摘要： A fan logic evaluation device and method thereof for improving the logic evaluation of a fan. Specifically, a fan logic evaluation device is provided by first installing a fan, which corresponds to a set of parameters, in a wind tunnel device. A computer then performs a logic evaluation to convert the set of parameters into an evaluated pressure-flow curve and a measured pressure-flow curve by measuring the fan's operating conditions with the wind tunnel device. The computer further performs a logic modification to correct the logic evaluation to obtain a logic evaluation modification. The logic evaluation is then replaced by the logic evaluation modification. Finally, the above process is repeated with the same fan or a different fan.

摘要： A method to measure the transient thermal diffusivity performance of a heat dissipation module by selecting two measurement points on the surface of the heat dissipation module, and locating the two measurement points at the same side of the thermal center point but different distances, and measuring the temperature of the two measurement points separately and using first equation which is the analytical solution of the energy equation. After calculating the first equation, second and third equations are used to find M. The distance X1 between M and the first measurement point and temperature T1 at a moment of transient state are also inserted into the first equation to obtain the value of the thermal diffusivity coefficient α, which represents the transient thermal diffusivity performance for the heat dissipation module.

摘要： A thermal diffusivity performance measurement system is configured to measure a temperature of a pillar. The thermal diffusivity performance measurement system has a temperature sensor and a calculation unit. The temperature sensor is disposed at the pillar and configured to measure the temperature of the pillar. The calculation unit is configured to calculate a ratio of heat conduction to convection intensity per unit conduction intensity and a dimensionless time based on the measuring results of the temperature sensor. The calculation unit is configured to introduce the ratio of the heat conduction to the convection intensity per unit conduction intensity and the dimensionless time into a first formula as following: θ ⁡ ( X , τ ) = cosh ⁡ ( M - MX ) ⁢ sech ⁡ ( M ) + ∑ n = 1 N ⁢ ⁢ - 2 ⁢ λ n M 2 + λ n 2 ⁢ sin ⁡ ( λ n ⁢ X ) ⁢ e - ( M 2 + λ n 2 ) ⁢ τ The calculation unit calculates a temperature predictive model after the first formula is solved.

摘要： A thermal diffusivity performance measurement system is configured to measure a temperature of a pillar. The thermal diffusivity performance measurement system has a heater, a temperature sensor and a calculation unit. The heater is configured to heat the pillar. The temperature sensor is disposed at the pillar and configured to measure the temperature of the pillar. The calculation unit is connected to temperature sensor. The calculation unit is configured to calculate a ratio of heat conduction to convection intensity per unit conduction intensity and a dimensionless time based on the measuring results of the temperature sensor. The calculation unit is configured to introduce the ratio of the heat conduction to the convection intensity per unit conduction intensity and the dimensionless time into a first formula as following: θ  ( X , τ ) = cosh  ( M - MX )  sech  ( M ) + ∑ n = 1 N   - 2  λ n M 2 + λ n 2  sin  ( λ n  X )  e - ( M 2 + λ n 2 )  τ The calculation unit calculates a temperature predictive model after the first formula is solved. The beneficial effects of the present invention are that the thermal diffusivity performance of the pillar can be predicted by using a simple pillar temperature control measuring device to measure an instantaneous temperature and a steady-state temperature.
