Small multi-assembly brazing clamping device

Abstract

Provided is a small multi-assembly brazing clamping device. The small multi-assembly brazing clamping device comprises cores, wherein an upper supporting board is installed on a cover board at the tops of the cores, a lower supporting board is installed on a cover board at the bottoms of the cores, an upper base board is installed at the top of the upper supporting board, a lower base board is installed at the bottom of the lower supporting board, the two sides of the upper base board and the two sides of the lower base board are respectively provided with a plurality of through holes, and screws are installed in the through holes and are perpendicular to the upper base board and the lower base board respectively; the head portions of the screws are fixed on the top of the upper base board through first nuts, the bottoms of the screws are fixed at the upper end of the lower base board through second nuts, and the bottoms of the screws are fixed at the lower end of the lower base board through third nuts. The cores are installed between the upper base board and the lower base board, and the screws which are perpendicular to the cores are installed, so that the phenomenon of dislocation of the cores when thermal expansion stress occurs in the brazing process is prevented; the head portions and the root portions of the screws are respectively fixed on the base boards through the nuts, so that the structure is firm, the shifting phenomenon does not happen, the perpendicularity of the cores is guaranteed, and accordingly the brazing quality of the cores is ensured.

Description

technical field [0001] The invention relates to the technical field of heat exchanger auxiliary equipment, in particular to a small-sized multi-unit brazing clamping device. Background technique [0002] A heat exchanger (also known as a heat exchanger) is a device that transfers heat from one heat-carrying medium to another heat-carrying medium. In industrial production processes, heating or cooling is often required, that is, heat transfer. When one fluid exchanges heat with another fluid and does not allow mixing, it is required to be carried out in a partition heat exchanger, which is used in chemical, petroleum, power, food and other industries. The main function of the heat exchanger is cold and hot Heat energy exchange between fluids. [0003] During the processing of the heat exchanger core, brazing is usually used, and the core is installed on the bracket. The bracket in the prior art has no reliable fixing device. Due to the different sizes and quantities of the ...

Problems solved by technology

[0003] During the processing of the heat exchanger core, brazing is usually used, and the core is installed on the bracket. The bracket in the prior art has no reliable fixing device. Due to the different sizes and quantities of the cores, the clamping is unstable. The core is prone to misalignment or collapse and deformation, which seriously affects the brazing quality of the core and increases the cost
