Water circulation type electric heating device

Abstract

A water circulation type electric heating device comprises a radiator and is characterized in that the water circulation type electric heating device further comprises an integrated body fixedly connected with the radiator, a flow collecting channel is formed in the integrated body, the upper end of the flow collecting channel is communicated with a water inlet in the upper portion of the radiator, the lower end of the flow collecting channel is communicated with a water outlet in the lower portion of the radiator, an electric heating pipe which is arranged in the radiator in parallel through the water inlet in the upper portion of the radiator is fixedly connected to the integrated body, and a pressure gauge, a temperature sensor, a circulating water pump and a water flow sensor are arranged on the flow collecting channel of the integrated body. A water filling nozzle controlled by a valve is arranged on the upper portion of the radiator. A connector connected with an expansion tank is arranged on the lower portion of the radiator. The water circulation type electric heating device has the advantages of being compact and reasonable in structure, high in integration degree, high in heat conduction speed, good in heat exchange effect, capable of saving electric energy and achieving partitioned heating easily and the like.

Description

Technical field [0001] The invention belongs to a heating system and is a water circulation type electric heating device. Background technique [0002] At present, heating in winter mainly uses coal-fired boilers for central heating, gas and electric heaters for single household heating, and single households with coal-fired direct-fired boilers for heating. The traditional use of coal and gas heating methods will inevitably pollute the environment, which does not meet the requirements of energy saving, emission reduction, low carbon and environmental protection. [0003] The frequent haze weather in many cities in my country is closely related to traditional coal and gas heating methods. Therefore, it is urgent to solve the environmental protection problems caused by coal and gas heating methods, especially coal-fired heating methods. The ideal heating method is a single-household temperature-controllable heating method that does not pollute the environment. The existing water-ci...

Problems solved by technology

Because the water circulation electric heater of this structure only realizes the water circulation heat exchange by the temperature difference, the water circulation is slow or stagnant, the heat conduction speed is slow, it is not conducive to heat exchange, and the heat exchange area is small. Usually, it can only be improved by increasing the power of the electric heating rod. Heat exchange effect, waste of electricity
