Embodiment

[0029] Such as Figure 1-2 As shown, the present embodiment provides a power device, the heat sink 1 combined with the power device 2 performs heat dissipation, wherein, the heat sink 1 is formed with a raised structure 11 on the contact surface with the power device 2, even if the heat sink 1 The heat dissipation surface protrudes upwards to form a mounting area for the power device 2 , and a power device mounting surface for mounting the power device 2 is formed on the mounting area formed by the raised structure 11 . Specifically, the non-metallic mounting surface formed on the upper surface of the power device 2, when the power device 2 is assembled to the radiator 1, the non-metallic mounting surface of the power device 2 and the power device mounting surface on the raised structure 11 are matched to complete the installation, wherein , the range of the height L1 of the raised structure 11 is 1.5mm-2.5mm, further, the range of the height L1 of the raised structure 11 is p...

Abstract

The invention relates to a radiator for a power device and the power device. A convex structure and a groove are formed on a contact surface of the radiator and the power device, the power device is assembled on the convex structure, pins of the power device face the direction far away from the groove, so an electrical safety distance between the pins of the power device and the radiator is increased, safety problems of sparking and the like caused by small electrical safety distance of the power device are avoided, application reliability of the power device is improved, and the power deviceand the radiator operate stably.

Description

technical field [0001] The invention relates to a radiator and a power device, in particular to a radiator and a power device for a power device. Background technique [0002] Power devices are mainly used in frequency conversion inverters and other inverter circuits, and are the core components of energy conversion and transmission in the field of industrial control and automation. [0003] The temperature of this type of device is too high during operation, which is very easy to cause burnout. In order to ensure the reliability of the device, it will be assembled and contacted with the radiator in circuit application to ensure long-term reliable operation. The heat sink itself is not a part of the circuit, but if the mounting surface of the heat sink module is in contact with the surface of the power device, if the electrical clearance between the heat sink module and the metal pin is small, it will easily cause the failure of the power device, such as leakage or foreign m...
