It should be understood that the fluid flow channel 4 can also be a pipeline.

[0032] like Figure 3-Figure 4 As shown, the spiral coil heat exchange assembly 1 includes a spiral coil 1-1, a first flow divider box 1-2, a second flow divider box 1-3, an inner cylinder 1-4 and an outer cylinder 1-5, Figure 1The inner cylinder 1-4 is arranged adjacent to the surrounding cylinder 2-1, and the outer cylinder 1-5 is arranged adjacent to the container 5. The first diversion box 1-2 and the second diversion box 1-3 are annular structures with the same structure respectively arranged on the radial outer sides of the upper and lower ends of the inner cylinder 1-4. The spiral winding tube 1-1 is wound between the first diversion box 1-2 and the second diversion box 1-3 on the outer side of the inner cylinder 1-4 and is connected with the first diversion box 1-2 and the second diversion box 1-3. The outer cylinder 1-5 is arranged on the outer side of the spiral winding tube 1-1 and its outer surface is flush with the outer surfaces of the first diversion box 1-2 and the second diversion box 1-3. In the present embodiment, the first diverter box 1-2 and the second diverter box 1-3 have the same structure, and diverter holes 1-2-3, 1-3-3 are provided on the end faces facing the spiral winding tube 1-1.

In the present embodiment, the outer cylinder 1-5 and the container 5 are independently provided. It should be understood that the outer cylinder 1-5 and the container 5 can be combined, that is, the container 5 is directly used as the outer cylinder 1-5 of the spiral winding heat exchange component 1.

[0033] Among them, the first diversion box 1-2 has sixteen first through-tubes 1-2-1 evenly spaced circumferentially to connect the mixing chamber 8 to the inner cylinder 1-4 and the outer cylinder 1-5, and the second diversion box 1-3 has sixteen second through-tubes 1-3-1 evenly spaced circumferentially to connect the lower chamber 6 to the inner cylinder 1-4 and the outer cylinder 1-5. In the specific use process, the primary side fluid (i.e., the heat source side) flows between the inner cylinder 1-4 and the outer cylinder 1-5 through the outside of the spiral winding tube 1-1, flows through the second through-tube 1-3-1, the lower chamber 6, the thermal energy system 2 and the upper chamber 7 in sequence, flows through a section of the pipeline, enters the fluid power equipment 3, and then enters the fluid flow channel 4, the mixing chamber 8 and the first through-tube 1-2-1 in sequence, and finally returns to the outside of the spiral winding tube 1-1 to form a cycle. It should be understood that the number and position of the through-tubes 1-2-1 and 1-3-1 here are only for example and not for limitation.

The second diverter box 1-3 has four second interfaces 1-3-2 arranged at 90° intervals from each other, and the second diverter hole 1-3-3 is arranged in the middle of the second through-tubes 1-3-1 adjacent to each other. In the specific use process, the secondary side fluid (i.e., the heat load side or the cold side) enters the second diverter box 1-3 through the second interface 1-3-2, enters the tube of the spiral winding tube 1-1 through the second diverter hole 1-3-3, and then enters the first diverter box 1-2 through the first diverter hole 1-2-3, and finally flows out through the first interface 1-2-2.

[0035] In this way, the primary side fluid and the secondary side fluid complete the inter-wall heat exchange through the wall surface of the spiral winding tube 1-1, that is, the primary side fluid transfers heat to the secondary side fluid through the inter-wall heat exchange in the heat exchange device. Compared with the independent spiral winding tube heat exchanger structure in the prior art, the present invention realizes the flow diversion of the two fluids through the diverter box 1-2, 1-3, the structure is centralized and unified, and the overall compactness is improved.

It should be understood that the three-layer structure here is only an example and not a limitation. For example, a two-layer structure is also feasible, as long as the spiral tubes of each layer of spiral tube bundle are closely arranged in parallel and the spiral directions of the two adjacent layers of spiral tubes are opposite.

When the support bar 1-6 is arranged between the spiral winding tube 1-1 and the inner cylinder 1-4, the support bar 1-6 is welded to the inner cylinder 1-4. When the support bar 1-6 is arranged between two adjacent layers of spiral winding tubes 1-1, the two adjacent support bars 1-6 are welded to each other, such as Fig. 9 As shown. One side of the support bar 1-6 is grooved, and the groove direction is toward the spiral winding tube 1-1 close to the outer layer.

A plurality of clamps are provided on one side of the support bar 1-6. The opening direction of the clamps is toward the other side of the interlayer support bar 1-6. The opening shape cooperates with the spiral winding tube 1-1 close to the outer layer. The other side of the support bar 1-6 is flat and welded to the support bar 1-6 close to the inner layer.
