Abstract

The invention discloses a high-efficiency evaporative fin heat exchanger, comprising a gas-collecting pipe, a collecting pipe and a gas outlet pipe. One end of the collecting pipe is formed by integrating the gas-collecting pipe through a plurality of loops and a plurality of branches derive from the other end of the collecting pipe and each branch is communicated with the plurality of loops to be integrated into the vent pipe. For the high-efficiency evaporative fin heat exchanger provided by the invention, the liquid refrigerant is converted into gaseous refrigerant in the fin heat exchanger; the mass velocity of the refrigerant is maintained but the volume velocity changes along with the changing of the refrigerant density during the process; the liquid refrigerant is converted into gaseous refrigerant under heat-absorbing in the evaporative fin heat exchanger; as the enlarging of the specific gravity of the gaseous refrigerant, the volume velocity of refrigerant rises gradually; when the specific gravity of the gaseous refrigerant occupies three loops, the conversion is finished through a pant-type three-way; and the heat transmission coefficient is enhanced and the increase of one loop occupied by refrigerant reduces the manufacturing cost of the unit while the specific gravity of the gaseous refrigerant rises.

Description

(1) Technical field [0001] The invention relates to the technical field of fin heat exchangers, in particular to a high-efficiency evaporative fin heat exchanger suitable for air-conditioning units. (2) Background technology [0002] Conventional evaporative fin heat exchangers adopt a multi-input and multi-outlet method. The flow resistance loss of the refrigerant during the evaporation process in the heat exchanger is uneven, and the flow volume flow rate of liquid refrigerant and gaseous refrigerant in the heat exchange tube is very different. , causing the heat transfer coefficient of the liquid refrigerant in the heat exchange tube to be greatly reduced. (3) Contents of the invention [0003] The technical problem solved by the invention is to provide a high-efficiency evaporative fin heat exchanger suitable for air-conditioning units, which can not only improve the heat transfer coefficient of liquid refrigerant in the heat dissipation process, but also avoid the pro...
