Description
Technical field
The utility model relates to defrosting heater technical field, refers more particularly to a kind of check valve quartz tube heater.
Background technology
At present, refrigerator air cooling system is more and more by the favor of people, and wind cooling refrigerator needs defrost system as you know, and in current industry, the defrost system of wind cooling refrigerator must have an electric heater for heating, electrical heating easily causes potential safety hazard, so the selection needs of Defrost heater are careful.Perfect along with relevant laws and regulations such as International Environmental Protections, the cold-producing medium of refrigerator progressively changes R600a into from R134a.Due to the inflammable and explosive type cold-producing medium of R600a, international safety standard requires that the surface temperature of heater should more than 394 degree.
The heater of current use mainly contains three kinds, and one is aluminum pipe heater; One is steel pipe heater; Another kind is quartz tube heater.Aluminum pipe heater is more weak in defrost performance; The surface temperature of steel pipe is too high; Quartz ampoule has three kinds: individual layer, bilayer, double layer vacuum tube.Monolayer surface temperature is too high.Bimetallic tube outer tube surface temperature is lower, but inner tube surface temperature compare mono-layer tube can be higher, if Leakage Gas can enter between two-layer pipe by air-vent, R600a belongs to inflammable and explosive, there will be the danger of blast.Double layer vacuum tube price is very high, and power can not do greatly, otherwise surface temperature also can be very high.With regard to this several heater comparatively speaking, bimetallic tube heater low price, makes simple.
