Title:
STACK-TYPE TEMPERATURE SAFETY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/211295
Kind Code:
A1
Abstract:
A stack-type temperature safety device comprises two Z-shaped electrode members respectively fixed to two side surfaces of a frame having separate compartments (103, 203) in a compartment constructed from a non-metal housing (101, 201) and a cover plate (102, 202). A fusible alloy (104, 204) wrapped by a flux (105, 205) is soldered between the two electrode members. The blocking plate divides the frame (103, 203) into independent compartments for respective fusible alloys (104, 204). An epoxy resin (109, 212) is filled in a gap in the housing (101, 201) and sealed by the cover plate (102, 202). In the event of an abnormal external temperature, heat is transferred to the fusible alloy (104, 204). The fusible alloy (104, 204) contracts, under tension of the flux (105, 205), towards two sides to effectively break a circuit. The safety device further comprises a heating system (200) with overheating protection that can receive a signal from a system to automatically heat the fusible alloy (104, 204), thereby providing the system with double protection.
