Description
Technical field
The utility model relates to electric heater fields, and in particular to a kind of electric heater.
Background technique
It in the heating system of passenger car, especially needs to heat repeatedly in a short time, what is generallyd use is positive temperature system
Several resistors is as heating element, i.e., known PTC.PTC resistor is typically characterised by, and is at low temperature in low resistance
State, as temperature increases, resistance increases, and in turn result in the electric current for flowing through PTC reduces as temperature increases.Therefore, work as electric current
When flowing through PTC, material property is heated PTC, and increases its resistance.In this way, the electric current for flowing through resistance reduces, heat
Power then also reduces.In general, when the fever of resistance reaches in a basic balance with heat dissipation, temperature can be stablized with electric current
On a preset value.The automatic control temperature characteristics of this PTC fundamentally avoid the risk of electrical resistance overheats.In view of above-mentioned automatic control
The optimum Working of temperature characteristics and collateral security electric heater consider, in fact, PTC how effectively to radiate need to consider it is clear.
For these reasons, this electric heater product needs it is considered that when heating for air or other fluids, must
Must design has the radiator or radiating subassembly that can guarantee heat exchange, and the connection relationship between heating element and thermal component
Influence whether heat transfer efficiency and radiating efficiency.
