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.

The paper considers behaviour of material flows at stages of complicated logistic industrial and transport systems. Key parameters of logistic delivery schemes are analyzed in the paper. The paper estimates an influence of a time parameter on the level of transport and logistics costs and, as a consequence, on a final finished product.While determining a stock level it is necessary to know not only an intensity of material resource consumption by manufacturing process for a concrete period of time, but also a probability of non-observance of transport service terms and cost of stock storage. Stocks of mass cargoes are basically formed at first stages of industrial and transport system and cost of their storage is relatively insignificant. However deficit presence of the given resources influences on functioning of all subsequent interrelated stages of the industrial and transport system.Thus, a risk of deficit occurrence of the given resources can be probably reduced by creating a high stock rate. There is a processing of hi-tech component items (or half-finished products) at last stages of the industrial and transport system. Expenses on storage of such resources are usually high and possibility of their substitution by analogous ones is insignificant. At last stages a mobilization of facilities for provision of on-time delivery is more profitable that allows to save on stock arrangement.
