Figure 2 shows the photos of various wicks designed, manufactured and tested in high temperature water heat pipes. Copper is the traditional envelope and wick material for water heat pipes at temperatures below about 150C. Many applications require integration of the heat pipes with other heat transfer and/or mechanical structures. 24.60 , Shipping Days: manufacturer catalogs Figure 3 High temperature water heat pipe test results (click graph to enlarge), Figure 4 Titanium/water heat pipe assemblies, Figure 5 Titanium/water heat pipes integrated in a space radiator panel, 1046 New Holland Avenue, Lancaster, Pennsylvania 17601, USA | Phone: 717.295.6061 | Contact Us, Site Map | Privacy Policy | At higher temperatures where the vapor pressure of water increases rapidly, copper is not an acceptable envelope material, due to its low strength and high mass density. 18 Days, Standard Price : Standard Price : This often requires making the heat pipes into different geometries or bonding the heat pipes with other materials.

ACT has focused on the following materials that have the best chance of being compatible with water at elevated temperatures. This heat pipe operates at 275C. The life test continues until a failure (or large T) is detected. Several examples of life test heat pipes relevant to the high temperature water heat pipe technology include: These heat pipes currently (November 2006) have been on life test for over 20,000 hours. 25.73 , Standard Price : The major consequences of incompatibility are corrosion, generation of non-condensable gases, or both. Another significant technical challenge associated with the high temperature water heat pipe technology is the design and manufacture of the wicks for high performances at the elevated temperatures. The resulting corrosion products can block portions of the wick, preventing the heat pipe from operating properly. 14 Days, Standard Price : These include, clockwise, axial grooves, mesh screen, sintered metal powders, sintered metal powder grooves (fine grooves), sintered slab and sintered metal powder grooves (large grooves). 13 Days, Shipping Days: We are sorry, but we cannot respond on each feedback. Designed for cooling systems, heat exchange systems and boilers. Used in spa facilities, kitchens, boiler piping, etc. These heat pipes had axial grooves as the wick and were tested at 150C and 200C (vapor temperature) and various adverse elevations. These materials also have high yield strengths, low densities and good commercial availability: Life tests are required to verify that the heat pipe envelope and wick materials and the working fluid are compatible for the long operating life of a heat pipe. 66.74 , Shipping Days: Figure 1 shows the temperature gradients along a life test Monel/Water heat pipe. 6.91 , Standard Price : ACT maintains an extensive life test program in demonstrating the long term operations of various heat pipe materials and fluids. Smooth surface. Same day, Standard Price : Note that the wick and envelope materials should be reasonably close in composition, to avoid gas generation by electrochemical reactions. Figure 3 shows the measured performance of two high temperature water heat pipes that are 0.5 OD and 45 long. Waters surface tension drops off quickly as the temperature increases, placing increasing burdens on the capillary wick design.
