Embodiment Construction

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The principle and structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0038] With the progress of society, people's living demands are constantly improving and upgrading. In the past, due to the limitation of the level of science and technology, people only required the heat exchanger to have the heat exchange function, and did not take into account the shape, size, efficiency, energy consumption and other factors of the heat exchanger. However, with the continuous development of society, ...

Abstract

The invention discloses a liquid distributor, a heat exchanger and an air conditioner. The liquid distributor comprises a liquid distribution pipe, the liquid distribution pipe is encircled into a disc shape, a liquid inlet surface and a liquid outlet surface are sequentially formed in the direction perpendicular to the disc surface, and a plurality of liquid homogenizing holes are formed in the liquid inlet surface and the liquid outlet surface. According to the liquid distributor with a coil pipe structure, the contact area between the liquid distributor and a liquid refrigerant is increased, and an effective and uniform distributed film can be formed by utilizing the liquid distributor. Meanwhile, according to the heat exchanger, the heat exchange efficiency is greatly improved by improving the structure of heat exchange tubes and the position distribution of heat exchange assemblies.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a liquid distributor, a heat exchanger and an air conditioner. Background technique [0002] Horizontal tube falling film heat transfer technology was applied in the field of refrigeration technology in the 1990s. It has been widely used in the refrigeration industry market because of its advantages such as small refrigerant flow outside the tube, low temperature difference, high heat transfer efficiency, and simple and compact structure. To a certain extent, it can replace flooded heat exchangers and dry heat exchangers commonly used in small-capacity refrigeration equipment. [0003] In the flow process of falling film heat exchange, whether a stable and uniform liquid film can be formed on the surface of the heat exchange tube to avoid the occurrence of dry spots is the decisive factor defining the quality of falling film heat exchange. The quality of liquid film form...
