Description

Convection type energy-saving superconducting electric heater

Technical Field

The utility model belongs to the technical field of the electrical heating technique and specifically relates to an energy-conserving superconductive electric heater of convection type.

Background

The electric heater is an important heating device, is convenient and practical due to cleanness and sanitation, and is suitable for heating places such as families, offices, hotels, schools, workshops and the like. In particular, in recent years, the country governs atmospheric pollution, protects the ecological environment, and changes coal into electricity, so that the electric heating is more widely applied and popularized.

Most of the existing electric heaters are filled with heat conducting oil, the heat conducting oil is heated by an electric heating tube, the temperature rising speed is slow, and the time is long; on the other hand, the problems of large power of the electric heater, high power consumption and the like are also urgently needed to be solved.

Disclosure of Invention

In order to solve the problems that the existing electric heater has large heating power, low heating rate, poor heat dissipation effect and the like, the utility model provides a convection type energy-saving superconducting electric heater with small energy consumption, good heat dissipation effect, high heat efficiency and high heating speed.

The utility model provides a technical scheme that its technical problem adopted is: the convection type energy-saving superconducting electric heater comprises protective cases on two sides, a controller, a dumping protection device, a temperature control probe and a switch, wherein the controller, the dumping protection device, the temperature control probe and the switch are arranged on the protective cases; the upper horizontal pipe, the lower horizontal pipe and the radiating pipe arranged between the upper horizontal pipe and the lower horizontal pipe are communicated, and radiating fins are arranged on the periphery of the radiating pipe; the upper horizontal pipe is provided with a sealing head and an overheating protection device, and the lower horizontal pipe is provided with a plug; the upper surface of the upper transverse pipe and the lower surface of the lower transverse pipe are provided with ventilating caps with radiating holes; an inner sleeve is transversely arranged in the inner cavity of the lower transverse pipe, the inner sleeve and the two ends of the lower transverse pipe are sealed, and superconducting liquid is arranged in the inner cavity of the inner sleeve; the inner part of the inner sleeve is transversely provided with an electric heating tube, and heat conduction materials are arranged in a cavity around the electric heating tube.

Compared with the prior art, the utility model main advantage:

first, the temperature rise speed is fast. The lower horizontal intraductal superconductive liquid that is filled with, superconductive liquid 20 degrees can gasify, and after the electrothermal tube circular telegram, superconductive liquid absorbs a large amount of heat energy phase transition at once and becomes hot gas and rise to the highest point along the cooling tube, and rethread cooling tube and fin release a large amount of heat energy rapidly, make superconductive liquid become liquid reflux by gas phase transition again and violently manage down, so heat cycle repeatedly, only 5 minutes just can reach the heating temperature of needs.

And secondly, the power is low, and the thermal efficiency is high. Only a small amount of superconducting liquid is added into a sealed cavity of the superconducting electric heater, and the heat efficiency reaches more than 98%. The power of 800 plus 1000 watts can achieve the heating effect of 2000 watts of the common electric heater.

And thirdly, the convection heat dissipation effect is good. The heat radiating fins and the upper and lower ventilation caps form a circulating convection heat radiating space, cold air enters from the lower part, and hot air heated by the heat radiating fins from bottom to top is radiated from the heat radiating holes on the upper part, so that the temperature of the whole room is quickly raised.

Fourthly, energy storage and heat preservation. The heat conduction materials are arranged around the electric heating tube, so that the electric heating tube can be better protected, and heat can be timely transferred to the superconducting liquid through the inner sleeve. After the power failure, certain heat can be stored, so that the heat preservation time of the electric heater is longer, and more energy is saved.
