Computer device, case and water-cooling heat dissipation device

The invention discloses a computer device, a case and a water-cooling heat dissipation device. The computer device comprises the case, an electronic assembly and a water-cooling assembly. A containing space is defined by the machine shell, and at least one side of the machine shell is provided with an internal flow channel, a fluid inlet and a fluid outlet, wherein the fluid inlet and the fluid outlet are communicated with the internal flow channel. The electronic component is located in the accommodating space. The water cooling assembly comprises a first water cooling head and a water cooling row. The first water cooling head is in thermal contact with the electronic component. The first water-cooling head, the water-cooling row and an internal flow channel on at least one side of the machine shell are communicated to form a circulating flow channel. The fluid inlet and the fluid outlet of the machine shell are communicated with the water cooling row and the first water cooling head respectively. 一种计算机装置、机壳
