3results about How to "Reduce thermal aging" patented technology

The application relates to the technical field of LED lamps, in particular to an LED lamp which comprises a shell and an LED lamp plate arranged in the inner cavity of the shell, and a gap for air circulation is formed between the panel edge of the LED lamp plate and the inner wall of the shell. The application creates a natural air circulation channel in the lamp shell by reserving the gap between the LED lamp plate edge and the shell inner wall, allows the internally accumulated hot air to naturally convect outward through the gap, and meanwhile, the cooler air outside can also supplement into the gap, forming a passive heat dissipation air duct. This effectively alleviates the problem of internal heat accumulation caused by the closure of the shell, reduces the operating temperature of the LED lamp plate and electronic components, slows down the thermal aging, and significantly improves the service life and light efficiency stability of the lamp in an outdoor closed environment.

The utility model provides a kind of intumescent fire-retardant fireproof coiled material, especially relate to fireproof coiled material technical field, including metal foil wrapping layer, the inner side of metal foil wrapping layer is integrally formed with metal foil separating sheet, metal foil separating sheet is equidistantly distributed in the inner side bottom of metal foil wrapping layer, the utility model places fire-retardant package 4 between the inner side of metal foil wrapping layer 1 adjacent two metal foil separating sheets 3, and fire-retardant package 4 is aluminium hydroxide, magnesium hydroxide, red phosphorus and glass fiber storage bag composition, aluminium hydroxide, magnesium hydroxide, red phosphorus are stored by glass fiber storage bag, aluminium hydroxide decomposes and generates water vapor and alumina protective layer under high temperature environment, magnesium hydroxide and aluminium hydroxide compound can widen fire resistance temperature range, and red phosphorus generates phosphoric acid by heating, catalytic carbon and release phosphorus-containing free radical inhibit combustion;Phosphate and carbon source synergistically form intumescent carbon layer, improve heat insulation, reach the effect of intumescent fire-retardant.

This utility model discloses a magnetoelectric speed sensor for monitoring engine speed, including a housing and a body installed inside the housing. A probe body is disposed inside the body, and a probe base is disposed on the rear side of the housing. Connecting lines are disposed on the rear outer wall of the probe base near both the left and right sides. Multiple bonding pieces are equidistantly disposed on the circular outer wall of the body, and a heat-conducting rod is fixedly connected to one end of each bonding piece. Multiple heat dissipation columns are disposed inside the circular outer wall of the housing. By installing the bonding pieces, heat-conducting rod, and heat dissipation columns, the heat dissipation columns dissipate heat to the outside of the housing, effectively reducing the body temperature and minimizing thermal aging of electronic components caused by prolonged exposure to high temperatures. This ensures the stable performance of electronic components and guarantees that the signal processing circuit can accurately amplify, filter, and shape the sensed signal.
