According to the method, the problem that the technical requirement caused by increasing of the appearance size, increasing of number of mechanical connectors, irregular distribution of hot connectors and the like of a novel returning satellite single-phase fluid loop heat collection board needs to be improved, and consequently, the heat collection problem to manufacturing and molding of the heat collection board is caused is solved.
Description
Technical field
The present invention relates to spacecraft Evolution of Thermal Control Technique field, be specifically related to a kind of distributed collecting plate forming method.
Background technology
Satellite collecting plate is a kind of special plate fin type heat exchanger, only one layer of heat exchanger channels, by upper and lower panel, leads
Flow fin, heat exchange fin, strip of paper used for sealing, bury block composition.Electronic equipment is arranged on the upper and lower panel surface of cold drawing, and working media is by connecing
Head, enters inside cold drawing, distributes through distributing fin, even into heat exchange fin, when taking away panel outer surface electronic device works
After the heat sent, temperature raises, and flows out from the joint of the other end.Working media after temperature rising flows after being re-cooled again
Enter cold drawing, constitute circulation.
Novel return satellite is to solve recovery capsule heat consumption to return a difficult problem for more than 10 times of satellite higher than tradition, makes at recovery capsule
With collecting plate collecting device heat.Novel return satellite recovery capsule collecting plate exists bigger with traditional single phase fluid circuit collecting plate
Difference, is mainly reflected in following several respects:

The half of plate area；
(2) mechanical interface: novel return satellite recovery capsule collecting plate, in order to assemble with satellite structure and equipment, sets in plate face
Counted more than 80 Φ 4～Φ 9 differ in size, skewness and the installing hole of hi-Fix requirement, and tradition one-way fluid returns
Road collecting plate its installing hole of correspondence single equipment is usually no more than 10, and is distributed for rectangle rule；
(3) hot interface: overall heat consumption about 200W electronic equipment is randomly distributed on novel return satellite recovery capsule collecting plate,
And tradition one-way fluid loop collecting plate correspondence single equipment, the former proposes higher to the thermal-arrest of isothermal plate and isothermalization design
Requirement；
(4) weight: novel return satellite is less than 10 kilograms owing to weight limits two pieces of 5mm thickness cold drawing gross weights, is phase
Same volume, trade mark aluminum half less than.
In a word, novel return satellite recovery capsule collecting plate is due to technology requirements such as overall dimensions, mechanical interface and hot interface
Raising, cause no small difficulty to the manufacture molding of collecting plate, use traditional method cannot ensure that novel heat collecting plate can
With satisfied use requirement, it is therefore necessary to grope brand-new forming method to ensure the manufacture molding of novel heat collecting plate.
