Abstract
The utility model provides a low-temperature co-fired ceramic heater which is realized by the steps that a heating resistive film is printed on a ceramic substrate which is manufactured by dry pressing, and the shape of the resistive film is designed into an M shape; then the resistive film is coated by a dielectric layer to put into a ceramic kiln for low-temperature co-firing (less than 900 DEG C); and an outer lead wire is welded on the co-fired product to form the low-temperature co-fired ceramic heater; and when the outer lead wire is connected with a circuit, and the resistive film can produce heat to generate heat energy. The low-temperature co-fired ceramic heater can be widely applied to various devices requiring electrical heating.
Description
Affiliated technical field
The utility model relates to a kind of electric heater unit, especially a kind of electric heater unit by the ceramic material sealing.
Background technology
At present, all kinds of electric heater heating elements mainly contain PTC ceramic heating element, heating wire, electrothermal tube, quartz ampoule etc., and the utensil of these traditional heater element assemblings is restricted in market and application gradually because of the defective performance of heater itself, as the PTC ceramic heating element, its thermal shock electric current is big, can only be processed into sheet, and maximum operation (service) temperature is no more than 300 ℃, and electrode easily decays, the element power decay is serious, contains a large amount of lead simultaneously, does not meet environmental requirement; Heating wire heating has naked light, easily strikes sparks during loose contact, arcing, produces potential safety hazard, and can not be applicable to occasions such as high humidity, high salt fog, and component life is short; Other heating element such as electrothermal tube, quartz ampoule etc., it is shaped as tubulose, can only be used for than the large space occasion, and electrothermal tube is when internal resistance silk scintillation, and easy and shell produces electric leakage, and is dangerous.There is such or such defective in existing in a word these heating elements, have seriously influenced their application.
Summary of the invention
In order to overcome the deficiency of existing heating material and components and parts, the utility model provides a kind of LTCC heater, and this heater is quantity of heat given up directly, and does not contain or harmful element such as any heavy metal of indiffusion.
The technical scheme that its technical problem that solves the utility model adopts is: at first print the heating resistor film on one deck ceramic substrate that dry-pressing makes, the resistive film shaped design becomes M shape, and then cover a dielectric layer thereon, it is low temperature co-fired in the kiln to pack into, welds the riveting lead-in wire again and just makes the LTCC heater.When power supply was received on the outside lead, the resistive film heating in it produced heat, and heat becomes heater by ceramic substrate transmission output.
The beneficial effects of the utility model are: because the insulation of LTCC heater surfaces, heating resistor and air are isolated, not oxidation, so stable performance, long service life, LTCC heater surfaces heating-up temperature is even simultaneously, thermal inertia is little, quick heating, so it is energy-efficient; Owing to ceramic material dielectric strength height, volume resistance is big, so this heating element is safe and reliable again.

Among the figure 1, ceramic substrate, 2, resistive film, 3, dielectric layer, 4, outer lead
Embodiment
As shown in the figure, the resistive film 2 that printing is used to generate heat on one deck ceramic substrate 1 that dry-pressing makes, the shaped design of resistive film 2 becomes M shape, cover one deck dielectric layer 3 more thereon, the ceramic kiln of packing into low temperature co-fired (＜900 ℃) behind the kiln discharge, welds riveting outer lead 4 again.During use outer lead 4 is connected with the mains, the resistive film 2 of this heater promptly generates heat and produces heat and heat.
Claims (2)
1, a kind of LTCC heater is gone up printing heating resistor film (2) at ceramic substrate (1), and blanket dielectric layer (3), weldering riveting outer lead (4), and it is characterized in that: heating resistor film (2) is clipped between ceramic substrate (1) and the dielectric layer (3).
2, LTCC heater according to claim 1 is characterized in that: heating resistor film (2) be shaped as M shape.
