Abstract

The invention provides a liquid distribution structure with a shielding avoiding effect and a heat exchanger. The liquid distribution structure comprises a liquid distribution pipe; a heat exchange tube is arranged in the heat exchanger, and the liquid distribution pipe is annularly arranged above the heat exchange tube. According to the liquid distribution structure with the shielding avoiding effect and the heat exchanger, a liquid distribution disc structure in the prior art is replaced with the annular liquid distribution pipe, so that shielding of gaseous refrigerants is reduced under thecondition that the liquid distribution effect the same as that of the liquid distribution disc structure is guaranteed, and the heat exchange performance of the heat exchanger is guaranteed; and meanwhile, spraying holes are formed, the distribution area of the heat exchange tubes can be increased, the problem that a plurality of heat exchange dead zones exist due to the small distribution area of the heat exchange tubes in the prior art is effectively solved, shielding of a liquid distributor to the heat exchange tubes is reduced, limitation of the liquid distributor to the layout of the heat exchange tubes is reduced, the structure of the liquid distributor is simplified, occupied space is small, no liquid distribution dead angle exists, and the space utilization rate of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to a liquid distribution structure and a heat exchanger with the effect of avoiding shading. Background technique [0002] In the heat pump system unit, the falling film evaporator needs to have the function of both evaporation and condensation. The conventional liquid distributor structure is in the form of a whole rectangle or other forms of boxes. This structure can only meet the distribution requirements of the evaporation condition. Liquid effect and fluid flow mode. In the condensing condition, the high-temperature and high-pressure gaseous refrigerant enters the top of the shell reversely through the gas outlet of the original evaporation condition. The middle liquid distributor covers most of the heat exchange area, and the gaseous refrigerant cannot fully Contact with heat exchange tubes leads to poor heat exchange of some heat exchange tubes, resulting in l...
