Description
Technical field
The invention belongs to heat pipe field more particularly to a kind of loop circuit heat pipes.
Background technique
Hot pipe technique is George Ge Luofo of U.S. Los Alamos (Los Alamos) National Laboratory in 1963
One kind of (George Grover) invention is known as the heat transfer element of " heat pipe ", it takes full advantage of heat-conduction principle and phase transformation is situated between
The heat of thermal objects is transmitted to outside heat source rapidly by the quick thermal transport property of matter through heat pipe, and the capacity of heat transmission is more than to appoint
The capacity of heat transmission of what known metal.
The industries such as aerospace, military project were widely used in front of hot pipe technique, since being introduced into radiator manufacturing, so that
People change the mentality of designing of traditional heat sinks, get rid of the list for obtaining more preferable heat dissipation effect by high air quantity motor merely
One radiating mode makes radiator obtain satisfied heat transfer effect using hot pipe technique, opens heat dissipation industry new world.At present
Heat pipe is widely used in various heat exchange equipments, including nuclear power field, such as the UTILIZATION OF VESIDUAL HEAT IN of nuclear power etc..
On the one hand, heat pipe is in evaporation process, inevitably in carrying of liquids to tedge, simultaneously as condensation end
Exothermic condensation so that liquid also inevitably enters tedge, so that tedge there are liquid in condensation end
Interior fluid is liquid-vapor mixture, while heat pipe in the process of running can be because of the on-condensible gas of aging generation, on-condensible gas one
As rise to the condensation end on heat pipe top, the presence of on-condensible gas leads to the pressure increase in condensation end of heat pipe, and pressure makes
Flowing in the upward riser of liquid.Greatly affect the efficiency of heat exchange.
On the other hand, condensation this section of collector, because the space of this section becomes larger suddenly, space are exported to from tedge
Variation will lead to quickly flowing upwards out and assemble for gas, therefore spatial variations will lead to the vapour phase (vapour group) of aggregation from tedge
Position enters condensation collector, and due to gas (vapour) liquid density contrast, air mass leaves adapter tube position and will move rapidly upward, and air mass is former empty
Between position the liquid of wall surface is pushed away by air mass while will also spring back and hit wall surface rapidly, formed impingement phenomenon.Gas (vapour) liquid phase
More discontinuous, air mass aggregation is bigger, and Impact energy is bigger.Impingement phenomenon will cause biggish noise vibration and mechanical shock, right
Equipment damages.
The present inventor also devises a variety of heat-pipe apparatus to solve the above problems, such as multitube in applying in front, but
It is that such device is found in operation, because being to be closely linked between pipe, the sky that is formed between three root canals
Between A it is relatively small because the convex arc that space A is three root canals is formed, most of area stenosis of space A will cause stream
Body is difficult to enter through, and causes fluid short, to affect the heat exchange of fluid, can not play the role of good current stabilization.Simultaneously
Because more root canal subgroups of above structure are combined, manufacture is difficult.Such as 2017102671998 structures again, although the structure
It solves fluid short phenomenon, but there are problems that circulation area is substantially reduced, lead to the increase of flow resistance.Again for example
2017102949490 annular and separation device, separating device uses ring structure in ring structure, leads to separating device on the whole
Annular space separates unevenly in the circumferential, and because there are ring structure so that the position of four angles of annular space occur it is small
In 90 degree of acute angle, this, which will lead to, has fluid flowing short circuit in the acute angle portion less than 90 degree.

Preferably, the cross section of the tedge 3 is square.
Preferably, along the direction that fluid flows, the caliber of tedge 3 constantly increases.Main cause is as follows: 1) leading to
Cross the caliber for increasing tedge, it is possible to reduce the resistance of flowing, so that the steam for rising in-tube evaporation constantly increases towards caliber
The direction movement added, to further promote circulating for loop circuit heat pipe.2) because of the continuous flowing with fluid, liquid
It is constantly evaporated in tedge, so that steam volume is increasing, pressure is also increasing, therefore by increasing caliber
Meet the variation of ever-increasing steam volume and pressure, so that pressure is evenly distributed on the whole.3) pass through tedge

(H), i.e. S is using height H as the function of variable, and S ' is the first order derivative of S, meets following require:
S'<0；
Main cause is that carrier's liquid is understood in uphill process because of the steam in tedge, in uphill process, on
Riser is constantly heated, and causes the steam in biphase gas and liquid flow more and more, because the vapour phase in stream-liquid two-phase flow is more and more,
Exchange capability of heat in tedge can increase with vapour phase and weaken relatively, and vibration and its noise also can be continuous with vapour phase increase
Increase.Therefore the distance between the adjacent separating device for needing to be arranged is shorter and shorter.
In addition, upper header or condensation this section of collector are exported to from tedge, because the space of this section becomes larger suddenly,
The variation in space will lead to quickly flowing upwards out and assemble for gas, thus spatial variations will lead to the vapour phase (vapour group) of aggregation from
Tedge position enters condensation collector, and due to gas (vapour) liquid density contrast, air mass leaves adapter tube position and will move rapidly upward, and gas
The former spatial position of group pushes away the liquid of wall surface by air mass while will also spring back and hit wall surface rapidly, forms impingement phenomenon.Gas
(vapour) liquid phase is more discontinuous, and air mass aggregation is bigger, and water hammer energy is bigger.Impingement phenomenon will cause biggish noise vibration and machinery
Impact, damages equipment.Therefore in order to avoid the generation of this phenomenon, between the adjacent separating device being arranged at this time away from
From shorter and shorter, to constantly separate gas phase and liquid phase in fluid delivery process, thus reduce to the full extent vibration and
Noise.
