Electronic device and liquid cooling apparatus for electronic device

An electronic device, wherein the electronic device comprises:

• at least one arithmetic unit layer, wherein each arithmetic unit layer comprises one arithmetic unit or a plurality of arithmetic units arranged side by side, each arithmetic unit comprises a first housing in a shape of a cuboid, a first side direction of the first housing extends along a first direction, a second side direction thereof extends along a second direction perpendicular to the first direction, a third side direction thereof extends along a third direction perpendicular to both the first direction and the second direction, and two ends of the first housing in the first side direction thereof are provided with a first opening and a second opening to form a coolant path extending along the first direction, wherein the arithmetic unit can be inserted and removed relative to the first housing along the first side direction of the first housing through the first opening;
• and
• a power supply, wherein the power supply is stacked with the at least one arithmetic unit layer along the second direction or the third direction, and a first side direction of the power supply is aligned with the first side direction of each arithmetic unit, and two ends of the power supply in the first side direction thereof are provided with a third opening and a fourth opening to form a coolant path extending along the first side direction thereof, wherein an opening direction of the first opening corresponds to an opening direction of the third opening;
• the arithmetic unit comprises:
• the first housing;
• one arithmetic module or a plurality of arithmetic modules stacked along the second direction, wherein the arithmetic module is mounted in the first housing along the first direction, the arithmetic module is inserted into the first housing from the first opening, and one side of the arithmetic module facing the first opening further comprises a connection piece;
• and
• radiators provided in pairs, wherein one pair of radiators are respectively attached to the upper and lower surfaces of one corresponding arithmetic module to absorb heat of the arithmetic module, a coolant path of the radiator extends along the first direction, and inner walls of the upper and lower surfaces of the first housing are attached to the radiator;
• the arithmetic unit layer further comprises:
• a first fixed plate, wherein the first fixed plate is connected to the arithmetic unit from a side of the first opening;
• and
• a second fixed plate, wherein the second fixed plate is connected to the arithmetic unit from a side of the second opening, and the second fixed plate further comprises a plurality of first restrictor holes for a coolant to flow through;
• the power supply further comprises:
• a power supply panel, wherein the power supply panel is connected to the power supply from a side of the third opening;
• a connection terminal, wherein the connection terminal is electrically connected to the power supply and exposed to the power supply panel;
• and
• a restrictor plate, wherein the restrictor plate is connected to the power supply from a side of the fourth opening, and the restrictor plate further comprises a plurality of second restrictor holes for the coolant to flow through;
• and
• the arithmetic unit is electrically connected to the power supply through a connection between the connection piece and the connection terminal.
