Abstract:
1. A heat absorber comprising: a plurality of evaporators serially connected in different positions for receiving heat generated at heat generation units, wherein each evaporator comprises: a) a liquid reservoir for accommodating liquid-phase working fluid; b) a liquid supply port for supplying liquid-phase working fluid to the liquid reservoir; c) a vapor ejection port for ejecting from the evaporator, working fluid vaporized at the evaporator; and d) a liquid ejection port for ejecting from the evaporator, liquid-phase working fluid accommodated in the liquid reservoir; a condenser in series with the plurality of evaporators; and a reservoir tank connected to an evaporator of the last position of the plurality of evaporators at the liquid ejection port and adapted to receive excess liquid-phase working fluid from the evaporator of the last position when a liquid-phase working fluid level is above a desired level and to supply liquid-phase working fluid to the evaporator of the last position when a liquid-phase working fluid level is below the desired level.
