Claims (1)

[Claims for Utility Model Registration] (1) A heat absorbing plate and a bottom plate are disposed in parallel, and the peripheral edges of the heat absorbing plate and the bottom plate are sealed to form a flat container, and the inside of the container is A liquid channel extending in the circumferential direction is formed by the partition wall, a vapor channel extending in a direction parallel to the center line of the container is provided inside the liquid channel, and a steam channel is provided in the space between the liquid channel and the vapor channel. Insert a required number of wicking materials having a shape such that they can come into contact with the heat absorption plate and the bottom plate, and fixing wicking materials having a required thickness to the bottom plate so that they can come into contact with the ridge-shaped wicking materials to form a permeation part. A plurality of grooves of a desired shape are provided on the lower surface of the heat absorption plate forming the top of the vaporization section, the liquid flow path and the permeation section are communicated, and the vapor flow path and the vaporization section are connected. A two-phase flow heat absorber characterized by being in communication with each other. (2) In the two-phase flow heat absorber according to claim 1, instead of providing a plurality of grooves of a desired shape on the lower surface of the heat absorbing plate forming the top of the vaporizing section, a wick having a required thickness is provided on the lower surface of the heat absorbing plate. A two-phase flow heat absorber characterized in that the top of the wick material is fixed to the wick material and the top of the wick material is brought into contact with the bottom surface of the wick material.
