Air door self-closing type air-cooled ceramic heater with heat insulation function

Abstract

The invention discloses an air door self-closing type air-cooled ceramic heater with a heat insulation function. The air door self-closing type air-cooled ceramic heater comprises a ceramic heater, wherein a stainless steel air-cooled outer cover is arranged outside the ceramic heater; a heat insulation layer is arranged on the inner surface of the stainless steel air-cooled outer cover and is made of high-temperature-resistant cotton and a stainless steel sheet; the air-cooled outer cover is provided with a fan, a fan mounting seat, fan mounting thread holes, mounting screws, an air inlet, air door leaves, a leaf bracket, limiting sheets and an air outlet. The air door self-closing type air-cooled ceramic heater has the advantages that when the heater performs heating operation, heat can be insulated, so that rising of environment temperature is controlled, the scalding accident caused by over-high shell temperature is prevented, and the effects of safety, environmental friendliness and energy conservation are achieved; when equipment needs to be cooled, the fan operates, the air door leaves are automatically opened, the heat of the equipment can be quickly dissipated by virtue of cold air which is blown in, and the temperature is accurately controlled; when the fan stops operating, the air door leaves are automatically closed to prevent the heat loss and return of the heater, so that the heat loss is avoided, and the damage to the fan caused by over-temperature due to the return of heat is avoided.

Description

Technical field [0001] The invention relates to an air-cooled ceramic heater, in particular to an air-cooled ceramic heater with heat insulation and a self-closing air door. Background technique [0002] 1. Electric heater is an indispensable device in plastics, chemical, chemical fiber, mold and other industries. In the actual application of the air-cooled heater, because the heat is transferred by conduction, about 50% of the heat is radiated outwards, causing serious heat loss and a huge waste of energy. In addition, the heat emitted makes the temperature of the heater cover too high, which is prone to burn accidents. [0003] 2. As ordinary air-cooled heaters automatically radiate heat outwards, the outside environment temperature rises, especially for manufacturers in summer or tropical regions. Because the production environment temperature is too high, it affects the normal operation of other equipment, and at the same time operating equipment personnel The comfort level i...

AI Technical Summary

Problems solved by technology

In the actual application of the air-cooled heater, because the heat is transferred by conduction, about 50% of the heat is dissipated by radiation, resulting in serious heat loss and a great waste of energy.

And the heat emitted makes the temperature of the heater cover too high, which is prone to burn accidents

[0003] 2. Because ordinary air-cooled heaters automatically dissipate heat outward, the temperature of the external environment rises, especially in summer or in tropical regions. Due to the high temperature of the production environment, the normal operation of other equipment is affected. At the same time, the equipment operators Decreased comfort, even unbearable, seriously affecting normal production operations

[0004] 3. The cooling method of the traditional air-cooled ceramic heater usually uses the fan and the outer cover to blow the air to achieve the purpose of controlling the rapid cooling of the electric heater. There is an air inlet at the joint between the fan and the outer cover. When the fan stops and the heater works, there will be a large amount of air. The heat emitted by the fan is radiated outward through the air inlet, resulting in a waste of energy. Most of the emitted heat is absorbed by the fan, which can easily cause the fan to be overheated and burn out, which will affect the production of the whole machine.
