The way of heat transfer in the cooling fan
the way of heat transfer on the cooling fan has the following three kinds:
1. Heat conduction: substance itself or when contact, energy transfer is called a heat conduction, this is one of the most common way of heat transfer, such as: heat sink base and direct contact with the way take away heat is heat conduction.
2. Heat convection: refers to the flow of gas or liquid will go tropical way of heat transfer in the cooling system of automobile chassis more common is a cooling fan to drive the gas flow of forced convection cooling way. Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of cooling fans.
3. Thermal radiation: refers to rely on the radiation heat transfer, everyday is the most common form is the three kinds of xinyang radiation heat dissipation is not independent, these three cooling way is happening at the same time, work together.
such as ordinary water cooling fan, radiator, direct contact with the surface of the surface of the heat through heat conduction is passed to the heat sink, and a cooling fan to produce gas circulation of fin surface heat convection of heat away, face the flow of the air inside the case and by heat convection/chassis heat away until the chassis of the surrounding air, all at the same time part of the high temperature will occur on the surrounding parts of low temperature thermal radiation.
