Overview:
The water-cooled screen is an efficient liquid-cooled heat insulation component specially designed for thermal field systems in the photovoltaic industry. It is widely used in equipment such as single crystal furnaces, polycrystalline furnaces, and PECVD reaction furnaces to regulate temperature field distribution, isolate thermal radiation, and stabilize the crystal growth environment. The product circulates cooling water in the water channel to Take away the radiant heat of the furnace cavity, effectively controlling the cavity temperature and improving equipment operation efficiency and finished crystal quality. The product structure can be customized into ring type, cylinder type, baffle type, sleeve type, etc. as needed.
Working Principle:
The water-cooled screen adopts a closed circulating cooling water system. Cooling water flows in the internally set flow channel, continuously absorbing thermal radiation from high-temperature areas (such as heating elements, heat sources), and Export heat to the external cooling system. Its role is equivalent to establishing a "cooling isolation zone" between the heat source and the equipment wall, thereby forming a stable temperature gradient zone, controlling the thermal field morphology, and ensuring the directional growth of crystals.
Features:

Core component for thermal field optimization: Adjusts temperature gradient and improves crystal yield.
Flexible structural form: Multiple shapes and interface methods, adapting to various furnace types and layouts.
Manufactured with high-strength materials: Uses high-temperature resistant copper, stainless steel, aluminum alloy and other materials to ensure long-term stable operation.
High cooling efficiency: Scientific design of flow channels, small water resistance, and strong heat dissipation capacity.
Excellent sealing performance: Tight welding, pressure-resistant and leak-proof, supporting high-load continuous operation.
Supports customized development: Size, interface, and cooling section can be customized as needed to meet the differentiated needs of different equipment.
Note: Water-cooled screens are divided into regular type and special type. Both regular type and special type include ordinary models and models with pits on the inner wall. The ordinary model and the model with pits on the inner wall are the same except that the inner wall of the cone is densely covered with pits.
