Referring to fig. 1 to 10, the present invention discloses a soot deposition resistant heat exchanger 100, which includes a first core 1, a second core 2, an inlet header 3, an outlet header 4, a connecting pipe 5 connecting the first core 1 and the second core 2, and a support 6.

The first core 1 is arranged in a serpentine shape, the first core 1 includes a plurality of first flat tubes 11 arranged at intervals along a first direction D1-D1 (e.g., up-down direction), and the first flat tubes 11 extend along a second direction D2-D2 (e.g., left-right direction) perpendicular to the first direction D1-D1. The first flat tubes 11 are parallel to each other. The first core 1 includes a first U-shaped connecting portion 12 connecting every two adjacent first flat tubes 11, and the first U-shaped connecting portion 12 is located at two ends (e.g., left and right ends) of the first core 1 along the second direction D2-D2.

The second core 2 is arranged in a serpentine shape, the second core 2 comprises a plurality of second flat tubes 21 arranged at intervals in the first direction D1-D1, and the second flat tubes 21 extend in the second direction D2-D2. The flat pipes 21 of the plurality of second are parallel to each other, and the flat pipes 11 of the plurality of first and the flat pipes 21 of the plurality of second are parallel to each other. The first core 1 and the second core 2 are stacked in a third direction D3-D3 (e.g., front-rear direction) perpendicular to the first direction D1-D1 and the second direction D2-D2. The second core 2 includes a second U-shaped connecting portion 22 connecting every two adjacent second flat tubes 21, and the second U-shaped connecting portions 22 are located at two ends (e.g., left and right ends) of the second core 2 along the second direction D2-D2.

Referring to fig. 4, the first flat tubes 11 of the first core 1 and the second flat tubes 21 of the second core 2 are arranged in a staggered manner along the first direction D1-D1.

The dust deposition resistant heat exchanger 100 is not provided with any fin connected with the first flat pipe 11 and the second flat pipe 21, so that dust deposition can be resistant, and maintenance is facilitated. In addition, compared with the traditional iron wire tube heat exchanger, the dust deposition resistant heat exchanger 100 has higher heat exchange efficiency.

The first core 1 is in fluid communication with the inlet header 3, and the second core 2 is in fluid communication with the outlet header 4.

The connection tube 5 is arranged obliquely with respect to the second direction D2-D2. The connecting tube 5 includes a first end 51 connected to the first core 1 and a second end 52 connected to the second core 2, wherein the first end 51 and the second end 52 have different heights. Referring to fig. 4, in the illustrated embodiment of the present invention, the first end 51 is lower than the second end 52. In the illustrated embodiment of the present invention, the first core 1, the second core 2, and the connection pipe 5 are integrally formed by bending a flat pipe, so that the structural strength is improved and the cost is reduced. In one embodiment of the present invention, the first core 1 and the second core 2 may be bent at one time, thereby improving production efficiency.

In the illustrated embodiment of the present invention, the stand 6 includes a base 61 and a support frame 62 detachably connected to the base 61. The base 61 includes a socket 611 and a locking surface 612 at the bottom. In addition, the base 61 is further provided with a mounting hole 613 for fixing the soot deposition heat exchanger 100 to another component.

By such an arrangement, the base 61 is favorably connected with the first core 1 and the second core 2, so as to improve the structural reliability of the dust deposition resistant heat exchanger 100. Compared with the prior art, the base 61 of the present invention includes the first sidewall 618 and the second sidewall 619 for limiting the first core 1 and the second core 2 from two sides, so that the first core 1 and the second core 2 can be better limited, and the structural reliability of the soot deposition resistant heat exchanger 100 is improved. In the illustrated embodiment of the present invention, the first sidewall 618 is located at one side of the first core 1 and is used for limiting the first core 1. The first sidewall 618 is a non-elastic structure. The second side wall 619 is formed by the latch arm 616, and the latch arm 616 is an elastic structure. With this configuration, the chassis 61 is locked from only one side when being engaged with the first core 1 and the second core 2 by the non-elastic structure and the elastic structure, thereby facilitating assembly and disassembly.

The support frame 62 includes a base 620 and a plurality of band clamps 621 protruding from the base 620 in opposite directions. The base 620 is located between the first core 1 and the second core 2, and the plurality of flat tube clamps 621 on the same support frame 62 are arranged in a staggered manner along the longitudinal direction (e.g., vertical direction) of the base 620. Each flat pipe clamp 621 is located the vertical plane, first flat pipe 11 and second flat pipe 21 are located the horizontal plane respectively, flat pipe clamp 621 is the perpendicular to first flat pipe 11 and second flat pipe 21. By arranging the flat pipe clamp 621 in the vertical plane, the area of deposited dust can be effectively reduced in the vertical direction, so that the dust deposition resistant heat exchanger 100 is more convenient to maintain. Each of the flat pipe clips 621 includes a catching groove 6211. Wherein the catching groove 6211 located at one side of the base 620 is used to fix at least part of the first flat tube 11 of the first core 1; the retaining groove 6211 on the other side of the base 620 is used to fix at least a part of the second flat tube 21 of the second core 2. Preferably, the first flat tube 11 and the second flat tube 21 are both retained in the corresponding retaining groove 6211 in an interference fit manner. In the illustrated embodiment of the present invention, the support frames 62 are two and are arranged side by side along the second direction D2-D2.

Each of the supporting brackets 62 includes a hook 622 inserted into the insertion hole 611. The hook portion 622 includes a first latch arm 6221, a second latch arm 6222, and a slot 6220 separating the first latch arm 6221 from the second latch arm 6222. The first locking arm 6221 is provided with a first step surface 6221a which is locked with the locking surface 612, and the second locking arm 6222 is provided with a second step surface 6222a which is locked with the locking surface 612. In the illustrated embodiment of the present invention, the hook 622 has a tapered surface that tapers from top to bottom to provide a certain guiding function, so as to facilitate the insertion of the hook 622 into the insertion hole 611. During the process of inserting the hook 622 into the insertion hole 611, the first and second latch arms 6221 and 6222 can deform into the slot 6220 under the guidance of the tapered surface, so that the first and second latch arms 6221 and 6222 approach each other, thereby facilitating the insertion into the insertion hole 611. After the hook 622 passes through the slot 6220, the first and second latch arms 6221 and 6222 recover their elastic forces, so that the first and second stepped surfaces 6221a and 6222a can abut against the latch surface 612. So set up for two the support frame 62 with the base 61 equipment forms a whole, reaches fixed and installation resistant deposition heat exchanger 100's effect.

The above embodiments are only for illustrating the invention and not for limiting the technical solutions described in the invention, and the understanding of the present invention should be based on the technical personnel in the technical field, and although the present invention has been described in detail by referring to the above embodiments, the technical personnel in the technical field should understand that the technical personnel in the technical field can still make modifications or equivalent substitutions to the present invention, and all the technical solutions and modifications thereof without departing from the spirit and scope of the present invention should be covered in the claims of the present invention.
