Аннотация: This paper presents results that demonstrate the proof-of-feasibility of multiple evaporator Loop Heat Pipes (LHP). It was demonstrated that a multiple evaporator LHP can successfully operate as a thermal control system component. A breadboard LHP with multiple evaporators (two) that retained the reliable self starting behavior of the single thermal interface LHP was developed. Program efforts were concentrated on a two pump system and investigated the performance of the dual evaporator LHP. Analytical predictons and experimental test data are compared, and important issues are discussed that will be a baseline for continued development of multiple thermal interface LHPs. All of the conclusions are based on test results, analytic modeling and the correlation of the two. Although a mathematical model that predicts the multiple evaporator LHP behavior was developed, the primary focus of the program was the development, fabrication, and test of a breadboard multi-evaporator LHP. The program clearly demonstrated that multi-evaporator LHPs are feasible and merit further development as a viable thermal control components

Ключевые слова (''Своб.индексиров.''): loop heat pipes --alyona--experimental system
Аннотация: Results of the most durable Russian on-orbit experiment with the Loop Heat Pipe are analyzed in present paper. All telemetry data on temperature measurements obtained from the experimental system ALYONA during its performance period from 1989 till 1996 are compared. Estimation of the LHP operation ability during the whole period mentioned above and determination of the calculated value of transferred heat power were executed with taking into account the boundary conditions characterizing the operation mode of the experimental system ALYONA. Some results of on-ground testing, real characteristics of radiating surfaces coating and, also, the scientific spacecraft GRANAT orientation data were taken into account for analyzing. Necessary information on the Loop Heat Pipe design, used materials, preliminary on-ground testing is presented. Besides this, the information that allows to make a conclusion on the successful Loop Heat Pipe re-starting modes occurring when the spacecraft comes into the shade zone and to judge on the LHP life time is also presented. Documents provided by different LAVOCHKIN ASSOCIATION sen ices and divisions controlling the communication data obtained from the spacecraft were used for this paper preparation

Ключевые слова (''Своб.индексиров.''): loop heat pipes --heat-transport --thermocapillary phenomena
Аннотация: Loop heat pipes (LHPs) posses a great variety of valuable properties, which make them quite promising for application both on the Earth and in space. Among these are the LHP high heat-transport capacity at an any orientation in the field of mass forces, good mass-and-size parameters and the possibility of an arbitrary configuration of transport lines. At the same time such a drawback of LHPs of the conventional type as the instability of start up and operation in the region of low heat loads reduces their performance. The problem is connected, in a general case, with the unfavourable distribution of the vapor and the liquid phases of the working fluid in the evaporator. There is reason to believe that the LHP operation can also be significantly affected by zero-g conditions, in which the distribution of a working fluid is pre-determined only by the action of surface forces and the thermocapillary phenomena. The paper performs a general analysis of the necessary conditions imposed on the construction of LHP and some designs that contribute to the retention of serviceability in zero-g conditions at low heat loads. It gives the results of laboratory investigations of an adapted ammonia LHP with a heat-transfer capacity up to 2 kWxm

Ключевые слова (''Своб.индексиров.''): miniature loop heat pipe--cpu--thermal resistance
Аннотация: The paper is devoted to the development of miniature loop heat pipes (mLHPs) with a nominal capacity of 25-30 W and a heat-transfer distance up to 250 mm intended for cooling electronics components and CPU of mobile PC. It gives the results of investigating several prototypes of mLHPs incorporated into remote heat exchanger (RHE) systems in different conditions. It has been established that in the nominal range of heat loads orientation does not practically affect the mLHPs operating characteristics. Under air cooling the total thermal resistance of such a system is 1.7-4.0degreesC/W and depends strongly on the cooling conditions and the radiator efficiency. In this case the mLHP's own thermal resistance is in the limits from 0.3 to 1.2degreesC/W, and the maximum capacity reaches 80-120 BT. The obtained results make it possible to regard mLHPs as quite promising devices for RHE systems providing thermal regimes for electronics components and personal computers.

Ключевые слова (''Своб.индексиров.''): loop heat pipes --thermal power loads--vapor flow losses
Аннотация: Loop Heat Pipes (LHPs) can transport very large thermal power loads, over long distances, through flexible, small diameter tubes and against high gravitational heads. While recent LHPs have transported as much as 1500 W, the peak heat flux through a LHP's evaporator has been limited to about 0.07 MW/m(2). This limitation is due to the arrangement of vapor passages next to the heat load which is one of the conditions necessary to ensure self priming of the device. This paper describes work aimed at raising this limit by threefold to tenfold. Two approaches were pursued. One optimized the vapor passage geometry for the high heat flux conditions. The geometry improved the heat flow into the wick and working fluid. This approach also employed a finer pored wick to support higher vapor flow losses. The second approach used a bidisperse wick material within the circumferential vapor passages. The bidisperse material increased the thermal conductivity and the evaporative surface area in the region of highest heat flux, while providing a flow path for the vapor. Proof-of-concept devices were fabricated and tested for each approach. Both devices operated as designed and both demonstrated operation at a heat flux of 0.70 MW/m(2). This performance exceeded the known state of the art by a factor of more than six for both conventional heat pipes and for loop heat pipes using ammonia. In addition, the bidisperse-wick device demonstrated boiling heat transfer coefficients up to 100,000 W/m(2) K, and the fine pored device demonstrated an orientation independence with its performance essentially unaffected by whether its evaporator was positioned above, below or level with the condenser
