40×80×12mm Aluminum Water Cooling Block is a compact liquid cooling heatsink designed for Peltier thermoelectric modules and custom thermal management systems. Its extended 40×80mm contact area makes it suitable for cooling setups using multiple 40×40mm Peltier modules or other applications requiring a larger liquid-cooled thermal surface.

Manufactured from aluminum with a 1mm wall thickness, this water block provides an efficient pathway for circulating water or coolant. It features two approximately 8mm hose connectors for convenient integration into a pump, reservoir, radiator, or other liquid cooling loop.

How It Works:

• The water block is mounted against the Peltier module or thermal surface.

• Thermal paste can be applied between the contact surfaces to improve heat transfer.

• Water or coolant enters through one hose connector.

• The liquid flows through the internal cooling channel and exits through the second connector.

• A pump and radiator can be added to create a complete liquid cooling loop.

• Depending on the system configuration, the block can help remove or transfer heat from the Peltier assembly.

Installation Instructions:

• Clean the Peltier module and water block contact surfaces.

• Apply a thin layer of thermal paste or suitable thermal interface material.

• Align the water block with the cooling surface.

• Secure the block evenly without applying excessive pressure.

• Connect suitable tubing to both approximately 8mm hose connectors.

• Check all hose connections for leaks.

• Test coolant circulation before powering the Peltier module.

Product Instructions:

• Use compatible tubing for the approximately 8mm connectors.

• Ensure sufficient coolant flow during operation.

• Check the complete system for leaks before electrical operation.

• Keep the cooling loop clean to maintain efficient heat transfer.

• Use suitable coolant according to the application.

• Do not operate a Peltier system without adequate thermal management.

• Ensure proper mechanical mounting to prevent damage to the Peltier module.
