Heat-exchange environment-friendly laptop heat dissipation device

The utility model provides a heat dissipation device in the field of auxiliary fitting of laptops, specifically to a heat-exchange environment-friendly laptop heat dissipation device, comprising a seat and a seat back connected with one side of the seat. The heat-exchange environment-friendly laptop heat dissipation device is characterized in that a first circulation temperature-reducing pipeline (A) is disposed between the surface of the seat and the seat back. The first circulation temperature-reducing system (A) is formed by a heat-absorbing pipeline on the surface of the seat and an evaporation transmission temperature-reducing system on the seat back; and a second circulation temperature-reducing system (B) is formed by a circulation heat dissipation system comprising an inner tube (B') permeating and capillary cotton fabric (D) lifting system and a gravity infiltration bell mouth (B'') system.
