    His first studies of heat pipes began in 1944, his first applications were in satellites with the aim of maintaining a uniform and distributed temperature throughout the structure, then he focused more on the branch of electronics. The investigations were carried out in heat pipes that are elements of great thermal conductivity, their structure is completely closed, they state; of an evaporator, an adiabatic section and a condenser section were used; various working fluids, distilled water having a range of 30 to 200 degrees centigrade, ammonia -60 to 100 degrees centigrade, sodium 600 to 1200 degrees centigrade, mercury 250 to 650 degrees centigrade, methanol 10 to 104 degrees centigrade. Round copper, aluminum and stainless-steel heat pipes were used that are designed between 0.6 x 0.6 mm in their cross section and their length can vary between 25 and 100 mm according to their use, inside they are formed without a wick or with an enveloping fine mesh wick, sintered powder metal, axial groove and among others. The operation was applied to the evaporator that leads through the wick and the tube that vaporizes the working fluid, the pressure of the vapor is driven towards the condenser where the vapor is condensed, the capillary pressure created in the wick pumps the condensed liquid towards behind this process is continuous as long as there is capillary pressure.
