Because the housing of this hot air supply device adopts rectangular case, so the two ends of electrothermal tube just can be installed on the rectangular case easily; Because the two ends of its electrothermal tube of this hot air supply device are installed on the rectangular case, the vertical setting of flow direction of air in electrothermal tube and the rectangular case, so, when the electrothermal tube in the air process rectangular case in the external world, electrothermal tube has barrier effect to the air of process, thereby makes the air of process carry out sufficient heat exchange with electrothermal tube, therefore, the firing rate of this hot air supply device is fast, thereby has improved production efficiency.
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.
By the heat-blocking action of above-mentioned heat-insulation layer, can prevent the loss of hot-air heat in the rectangular case effectively, thereby further improve the firing rate of this hot air supply device, also further improved the production efficiency of this hot air supply device.
As further improvement of the utility model, described inner housing is made of the reflectorized material plate.
Described reflectorized material plate preferably adopts stainless steel mirror board.
Because inner housing is made of reflectorized material plates such as stainless steel mirror boards, so, the inner surface of inner housing can form the minute surface reflection, thereby the heat that electrothermal tube is produced can be returned from the inner surface radiation of inner housing, like this, the heat that electrothermal tube produces just can be fully utilized, and therefore, the firing rate of this hot air supply device is further enhanced.
The utility model beneficial effect against existing technologies is:
Because the housing of this hot air supply device is a rectangular case, the two ends of above-mentioned electrothermal tube are installed on the rectangular case, the vertical setting of flow direction of air in electrothermal tube and the rectangular case, so when the electrothermal tube in the air process rectangular case in the external world, electrothermal tube has barrier effect to the air of process, thereby make the air of process carry out sufficient heat exchange with electrothermal tube, therefore, the firing rate of this hot air supply device is fast, thereby has improved production efficiency.
