Both ends of the U pipe are welded with elbows 7 orshunt pipe assemblies 8 . The U-tube in the prior art is generally formed by bending a metal tube with a diameter greater than 5mm. The formed U-tube has only one refrigerant channel inside, and the cross-section of the refrigerant channel is relatively large, which leads to the disturbance ability of the refrigerant in the refrigerant channel. It is weak, so that the heat of the refrigerant cannot be effectively transferred to the tube wall of the U tube, reducing the heat exchange effect; at the same time, the refrigerant is divided from the opening side of the U tube, and the diversion method is single, and the bending part of the U tube and the bend The tube will make the shunt resistance of the refrigerant larger, thereby affecting the heat exchange effect of the heat exchanger.

To the wall of theheat exchange tube 2, the heat exchange area is increased to improve the heat exchange effect. The two ends of theheat exchange tube 2 are divided by the collector tube 1 respectively, so that theheat exchange tube 2 can adopt a straight tube body, and theheat exchange tube 2 avoids the use of bending parts and elbows for diversion, and the diversion resistance becomes smaller.

the two collecting pipes are oppositely arranged at intervals and are arranged in parallel, a plurality of heat exchange pipes which are sequentially arranged at intervals are arranged between the two collecting pipes, two ends of each heat exchange pipe are respectively communicated with the two collecting pipes, and a plurality of refrigerant channels are formed inside each heat exchange pipe; a plurality of partition plates are arranged in each collecting pipe, each collecting pipe is partitioned into a plurality of chambers through the partition plates, and the chambers of the two collecting pipes are sequentially communicated through refrigerant channels of the heat exchange pipes to form a refrigerant flow path; the chamber comprises a first chamber and a second chamber, and the first chamber and the second chamber are respectively arranged at two ends of the refrigerant flow path;

an inlet tube in communication with the first chamber; and

an outlet tube in communication with the second chamber.

2. The heat exchanger as claimed in claim 1, wherein at least one fixing plate is provided in the heat exchange tube, the fixing plate extends along a length direction of the heat exchange tube, opposite sides of the fixing plate are fixedly connected to inner sidewalls of the heat exchange tube, respectively, and the interior of the heat exchange tube is partitioned by the fixing plate to form a plurality of refrigerant channels.

3. The heat exchanger as claimed in claim 2, wherein a reinforcing plate is provided in the heat exchange tube, the reinforcing plate extends along the length direction of the heat exchange tube, opposite sides of the reinforcing plate are fixedly connected with the inner side wall of the heat exchange tube, respectively, and the reinforcing plate and the fixing plate are staggered with each other to form a grid shape in the cross section of the heat exchange tube.

4. The heat exchanger of claim 3, wherein the heat exchange tube, the fixing plate and the reinforcing plate are of an integrally formed structure.

5. The heat exchanger according to any one of claims 1 to 4, wherein the inner side wall of the heat exchange tube is smooth or convex.

6. The heat exchanger according to any one of claims 1 to 4, wherein the heat exchange tube is a straight circular tube.

7. The heat exchanger of claim 1, further comprising a plurality of fins disposed in spaced apart relationship in sequence, each of said heat exchange tubes passing through a plurality of said fins in sequence.

8. The heat exchanger of claim 7, wherein the heat exchange tube is expanded with the fin by a tube expander.

9. The heat exchanger of claim 1, wherein said first chamber and said second chamber are located at opposite ends of the same header.

10. An air conditioner comprising an indoor unit and an outdoor unit, wherein the indoor unit or the outdoor unit comprises the heat exchanger according to any one of claims 1 to 9.
