Description

Water-cooled plate assembly

The present invention relates to a cooling assembly, in particular to a water cooling plate assembly.

Generally speaking, a computer mainly includes a casing, a power supply, a motherboard, a central processing unit, a display card, and an expansion card. The power supply and the motherboard are installed in the casing, and the central processing unit, display card and expansion card are installed on the motherboard. When the computer is running, the central processing unit is responsible for data calculation, and the display card is responsible for image calculation, both of which will generate a lot of heat. Therefore, computer manufacturers generally install fans or water-cooling radiators to dissipate heat from the central processing unit or graphics card.

Taking a water-cooled radiator as an example, a water-cooled radiator generally includes a water-cooled head, a water-cooled radiator, and a pump. The water block is in thermal contact with the CPU or graphics card. Water cooling radiators are used for heat dissipation. The water cooling head, the water cooling row and the pump are connected to form a circulation channel. Coolant is stored in the circulation channel. The pump drives the coolant to flow through the water-cooling head and the water-cooling row to form a cooling cycle. When the coolant is in the cooling cycle, the coolant will transfer the heat generated by the CPU or graphics card to the water cooling radiator, and dissipate heat through the water cooling radiator. However, the heat dissipation efficiency of the current water-cooled radiators for heat sources such as central processing units and display cards is still insufficient. Therefore, how to further improve the efficiency of water-cooled radiators The heat dissipation efficiency of the heat sink to heat sources such as the central processing unit and the graphics card has become a major design issue.

The present invention is to provide a water-cooled plate assembly, so as to improve the heat dissipation efficiency of the water-cooled plate assembly to heat sources such as a central processing unit.

A water-cooled plate assembly disclosed in an embodiment of the present invention includes a base, a cover, a water inlet joint and a water outlet joint. The cover body is installed on the base, and the cover body and the base jointly surround a liquid flow space. The cover has a water inlet and a water outlet. In the direction of the long side of the cover body, the water inlet and the water outlet are respectively located on opposite sides of the cover body. The water inlet joint is installed at the water inlet of the cover body. The water outlet connector is installed at the water outlet of the cover body.

According to the water-cooled plate assembly of the above-mentioned embodiment, by changing the water inlet and the water outlet to be respectively located on opposite sides of the cover body, the heat dissipation effect of the cooling liquid on the base is improved, thereby improving the overall heat dissipation effect of the water-cooled plate assembly.
