Liquid cooling system is one of the most effective ways to dissipate heat, which can dissipate hundreds of watts to kilowatts. The liquid cooling plate of the manufacturer's standard pipeline directly contacts with the bottom plate of the equipment to be cooled by placing the coolant pipe, which can reduce the number of heat exchange interfaces between the equipment and the coolant, thus maintaining the minimum thermal resistance and improving the performance.
Vacuum brazing type water cooling plate, process introduction: CNC or other ways to process water cavity, vacuum brazing for surface sealing. CNC finished product processing. Features: higher process threshold (surface welding), more flexible design structure, better performance (double-sided heat source), high reliability. Defects: high welding requirements, high finished products, low production efficiency.
Type 1 emphasizes heat dissipation. The fin structure is used in the fluid path to increase the contact area with the coolant, thus improving the heat conduction performance. Products with vacuum brazing structure, can provide customized configuration.
The water cooling panel adopts machining method, and the internal flow channel size and path can be freely designed. It is suitable for thermal management products with large power density, irregular heat source layout and limited space. It is mainly used in the design of heat dissipation products in the fields of wind power converter, photovoltaic inverter, IGBT, motor controller, laser, energy storage power supply, supercomputer server, etc, However, it is seldom used in power battery system.
The water cooling plate for onshore wind power system comprises a base plate, a solder plate and a cover plate. The filler metal plate and the cover plate are successively arranged on the base plate to form a sealed cavity and a flow channel with the base plate. The base plate is provided with a shunt groove, a plurality of parallel S-shaped water cooling flow channels and a linear water cooling flow channel. The shunt groove is provided with a water inlet joint, and the linear water cooling flow channel is provided with a water outlet joint, The cold water can flow into several parallel S-shaped water cooling channels through the inlet joint and the shunt slot, forming a return circuit in each S-shaped water cooling channel, and finally converging into the linear water cooling channel and flowing out through the outlet joint. Serrated fins are set in each S-shaped water cooling channel. The water cooling plate adopts fins with small flow and high efficiency heat exchange, combined with multiple S-shaped channels, Thus, the pressure loss of the water cooling system is reduced, and the temperature uniformity of different power modules is satisfied, which greatly improves the stability of the wind power generation system and reduces the additional power loss.
