Abstract

The invention relates to a double-row parallel flow evaporator and an air conditioning device with the evaporator. The double-row parallel flow evaporator comprises a first collecting pipe, a second collecting pipe, double rows of flat pipes and double rows of fins. A converging cavity is formed in the first collecting pipe. An input cavity and an output cavity are formed in the second collecting pipe. The first ends of the double rows of flat pipes are communicated with the converging cavity. The second ends of the double rows of flat pipes are communicated with the input cavity and the output cavity. An internal shunting input pipe is arranged in the input cavity, and multiple internal shunting input holes are distributed in the internal shunting input pipe. An internal shunting output pipe is arranged in the output cavity, and multiple internal shunting output holes are distributed in the internal shunting output pipe. The double-row parallel flow evaporator is simple and compact in overall structure; the operation that two parallel flow evaporators are assembled through connectors to form a double-row evaporator is not needed, production efficiency is high, and cost is low; and meanwhile, the second collecting pipe is in a double-internal-shunting manner, the air outflow uniformity of an air conditioner under the refrigerating and heating working conditions is guaranteed by adjusting the refrigerant amount passing different regions, and the comfort for a user to use the air conditioner is improved.

Description

technical field [0001] The invention relates to an evaporator, in particular to a double-row parallel flow evaporator and an air conditioner with the evaporator. Background technique [0002] The parallel flow heat exchanger is an all-aluminum heat exchanger assembled from aluminum flat tubes, aluminum fins and aluminum headers. It has high heat exchange efficiency, rich raw material resources and low cost, and the evaporator itself is resistant to electrochemical It has the advantages of high corrosion resistance and compact structure, and is currently widely used in automobile air-conditioning evaporators, and has also begun to be used in household air-conditioning single-cooling condensers and cabinet evaporators. [0003] In the application of cabinet evaporators, single row parallel flow evaporators are more common at present. In recent years, due to the continuous improvement of air conditioner capacity and energy efficiency requirements, the research and application ...
