(embodiment 1)
Fig. 1 is the front view of the refrigerating plant of embodiments of the present invention 1.Fig. 2 is the profile of Defrosting of Refrigerating Plant device.
In Fig. 1, refrigerating plant 1 has the defroster 5 of refrigerator 2 and straight tube-like.Refrigerator 2 has a plurality of fin 3 and refrigerant pipe 4.Specifically, refrigerator 2 has following structure: the metal refrigerator pipes 4 of the sigmoid that crawls, run through the through hole (not shown among the figure) that forms on the fin 3 separately.
It is 340mm that refrigerator 2 has height dimension A, and width dimensions B is the shape of the rectangle of 240mm.Be that refrigerator 2 is longer in the vertical.As shown in Figure 1, refrigerator 2 is configured in the vertical, and defroster 5 is configured in above-below direction.And defroster 5 is fixed on the place of leaving refrigerator 2 certain intervals by parts 2a.
As shown in Figure 2, defroster 5 has glass tube 6, is configured in the bolt 12 of the opening of the bolt 11 of opening of the heater strip 7 of glass tube 6 inside, the lead 10 that is connected with heater strip 7, cover glass pipe 6 upsides and cover glass pipe 6 downsides.Heater strip 7 has heating portion 8 and the wire portion 9 that is made of metallic resistance.Heating portion 8 constitutes by for example diameter 0.21mm De Tie Chrome line being processed into coiled type (being helical form).By wire portion 9, the heating portion 8 and the lead 10 of heater strip 7 electrically contact in addition.Here, bolt 11 and bolt 12 heat by the heat that heater strip 7 produces.Surpass the mode of their SC service ceiling temperature with the temperature that do not make bolt 11 and bolt 12, bolt 11 and bolt 12 are set at the place of leaving heating portion 8 certain intervals.
Next explanation defrosts with 5 pairs of refrigerators 2 of defroster.By using 5 energisings of 10 pairs of defrosters of lead, heating portion 8 heatings of heater strip 7.The radiant heat that comes spontaneous heating portion 8 is given refrigerant pipe 4, fin 3 by conduction, be melted in refrigerator 2 frost of frost, defrost.
As shown in Figure 1, defroster 5 by above-below direction be arranged on the side (promptly vertically configuration) of refrigerator 2.The total length C of the heating portion 8 of heater strip 7 can equate with the height dimension A of refrigerator 2, on the other hand, when defroster 5 was horizontally installed on the below of refrigerator 2 like that shown in the dotted line X of Fig. 1, the total length of the heating portion 8 of heater strip 7 equated with the width dimensions B of refrigerator 2.Here, the height dimension A of refrigerator 2 is longer than width dimensions B.Therefore, by the defroster 5 of straight tube-like being arranged on the side of refrigerator 2, compare with the below that is arranged on refrigerator 2, the total length C of the heating portion 8 of defroster 5 can be longer.The longer structure of total length C of the heating portion 8 of the heater strip 7 of defroster 5 has following advantage.
By increasing the caloric value of heater strip 7, can shorten the time that defrosting needs, thereby improve the efficient of defroster 5.On the other hand, when design heater strip 7, set serviceability temperature upper limit standard.Serviceability temperature upper limit standard has influence on the life-span of heater strip 7.Be the serviceability temperature upper limit standard setting high-temperature for example, the life-span of heater strip 7 will shorten.In the scope of serviceability temperature upper limit standard,, just must adopt the structure of the total length C that increases heating portion 8 here, in order to increase the caloric value of heater strip 7.Therefore, the defroster 5 of present embodiment is because the total length C of heating portion 8 is longer, so can guarantee the life-span and the caloric value of heater strip.
