Embodiment Construction

[0020] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] Such as figure 1 Embodiment 1 of a welding device for a flat-plate heat collector shown in the present invention, wherein the metal flow channel in the flat-plate heat collector has a semicircular structure, and the welding device has a left electrode roller 5, an insulator 6 and The right electrode roller 7 is provided with an annular groove matching the arc-shaped surface of the metal flow channel on the insulator 6 .

[0022] The left electrode roller 5, the insulator 6 and the right electrode roller 7 are connected as a whole, or the left electrode roller 5 and the right electrode roller 7 can freely rotate 360° around the insulator 6 to produce c...

Abstract

The invention relates to a welding device for a flat plate collector and a user method of the welding device, wherein a metal runner in the flat plate collector is of a semi-circular structure; the welding device comprises a left electrode roller, an insulator and a right electrode roller which are arranged sequentially; and an annular groove matching with the circular arc-shaped surface of the metal runner is arranged on the insulator. Based on the electric resistance welding principle, the close contact of metal bars and a heat absorption plate is realized by the compression of rollers; meanwhile, electric current flows through the electrodes at two sides of the rollers to form an inductive effect, so that the welding fixation between the metal bars and the heat absorption plate is realized; the welding between the metal bars and the heat absorption plate has strength requirement and no sealing requirement, so that the rollers do not have higher requirements on moving speed and pressure strength; the manual welding can be carried out completely by using a handle, so that the cost of the present ultrasonic and laser welding equipment is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a welding device for flat plate heat collectors and a method for using the same. Background technique [0002] In the known technical field, the heat-absorbing element of a flat-panel solar collector is a metal heat-absorbing plate (generally copper or aluminum), and the surface of the heat-absorbing plate is a solar selective absorption coating; The heater is mainly composed of a heat absorbing plate and a medium flow channel welded, a metal frame and a back insulation material, and the upper part is glass with high light transmittance. [0003] There are generally two welding methods for the welding of the heat absorbing plate and the metal flow channel in the flat collector: ultrasonic and laser. A defect of ultrasonic welding is that it will destroy the film layer of the heat absorbing plate and affect the heat collection efficiency. Laser welding has the problems o...
