Abstract: This invention relates to heat recovery devices, namely of counter- flow plate heat exchangers wherein air is primarily used as medium. The claimed heat exchanger comprises a number of original solutions that improve its performance while reducing its weight and dimensions. The original pattern of seal application resolves - the task of creating end seals on heat exchanger plates. Flows in the claimed heat exchanger are separated using the seals. Meanwhile, the plates are identical and only differ by the position of bulges and the seal application pattern. The cold air flow travels through the heat exchanger without turns and pressure losses. The hot air flow is pre- separated into two flows and enters and exits the heat exchanger from two opposing sides. However, in other embodiments hot air can be inlet from one side through a single opening and outlet from another side through a single opening or other medium inlet patterns can be used. It helps maximize the utilization of the entire plate and improves the performance without an increase in the weight or dimensions of the heat exchanger.

Abstract: This invention relates to the area of refrigeration and serves the purpose of air dehumidification in closed air cycle refrigeration systems. The character of the claimed moisture separator comprises the separation of moisture in a closed casing wherein air moves from the bottom upwards. Air goes through a labyrinth formed by metal plates with area less than the area of the casing base. The plates are fastened to the opposing casing walls in an alternating pattern and are disposed at an angle to the perpendicular line of the casing. Thus, the plates form gaps in a fishbone pattern, and air passing through this labyrinth undergoes compression and expansion multiple times. The plates are interlaid with metal mesh that serves multiple purposes: moisture separator filter and means of snow/ice build-up aiding. The key feature of the claimed moisture separator is the mesh size changing from higher values (at the inlet, at the bottom of the casing) to lower values (at the outlet, at the top of the casing). The mesh is disposed between the plates in such a way that air cannot move beyond it in any way. A combination of various principles of moisture separation ensures a reliable and non-stop operation of the air cycle refrigeration unit within a wide temperature range (from +5 to -80°C) without excessive design complexities and with streamlined maintenance.
