Description
Technical field
The utility model relates to PTC ceramic heat field, is specially a kind of Instant heating type PTC water heater.
Background technology
Traditional usual wire electrothermal tube of Instant heating type PTC water heater, during work, surface temperature is very high, and when having air pocket or dry combustion method in water, electrothermal tube can burn out, and can cause water-band electricity, also may 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 cavity adopts aluminium alloy to make, after a long time use (general use 1 year or after several years), water can produce serious corrosion to aluminium alloy, the aluminium hydroxide blocking pipe that corrosion produces, polluted source, and penetrate aluminium alloy cavity further, infiltration is caused to leak, when water enters electrical connection place, produce electric leakage, serious harm personal safety.
PTC electrothermal tube of the prior art, usual employing PTC pottery is as heater element, PTC pottery is bonded between power-on and power-off pole piece by heat conductive silica gel, electrode slice outside is wrapped up in polyimide insulative paper bag again, fill in the aluminum pipe of bearing shell shape, after consolidation, then be placed in stainless steel tube, and make it with stainless steel inside pipe wall near forming.As the patent " a kind of High-Power PTC thermostatic electric heating tube being applied to heating liquid " that the patent No. is 201420291960.
Although this electrothermal tube have employed PTC pottery and instead of traditional heating wire material, substantially increase insulating reliability, extend the service life of heater, general instructions for use can be met, but in production and use procedure, also there are some shortcomings, specific as follows:
One, owing to adopting polyimide insulative paper as insulating barrier, in compression and use procedure, the hard granule foreign wearing and tearing be very easily mixed into, or due to electrode sparking burn the reasons such as insulating paper, and cause the damage of insulating paper, cause heater surfaces charged, produce safety problem.
Two, in this patent, with only the single-side heating of PTC pottery, the other heat of PTC pottery is not easy to send, thus the power density of electrothermal tube is on the low side.
So carry out alternative existing aluminium alloy heater in the urgent need to a kind of new heater, particularly to the further optimization of heater core parts PTC electrothermal tube.
