Abstract
The utility model provides a heat exchanger and an air conditioning device. The heat exchanger can be used as a condenser or an evaporator. Separating plates are arranged in a flow collecting pipe to form a plurality of distribution cavities in the flow collecting pipe. The distribution cavities are matched with a plurality of inlet pipes and outlet pipes, so that coolants are distributed, when a hot house is used, the coolants in the distribution cavities form vortexes which are sprayed upwards from spraying holes in the upper faces of the distribution cavities to form spraying flows, the coolants are micronized and evenly enter a flat pipe to form annular flows of good heat transfer effects, heat exchanging among portions are evenly carried out, and performance of the heat exchanger is improved. When a cooling room is used, gas coolants release heat to the outside continuously through a pipeline to form condensed liquid or gas-liquid two-phase liquid. The condensed liquid or the gas-liquid two-phase liquid enters the distribution cavities from spraying holes in the lower portions of the distribution cavities inside a first flow collecting pipe, and are discharged from the outlet pipes integrally. In addition, the diameters of coolant particles become smaller, so that impact of the coolant particles on the inner wall of pipes and collisions between particles are restrained, and therefore noises of flowing of the coolants can be reduced.
