The invention belongs to the technical field of LED driving power supplies, and particularly relates to a software-defined LED driving power supply. The software-defined LED driving power supply comprises a driving power supply body, wherein a protective sleeve is arranged on the outer side of the driving power supply body; the protective sleeve comprises a first outer shell and a second outer shell; the first outer shell is provided with a clamping groove in the end face making contact with the second outer shell; and the second outer shell is provided with a clamping strip clamped with the clamping groove on the surface making contact with the first outer shell. According to the invention, opening and closing of the rectangular heat dissipation groove are achieved through rotation of a heat conduction plate, so that the rectangular heat dissipation groove can be opened for heat dissipation in hot weather, the rectangular heat dissipation groove is sealed through the heat conduction plate in cold weather, the external cold air can be prevented from invading the driving power supply body to result in damage of the driving power supply body. According to the design of the invention,the driving power supply body can be prevented from being burnt down due to overheating, and meanwhile, the situation that the working performance of the driving power supply body is reduced and eventhe driving power supply body cannot work normally due to cold invasion is also avoided.

A vaporization latent heat energy reuse system of a liquefied natural gas boat comprises a spiral gas channel. The spiral gas channel is arranged on the outer wall of a natural gas pressure reducing valve, an outlet of the spiral gas channel is communicated with a device needing cooling, and an inlet of the spiral gas channel is communicated with external air. The reuse system is simple in structure and low in manufacturing cost, the use ratio of latent heat energy of vaporization of liquefied natural gas is high, air resistance is increased by the spiral gas channel on the outer wall of the natural gas pressure reducing valve, gas-solid heat exchange coefficient is improved, the latent heat energy of vaporization of the liquefied natural gas is more efficiently used, so that a cabin is energy-saving and environment-friendly, the cabin temperature can be reduced as low-temperature air is led into the cabin, goods and materials can be kept fresh as the low-temperature air is led into a storage warehouse, energy consumption of a refrigerator carried by the boat is reduced, the low-temperature air is led into the cabin and can assist an air conditioner in cooling in hot weather, and the power and energy consumption of the air conditioner can be reduced.
