Abstract

The present invention relates to a flat heat spreader and a manufacturing method therefor, the heat spreader having a thin substrate in which a plurality of individual capillary tubes, filled with a predetermined quantity of a coolant, are connected to each other to form one closed loop. The heat spreader comprises: a first substrate; a second substrate tightly coupled to the first substrate; a channel provided in the form of a closed loop on at least one of the surfaces of the first substrate and the second substrate where the first and second substrates are coupled to each other; and an inlet, formed on a portion of the first substrate or the second substrate, for injecting the coolant into the channel.
