As a kind of preferred structure of the present utility model, described electrothermal tube preferably sets in a row.
When the length of rectangular case is longer, can be provided with many row's electrothermal tubes in the described rectangular case.
Like this, extraneous air just must be through too much row's electrothermal tube in the process of rectangular case of flowing through, because many row's electrothermal tube stopping and heat exchange action to air, so, the flow velocity of air is slack-off gradually and temperature raises gradually in the rectangular case, and air is flowed in above-mentioned design and heat exchange combines dexterously, thereby makes the air in the shape housing reach the good thermal effect that adds, therefore, the hot-air that flows out from the rectangular case air outlet just has very high temperature.
Described electrothermal tube preferably adopts the linear electrothermal tube.
Adopt the linear electrothermal tube to have advantages such as easy for installation, compact conformation.
Described electrothermal tube preferably adopts the far infrared quartz electrothermal tube.
Advantages such as quick heating, thermal efficiency height, energy consumption are little because above-mentioned far infrared quartz electrothermal tube has, environmental protection, so, this hot air supply device can generate heat moment, reach the effect of instant heating, saved preheating time, improved production efficiency, simultaneously, this hot air supply device also has advantages such as thermal efficiency height, energy consumption are little, environmental protection.
In order to prevent the loss of hot-air heat in the rectangular case, described housing comprises inner housing, heat-insulation layer and shell body, and above-mentioned shell body is installed on the inner housing, and above-mentioned heat-insulation layer is arranged between inner housing and the shell body.
Described heat-insulation layer preferably adopts aluminium silicate wool.
