Of course, in some other embodiments, the heat exchanger 100 and the compressor assembly 2 can also be located on the same side of the flow channel part 12 in the thickness direction.

[0108] In order to reduce the heat leakage between the flow channel cavities, the present embodiment also proposes a thermal management integrated device, please refer to Figure 4 and Figure 15 In some embodiments, the thermal management integrated device includes a fluid management piece 1, and the fluid management piece 1 includes a flow channel part 12, and the flow channel part 12 has a heat insulation groove 12g and at least two flow channel cavities 120. The heat insulation groove 12g is located between two adjacent flow channel cavities 120, and the heat insulation groove 12g penetrates the flow channel part 12 along the length direction of the flow channel part 12. In the present application, the fluid management piece 1 has the heat insulation groove 12g and the at least two flow channel cavities 120, and the heat insulation groove 12g is located between two adjacent flow channel cavities 120. By using the heat insulation groove 12g to insulate the two adjacent flow channel cavities 120, the heat transfer from the high-temperature side to the low-temperature side can be reduced, thereby reducing the heat leakage between the flow channel cavities 120.

[0109] Please refer to Figure 6 , Figures 11 to 13In some embodiments, the cross section of the heat insulation groove 12g is consistent along the length direction of the heat insulation groove 12g; wherein the heat insulation groove 12g is formed by extrusion mold in one step with the flow channel part 12, and no subsequent machining process is needed, which can reduce the processing difficulty. At this time, the fluid management member 1 is an extrusion member, and the length direction of the heat insulation groove 12g is consistent with the extrusion direction of the fluid management member 1. In some embodiments, the length direction of the flow channel part 12 is also consistent with the extrusion direction of the fluid management member 1, so that the heat insulation groove 12g and the flow channel part 12 can be integrally extruded. The length direction of the flow channel part 12 and the heat insulation groove 12g is the extension direction of the flow channel part 12 and the heat insulation groove 12g. The flow channel part 12 can be made of aluminum or aluminum alloy by extrusion molding. The aluminum extrusion molding is a plastic processing method for forcing aluminum billets to produce directional plastic deformation by applying a large pressure to the aluminum billets placed in the mold cavity or extrusion cylinder, so as to extrude from the die hole of the extrusion mold, thereby obtaining a part or semi-finished product with required cross-sectional shape, size and certain mechanical properties. The aluminum ingot is divided into several metal streams under the action of pressure, enters the welding chamber through the shunt hole, collects in the welding chamber, and is re-welded in a high-temperature, high-pressure and high-vacuum environment. Finally, it flows out through the gap between the core and the hole, thereby forming a pipe or hollow profile that meets the size and performance requirements. If bending is required, a bending tool is added to the rear equipment. According to the heat insulation requirement, the heat insulation groove 12g is designed between the adjacent flow channel cavities 120 during the extrusion molding of the flow channel part 12.

[0110] Please refer to Figure 15 In some embodiments, the heat insulation groove 12g has a first opening 121g at both ends. Both ends of the heat insulation groove 12g are open structures, and the opening of the heat insulation groove 12g can be communicated with the naturally flowing air, which can reduce the heat leakage between the flow channel cavities 120 by using air as a heat insulation layer. In some embodiments, the cross section of the heat insulation groove 12g is rectangular, and in other embodiments, the cross section of the heat insulation groove 12g can also adopt other shapes.

[0111] Please refer to Figure 17 In some embodiments, the fluid management member 1 includes a first support surface 1201 and a second support surface 1202, which are respectively located on both sides of the thickness direction of the flow channel part 12; along the thickness direction of the flow channel part 12, one side of the heat insulation groove 12g has a second opening 122g, which penetrates the first support surface 1201 or the second support surface 1202 of the flow channel part 12; please refer to Figure 17The side of the heat insulation groove 12g is in an open structure. Specifically, in some embodiments, the cross section of the heat insulation groove 12g is in a U shape, and the heat insulation groove 12g has openings at one side facing the first support surface 1201 and both ends. The first opening 121g at both ends of the heat insulation groove 12g and the second opening 122g at one side can be communicated with the air flowing naturally, and the air is used as a heat insulation layer to reduce the heat leakage between the flow channel cavities 120. Of course, in other embodiments, the cross section of the heat insulation groove 12g can also adopt other shapes.

[0112] Please refer to Figure 15 In some embodiments, the flow channel part 12 has a vacuum heat insulation cavity 12f located in the heat insulation groove 12g, and the fluid management member 1 further comprises a blocking member 12k connected with the flow channel part 12, and the blocking member 12k blocks the heat insulation groove 12g.

[0113] Please refer to Figure 15 In a specific embodiment, the blocking member 12k comprises a plug 12h located at least partially in the heat insulation groove 12g, and at least two plugs 12h block the heat insulation groove 12g, and the vacuum heat insulation cavity 12f is located between the adjacent two plugs 12h. In some embodiments, the two ends of the heat insulation groove 12g are blocked by the plugs 12h, and the vacuum heat insulation cavity 12f is formed in the heat insulation groove 12g between the plugs 12h after furnace welding, and the heat insulation is achieved by using vacuum. In the vacuum environment, due to the reduction of air pressure, the gas density decreases, and the average free path of gas molecules increases, and the collision frequency and intensity between gas molecules and the wall of the vacuum heat insulation cavity 12f are relatively weakened, so that the vacuum environment reduces the occurrence of convection and contact, two forms of heat transfer, thereby improving the heat insulation effect. The plug 12h can be connected with the flow channel part 12 by brazing, adhering, fastening, cooperating, interlocking, mounting, fixing or other ways. In a specific embodiment, the plug 12h is welded and fixed with the flow channel part 12. In some embodiments, after the heat insulation groove 12g is extruded, the solder and the plug 12h are arranged in advance at the place to be sealed, and the vacuum brazing furnace can realize the purpose of vacuumizing and brazing sealing to form the vacuum heat insulation cavity 12f in the heat insulation groove 12g. The plug 12h and the flow channel part 12 are fixedly connected in a full-welding sealing structure to ensure the reliability of the sealing. Of course, in other embodiments, after the heat insulation groove 12g is blocked by the plug 12h, it can also be directly brazed and sealed in the brazing furnace without vacuumizing, and at this time, the air layer closed in the heat insulation groove 12g can also achieve a certain degree of heat insulation effect.

[0114] Please refer to Figure 16In some embodiments, the plug 12h comprises a plug blocking portion 12a, and the plug blocking portion 12a is located in the heat insulation groove 12g. The cross section of the plug blocking portion 12a is perpendicular to the length direction of the heat insulation groove 12g. In some embodiments, the cross section of the plug blocking portion 12a, the plug 12h and the heat insulation groove 12g are all rectangular. In some other embodiments, the plug 12h further comprises a plug leading-in portion, and the plug leading-in portion is located at one end of the plug blocking portion 12a. The outer wall of the plug leading-in portion has a slope, which facilitates the installation of the plug 12h into the heat insulation groove 12g.

In some embodiments, all the heat insulation grooves 12g are arranged in parallel.

[0117] In some embodiments, the cross section of the flow channel cavity 120 is consistent along the length direction of the flow channel cavity 120. The flow channel cavity 120 has the same cross section along the length direction, which can be molded by an extrusion die at one time, and thus the subsequent machining process can be omitted, thereby reducing the processing difficulty.

At this time, the fluid management member 1 is an extruded member, and the length direction of the flow channel portion 12, the flow channel cavity 120 and the heat insulation groove 12g is consistent with the extrusion direction of the fluid management member 1.
