Heat control device and method of manufacturing the same

A method of manufacturing a heat control device having an envelope used as a path of a working fluid that absorbs/dissipates heat by a latent heat transfer and a groove formed in an inner wall of the envelope and generating a capillary force moving the working fluid, the method comprising:

• providing an integrated single template including a protruding portion having a shape corresponding to the groove;
• forming a deposition film by depositing metal on the integrated single template;
• stacking an integrated single metal plate surrounding the deposition film;
• and
• burning out the integrated single template from the integrated single metal plate.

A method of manufacturing a heat control device having an envelope used as a path of a working fluid that absorbs/dissipates heat by a latent heat transfer and a groove formed in an inner wall of the envelope and generating a capillary force moving the working fluid, the method comprising:

• providing a pair of reinforcement templates, each having a reinforcement film at one side and a groove formed at the other side;
• pairing the reinforcement templates to contact each other;
• and
• forming the envelope by stacking an integrated single metal plate on a pair of the reinforcement templates.

A heat control device comprising:

• an envelope used as a path of a working fluid that absorbs/dissipates heat by a latent heat transfer;
• and
• a groove formed in an inner wall of the envelope and generating a capillary force moving the working fluid,
• wherein the groove or a protruding portion having a shape corresponding to the groove is formed on a template formed of a polymer, a metal deposition film is deposited on the template, metal forming the envelope is stacked on the deposition film and the template is burned out, thus forming the envelope.
