The invention belongs to the field of radiators, and provides an integrated phase-changing heat-sink high-power LED lamp radiator which comprises a heat dissipation fin body and an LED bead substrate. A hollow plane heat pipe cavity is formed by the heat dissipation fin body and the LED bead substrate in a sealing mode. A capillary core is arranged on the wall of plane heat pipe cavity, and mixed refrigerants are further injected in the plane heat pipe cavity. The heat dissipation fin body and the LED bead substrate are integrated in a sealing mode, the hollow plane heat pipe cavity is formed between the heat dissipation fin body and the LED bead substrate, due to the fact that the LED bead substrate is in direct contact with the mixed refrigerants, when beads work, heat is directly and quickly transmitted to the mixed refrigerants through the LED bead substrate, thermal resistance of a physical bonding face does not exist between the beads and the heat dissipation fin body, the production technology of an existing bead substrate and beads can not be changed, product cost is lowered, two-level thermal resistance is reduced, and heat conductivity of the radiator is substantially improved.
Description
technical field [0001] The invention belongs to the field of radiators, in particular to an integrated phase-change heat sink radiator for high-power LED lamps. Background technique [0002] High-power LED lamps are the development trend of semiconductor lamps. The heat dissipation problem of lamps is the bottleneck restricting its development, which will directly affect the service life, luminous efficiency and color drift of lamps. [0003] At present, phase change heat sink heat dissipation includes two technologies: one is the phase change heat sink technology inside the lamp bead chip, which focuses on solving the problem of deriving the junction temperature inside the lamp bead chip, which is only suitable for LED wick packaging or wick module packaging, and cannot It is used for the overall heat dissipation of multiple lamp beads (or modules) of high-power LED lamps. If it is used in high-power LED lamps, it will make the heat concentrated and the overall heat dissipa...
