Abstract:
1. Evaporator for a cooling circuit for cooling at least one heat emitting device by evaporation of a cooling fluid, said evaporator comprising: a top collector having a volume for receiving the cooling fluid therein; a bottom collector having a volume for receiving the cooling fluid therein; an evaporator body, comprising, a plurality of return channels fluidly connected to the bottom collector and to the top collector, each of the return channels comprising a respective return channel intake for intake of the cooling fluid from the top collector in the operating state, and a respective return channel outlet for letting out the cooling fluid to the bottom collector in the operating state; a liquid outlet port at the bottom collector for connection to a condenser of the cooling circuit for letting in cooling fluid directly from the condenser to the bottom collector in an operating state of the evaporator; and a vapor outlet port connectable to a condenser of the cooling circuit for letting out cooling fluid from the top collector towards the condenser in the operating state, wherein the top collector has a separation volume for separating, in the operating state, a predominantly liquid portion from a predominantly vaporous portion of the cooling fluid therein, and the vapor outlet port of the evaporator is arranged for letting the predominantly vaporous portion of the cooling fluid out of the top collector, and wherein the return channel intakes are arranged for taking in the predominantly liquid portion of the cooling fluid from the top collector,
