Abstract

This invention discloses a novel floodlight heat dissipation kit and floodlight, belonging to the field of floodlight technology. It solves the problems of existing static heat dissipation structures being unable to adapt to dynamic thermal field changes, and single phase change heat dissipation structures having problems such as drying out and response lag, as well as the lack of linkage and coordination between active cooling and passive phase change. It includes an adjustable micro-groove phase change mechanism and an auxiliary cooling mechanism. The adjustable micro-groove phase change mechanism includes an adjustable heat absorption plate and a micro-groove heat sink. In this invention, through the closed-loop coordination between the adjustable micro-groove phase change mechanism, the auxiliary cooling mechanism, and the linkage adjustment mechanism, the static limitations of traditional heat dissipation are broken: the cooling drive unit synchronously drives the adjustable heat absorption plate to rotate and the cooling electrode assembly to rotate according to the thermal field distribution, so that the micro-groove heat sink is always locked to the center of the heat source. At the same time, the cooling electrode assembly actively turbulents and cools the waste heat of the micro-groove heat sink, realizing dynamic matching of the heat dissipation focus and efficient coupling of active cooling.
