The heat exchanger solves the deficiencies of the heat exchange unit of the prior low-temperature heat pipe; the structure is as follows: the heat exchanger comprises an outer shell; a heat exchanger partition board is arranged in the outer shell, to divide the outer shell into a cold runner and a hot runner; the heat exchanger partition board is provided with a plurality of heat pipe retaining rings; the oscillating-flow heat pipe goes through the heat pipe retaining rings, with one end in the cold runner and the other end in the hot runner. The heat exchanger of the heat pipe can work normally at quite low temperature, keep quite high heat transfer coefficient, has low manufacturing cost, is convenient to be installed and safe to be used.
Description
Technical field
The utility model relates to a kind of oscillating flow heat pipe heat exchanger, belongs to the heat exchange field.
Background technology
At present operating temperature is lower than 160 ℃ low-temperature heat exchange device becomes the urgent problem in heat energy field.Industries such as oil, chemical industry, the energy and the drying of wood produce and give off a large amount of cryogens (gas and liquid), wherein contain a large amount of low-quality heat energy, because the temperature of this scope is lower, cause the heat transfer coefficient of corresponding heat utilization device generally lower, so this a large amount of low-quality heat energy is difficult to be used in both economical mode.Utilize heat-tube heat exchanger to carry out energy recovery and utilization mostly in the industry at present.But present common heat-pipe elements is as gravity assisted heat pipe, super heat-conductive pipe etc., because manufacturing cost and problems such as ease of use, security are used to promote to be subjected to certain limitation.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the deficiency of existing Cryo Heat Tube heat-exchanger rig, a kind of oscillating flow heat pipe heat exchanger is provided, this heat exchanger not only can be kept higher heat transfer coefficient in the heat transfer process of low temperature environment (50～160 ℃), and the conventional relatively heat pipe of manufacturing cost is cheap, easy to install.
For achieving the above object, the utility model adopts following technical scheme:
A kind of oscillating flow heat pipe heat exchanger, it comprises shell, described enclosure is provided with the heat exchanger dividing plate, and shell is divided into cold runner and hot flow path; Be provided with several heat pipe retainer plates on the heat exchanger dividing plate, oscillating flow heat pipe passes the heat pipe retainer plate, and an end is in cold runner, and the other end is at hot flow path.
Described oscillating flow heat pipe is snakelike sealing tubule bundle.
Described heat pipe retainer plate is connected on the heat exchanger dividing plate removably.
The utility model adopts oscillating flow heat pipe as heat exchange element.In outer cover of heat exchanger, oscillating flow heat pipe, heat pipe retainer plate, heat exchanger dividing plate connect, and the oscillating flow heat pipe tube bank is connected on the retainer plate, and retainer plate is dismountable the connection with dividing plate.Adopt oscillating flow heat pipe as heat exchange element, according to concrete serviceability temperature, inside heat pipe only need keep certain vacuum and charge into working media, and good seal gets final product then, does not need to install the needed imbibition core of conventional heat pipe.Middle the tightening of oscillating flow heat pipe is connected on the heat pipe retainer plate, and the heat pipe retainer plate is connected on the heat exchanger dividing plate removably, is convenient to the replacing and the dismounting of heat pipe.
Oscillating flow heat pipe is called pulsating heat pipe again, and its relies on the rapid vaporization-condensation process of interior media to conduct heat, thereby the heat transfer coefficient of oscillating flow heat pipe is significantly raise (for tens times even tens times of general heat pipe).Therefore utilize oscillating flow heat pipe very big as the heat exchanger heat transfer coefficient of heat exchange element, especially heat exchanger still can guarantee enough heat transfer coefficients in 50～160 ℃ temperature range, and this advantage makes oscillating flow heat pipe with the obvious advantage aspect low-temperature heat exchange; Manufacturing of oscillating flow heat pipe heat exchanger and installation cost are also cheap than general heat pipe heat exchanger.Can in 50～160 ℃ low temperature range, carry out the heat exchange of gas.Aspect the waste heat recovery of cryogenic gas special advantages is being arranged, for example the waste heat recovery of drying of wood tail gas.
The beneficial effects of the utility model are that heat exchange of heat pipe can be kept higher heat transfer coefficient in operate as normal under the lower temperature conditions, and low cost of manufacture, and is easy for installation safe in utilization.

Fig. 2 is the oscillating flow heat pipe schematic diagram;
Fig. 3 is the oscillating flow heat pipe bundle schematic diagram after adding retainer plate and tightening.
Wherein, 1. shell, 2. heat exchanger dividing plate, 3. oscillating flow heat pipe, 4. heat pipe retainer plate.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, Fig. 3, shell 1 inside is provided with heat exchanger dividing plate 2, and shell 1 is divided into the cold runner on top and the hot flow path of bottom, goes into cold fluid and hot fluid in it respectively together; Be provided with several heat pipe retainer plates 4 on heat exchanger dividing plate 2, oscillating flow heat pipe 3 passes heat pipe retainer plate 4, one ends in cold runner, and the other end is at hot flow path.Heat pipe retainer plate 4 is connected on the heat exchanger dividing plate 2 removably.Under this structure, cold and hot fluid all flows through oscillating flow heat pipe 3 outsides, carries out heat exchange by oscillating flow heat pipe.According to the structure of flow rate of fluid and hot and cold runner, can in runner, add deflection plate.(can with reference to the correlation criterion of conventional design of heat exchanger)
Among Fig. 2, oscillating flow heat pipe 3 is snakelike sealing tubule bundle, and the centre can bundle so that fixing, and inside heat pipe is kept the certain vacuum degree, and charges into a certain amount of working media, as water, ethanol etc.
Owing to show the tension force effect, the working media that the charges into situation that formation fluid column, gas column replace in pipe.Because inside heat pipe has been kept certain vacuum, the boiling point of inner working media is than low under the condition of normal pressure, as long as the heat pipe hot junction is heated to uniform temperature, the intraluminal fluid post will be vaporized rapidly, expands; Flow to the heat pipe cold junction, temperature reduces, and working media is condensation rapidly again.Vaporization---this violent phase transformation of condensation has guaranteed that oscillating flow heat pipe itself can have the higher coefficient of heat transfer.Experimental result shows: be filled with 50% R142b, the glass tubular type oscillating heat pipe that internal diameter is 0.5mm, the heat flow density of transmission can reach 1000W/cm when vertically working
2, be significantly higher than conventional wick heat pipe heat flow density (50W/cm
2).
Oscillating flow heat pipe: according to concrete heat exchange requirement, select length and internal diameter (can form capillary with the working media in the pipe, metal thin tube (metal tube is convenient to processing and is suitable as the heat exchange material) and the interior working media (water, ethanol, acetone, freon etc.) of pipe that general ips 1～5mm) is suitable, curve closed coiled pipe, reserve the mouth of pipe pipe is extracted into after certain vacuum (1 * 10
-1Pa～1 * 10
-2Pa), charge into working media, liquid filled ratio is 40%～70%, then with ferrule, keeps pipe air tight.
