Abstract

The invention discloses a manufacturing method of a hard disk heat dissipation model calibration device. The upper cover of the hard disk to be calibrated is removed, and the size of the hard disk storage disk is measured; the storage disk and the magnetic head are removed, and the coating around the motor stator is removed; Heat-resistant resistors, the heat-resistant resistors are connected in series; measure the total resistance value of the heat-resistant resistors; extend the wires at both ends of the series-connected heat-resistant resistors out of the hard disk body, and assemble the hard disk upper cover. The present invention also provides a method for calibrating a heat dissipation model of a hard disk. The above-mentioned device for calibrating a heat dissipation model of a hard disk is used to measure and calculate the average thermal resistance of the calibration device, and to calibrate the thermal conductivity parameter K of the hard disk. The invention realizes the precise setting of the parameters of each part of the hard disk, and can obtain a calibrated hard disk heat dissipation simulation model. The model is extremely accurate, and can replace the real hard disk to perform heating tests under different working conditions, reducing the use of the hard disk in the real system. The incoming material consumption provides solid data support for the system heat dissipation design.

Description

technical field [0001] The invention relates to the field of server heat dissipation simulation, in particular to a manufacturing and calibration method of a hard disk heat dissipation model calibration device. Background technique [0002] In the server cooling simulation work, the hard disk is an important part to establish a cooling simulation model. The model is generally obtained according to the size and material of the hard disk, and the properties such as density, thermal conductivity and power consumption of all components need to be input. [0003] When doing a simulation, the simulation parameters are usually set according to the inherent properties of the material. The heat dissipation simulation method for the hard disk is to obtain the overall size of the hard disk from the hard disk manufacturer, then build the entire hard disk into a simple block, and attach the thermal conductivity obtained from the manufacturer to this block.

[0004] However, in actual production, due to the influence of factors such as material composition, process parameters, preparation methods and impurities, even for the same material, the inherent properties of different batches of materials from different manufacturers will be different. Therefore, according to the material The inherent properties set the simulation parameters, and the simulation made may have certain deviations

At the same time, the power consumption of the hard disk will also have different differences in actual use, so the parameter setting of the power consumption in the simulation model will also affect the accuracy of the simulation
