Electric heating device for rapidly heating liquid

Abstract

The invention discloses an electric heating device for rapidly heating liquid. A liquid storing box is connected with a water pump inlet through a pipeline and a valve, and a water pump outlet is connected to a one-way valve inlet. A one-way valve outlet is connected with a heating module inlet through a pipeline, and a heating module outlet is connected with a pressure storage tank and a pressure gauge through pipelines and a tee joint. The pressure gauge is connected to an outlet valve through a pipeline. A central controller, a power control module, a power module and a heating module are sequentially connected, a temperature sensor is mounted in the heating module, and an intelligent temperature control instrument and a pressure sensor are connected with the central controller. According to the electric heating device for rapidly heating liquid, a PTC electric heating layer and inner fin metal guiding tubes are integrally compounded into a heating unit, and the heating speed is greatly increased; and through fin structures in the metal guiding tubes, the heat transfer area can be increased, and the structural strength of the metal guiding tubes can be improved to enable the metal guiding tubes to bear the high pressure.

Description

technical field [0001] The invention relates to the field of liquid heating equipment, and more specifically relates to a device that can be used for efficient and rapid heating of liquid, especially suitable for places that need to quickly generate high-temperature liquid and steam. Background technique [0002] Existing liquid heating devices generally use a container for heating. There is an electric heating tube in the container. The electric energy is converted into heat energy to heat the liquid in the container through the electric heating wire in the electric heating tube. Since the electric heating wire in the electric heating tube needs to pass through quartz sand and The wall of the electric heating tube forms an insulating layer, so the heat of the electric heating wire must pass through the quartz sand to be transferred to the heated liquid, and the thermal conductivity of the quartz sand is small, and the quartz sand layer is relatively thick, so the heating eff...

The electric energy is converted into heat energy to heat the liquid in the container through the electric heating wire in the electric heating tube. Since the electric heating wire in the electric heating tube needs to pass through quartz sand and The wall of the electric heating tube forms an insulating layer, so the heat of the electric heating wire must pass through the quartz sand to be transferred to the heated liquid, and the thermal conductivity of the quartz sand is small, and the quartz sand layer is relatively thick, so the heating efficiency is low. It takes a long time to heat all the liquid in the container to the required temperature
