[0063] It should be understood that the connection arrangement means that the first heat exchange member 64 and the second heat exchange member 65 can be integrally formed with the heat exchange pipe 63, or can be separately formed and then connected together by processing. The heat exchange pipe 63, the first heat exchange member 64, and the second heat exchange member 65 are all arranged around at least part of the first cylinder 1.

The first flow guide structure 641 can be arranged on only one side of the first heat exchange member 64, or can be arranged on both sides of the first heat exchange member 64. The first flow guide structure 641 has a flow passage for the first fluid inside, and / or a flow passage for the first fluid is formed between adjacent two first flow guide structures 641. The second heat exchange member 65 includes a second flow guide structure 651 protruding from the surface of the second heat exchange member 65. The second flow guide structure 651 can be arranged on only one side of the second heat exchange member 65, or can be arranged on both sides of the second heat exchange member 65. The second flow guide structure 651 has a flow passage for the first fluid inside, and / or a flow passage for the first fluid is formed between adjacent two second flow guide structures 651.

[0065] The first heat exchange member 64 and the second heat exchange member 65 have different structures. The structure of the first heat exchange member 64 includes one or more combinations of the shape of the first flow guide structure 641, the distribution density of the first flow guide structure 641, and the thickness of the first heat exchange member 64. The shape of the first flow guide structure 641 can be one or more combinations of a strip structure, a corrugated structure, a sawtooth structure, a zigzag structure, a louver structure, a needle structure, a perforated structure, any structure with protrusions, and any structure with grooves on the surface, as long as the purpose of guiding the flow of the first fluid and increasing the heat exchange effect between the first fluid and the heat exchange assembly 6 can be achieved.

[0066] The structure of the second heat exchange member 65 includes one or more combinations of the shape of the second flow guide structure 651, the distribution density of the second flow guide structure 651, and the thickness of the second heat exchange member 65. The shape of the second flow guide structure 651 can be one or more combinations of a strip-shaped structure, a corrugated structure, a sawtooth structure, a zigzag structure, a louver structure, a needle-shaped structure, a perforated structure, any structure with protrusions, and any structure with grooves on the surface, as long as the purpose of guiding the flow of the first fluid and increasing the heat exchange effect between the first fluid and the heat exchange assembly 6 can be achieved.

[0067] The first flow guide structure 641 of the first heat exchange member 64 is a plurality of hollow strip-shaped structures arranged side by side, each of which extends along the axis direction of the fluid management assembly 100. The strip-shaped structure and the space between adjacent two strip-shaped structures form flow channels, and the strip-shaped structure guides the first fluid to flow in a straight line from top to bottom. The second flow guide structure 651 of the second heat exchange member 65 is a zigzag structure, and the space between adjacent two zigzag structures forms flow channels. The strip-shaped structure guides the fluid to flow in an S shape from top to bottom. In other embodiments, the first heat exchange member 64 and the second heat exchange member 65 can have other shapes.

[0068] In this embodiment, the flow guide member 8 is arranged between the first and second collecting pipes 61 and 62 and the second cylinder 2 to prevent the first fluid from flowing out of the first cavity 10 through the gap between the first and second collecting pipes 61 and 62 and the second cylinder 2. The flow guide member 8 can be connected to the first heat exchange member 641 or not. The present application does not limit this, which can be set according to the specific application environment.

[0069] The flow guide member 8 includes at least two parts located at the upper end of the first collecting pipe 61 and the lower end of the first collecting pipe 61, which prevents the first fluid flowing out of the third cavity 30 from flowing downward through the gap between the first and second collecting pipes 61 and 62 and the second cylinder 2 to flow out of the first cavity 10, i.e., the first fluid can flow through the heat exchange member 64 and the outside of the heat exchange pipe 63 as much as possible, thereby facilitating the improvement of the heat exchange efficiency of the fluid management assembly 100.

[0070] The flow guide 8 comprises a first matching surface 81 matched with the second cylinder 2, a second matching surface 82 matched with the first manifold 61, and a third matching surface 83 matched with the second manifold 62. Optionally, the first matching surface 81 can be matched with the second cylinder 2, i.e. the first matching surface 81 is a curved surface, which can effectively prevent the first fluid from flowing out of the first cavity 10 from the gap between the flow guide 8 and the inner wall surface of the second cylinder 2. The second matching surface 82 and the third matching surface 83 are provided with a protruding rib 84, one side of the wall surface of the protruding rib 84 extends to connect the second matching surface 82, and the other side extends to connect the third matching surface 83. The protruding rib 84 is arranged in the gap between the first manifold 61 and the second manifold 62, one side of the wall surface of the protruding rib 84 is matched with the first manifold 61, and the other side is matched with the second manifold 62. The second matching surface 82 is matched with the first manifold 61, and the third matching surface 83 is matched with the second manifold 62, which can effectively prevent the first fluid from flowing out of the first cavity 10 from the gap between the first manifold 61, the second manifold 62, and the flow guide 8.

[0071] When the fluid management assembly 100 works, in the cooling mode, the flow direction of the second fluid is as follows: the second fluid flows into the heat exchange pipe 63 from the sixth through hole 44 through the second manifold 62, flows along the heat exchange pipe 63 to the first manifold 61, and finally flows out of the fluid management assembly 100 from the fifth through hole 36; in the heating mode, the flow direction of the second fluid is as follows: the second fluid flows into the heat exchange pipe 63 from the fifth through hole 36 through the first manifold 61, flows along the heat exchange pipe 63 to the second manifold 62, and finally flows out of the fluid management assembly 100 from the sixth through hole 44. Thus, the second fluid completes the entire heat exchange process. In the first cavity 10, the second fluid flowing in the inner cavity of the heat exchange pipe 63 and the first fluid flowing in the first cavity 10 exchange heat.

[0072] In another embodiment of the present application, referring to Figure 15 As shown in the figure, the heat exchange assembly 6' comprises a spiral pipe 61', which is at least partially wound on the outer wall surface of the first cylinder 1. The cross section of the spiral pipe 61' is circular, and of course, the cross section of the spiral pipe can also be other shapes, such as polygonal structure, corrugated structure, etc. One end of the spiral pipe 61' is in communication with the fifth through hole 36, and the other end is sealed and in communication with the sixth through hole 44.

[0073] Figure 16 is a connection diagram of the heat management system of the exemplary embodiment of the present application. The direction indicated by the arrow is the fluid flow direction, and the heat management system is in the cooling mode. Please refer to Figure 16As shown, a heat management system includes a fluid management assembly 100, a first evaporator 200, a compressor 300, a first condenser 400 and a throttling device 500. The outlet of the first condenser 400 is communicated with the third through hole 35, the first head 3 of the fluid management assembly 100 is communicated with the flow guide pipe 5, the compressor 300 is communicated with the flow guide pipe 5 through the second head 4 of the fluid management assembly 100, and the inlet of the compressor 300 is communicated with the fourth through hole 43. The first evaporator 200 is connected with the heat exchange assembly 6 through the second head 4 of the fluid management assembly 100, the outlet of the first evaporator 200 is communicated with the fifth through hole 36, the throttling device 500 is connected with the heat exchange assembly 6 through the second head 4 of the fluid management assembly 100, and the inlet of the throttling device 500 is communicated with the sixth through hole 44. In the refrigeration mode, the fluid flowing out of the first evaporator 200 flows into the heat exchange assembly 6 in the fluid management assembly 100, exchanges heat with the fluid in the second cavity, and then flows out to enter the compressor 300. The high-temperature gaseous fluid flowing out of the compressor 300 exchanges heat in the first condenser 400, flows through the first cylinder 1 in the fluid management assembly 100, exchanges heat with the heat exchange assembly 6 through the flow guide pipe 5, and then flows out of the fluid management assembly to enter the throttling device 500. The throttled fluid exchanges heat in the first evaporator 200 again, and then flows into the fluid management assembly 100 to complete a heat exchange cycle. After heat exchange, the temperature of the fluid flowing in the heat exchanger 6 is increased, so that the temperature of the fluid entering the compressor 300 is increased, and the temperature of the fluid flowing into the throttling device 500 is reduced, thereby improving the refrigeration effect of the evaporator 200.

[0074] In the heating mode, the high-temperature gaseous fluid flowing out of the compressor 300 exchanges heat in the second condenser 400', flows through the first cylinder 1 in the fluid management assembly 100, and then enters the fluid management assembly 100 to exchange heat. The gaseous-liquid refrigerant after heat exchange enters the second evaporator 200' after throttling, and then enters the fluid management assembly 100. The fluid flows into the compressor 300 to complete a heat exchange cycle.

[0075] It should be understood in the present application that the above-mentioned first fluid and second fluid are both refrigerants. The first fluid is the refrigerant flowing out of the first evaporator 200, and the second fluid is the refrigerant flowing out of the condenser 400 or the throttling device 500. Two separate heat exchange systems are required for the fluid operation.

[0076] In the present document, "approximately" means that the similarity is more than 50%. For example, the first cylinder 1 is approximately cylindrical, which means that the first cylinder 1 is a hollow cylinder. The side wall of the first cylinder 1 can be provided with recessed parts or protruding structures, and the cross-sectional profile of the first cylinder 1 is not circular, but 50% of the profile is composed of an arc.
