Title:
SPRING-SHAPED HEAT SINK AND RADIATOR WITH SPRING-SHAPED HEAT SINK
Document Type and Number:
WIPO Patent Application WO/2016/110053
Kind Code:
A1
Abstract:
Disclosed are a spring-shaped heat sink (10) and a radiator (1) with the spring-shaped heat sink (10). The spring-shaped heat sink (10) is formed integrally by winding a spring. The upper end of a first extension section (131) is connected to the upper end of an upper-layer spring body (110) and extends to the bottom surface of a lower-layer spring body (120). One end of a first heat conducting section (141) is connected to the lower end of the first extension section (131), and coiled on the inner side of the bottom surface of the lower-layer spring body (120) or encircled on the outer side of the bottom surface. The upper end of a second extension section (132) is connected to the lower end of the upper-layer spring body (110) and extends to the bottom surface of the lower-layer spring body (120). One end of a second heat conducting section (142) is connected to the lower end of the second extension section (132), and coiled on the inner side of the bottom surface of the lower-layer spring body (120) or encircled on the outer side of the bottom surface. The upper end of a third extension section (133) is connected to the upper end of the lower-layer spring body (120) and extends to the bottom surface of the lower-layer spring body (120). One end of a third heat conducting section (143) is connected to the lower end of the third extension section (133), and coiled on the inner side of the bottom surface of the lower-layer spring body (120) or encircled on the outer side of the bottom surface. The spring-shaped heat sink (10) has higher heat conduction efficiency and heat dissipation efficiency, good ventilation performance and greatly reduced weight, and the shape and size thereof can be set based on requirements.
