Embodiment
As shown in Figure 1, the low-temperature startup device of electronic unit of the present utility model, comprise temperature relay 2, sealing box body 4, at least one film heating plate 3 and a plurality of modular unit 1, wherein, modular unit 1 is uniformly arranged and fixed in sealing box body 4, temperature relay 2 also is installed in the sealing box body 4, and each film heating plate 3 is attached to the outer wall of modular unit 1, and the two poles of the earth of each described film heating plate 3 connect temperature relay 2.
As shown in Figure 2, temperature relay 2 is the closed type temperature relay, and it uses minimum ambient temperature to be-55 ℃, and when the ambient temperature rising reached its contact temperature, temperature relay 2 the two poles of the earth disconnected.
As shown in Figure 3, the insulating barrier that film heating plate 3 comprises wire netting and is coated on the wire netting outside, wherein, wire netting is formed by the wire bending of wide 1mm, a thick 0.2mm, and two ends wiry pick out the formation positive and negative polarities with wire; Insulating barrier adopts insulation film; According to the difference of heating power, thickness wiry changes thereupon.Film heating plate 3 collapsible bendings can be close on the modular unit of various profiles.Film heating plate 3 can start under-55 ℃ of low temperature.
As shown in Figure 4, when modular unit 1 was switched in low temperature environment, temperature relay 2 the two poles of the earth were closed at low temperatures, each film heating plate 3 energising heating, and film heating plate 3 is heat transferred modular unit 1, and the modular unit 1 rear temperature of being heated raises.As shown in Figure 5, when modular unit 1 temperature accumulative total be elevated to need temperature after startup work, the electronic unit interior environment temperature continues to raise.When closed type temperature relay 2 ambient air temperatures rose to its contact temperature value, closed type temperature relay 2 the two poles of the earth disconnect stopped power supply, and film heating plate 3 stopped heatings, modular unit 1 continue normal operation under thermal equilibrium condition.
