outside, and having a heat-discharge heat exchanger ( 31 ) formed for heat exchange,   wherein the transferring unit ( 20 ) is formed as a connecting tube ( 21 ) having a single function connecting the evaporating unit ( 10 ) and the condensing unit ( 30 ) to transfer the vapor in order to allow the vapor to be transferred in only one direction and allow condensation liquid generated from the condensing unit not to be recovered, the evaporating unit ( 10 ) is formed with an evaporation working fluid supplier ( 12 ) in order to supplement an evaporation working fluid evaporated through the heat-absorption heat exchanger ( 11 ) from the outside, and the condensing unit ( 30 ) is formed with a condensation working fluid discharging unit ( 32 ) in order to discharge condensation working liquid formed by the heat discharged to the outside through the heat-discharge heat exchanger ( 31 ) to the outside.   
   
   
       2 . The heat pipe ( 100 ) for long distance of  claim 1 , wherein one end of the connecting tube ( 21 ) is installed with a decompression vacuum device ( 22 ) to maintain the inside of the connecting tube in a decompression vacuum state in order to maintain the transferred vapor from condensing. 
   
   
       3 . The heat pipe ( 100 ) for long distance of  claim 1 , wherein a recovery pipe ( 40 ) and a pump ( 50 ) are further installed between the evaporating unit ( 10 ) and the condensing unit ( 30 ) in order to be able to support recovering the condensation liquid generated from the condensing unit ( 30 ) to the evaporating unit ( 10 ). 
   
   
       4 . The heat pipe ( 100 ) for long distance of  claim 1 , wherein the heat pipe ( 100 ) is installed with a controller ( 60 ) electrically and automatically controlling so as to attain the best working condition of the heat pipe ( 100 ).
