Abstract
A method for manufacturing a plate-type heat exchanger in which a heat medium is sealed in a hollow part of an airtight structure formed in the interior of a plate-like container, and the heat medium is moved by capillary force from a condensing part to an evaporating part in the hollow part along heat-medium-guiding grooves formed in the container's inside surface portions that face the hollow part; wherein a plastic workable metal plate of specific thermal conductivity is prepared; a carving tool is used to repeatedly carve out a surface portion of the metal plate at specific intervals along the surface portion, forming a plurality of plate-like fins; and a plurality of grooves formed between these fins is used as heat-medium-guiding grooves. A plate-type heat exchanger is obtained which comprises extremely small heat-medium-guiding grooves that have the necessary capillary force to move the heat medium from the condensing part to the evaporating part without affecting the set alignment or other such characteristics.
