Abstract

um sistema de refrigeração (1) que compreende: - um circuito de refrigeração (2) para refrigerar um motor de combustão (3) por meio de um refrigerante que circula no circuito de refrigeração; - um radiador (6) para refrigerar o refrigerante; - uma bomba centrífuga (5) para circular o refrigerante no circuito de refrigeração; e - uma câmara de circulação (28) fornecida no circuito de refrigeração imediatamente a montante de uma entrada de bomba (9a) da bomba. o circuito de refrigeração compreende um primeiro canal (7) para transportar o refrigerante do radiador para a entrada da bomba (9a) e um segundo canal (10) através do qual o refrigerante pode circundar o radiador. uma extremidade a jusante (29) do primeiro canal e uma extremidade a jusante (30) do segundo canal são conectadas tangencialmente à câmara de circulação (28) a partir de diferentes direções para, deste modo, produzir um fluxo de refrigerante em circulação na câmara de circulação e na entrada da bomba (9a).a refrigeration system (1) comprising: - a refrigeration circuit (2) for cooling a combustion engine (3) by means of a refrigerant circulating in the refrigeration circuit; - a radiator (6) for cooling the refrigerant; - a centrifugal pump (5) for circulating refrigerant in the refrigeration circuit; and - a circulation chamber (28) provided in the cooling circuit immediately upstream of a pump inlet (9a) of the pump. the cooling circuit comprises a first channel (7) for conveying the radiator refrigerant to the pump inlet (9a) and a second channel (10) through which the refrigerant may surround the radiator. a downstream end (29) of the first channel and a downstream end (30) of the second channel are tangentially connected to the circulation chamber (28) from different directions to thereby produce a circulating refrigerant flow in the chamber circulation and pump inlet (9a).
