Direct Cooling Battery Pack Liquid Cooling Plate To ensure uniform distribution of coolant, multiple aspects need to be considered and designed.
First, a reasonable flow channel layout can be adopted in the structural design of the liquid cooling plate. For example, a complex circuitous flow channel can be designed to allow the coolant to flow fully inside the liquid cooling plate and cover every area that needs cooling. By accurately calculating and simulating fluid flow, parameters such as the width, depth, and bending angle of the flow channel can be optimized to ensure that the flow rate and pressure of the coolant in different parts are basically consistent, thereby achieving uniform distribution. At the same time, multiple inlets and outlets can be set on the liquid cooling plate to increase the circulation path of the coolant and improve the uniformity of distribution.
Secondly, choosing a suitable coolant is also critical. The physical properties of the coolant, such as viscosity and thermal conductivity, will affect its flow characteristics in the liquid cooling plate. Low-viscosity coolant is easier to flow in the flow channel, reducing flow resistance and facilitating uniform distribution. In addition, some special additives can be added to improve the fluidity and wettability of the coolant, so that it can better contact the surface of the liquid cooling plate and improve the efficiency and uniformity of heat transfer.
Furthermore, the precision of the manufacturing process also has an important impact on the uniform distribution of the coolant. The processing precision of the liquid cooling plate should be high to ensure that the size and shape of the flow channel are accurate and avoid local blockage or deformation. Advanced welding technology and sealing technology are used to ensure the sealing of the liquid cooling plate, prevent coolant leakage, and ensure that the flow of coolant in the flow channel is not disturbed by external factors.
In addition, some auxiliary equipment and technologies can be used to achieve uniform distribution of coolant. For example, flow sensors and pressure sensors are installed to monitor the flow and pressure changes of coolant in the liquid cooling plate in real time, and the flow and pressure of the inlet and outlet are adjusted through the feedback control system to achieve the purpose of uniform distribution. Some flow equalizers or guide plates can also be set on the liquid cooling plate to guide the flow direction of the coolant so that it is more evenly distributed on the surface of the battery pack.
In short, Direct Cooling Battery Pack Liquid Cooling Plate needs to comprehensively consider multiple factors such as structural design, coolant selection, manufacturing process and auxiliary equipment to ensure the uniform distribution of coolant. By continuously optimizing and improving these aspects, the cooling effect of the liquid cooling plate can be improved to ensure the performance and safety of the battery pack.
