Description

Technical Field

[0001] The invention relates to an energy-saving radiator, in particular to a multi-tube energy-saving radiator with adjustable flow rate and heat dissipation area. Background Art

[0002] Radiators are mainly used in the cold northern regions in winter and have the function of keeping warm. Cast iron radiators were mostly used in the past, but now radiators of more materials have been developed. Cast iron radiators have gradually withdrawn from the market. New radiators such as steel radiators, copper-aluminum composite radiators and aluminum radiators are superior to cast iron radiators in terms of materials and production processes, and have become the most mainstream radiators on the market. In cold regions such as the Northeast, heaters have replaced fire walls and kangs and become people's new heating equipment.

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

[0004] The above patents and prior art all use flow regulating valves to regulate the flow inside the radiator, and a temperature control valve is added at the entrance of the heat medium of the radiator to adjust the heat dissipation by changing the flow of the heat medium entering the radiator. The regulation method is throttling type with large resistance, and because it is set on the pipe connecting the radiator of the heating system, long-term operation leads to high water pump transportation energy consumption of the heating system and poor energy saving. Moreover, since the temperature control valve needs to be installed, additional construction and cost are required, and system transformation may be required according to different heating systems. In addition, the heat medium is usually hot water with poor water quality, and the temperature control valve is easily blocked due to long-term use of poor water quality, and the maintenance cost is high. In addition, the water hammer phenomenon of the temperature control valve is also more serious, which is easy to cause damage to the pipeline and valve. Moreover, due to the large number of vertical pipes of the radiator, the horizontal pipe and the vertical pipe on the existing radiator are directly connected. When the heat medium passes through, it must pass through all the vertical pipes, and the area and flow cannot be adjusted in the heat dissipation part, resulting in heat waste, and the effect of energy saving and efficiency improvement cannot be achieved. Summary of the invention

[0005] Based on the fact that the prior art cannot adjust the heat dissipation area and the flow rate of the heat medium in the heat dissipation part, resulting in heat waste and failure to achieve energy saving and efficiency improvement, the present invention provides a multi-tube energy-saving radiator with adjustable flow rate and heat dissipation area.
