The heating radiator started to mature earlier and belonged to Europe, especially Italy. Heating radiators were recognized as the end of the 19th century when Europe matured.
In 1890, the rise of noble residences in Europe, in the form of cast iron embossed single column, the price is extremely expensive, as a luxury in life popular in the upper class.
In the 1900s and 1920s, with the convenience and comfort of heating radiators being widely recognized by the factory and used in high-level social communication places (such as churches and theaters), multi-column, cast iron embossed heating with large heat dissipation was generated. heat sink. A large hall that meets the needs of a large space.
During the 1920s and 1930s, the first revolution of heating radiators produced a single-column steel heating radiator, which significantly increased the production volume and met the social demand.
In the 1930s and 1950s, with the continuous improvement of people's living standards, most people gave up the basic way of heating and heating. Pursue a higher standard of living. This has produced a popular heating radiator, namely multi-column cast iron and multi-column steel heating radiator.
In 1950-1960, people had healed the wounds of the Second World War. A relatively good industrial revolution has been produced and the standard of living has been further improved. While satisfying the comfort of heating, people have put forward higher requirements in terms of energy saving, environmental protection and beautiful decoration. The copper plate heating radiator has become a mainstream product because of its large heat dissipation, simple appearance, generous and moderate price.
From 1960 to 1980, people considered the high heat transfer coefficient of aluminum, and hoped to replace cast iron and steel heating radiators. However, due to the crude and simple shape of the cast aluminum and the inability to solve the problem of alkaline water corrosion, the mainstream of the heating radiator returned to steel during the period of 1980-1990. People can demand that their appearance must be consistent with the modern home style, to meet the requirements of humanization and personalization. According to the current production technology level, most manufacturers generally use argon arc welding process plug-in welding to produce smooth tubular heating radiators.
After 1996, with the popularization of ultrasonic automatic welding (laser welding) process and the reduction of welding cost, domestic manufacturers have been transformed by production equipment, boldly adopting color, using cultural heritage and excellent creativity, and creating with professional international design concepts. A modern steel heating radiator that combines decorative and heating functions.
