Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] In the thyristor 1 connected in series, the heat pipe radiator and the thyristor are connected in series and crimped at intervals, which is characterized in that the overall structure is compact, and the attached high-voltage insulating crimping parts include: high-purity epoxy insulating plate 5, aluminum alloy at the end Metal block 6, insulating casting with insulating umbrella group fixed on the heat pipe radiator 2, top pressure mechanism 4, insulating partition 7 between the two heat pipe radiators 2, the above structure ensures that different types of thyristors are suitable for series crimping The crimping force and crimping concentricity reduce the contact thermal resistance between the thyristor and the heat pipe radiator substrate 8 to a lower level, and at the same time ensure that the overall high insulation characteristics of the h...

Abstract

The invention relates to a high pressure and high power series thyristor self-cold and hot pipe radiator unit; a hot pipe radiator is connected with a thyristor in series as well as in press connection with the thyristor in sequence; the upper and the lower parts of the hot pipe radiator are fixed by high pressure resistant epoxy insulation boards; an end aluminium alloy metal block, an ejector screw rod and a laminated spring are used for leading a thyristor valve to be pressed and connected in series with proper force; meanwhile, high voltage distribution and insulation property are considered in a whole, so that the insulation problem caused in the process that the high pressure thyristor is closely connected and pressed with the hot pipe radiator in series can be solved. The invention has the advantages of compact structure, high heat dissipation efficiency, high pressure resistance, no need of maintenance, convenient combination, integral modularized assembly, etc.

Description

technical field [0001] The invention relates to the fields of power semiconductor devices, power electronics, heat transfer and heat dissipation, and in particular to a connection method of high-voltage and high-power serial thyristor self-cooling and heat pipe radiator groups. Background technique [0002] At present, the application of high-voltage and large-capacity power conversion technology in the field of power electronics technology is becoming more and more extensive. The line voltage is high and the withstand voltage of power electronic components is relatively low. Thyristor valve power handling capacity requirements. Valve devices composed of thyristors in series are widely used in static var compensation, high-power DC power supply, and high-voltage frequency conversion speed regulation. The heat dissipation of its components mainly adopts water cooling system and heat pipe radiator. [0003] The heat pipe radiator has high heat conduction capacity, and can tra...
