HEAT PIPE -- WATER -- METHANOL
Аннотация: Results are given of development and investigations of a compact cooler for application in electronics, based on an open-loop oscillating heat pipe. The cooler operation is investigated, where water, methanol, and R141b Freon are used as working fluids under conditions of uniform and concentrated heat input. The effective operation of the device is demonstrated in the heat load range from 5 to 250 W. The “heat source-ambient air” minimal thermal resistance of 0.35°C/W was reached with water under uniform heat load of 250 W. The maximal value of heat load density is 75 W/cm2 with the heat flux concentration on the surface of 1 cm2, where methanol is used as working fluid

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.

HEAT TRAHSFER -- VAPOR FORMATION
Аннотация: The dependence of the heat transfer rate on the geometry of vapor channels is investigated analytically and experimentally with a consideration of the thermal contact resistance during vapor formation in fine porous structures for carrying away the vapor. It is shown that the larger the contact resistance, the greater the distance between the channels must be to maximize the values of the heat-transfer coefficients

LOOP THERMOSYPHON -- EVAPORATOR -- CAPILLARY STRUCTURE,
Аннотация: The objective of this work was to develop a device for cooling electronic elements with a heat power up to 30 W by its rejection and dissipation in the ambient by free air convection. The device specification assigned the temperature range of the ambient conditions from −40 to +105° C and the available space of 30(W) × 120(H) × 200(L) mm. As a result a hybrid scheme based on a loop thermosyphon was proposed, where the evaporator embodied the capillary structure. In such a scheme, the return working fluid flow was ensured by the combined action of the gravity and capillary forces. Several prototypes with different loop and evaporator designs were tested in laboratory conditions. Water and heptane were used as working fluids. The experiments showed that the role of the capillary structure locally placed in the evaporator can be efficiently implemented by both highly porous cellular materials and capillary grooves made on the evaporating surface. It is also shown that heptane can be effectively used as a working fluid which is appropriate for the temperature range requirements. At the same time the device has good mass-and-size characteristics and total thermal resistance under a nominal heat load of about 1.7° C/W

LOOP HEAT PIPE -- HEAT TRAHSFER -- EXPERIMENTAL STUDY
Аннотация: In order to dissipate the heat generated by electronic boxes in avionic systems, a copper–water LHP with a flat-oval evaporator was fabricated and tested at steady state. The LHP consists of a flat shaped evaporator, 7 mm thick, including compensation chamber with attached heat exchanger. The condenser is cooled by forced convection of liquid. The variable parameters are the heat sink and ambient temperatures (20 and 55 °C), the orientation (−90° to +90° in two perpendicular planes) and the power input (0–100 W). Evaporator wall temperatures are higher when the evaporator is placed above the condenser. For heat sink and ambient temperature of 20 °C the evaporator wall temperature does not vary much with heat load for all measured elevations. But it fluctuates at heat sink and ambient temperature equal to 55 °C when the evaporator is placed below the condenser. The LHP total thermal resistance is governed by the condenser resistance. It decreases with increasing heat load, whatever the operating conditions, because the part of the condenser internal surface area used for condensation increases too. A minimum thermal resistance of 0.2 K/W was obtained. The maximum thermal resistance was 2.7 K/W

ELECTRONICS COOLING -- LOOP HEAT PIPE -- FLAT–OVAL EVAPORATOR
Аннотация: A compact copper–water loop heat pipe (LHP) with an effective length of 310 mm equipped with a flat–oval evaporator measuring 80 (L) × 42 (W) × 7 (H) has been tested. The vapor line and the condenser had the same internal diameter of 5.4 mm. The internal diameter of the liquid line was 3.4 mm. Tests were conducted with a heat source which had a heating surface of 30 mm × 30 mm. The condenser was cooled by running water with a temperature of 20 °C. In the horizontal position the device has exhibited serviceability in the heat load range from 5 W to 1200 W at vapor temperatures from 26.5 °C to 103.4 °C. The maximum capacity was achieved at a heat source temperature of 143.5 °C, when the LHP thermal resistance was equal to 0.044 °C/W. The corresponding values of thermal resistance for the evaporator and the condenser were at a level of 0.006 °C/W and 0.038 °C/W. A minimum thermal resistance of 0.097 °C/W for the “heat source–LHP–cooling water” system was obtained at a heat load of about 700 W, at which the temperature of the heat source was 87 °C

AMMONIA MINIATURE -- LOOP HEAT PIPE -- FLAT EVAPORATOR
Аннотация: The paper presents the results of analysis, development and tests of an ammonia miniature loop heat pipe (MLHP) with a flat evaporator, which has an active-zone diameter of 30mm. The length and the diameter of the vapor and the liquid lines are 1m and 2/1.2mm. The device serviceability has been demonstrated at a horizontal and a vertical orientation in 1-g conditions. The maximum heat load achieved on trials was equal, respectively, to 160W and 120W, which corresponds to a heat flow in the evaporation zone of 23 W/cm 2 and 17 W/cm 2 . The minimum thermal resistance at nominal heat loads from 40 to 80 W varied in the range from 0.42 W/m 2 K to 0.59 W/m 2 K. A comparison has been made with a model MLHP with a cylindrical evaporator equipped with a copper and aluminum “sa

LOOP HEAT PIPES -- HEAT-TRANSFER DEVICE -- MINIATURE LOOP HEAT PIPE
Аннотация: Loop heat pipes (LHPs) are highly efficient heat-transfer devices, which have considerable advantages over conventional heat pipes. Currently, miniature LHPs (MLHPs) with masses ranging from 10-20 g and ammonia and water as working fluids have been developed and tested. The MLHPs are capable of transferring heat loads of 100-200 W for distances up to 300 mm in the temperature range 50-100°C at any orientation in 1-g conditions. The thermal resistance for these conditions are in the range from 0.1 to 0.2 K/W. The devices possess mechanical flexibility and are adaptable to different conditions of location and operation. Such characteristics of MLHPs open numerous prospects for use in cooling systems of electronics and computer systems

LOOP HEAT PIPES -- HEAT TRAHSFER -- ELECTRONICS COOLING
Аннотация: A series of tests have been carried out with a miniature loop heat pipe (mLHP), which has been developed for consumer electronics cooling, for horizontal and four vertical orientations under different sink temperatures. The mLHP has a cylindrical evaporator of 5 mm outer diameter and 29 mm length. The steady-state operating characteristics are similar for different orientations except for the orientation where the evaporator is above the compensation chamber. At an evaporator temperature of 75 °C, an evaporator heat load up to 70 W can be reached with thermal resistance of about 0.2 °C/W. The transient behavior of the mLHP is studied in detail. In general, the mLHP can be started up with very low power input (5 W). Big temperature oscillations in the liquid line were found in many cases, however, the temperature oscillations in the evaporator are minimum. The orientations greatly influence the operating characteristics of the mLHP. At least for the horizontal orientation, the overall performance of the tested mLHP is satisfying
