Under the action of convex, triangle rubber flap and the angle of segment-shaped flick diaphragm axial angle θ become larger, as lotus petal type is beaten
It opens, segment-shaped flick diaphragm gas vent is opened.
The air pressure control water unit is made of reservoir chamber, vaporium, aqueduct, water filling non-return valve and inlet channel.Its
Middle vaporium is located at the top of air pressure control water unit, and reservoir chamber is located at the lower part of air pressure control water unit, and water filling non-return valve is located at gas
The top of voltage-controlled water unit, the bottom of air pressure control water unit are connected with aqueduct, and aqueduct is connected to air pressure control water unit, water guide
The other end of pipe by inlet channel on inlet end sealing cover non-return valve and air inlet connect.Air pressure control water unit can be inhaled
Certain radiator heat is received, water rapid evaporation in expanding chamber is conducive to, also, since temperature raises in air pressure control water unit
A certain amount of water vapour is formed in upper steam room, is increased the pressure in air pressure control water unit, is conducive to water and rapidly enters expansion
It is indoor；Furthermore the indoor initial pressure of expansion can also be increased；Finally, being raised and lowered with radiator temperature, air pressure control water list
Member can control into the amount for expanding indoor water.
When pressure is greater than atmospheric pressure in air pressure control water unit, the water filling non-return valve is closed, when air pressure control water unit
When interior pressure is less than atmospheric pressure, water filling non-return valve, which is opened, enters air, can be expanded using air when air pressure control water unit is anhydrous
Heat absorption.
Radiator working principle and the course of work of the present invention are as follows:
When power device work, the amount of heat of radiator absorption dynamometer part diverging.Multiple groups breathing in radiator
Temperature is quickly transmitted in expanding chamber and Heat Conduction Material with capillary function by unit.The liquid of air pressure control water unit discharge
Water and the gas of carrying, quickly spread in the Heat Conduction Material with capillary function through non-return valve and absorb heat, and water is gentle
Expansion is evaporated due to absorbing expanding chamber heat, makes to expand room pressure increase, since pressure increases PV=Rt under the conditions of waiting appearance
Heating degree increases, and accelerates gas rapid expanding, and wherein P is pressure, and V is volume, and R thermal coefficient, t is temperature.When pressure is greater than
When segment-shaped flick diaphragm Snapping Through point, segment-shaped flick diaphragm overturns from spill to convex and jumps, while segment-shaped jumps
The curved surface valve of center is opened, and the hot gas that the air-flow that segment-shaped flick diaphragm generates when jumping carries expanding chamber flows to same side
To quick discharge, the above process is also referred to as breathing unit exhalation process.The thermal current of breathing unit exhalation at this time makes the general ability that radiates again
Portion's gas expansion, gas density and air pressure drop are low, make radiator and peripheral gas directed flow, are formed " cold-hot air convection ",
Since air is extraordinary heat guard when static, be just able to achieve heat dissipation when only air flows, speed air flow with it is scattered
Heat is directly proportional, and flow velocity is faster, and heat dissipation is better.
When jumping overturning to convex from spill due to exhalation process segment-shaped flick diaphragm, segment-shaped flick diaphragm outer surface
Air is acted on, the gas of certain flow rate is generated, atmospheric pressure at expanding chamber gas vent is further decreased, thereby speeds up expansion
Indoor air-flow is quickly discharged, and also making to expand indoor pressure quickly reduces, and expansion intraventricular pressure is caused to be less than outside pressure by force, this
When non-return valve open, gas and a small amount of water sucking expanding chamber in.
It is determined by the design of segment-shaped flick diaphragm structure, when segment-shaped flick diaphragm changes to pole from spill to convex overturning
When limit degree, segment-shaped flick diaphragm knock-ons from convex to spill automatically to be overturn.When segment-shaped flick diaphragm is from convex to spill
It jumps in switching process, segment-shaped flick diaphragm inner surface acts on expansion indoor gas reverse compression, and non-return valve is closed.Work as ball
When scarce shape flick diaphragm reaches spill stable state, concave curved surface closes lotus flap-type curved surface valve, and gas pressure intensity is greater than in expanding chamber
The outer atmospheric pressure of expanding chamber, the above process are also referred to as breathing unit breathing process.Expansion intraventricular pressure is strong at this time are as follows: ambient atmosphere pressure
+ segment-shaped flick diaphragm knock-ons to expanding chamber gas compression pressure=expansion chamber pressure；
When inspiration to the indoor water of expansion and the expansion of aspiration heat of vaporization, increase expansion intraventricular pressure by force.It expands at this time
Indoor pressure are as follows: the rebound of the ambient atmosphere pressure+water evaporation bulbs of pressure+segment-shaped flick diaphragm to expanding chamber gas compression pressure=
Expand room pressure；
When segment-shaped flick diaphragm reaches Snapping Through point pressure, the indoor water evaporation bulbs of pressure are expanded are as follows: water steams
The bulbs of pressure=segment-shaped flick diaphragm Snapping Through point pressure-ambient atmosphere pressure-segment-shaped flick diaphragm rebound is sent out to expansion
Room gas compression pressure；
Segment-shaped flick diaphragm Snapping Through point pressure=expansion room pressure
It is placed in the air pressure control water unit of radiator side, since steam chamber pressure is directly proportional to radiator temperature, is dissipated
Hot device temperature is higher, and boil-off gas gets over multiple pressure Qiang Yue great, and thus the flow of air pressure control water unit output water is transmitted in steam chamber pressure
Under, the water provided to expanding chamber is more, and it is bigger to expand indoor vapour density, and it is more to absorb radiator temperature, the gas of discharge
Body flow is bigger, and heat dissipation effect is better.Such as human-body radiating, when environment temperature, which is greater than Human Physiology, perspires temperature spot, human body
It is radiated physiology course by evaporation of perspiration.Otherwise radiator temperature is lower, and the steam room pressure of air pressure control water unit is smaller, to
Expanding chamber exports the synchronous reduction of water, when radiator temperature reduces the steam room pressure and environmental pressure phase of air pressure control water unit
Deng supplying water stops, and radiator enters natural heat dissipation, enters in expanding chamber only air at this time.Thus heat transmission is greatly reduced
Water, while by rationally designing the vaporium amount of capacity in air pressure control water unit, it can also achieve the purpose that water conservation.
In order to guarantee that radiator efficiency reduces water consumption, radiator of the present invention is radiated by Four processes:
1, when radiator low temperature, radiator enters natural cooling process；
2, radiator temperature is stepped up, and air pressure control water unit coolant-temperature gage is synchronous to be increased, but air pressure control water unit vaporium
When interior pressure is not more than environmental pressure, expanding chamber only sucks air, and radiator heats expansion heat dissipation to air by thermal expansion room
Process；
3. in radiator temperature boost air pressure control water unit vaporium air-inflated pressure increase, expanding chamber suck air and
Water, radiator heat water and air by thermal expansion room, water and gas heat absorption evaporation expansion, when expansion chamber internal pressure reaches
When segment-shaped flick diaphragm Snapping Through point pressure, endothermic gas discharge heat dissipation in expanding chamber.Since air pressure control water unit is to swollen
Swollen room confluent is directly proportional to radiator temperature, and radiator temperature more hyperbar control water unit is bigger to expanding chamber confluent, instead
Radiator temperature more low pressure control water unit it is fewer to expanding chamber confluent；
4. radiator temperature reduces, the temperature of air pressure control water unit water is synchronous to reduce water supply stopping, and radiator enters to sky
Gas heating expansion heat dissipation, gradually arrives radiator natural cooling process；
Since heat dissipation capacity is related with water consumption, exothermic temperature, expansion chamber vol, capacity and gas flow rate, and gas stream
The pressure p of fast u and expanding chambermIt is related with lotus flap-type curved surface valve ventilation aperture area s, expand building volume VgSize and gas flow rate u
It is unrelated, and it is related with flow, and volume is bigger, and extraction flow is bigger, and the used time is longer.It is smaller to expand the smaller extraction flow of chamber vol, adds
The hot used time is shorter, and the frequency that journey was exhaled and be drawn through to completion respiration unit is higher；
Since radiator of the present invention is a kind of device that collection mechanical movement, air force and heat power combine, embody
The respective advantage of water cooling, air blast cooling, natural cooling out.Due to heat dissipation capacity WRWith expanding chamber discharge frequency F, radiator temperature Tc, when
Between length ts, water Lw, expansion building volume VgAnd segment-shaped flick diaphragm spinodal decomposition point pressure pmIt is related, so there is heat dissipation capacity WR:
WR=f (ts, Vg, Tc, Lw, p1, F)；Due to the pressure p of expanding chamber1It is discharged in segment-shaped flick diaphragm spinodal decomposition point, institute
It is equal to segment-shaped flick diaphragm unstability point pressure with the pressure of expanding chamber.
The invention has the characteristics that:
● catchment, force wind, natural heat dissipation: when expanding chamber sucks water, progress is evaporative cooling, the same water of this process
It is cold to radiate, when expanding chamber evaporates discharge gas process, natural environment heat dissipation is placed in nature with air blast cooling heat dissipation, radiator
It is cooling, collect respective advantage heat dissipation；
● in natural cooling, radiator temperature is lower than temperature control critical point, air pressure control water of the present invention, lotus valve curved surface valve, gas
Body inflatable membrane great-jump-forward radiator is using air heating expansion heat dissipation, when only radiator temperature is higher than temperature control critical point,
Just starting water evaporation heat dissipation, therefore water consumption is few；
● compared with same volume is natural air cooled, excess power is not consumed, heat-sinking capability is improved, it is close that power output can be improved
Degree；
● increase heat dissipation area；
● simple mechanical structure is used, high reliablity is at low cost.
