CN2639833Y - Steel aluminium integrated wing type heat radiator of regulation and controlling - Google Patents

Abstract

The utility model relates to a controllable radiator which is made of steel and aluminum and shaped in a wing. The radiator is employed in central heating of healthy housing and can save energy. The three problems of the prior technology are that (1) each radiator is uneven cold and heat according to the designed heating conditions; (2) the aluminum alloy radiator can not bear the corrosion of the hot alkali water so that the radiator leaks water and needs to be painted on the inner surface; (3) the middle-grade radiator which can meet the requirements of the affordable house and the healthy residence and has relatively high craft is in shortage. Thus, the solving technical proposal is that (1) the heat exchange pipe which is made of steel and aluminum and shaped in a wing comprises the main body of the radiator, and the passing water and the heating net steel pipes are both protected by the alkali water from corrosion. The aluminum wing casted outside the pipe is a hollow wing and the heat exchange pipe can be either erected or laid down; (2) the inlet pipe has a self-bring filtering pressure regulation valve to assist the hydraulic balance of the heating net so that the uneven cold and heat can be actively eliminated to make the users adjust conveniently in separated rooms; (3) except the hole plate of valve base is made of copper, the main material is steel and aluminum which is abundant in the middle and west of North China. So the middle-grade radiator with relatively high craft which is shortage in market can be designed.
