Analysis of the principle and function of ultra-thin cooling fan.clip fan company

　　Now, ultra-thin cooling fans are used in various fields of work to improve the work efficiency of the industry. So what is the principle of the ultra-thin cooling fan, maybe most people are not clear at the same time, then, let's introduce the purpose and working principle of the ultra-thin cooling fan in detail.

　　What is an ultra-thin cooling fan

　　Ultra-thin cooling fans (referred to as radiators, also known as cooling pipes) are the main equipment in heat exchange devices such as cooling air with refrigerant, heating air with heat medium, or recovering air waste heat with cold water. The air can be heated by feeding high temperature water, steam or high temperature heat transfer oil, and the air can be cooled by feeding salt water or low temperature water.

　　What is the purpose of the ultra-thin cooling fan

　　Ultra-thin cooling fans can be widely used in hot air heating, air conditioning, cooling, condensation, dehumidification, drying in various industries such as light industry, construction, machinery, textile, printing and dyeing, electronics, food, starch, medicine, metallurgy, painting and so on. Wait.

　　Introduction to the structure principle of ultra-thin cooling fan

　　The structure of the ultra-thin cooling fan is composed of a cooling exhaust pipe, an inlet and outlet header, and a frame. Among them, the heat dissipation pipe is composed of a heat dissipation pipe bundle, and the heat dissipation pipe is composed of a base pipe and a fin. The quality of the heat pipe determines the heat exchange effect, the arrangement of the heat pipe affects the air resistance, and the installation method of the heat pipe determines the ability to withstand temperature differences (thermal expansion and contraction). Commonly used radiator pipe installation methods: frame fixed type (SRZ type, SRL type, S type), frame support type (GL type, U type). Among them, the frame fixed type, the heat pipe is directly welded to the frame box, the result is simple, generally used for heating or refrigerant below 180 ℃; the frame support type, the heat pipe passes through the frame porous plate, and is welded with the connecting pipe (or elbow) , generally used for heating medium above 180 ℃. Commonly used heat pipe types: steel heat pipe (steel pipe wrapped around steel fins, hot-dip galvanized treatment), steel-aluminum composite heat pipe (steel pipe rolled with aluminum fins), copper heat pipe (copper pipe wrapped around copper fins, tin-lined treatment) ), copper-aluminum composite heat pipe (copper tube rolled with aluminum fins), stainless steel heat pipe (stainless steel tube around stainless steel fins, high-frequency welding). Among them, the steel heat pipe, hot-dip galvanizing is the key, which can fill the gap, stabilize the fins, efficient heat transfer, and efficient anti-corrosion; copper heat pipe, tin lining is the key.
