Abstract

placa de cavitação para proteger um componente de aquecimento e detectar uma condição. de acordo com exemplos, um aparelho pode incluir uma câmara fluídica, em que um fluido deve ser temporariamente mantido. o aparelho pode também incluir um componente de aquecimento para gerar calor para formar uma bolha de impulso no fluido mantido na câmara fluídica e uma placa de cavitação pode ser fornecida entre a câmara fluídica e o componente de aquecimento. a placa de cavitação pode estar em comunicação com a câmara fluídica e pode separar fisicamente a câmara fluídica do componente de aquecimento para proteger o componente de aquecimento. além disso, um controlador pode determinar uma condição na câmara fluídica com base em um sinal elétrico recebido da placa de cavitação.
