Abstract

PURPOSE: To enhance heat transmission efficiency by providing needle form protrusion on the surface of heat transmission base plate which makes liquid film thin.
CONSTITUTION: Needle form protrusion 2 is established on the surface of heat transmission base plate 1. Liquid film 4 is formed when high temp. vapor contacts the heat transmission surface 3 having the above mentioned protrusion 2. At this time, thickness of liquid film 4 is made thinner in the vicinity of the tip 5 of the needle protrusion, making heat transmission rate α larger. At the heat transmission surface 3 where its protrusion 2 points downward, droplet 6 of liquid is generated at the protrusion tip when high temp. vapor condenses, and drops down. This means that excess amount of liquid is removed from the surface 3, making liquid film 4 thinner in thickness and heat transmission rate α is enhanced.
