Abstract

"DISPOSITIVO DE CONTROLE DE FLUXO DE AR". Trata-se de um dispositivo de fluxo de ar que tem um elemento de amortecedor fixo e um elemento de amortecedor movível. Fios de memória de forma são conectados ao elemento de amortecedor fixo e ao elemento de amortecedor movível. Os fios de memória de forma são alternativamente eletrificados para causar a contração deste para mover o elemento de amortecedor movível em direções opostas. Um aquecedor pode ser fornecido junto com os elementos de amortecedor para superar o acúmulo de gelo em ambientes frios, como sistemas de refrigeração."AIRFLOW CONTROL DEVICE". It is an air flow device which has a fixed damping element and a movable damping element. Shape memory wires are connected to the fixed damping element and the movable damping element. The shape memory wires are alternately electrified to cause their contraction to move the movable damping element in opposite directions. A heater may be supplied with the damper elements to overcome ice build-up in cold environments such as refrigeration systems.
