Example Embodiment

[0021] It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other if there is no conflict. The present invention will be further described below in conjunction with the drawings.

[0022] Such as figure 1 , figure 2 As shown, the heat sink of the present invention includes a first fixing plate 1, a second fixing plate 2, 8 heat-conducting solid pipes 3 made of AL6063 and 55 heat-dissipating hollow pipes 4 made of AL6063 with a wall thickness of 0.3 mm to 1 mm. Ground, the thickness of the heat dissipation hollow tube 4 is 0.4 mm. Among them, the thickness of the first fixing plate 1 is 4 mm to 10 mm, preferably a circular plate structure with a thickness of 6 mm, which is manufactured by aluminum plate metal stamping made of AL1070; the second fixing plate 2 is 0.5 mm to 2 mm thick. The thickness of the second fixing plate 2 is 1 mm, and it is also made of aluminum plate metal stamping made of AL1070; the first f

Abstract

The invention discloses a heat radiator. The heat radiator comprises a first fixing plate and a second fixing plate, and a plurality of solid heat conducting tubes and a plurality of hollow heat radiating tubes are distributed between the first fixing plate and the second fixing plate. Since the solid heat conducting tubes and the hollow heat radiating tubes are distributed between the first fixing plate and the second fixing plate, and a plurality of air convection holes are formed in the first fixing plate and the second fixing plate, air convection is formed on all surfaces of the heat radiator by the aid of a chimney effect principle, and the heat radiator is higher in effective heat radiating area proportion, larger in heat radiating area in unit volume, lower in manufacturing cost, lighter in weight, smaller in size, safer in use and stronger in market competitiveness.
