A module for data center is presented, which is used for heat sinking of a heat source. The module for data center includes a first chamber, a second chamber, and a heat pipe. The heat source is positioned in the first chamber. The second chamber is adjacent to the first chamber. In addition, the heat pipe has an evaporation end positioned inside the first chamber and a condensation end positioned inside the second chamber. The heat pipe absorbs the heat energy in the first chamber with the evaporation end, transfers the heat energy to the condensation end, and eliminates the heat energy with the condensation end.
