Air-cooling system for metal oxide semiconductor controlled thyristors employing miniature heat pipes

Autor: B. Donovan, Yiding Cao, J. E. Beam

Publikováno v: Journal of Thermophysics and Heat Transfer. 10:484-489

Different cooling methods for metal oxide simeiconductor controlled thyristors (MCTs) are discussed, and an air-cooling system employing miniature heat pipes as thermal spreaders is proposed. Theoretical analyses show that the proposed air-cooling sy

Publikováno v: Journal of Propulsion and Power. 12:398-404

A metal oxide semiconductor controlled thyristor (MCT) is a solid-state high-current switching device. Because of its high-current and high-heat dissipation, this device requires an advanced cooling arrangement. A sample MCT device was successfully t

Thermal conductivity enhancement for phase change storage media

Autor: Louis C. Chow, J. E. Beam, J. K. Zhong

Publikováno v: International Communications in Heat and Mass Transfer. 23:91-100

Thermal energy storage can be used as either a heat source or heat sink for spacecraft energy conversion and heat rejection systems. One major issue that needed to be addressed is that most phase-change materials (PCMs) with high energy storage densi

Capillary flow properties of mesh wicks

Autor: J. H. Ambrose, Louis C. Chow, J. E. Beam

Publikováno v: Journal of Thermophysics and Heat Transfer. 4:318-324

Prediction of heat pipe behavior is extremely important in the design of thermal control for all types of spacecraft. Heat pipes are an important element in spacecraft thermal control. Heat pipes may be subjected to pulsed- heat loading or rapid tran

Experiments and analyses of flat miniature heat pipes

Autor: Yiding Cao, B. Donovan, J. E. Beam, M. Gao

Publikováno v: IECEC 96. Proceedings of the 31st Intersociety Energy Conversion Engineering Conference.

Two flat copper-water axially grooved miniature heat pipes are fabricated employing the electric-discharge-machining (EDM) wire-cutting method. Because of the advantage of the EDM method, axial grooves are provided around the entire interior perimete

Influence of external thermal resistances on forced convective cooling of power devices

Autor: J. E. Leland, G. Fronista, R. Ponnappan, J. E. Beam

Publikováno v: 34th Aerospace Sciences Meeting and Exhibit.

Advanced designs of electric motor controls and inverters require high-current and highfrequency switching devices such as MCTs and IGBTs. These tiny devices with only 2-4 cm footprint area for mounting, generate waste-heat fluxes up to 100 W/cm whil
