Embodiment
[0022] like figure 1 As shown, the existing radiator plate water channel includes coolant inlet 1, coolant outlet 2 and multiple "S-shaped" serial water channels 3 connected end to end. Due to the long distance of liquid flow, the temperature difference between the inlet and outlet is caused. This results in uneven heat dissipation or localized overheating.
[0023] like figure 2 As shown, a heat dissipation plate of a variable-width water channel of the present invention balances the heat dissipation effect of each water channel by changing the width of the water channel. One or more S-shaped water channels 6 are used on one side of the outlet 5;
[0024] The basic design parameters of the variable width water channel include: total flow, length of cooling plate, width of cooling plate, depth of water channel, width of total inlet and outlet water channel;
[0025] Pressure drop for parallel channels:
[0026] For laminar flow:
[0027] For turbulent flow:
[002...
