The heat dissipation principle of the radiator

release time:2014-07-29 11:18:00  Views: 548

The heat dissipation principle of the radiator:


When the temperature of the object and the outside world are not consistent, there will be heat conversion. The way of heat transmission: conduction (Conduction), convection (Convection), radiation (Radiation). The speed of conversion is the smaller specific heat The heat transfer rate is faster. Under the law of conservation of energy, the average heat energy will flow from high temperature to low temperature, and will not stop until the conduction effect is fully balanced. The coefficient of heat conduction: copper (385W/m℃)> water (0.556 W/m℃)>air (0.024W/m℃), metal>liquid>gas. When the two ends of the substance exist at different temperatures, as shown in the figure below:


The heat transfer between the flowing fluid of different temperatures and a fixed surface. The surface of the object (molecular diffusion) vs. away from the surface of the object (the overall movement of the fluid). The heat flow leaving the skin surface will warm the surrounding air, when the air temperature on the skin surface increases When the time, the density of the air also decreases. When the density is reduced, the ``hot'' air will rise, and the ``cold'' air will come in to make up for it, forming a flow of air. At the same time, it also takes away the heat and forms a convection phenomenon, so the skin feels around It's cold. As shown below:


Our body will radiate heat energy (thermal radiation-electromagnetic waves) to the surrounding environment, and the surrounding environment will also radiate electromagnetic waves for your body to absorb. Therefore, when the environment around you is at an extremely high or low temperature, thermal radiation It has become the main factor affecting the change of heat. In other words, heat is not conducted by objects, nor carried by liquids or gases, but is directly spread to various places by heat sources. The solar heat system is transmitted to the earth by radiation. The heat dissipation we use The system has always been unable to escape the principles of these three thermal energy conversions, that is, the use of heat conduction (Conduction), heat convection (Convection), and heat radiation (Radiation) to convert the computer CPU and other parts that need heat dissipation to convert heat energy into Other energy consumption is directly dispersed in the air during the conversion process, and achieves the ideal temperature we expect, so that the machine can run smoothly and safely, without other expected failures and damage.
