Superiority of the present utility model is tangible.In above-mentioned high-efficiency heat transfer device, as long as hot and cold chamber exists the temperature difference, then can produce the phase transformation that makes thermal medium, be accompanied by the latent heat exchange, cause high efficient.And this device does not need motor, compressor and power set, and simple structure is with low cost, is easy to install, and reliable, operating noise is little, and heat transfer efficiency is high.Evidence economic benefit of the present utility model is very considerable.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is a high-efficiency heat transfer device schematic diagram of the present utility model;
Fig. 2 is a check valve amplification profile among Fig. 1;
Fig. 3 is the amplification profile of nozzle among Fig. 1;
In the accompanying drawing, same parts is represented with identical label.
Label 10 representatives whole vapour-liquid of the present utility model shunting high-efficiency heat transfer device among Fig. 1.Label 1,2 is represented the heating chamber and the cooling chamber of heat transfer unit (HTU) respectively, and its form can be the thick light pipe of container, linker or the coiling of all styles of, and 3,4 for connecting heating chamber 1, and the fluid passage of cooling chamber 2 and gas passage are generally straight light pipe.Heating chamber 1, cooling chamber 2, can make by high conductivity material such as copper.
In the junction of heating chamber 1 and fluid passage 3, provide a check valve, provide a nozzle 5 in the junction of heating chamber and gas passage 4.
Fig. 2 is the cutaway view of check valve 6.It is configured to, on a cylindrical copper billet 21, provide 22,23, balls 24 of through hole of two different-diameters to place therebetween, " seat " is on the shoulder 25 between two holes 22,23, shoulder 25 is an arcwall face, its underpart and ball contact portion form sealing surface, and the sealing face can push shoulder 25 formation of copper post by steel ball.A spacer pin 26 is equipped with in the top of ball 24,26 also can make spacing protruding form in another embodiment, promptly is equivalent to pin 26 mid portions are cut off, and only stays two and protrudes the end, to limit the displacement of ball 24.
What deserves to be explained is, the size of ball 24 and and spacer pin between distance, need according to different occasions, definite through testing, generally speaking, the size of ball is less than 30mm, and and spacer pin between distance less than 10mm.Ball is generally steel ball, also can adopt other hard materials such as glass to make.In installation, need make the valve 6 relative horizontal planes 5-45 ° of angle that be inclined upwardly, so that the ball 24 of valve 6 is in closed condition before shoulder is moving.
Fig. 3 is the cutaway view of nozzle 5: it is configured to, and the through hole 31,33 of 2 different taperings is provided from both sides on a cylindrical copper billet, and the centre is a pore 32 that is communicated with.The tapering of arrival end through hole 31 is generally 30 °～180 °; And port of export through hole 33 is 12 °～60 °.The centre carefully also 32 can be generally below 1/2 of communicating pipes 4 internal diameter, its length L according to communicating pipe internal diameter and dielectric property respective change
1Be 3～5mm, entire length L
2Be 15～50mm.Charge into an amount of good fluidity in the heat transfer unit (HTU) 10, but the medium of phase transformation, as freon, alcohol, water, butane, pentane, azeotropic solution (R501, R502, R503, R504) etc.According to condition of work, application scenario, topping up ratio under the normal temperature is 20～80% for freon generally in this heat transfer unit (HTU), and after promptly aneroid was finished at normal temperatures, the liquid proportion of the heat transfer medium in the loop was 20～80%, and all the other exist with gaseous form.
The heating chamber of heat transfer unit (HTU) is positioned at the below of cooling chamber in vertical direction.When work, device heating chamber 1 is heated, and wherein liquid medium can absorb the heat vaporization, volumetric expansion, and pressure raises.Medium is subjected to stopping of one-way flow device 6 at the fluid passage mouth, and is subjected to the acceleration of nozzle during forward by nozzle 5, and momentum increases, and forms high velocity air.Outlet at nozzle realizes that further vapour, liquid separate, and rises at a high speed with the gas form, enters cooling chamber by the gas passage.Because cooling chamber 2 temperature are lower than the transformation temperature of medium, so medium becomes liquid state, emit latent heat, volume reduces simultaneously, and pressure descends.The liquid medium that accumulates in the cooling chamber flows under the influence of gravity into fluid passage 3, and at the fluid passage mouth of heating chamber, because the reverse barrier effect of one-way flow device makes gas be difficult to rush in fluid passage, has kept original low-pressure state in the fluid passage.Liquid in the cooling chamber constantly flows into fluid passage under the gravity effect, form the gravity post, and then has strengthened the power that liquid refluxes again, and this process constantly develops, and makes liquid medium be full of fluid passage, the gravitational pressure that forward flows on non-return device 6.
Vaporize by nozzle in the gas passage course of injection in the heating chamber medium, because the effect of inertia that gas flows, can occur instantaneous pressure in the heating chamber descends, liquid medium in the fluid passage is inhaled into heating chamber, make liquid medium constantly enter heating chamber by non-return device 6 at work, replenish the medium that is vaporized with intermittence, pulse mode.
Because the effect of nozzle and one-way flow device has formed between heating chamber and cooling chamber and has specialized in the passage that gas rises and liquid refluxes.
Working media is accompanied by the generation of latent heat by in the phase transformation of the liquid → vapour of heating chamber and cooling chamber and vapour → liquid and circulate, and this device has produced high heat transfer efficiency.In theory, as long as exist the temperature difference between heating chamber and the cooling chamber, just have above-mentioned heat transfer cycle process.
In above-mentioned example, dispose a gas passage and the parallel UNICOM of fluid passage between heating chamber and the cooling chamber, the gas passage is generally thick than fluid passage.Also can be walked abreast by many gas passages and many fluid passages and form, the gas passage will be more than fluid passage.Every steam passage will have a nozzle at least; Every fluid passage will have a non-return device at least, and flow direction is a heating chamber.
In above-mentioned example, because the use of nozzle, heated medium is between heating chamber and cooling chamber, under the jet-action of nozzle, realized the high speed preshoot, fully vaporization, guaranteed that in steam passage medium can be with the gaseous form flow at high speed, speed can reach the tens of rice of per second.So just eliminated the reverse backflow of liquid medium in steam passage in the cooling chamber, and system is started easily, operating pressure is low, noiselessness, and transmitting range is far away, and heat-transfer capability is big.Thereby avoided vapour in the conventional heat pipe, liquid to walk same passage, influenced each other, flowing velocity is slow, transmitting range is little, and biography can wait shortcoming less.
In the foregoing description, the shoulder 25 of valve 6 is an arcwall face, and obviously it also can make the conical surface etc., and its underpart squeezes out sealing surface; Ball 24 also can make the cone form.Being connected and realizing by welding between valve 6, nozzle 5 and fluid passage 3, the gas passage 4; Also can be by copper post 21 is put into pipeline, the tube wall at the contiguous copper post of extruding 21 two ends makes valve 6, nozzle 5 location.
In addition, because heating chamber 1 and cooling chamber 2 are the workspace, middle gas passage 4,3 transmitting effects of fluid passage are so often carry out with heat-barrier material in using.
