Of course, in some other embodiments, due to the difference of the heat management system or the difference of the working condition, the high-temperature fluid and the low-temperature fluid are not limited to the high-temperature refrigerant and the low-temperature refrigerant in the above-mentioned embodiments, the high-temperature fluid includes the refrigerant directly discharged from the outlet of the compressor and the refrigerant discharged from the outlet of the condenser in addition to the refrigerant discharged from the outlet of the compressor and passing through the throttle, and the low-temperature fluid includes the refrigerant after the throttle valve in front of the evaporator in addition to the refrigerant discharged from the outlet of the evaporator.

[0021] In the above embodiment, the high-temperature fluid and the low-temperature fluid are mixed in the premixing flow channel before entering the gas-liquid separator, instead of being directly mixed in the gas-liquid separator, which is beneficial to reduce boiling in the gas-liquid separator, avoid generating larger noise, and facilitate gas-liquid separation of the fluid in the gas-liquid separator, preventing too much liquid proportion of the refrigerant from directly entering the compressor and damaging the compressor. In addition, the heat exchange efficiency of the high-temperature fluid and the low-temperature fluid in the gas-liquid separator in the boiling state is low, the high-temperature fluid and the low-temperature fluid are mixed in the premixing flow channel before entering the compressor, compared with being directly mixed in the gas-liquid separator, the mixing path of the two fluids is increased, and the premixing flow channel has a smaller volume than the gas-liquid separator chamber, which is beneficial to the sufficient mixing of the high-temperature fluid and the low-temperature fluid, and improves the heat exchange efficiency between the high-temperature fluid and the low-temperature fluid.

Specifically, in the present embodiment, only the groove recessed away from the second plate body 12 is provided on the first plate body 11, and the second plate body 12 is a flat plate. The first plate body 11 and the second plate body 12 are fixedly welded, and the wall of the first flow channel 101, the wall of the second flow channel 102, and the wall of the premixing flow channel 110 are located on the wall of the groove and the second plate body 12. In other words, the first flow channel 101, the second flow channel 102, and the premixing flow channel 110 all extend along the plane perpendicular to the thickness direction of the flow channel assembly 1. In addition, the flow channel assembly 1 has a first hole 104 penetrating through the first plate body 11 or the second plate body 12 along the thickness direction, and the first hole 104 communicates the premixing flow channel 110 with the liquid inlet flow channel 20 of the gas-liquid separator 2. In the present embodiment, the premixing flow channel 110, the first hole 104, and the liquid inlet flow channel 20 of the gas-liquid separator 2 can all mix the high-temperature fluid and the low-temperature fluid, which increases the mixing path of the high-temperature fluid and the low-temperature fluid, and is beneficial to heat exchange. In addition, the premixing flow channel 110 is arranged at the groove of the first plate body 1, which has less space limitation for arranging the premixing flow channel 110.

In the embodiment, the angle a between the central axis direction of the first opening 1010 and the central axis direction of the second opening 1020 is less than fifty degrees, of course, the angle a can be smaller, or the central axis of the first opening 1010 and the central axis of the second opening 1020 are parallel.

[0026] In addition, in some embodiments, referring to Figure 2 , Figure 4 and Figure 5 , the flow channel assembly 1 includes a turning part 113, the wall forming the premixing flow channel 110 includes the turning part 113, the first opening 1010 and the second opening 1020 are both towards the turning part 113, the high-temperature fluid, the low-temperature fluid or the mixed fluid impacts the turning part 113, and is turned at the inner circumferential wall of the turning part 113, so as to enter the first hole channel 104, the inner circumferential wall of the turning part 113 surrounds part of the first hole channel 104, referring to Figure 5 , the radius of the inner circumferential wall of the turning part 113 is less than or equal to the radius of the first hole channel 104, or, referring to Figure 4 , along the axis direction of the first hole channel 104, the wall of the turning part 113 and the wall of the first hole channel 104 are connected by an arc surface, the wall of the first hole channel 104 is not suitable to be arranged far from the turning part 113, in this way, after the fluid impacts the turning part 113, it is easy to generate a turbulent flow in the area between the turning part 113 and the wall of the first hole channel 104, and part of the fluid is gathered in this area rather than smoothly entering the first hole channel 104, which is not conducive to the mixing between the high-temperature fluid and the low-temperature fluid.
