Frame, auxiliary-valve assembly are prepared by food-grade stainless steel.
The electronic thermostat material be selected from plastics or food-grade stainless steel can prevent its with coolant liquid contact process
The middle conductive ion that is precipitated influences the performance and safety of fuel cell system.
When original state, the electronic thermostat main valve assembly 8 is in closing and auxiliary-valve assembly 14 is in open shape
State, partial circulating entrance 18 and outlet 16 are in connected state；When fuel cell start-up or output par, c load, power outlet
3 do not power, and electronic thermostat works by no electrical property, and coolant liquid enters from 1 partial circulating entrance 18, flow out from outlet 16, pass through
Water pump is in pile internal flow.Fuel cell is just started to work, coolant liquid temperature be not it is very high, electronic thermostat power supply is at this time
Closed state, a small amount of coolant liquid flow through electronic thermostat, only in pile internal flow, do not flow to radiator, this part coolant liquid
It is very fast to stablize increase ratio, the operation is stable of pile is increased faster, wherein coolant liquid flows to circuit as Fig. 2 block arrow institute
The partial circulating circuit shown, the partial circulating circuit include pile, electronic thermostat, counterbalance valve, filter, water pump and thermometric dress
It sets.
When fuel cell works on, and output loading increases, coolant temperature begins to ramp up (such as 40 DEG C), power outlet
3 start to power, and electronic thermostat is by there is electrical property work；Automatically controlled packet 7 controls heater 5 after being powered, and wraps up outside heater 5
Temperature-sensing wax 6 starts to be heated, and temperature-sensing wax 6 melts and expands, and under the pressure on sealing top 1, the power of temperature-sensing wax expansion produces guide rod 20
Raw thrust, promotion main valve assembly 8 are allowed to be gradually opened and (can also beat in the case where ambient temperature is lower than temperature-sensing wax packet fusing point
Open main valve assembly 8), while compressed spring 10, the pressure of generation and the support force of bracket 11 compress auxiliary spring 12 together, from
And auxiliary-valve 14 is pushed to progressively close off.Coolant liquid enters from systemic circulation entrance 17 at this time, the cooling entered with partial circulating entrance 18
