Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0024] see figure 1 and figure 2 As shown, according to an embodiment of the present invention, a fixing device for a switch tube is provided. The fixing device includes a body part 10, and the body part 10 is respectively connected to a PCB board 20 and a heat sink 30; the body part 10 is provided with at least one fixing device. Groove 11 , the fixing groove 11 is used for installing and fixing the switch tube 40 . The switch tube can be an IGBT or a MOS tube, and the switch tube 40 is directly installed and fixed in the fixing groove 11 .

[0025] Place the switching tube (such as IGBT device) in the fixing groove 11 on the fixing device, and indirectly compress the switching tube (such as IGBT device) through the fixing device, so that the switching tube (such as IGBT device) is...

Abstract

The invention discloses a switch tube fixing device and a switch tube assembly. The switch tube fixing device comprises a body part which is connected with a PCB and a radiator, wherein at least one fixing groove is formed in the body part and used for installing and fixing a switch tube. The switch tube fixing device and the switch tube assembly effectively solve the problems that a direct screwfixing mode for the switch tube in the prior art is small in heat dissipation area, the risk that the switch tube is damaged exists and general assembly cannot be achieved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a fixing device for a switch tube and a switch tube assembly. Background technique [0002] With the development of basic science such as material science, electronic information technology and packaging technology, switching tubes (such as IGBT devices or MOS tubes) are gradually replaced by discrete switching tubes (such as IGBT devices) due to price, performance and other reasons. . In the fields of switching power supplies and photovoltaic inverters, switching tubes (such as discrete IGBT devices) have been widely used. However, in practical applications, the installation and fixation of the switch tube (such as the IGBT device) affects the performance and reliability of the switch tube (such as the IGBT device), and further affects the quality of the product. For some high-power occasions, the natural heat dissipation and radiation heat dissipation of the switch tub...
