When described heater coil was installed on the number coil support board, the major axis of heater coil elliptical shape in cross-section was in air-flow direction.
The coil heater of cloth drying machine comprises: the heater case that forms the rectangular shape of inflow entrance and outlet; The transverse direction isolation is fixing at regular intervals in heater box interior, forms a plurality of number coil support board in most holes; The heater coil of laterally inserted number coil support board; The cross section of heater coil is wound in elliptical shape; Most holes that form on the number coil support board form a plurality of row along air-flow direction, and the hole of a plurality of row is that benchmark is symmetrically formed up and down with the number coil support board horizontal center line, and the hole of each row that adjoins each other is different mutually with the distance of center line.
The hole of described each row that adjoins each other is different mutually with the distance of the horizontal center line of number coil support board, and the hole of odd column is identical separately in odd column and even column with the distance of horizontal center line with the hole of even column
The hole of described each row that adjoins each other, it respectively is listed as varying in size of hole.
The winding shape of described heater coil is oval
The invention has the beneficial effects as follows: the winding shape of heater coil of the present invention is oval, the flow impedance of the air of process heater coil 14 is less, and prolonged the time that contacts with moving air, have the effect of the heater coil heat exchanger effectiveness that improves coil heater.
And, improve most hole arrangement architectures that form on the number coil support board, can evenly heat the air of the heater coil that is provided with through most holes of perforation, have the effect of the heat exchanger effectiveness that improves coil heater more.
