Abstract

This invention discloses a water-cooled light-emitting diode heat sink, applied in light-emitting diode modular with clustering allocation, which comprises cooling plate, at least a bending channel located between the cooling plates and containing heat-carrying liquid and comprising at least a turning point , at least an intake and an outlet selectively in one side of the cooling plate and connecting with a free end or turning point of the bending channel, the light-emitting diode light-emitting modular with clustering allocation pasted on the upper surface of the cooling plate. The invention has solved the problem that the diode can effectively dissipate heat.

Description

technical field [0001] The invention relates to a light-emitting diode heat sink, in particular to a water-cooled light-emitting diode heat sink. Background technique [0002] As the times change, light-emitting diodes (LEDs) can not only be used as indicator lights in electronic products, but can also be used in cluster configurations to gradually replace traditional light bulbs in the field of lighting, such as traffic lights or large outdoor signage. Light-emitting diodes are more efficient light-emitting components than traditional light bulbs. Under the same brightness, they consume less power than ordinary light bulbs, and are lightweight, energy-saving, and have a long life. However, because each LED needs to be supplied with current, although LEDs have higher luminous efficiency and less power consumption, when multiple LEDs are combined in a cluster configuration, the individual LED current The generated heat energy is not easy to dissipate due to the cluster confi...
