A water-cooled computer mainframe case with convection-type two-way ventilation as claimed in claim 1, characterized in that: The main case (1) comprises a rectangular gusset plate (104), a rectangular filter screen (105) and an airflow input through hole (106). A rectangular gusset plate (104) is welded to both the front and rear end surfaces of the main case (1), and the rectangular gusset plate (104) corresponds to the portion of the truncated cone-shaped protrusion (102). A rectangular filter screen (105) is embedded and installed on the side end surfaces of the two rectangular gusset plates (104) facing the inside of the main case (1), and the portion of the rectangular filter screen (105) corresponds to the portion of the circular filter screen (103). The side end portions of the two rectangular gusset plates (104) facing the inside of the main case (1) are each provided with an airflow input through hole (106) connected to the inner concave end thereof.

5. A water-cooled computer mainframe case with convection-type two-way ventilation as claimed in claim 1, characterized in that: The convection heat dissipation mechanism (4) comprises a circular protrusion (403), a circular rubber sheet (406) and a circular connecting hole (408). The left and right edges of the top surface of the rectangular block (401) are each provided with a circular protrusion (403), and the axial center of the top surface of the circular protrusion (403) is each provided with a circular connecting hole (408) connected to the rectangular convection heat dissipation exchange chamber (402). A circular rubber sheet (406) having the same diameter as the circular connecting hole (408) is sealed and bonded to the inner circumference of the circular connecting hole (408) adjacent to the top opening end.

6. A water-cooled computer mainframe case with convection-type two-way ventilation as claimed in claim 5, characterized in that: The convection heat dissipation mechanism (4) comprises a cut-off opening (407) and a top block (409); a cut-off opening (407) in a cross-shaped structure is provided at the axial center of the circular rubber sheet (406); the cut-off opening (407) in a cross-shaped structure is in a sealed closed state under normal conditions; the inner circumference of the circular connecting hole (408) is provided with a total of four top blocks (409) in a ring array; the four top blocks (409) are spaced apart from the cut-off line of the cut-off opening (407); and the top surfaces of the four top blocks (409) are in contact with the bottom surface of the circular rubber sheet (406).
