NOVELTY - The utility model claims a high-efficiency heat dissipation type computer back cover, comprising a shell, the bottom of the cavity of the shell is fixedly connected with a fan, the bottom of the shell and the two sides of the fan are provided with radiating holes. the right side in the shell cavity is fixedly connected with a condensate tank, top of the condensation liquid tank is connected with a connection pipe, the top of the connection pipe is connected with a water pump, the right side of the water pump through the connection pipe is connected with the condensing pipe; the condensing pipe far away from one end of connection pipe is connected with the condensing liquid tank. the top of the inner cavity of the shell right side is provided with a slot, the top of said shell body is opened with a long groove. This utility model through the cooperation of the shell, a fan, a radiating hole, a condensing liquid tank, a water pump, a condensing pipe, a clamping groove, a long groove, a radiating copper and graphene fins can simplify the back cover structure, but it will not heat dissipation effect and the desk surface are of little influence the distance, better guarantee the use performance of the computer.
