Products
Heat pipes
Heat pipes typically provide a quick mechanism to transport heat from the spacecraft electronics and instruments to its radiators. These are two phase heat transfer devices circulating a working fluid such as ammonia that evaporates and condenses to transport heat. Heat pipes provide a highly energy efficient means to transport hundreds of watts of thermal energy across several metres.
Heat pipes can be embedded within a honeycomb panel and bonded to the inner surface of the face sheets to achieve highly efficient heat removal. Surface mountable heat pipes with flanges attach to heat pipe panels to transfer heat from internal equipment to external radiator panels.
The heat pipes have been successfully supplied for various satellite programs such as GSAT-3 (Edusat), INSAT-4A, INSAT-4B, INSAT 4CR, CARTOSAT-2A, CHANDRAYAAN, EADS EUTELSAT W2M, AVANTI HYLAS, GSAT-4, OCEANSAT-2, RISAT, GSAT-5, GSAT-5/3E, GSAT-8, ASTROSAT, GSAT-12, SS LORAL, ETC.,
