Working principle: the low-temperature liquid flows in the liquid cooling flow channel to absorb heat transferred by the battery for cooling, and the flow speed of the liquid is regulated through the pore plate structure arranged in the liquid cooling flow channel, so that the liquid flows more uniformly.
In order to flow to everywhere fast after liquid fills the liquid cooling board, the liquid cooling inboard part is left regional and right regional, separates through the baffle between left regional and the right regional, and is equipped with the import and export of a liquid on left regional and the right regional respectively, and liquid can be according to actual conditions follow two import and export input, and can not lead to the heat dissipation to receive the influence because of the flow direction of liquid is different.
In order to enable the liquid in the two areas to circulate, the temperature of the liquid cooling plate is more uniform, through gaps are formed in the partition plate and used for enabling the liquid in the left area and the liquid in the right area to flow and communicate, and the problem that the liquid in the two areas is basically consistent can be guaranteed due to the fact that the liquid in the two areas circulates.
In order to better control the flow of the liquid, so as to ensure that the flow velocity of the liquid is consistent with the flow path, the liquid cooling flow channels in the left area and the right area are in mirror image distribution, and the mirror image flow channel distribution can ensure that the flow velocity and the flow path of the liquid after flowing in are the same, thereby ensuring the heat dissipation synchronization and ensuring that the heat dissipation is more uniform.
In order to control the flow rate and the flow velocity of the liquid, the width of the liquid cooling flow channel in the liquid cooling plate is the same.
In order to better predict and control the flow rate of liquid flowing through the orifice plate structure, the shape of the orifice plate structure is a regular pattern, and the regular pattern is easy to ensure consistency, so that the flow rate of the liquid flowing through the orifice plate structure is basically the same.
The beneficial effects are that: compared with the prior art, the liquid cooling plate has the advantages that the plurality of liquid cooling flow channels which are parallel and uniformly distributed are arranged in the liquid cooling plate, meanwhile, the pore plate structure is arranged in the liquid cooling flow channels, and the left area and the right area which are arranged in a mirror symmetry mode are further arranged, so that the flowing and the flow speed of liquid in the liquid cooling flow channels are more uniform, heat dissipation is effectively carried out, and the temperature uniformity of the liquid cooling plate is ensured.
