Description

A heat sink for miner's lamp

technical field

The utility model relates to a radiator used in a miner's lamp, which belongs to the field of miner's lamp cooling equipment.

Background technique

High bay lights are lamps used in the production and operation areas of factories and mines. In addition to various lighting lamps used in normal environments, high bay lights also have explosion-proof lights and anti-corrosion lights used in special environments. High bay lights are also used for Some large high-rise buildings.

Due to the high power of the existing industrial and mining lamps, large radiators are required to dissipate heat from the internal power supply and light source. However, this type of industrial and mining lamps all use heat transfer to dissipate heat, and the heat dissipation efficiency is still not ideal. Effective distribution accelerates the evaporation of the liquid inside the electrolytic capacitor on the power supply, shortens the service life of the high bay lamp, and increases the cost of equipment maintenance and repair.

At present, the natural convection radiators used in common industrial and mining lamps are mostly sunflower structures. This radiator uses the columnar structure in the middle to export the heat energy of the heat source, and then dissipates the heat into the air through the surrounding sheet structure. , by adjusting the overall height of the radiator to match light sources with different powers, it is more suitable for light sources with concentrated heat points. However, with the increase of the power of the lamp, the calorific value is greatly increased. Even if the volume of the radiator is continuously increased, the heat dissipation efficiency will become lower and lower, which cannot meet the heat dissipation requirements of high-power lamps. At the same time, the mass of the heat sink with this structure is relatively large, and there are certain potential safety hazards when it is suspended and installed.
