Description

Method, device, equipment and storage medium for determining optimal value of heat dissipation parameter Technical Field The present application relates to the field of heat dissipation technologies, and in particular, to a method and apparatus for determining an optimal value of a heat dissipation parameter, a computer device, and a storage medium. Background In the field of heat dissipation technology, the heat generation problem of electronic devices is getting more and more severe with the increase of power. For example, one heat dissipation method is to first conduct heat of a heat generating device of an electronic device to a heat sink, and a fan can perform a heat dissipation operation against the heat sink to take away heat generated by the electronic device. In the current process of designing a heat dissipation module, a technician selects the specification of the heat dissipation module according to experience, performs proofing to obtain a sample, tests the sample to determine whether the sample meets the design requirement, and if not, needs to be re-selected and re-tested. Therefore, a large number of tests are needed to design the heat radiation module meeting the design requirement, a large number of test resources are occupied, the test period is long, and the cost for producing the heat radiation module is high. Disclosure of Invention The application provides a method, a device, computer equipment, a storage medium and a program product for determining an optimal value of a heat dissipation parameter, which are used for solving the problem of higher cost for producing a heat dissipation module. The application provides a method for determining an optimal value of a heat dissipation parameter, which comprises the following steps: Acquiring a three-dimensional model of a heat radiation module, constraint conditions of heat radiation parameters, a pre-constructed optimizing model, at least one heat radiation simulation model and boundary conditions corresponding to the at least one heat radiation simulation model respectively; generating a plurality of simulation conditions according to constraint conditions of the heat dissipation parameters; According to the three-dimensional model, at least one heat dissipation simulation model, boundary conditions corresponding to the at least one heat dissipation simulation model and the plurality of simulation conditions, executing heat dissipation simulation operation to obtain characterization information of heat dissipation performance indexes of the heat dissipation module under the plurality of simulation conditions; determining a mapping relation between the heat radiation performance index and the heat radiation parameter according to the plurality of simulation conditions and the characterization information of the heat radiation performance index of the heat radiation module under the plurality of simulation conditions; and determining the optimal value of the heat dissipation parameter of the heat dissipation module according to the constraint condition, the optimizing model and the mapping relation. According to the method for determining the optimal value of the heat dissipation parameter, the mapping relation between the heat dissipation parameter and the heat dissipation performance index can be determined through simulation operation, accordingly, the optimal value of the heat dissipation parameter can be determined within the range of constraint conditions by using the optimizing model based on the mapping relation, and therefore the optimal heat dissipation performance of the heat dissipation module can be determined under what value of the heat dissipation parameter. In the related art, after performing a simulation operation, a technician selects a heat dissipation parameter according to a simulation result, performs a proofing based on the selected heat dissipation parameter, and performs a retest. The design process and the test process need a great deal of hardware cost and time cost, and the heat radiation module meeting the design requirement can be finally determined only through multiple design and multiple tests. After the simulation operation is completed, the scheme firstly generates a mapping relation based on the simulation result, then carries out optimizing operation, determines the optimal value of the heat dissipation parameter, and further carries out proofing based on the optimal value of the heat dissipation parameter. Therefore, compared with manual selection, the optimal value of the more reasonable and accurate heat dissipation parameter can be selected through mathematical calculation, the number of times of proofing and testing can be greatly reduced, and the hardware cost and the time cost of producing the heat dissipation module can be reduced. And compared with the wasted resources of proofing and testing, the scheme only needs to occupy part of computing resources. Furthermore, the heat dissipation parame
