The Arctic Fox - Vulpes lagopus, lives in some of the most frigid extremes on the planet. Among its adaptations for cold survival are its deep, thick fur, a system of countercurrent heat exchange in the circulation of paws to retain core temperature, and a good supply of body fat. The fox has a low surface area to volume ratio, as evidenced by its generally rounded body shape, short muzzle and legs, and short, thick ears. This arctic fox is a resident of the Point Defiance Zoo and Aquarium.
In the photo, one of many ways animals regulate their body temperature is on display. The hippo is bathing in water in order to stay cool on a hot day. Bathing is an evaporative mechanism that many animals utilize. Additional ways animals control heat exchange with the environment include insulation, circulation, countercurrent heat exchange, evaporation, behavior, long-term behavior, and metabolism. The photo was taken at the Denver Zoo.

Coal, as a solid combustible organic rock, is known as black gold and industrial food. With the rapid development of coal processing depth and breadth, coal output has increased significantly, and the coal drying industry has also developed rapidly. The coal dryer has a good drying effect, can dry the moisture in the coal, is efficient and energy-saving, and has huge economic and social benefits.
1. The coal dryer adopts countercurrent conduction dehumidification, which reduces the repeated drying process, saves time, occupies a small area, consumes less electricity, saves energy and requires less investment.
2. During the drying process, the hot air moves forward from the tail, fully contacting the material, making full use of the heat transfer of heat conduction, convection and radiation, and saving energy.
3. The coal dryer equipment solves the problem of water vapor returning to the material after the system temperature drops in the same direction caused by the downstream dehumidification of the traditional dryer, which helps to improve the drying efficiency and drying effect.
4. The coal dryer directly transfers heat energy to the material, so that the moisture of the material evaporates in the cylinder, and the imported suction device extracts a large amount of moisture and wet air, which solves the fundamental problem of secondary pollution caused by dust discharge.
