Title:
HEAT DISSIPATION DEVICE OF ULTRA-HIGH-POWER LED SPOTLIGHT
Document Type and Number:
WIPO Patent Application WO/2023/240724
Kind Code:
A1
Abstract:
A heat dissipation device of an ultra-high-power LED spotlight, comprising a first heat collection substrate (10), a second heat collection substrate (20), two first heat pipe assemblies (30), and a second heat pipe assembly (40). Hollow interiors formed by the two first heat pipe assemblies (30) and the second heat pipe assembly (40) are separately provided with a heat dissipation fin assembly (50) in the same heat dissipation direction, an evaporation section of each first heat pipe assembly (30) is connected to the first heat collection substrate (10), a condensation section of each first heat pipe assembly (30) and an evaporation section of the second heat pipe assembly (40) are separately connected to the second heat collection substrate (20), and heat generated by the LED spotlight is quickly transferred into air by means of the first heat pipe assemblies (30), the second heat pipe assembly (40) and the heat dissipation fin assemblies (50).
