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

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.

    Low-noise cooling system for PC on the base of loop heat pipes / V. G. Pastukhov, Yu. F. Maydanik // Applied Thermal Engineering. - 2007. - Vol.27, №5-6. - С. 894-901

COMPUTER COOLING -- LOOP HEAT PIPE -- PASSIVE CPU COOLING SYSTEM
Аннотация: The problem of current importance connected with a wide use of personal computers (PC) and a rapid growth of their performance is a decrease in the noise level created at the operation of cooling system fans. One of the possible ways of solving this problem may be the creation of passive or semi-passive systems on the base of loop heat pipes (LHPs) in which the heat sink is an external radiator cooled by natural and/or forced air convection. The paper presents the results of development and tests of several variants of such systems, which are capable of sustaining an operating temperature of 72–78 °C on the heat source thermal interface which dissipates 100 W at an ambient temperature of 22 °C. It is also shown that the use of additional means of active cooling in combination with LHPs allows to increase the value of dissipated heat up to 180 W and to decrease the system thermal resistance down to 0.29 °C/W
