Computer case with efficient heat dissipation function

The utility model discloses a computer case with efficient heat dissipation function, which comprises a computer case body, the bottom of the inner cavity of the computer case body is fixedly connected with a second partition plate, and the inner cavity of the computer case body is fixedly connected with a first partition plate above the second partition plate. After cooling liquid in the inner cavity of the cooling water tank is sucked through the input end of the first water pump, the cooling liquid is fed into the cooling water channel through the output end of the first water pump, the cooling water channel cools the inner wall of the computer case body, and then the cooling liquid in the inner cavity of the cooling water channel is sucked through the input end of the second water pump. And the output end of the second water pump sends the cooling liquid back into the inner cavity of the cooling water tank, meanwhile, the cooling liquid is cooled again through the first semiconductor chilling plate and th
