Background technology
Oscillating flow heat pipe (Oscillating Heat Pipe, OHP) claim pulsating heat pipe, tortuous capillary heat pipe and selfexcited oscillating-flow heat pipe etc. again, at first propose by Japanese scholar Akachi in the early 1990s, it is that metal capillary is bent to serpentine configuration, and inside need not any capillary wick.The operation principle of oscillating flow heat pipe: in the snakelike loop capillary pipeline of a sealing, be filled with a certain amount of working media, this medium forms the vapour-liquid slug flow and appears at randomly in the snakelike loop under the effect of the surface tension and the cold and hot end temperature difference, realize the heat transmission by phase transformation (evaporation and condensation) and vapour-liquid vibration.
Oscillating flow heat pipe is a kind of new and effective heat transfer element, has wide practical use in fields such as industrial afterheat recovery and high performance heat exchanger.At present, the manufacturing of domestic oscillating flow heat pipe element is still at the experimental stage, and the development of oscillating flow heat pipe heat exchanger is in initial period.Because the ubiquity solder joint reaches the big welding difficult problem that waits of bonding area more in the heat exchange of heat pipe manufacturing process, therefore causes heat pipe complex manufacturing technology, the performance of heat exchanger to be difficult to be protected, the large scale development of heat exchange of heat pipe is subjected to certain restriction.
Summary of the invention
The purpose of this utility model is exactly in order to solve above-mentioned deficiency, provide a kind of have simple in structure, combined and instant, effective simplified processing process, the oscillating flow heat pipe heat exchanger of advantages such as raising heat exchanger performance.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of oscillating flow heat pipe heat exchanger, it comprises a zone of heat liberation, a cold fluid pass and at least one heat pipe; Wherein cold and hot fluid passage adjacent parallel is placed, middle by dividing plate they are separated, described heat pipe passes dividing plate by the heat pipe fixation kit, and with the dividing plate sealing and fixing, the bringing-up section of heat pipe is in the zone of heat liberation, and the cooling section of heat pipe is in the cold fluid pass; The air communication mistake is arranged in the cold and hot fluid passage.
Described heat pipe fixation kit is installed on the heat exchanger dividing plate removably.
Described heat pipe fixation kit comprises flanged (FLGD) retainer plate and places the inner notched sheet metal of retainer plate.
Described heat pipe has many, wherein per two heat pipes are one group, place a flanged (FLGD) retainer plate, and notched sheet metal is put in the middle of two heat pipes, all heat pipe is arranged by in-line arrangement or fork row mode, and notched sheet metal then is fixed on flanged (FLGD) retainer plate in modes such as welding.
Described oscillating flow heat pipe is to vacuumize the snakelike tubule that working medium is injected in the back.
Described working medium is water, ethanol or acetone and composition thereof.
A kind of oscillating flow heat pipe heat exchanger assembling mode of the present utility model, oscillating flow heat pipe is snakelike tubule, vacuumizes the back and injects working medium.Snakelike tubule adopts metal tubes such as copper pipe, and internal diameter is 0.5～5mm, and working media is water, ethanol, acetone and composition thereof etc. in the pipe, and vacuum is 1 * 10 in the pipe
-1～1 * 10
-3Pa, liquid filled ratio are 40%～70%.
Technology provided by the utility model compared with prior art has the following advantages:
Heat pipe passes dividing plate by the heat pipe fixation kit, and with the dividing plate sealing and fixing, solved in the present heat exchange of heat pipe manufacturing process ubiquitous solder joint effectively and reached the big welding difficult problem that waits of bonding area more.Simple to operate, the low cost of manufacture of heat pipe mounting means of the present utility model, every group of heat pipe independently installed by fixation kit, can avoid producing a large amount of weld bonds, thereby working (machining) efficiency and product quality have been improved, and easy accessibility, maintenance for convenience detach when certain root heat pipe goes wrong, this utility model can play a multiplier role for the making of large-scale heat exchange of heat pipe.
