[0046] The present application further proposes a heat exchanger 01, such as Figures 4 to 6 As shown, Figure 4 is a top view schematic diagram of a second embodiment of the heat exchanger of the present application; Figure 5 yes Figure 4 A schematic side view of an embodiment;

[0047] Figure 6 yes Figure 4 Front view schematic diagram of the embodiment. Based on the first embodiment, the heat exchanger 01 of this embodiment further includes two side plates 30, the two side plates 30 are arranged corresponding to the two first pipe segments 11, the side plates 30 are arranged perpendicular to the first sub-pipe segments 111 in the corresponding first pipe segments 11, and the two side plates 30 are arranged at a second angle, which is complementary to the first angle; the projection of the side plate 30 on the first plane is located at the connection between the first pipe segment 11 and the second pipe segment 12.

[0048] Specifically, a heat exchange tube monomer 10 arranged in parallel and serpentine can be manufactured first, and no welding process is required between the tube sections. The side panels 30 are installed at the same time, and then the second tube section 12 is bent to make the second tube section 12 bend, thereby making the projections of the two first tube sections 11 on the first plane be set at a first angle to form a V-shaped structure. At this time, the angle between the two side panels 30 will also be adjusted to the second angle.

[0049] The beneficial effect of this arrangement is that the side plate 30 can provide support for the deformation and bending of the heat exchange tube monomer 10 during the manufacturing process of the heat exchanger 01, thereby improving the convenience of bending and shaping the heat exchange tube monomer 10; and it helps to fix the relative positions of the multiple first sub-segments 111 and the multiple second sub-segments 112, so that the heat exchange tube monomer 10 can be bent more specifically at the second tube segment 12 during the bending and shaping manufacturing process without affecting the relative positions of other structures, so that the multiple first sub-segments 111 and the multiple second sub-segments 112 of each first tube segment 11 can maintain a fixed relative position while following the bending of the second tube segment 12 to smoothly complete the displacement, thereby reducing the difficulty of the manufacturing process of the heat exchange tube monomer 10; and during normal use, the setting of the side plate helps to fix the relative positions of the multiple first sub-segments 111 and the multiple second sub-segments 112 of the heat exchanger 01, thereby improving the structural stability and anti-interference performance of the heat exchanger 01, and improving the quality of the heat exchanger 01.

[0083] Different from the prior art, the heat exchanger of the present application includes a heat exchange tube monomer and a fin. The heat exchange tube monomer includes two first tube segments and a second tube segment. The two ends of the second tube segment are respectively connected to the two first tube segments. The projections of the two first tube segments on the first plane are arranged at a first angle, in a V-shape, which can expand the space around the heat exchanger, thereby expanding the flow space of the inflowing gas around the heat exchanger and reducing the fluctuation of the air volume. The projections of the two first tube segments on the first plane are arranged at a first angle, in a V-shape, which can expand the surface area of ​​the heat exchange tube monomer in contact with the inflowing gas, thereby increasing the heat exchanger. Heat exchange efficiency; and the projections of the two first pipe sections on the first plane are arranged at a first angle, in a V-shaped arrangement, which can expand the surface area of ​​the heat exchange tube monomer in contact with the surrounding air, thereby reducing the ash blockage, thereby reducing the performance degradation caused by the ash blockage, thereby improving the quality of the heat exchanger; and the projections of the two first pipe sections on the first plane are arranged at a first angle, in a V-shaped arrangement, which can expand the surface area of ​​the heat exchange tube monomer in contact with the surrounding air, thereby reducing the ash blockage, thereby reducing the performance degradation caused by the ash blockage, thereby further reducing the distance between the fins, and adding more fins , improving the tightness of the fin structure, thereby increasing the surface area of ​​the heat exchanger for heat exchange with the inflowing gas, thereby improving the heat exchange efficiency of the heat exchanger and achieving high performance; and the projections of the two first pipe sections on the first plane are arranged at a first angle, in a V-shaped arrangement, so that the pipe section of the heat exchange tube monomer located at the downwind port can directly contact the inflowing gas and perform heat exchange, thereby improving the heat exchange efficiency of the heat exchange tube monomer; because the pipe sections of the heat exchange tube monomer do not need to use welding technology, it can improve the problems of heat exchange medium leakage caused by multi-tube welding, thereby improving the quality of the heat exchanger; The projections of the two first pipe segments on the first plane are arranged at a first angle, in a V-shaped arrangement, with a simple structure, a small bending angle, low energy consumption in manufacturing, a simple process, no need for large-scale processing equipment, and cost savings; the projections of the two first pipe segments on the first plane are arranged at a first angle, in a V-shaped arrangement, and the bending angle of this structure is easy to change, and it is easier to adapt to different heat exchanger sizes, increasing the scope of application; the fins are arranged on the outer wall of the first pipe segment, and the second pipe segment is not provided with fins, which can reduce the manufacturing difficulty of the second pipe segment bending process, thereby reducing the manufacturing difficulty of the heat exchanger and reducing the cost. Therefore, the present application can improve the heat exchange efficiency of the heat exchanger, improve the quality of the heat exchanger, and has a simple structure, which can reduce the process difficulty and reduce the cost.
