Abstract

The device for degasifying a liquid passing through a system of heating chanells covered by a capillary layer, has the capillary material made of a high heat conductivity material. Between the supporting surfaces of the capillary structure there exists a flow having a higher temperature. The capillary structure can be a network of metal wires. These can be helically wound, are consist of spaced metal rings. Alternatively, the structure can be a perforated metal sheet. The capillary structure can be enclosed by a supplementary structure which is a good conductor of heat.
