THEORETICAL CALCULATION METHOD FOR POWDER CAPILLARY STRUCTURE OF LOOP HEAT PIPE WITH INVERTED MENISCUS
Organization of heat exchange in the evaporator of a loop heat pipe (LHP) by the principle of inverted menisci is connected with considerable non-uniformity of heat flow on an evaporating surface that reduces LHP operating characteristics.

| description | Organization of heat exchange in the evaporator of a loop heat pipe (LHP) by the principle of inverted menisci is connected with considerable non-uniformity of heat flow on an evaporating surface that reduces LHP operating characteristics. The paper considers a possible variant concerning decrease of this non-uniformity which is not connected with the usage of an internal surface of powder capillary structure that starts playing a role at partial drainage of a pore space. This variant presupposes creation of a system of vapor-outlet channels located inside of the capillary structure on some distance from the evaporator wall. The paper shows that such design of the LHP evaporator makes it possible to distribute heat flow on an evaporating surface much more uniformly and decrease a maximum heat flow density by several folds. Thus it is possible significantly to intensify a heat exchange process and increase a critical average heat flow and also reduce a temperature of an LHP evaporator body. |
