Embodiment 1

[0041] see Figure 4 ~ Figure 6 , Figure 9 As shown, this embodiment provides a fixed pressure block for a single-tube IGBT, which is used to install and fix the single-tube IGBT1 on the radiator 3, including a fixing part 42 for connecting the radiator 3 and a fixing part 42 for fixing the single-tube IGBT1. The installation part 41, the installation part 41 and the fixing part 42 are respectively formed on the two ends of the fixed pressure block, the installation part 41 has a first surface and a second surface opposite, and the first surface is provided with a second An accommodating groove 411, one end of the first accommodating groove 411 facing the first surface is open, one end of the first accommodating groove 411 close to the fixing portion 42 is closed, and the first accommodating groove 411 is away from One end of the fixing portion 42 is open, that is, the end away from the fixing portion 42 extends and penetrates to the side wall of the mounting portion 41, and...

Embodiment 2

[0058] see Figure 7 As shown, this embodiment provides a combination of fixed briquetting blocks for a single-tube IGBT, including a plurality of fixed briquetting blocks 4 as described in Embodiment 1, the plurality of fixed briquetting blocks 4 are arranged side by side, and adjacent A bendable and breakable connecting piece 5 is provided between the sides of the fixed pressing block 4 .

[0059] Since single-tube IGBTs usually appear in groups, setting the fixed pressing blocks 4 in groups is beneficial to improve assembly efficiency. At the same time, the connecting piece 5 connecting the fixed pressing blocks 4 on both sides is set as a bendable and fractured structure, which can When a single or partial fixed pressing block 4 is required, the fixing pressing blocks 4 are separated from each other by breaking off the connecting piece 5, which is convenient for storage and automatic installation.

[0060] In this embodiment, the combination of the fixed pressing blocks 4...

Embodiment 3

[0063] see Figure 9 ~ Figure 12 As shown, this embodiment provides a power converter, including a heat sink 3, a single-tube IGBT and a fixed pressing block 4 as described in Embodiment 1.

[0064] The fixed portion 42 of the fixed pressing block 4 is connected to the radiator 3, the single-tube IGBT1 is provided with a positioning hole, the single-tube IGBT1 is accommodated in the first accommodation groove 411, and the first The positioning post 413 is plugged into the positioning hole on the single-tube IGBT1.

[0065] The radiator 3 is an aluminum radiator 3 .

[0066] The single-tube IGBT1 includes a stepped single-tube IGBT1a and a planar single-tube IGBT1b.

[0067] When installing the stepped single-tube IGBT1a, the first accommodating groove 411 and the first fixing groove 421 of the fixed pressure block 4 face the heat sink 3, and the second accommodating groove 415 and the second fixing groove 425 Facing the direction away from the heat sink 3, the stepped singl...

Abstract

In order to overcome the problem that the existing single-tube IGBT fixing method cannot realize precise positioning, has safety risk and takes up a large space, the invention provides a single-tube IGBT fixing pressure block. The single-tube IGBT fixing pressure block comprises a fixing part used for connecting a radiator and a mounting part used for fixing a single-tube IGBT. The mounting part and the fixing part are respectively formed at the two ends of the fixing pressure block. The mounting part has a first surface and a second surface which are opposite to each other. The first surface is provided with a first accommodating slot, the end of the first accommodating slot close to the fixing part is closed, the end of the first accommodating slot away from the fixing part is open, and a first positioning column extending to the first surface is arranged inside the first accommodating slot. Meanwhile, the invention discloses a single-tube IGBT fixing pressure block combination and a power frequency converter. The fixing pressure block provided by the invention has a simple structure, can be used to position a single-tube IGBT effectively, and has strong electrical protection property and good compatibility.

Description

technical field [0001] The invention belongs to the technical field of inverter crystal transistor installation structures, and in particular relates to a fixed pressing block for a single-tube IGBT, a combination and a power inverter. Background technique [0002] In the inverter industry, the function of the inverter part of the low-power inverter is mainly realized by IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor). At present, there are two packaging methods for IGBT devices: single-tube method and module method. With the development of the industry, the price competition of inverters has become increasingly fierce, and single-tube IGBTs have been used more and more because of their cost advantages. [0003] In practical applications, the single-tube IGBT will generate a lot of heat during operation, which needs to be dissipated by a radiator. Therefore, the single-tube IGBT needs to be placed close to the radiator to achieve the best heat di...
