Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection range of the present utility model is not limited to the following stated:
Embodiment one:
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of corrugation radiator, it comprises heat-radiating substrate 1 and radiating fin 2, this heat-radiating substrate 1 has the heat-absorbent surface 11 and radiating surface 12 that are positioned at relative both sides, described radiating fin 2 is one-body molded to be arranged on this radiating surface 12, described radiating fin 2 is ripple fin, and the height of this radiating fin 2 is 100 ~ 140mm, and the width of radiating fin 2 can be arbitrary value, when the length of radiating fin 2, when width is identical, the area of dissipation of the radiating fin 2 of this enforcement is larger than the area of common radiating fin 2, and area of dissipation at least increases by 20%, thus improve heat dispersion, the thickness of described heat-radiating substrate 1 is 10 ~ 30mm, by changing the thickness of heat-radiating substrate 1, make it thinning, thus improve heat transfer performance, further add heat dispersion, described heat-radiating substrate 1 also offers screwed hole 3, for larger-size radiator, also stud is provided with in its screwed hole 3, the relative both sides of described stud have a screw cap end and the end of thread, a spring is worn between described screw cap end and radiating surface 12, after stud is connected with thermal objects, heat-radiating substrate 1 contacts with thermal objects under the action of the spring all the time, thus ensure that the sustained delivery of heat energy, diagram does not draw stud and spring.
In the present embodiment, described heat-absorbent surface 11 offers multiple groove 4, heat pipe 5 is inlaid with in groove 4, described groove 4 is at least three, and described groove 4 is located at side by side on this radiating surface 12 and the ripple direction of groove and described radiating fin 2 is perpendicular, thus make on heat pipe 5 can the multiple radiating fin of uniform arrangement, therefore heat pipe 5 can fast by the thermal energy transfer of thermal objects on radiating fin 2, solve the problem that heat-absorbent surface heat absorption efficiency is not high, and then dispelled the heat by the large area of radiating fin 2, heat energy is dispersed in air, therefore there is splendid radiating effect.
Embodiment two:
The present embodiment is identical with embodiment one general structure, difference is that structure of heat dissipation substrate is different, in the present embodiment, described heat-radiating substrate 1 is copper-aluminum composite board, and copper coin is positioned at lower floor, aluminium sheet is positioned at upper strata, heat-absorbent surface 11 is positioned on copper coin, radiating surface 12 is positioned on aluminium sheet, described heat-absorbent surface 11 is a plane, its surface roughness is less than 1.2, flatness is less than 0.1/100mm, in the present embodiment, heat-absorbent surface 11 is arranged on copper coin, by the high thermal conductivity of copper coin, the heat energy come out of pyrotoxin is siphoned away fast, and then be delivered on radiating fin by aluminium sheet, and then dispelled the heat by the large area of radiating fin 2, heat energy is dispersed in air, thus carry the heat dispersion of corrugation radiator.
