Preparation Method for Hollow Radiator and Hollow Radiator

Abstract

The present invention discloses a preparation method for a hollow radiator and a hollow radiator. The preparation method comprises the following steps: 1) providing a feed and an insert raw material; 2) molding the insert raw material into an insert; 3) placing the insert in a cavity of a mold, and filling the cavity with the feed by injection molding in such a manner that the insert is surrounded by the feed, thereby obtaining a green body with the insert; 4) performing debinding treatment on the green body with the insert to remove the insert, thereby obtaining the green body of a hollow structure; and 5) sintering the green body to obtain the hollow radiator. By the preparation method for a hollow radiator according to the present invention, a radiator of a complex hollow structure can be fabricated, and the heat dissipation effect of the radiator can be improved. Moreover, the airtightness and leakproofness of the radiator can be guaranteed for a long time.
