Gravity heat dissipation device

A gravity heat dissipation device, comprising:

• a fixing frame;
• a heat conduction block installed in the fixing frame to contact a heat source;
• a first heat pipe connected to the heat conduction block, wherein the first heat pipe comprises a heat absorption portion, a connection portion and a heat dissipation portion, wherein the connection portion of the first heat pipe is connected between the heat absorption portion of the first heat pipe and the heat dissipation portion of the first heat pipe, and the connection portion of the first heat pipe is located below the heat absorption portion of the first heat pipe and the heat dissipation portion of the first heat pipe;
• and
• a second heat pipe connected to the heat conduction block and the first heat pipe, wherein the second heat pipe comprises a heat absorption portion, a first connection portion and a first heat dissipation portion, wherein the first connection portion of the second heat pipe is connected between the heat absorption portion of the second heat pipe and the first heat dissipation portion of the second heat pipe, and the first connection portion of the second heat pipe is located above the heat absorption portion of the second heat pipe and the first heat dissipation portion of the second heat pipe.
