Energy-saving type silicon crystal film ceramic electric heating warm air furnace

Abstract

An energy-saving type silicon crystal film ceramic electric heating warm air furnace comprises an outer shell, a fan unit and a heating unit, wherein the fan unit and the heating unit are arranged in the outer shell. An air returning opening and an air feeding opening are formed in the outer shell. The fan unit is provided with an air inlet and an air outlet. The air inlet of the fan unit is communicated with the air returning opening of the outer shell. The heating unit is arranged between the air outlet of the fan unit and the air feeding opening of the outer shell. The energy-saving type silicon crystal film ceramic electric heating warm air furnace is characterized in that the heating unit comprises at least one heating module; the heating module comprises a support, a supporting seat arranged on the support and a silicon crystal film ceramic heating body arranged on the supporting seat; and heat energy generated by the silicon crystal film ceramic heating body is sent outside through air on the air outlet of the fan unit and is sent to areas needing to be heated through the air feeding opening of the outer shell.

Description

Technical field: [0001] The invention relates to an energy-saving silicon crystal film ceramic electric heater, which is mainly used in industrial and agricultural production and belongs to high-power heating equipment. Background technique: [0002] At present, electric heating stoves used in industry and agriculture require relatively large power (tens of kilowatts), mainly using coal (gas) to directly heat the air, and then the hot air is directly sent to the air through the pipeline by the strong exhaust fan on the electric heating stove. Go to the place to be heated, and at the same time, the indoor and outdoor air can be drawn back through the return air pipe for reheating. This heating method has a relatively small investment in equipment, and because it directly passes through the heated air, it has the advantages of small heat loss and fast heating time. But it also has the following defects: 1. The regulation and control of coal (gas) furnaces is still not flexibl...

AI Technical Summary

Problems solved by technology

But it also has the following defects: 1. The control of coal (gas) furnace is relatively not flexible enough

2. By burning coal (gas) to generate heat, it causes great environmental pollution

3. As the price of coal (gas) rises, the operating cost is also increasing

[0003] In order to solve the above problems, some enterprises at home and abroad are currently rewarding the development of electric heaters to replace coal (gas) heaters for heating. However, ordinary iron-chromium-aluminum heating elements are used as heating elements. After that, various phenomena such as power reduction or burnout appear, making the operation of the whole equipment unstable, unable to carry out market promotion, and low energy efficiency
