Heat- accumulation type hot case electric heater

Abstract

The invention relates to a heat accumulation type hot box electric heater, comprising a hot box, radiating fins disposed at the periphery of the hot box, a heat accumulation case disposed under the hot box, an electrical control case and a power source controller disposed at one side of the hot box; heat transfer fluid is charged in the bottom of the hot box, a heat conduction pipe is disposed at the bottom center of the hot box, and a vacuum liquid charging pipe and a hot box temperature sensor are disposed at one side of the hot box. A thermal insulation layer in which heat accumulation material is provided is disposed in the heat accumulation case. The bottom of the hot box in which the heat conduction pipe is disposed is embedded in the heat accumulation case, two electric heating pipes are inserted in the heat conduction pipe and controlled by two different temperature controllers respectively. The inventive electric heater is provided with a simple structure, small electrical power, excellent heat transferring, energy saving and discharge decreasing benefits, a long service life, convenient maintenance, safety and reliability of use.

Description

technical field [0001] The invention relates to a heating device for electric heating equipment, in particular to a heat storage type hot box electric heater. Background technique [0002] Heating in winter plays an extremely important role in people's living environment and physical and mental health. With the continuous improvement of living standards, people's requirements for the comfort of the living environment are also getting higher and higher, so the issue of heating in winter has attracted more and more attention from people, and has been included in the very important agenda of life. At present, not only the northern regions are heating in winter, but many cities in the southern regions are also heating in winter. Electric heater is one of the easiest heating implementations, because it has the advantages of simple structure, convenient installation and use, less one-time investment, and no environmental pollution. However, currently commonly used electric heate...

Problems solved by technology

However, the electric heaters commonly used at present have relatively large electric power, generally 1.5-2.5KW.

In this way, the electric heater not only consumes a lot of electric energy and increases the economic burden of the user, but also has low thermal efficiency due to improper heating and heat transfer and heat dissipation methods, and cannot meet the temperature requirements of indoor heating at all, so it can only be used for indoor partial heating or indoor auxiliary heating.

In addition, traditional electric heaters generally insert the electric heating tube directly into the heat transfer fluid for heating or dry heating, so the surface of the electric heating tube is prone to dirt, which affects heat transfer and is easy to corrode, directly affecting heat transfer efficiency and service life, it is difficult to meet people's requirements for comfort, safety and energy-saving and emission-reducing heating
