Abstract
The invention provides a fixing method of a bolt-type aluminum electrolytic capacitor core package with good heat dispersion, characterized by comprising the following steps of: 1. respectively drilling a bottom centre hole and a top centre hole on the bottom part and top part of the core package, arranging a bottom thimble on the bottom part of an aluminum shell, putting the core package in the aluminum shell, and pressing and fixing the core package, and aligning the bottom centre hole of the core package to the bottom thimble during the process; 2. arranging a cover plate thimble on a cover plate, aligning the cover plate thimble to the top centre hole of the core package, inserting the cover plate thimble in the top centre hole and pressing the same while mounting the cover plate, and then, covering a sealing ring on the cover plate to seal the opening, and adding no fixing glue during the process. The fixing method of the invention has the advantages of very uniform heat dispersion and non local heat accumulation phenomenon; meanwhile, no fixing glue exists between the core package and the aluminum foil to block the heat dispersion, so that the heat generated during the working process of the core package can be dissipated without any blockage, which greatly improves the heat dispersion of the products and stabilizes the performance of the products.
Description
Technical field
The present invention relates to a kind of screw bolt-type aluminium electrolytic capacitor core cladding fixing method of good heat dispersion performance, belong to the aluminium electrolytic capacitor technical field.
Background technology
The screw bolt-type aluminium electrolytic capacitor generally is applied to equipment such as various power supplys, frequency converter, electric welding machine, wind power generation, and purposes is very extensive, but very high for the requirement of heat dispersion, and product heat dispersion missionary society produces serious negative effect to life of product.
Traditional screw bolt-type aluminium electrolytic capacitor core cladding fixing method comprises the core bag is placed in the aluminum hull and with solid gum the core bag is fixed in the aluminum hull then.In order to reach fixed effect; Generally need solid gum be added to 1/3rd places of core bag height; Because the own capacity of heat transmission of solid-state glue that the fixed core bag adopts is poor, core encapsulates this solid-state glue and is enclosed in the centre, and serious obstruction is received in the heat radiation of core bag itself; Cause heat accumulation, life of product seriously shortens.
Summary of the invention
The screw bolt-type aluminium electrolytic capacitor core cladding fixing method that the purpose of this invention is to provide a kind of good heat dispersion performance.
In order to achieve the above object, the invention provides a kind of screw bolt-type aluminium electrolytic capacitor core cladding fixing method of good heat dispersion performance, it is characterized in that, comprising:
Step 1: bottom and top at the core bag are opened bottom centre hole and top center hole respectively, and the bottom thimble is set in the bottom of aluminum hull, and the core bag is put into aluminum hull and is fixed, and in this process, the bottom thimble of aluminum hull will be aimed in the bottom centre hole of core bag;
Step 2, on the cover board the cover plate thimble is set, behind the top center hole with cover plate thimble aligned with core bag, when cover plate is installed, inserts the cover plate thimble in the top center hole and compress, on the cover board add sealing ring subsequently and seal, do not add any fixing glue in this process.
Preferably, described bottom thimble stretches into the hole 10mm of bottom centre of core bag.
Preferably, the diameter of described bottom thimble is than the little 1mm～1.5mm of core winding pin diameter.
Preferably, described cover plate thimble length stretches into the top center hole 5mm～10mm of core bag.
Among the present invention, because the fixation of thimble up and down, so the core bag occupy the aluminum hull center; The core bag is consistent with aluminum hull distance all around, so heat radiation is very even, and the phenomenon that does not exist amount of localized heat to assemble; Simultaneously, no fixing glue hinders heat radiation between core bag and the aluminium foil, and the heat that the core job contract produces when doing can unhinderedly distribute; Improve the product heat-sinking capability greatly, properties of product are stablized.
