Problems solved by technology

If the liquid flow distance is too long, it will inevitably cause the temperature difference between the inlet and outlet, resulting in uneven heat dissipation or local overheating
At the same time, in a system with a large rated flow rate, the pressure drop of the S-shaped water channel will cause the flow rate to fail to reach the rated flow rate, resulting in overheating and damage to electronic equipment

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...

Abstract

The invention discloses a heat dissipation panel with variable-width water channels. The heat dissipation effect of each water channel is balanced through changing the widths of the water channels; the water channel far away from a main inlet and a main outlet is gradually widened; and one or more S-shaped water channel is used at one side near the main inlet and the main outlet. According to theheat dissipation panel with the variable-width water channels, the targets of more uniform temperature distribution and a better heat dissipation effect can be achieved.

Description

technical field [0001] The invention specifically relates to a cooling plate for variable-width water channels. Background technique [0002] Due to its small size and high heat dissipation performance, liquid cooling devices are widely used as cooling devices for high-power electronic equipment. Existing liquid cooling plates, such as the Chinese patent CN105658027A "Liquid cooling plate for cooling electronic components", use a plurality of "S-shaped" serial water channels connected end to end to ensure consistent flow rates, and at the same time add grooves in the water channels to Increase the cooling area. If the liquid flow distance is too long, it will inevitably cause the temperature difference between the inlet and outlet, resulting in uneven heat dissipation or local overheating. At the same time, in a system with a large rated flow rate, the pressure drop of the S-shaped water channel will cause the flow rate to fail to reach the rated flow rate, resulting in ov...
