Liquid-cooling device having liquid-gas isolation mechanism

A liquid-gas isolation device for separating a gas from a cooling liquid, comprising:

• a tank having an outer wall defining a storage space for accommodating the cooling liquid;
• a first conduit in fluid communication with the storage space and configured to guide a flow of the cooling liquid into the storage space;
• a second conduit in fluid communication with the storage space and configured to guide a flow of the cooling liquid out of the storage space;
• at least one baffle disposed in the liquid storage space and configured to allow a guidance of a flow of the cooling liquid in the storage space;
• and
• a plurality of flow holes defined by the baffle and the outer wall, wherein the first conduit, at least one of the flow holes, and the second conduit are configured to provide a flow path for the cooling liquid,
• and wherein the flow path extends distal to the first conduit and the second conduit to effect the separation of the gas from the cooling liquid when the cooling liquid flows via the flow path.
