Background technology
Ptc heater is bondd through high-temp glue with corrugated fins aluminum strip after being combined by the PTC thermal sensitive ceramics element of some monolithics
Composition, the more common thermal source making warm-air drier, it has thermal resistance is little, heat exchange efficiency is high remarkable advantage, is a kind of automatic constant-temperature, province
The electric heater of electricity.Its maximum feature is its safety preferably, when warm-air drier breaks down stall, ptc heater because
Cannot fully radiate, power can drastically decline automatically, now the surface temperature of heater maintains and is limited to its Curie temperature left side
Right（Generally 240 DEG C）, thus " rubescent " phenomenon on similar electric tube heater surface will not be produced, eliminate and have an accident
Hidden danger.Due to bringing preferable safety using thermal sensitive ceramics element, so warm up the need of ptc heater with every field wind
The amount of asking is gradually increased, and the ptc heater demand of voltage levels is also stepped up, and therewith the rising bringing due to voltage
What the safety problem that band is related to also became is increasingly paid attention to.
Existing domestic ptc heater mostly structure is relatively simple, is two tip electrode line-outgoing types, single sided lead formula or exposed
Traditional structure design such as riveted type, as the performance of the required electrode slice of pin configuration is high, bending resistance square has high demands, by electrode
Piece and high-voltage wiring harness pass through terminal compression joint to together with when, the excessive extended tips easily causing electrode slice of crimp force fracture, and cause
The scrapping of product, and the single wire harness needing is also many, the bad distribution carrying out gear and assembling；And some adopt monolayer pcb board
It is easier to short circuit between the ptc heater both positive and negative polarity of mechanism, bring very big risk to the safety of itself.
Adopting both positive and negative polarity separate type external ptc heater more（I.e. the spacing between both positive and negative polarity is as big as possible）Structure,
To ensure the insulating properties between both positive and negative polarity with this.But the space due to all multi-heating-pipes has mostly limited, both positive and negative polarity it
Between distance also substantially limit, therefore the more high required insulation distance of voltage is bigger, so how energy under fixing spacing
Ensure the insulating properties between high pressure both positive and negative polarity, just become particularly is important.
