BACKGROUND 
     1. Technical Field 
     The exemplary disclosure generally relates to heat source recycling units, and particularly, relates to a heat source recycling unit for recycling excessive heat output by an electronic device such as computer and a heat source recycling system using the same. 
     2. Description of Related Art 
     With the development of technologies and the popularization of electronics, computers are now in widespread use, and consumers may now enjoy the full convenience of high technology electronic products such as computers almost anytime and anywhere. People often need to use computer in their daily life for work and pleasure. Electronic components assembled within the computer (such as the CPU, the main board, etc. assembled within the mainframe thereof) often output lots of heat energy during the working process. 
     However, the heat energy output by the computer are often transmitted or emitted to the outside of the mainframe of the computer by heat sinks and radiator fans, accordingly, the heat energy is not utilized and becomes waste. 
     Therefore, there is room for improvement within the art.

In the exemplary embodiment, the heat dissipation area  13  includes several heat dissipation holes  132  defined through back panel  11 . The heat sinks are attached to or mounted on the CPU to dissipate heat. The radiator fans are assembled within the computer mainframe  10  and located near the heat dissipation area  13  of the back panel  11  to expel the heat energy formed within the computer mainframe  10 . 
     Also referring to  FIG. 2 , the heat source recycling unit  30  is fixed to a waste heat source, such as the heat sinks, or the heat dissipation area  13  of the back panel  11  of the computer mainframe  10 , to obtain heat energy output by the computer mainframe  10 . The heat source recycling unit  30  includes at least one heat removing device  31 , a filter device  33  and a heat preservation box  34 . In the exemplary embodiment, the heat removing device  31  includes a superconducting duct with high-thermal conductivity. An inner wall of the superconducting duct is coated with a metal powder layer such as yttrium, barium and other heat superconducting material. The heat removing device  31  is used to transfer the heat energy to the heat preservation box  34  and includes a heat inlet end  311  and a heat outlet end  313 . The heat inlet end  311  is connected to the heat dissipation area  13  of the back panel  11  or the heat sinks assembled within the computer mainframe  10  for obtaining heat energy output by the computer mainframe  10 . 
     The filter device  33  is disposed in between the heat inlet end  311  and the heat outlet end  313  of the heat removing device  31  to filter out water vapor, smudge, dust, etc. contained in the heat source. In the exemplary embodiment, the filter device  33  is a filter screen. It is to be understood that the filter device  33  could further include a blowing device (not shown) to pump the air within the heat source recycling unit  30  to conduct the heat quickly. 
     The heat preservation box  34  is connected to the heat outlet end  313  of the heat removing device  31  to absorb the heat gathered from the computer mainframe  10 . The heat preservation box  34  includes a box body  35  and a door  36  rotatably assembled to the box body  35 . The box body  35  includes a heat source conversion device  37 , a heat preservation room  38  and a refrigeration room  39 .
