LED light sources are evenly distributed on the PCB circuit board. Two guard plates are symmetrically set at the bottom of noumenon. The guard plate has through-hole. The through-holes of two guard plates face each other. Cooling water pipe is set between the two through-holes. Flexible pipe fits at both ends of cooling water pipe. The flexible pipe has pipe joint. Helical heat conduction pipe is set at the bottom of noumenon. The heat conduction pipe leans against the PCB circuit board. Solar photovoltaic panel is set at the edge of top of noumenon. Accumulator and inverter are set at the bottom of noumenon near both sides of guard plates. The solar photovoltaic panel, inverter and accumulator are electrically connected in proper order. The structure of this device is simple, and its cost is low. Besides, it is powered by solar energy, so it is energy-saving and environmentally friendly. Hence, it is suitable for promotion..... ----6 ---------7~ _ __ _ 2 40 14
