Abstract: A heat conducting part is provided. The heat conducting part includes a shell, including an inner layer and an outer layer, where a cavity is enclosed by the inner layer, and the outer layer wraps a periphery of the inner layer; a capillary structure, disposed in the cavity and abutting against the shell; and cooling liquid, located in the cavity, where the inner layer and the outer layer are made of different materials, and a material density of the outer layer is lower than a material density of the inner layer. In the heat conducting part provided in this application, a material with a relatively large density and a stable chemical property may be selected for the inner layer to ensure durability of the heat conducting part.
