A traditional T-shaped inlet flow channel can cause the flow of cooling liquid flowing into a parallel radiator group to be non-uniform, the closer to a cooling liquid inlet, the more the flow of the cooling liquid flowing into a radiator, and otherwise, the less the flow of the cooling liquid flowing into the radiator. When the distribution of the flow flowing into the parallel radiators is unbalanced, the temperatures of the parallel heat source groups are different, and the temperature difference between the heat source groups is caused. The more the parallel connection number is, the larger the temperature difference between the heat source sets is, and the short plate effect is more obvious. A traditional T-shaped inlet ...
