Patent attributes
A heat dissipation unit with axial capillary structure includes a case and at least one tubular body. The case has an internal case chamber and at least one opening in communication with the case chamber. A case capillary structure is formed in the case chamber. The tubular body has at least one axial capillary structure, an open end and a closed end. The open end and the closed end together define a tubular body chamber in communication with the open end. The axial capillary structure is disposed in the tubular body and the open end is plugged in the opening. The axial capillary structure directly abuts against and connects with the case capillary structure disposed on the bottom side of the case in the case. The heat dissipation unit with axial capillary structure is able to achieve better capillary transfer effect.
