Further, be coated with anti-flaming thermal-insulation silicon rubber (not shown) on the shell 1 in the heater outside.
Further, the rear side of described heater and both sides are provided with suppression air port and wind path revolution air channel.
The course of work of present embodiment is: heater is formed a U-shaped heating arrangements by three heating modules 2, allow heat-shrink tube heat by the heating region that the U-shaped openend enters U-shaped central authorities, the surface of heating module is equipped with the wire harness of protection network in can preventing to process and damages or the Direct Contact Heating module, the air blast 3 of heating unit is to the air blast of heater direction, and the air channel, air port 4 of heater rear side and both sides causes the air of heating unit inside to flow to form internal heat balance and heat radiation.Timing circuit in the electric cabinet, temperature controller 11 is used to be provided with and control the temperature and the heat time heating time of heating unit, can be triggered automatically to level sensor heat time heating time by the wire harness that is arranged on the heater, or trigger by manual type by the user, automatically send sound/light prompting to the back electric cabinet heat time heating time, electric cabinet is to the overtemperature of heater and owe temperature and carry out dynamic monitoring, do not reach the design temperature scope and refuse timing, contingent timing false triggering action is discerned automatically and forbidden, heat radiation air-bled time after heater stopped to heat is forced control, opens automatically controlled chamber door and forces to draw charged.
Further, electric cabinet in the heat-shrink tube heater of the present utility model, only for the rising edge response of heating the timing commencing signal, for another triggered signal shielding automatically in the setting time-delay after another triggered signal in the heating timing course and the heating timing end just.
Concrete, be lower than 60 degrees centigrade under the shell 1 appearance temperature normal operation.U-shaped heater opening surface is convenient to heat-shrink tube and is sent into heating an actor's rendering of an operatic tune to the user.The U-shaped opening slightly inwardly folds to strengthen the uniformity and the closure of an actor's rendering of an operatic tune temperature.Temperature controller 11 is used to be provided with and control the temperature of heating unit, and to the overtemperature of heating unit with owe temperature and carry out dynamic monitoring, not reaching the design temperature scope will not start in timing.Timing circuit is used for being provided with and calculating heat time heating time, and can be triggered automatically to level sensor heat time heating time by the wire harness on the heating unit, or triggered by manual type by the user, and automatically send sound/light prompting to back acousto-optic hint device 13 heat time heating time.Timing circuit is also discerned automatically contingent timing false triggering action and is forbidden, heat radiation air-bled time after heating unit stopped to heat forces to go up electric control, even operator mistake is operated a switch electric cabinet and also can be guaranteed air discharging and radiating time of setting to guarantee can not produce the overheated even fire of heating unit because mistake is operated a switch.6 pairs of interlock switches of door are charged to be opened automatically controlled chamber door and forces to draw electricity, to guarantee personal safety.Heating power control circuit 12 is directly controlled the heating power supply and the power adjusting of heating unit.
The electric-control system course of work is as follows: after the electric cabinet general supply powers on, on temperature controller 11 temperature range is set, be set heat time heating time on timing circuit.Open temperature detect switch (TDS), heater begins heating, air blast 3 entrys into service by the heating power unit under temperature controller 11 controls.When temperature did not meet or exceed range of set value, timing circuit was refused timing to the heat-shrink tube that enters heater, and acousto-optic hint device 13 also will not be reported.When temperature reached setting range, temperature excess of stroke lamp went out, and allowed heat-shrink tube to begin to heat timing.At this moment timing circuit carries out timing to the heat-shrink tube that enters heater, and timing is reported that to back acousto-optic hint device 13 can remove heat-shrink tube this moment from heater.In a process-cycle timing finished the back regular hour, new heat cycles can not begin, and removed the heat-shrink tube that heating finishes the enough time to give the operator, prevented to heat the timing false triggering.This time can directly be provided with on the time relay in electric cabinet.In a heating cycle, once heat timing if trigger again, this triggering is shielded automatically, and heating still continues by former heating cycle.Close temperature detect switch (TDS) after the process finishing, this moment, heater stopped heating, and beginning is cooled off under the effect of air blast 3.Air blast 3 stops behind certain hour automatically, and this time can directly be provided with on the time relay in electric cabinet.If the electric cabinet total power switch is closed in this time, air blast 3 is still pressed setting-up time operation, and preventer is owing to not having air-cooledly to cause overheated even fire.3 cool times of air blast to after stop automatically, close the electric cabinet total power switch this moment.After the electric cabinet general supply was closed, electric cabinet was still charged, and for preventing to get an electric shock, in case automatically controlled chamber door is opened, door interlock switch 6 cuts off immediately and advances electricity, and electric cabinet is no longer charged.
