Description
Technical field
The utility model relates to a kind of heater, particularly a kind of ptc heater.
Background technology
Conventional heater used in printed substrate (PCB) industry, many high temperature resistance silks are set uniformly in its high temperature resistant stainless steel seamless pipe, and the gap in seamless steel pipe inserts heat conductivility and all good crystal magnesium oxide powder of insulation property densely, when high temperature resistance silk has electric current to pass through, the heat produced is spread to metal tube surface by crystal magnesium oxide powder, be delivered to by the liquid that heats again, to reach heating object.
The shortcoming of this heater is: 1, the change of environmentally temperature cannot export to regulate the thermal power of self, thus by the power consumption optimal control of heater minimum, can not reduce the utilization ratio of electric energy; 2, heater cannot automatic constant-temperature, when heater is not in a liquid, and the thermostat that configures of heater is when occurring abnormal, heating tube just there will be dry combustion method, temperature sharply raises, cause seamless steel pipe red by burning soon, even pipe such as to puncture at the abnormal conditions, and this problem occurred is fatal in printed substrate (PCB) industry, once heating tube occurs above abnormal, except causing heater failure, also may draw so inflammable printed substrate, cause fire disaster to occur.
Summary of the invention
The purpose of this utility model is to provide a kind of ptc heater with automatic constant-temperature function, even if when heater dry combustion method and thermostat exception, also there will not be heat-generating pipe to burn the phenomenons such as red, pipe punctures, and the utilization ratio of electric energy is high.
A kind of ptc heater described in the utility model, comprise terminal box and be fixed on the metal outer pipe in terminal box, described metal outer pipe inside is provided with the heat conduction support with its contact internal walls, heat conduction support is provided with multiple axial containing cavity, each containing cavity is built with PTC fever tablet, PTC fever tablet Surface coating insulating case, PTC fever tablet has close to one end of terminal box the lead-in wire electrode stretching out insulating case, lead-in wire electrode with stretch into the power line that wiring closes and be electrically connected.
Ptc heater described in the utility model, adopt PTC fever tablet as heater element, utilize the constant temp. warming characteristic of PTC fever tablet, PTC fever tablet powers up rear self-heating and heats up, resistance enters transition district, can the change of environmentally temperature the thermal power of self be regulated to export, PTC fever tablet surface temperature is made to keep steady state value, can by the power consumption optimal control of heater minimum, the thermistor material of high heating efficiency also significantly improves the utilization ratio of electric energy simultaneously, and in the situations such as heater dry combustion method and thermostat exception, also heat-generating pipe is there will not be to burn red, the phenomenons such as pipe punctures, can prevent fire from occurring, and improve the life-span of heater.

Embodiment
As shown in Figures 1 to 3, described ptc heater, comprise terminal box 1 and be fixed on the metal outer pipe 2 in terminal box 1, described metal outer pipe 2 inside is provided with the heat conduction support 4 with its contact internal walls, heat conduction support 4 is provided with multiple axial containing cavity 5, each containing cavity 5 is built with the PTC fever tablet 6 be made up of thermistor, PTC fever tablet 6 Surface coating insulating case 7, PTC fever tablet 6 has close to one end of terminal box the lead-in wire electrode 61 stretching out insulating case 7, lead-in wire electrode 61 with stretch into the power line 3 that wiring closes and be electrically connected.Utilize the constant temp. warming characteristic of PTC fever tablet 6, PTC fever tablet 6 powers up rear self-heating and heats up, resistance enters transition district, can the change of environmentally temperature the thermal power of self be regulated to export, PTC fever tablet 6 surface temperature is made to keep steady state value, can by the power consumption optimal control of heater minimum, the thermistor material of high heating efficiency also significantly improves the utilization ratio of electric energy simultaneously, and in the situations such as heater dry combustion method and thermostat exception, also heat-generating pipe is there will not be to burn red, the phenomenons such as pipe punctures, can prevent fire from occurring, and improve the life-span of heater.
Described heat conduction support 4 can adopt the aluminium of good heat conduction effect to make, it comprises and is placed in the inner and aluminium shape material 41 that the is tubulose of contact internal walls with it of metal outer pipe 2, and the positioning aluminium logical 42 be placed in tubular aluminum shape material 41, described containing cavity 5 is opened in the inner side of aluminium shape material 41, and the position that positioning aluminium leads to 42 corresponding containing cavities 5 is provided with can be stretched into containing cavity 5 and PTC fever tablet 6 is tight against the location lug 421 on the diapire of storage tank 5.
421 bad for avoiding the insulating case 7 outside PTC fever tablet 6 to be pressed by location lug, simultaneously also in order to better heat conduction PTC fever tablet 6 produced is on heat conduction support 4, can arrange copper sheet 8 between PTC fever tablet 6 and location lug 421, PTC fever tablet 6 is tight against on the diapire of containing cavity 5 by copper sheet 8 by location lug 421.
Can better PTC fever tablet 6 be tight against on the diapire of containing cavity 5 to make location lug 421, aluminium patch 9 can be set between copper sheet 8 and location lug 421, this aluminium patch 9 can be trapezoidal aluminium patch, and the PTC fever tablet 6 being coated with insulating case 7 is pushed against on the diapire of containing cavity 5 by aluminium patch 9 and copper sheet 8 by location lug 421 that positioning aluminium leads to 42 successively.
For making PTC fever tablet 6 fit with the diapire of containing cavity better, can be gluing with the diapire high temperature of containing cavity 5 by the insulating case 7 outside PTC fever tablet 6.
