Description

TECHNICAL FIELD

[0001] The present application relates to an energy-saving radiator, in particular to a multi-pipe energy-saving radiator with adjustable flow size and heat dissipation area. BACKGROUND

[0002] The radiator is mainly used in cold northern regions in winter and has a warming effect. Previously, cast iron radiators were mostly used, and now more material radiators have been developed. Cast iron radiators have gradually withdrawn from the market stage. Steel radiators, copper-aluminum composite radiators, and aluminum radiators, etc. are superior to cast iron radiators in terms of material and manufacturing process, and have become the most mainstream radiators on the market. In cold regions such as the northeast, radiators have replaced firewalls and fire bunks to become new heating equipment for people.

[0003] At present, the patent with the application number 2017207274868 discloses a water heating radiator, which comprises a box body, a water tank fixedly connected to the right end of the inner cavity bottom of the box body, a radiator fixedly connected to the middle end of the inner cavity bottom of the water tank, a fan fixedly connected to the left end of the inner cavity bottom of the box body, an air outlet pipe movably connected to the air outlet of the fan, and a water inlet opening formed in the right end of the top of the box body. The utility model discloses a motor flow regulating valve movably connected to the inner surface of the water inlet pipe and a temperature sensor embedded on the lower end of the left side of the outer surface of the box body. When the indoor temperature is relatively low, the motor flow regulating valve power is automatically turned on, and the side with large flow regulating value is increased to increase the supply of heat. When the indoor temperature reaches a relatively moderate temperature, the original flow value is automatically restored, solving the problem that the heat dissipation rate of the existing water heating radiator cannot be changed according to the change of indoor temperature, which not only leads to an unsatisfactory heat dissipation effect, but also causes resource waste.

[0004] The above patent and prior art both use flow regulating valves to regulate the flow inside the radiator. A temperature control valve is added at the inlet of the heat medium of the radiator to adjust the heat dissipation by changing the flow of the heat medium entering the radiator. This adjustment method is throttling type with large resistance. Since the temperature control valve is installed on the pipeline connecting the radiator in the heating system, long-term operation leads to high energy consumption of the water pump in the heating system and poor energy saving. In addition, the temperature control valve needs to be installed, which requires additional construction and cost, and may also need to be reformed according to different heating systems. In addition, the heat medium is usually hot water with poor water quality, which is easy to block the temperature control valve after long-term use, resulting in high maintenance cost. In addition, the water hammer phenomenon of the temperature control valve is also serious, which is easy to cause damage to the pipeline and valve. Since the number of vertical pipes of the radiator is large, the horizontal pipe and vertical pipe of the existing radiator are directly connected. When the heat medium passes through, it must pass through all the vertical pipes, which cannot adjust the area and flow of the heat dissipation part, resulting in waste of heat and failure to achieve the effect of energy saving and efficiency improvement. SUMMARY

[0005] Based on the fact that the heat dissipation area and the flow of heat medium cannot be adjusted in the heat dissipation part in the prior art, heat is wasted, and the energy saving and efficiency increasing cannot be achieved, the application provides a multi-tube energy-saving radiator with adjustable flow size and heat dissipation area.
