Technical field
The present invention relates to a kind of hot pressing conversion temperature-uniforming plate, it is installed in radiator, improves the temperature uniforming heat radiation efficiency of radiator.
Also invention further relates to the manufacture craft of radiator temperature uniforming heat radiation method, radiating subassembly and radiating subassembly.
Background technology
With the made rapid progress of electrical technology, the appearance and size of electric equipment power device is less and less, power density is got over
Come higher, corresponding radiating heat flow density is also lifted therewith, radiating to radiator and change the requirement more and more higher of effect efficiency.Often
The radiator seen improves radiating and the mode of heat exchange efficiency mainly arrangement heat pipe or the temperature-uniforming plate in radiator, and two ways is equal
It is that external structure is used as by body or plate housing, inner hollow chamber is formed with relative, is elongated extension for heat pipe
Single spatial shape, temperature-uniforming plate then extend the spatial shape for expanding for planar, and the hollow chamber is vacuumized and a work is injected
Make liquid, with using the working solution thermal evaporation can be received to be condensed into the phase transformation of liquid characteristic repeatedly again, reach the work(for accelerating radiating efficiency
Energy.
But install the heat spreader structures of heat pipe or temperature-uniforming plate additional, still find there are problems that in practical application experience
The form flowed in rightabout in same section of space with the gas flow paths position of evaporation with scarce disadvantage, such as its liquid, it is past
Toward easily cause during the flowing of gas and liquid because moving-wire is collided with each other act mutually support, each other flow efficiency mutual subtract
Weak situation；, then for example, in the radiator for being disposed with heat pipe, a heat pipe part is located at power device bottom, also may extend to
Other positions of radiator, the problem for existing is that heat pipe need to ensure to be brought into close contact with radiator, does not have otherwise and answers effective anti-
And thermal resistance is increased, its technological requirement is higher；And the heat pipe limited amount that power device bottom can be arranged, thermal conductivity factor cannot
The level of heat pipe is reached, its linear temperature gradient is up to 85k/（m.kW）More than, although uniform temperature compares common radiator structure
Make moderate progress, but its radiating efficiency need to be improved.Also it is exactly, it is foregoing to be disposed with heat pipe or the radiator of temperature-uniforming plate its liquid
It with horizontal operating state is consideration that the flowing of body and gas is, it is apparent that being not particularly suited for being stood to guiding heat radiation
On power device（Such as the hanger of pendent lamp）, it can be seen that, its samming heat-exchange performance of existing radiator and to power device setting side
To adaptability need to be improved, analyzed based on more than, be the demand for adapting to the radiating of high power density device, it is necessary to develop one
Kind of samming heat-exchange performance is higher and radiating element that do not influenceed by power device setting direction.
The content of the invention
The hot pressing conversion temperature-uniforming plate that the present invention is provided, uniform temperature is splendid, the samming for that can improve radiator in radiator
Heat exchange efficiency, meets the radiating requirements of high power density device.The present invention also provides radiator temperature uniforming heat radiation method, radiating subassembly

Specific embodiment
1 to 4 pair of embodiments of the invention elaborates below in conjunction with the accompanying drawings.
Temperature-uniforming plate is changed in hot pressing, including metal material temperature-uniforming plate body 1, have in described temperature-uniforming plate body 1 uniform
Insertion stream 11 inside distribution and insertion temperature-uniforming plate body 1, fills cooling liquid 2, and cooling in described insertion stream 11
Liquid 2 is sealed in insertion stream 11.
As can be seen that temperature-uniforming plate body 1 has insertion stream 11 from Fig. 1 and Fig. 2, cooling is filled in insertion stream 11
Liquid 2, and cooling liquid 2 is sealed in insertion stream 11, when the local heating of temperature-uniforming plate body 1, local coolant of being heated
Body 2 heats up, but because the liquid 2 that has been cooled of insertion stream 11 takes, does not have the gas of cooling liquid 2 or the gasification of cooling liquid 2
The space of flowing, therefore because the limitation in space, cooling liquid 2 cannot be gasified when heating up, Local cooling liquid can only be directed at
The hydraulic pressure increase of body, forms pressure wave, along insertion stream 11 from the whole cooling liquid of local cooling liquid transmission, cooling
The heat that liquid 2 absorbs is distributed on whole hot pressing conversion temperature-uniforming plate with the transmission of pressure wave, so that real heat and pressure wave
Lasting conversion, pressure conversion temperature-uniforming plate heat transfer efficiency it is high, resistive properties are low, hot pressing conversion temperature-uniforming plate each position the temperature difference contracting
Small, uniform temperature is splendid, and samming heat exchange efficiency is high.
Wherein, the volume of described insertion stream 11 is not less than the 60% of the volume of temperature-uniforming plate body 1, the appearance of insertion stream 11
