There is simple in construction, need not capillary wick, advantageously reduce unrestricted (the conventional gravity of cost, heating location and mode of heating
The necessary bottom-heated of heat pipe)；Can arbitrarily bend, applied widely；Caliber is little, lightweight, it is easy to accomplish miniaturization and startup
Wait rapidly outstanding advantages.
Existing heat exchanger many employings fin carries out heat exchange, carries along with heat pipe is combined by the development of hot pipe technique with fin
The heat exchanger of high heat transfer effect the most increasingly receives an acclaim, and this utility model is to be combined with pulsating heat pipe by fin, forms gas
Liquid pulsating heat pipe heat exchanger.
Utility model content

The technical scheme that this utility model is taked by its technical problem of solution is:
A kind of gas-liquid pulsating heat pipe heat exchanger, including casing and the gas-liquid pulsating heat pipe being arranged in described casing, wherein,
Described casing includes upper box and lower box, is provided with dividing plate, described gas-liquid pulsating heat pipe between described upper box and lower box
Through dividing plate, a part is positioned in upper box, and another part is positioned in lower box, and gas-liquid pulsating heat pipe is positioned at the portion in upper box
Divide with fin.
Preferably, bottom described upper box, fixed by connecting bolt between the top of dividing plate, lower box.
Preferably, described gas-liquid pulsating heat pipe is restrained by joining end to end into Guan Bi by some single u-shaped metal tubes.
Preferably, the left and right sides of described upper box is provided with air port, and described lower box is provided with water inlet and outlet.
Preferably, it is provided with fan at the air port of described upper box.
Gas-liquid pulsating heat pipe heat exchanger of the present utility model, organically combines gas-liquid pulsating heat pipe with fin, forms gas-liquid
Pulsating heat pipe heat exchanger.The pipeline section of the pulsating heat pipe being positioned at lower box is evaporator section, is positioned at the finned pulsation of upper box
The pipeline section of heat pipe is condensation segment, and during work, when being full of hot fluid in lower box, the bringing-up section of pulsating heat pipe absorbs heat, pipe
Interior in oscillation form, transfer heat to condensation segment, dispelled the heat by fin, be provided with fan at air port, heat is taken away.
Compared with the existing technology, gas-liquid pulsating heat pipe heat exchanger of the present utility model, when being full of hot fluid in its lower box
Time, the bringing-up section of pulsating heat pipe is absorbed heat, in oscillation form in pipe, transfers heat to condensation segment, dispelled the heat by fin, wind
It is provided with fan at Kou, heat is taken away.The diabatic process of whole heat exchanger is tied due to the pulse characteristic between pulsating heat pipe and fin
Structure and strengthened, thus it is high to have heat recovery efficiency, simple in construction, applied widely waits remarkable advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the new gas-liquid pulsating heat pipe heat exchanger of this practicality.
Fig. 2 is the front view of gas-liquid pulsating heat pipe heat exchanger of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, develop simultaneously enforcement referring to the drawings
Example, further describes this utility model.It should be noted that the following stated is only preferable enforcement of the present utility model
Example, the most therefore limits protection domain of the present utility model.
It should be noted that the implementation not illustrating in accompanying drawing or describing, for ordinary skill people in art
Form known to Yuan.Additionally, the direction term mentioned in following example, such as " on ", D score, "front", "rear", " left ",
" right ", " top ", " end " etc., be only the direction with reference to accompanying drawing.Therefore, the direction term of use is used to illustrate not for limiting
This utility model.
This utility model relates to a kind of gas-liquid pulsating heat pipe heat exchanger, as Fig. 1,2, shown, belong to waste heat recovery, heat transfer,
Mass transfer technical field.Including casing 1, gas-liquid pulsating heat pipe 2.Casing 1 is made up of upper box 3, lower box 4, dividing plate 5, upper box
3, lower box 4, dividing plate 5 is connected by connecting bolt 6, and pulsating heat pipe 2 is through dividing plate 5, through upper box 3 and lower box 4,
Being positioned at upper box 3 part with fin, pulsating heat pipe 2 is by joining end to end into by 80 internal diameters U-shaped metal tube less than 5mm
Guan Bi tube bank, in 4 × 20 interlaced arrangement.Upper box 3 both sides are provided with air port 7, and casing 4 is provided with water inlet 8 and outlet 9.Air port 7
Place can arrange fan further.
Hot fluid enters lower box 4 by the water inlet 8 of box bottom, passes to pulsation heat with heat convection for chief commander's heat
Flowing out through outlet 9 after pipe 2, after pulsating heat pipe 2 absorbs heat, its tube fluid is oscillation form, transfers heat to top box
The condensation segment of body 3, casing 3 both sides are provided with air port 7, and heat is shed by the pulsating heat pipe 2 being positioned at condensation segment by fin.
The enhanced heat exchange measure of waste-heat recovery device at present mainly uses the traditional method such as fin and floor, finned heat exchanger
Major defect be that structure is complicated, processed complex, resistance is big, and the major defect of floor heat exchanger is along rib height direction temperature not
