Water-cooled heat sink

Outstanding cooling effect!

Due to the increase in the capacity of components, air cooling methods are reaching their limits. Our oxygen-free copper water-cooled heat sinks, with a thickness of 6 to 20 mm, are about one-tenth the size of air cooling!! They provide several times the cooling effect per unit area and contribute to space-saving.

【Comparison data available!】WELCON's water-cooled heat sink brochure

A must-see for those struggling with heat generation! Introducing uniform cooling and low refrigerant heat sinks.

Due to the increase in computational load and high output, the heat generated by chips and light sources has increased, and we often hear the following concerns: - Air cooling cannot sufficiently cool the high heat generation. - I want to try water cooling, but I wonder if it will leak. - Considering carbon neutrality, I want a cooling method that reduces environmental impact and power consumption. Therefore, we are releasing a brochure on heat sinks as a reference for considering water cooling! Please feel free to download the brochure.

Aluminum Water-Cooled Heat Sink "YC Series"

Due to being shaped with aluminum profiles, it achieves a cost reduction of 30-40% compared to copper! This is a water-cooled heat sink that uses forced cooling with water.

Semiconductor devices (transistors, CPUs, IGBTs, etc.) used in electrical and electronic equipment can be destroyed by the heat generated during operation if cooling is not performed. A heat sink is an electronic component radiator that prevents the destruction of the device by quickly transferring and cooling this heat. Cooling methods are classified into natural cooling, which utilizes the convection of air generated by the heat produced, and forced cooling, which involves using a fan to force air circulation or using cooling media such as water. This product uses water for forced cooling and is a water-cooled heat sink that achieves simplicity and low cost by using aluminum profiles and copper pipes. 【Features】 ■ Formed from profiles (custom options and pipe embedding specifications are also possible) ■ Low cost ■ Specification confirmation can be handled with simulation software → If you provide the loss power (W) and the model name of the FAN to be used, we can present it in a graph, which can be used as evidence when conducting prototypes. *If you wish to request a simulation, please contact us via the inquiry button. *Online meetings are also possible, so feel free to reach out to us.

Water-Cooled Heat Sink Series

Flow path design to achieve uniform cooling

Water is circulated inside a metal plate to cool the entire plate, and a heating element is attached to absorb heat. This is primarily used for cooling semiconductor devices such as IGBTs, as well as for various applications and industries including UV-LEDs, amplifiers, and Peltier elements. The performance of water-cooled heat sinks varies significantly depending on the flow path structure and the machining precision of the element surface. Our company is committed to efficient and uniform cooling within the plane, and we design and manufacture water-cooled heat sinks that meet your desired performance and shape.
