Heatsink contact surface diameter Ø100 mm Applied device housing сontact surface Ø80 – Ø100 mm outside diameter Ø120 – Ø150 mm Applies to devices for current 1600A – 6300A Power dissipation 650 W Heatsink O193 on request +– Dimensions B×L×H 385×300×305 mm Weight 28 kg Air Cooling Heatsinks O193-300 JY FACTORY are used for single- and double-sided cooling of power semiconductor devices in disc design, with housing type PD83, PD93, PT83, PT93, PT94, PTT94, PTO95, D.G1, T.H1, T.G5. The power dissipation of the cooler with natural cooling is 650 W. Heatsink contact surface diameter is Ø100 mm.

Applied device housing: сontact surface Ø80-Ø100 mm, outside diameter Ø120-Ø150 mm. Heatsink is used for cooling of high power SCR thyristors and rectifier diodes for currents 1600A – 6300A. Airflow cooling can be natural or forced, depending on the amount of heat generated and the operating conditions of the semiconductors. Features: corrosion-resistant aluminum alloy; low thermal resistance; easy installation with a mounting slot; can be either standard models can also be customizing.

Heat sinks are made of aluminum radiator profiles and do not require additional protective coating when used in different climatic conditions. Assembly of semiconductor devices (power diodes, thyristors) of tablet (disk) design with coolers is done by clamping bolts and traverse. The contact surfaces of the heatsink and power device must have low roughness and flatness deviations. For minimum electrical losses and maximum heat dissipation of the devices, the appropriate mounting force Fm specified in the power device specifications must be observed.

Before mounting the contact surfaces of the heatsink, current contact and semiconductor device should be wiped with a cloth soaked in alcohol (toluene, benzene, acetone) and it is recommended to lubricate with a thin layer of silicone-organic heat transfer paste (this is a recommendation and is not a prerequisite for installation). Current range of disc type SCR thyristors and rectifier diodes for which air heat sinks (coolers, radiators) are used: 1600A, 1700A, 1800A, 1900A, 2000A, 2100A, 2500A, 2600A, 2700A, 2800A, 3000A, 3200A, 4000A, 4200A, 4300A, 5000A, 5200A, 5700A, 6000A, 6300A. Specifications and parameters, dimensions, outlines and drawings of air-cooled heat sink (radiator) are listed below.

Our company provides a quality guarantee for air cooling heatsink of 2 years from the date of purchase. When supplying heatsinks, if necessary, we provide technical passport.

The final price of air cooling heatsink depends on the quantity, delivery terms, manufacturer, country of origin and form of payment.
