Embodiment Construction
[0037] Please refer to Figure 5 As shown, the present invention discloses a heat exchanger 100, which includes an inlet header 1, an outlet header 2, several flow pipes 3 between the inlet header 1 and the outlet header 2, And several fins 4 arranged between adjacent flow tubes 3 . In the illustrated embodiment of the present invention, the heat exchanger 100 is a microchannel heat exchanger, and the flow tube 3 is a flat tube.
[0038] The inlet header 1 and the outlet header 2 are parallel to each other and located on two sides of the heat exchanger 100 . In order to improve the compressive strength of the entire heat exchanger 100, the inlet header 1 and the outlet header 2 are both cylindrical.
[0039] Please refer to Image 6 and Figure 7As shown, the flow pipe 3 is roughly rectangular, which includes a first end surface 31, a second end surface 39, a top wall 32, a bottom wall 33, two side walls 34, and a wall between the top wall 32 and the bottom wall 33. Chann...

A heat exchanger comprises an inlet flow collecting pipe, an outlet flow collecting pipe and a plurality of circulating pipes, wherein the inlet flow collecting pipe is provided with punched holes in which the circulating pipes are inserted and an inner side surface positioned on the side opposite to the side of the punched holes; each circulating pipe comprises passages and a first end inserted into the inlet flow collecting pipe from the corresponding punched hole; a first end surface opposite to the inner side surface is arranged at the first end; notches penetrating through each first end surface are formed in a top wall positioned at the first end; the passages partially expose to the notches; a refrigerant main passage is formed between the first end surface and the inner side surface in the axial line direction of the inlet flow collecting pipe; refrigerant distributing passages are formed by the notches and the passages in the direction perpendicular to the axial line direction. The heat exchanger has the benefits that through the arrangement of the notches, larger area of the passages can be exposed, so that the distribution of fluid can be relatively uniform.
Description
technical field [0001] The invention relates to a heat exchanger and belongs to the field of microchannel heat exchangers. Background technique [0002] Please refer to Figure 1 to Figure 3 As shown, the existing microchannel heat exchanger 100' usually includes an inlet header 1', an outlet header 2', several flat tubes 3' connecting the two headers, and several flat tubes arranged between adjacent flat tubes. Fin 4'. The inlet header 1' is provided with a distribution pipe 5'. The inlet header 1' and the outlet header 2' are arranged in parallel. The flat tubes 3' are arranged parallel to each other. [0003] Please refer to figure 2 and image 3 As shown, the flat tube 3' is roughly rectangular, which includes two end faces 31', a top wall 32', a bottom wall 33', two side walls 34', and a tube located between the top wall 32' and the bottom wall 33'. There are several microchannels 35', and the microchannels 35' are separated from each other by several partitions ...
