摘要： The invention relates to an inner heat exchanger for high-pressure refrigerants which is also used as an accumulator or refrigerant collector in air conditioning circuits. The inner heat exchanger includes an outer cylinder arranged and an inner cylinder arranged therein. The inner cylinder is designed as a bent flat sheet or tube with microchannels for refrigerant under high pressure. The liquid refrigerant under low pressure is collectable within the inner cylinder. Between inner cylinder and outer cylinder are formed channels in which the vaporous refrigerant under low pressure flows from a low-pressure inlet to a low-pressure outlet.

摘要： Systems and methods to cover sensitive areas of downhole tools including a downhole tool having an outer surface including a first position and a second position on the outer surface of the downhole tool, the outer surface having a sensitive area, a downhole sensitive element positioned along the outer surface of the downhole tool at the sensitive area, a movable cover operatively connected to the downhole tool and movable relative to the sensitive area, a control unit configured to generate an activation signal, and an activation mechanism operable in response to the activation signal, the activation mechanism configured to move the movable cover relative to the sensitive area from the first position to the second position, wherein the movement of the movable cover from the first position to the second position one of increases or decreases a portion of the sensitive area covered by the movable cover.
