The invention discloses a distributing cavity combined collecting and distributing tube for an automotive parallel flow evaporator, and relates to a heat exchanger element. The distributing cavity combined collecting and distributing tube comprises a tube body, a collecting and distributing tube cavity is connected with a distributing cavity sealing plate to form the tube body, a first collecting cavity and a second collecting cavity are axially formed in the collecting and distributing tube cavity, an arc-shaped cavity is formed between the first collecting cavity and the second collecting cavity, the distributing cavity sealing plate is an arc-shaped plate with the middle projecting upwards, connected onto the arc-shaped cavity of the collecting and distributing tube cavity and combined with the arc-shaped cavity to form a distributing cavity, harmonica-shaped tube mounting holes are uniformly formed in the bottoms of the first collecting cavity and the second collecting cavity, and overflowing holes are formed in one side or two sides of the arc-shaped cavity. Flow distribution is uniform, the heat exchange performance of the evaporator can be greatly enhanced, and the distributing cavity combined 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 exchanging element, in particular to a split cavity combined collector and split 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 ), but the he...
