Welding tool for gas collection assembly of heat exchanger and welding tool device

Abstract

The invention relates to the technical field of welding tools, in particular to a welding tool for a gas collection assembly of a heat exchanger and a welding tool device. Specifically, the heat exchanger includes the gas collection assembly including a gas collection main pipe and a plurality of gas collection branch pipes, wherein the gas collection main pipe is provided with a plurality of communication structures; the welding tool comprises a base body, a first fixing mechanism and second fixing mechanisms, and the first fixing mechanism and the second fixing mechanisms are arranged on thebase body; and in a state of getting ready for welding, the gas collection main pipe is fixed by the first fixing mechanism, the first ends of the gas collection branch pipes are in butt joint with corresponding communication structures in a matched manner, and the gas collection branch pipes are fixed through the second fixing mechanisms. By means of the welding tool, the gas collection main pipe and the gas collection branch pipes are simultaneously fixed through the first fixing mechanism and the second fixing mechanisms, and the problem about welding deformation of the gas collection mainpipe and the gas collection branch pipes is effectively solved.

Description

technical field [0001] The invention relates to the field of welding tool technology, in particular to a welding tool and a welding tool device for a gas collecting component of a heat exchanger. Background technique [0002] The indoor or outdoor units of existing air conditioners mostly use copper tube fin heat exchangers (hereinafter referred to as heat exchangers), such as figure 1 As shown, the heat exchanger includes a gas collection assembly 1 and a liquid collection assembly 2. The gas collection assembly 1 and the liquid collection assembly 2 are connected together through the hairpin tube inside the heat exchanger. The inside of the liquid collection assembly 2 flows liquid, and the gas collection assembly 1 The gas circulates inside, and the refrigerant enters and exits the heat exchanger through the gas collection assembly 1 and the liquid collection assembly 2. Such as figure 2 As shown, the gas collection assembly 1 generally includes a gas collection main p...
