AI Technical Summary
In battery thermal management systems, the problem of uneven refrigerant distribution in existing heat exchangers is particularly evident when the refrigerant enters multiple parallel channels in a gas-liquid two-phase state, resulting in uneven refrigerant distribution within each channel, which becomes more pronounced as the number of channels increases.
A uniform refrigerant structure is designed, including a refrigerant inlet channel and a refrigerant flow channel inside the core. By setting openings on the top sidewall of the refrigerant inlet channel that correspond one-to-one with the refrigerant flow channels inside the core and setting them at intervals along the vertical direction, the lowest point is spaced apart from the lowest point of the refrigerant inlet channel to form a liquid accumulation structure. Combined with the stacked assembly and tube structure, the uniform deposition and distribution of liquid refrigerant in the inlet channel is ensured.
By designing the liquid accumulation structure and stacked fin assembly, the residence time of the liquid refrigerant in the refrigerant inlet channel is guaranteed, and the flow rate of the refrigerant in each core channel is evenly distributed, solving the problem of uneven refrigerant distribution and improving heat exchange efficiency.
