## 5 Experimental Verification  
### System Hardware Architecture  
This study used the designed fluid circulation heat dissipation system (as shown in Figure 1) to assemble the hardware components, as shown in Figure 11. Among them, the heat exchanger, compressor, radiator, pump, digital flow meter, and heat exchanger were purchased from the market, and the three key hardware components of the coolant storage tank, the diverter, and the QTRM were designed and manufactured for this study. The performance specifications of the hardware are shown in Table 6. The manufacturing instructions of the key hardware components are as follows:

The fabrication of the fluid cold plate was optimized according to A1B3C3, as obtained in Section 4.3. The aluminum alloy (6061-T6) material was selected for fabrication, according to its A1 size, and the integrated cold plate was formed by vacuum welding process bonding, as shown in Figure 12.

The main function of the shunt is to make the mass flow rate of the coolant flowing into each cold plate the same. Since there are four fluid cold plates in this system, a one-in and four-out shunt was designed for the flow control in this study. The hardware of the shunt is shown in Figure 13.
