Product details: Model ZLT-GTR:
To determine the fire resistance by the fire hazard test, accordance with IEC60695-2-10(2013), IEC60335, IEC60598 and other standards.
The ignition source is imitated by an electrically heated wire loop against which the sample is pressed with a constant force. A miniature jacket thermocouple serves as a sensor for the loop temperature.
The sample has to be fastened to a carriage on which, by means of a tensioning cord, a weight with a force of 0.95N is effective in the direction of the wire loop. Scales enable the reading of the flame height and the depth of penetration. Approx 200 mm below the wire loop a board of pine wood, covered with a layer of tissue paper, is mounted.
This device enables to judge the danger of a fire spreading through burning drops or glowing parts falling from the sample. The calibration is done with silver foil, when the foil melts, the measuring unit must indicate a temperature of 960 ° C.
Standard outfit:
1 wire loop of nickel-chromium, Φ 4 mm, accordance with IEC60695-2-10 figure 1, with clamping mechanism, with Φ 1.05 mm for the thermocouple,
1 carriage with fixture for the specimen, with a rate of approach and withdrawal of 10 mm/s to 25mm/s,
1 fine rope pull mechanism with weights for loads of 0.95± 0.2N,
1 gauge of 7 mm for the depth of penetration, with maximum pointer and stop,
1 scale to measure the flame height,
1 high current isolating transformer to heat the wire loop, with series connected variable ratio transformer, to set the temperature up to 960± 15 ° C,
1 type K thermocouple Chromel-alumel, Φ 1.0 mm, length approx. 500 mm, to indicate the temperature of the glow-wire loop, with digital display measuring range 0~1050 ° C, built-in operable,
1 chamber with a volume of at least 0, 5 mm3, black interior,
1 wooden board, 10 mm thick, 10 sheets of wrapping tissue, of grammage between 12g/~30g/.
Power supply: 220V50Hz other voltages request.
IGBT Heat Sink
An IGBT (Insulated Gate Bipolar Transistor) heat sink is a device used to dissipate heat generated by an IGBT. IGBTs are commonly used in high-power applications such as motor control, power inverters, and welding equipment, where they can generate significant amounts of heat. The Aluminum Heat Sink is designed to provide a large surface area to dissipate the heat, thereby reducing the temperature of the IGBT and preventing damage to the device.The IGBT heat sink is typically made of a material with high thermal conductivity, such as aluminum alloy or copper, and is designed to maximize the surface area available for heat dissipation. The aluminum heat sink is attached to the IGBT using a thermal interface material, such as thermal paste or a thermal pad, which helps to transfer the heat from the IGBT to the heat sink.The design of the IGBT heat sink is critical to its effectiveness. The size and shape of the fins, as well as the spacing between them, can significantly impact the heat dissipation capacity of the heat sink. The aluminum heat sink must also be designed to fit the specific IGBT package and application requirements, as different IGBTs generate different amounts of heat and require different cooling solutions.
In summary, an IGBT heat sink is an essential component in high-power applications that use IGBTs. It helps to dissipate the heat generated by the IGBT, thereby preventing damage to the device and ensuring reliable operation. The design of the heat sink is critical to its effectiveness, and it must be carefully matched to the specific IGBT and application requirements.
