Description
Technical field
The present invention relates to PTC-ceramic heating art, a kind of Instant heating type PTC water heater.
Background technology
Traditional Instant heating type PTC water heater usual tinsel electrothermal tube, during work, surface temperature is the highest, and in the case of having air pocket or dry combustion method in water, electrothermal tube can burn out, and water can be caused charged, it is also possible to cause fire.Due to the heated at constant temperature characteristic of ptc material, safe and reliable, obtain application at Instant heating type water heating art.But a lot of water heater product cavitys use aluminium alloy to make, after a long time use (after generally using 1 year or several years), water can produce serious corrosion to aluminium alloy, the aluminium hydroxide blocking pipeline that corrosion produces, polluted source, and penetrate further into aluminium alloy cavity, infiltration is caused to leak, when water enters at electrical connection, produce electric leakage, serious harm personal safety.
PTC electrothermal tube of the prior art, generally use PTC-ceramic as heater element, PTC-ceramic is bonded between power-on and power-off pole piece by heat conductive silica gel, wrap up in polyimide insulative paper bag again outside electrode slice, fill in the aluminum pipe of bearing shell shape, after consolidation, then it is placed in stainless steel tube, and is allowed to stainless steel inside pipe wall against forming.Patent " a kind of High-Power PTC thermostatic electric heating tube being applied to liquid heating " such as Patent No. 201420291960.
Although this electrothermal tube have employed PTC-ceramic and instead of traditional heating wire material, substantially increase insulating reliability, extend the service life of heater, general use requirement can be met, but during producing and using, there is also some shortcomings, specific as follows:
One, owing to using polyimide insulative paper as insulating barrier, during compressing and using, the hard granule foreign being easily mixed into weares and teares, or owing to the reasons such as insulating paper are burnt in electrode sparking, and cause the damage of insulating paper, cause heater surfaces charged, produce safety problem.
Two, in this patent, with only the unilateral heating of PTC-ceramic, the other heat of PTC-ceramic is not easy to send, thus the power density of electrothermal tube is on the low side.
So substituting existing aluminium alloy heater, the particularly further optimization to heater core parts PTC electrothermal tube in the urgent need to a kind of new heater.
Summary of the invention
The technical problem to be solved in the present invention be overcome prior art heater product cavity use aluminium alloy make, perishable, infiltration, etc. unsafe problems, it is provided that surface use rustless steel, can be with the Instant heating type PTC water heater of the PTC electrothermal tube of two-side radiation.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of Instant heating type PTC water heater, it is characterized in that including PTC electrothermal tube and water tank, the tangent to periphery direction of the bottom of described water tank is provided with oral siphon, the top of described water tank is provided with PTC electrothermal tube, the sidewall on described water tank top is provided with outlet pipe;The guiding gutter of current deflecting sheet or screw type it is provided with in described water tank;
PTC electrothermal tube, including stainless steel tube, in described stainless steel tube, it is provided with several PTC-ceramic heaters radially arranged, in the gap between the PTC-ceramic heater that each two is adjacent, is provided with aluminium section bar, in the gap of aluminium section bar and stainless steel inside pipe wall, is provided with thermal conductive sand.It is provided with aluminium section bar in the gap between the PTC-ceramic heater that each two is adjacent, achieve the two-side radiation of PTC-ceramic heater, heat is transmitted rapidly by the arc surface of aluminium section bar, the power making PTC-ceramic must be in fully playing, the quantity of PTC-ceramic can reduce relatively, the operating temperature of PTC-ceramic can ratio relatively low, thus its power aging is smaller, and service life is obviously prolonged.
Further, when described PTC-ceramic heater is uniformly distributed in stainless steel tube, when the number of described PTC-ceramic heater is one or more, described aluminium section bar be shaped as semicircle or sector.
Further, it is preferred that described insulating heat-conductive pottery is trench structure or slab construction, it is preferred that described insulating heat-conductive pottery is aluminium oxide ceramics.
PTC-ceramic heater transfers heat to adjacent fan-shaped aluminium section bar, is transferred heat on stainless steel tube by the arc surface of fan-shaped aluminium section bar.In order to easy for installation, the diameter of fan-shaped aluminium section bar is less than the internal diameter of stainless steel tube, and leaves certain gap, in order to convenient for assembly, fills up thermal conductive sand in gap.
In order to solve owing to using polyimide insulative paper as insulating barrier, during compressing and using, the hard granule foreign abrasion being easily mixed into, or owing to the reasons such as insulating paper are burnt in electrode sparking, and cause the damage of insulating paper, causing heater surfaces charged, produce safety problem, the present invention adopts the following technical scheme that:
The PTC-ceramic that is arranged in aluminum pipe shell, electrode slice, insulating heat-conductive pottery, polyimide insulative paper is included at described PTC-ceramic heater;Described electrode slice is arranged on described PTC-ceramic surface by heatproof silica gel;Described PTC-ceramic is fixed in insulating heat-conductive pottery by heatproof silica gel, and described polyimide insulative paper bag is rolled in described insulating heat-conductive ceramic outer.
PTC electrothermal tube, by using insulating heat-conductive pottery as insulant, uses polyimide insulative thin film as second layer insulant at insulating heat-conductive top ceramic layer, it is achieved that double insulation, further reinforced insulation performance simultaneously.Using the insulating paper of flanging, by the width control system of insulating paper flanging, it is possible to achieve to insulating heat-conductive pottery, PTC and the location of electrode slice, even if there are the tiny grains of sand simultaneously, also not resulting in heating pipe racks electricity, it is ensured that the insulating reliability of electrothermal tube.
On the other hand, between all coupling parts (include PTC and electrode slice, between insulating heat-conductive pottery and electrode slice and insulating paper etc.) all use heat conductive silica gel bonding, to increase heat conductivity, by the gap in employing silicone filler aluminum pipe, make the side insulation of PTC-ceramic, thus prevent under high pressure the electric discharge between upper/lower electrode, substantially increase the reliability of electrothermal tube.
Further, described aluminium section bar is provided with ground connection string holes.
Further, described polyimide insulative paper is grooved flanging or circular tube shaped.
Further, the model of described stainless steel tube be 304,316Ti pipe or other metal materials.
In order to increase antiseptic effect further, stainless steel pipe surface can be provided with anticorrosive paint, described anticorrosive paint is Teflon, heatproof ceramic glaze, or other heatproof anticorrosive paint.
Beneficial effects of the present invention:
One, the present invention uses the PTC electrothermal tube of stainless steel casing, its corrosion resistance is significantly better than aluminum alloy materials, thoroughly solve the problem being easily corroded of aluminium alloy, and the service life of PTC electrothermal tube is long, good insulating, reliability is high, and then extends service life and the security performance of Instant heating type PTC water heater;
Two, the water inlet pipe of the present invention is arranged on the tangent to periphery direction of bottom of water tank, be additionally provided with the guiding gutter of current deflecting sheet or screw type in water tank, it is achieved current high speed rotating, it is to avoid dead angle, the heat on PTC electrothermal tube surface is quickly taken away, improves the power of heater;
Three, the outlet of the present invention is arranged on the highest point of water tank, after the air in water is precipitated, can be gone out by current, prevent air pocket.
