Abstract

The invention discloses a double semilunar split collecting and distributing tube for an automotive parallel flow evaporator, and relates to a heat exchanger element. The double semilunar split collecting and distributing tube comprises a tube body, a collecting and distributing tube outer plate is connected with a collecting and distributing tube inner plate to form the tube body, two semilunar convex cavities are axially formed in the collecting and distributing tube outer plate, two semilunar cavities are axially formed in the collecting and distributing tube inner plate, the two semilunar convex cavities are combined with the two semilunar cavities to form two independent inner cavities including a first collecting cavity and a second collecting cavity, harmonica-shaped tube mounting holes are uniformly formed in the bottoms of the two semilunar cavities of the collecting and distributing tube inner plate, a distributing cavity is axially formed between the two semilunar convex cavities of the collecting and distributing tube outer plate of the tube body, and overflowing holes communicated with the first collecting cavity or the second collecting cavity are formed in one side or two sides of the distributing cavity. Flow distribution is uniform, the heat exchange performance of the evaporator can be greatly enhanced, and the double semilunar split collecting and distributing tube is simple in machining process, convenient to assemble, low in production cost and easy to popularize and use.

Description

technical field [0001] The invention relates to a heat exchange element, in particular to a double-half-moon split-type collecting and distributing tube of a parallel-flow evaporator for vehicles. Background technique [0002] With the continuous improvement of the manufacturing process, the car air-conditioning evaporator has successively appeared tube-sheet type, tube-belt type, stacked type, and parallel flow structure. There are mainly two types of evaporators with stacked and parallel flow structures. The heat exchange efficiency in the microchannel structure is higher than that of other structures, so there is a tendency to gradually replace the laminated structure. The collector pipe of the existing parallel flow evaporator is generally extruded as a whole to form two semi-arc tubes, which are connected by riveting to form an inner cavity, and flow hole spacers with various apertures are set in the inner cavity to make it play a role in shunting. role (see image 3 )...
