Embodiment Construction
[0030] The present invention provides an IGBT box and its assembly method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] like figure 1 As shown, the present invention provides an IGBT box, including a bottom plate 100, a side plate 200 integrally formed or connected to the bottom plate 100, and a receiving cavity surrounded by the two (because the label is easily confused with the mark on the bottom plate 100, and the text description It is enough to reflect its structure, so it is not marked), there is a cover plate 300 above the storage cavity, and the cover plate 300 is connected to the upper end surface of the side plate 200; several c...

The invention discloses an IGBT box body and an assembling method thereof. According to the IGBT box body, an upper end surface of a base plate is connected with a plurality of connection columns, one ends of the connection columns, opposite to the base plate, are connected with a liquid cooling plate, and an upper end surface of the liquid cooling plate is provided with an IGBT module. According to the IGBT box body, the liquid cooling plate, the IGBT module, and related devices thereof are separated from the base plate so that the heat radiation effect of the IGBT module and the related devices thereof is enhanced, and the adjustment space is increased; during the IGBT device test, the whole IGBT does not need to be dismounted, and only the device with faults is directly dismounted; and the heat radiation effect is enhanced, and the adjustment space is increased so that the damage to the devices due to insufficient heat radiation caused by over-short distance between the devices is avoided, and the arrangement space and the overall dimension are reduced.
Description
technical field [0001] The invention relates to an IGBT box body and an assembly method thereof, in particular to a split-structure IGBT box body and an assembly method thereof. Background technique [0002] As one of the important high-power mainstream devices of power electronics, IGBT has been widely used in household appliances, transportation, power engineering, renewable energy and smart grid; in industry, it is used in traffic control, power conversion, industrial motors, etc. , uninterruptible power supply, wind power and solar energy equipment, and frequency converters for automatic control. [0003] In many fields, because it involves protecting the use effect and life of IGBT and other heating devices, it is necessary to dissipate heat. Traditional air cooling is difficult to exert its effect on medium and high-power IGBTs, making IGBTs unable to work in a stable state. Thus affecting the service life and performance. [0004] Most of the existing combined boxes...
