Embodiment
Electronic component is damaged in order to prevent electric heater unit from overheating, and can be faster extensive after electric heater unit overheat
Normal working temperature is arrived again, and the utility model provides a kind of electric heater unit, described in detail by the following examples.
The electric heater unit of the present embodiment referring to shown in Fig. 1, Fig. 2, including：At least 2 electric heating tubes 1, in the present embodiment
By taking three electric heating tubes 1 as an example, three electric heating tubes 1 are fixed together by interface unit 2.Temp. control cap 3 is concave, similar
Lid, Over-temperature Thermal Protection Switch 4 and temperature controller joint 5 is provided with the depression one side of Temp. control cap 3, the overtemperature guarantor in the present embodiment
Shield thermoswitch 4 preferably uses Self-resetting Over-temperature Thermal Protection Switch, is additionally provided with cable interface 6 on Temp. control cap 3, is connect by cable
6 temperature controller joints 5 of mouth are connected to temperature controller 7.The depression one side of Temp. control cap 3 is connected with three electric heating tubes 1 being fixed together,
One end of three electric heating tubes 1 is preferably fixed on using ring flange 13 in specific implementation, then with Temp. control cap 3 connect or block
Connect, and after linking so that Over-temperature Thermal Protection Switch 4 and temperature controller joint 5 are in contact with electric heating tube 1, realize that heat passes
Lead, and then Over-temperature Thermal Protection Switch 4 and temperature controller joint 5 can be synchronous with the temperature of electric heating tube 1.When thermoswitch 4 is examined
When measuring electric heating tube overheat, temperature controller 7 acts, and triggering Over-temperature Thermal Protection Switch 4 disconnects, so as to cut off the electricity supply.
To realize the quick heat radiating after electric heater unit overheat, electric heater unit also includes what is matched with electric heating tube 1
Fin 8, fin 8 are provided with magnet 9, and electric heating tube 1 is provided with calutron 10, set between fin 8 and electric heating tube 1
Flexible attachment means 11, it can specifically use spring structure or sponge elastic mechanism.Relay is additionally provided with Temp. control cap 3
12, and relay 12 is electrically connected with above-mentioned Over-temperature Thermal Protection Switch 4, calutron 10, temperature controller joint 5.Normally
Under state, fin 8 is pushed away electric heating tube 1 by elastic connecting device 11.But while Over-temperature Thermal Protection Switch 4 triggers,
Starting relay 12, relay 12 act, and connect the wire loop of calutron 10, and calutron 10 obtains electric generation electromagnetism and inhaled
Power, overcome the thrust of elastic connecting device, fin 8 is attracted into docile to electric heating tube 1 using the attraction to magnet, dissipate
Backing 8 can be very good auxiliary heat dissipation.Over-temperature Thermal Protection Switch 4 switchs for self- recoverage, recovers to disconnect while connection status
The wire loop of relay 12, the dead electricity of relay 12, the dead electricity of calutron 10, electromagnetic force are disappeared, and fin 8 is pushed away from.So
Just realize the switching of heating mode and radiating mode.
In order to prevent that electric heating tube 1 and other electron component from being collided with, the present embodiment is preferably using rigidity supporting structure
Protective case 14, the surface of protective case 14 are provided with heat emission hole, and heat emission hole can be consistent with the shape of fin 8, it is of course possible to also adopts
Realized and radiated with forms such as cellular perforates.
In the specific implementation, one of cut-in relay 12 after by Over-temperature Thermal Protection Switch 4 and the parallel connection of temperature controller joint 5
Switch terminal, by another switch terminal of the cut-in relay 12 of calutron 10.By taking the static liquid of heating as an example, referring to Fig. 3 institutes
Show, support 15 is connected on Temp. control cap 3, and be supported in container edge, make the electric heating tube 1 of the electric heater unit of the present embodiment
Immerse in liquid, the circuit loop conducting of electric heating tube 1 after upper electricity, electric heater unit is begun to warm up, if there is electric heating tube 1
Temperature exceed 4 default temperature of Over-temperature Thermal Protection Switch, then Over-temperature Thermal Protection Switch 4 acts, and disconnects to electric heating tube 1
Power supply, and circuit switching to the other end is realized the conducting of the circuit loop of calutron 10, magnet 9 is inhaled by relay 12
Close, and then fin 8 is in contact with electric heating tube 1, realize quick heat radiating.Using Self-resetting overtemperature prote heat in the present embodiment
Quick switch, when the continued down of electric heating tube 1 makes Over-temperature Thermal Protection Switch 4 meet Self-resetting temperature, overtemperature prote temperature-sensitive is opened
4 Self-resettings are closed, so that relay 12 completes circuit switching, the circuit loop of electric heating tube 1 is turned on again, continues to add liquid
Heat.And after circuit switching, the power-off of calutron 10 loses magnetism, and based on elastic connecting device 11, makes calutron 10 and magnet 9
Depart from, and then fin 8 is separated with electric heating tube 1.In addition, dual protection mechanism is additionally provided in the present embodiment, temperature controller
Joint 5 conducts the temperature of electric heating tube 1 in real time, you can to monitor the temperature of electric heating tube 1 in real time by temperature controller 7, such as occurs
The situation of overtemperature, the circuit loop that can disconnect electric heating tube 1 at any time are switched to radiating mode, and can be according to electric in radiation processes
The temperature change of heating tube 1 switches back into heating mode at any time, will not be repeated here.
Here description and application of the present utility model are all simply illustrative and exemplary, are not intended to this practicality is new
