The invention discloses a three-dimensional vertical heat sink and a manufacturing method thereof. The three-dimensional vertical heat sink comprises a heat conducting wire body, wherein the heat conducting wire body is a single heat conducting wire and comprises a spring body unit and a support body unit; the spring body unit is of a single heat conducting wire spiral rectangular winding body structure; the support body unit is a heat conducting wire which is diagonally connected relative to the spring body unit; the spring body unit and the support body unit are arrayed in a staggered manner and are bent in a Z shape; and the spring body unit and the support body unit are connected end to end and to form a whole and are vertically arranged on the surface of a heat radiating unit. According to the three-dimensional vertical heat sink and the manufacturing method thereof disclosed by the invention, due to the adoption of the mode, the problems of complex manufacture, high manufacturing cot and low manufacturing efficiency in the heat conducting wire body are solved and heat radiation of needle ribs with higher density can be realized.
Description
technical field [0001] The invention relates to the technical field of heat exchange applications, in particular to a three-dimensional vertical radiator and a manufacturing method thereof. Background technique [0002] In the prior art, needle ribs have better heat dissipation than sheet ribs. The traditional manufacturing method of pin ribs is extrusion molding, which has low production efficiency and high manufacturing cost. U.S. Patent US20110185573 provides a new manufacturing method. The manufacturing method uses a rod-shaped core body to be wound and then extruded to form a spring-shaped heat dissipation unit. Since a single heat dissipation unit cannot stand independently on a heat dissipation object, a piece of heat dissipation is required. The substrate is used for the support of the spring-shaped heat dissipation unit. Multiple spring-shaped heat dissipation units are welded with the substrate to form a heat sink. When the heat sink is welded to the surface that n...
