It is made, cost is high, weight is big；2) cold-storage heat-preserving is carried out using industry oil, has certain oil leak, fires danger；3) use and partly lead
Body piece refrigerating/heating, at high price, power consumption is big, amount of heat/cold of transfer is not easy to discharge outside vehicle, if high fever can also
Burn semiconductor refrigeration sheet；4) overheating protection disconnecting circuit when temperature is higher than limit value, need to be again turned on after cooling down, not only grasp
The problem of work inconvenience can also cause temperature gradient big, 5) it manually starts, car owner needs several minutes of startups into the car in advance to start
Machine opens switch refrigerating/heating again, does not meet consumer's usage behavior custom.
A kind of Portable air chamber cloth cushions with refrigerating/heat inducing functions of Chinese utility model patent CN 201216356Y,
Including can doubling outer layer, insulating, interlayer, cold-storage/accumulation of heat band, air bag layer of cloth, the edge of the outer layer is equipped with slide fastener.This sets
The shortcomings that meter：1) it could first must use after cold-storage/accumulation of heat in low-temperature receiver or heat source, make troubles for consumer；2) quilt completely
Dynamic formula absorbs/releases heat from environment, it is impossible to seat actively be heated or cooled；3) amount of stored heat is limited, and heat finishes once discharging
Just ineffective, the time for playing effect is short.
The comfort level of driver and conductor is the problem that autoist is concerned about the most, and it is one to drive, ride in an automobile
Kind is enjoyed rather than uncomfortable thermal environment is endured in order to reach traffic purpose.Optimize solution temperature adjusting for auto use chair to ask
Topic be Vehicles Collected from Market there is an urgent need to.All kinds of seat temperature equipments in recent ten years show automotive seat temperature adjustment system both at home and abroad
