Water-Cooled Panels: Industrial Heat Exchange Components

Product Specifications

Technical details and manufacturing context for Water-Cooled Panels

Definition

Water-cooled panels are specialized heat transfer components integrated into roof structures of industrial facilities to manage thermal loads. They function as part of larger cooling systems, typically consisting of metal plates or panels with internal water channels that absorb heat from equipment or processes and transfer it away via circulating coolant. These panels are commonly used in applications where direct liquid cooling is impractical or where space constraints limit the use of conventional heat exchangers. The panels are available in materials such as copper, aluminum, and stainless steel, each offering distinct thermal conductivity and corrosion resistance properties. The cooling capacity of a single panel ranges from 5 to 50 kW, with required water flow rates between 10 and 100 L/min. Operating pressure is specified between 1.0 and 1.6 MPa, while maximum operating temperature ranges from 120 to 200°C. Panel dimensions vary from 500 to 3000 mm in length and width, with thicknesses from 10 to 50 mm. Flatness tolerance is ±0.05 to ±0.2 mm per ISO 2768-mK, and surface roughness is Ra 0.8 to 3.2 μm per ISO 4287. Material grades include 6063-T5, 5052, and 304, referencing GB/T 3190 and ASTM B209. Weight ranges from 10 to 100 kg depending on size and material. Leakage rate is ≤0.01 mL/min at 1.5 times operating pressure, and pressure drop is 10 to 50 kPa at rated flow. These parameters are reference ranges and must be verified with the manufacturer for specific models. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

Water circulates through internal channels within the panel, absorbing heat through conduction from the panel surface. The heated water is then pumped to a heat exchanger or cooling tower where thermal energy is dissipated before the cooled water returns to complete the cycle. The efficiency of heat transfer depends on the thermal conductivity of the panel material, the flow rate, and the temperature difference between the panel surface and the coolant. Proper flow rate and pressure are essential to maintain turbulent flow and prevent hot spots. Regular monitoring of pressure drop and temperature differentials can indicate fouling or blockages. If the pressure drop exceeds the specified range or the cooling capacity diminishes, maintenance is required. The panels are designed to operate within the specified pressure and temperature limits; exceeding these can cause material degradation or leakage. The flatness and surface roughness are critical for ensuring good thermal contact with heat sources. Always verify that the operating conditions are within the manufacturer's specified limits.

Frequently Asked Questions

What are the typical materials used for water-cooled panels?

According to the directory data, water-cooled panels are available in copper, aluminum, and stainless steel. Each material has different thermal conductivity and corrosion resistance. The specific material grade options include 6063-T5, 5052, and 304, referencing GB/T 3190 and ASTM B209. Always confirm the material grade with the manufacturer for your application.

What is the operating pressure range for these panels?

The operating pressure is specified as 1.0 to 1.6 MPa. Above 1.6 MPa, material strength may degrade. Always verify the pressure rating with the manufacturer for the specific model.

How do I verify the flatness and surface roughness requirements?

Flatness tolerance is ±0.05 to ±0.2 mm per ISO 2768-mK, and surface roughness is Ra 0.8 to 3.2 μm per ISO 4287. These parameters are critical for thermal contact. You should measure these on the delivered panels and compare with the specified ranges. Confirm with the supplier that they meet these tolerances.

What maintenance signals indicate a problem with water-cooled panels?

Signs of trouble include increased pressure drop beyond the specified 10-50 kPa at rated flow, reduced cooling capacity, or visible leaks. Leakage rate should be ≤0.01 mL/min at 1.5 times operating pressure. If you observe these, inspect for fouling, blockages, or material degradation. Always follow the manufacturer's maintenance guidelines.
