ZONES OF HEATING -- HEAT TRANSPORT -- SIMULTANEOUS DECREASE
Аннотация: Results are given of experimental investigations of an oscillating heat pipe (OHP) made in the form of a closed-loop coil of a copper capillary tube with an inside diameter of 2 mm, 4.5 m long, and filled with water in an amount of 50% of internal volume. The starting characteristics of OHP are studied in the range of heat loads from 30 to 100 W under conditions of cooling by way of natural and forced air convection. The pattern of temperature pulsations in the zones of heating, heat transport, and cooling is investigated. It is found that temperature pulsations exhibit a chaotic pattern. In cooling of an OHP by way of natural convection, the increase in heat load is accompanied by an increase in the maximal temperature of the heating zone with a simultaneous decrease in the nonuniformity of the temperature field. When an OHP is cooled by way of forced convection, a decrease in the maximal temperature of the heating zone is observed; however, this is accompanied by an increase in the amplitude of temperature pulsations and in the nonuniformity of the temperature field

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.

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

AIRCRAFTS -- LOOP HEAT PIPE -- ELECTRONIC BOX -- PASSIVE COOLING SYSTEM
Аннотация: The paper represents the results of development and thermal tests of a cooling system of a seat electronic box, managing the in-flight entertainment system used aboard commercial aircrafts. The system is completely passive and consists of two conventional copper-water miniature heat pipes and two miniature loop heat pipes with R-141b as a working fluid. Two crossbeams of a passenger seat made of aluminum alloy cooled by means of free air convection were used as heat sinks. At the maximum heat load of 100 W the cooling system provides a temperature of a cooled object at a level of not above 81°C at the ambient temperature of 22°C, which is 4°C below that of the maximum specified temperature

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
