Description

Radiator, PCB board and power tube combination structure convenient to installation Technical Field The utility model relates to a radiator, a PCB and a power tube combination structure, in particular to a radiator, a PCB and a power tube combination structure which are convenient to install. Background As a core element of an electronic power technology, a power tube is widely used in various hot fields such as an industrial power supply, an electric automobile, energy storage and the like. Because of its small size and high heat generation, it is often necessary to dissipate heat by mounting it on a radiator. The common radiator mainly comprises a section radiator, an mechanically-added radiator, an open-mold radiator and the like, but is affected by the packaging of the power tube, and when the power tube is welded perpendicular to the PCB, the common installation mode is from bottom to top or from top to bottom. As shown in a diagram a of fig. 1, when the radiator body 3 is installed from bottom to top, equipment or components need to be turned over during disassembly and assembly, so that the fasteners 5 can be installed from the installation substrate 2 to the PCB body, and are affected by the assembly sequence. As shown in b of fig. 1, the radiator body 3 can avoid problems of overturning, assembling sequence, influencing layout and the like caused by a bottom-up mounting mode when the top-down mounting mode is adopted. But this structure needs to be in PCB board body 1 corresponding fastener 5 position trompil to make things convenient for fastener 5 installation, and need put into the mounting hole with fastener 5 and lead to the aperture great, influence PCB board overall arrangement and intensity. The fastener 5 is not easy to send into the mounting hole during mounting, the fastener 5 is easy to fall off when the magnetic screwdriver (mounting tool 01) is used for adsorbing the fastener 5, and the fastener 5 is difficult to take out after falling off, for example, when the austenitic stainless steel fastener (mounting tool 01) is used, the weak magnetism of the fastener causes that the screwdriver cannot adsorb, the mounting difficulty is extremely high, and the assembly efficiency is seriously affected.
