The present invention discloses an evaporator (1000) of a diffusion-absorption cooling machine. The evaporator is characterized by comprising an evaporator head (1105) or cover extending to a jacket wall (1100) enclosing a jacket cavity (1400) which houses a plurality of evaporator tubes (1115); and a flow limiter adapted to receive a refrigerant via a refrigerant intake (1150) and causing at least approximately equable dispersion of the refrigerant into each of the plurality of evaporator tubes (1115), wherein the dispersal of refrigerant into the plurality of evaporator tubes (1115) takes place in a pressure-less manner.
