Abstract
A heat spreader includes a first metal cover, a second metal cover, a receiving cavity, a heat conducting block, and working fluid. The receiving cavity is formed between the first metal cover and the second metal cover, the working fluid is filled in the receiving cavity. The heat conducting block is disposed in the receiving cavity and contacted with the first metal cover and the second metal cover. The heat conducting block is corresponding to a heat source contacting area of the second metal cover. A contacting area between the heat conducting block and the second metal cover is larger than the area of the heat source contacting zone of the second metal cover.
