The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In one embodiment, referring to fig. 1 and 5, a spiral heat exchanger 100, the spiral heat exchanger 100 includes: a heat exchange pipe 110, a first joint 120, and a second joint 130. The heat exchange tube 110 has a heat exchange axis 111 thereon, and the heat exchange tube 110 includes a first tube segment 112 and a second tube segment 113 integrally communicated with each other. The first tube section 112 and the second tube section 113 both start from the connection end between the first tube section 112 and the second tube section 113, surround the heat exchange axis 111, and extend helically along the same orientation in the length direction of the heat exchange axis 111. The first tube segment 112 and/or the second tube segment 113 are formed with a cavity 116 for placement of the combustor 700. The first joint 120 and the second joint 130 are respectively communicated with the first pipe section 112 and the second pipe section 113.
In the spiral heat exchanger 100, the first pipe section 112 and the second pipe section 113 are respectively spirally wound around the heat exchange axis 111 by the heat exchange pipe 110, so that the obtained double-spiral structures are all arranged around the same axis, and the phenomenon that the double-spiral structures are independently separated to cause overlarge transverse occupied space is avoided. Because the first tube section 112 and the second tube section 113 both extend spirally from the connecting end between the first tube section 112 and the second tube section 113 along the same direction in the length direction of the heat exchange axis 111, the spiral structure formed by the first tube section 112 and the spiral structure of the second tube section 113 can be interwoven or sleeved together, so that the heat exchange tube 110 is compact as a whole, heat can be effectively absorbed and utilized between the first tube section 112 and the second tube section 113, and the heat exchange efficiency is improved. Meanwhile, the first pipe section 112 and the second pipe section 113 are communicated in an integrated manner, so that a rivet-free interface, a flange or a welding joint is arranged in the formed heat exchange pipe 110, the water leakage risk is reduced, the potential safety hazard is reduced, and the safety performance of a product is improved. In addition, the first pipe section 112 and the second pipe section 113 are both spiral from the connecting end between the first pipe section 112 and the second pipe section 113 along the same direction, so that the first joint 120 and the second joint 130 are both positioned at the same side of the heat exchange pipe 110, the water inlet and outlet and the mounting port of the burner 700 are mounted on the same plane, the mounting space can be saved, and the burner 700 is suitable for miniaturized products.
It should be noted that, when the first tube section 112 and the second tube section 113 are respectively screwed around the heat exchange axis 111, the rotation directions of the two can be the same (i.e. both right-handed rotation and left-handed rotation); or may be different (i.e., one left-handed and the other right-handed). When the rotation directions of the first pipe section 112 and the second pipe section 113 are different, the spiral structure formed by the first pipe section 112 is sleeved outside (at this time, the cavity 116 is formed by the second pipe section 113 in a spiral manner) or inside (at this time, the cavity 116 is formed by the first pipe section 112 in a spiral manner) the spiral structure formed by the second pipe section 113, which is an inner and outer layer long cylindrical structure. Furthermore, the integral communication of the first pipe section 112 and the second pipe section 113 is to be understood as: the first pipe segment 112 and the second pipe segment 113 are of unitary construction, i.e. two parts on one pipe.
It should be noted that the longitudinal direction of the heat exchange axis 111 has two opposite directions, and for the sake of understanding, taking fig. 1 as an example, the longitudinal direction of the heat exchange axis 111 is the direction indicated by any arrow S in fig. 1. At this time, the first pipe section 112 and the second pipe section 113, when spiraled, each extend spirally in the direction indicated by the same arrow S in fig. 1.
Further, referring to fig. 1, the first tube segments 112 and the second tube segments 113 are along the same rotation direction and alternately surround the heat exchange axis 111. As can be seen, the first pipe section 112 and the second pipe section 113 extend spirally at intervals in the same rotational direction during the spiral forming. At this time, the helical structure formed by the first tube section 112 and the helical structure formed by the second tube section 113 are interlaced and overlapped to form a single-layer cylindrical structure, so that the space occupied by the heat exchange tube 110 in the whole heat exchanger is reduced on the premise of the same size of the cavity 116, and the miniaturization and the light weight of the product are realized.
Further, referring to FIG. 2, the first pipe section 112 forms a helical structure with an inner diameter d1The inner diameter d of the spiral structure formed with the second pipe section 1132The same, that is, the spiral structure formed by the first tube section 112 and the spiral structure formed by the second tube section 113 are perfectly combined to form a single-layer long cylindrical structure, so that the overall structure of the heat exchange tube 110 is more compact.
In one embodiment, referring to fig. 2, a tube gap 117 is left between the helical structure formed by the first tube segment 112 and the helical structure formed by the second tube segment 113. The tube gap 117 is used for the circulation of flue gases. During the heat exchange process, the hot fluid flows out of the tube gap 117 and flows around the tube walls of the first tube section 112 and the second tube section 113, so that the heat is sufficiently conducted to the cold fluid in the tubes, and effective heat exchange is realized.
Further, referring to fig. 2, the tube gap 117 is plural, and the plural tube gaps 117 are distributed at intervals along the length direction of the heat exchanging axis 111.
In one embodiment, referring to fig. 1, the heat exchange tube 110 further includes a transition section 114. The first tube section 112 is integrally communicated with the second tube section 113 through a transition section 114, and the first tube section 112 and the second tube section 113 both start from the transition section 114, surround the heat exchange axis 111, and spirally extend along the same direction parallel to the length direction of the heat exchange axis 111. In this way, the transition section 114 makes the connection between the first pipe section 112 and the second pipe section 113 smoother, and simplifies the pipe winding operation of the first pipe section 112 and the second pipe section 113.
Specifically, the transition section 114 is any one of a straight tube, an S-shaped bent tube, and a disk-shaped spiral tube.
In one embodiment, referring to fig. 3, the first pipe segment 112 and the second pipe segment 113 are both bellows 115. The corrugated pipe 115 is adopted as the heat exchange pipe 110, so that the heat exchange area is increased, the heat exchange is more sufficient and uniform, and the heat exchange efficiency of the heat exchange pipe 110 is improved.
Further, referring to fig. 3, the distance D between the peaks of the corrugated tube 115 is 3mm to 4mm, the height h of the valleys is 2.5mm, and the thickness of the tube wall of the corrugated tube 115 is 0.3 mm.
In one embodiment, referring to FIG. 4, the spiral heat exchanger 100 further includes a fixture 140. The spiral structure formed by the first tube segment 112 and the spiral structure formed by the second tube segment 113 are connected by the fixing member 140, so that the first tube segment 112 and the second tube segment 113 are stably connected by the fixing member 140, and the structural strength of the heat exchange tube 110 is improved.
Further, referring to fig. 4, a plurality of slots 141 are disposed on the fixing member 140. The plurality of catching grooves 141 are provided at intervals along the length direction of the fixing member 140. The clamping grooves 141 are used for clamping the first pipe section 112 or the second pipe section 113, so that in the fixing process, the pipe walls of the first pipe section 112 and the second pipe section 113 are respectively clamped into the corresponding clamping grooves 141, so that the first pipe section 112 and the second pipe section 113 are quickly connected.
Specifically, referring to fig. 4, the fixing member 140 includes a first fixing strip 142 and a second fixing strip 143. The first fixing strip 142 is connected end to end with the second fixing strip 143. The first fixing strip 142 is recessed along a direction away from the second fixing strip 143 to form a plurality of first recesses 1421. The second fixing strip 143 is recessed in a direction away from the first fixing strip 142 to form a plurality of second recesses 1431. The first recess 1421 and the second recess 1431 cooperate to form the card slot 141. The first fixing strip 142 and the second fixing strip 143 may be connected end to end by means of binding, welding, clamping, bolting, or integrally forming.
In one embodiment, referring to fig. 4, a first embedding portion 1422 is formed between two adjacent first recesses 1421, and a second embedding portion 1432 is formed between two adjacent second recesses 1431. The first embedding part 1422 and the second embedding part 1432 are respectively embedded in the tube gap 117, so that the tube gap 117 is ensured to be uniform, and the heat exchange tube 110 has a stronger and more reliable structure.
In one embodiment, referring to fig. 5, a heat exchange device comprises a heat exchange cartridge 200, a top member 300, a mounting member 400 and the spiral heat exchanger 100 of any of the above embodiments.

Because the first tube section 112 and the second tube section 113 both extend spirally from the connecting end between the first tube section 112 and the second tube section 113 along the same direction in the length direction of the heat exchange axis 111, the spiral structure formed by the first tube section 112 and the spiral structure of the second tube section 113 can be interwoven or sleeved together, so that the heat exchange tube 110 is compact as a whole, heat can be effectively absorbed and utilized between the first tube section 112 and the second tube section 113, and the heat exchange efficiency is improved. Meanwhile, the first pipe section 112 and the second pipe section 113 are communicated in an integrated manner, so that a rivet-free interface, a flange or a welding joint is arranged in the formed heat exchange pipe 110, the water leakage risk is reduced, the potential safety hazard is reduced, and the safety performance of a product is improved. In addition, the first pipe section 112 and the second pipe section 113 are both spiral from the connecting end between the first pipe section 112 and the second pipe section 113 along the same direction, so that the first joint 120 and the second joint 130 are both positioned at the same side of the heat exchange pipe 110, the water inlet and outlet and the mounting port of the burner 700 are mounted on the same plane, the mounting space can be saved, and the burner 700 is suitable for miniaturized products.

Meanwhile, the temperature of the top and the bottom of the heat exchange cylinder 200 is prevented from being too high, so that the user is effectively prevented from being scalded.

The second heat insulator 600 is installed on a side of the installation member 400 facing the heat exchange pipe 110. The materials of the first heat insulating material 500 and the second heat insulating material 600 are not particularly limited in this embodiment, and only need to have a heat insulating function.

Because the first tube section 112 and the second tube section 113 both extend spirally from the connecting end between the first tube section 112 and the second tube section 113 along the same direction in the length direction of the heat exchange axis 111, the spiral structure formed by the first tube section 112 and the spiral structure of the second tube section 113 can be interwoven or sleeved together, so that the heat exchange tube 110 is compact as a whole, heat can be effectively absorbed and utilized between the first tube section 112 and the second tube section 113, and the heat exchange efficiency is improved.
