The specific embodiment
Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.
The utility model provides a kind of pulsating heat pipe formula heat energy reclaiming equipment.Before describing heat energy reclaiming equipment of the present utility model, introduce earlier the operation principle and the characteristics of pulsating heat pipe below.
Fig. 1 is the fundamental diagram of pulsating heat pipe.Pulsating heat pipe is made by capillary 300 bendings that are filled with liquid, and an end (instant heating absorber portion 110) is arranged in hot operation district 100, and the other end (the instant heating section of disengaging 210) is arranged in low-temperature working district 200.When liquid in the heat absorption section 110 absorbed heat in the hot operation district, partially liq became steam, thereby formed at interval steam joint 310 and liquid section 320 in capillary.
As shown in Figure 1, when pulsating heat pipe at one end or certain section when being heated, because internal pressure in the moment imbalance in different bend pipes interval, makes the inner working medium that fills produce the continuous liquid and the concussion campaign of steam.Concussion moving handle heat is delivered to the other parts of pulsating heat pipe module from fire end or position, and further is delivered to external environment, thereby has reached the effect of conducting heat.
By analysis, find that pulsating heat pipe has following characteristics: (1) Working fluid phase changing and single-phase forced convertion contact heat transfer, heat transfer efficiency height.(2) the heat pipe diameter is little, and relative surface area is big, need not extra fin or heat exchanger when heat radiation or further heat exchange.In most of the cases, only utilize the surface area of pulsating heat pipe just can carry out effective heat exchange.(3) the adopting heat pipes for heat transfer amount is big.Main two reason: i, single heat-transfer capability are 3 times (identical sizes) of general heat pipe; Ii, because pulsating heat pipe is a boundling uses (single do not work), cause higher heat-transfer capability.Be that the experimental result of pulsating heat pipe in a heat transfer case compares shown in Fig. 2.When transmitting identical heat energy, metal bar and general heat pipe only under the less situation of total heat transfer, have superiority (total temperature difference is low).Pulsating heat pipe shows highly stable performance in medium and high thermal energy transfer.Along with the increase of input heat flow, total temperature difference almost remains unchanged.(4) low cost of manufacture.Owing to there is not inner liquid to inhale core structure, skipped complicated sintering process and technology in the industrial processes manufacturing, directly the commercial metals capillary to minor diameter carries out processing and fabricating.(5), there is an optimal operating temperature interval for specific pulsating heat pipe.The pulsating heat pipe that with water is working medium is an example, and spending between 150 degree 110 has best heat-transfer effect.
