Abstract
The invention discloses a three-dimensional cooling evaporative condensation heat exchanger, comprising at least one heat exchange plate; the heat exchange plate includes at least one heat exchange unit; the heat exchange unit includes spray cooling pipes, at least one heat exchange pipe, At least one cooling water pipe, the heat exchange pipe is pierced with a circulating water pipe, the cooling water is output to the outside of the spray coolingpipe through the water distribution hole and evenly distributed on the evaporation heat exchange surface to form a water curtain; the refrigerant transported in the refrigerant channel , while exchanging heat with the water curtain on the outer wall side of the heat exchange pipe, exchanging heat with the cooling water in the circulating water pipe, and exchanging heat with the cooling water in the cooling water pipe. The three-dimensional cooling evaporating and condensing heat exchanger of the present invention adopts a flat tube and seamless connection structure, which effectively solves the problem of poor water film formation on the surface of the heat exchange plate. The channel in the heat exchange tube is divided into multiple refrigerant channels by the circulating water pipe, so The heat exchange tube is divided into multiple heat exchange areas, which can make full use of the space and heat exchange surface of the refrigerant channel, effectively improve the heat exchange efficiency, and realize three-dimensional cooling, evaporation and condensation heat exchange.
Description
technical field [0001] The invention relates to the field of condensation heat exchangers, in particular to three-dimensional cooling evaporation condensation heat exchangers. Background technique [0002] Existing water-cooled chillers generally use shell-and-tube condensers or evaporative condensers; for evaporative condensers, for example: Chinese patent application CN2020104015228 discloses a cascade evaporative-condensing heat exchanger, which uses circular tubes and cloth Although the water tank can improve the heat exchange efficiency and reduce the volume of the heat exchanger, it still has the following problems: [0003] 1. The outer surface of the round tube heat exchange tube still has a small radian on the outer surface of the tube, which causes water accumulation in the depression formed between two adjacent heat exchange tubes, thus destroying the film-forming property of the cooling water, which is not conducive to the vaporization and evaporation of the cool...
