- Figure 5 is a diagram showing the amount of heat transfer before applying the cut structure to the manifold fluid module according to an embodiment of the present invention
- Figure 6 is a diagram showing the amount of heat transfer after applying the cut structure to the manifold fluid module according to an embodiment of the present invention. This is a diagram showing the amount of heat transfer.
- the temperature of the portion of the manifold plate 1,100 where the low-temperature first fluid moves appears to be relatively high.
- the temperature of the portion where the low-temperature first fluid moves in the manifold plate 1,100 appears to be relatively low. This is because heat transfer from the high-temperature first fluid to the low-temperature first fluid is blocked by the cut structure. Additionally, heat transfer can be minimized by minimizing the section through which the low-temperature first fluid flowing into the evaporator inlet port 14 moves as much as possible.
- Main plate 2 First main plate
- first main plate 6 fluid inlet port
- first inlet stage 62 first outlet stage
- first heat transfer inhibition unit 92 second heat transfer inhibition unit
- bottom plate 110 first bottom plate
- connection part 120 second bottom plate 130: connection part
