Abstract
A liquid cooler ( ) includes a body ( ) and a cover ( ) attached on the body. The body includes a base ( ) with a first cavity ( ) accommodating liquid, a central hollow cylinder ( ) having a passage ( ) in communication with the first cavity, and a plurality of vertical tubes ( ) in communication with the first cavity. A plurality of fins ( ) extends outwardly from the hollow cylinder. The cover defines a second cavity ( ) in communication with the passage and the tubes. The liquid within the first cavity is heated by a heat-generating electronic device and moved to the second cavity through the tubes. Heated liquid which has reached the second cavity flows down through the passage along an inner surface of the hollow cylinder and returns back to the first cavity. The heated liquid is cooled by the fins conducting heat away from the hollow cylinder.
