Pressure resisting airtight cold plate vacuum brazing universal tool

Abstract

The invention relates to a pressure resisting airtight cold plate vacuum brazing universal tool. The universal tool comprises a mother-son plate and a base plate with the back face provided with square grooves, wherein the mother-son plate is provided with square grooves arranged in a matrix manner. A cold plate is placed on the front face of the base plate, the mother-son plate is located on theother face of the cold plate, and the universal tool is used for pressing the cold plate by pressing the mother-son plate. The device can provide enough pressure in the pressure resisting airtight cold plate welding process, effective pressurizing is achieved, component deformation is corrected, and the welding gap and welding deformation of the cold plate are controlled; the welding quality, an inner runner and boundary dimension precision of the cold plate are guaranteed; and the base plate, the mother-son plate and the other components are provided with square groove structures, radiation heat absorbing and heat releasing of products in a vacuum braking furnace are facilitated, and the brazing efficiency is improved.

Description

technical field [0001] The invention designs a welding tool for vacuum brazing, in particular a universal tool for vacuum brazing of a pressure-resistant airtight cold plate. Background technique [0002] With the gradual miniaturization and integration of radar and other electronic equipment, the integration of various components is getting higher and higher, and the packaging density is increasing, resulting in a sharp increase in the heat flux of electronic equipment. The traditional air-cooling technology can no longer meet the heat dissipation requirements of high heat flux devices. More efficient liquid cooling technology is needed. The key component of liquid cooling technology is the cold plate. [0003] The cold plate is usually machined first and then welded and formed by vacuum brazing. When vacuum brazing is used for welding, the welding quality of the cold plate directly affects the performance of the cold plate, and the welding tool is an important factor affe...
