Abstract

trata-se de uma ferramenta elétrica (500) com uma disposição de resfriamento que compreende uma tubulação de calor (520) para resfriar uma unidade de motor elétrico (510) da ferramenta elétrica. a tubulação de calor é preenchida com um fluido de trabalho que muda entre fases líquida e de vapor para transportar energia térmica para longe da unidade de motor (510). uma primeira extremidade (521) da tubulação de calor está localizada em contato térmico com a unidade de motor elétrico (510) e coleta calor da dita unidade de motor. o calor é, então, transportado para uma segunda extremidade (522) da tubulação de calor, a qual está em contato térmico com um dispositivo de resfriamento (530) disposto para ser resfriado por ar ambiente, tipicamente, por meio de um ventilador (532).
