Abstract
A sintering-type thermotube-type soaking board with a convex platform comprises a casing and a vacuum cavity, and the casing adopts a sintered and flattened circular tube as a soaking board and is provided with a first plane and a second plane. The first plane is provided with at least one convex platform, the convex platform is a flat and smooth surface and in contact with a heating component, and an inclined surface with an inclination is formed between the convex platform and the first plane; and the second plane has a flat and level surface and is in contact with a heat-dissipation component. A capillary structure, a working fluid and at least a support body are arranged in the vacuum cavity. The design enables the soaking board to have tight contact with the heating component and the heat-dissipation component, and causes the heat of heat source to be effectively diffused; and at the same time, the soaking board can lead the working fluid on the condensing surface to timely return to the evaporating surface, thereby improving the heat-dissipation capacity.
