Air Cooling Heatsink for Disc type thyristor & rectifier diode

Air Cooling Heatsinks for single- and double-sided cooling disc type power SCR thyristors and rectifier diodes during their operation.

Heatsinks are used for semiconductor devices for currents from 100A to 6300A and voltages VDRM/VRRM up to 7000V.

Heatsinks are used for disc (tablet type) semiconductors with сontact surface diameter from Ø19 mm to Ø100 mm.

Features: natural air cooling and forced air cooling; corrosion-resistant aluminum alloy; low thermal resistance; easy installation with a mounting slot; can be either standard models can also be customizing.

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.

Current range of disc type SCR thyristors and rectifier diodes for which air heat sinks (coolers, radiators) are used: 100A, 150A, 160A, 200A, 250A, 300A, 320A, 400A, 500A, 600A, 630A, 800A, 1000A, 1250A, 1500A, 1600A, 2000A, 2500A, 3000A, 3200A, 4000A, 5000A, 6000A, 6300A.

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 tabular 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.

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).

Specifications and parameters, dimensions, 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.

Recommendations for assembling a disc thyristor with an air heatsink:

Assembling disc thyristor with a heatsink

The reliability of heat transfer and electrical contact between the mating surfaces of the thyristor and the cooler over the entire temperature range is ensured by mounting torque (clamping force).

Before assembly you should perform visual inspection (1) contact surfaces for mechanical damages and wipe (2), soaked with alcohol (toluene, gasoline, acetone).

After inspection, fix the current contacts (leads), install a pin to fix the alignment of the structure.

To improve the parameters of heat transfer it is recommended to lubricate (3) a thin layer of silicone thermal conductive paste before the assembly (this is a recommendation and is not a prerequisite for installation).

Install the thyristor (3), the second part of the cooler, the fiberglass insulator and the thrust washer.

To thread the traverse (4) and evenly tighten the nuts. Make sure no misalignment and evenness of the contact surfaces.

When the parts are sufficiently clamped but moveable, we recommend placing the cooler on a flat surface and checking the tolerance for parallelism of the overall adjacent plane of the surfaces (5).

Clamp each nut in turn (about a quarter turn) to the stop (6). The amount of deflection of the traverse determines whether the achieved clamping force corresponds to the required one.

After installation, the fasteners (nuts and washers) must be additionally secured against corrosion.



Tips and recommendations for power thyristors:

The power thyristors should not be operated for long periods of time at their limit load for all parameters. In this case, the safety factor is determined by the required degree of reliability of the device.

Replace a failed power thyristor with a thyristor that matches the parameters of the one being replaced.

Supercooling must be provided when operating in an environment with an elevated ambient temperature.

Periodic cleaning of power thyristors and coolers to remove dust and contaminants is recommended to ensure proper heat dissipation.

Inductive current dividers (often twisted toroidal wire) should be used to equalize currents between power thyristors connected in parallel. The most popular connection methods are closed circuit, common coil circuit, or power thyristor. The efficiency of current dividers in this case is determined by the cross section of the magnetic wire.

Prevention of voltage unbalance when power thyristors are connected in series is achieved by using shunt resistors connected in parallel with each thyristor. Voltage equalization in transient conditions is provided by connecting capacitors in parallel to each thyristor.

Device under voltage

It is strictly forbidden to touch power thyristors under high voltage during operation.

I'm Gizem, I'm a chemical engineer. I'm interested in making ceramic stuffs as a hobby. Would you please give some explanation about my questions below;
1) If I only mix SiO2 and Fe2O3 (3:1), can i get a suitable product without using other components?
2) Can i use water as fastener? or would you suggest me another fastener?
3) At which temperature should i mix them?
Thank you for your interest, Kind Regards

Hello, Gizem. The mass of ceramic is produced by grinding and mixing with water of different components: clay, feldspar, sand, kaolin. The proportions of these materials are different percentages, depending on what and with what characteristics you need to get a ceramic mass.
Each manufacturer of ceramic mass has its own recipes and its own raw materials, which are available in its region.
There are also books on ceramics that specify the chemical composition and approximate recipes for ceramic masses.

Is It need to apply vaselin or thermal past at Thyristor surfaces then attach to radiator/current leading parts?

When assembling thyristors, diodes with heat sinks, it is recommended to lubricate the contact surfaces with a thin layer of heat conducting paste to improve the heat transfer parameters. But this is not a prerequisite for assembly.
