Industry information

Hot piece of hair heat pipe is widely used in many modern computer system, in the computer system, the increasing power requirements and the resulting heat increase lead to higher requirements for the cooling system. Usually, the heat pipe is used to heat from escaping through the radiator to the CPU and GPU components in the environment. Fever piece of hair heat pipe is widely used to heat the water application combined with vacuum tube solar collector arrays of solar thermal applications.

 

In these applications, the distilled water is usually used as the heat transfer fluid in the vacuum glass tube, and is located in the sealing tube, the sealing tube in the face of the sun. Personal absorber tube solar hot water application of the vacuum tube collector can provide up to 40% of the efficiency, compared with the traditional "flat plate solar collector". This is mainly due to the tube of convection and conduction heat loss due to slower, vacuum pipeline system is relatively low efficiency because "compared with" tablet ".

 

Collector plate collector has a large aperture and absorb more solar energy per unit area. Hot piece of hair heat pipe collector is reduced to a vacuum antifreeze additive is added to help slow the demand of heat loss. But under freezing temperature heat transfer fluid for a long time will still be frozen, prevention measures must be taken to ensure that the coolant will not damage the design of the vacuum tube. Design of the solar water heater with special additives to prevent frost to - more than 3 ° C, and is used to heat the water in Antarctica.

 

Heat pipe must be adjusted to a specific cooling conditions. Hot piece of hair heat pipe material, size and the choice of coolant all play a role in heat pipe, and under the optimum temperature. When heated above a certain temperature, all the working fluid in the tube will evaporate, and condensation process won't happen again.

Under such circumstances, only through the conductors of the solid metal shell can effectively reduce the thermal conductivity of the thermal pipe. Because most of the heat pipe by copper (metal) with high thermal conductivity, so overheating tube usually will continue to about 1/80 of the original thermal conductivity for heating. In addition, when the temperature falls below a specific temperature, working fluid will not occur, and thermal conductivity decreases as solid metal case.

 

Choose one of the key criteria of working fluid is applied required working temperature range. The lower temperature usually happen in a couple of degrees above the freezing point of working fluid. Due to the limitation of material, most manufacturer can be made not less than 3 mm diameter of the traditional heat pipe (although can produce 1.6 mm wafer).

 

Has been experimented on the micro heat pipe, the heat pipe using tube with sharp edges, such as triangle or lozenge tube. In these cases, the sharp edges by capillary action transmission fluid, therefore do not need the wick.
