Embodiment Construction

[0024]The present invention will be further described below in conjunction with embodiments, but it is not limited to the content of the description.

[0025]Such asfigure 1 withfigure 2 As shown, the present invention discloses a mounting structure for a switch tube, including a heat sink 10 and a PCB board 20. The PCB board 20 is relatively movably connected to the heat sink 10 through a connector, the heat sink 10 and the PCB board 20 Between them is used to install the switch tube 60; the PCB board 20 is movable relative to the switch tube 60. In the mounting structure for the switch tube of the present invention, since the PCB board 20 is relatively movably connected to the radiator 10 through the connector, the distance between it and the radiator 10 can be adjusted by moving the PCB board 20, because the switch tube 60 Set on the heat sink 10, therefore, the PCB board 20 is moving while adjusting the distance between the PCB board 20 and the switch tube 60, so as to prevent the ...

Abstract

The invention discloses a mounting structure for a switch tube and an air conditioner. The structure comprises: a radiator; and a PCB which is connected to the radiator in a relatively movable mode through a connecting piece, wherein a switch tube is installed between the radiator and the PCB, and the PCB can move relative to the switch tube. According to the mounting structure for the switch tube, the PCB is connected to the radiator in a relatively movable manner through the connecting piece, so that the distance between the PCB and the radiator can be adjusted by moving the PCB, and the switch tube is arranged on the radiator, so that the distance between the PCB and the switch tube is adjusted while the PCB moves, and the mounting structure for the switch tube is convenient to mount and dismount. Therefore, the distance between the PCB and the metal element on the switch tube is prevented from being too short, the creepage distance can be effectively ensured, and the overall reliability is improved.

Description

Technical field[0001]The invention relates to the technical field of air conditioners, in particular to an installation structure for switch tubes and an air conditioner.Background technique[0002]As a commonly used power device, IGBT is widely used in products such as power supplies, household appliances and air conditioners, and plays a key role. With the development of device materials and packaging technology, discrete IGBTs are gradually replacing IGBT modules to meet the market's design requirements for low-cost and miniaturized products. In practical applications, the installation of IGBTs is also related to the performance and reliability of IGBTs, which in turn affects the quality of products.[0003]In order to ensure that the IGBT works in a suitable temperature range, in some higher power application scenarios, natural heat dissipation can no longer meet the heat dissipation requirements, and it is often necessary to install a larger heat sink for the IGBT for auxiliary hea...
