Stretching arc-shaped pressure plate used for radiator

Abstract

The invention discloses a stretching arc-shaped pressure plate used for a radiator. The stretching arc-shaped pressure plate is characterized in that the arc shape of the stretching arc-shaped pressure plate is similar to the shape of a butterfly joint of a stretching heat conduction tube, the stretching heat conduction tube is controlled to have no deformation, and the stretching arc-shaped pressure plate comprises the stretching heat conduction tube, a communicating tube, a connecting piece, a water inlet, a water outlet, a deflation valve, an M-shaped depression bar and a plurality of stretching arc-shaped pressure plate bodies, and is welded to be rectangular or square. The two sides of the strip direction of a rectangular plate are downwards turned by 90 degrees, the middle part of the strip direction of the rectangular plate is subjected to downward stretch flanging to form an inner boss shape, the two straight ends of the middle section of each stretching arc-shaped pressure plate body are in an arc boss shape and are downwards stretched to form a slope at an angle of 30 degrees, the two ends are straight, the two ends in the direction of the rectangular plate are downwards turned by 90 degrees, the middle part of each stretching arc-shaped pressure plate is subjected to downward stretch flanging, two sides of a boss are semicircular, the shape of the rectangular plate after stretching is similar to the shape of the butterfly joint of the stretching heat conduction tube, and the stretching arc-shaped pressure plate bodies are crossly and uniformly distributed in a plurality of adjacent gap spaces which are fixedly connected and are communicated with the stretching heat conduction tube in series, so that a cooling fin is guaranteed to have internal pressure without expansion, the material is thin, the cost is reduced and the purposes of attractive appearance and practicability are achieved.

Description

technical field [0001] The invention relates to a water heating radiator with an auxiliary pressure plate, in particular to an indoor heating type water heating or steam heating as a heat source material is a thin-walled radiator, which belongs to an indoor heating device. Background technique [0002] There are many types of radiators, but they are made of stainless steel with thin walls, light weight, beautiful appearance, no rust, low cost and long service life. The selection of stainless steel, welding and making radiators conforms to the international trend and is the best choice for heating. A great progress in the radiator industry. Although stainless steel is used as a direction for radiator material selection, as experts say, material selection is the most important, and the second is to solve the quality of welding and how to prevent deformation. The patent applied by the inventor before 201420142408.8 Stretching to form a butterfly shape is to prevent excessive in...

[0002] There are many types of radiators, but they are made of stainless steel with thin walls, light weight, beautiful appearance, no rust, low cost and long service life. The selection of stainless steel, welding and making radiators conforms to the international trend and is the best choice for heating. A great progress in the radiator industry. Although stainless steel is used as a direction for radiator material selection, as experts say, material selection is the most important, and the second is to solve the quality of welding and how to prevent deformation. The patent applied by the inventor before 201420142408.8 Stretching to form a butterfly shape is to prevent excessive internal pressure and deformation in the pipe. The plywood bolts are evenly distributed on the stretched butterfly shape pipe. Although it ensures no deformation in a short period of time, the production is complicated and cannot be improved. Ergonomics, drilling a few holes on the stretched butterfly-shaped pipe will inevitably cause hidden dangers due to the deformation of the rubber pad and easy water leakage or loosening of the splint bolts after a few years
