1. A heat dissipating device for dissipating heat generated by a heat source, comprising:

  • a substantially flat first fluid container containing an amount of working fluid therein, said working fluid being capable of changing into fluid vapor when heated, said fluid vapor being capable of changing into fluid condensate when cooled, said first fluid container having a first fluid outlet and a first fluid inlet;

    a substantially flat second fluid container made of a heat conductive material and having a device contacting side adapted to be placed in contact with the heat source, said second fluid container confining first and second accommodating spaces that are in fluid communication with each other, and having a second fluid inlet for access into said first accommodating space, and a second fluid outlet for access into said second accommodating space;

    a supply pipe interconnecting said first fluid outlet of said first fluid container and said second fluid inlet of said second fluid container;

    a return pipe interconnecting said first fluid inlet of said first fluid container and said second fluid outlet of said second fluid container;

    a first check valve unit for permitting flow of said working fluid from said first fluid container into said first accommodating space of said second fluid container via said supply pipe when a fluid pressure in said first fluid container is greater than that in said second fluid container; and

    a second check valve unit for permitting fluid flow from said second accommodating space into said first fluid container via said return pipe when the fluid pressure in said first fluid container is less than that in said second fluid container.
