Abstract

The emergence of electrical energy is closely related to the use of power. However, the temperature of electronics could be compared to those encountered by a shuttle nose when entering the atmosphere and requires a thermal management. The technology investigated in this paper is original because able to evacuate important heat flux. The proposed system is named Biphasic Fluid Loop Mechanically Pumped (BFLMP) with a transport capacity of the thermal power up to 10 MW.m, exceeding in this way the performance of all known technologies. This paper begins with a description of the test rig of the BFLMP and its instrumentation. The second part of the paper is a detailed study of the thermo hydraulic behavior of the pump-pipe system. The proposed model is based on the bond graph theory because of its energetic approach and the multi-physics character of the studied system. A validation test is launched using water with regulation temperature at the pressurizer set at 60°C, the temperature of the secondary circuit is regulated at 37°C, a power crenel of 400 W has been applied on the evaporator. Results are discussed in a last part; the model shows up good agreement with the experimental results. The volumetric pump studied in this work is original because it was specially designed and manufactured to equip the BFLMP developed in collaboration with the research laboratory CRIStAL. This pump has been patented. Also, this centrifugal machine has been tested and has been characterized. Its performance curves are obtained and used in the model proposed in this paper. In addition, the proposed algorithm models the pump using a resistive bond graph element R.
