A cooling module used in conjunction with a heating element includes a vapor chamber and a plurality of cooling fins. The vapor chamber is in contact with one side of the heating element. The vapor chamber is disposed with a direct conduction area and a vacuum block disposed on two sides of the direct conduction area respectively. Each vacuum block forms a chamber. The cooling fins protrude from and are vertically disposed on the direct conduction area and each vacuum block, respectively. Thereby, the effects of fast vertical heat transfer to the fin and fast horizontal heat transfer to the distal cooling fins are achieved.
