Intelligent fluid type electric heating box

Abstract

The invention relates to the technical field of heaters, and discloses an intelligent fluid type electric heating box which comprises a base and a shell fixed onto the base. A feeding pipe and a discharging pipe communicating with the inner part of the shell are arranged on the side surfaces, close to two ends, of the shell; a heating assembly is fixed to one end, close to a feed inlet, of the shell; a part, used for heating, of the heating assembly is arranged in the shell; a flow monitoring assembly electrically connected with the heating assembly is fixedly connected into the feeding pipe;temperature monitoring assemblies electrically connected with the heating assembly are fixedly connected to the discharging pipe and the middle part in the shell; the heating assembly is used for heating a fluid medium entering from the feeding pipe; and the flow monitoring assembly and the temperature monitoring assemblies are used for monitoring and controlling the flow speed and the temperatureof the fluid medium, and can stop the heating operation of the heating assembly when the flow speed of the fluid medium is too low or the temperature is too high, so that the occurrence of the phenomenon that the service life of the electric heating box and the follow-up use of the fluid medium are influenced due to dry burning or excessive heating of the heating assembly is avoided.

Description

technical field [0001] The invention relates to the technical field of heaters, more specifically, it relates to an intelligent fluid electric heating box. Background technique [0002] Electric heating is the process of converting electrical energy into heat energy. Since the discovery that the power supply can produce thermal effects through wires, many inventors in the world have been engaged in the research and manufacture of various electric heating appliances. Electric heaters include coiled heaters and fluid heaters. Heaters, different types of heaters have different uses. [0003] Wound plate heaters have a high heat dissipation area, and are mostly used for heating air. Fluid electric heaters are an internationally popular electric heating equipment, which can be used for heating, heat preservation and heating of flowing liquid and gaseous media. heating. [0004] However, since the power of the fluid electric heater is generally relatively large, when the medium ...

Problems solved by technology

[0004] However, since the power of the fluid electric heater is generally relatively large, when the medium flows slowly or is still, it may cause insufficient material inside the heater, which will cause the electric heater to dry and affect the life of the electric heater. If the heater does not stop heating , the medium cannot take away the heat from the inside of the heater in time, which may cause the medium temperature to be too high and affect the subsequent process production
