MULTI-CHANNEL HEAT EXCHANGER WITH IMPROVED UNIFORMITY OF REFRIGERANT FLUID DISTRIBUTION

摘要

PURPOSE: A multi-channel heat exchanger with the improved distribution uniformity of a refrigerant fluid is provided to improve the distribution uniformity of a refrigerant fluid and to improve the performance of a micro path heat exchanger. CONSTITUTION: A multi-channel heat exchanger with the improved distribution uniformity of a refrigerant fluid comprises an inlet manifold(12) and an outlet manifold(14) and the inlet and outlet manifolds are connected by a plurality of parallel tubes. A distribution pipe(22) comprises a fist end portion, a closed second end portion, and a plurality of non-circular openings. The first end portion is connected to a refrigerant source. The second end portion is faced to the first end portion. The plurality of non-circular opening is installed in between the first and second end portions in a longitudinal direction of the distribution pipe. Each opening of the plurality of non-circular openings comprises one or more slots. [Reference numerals] (AA) Range
