Understand for the ease of reader, the above method is illustrated below by specific example:
Step 1:It analyzes the high temperature heat sources such as battery in cabin and corresponding radiant heat is established to the radiant heat transfer amount of below deck equipment Flow database;
Step 1.1 analysis generates the high temperature heat source of radiant heating to below deck equipment and determines the temperature of high temperature heat source, usually The high temperature heat source that radiant heating is generated to below deck equipment is mainly battery, and the temperature of battery shock wave back casing is 350 DEG C.
Step 1.2 generates the grid that high temperature heat source calculates below deck equipment radiant heat transfer amount
The grid does not include the structured grid of high temperature heat source and below deck equipment, only includes the air-shed grid in cabin, is used for The ascent of analyzing radiation heat output, it is of less demanding to mesh quality, require nothing more than that grid transition is good, orthogonality is good.
Step 1.3 is carried out high temperature heat source and is calculated the radiant heat transfer amount of below deck equipment
There are two types of analysis methods:
(1) Fluent softwares are utilized, radiation heat-transfer model is opened, set temperature, the transmitting of high temperature heat source and below deck equipment Rate data, the net radiation hot-fluid (Radiation of below deck equipment when calculating the below deck equipment of high temperature heat source irradiation different temperatures Heat Flux), establish the database of below deck equipment wall surface (temperature, net radiation hot-fluid).
Temperature after battery shock wave is 350 DEG C, and below deck equipment temperature raising after by electromagnetic radiation judges that only electromagnetic radiation draws It plays device temperature and does not exceed 350 DEG C.Emissivity, the temperature data of battery and below deck equipment are set, carried out in cell irradiation cabin Device analysis obtains the net radiation hot-fluid (Radiation Heat Flux) of below deck equipment, establish below deck equipment wall surface (temperature, Net radiation hot-fluid) database when, selected equipment wall surface temperature is respectively 280K, 290K, 300K, 310K ... 650K.Due to Radiation equation and energy equation are restrained quickly, and the calculating time of each example only has more than ten seconds, radiation net radiation heat flow data library Total time-consuming is less than 1 hour.
(2) Fluent softwares are utilized, radiation heat-transfer model is opened, set temperature, the transmitting of high temperature heat source and below deck equipment Rate data, radiant heat flux (the Absorbed Radiation that below deck equipment absorbs when calculating high temperature heat source irradiation below deck equipment Flux)。
Since the rapid analysis method that this patent proposes does not need fine flow field, and the very difficult convergence of flow equation, It calculates and takes very much, in order to improve computational efficiency, flow equation need not be solved, only solve radiation patterns equation and heat transfer side Journey.
Step 2:Radiation, equipment self-heating and the heat transfer for considering high temperature heat source, analyze the temperature of below deck equipment.
Step 2.1 generates the heat transfer grid of below deck equipment
For analyzing below deck equipment heat transfer, it is desirable that grid transition is good, orthogonality is good.

The heat source of below deck equipment heating includes three parts:In cabin high temperature heat source to the radiant heating of below deck equipment, equipment from Body fever, air heat the heat conduction of below deck equipment.
By research, computational methods there are two types of the hot-fluids below deck equipment, the calculating knot of both analysis methods are loaded Fruit is consistent, and visual feelings are selected.
This patent uses the User Defined interface that Fluent softwares provide, and by writing, program will " load be set in cabin The language that calculating thinking, the computational methods of standby upper hot-fluid " are converted into Fluent identifications is embedded into software, controls entire calculate Process.
Two kinds of computational methods of " hot-fluid of the load below deck equipment " are as follows:
(1) hot-fluid of the load below deck equipment is:
Q(w/m2Net radiation hot-fluid (Radiation Heat Flux) of the)=high temperature heat source to below deck equipment
+ below deck equipment self-heating hot-fluid
+ air conduction hot-fluid
In its middle deck high temperature heat source to the net radiation hot-fluid (Radiation Heat Flux) of below deck equipment by step 1.3 First method obtains, and the User Defined interface provided using Fluent, bespoke program is by (temperature, net radiation hot-fluid) Database is loaded according to coordinate on equipment wall surface, and the net radiation hot-fluid of different moments can be by writing program to equipment wall surface temperature The biquadratic interpolation of degree obtains.
Below deck equipment itself hot-fluid is provided by equipment development unit.
Air conduction hot-fluid is obtained using the engineering method of one-dimensional linear heat transfer between high temperature heat source and below deck equipment wall surface.
(2) hot-fluid of the load below deck equipment is:
Q(w/m2Radiant heat flux (the Absorbed that below deck equipment absorbs when)=high temperature heat source irradiates below deck equipment Radiation Flux)
Self-heating hot-fluid in+cabin
+ air conduction hot-fluid
Since equipment itself high temperature is to the hot-fluid of external radiation
The radiant heat flux (Absorbed Radiation Flux) that wherein below deck equipment absorbs is by second of side of step 1.3 Method obtains, and the air conduction hot-fluid between high temperature heat source and below deck equipment wall surface is obtained using the engineering method of one-dimensional linear heat transfer , since the high temperature of equipment itself obtains (ε σ T to the hot-fluid of external radiation using grey-body radiation formula4)。
The User Defined interface provided using Fluent writes the language that the above thinking is transformed into Fluent identifications by program Speech load is in entire calculating process.
Step 3:It analyzes below deck equipment temperature and rises mechanism, propose the major measure of control below deck equipment Wen Sheng, to improve in cabin Foundation is instructed in environment proposition
Step 3.1 analyzes below deck equipment temperature and rises mechanism
Using the method for step 2, for only consideration high temperature heat source radiation, consideration high temperature heat source radiation+self-heating, examine Consider high temperature heat source radiation+self-heating+air conduction these three states, respectively the maximum temperature on analytical equipment surface.By right Than the maximum temperature on these three status devices surfaces, the principal element and secondary cause that cause equipment Wen Sheng are judged.Fig. 1 is different Inertial navigation under heat exchange approach and electric control box temperature.
It can find that electromagnetic radiation is the principal element for causing inertial navigation and electric control box overtemperature.
Step 3.2 proposes the major measure of control below deck equipment Wen Sheng, for improving below deck equipment environment
For the principal element and secondary cause for causing equipment Wen Sheng of 3.1 analyses, propose that control device Wen Sheng's is main Measure is limitation principal element, and then improves below deck equipment environment.
It is electromagnetic radiation usually to cause the principal element of equipment Wen Sheng, to improve thermal environment in cabin, it is ensured that below deck equipment is not Overtemperature need to take measures to reduce radiation of the battery to equipment, for example increase thermal baffle among battery and equipment.
