Cyclic atomizing distribution device for evaporation side heat exchanger and cyclic atomizing method for cyclic atomizing distribution device

The invention discloses a cyclic atomizing distribution device for an evaporation side heat exchanger and a cyclic atomizing method for the cyclic atomizing distribution device. The cyclic atomizing distribution device is arranged at a position close to a joint of a distribution pipe and a pre-evaporation pipe in the distribution pipe of a cooling system, and is a flared throat pipe. A space between the inner wall of the distribution pipe and the outer wall of the flared throat pipe forms an un-atomized coolant sedimentation accumulation area which is communicated with an inner cavity of the flared throat pipe through a communicating opening reserved in the pipe of the flared throat pipe. The device has the effect that a coolant is converted into an atomized state before the flow distribution of parallel heat exchangers, so that the adverse effects of gravity on the distribution are eliminated or reduced. The device and the method have the characteristics of high distribution uniformity of each path of heat exchanger at high and low ends, low cost, no requirements for a great number of basic experiments, high universality, applicability of one structure to various types, simple process, low failure rate and the like.
