And enter condenser 100.
Below condenser 100 is illustrated.
It is in the embodiment of the present invention with reference to Fig. 2, Fig. 2, condenser 100 and the structure sectional view of side regenerator 200.
Condenser 100 is shell-and-tube heat exchanger, including shell-and-tube heat exchanger housing 101 and heat exchanger tube 102.At the present embodiment
In, some row's heat exchanger tubes 102 arrange in levels and (illustrate only part heat exchanger tube 102 in figure.It should be understood that have at other
In body embodiment, heat exchanger tube 102 can use other arrangement modes.) heat exchanger tube 102 is fixed on shell-and-tube heat exchanger housing

Chilled water.
In condenser 100, heat exchanger tube 102 is made of plastics, and the pipe thickness of heat exchanger tube 102 is 0.1mm～0.5mm.?
In the present embodiment, the pipe thickness of heat exchanger tube 102 is 0.15mm.Relative to metallic heat exchanging tube, the most very thin thickness is at consubstantiality
Increase the heat exchange area of more than ten times under Ji, compensate for the problem that plastics heat transfer property is not enough so that the heat transfer of heat exchanger tube 102
Performance can reach the requirement of Absorption Refrigerator.Owing to heat exchanger tube 102 is made of plastics, relative to using heat dissipation metal pipe,
The weight of condenser 100 can be greatly lowered, it is achieved thereby that lightweight.Owing to plastics possess excellent corrosion resistance,
Thus also be able to avoid producing on-condensible gas owing to heat exchanger tube 102 is corroded, add the work efficiency of Absorption Refrigerator.
Meanwhile, the heat exchanger tube 102 of plastic production is relative to metallic heat exchanging tube, and its sealing is more prone to.
Inventor finds through research, traditional condenser using metallic heat exchanging tube, due to metal sealing difficulty relatively
Greatly, in order to ensure the sealing property of condenser so that its housing can only use steel plate or foundry goods to make, thus increases further

Performance can reach the requirement of Absorption Refrigerator.Owing to heat exchanger tube 202 is made of plastics, relative to using heat dissipation metal pipe,
The weight of regenerator 200 can be greatly lowered, it is achieved thereby that lightweight.Owing to plastics possess excellent corrosion resistance,
Thus also be able to avoid producing on-condensible gas owing to regenerator 200 is corroded, add the work efficiency of Absorption Refrigerator.
The heat exchanger tube 202 of plastic production is relative to metallic heat exchanging tube, and its sealing is more prone to.
Inventor finds through research, traditional condenser using metallic heat exchanging tube, due to metal sealing difficulty relatively
Greatly, in order to ensure the sealing property of condenser so that its housing can only use steel plate or foundry goods to make, thus increases further
The weight of condenser, and corrosion-resistant are added.
To this end, in the present embodiment, the shell-and-tube heat exchanger housing 201 of regenerator 200 is also adopted by plastics and makes so that pipe
Sealing between shell heat exchanger housing 201 and heat exchanger tube 202 can readily realize, the thickness of shell-and-tube heat exchanger housing 201

Except realizing the lightweight of regenerator 200, inventor also wants to realize the miniaturization of regenerator 200.Miniaturization
Regenerator 200 can make Absorption Refrigerator overall volume less such that it is able to be applicable to family or refrigeration work consumption is wanted by other
Seek the highest commercial situations.But, inventor finds during regenerator 200 miniaturization, along with the reduction of refrigeration work consumption,
The circulating load of required working medium also decreases, and correspondingly occurs that heat exchanger tube 202 outer surface can not be brominated lithium solution abundant
Moisten and the unfavorable phenomenon of " dry spot " occurs.In order to avoid there is dry spot, inventor attempts strengthening the flow of circulating pump, far away
More than the worker quality liquid of the circulating load of actual requirement, constantly the hydrops pond bottom regenerator 200 sprays changing of top
On heat pipe 202.But which increase the flow of circulating pump, add parasitic energy consumption and operating cost.It is contrary in absorption

Vaporizer 300 and absorber 400
It is in the embodiment of the present invention with reference to Fig. 4, Fig. 4, vaporizer 300 and the assembly state diagram of side absorber 400.At figure
In 4, right side is vaporizer 300, and left side is absorber 400, is ramp type liquid islocation plate between vaporizer 300 and absorber 400
502.Ramp type liquid islocation plate 502 is considered as a part for vaporizer 300, it is also possible to regard a part for absorber 400 as.Right side
Vaporizer 300 required for chilled water supplied by the throttle orifice 104 bottom the condenser being disposed there above.The evaporation on right side
The effect of device 300 is to make the chilled water of condenser absorb the heat of the cold water of flowing in vaporizer 300 tube side in a large number and vapour
Change, thus reach to the purpose of cold water cooling refrigeration.Absorber 400 on the left of the coolant steam entrance produced.Needed for absorber 400
The concentrated solution wanted is supplied by the supply hole 207 of the regenerator bottoms being disposed there above.Lithium bromide concentrated solution is entered by absorber 400
Row cooling, makes lithium bromide concentrated solution constantly absorb coolant steam thus becomes lithium bromide weak solution.The lithium bromide weak solution obtained
For looping back regenerator, thus complete kind of refrigeration cycle.Ramp type liquid islocation plate 502 is for retaining the liquid carried secretly in coolant steam

Below vaporizer 300 is illustrated.
It is in the embodiment of the present invention with reference to Fig. 5, Fig. 5, vaporizer 300 and the structure sectional view of side absorber 400.
Vaporizer 300 is shell-and-tube heat exchanger, including shell-and-tube heat exchanger housing 301 and heat exchanger tube 302.At the present embodiment
In, some row's heat exchanger tubes 302 arrange in levels and (illustrate only part heat exchanger tube 302 in figure.It should be understood that have at other
In body embodiment, heat exchanger tube 302 can use other arrangement modes.), heat exchanger tube 302 is fixed on shell-and-tube heat exchanger housing
In 301.Operationally, in heat exchanger tube 302, circulation has cold water, and the chilled water carrying out condenser changes at heat exchanger tube 102 and shell-and-tube
Flow between hot device housing 101.The heat of cold water in chilled water a large amount of absorption heat-exchange pipe 302 and vaporize, obtain coolant steam, from
And reach to the purpose of cold water cooling refrigeration.
In vaporizer 300, heat exchanger tube 302 is made of plastics, and the pipe thickness of heat exchanger tube 302 is 0.1mm～0.5mm.?
In the present embodiment, the pipe thickness of heat exchanger tube 302 is 0.15mm.Relative to metallic heat exchanging tube, the most very thin thickness is at consubstantiality
Increase the heat exchange area of more than ten times under Ji, compensate for the problem that plastics heat transfer property is not enough so that the heat transfer of heat exchanger tube 302
Performance can reach the requirement of Absorption Refrigerator.Owing to heat exchanger tube 302 is made of plastics, relative to using heat dissipation metal pipe,
The weight of vaporizer 300 can be greatly lowered, it is achieved thereby that lightweight.Owing to plastics possess excellent corrosion resistance,
Thus also be able to avoid producing on-condensible gas owing to heat exchanger tube 302 is corroded, add the work efficiency of Absorption Refrigerator.
The heat exchanger tube 302 of plastic production is relative to metallic heat exchanging tube, and its sealing is more prone to.
Limited by the physicochemical properties of pure water, for meeting the various refrigeration applications of human comfort's sexual needs, steamed
The evaporating temperature sending out device 300 is generally arranged at about 5 DEG C, and this just requires shell-and-tube heat exchanger housing 301 full of vaporizer 300
About 872Pa is preferably must be held in pressure.Air-tightness is required the highest by this pressure, and inventor finds through research, traditional
Use the vaporizer of metallic heat exchanging tube, owing to the sealing difficulty of metal is relatively big, in order to ensure the sealing property of vaporizer so that its
Housing can only use steel plate or foundry goods to make, thus further increases the weight of vaporizer, and corrosion-resistant.
To this end, in the present embodiment, the shell-and-tube heat exchanger housing 301 of vaporizer 300 is also adopted by plastics and makes so that pipe
Sealing between shell heat exchanger housing 301 and heat exchanger tube 302 can readily realize, the thickness of shell-and-tube heat exchanger housing 301
Degree can reduce.So, further mitigating the weight of vaporizer 300, the corrosion resistance of vaporizer 300 is also strengthened.
As a kind of embodiment, shell-and-tube heat exchanger housing 301 and heat exchanger tube 302 can use the plastics of identical type to make, pass through
Shooting Technique is one-body molded, thus provides excellent sealing property.
Except realizing the lightweight of vaporizer 300, inventor also wants to realize the miniaturization of vaporizer 300.Miniaturization
Vaporizer 300 can make Absorption Refrigerator overall volume less such that it is able to be applicable to family or refrigeration work consumption is wanted by other
Seek the highest commercial situations.But, inventor finds during condenser 100 miniaturization, due to the specific heat capacity of chilled water
Very big, the flow of the chilled water completing the required evaporation of specified refrigerating capacity is the most fewer, needs to arrange the coolant distributor of complexity
So that chilled water is accurately assigned on each heat exchanger tube 302, chilled water is made fully to infiltrate heat exchanger tube 302 and along heat exchanger tube 302 table
Face forms the moisture film (abbreviation falling liquid film) that thickness uniformly declines.Along with coolant evaporation of water, chilled water constantly reduces, to such an extent as to can not
It is sufficiently humidified so as to heat exchanger tube 302 and causes heat exchanger tube 302 appearance that the phenomenon of " dry spot " occurs.The appearance of dry spot, makes vaporizer 300
The coefficient of heat transfer is substantially reduced.Thus, in order to ensure to be sufficiently humidified so as to, need to configure special refrigerant pump, use far more than reality
The chilled water of evaporation capacity, under refrigerant pump pumps, constantly sprays from the bottom of vaporizer 300 the chilled water not having evaporation
The top of vaporizer 300.The existence of refrigerant pump, on the one hand increases the volume weight of refrigeration machine, makes vaporizer 300 be difficult to small-sized
Change, on the other hand increase operating cost.
To this end, the centre-to-centre spacing that inventor exchanges between external diameter and the adjacent heat exchange tubes 302 of heat pipe 302 is optimized.
The external diameter of heat exchanger tube 302 is set to 3mm～5mm, and the centre-to-centre spacing of the adjacent heat exchanger tube 302 that will be located in same row is set to
4mm～6mm, is set to 5mm～8mm by the centre-to-centre spacing of neighbouring heat exchanger tube 302.In the present embodiment, heat exchanger tube 302
External diameter is 3mm；The centre-to-centre spacing of the adjacent heat exchanger tube 302 being positioned at same row is 4mm；The center of neighbouring heat exchanger tube 302
Away from for 7mm.Use the heat exchanger tube 302 of above-mentioned pipe with small pipe diameter, big density array, unit volume obtains bigger heat-exchange surface
Long-pending, thus on the premise of meeting high heat exchange efficiency, realize less volume.The external diameter of heat exchanger tube 302 only has 3mm, same row's
The adjacent gap between heat exchanger tube 302 is only 1mm, and the least gap can play the capillary useful work of chilled water
With.Under the synergy of chilled water surface tension and gravity, a chilled water part forms accumulation, diffusion moistening at gap location
This row's heat exchanger tube 302, another part is dropped onto on the heat exchanger tube 302 of lower floor by gap.Then, at each of heat exchanger tube 302
Gap location, a chilled water part drops onto lower floor by gap, and another part piles up diffusion this heat exchanger tube 302 of moistening.With this
Analogizing, chilled water flows successively through each layer heat exchanger tube 302.Chilled water flows through a layer heat exchanger tube 302 from throttle orifice 104, all relies on
Action of gravity completes.Under specified cooling condition during steady operation, from the chilled water of throttle orifice 104 supply through most going up row's heat exchanger tube
302, arrive when most descending row's heat exchanger tube 302, be just vaporized completely, refrigerant pump needn't be used.When chilled water flows through gap, at table
Under the dual function of surface tension and gravity, in the existing flowing of gap location, there is again accumulation；Gap can be according to the size of chilled water flow
It is automatically adjusted the chilled water piling height at gap location.When chilled water flow is big, the liquid height that gap location is piled up can flood
Heat exchanger tube 302, the flow simultaneously flowing through gap is the biggest.When chilled water flow is less, the liquid height that gap location is piled up is low, but
Due to the wettability on heat exchanger tube 302 surface, cooling medium liquid knows from experience infiltration heat exchanger tube 302, reduces heat exchanger tube 302 surface and occurs " dry
Speckle " chance, improve heat transfer coefficient.So, it is not necessary to special refrigerant pump and coolant distributor are set, reduce operating cost,
It is also beneficial to the miniaturization of vaporizer 300.
It is in the embodiment of the present invention with reference to Fig. 6, Fig. 6, vaporizer 300 and the structural blast figure of side absorber 400.In phase
Between adjacent two row's heat exchanger tubes 302, spaced set has multiple support bar 303, support bar 303 arranged in a crossed manner with heat exchanger tube 302 and
It is mutually perpendicular to heat exchanger tube 302.Support bar 303 is for supporting two neighbouring row's heat exchanger tubes 302, and bears pipe shell type heat exchange
The structural stress that in device housing 301, fine vacuum is brought.In the present embodiment, support bar 303 is made of plastics, to ensure light weight
Change.As a kind of embodiment, support bar 303 uses otherwise identical plastic to make with heat exchanger tube 302, in order to manufacture.
It should be noted that in other detailed description of the invention, the pipe thickness of heat exchanger tube 302 can at 0.1mm～

Separate.
In absorber 400, heat exchanger tube 402 is made of plastics, and the pipe thickness of heat exchanger tube 402 is 0.1mm～0.5mm.?
In the present embodiment, the pipe thickness of heat exchanger tube 402 is 0.15mm.Relative to metallic heat exchanging tube, the most very thin thickness is at consubstantiality
Increase the heat exchange area of more than ten times under Ji, compensate for the problem that plastics heat transfer property is not enough so that the heat transfer of heat exchanger tube 402
Performance can reach the requirement of Absorption Refrigerator.Owing to heat exchanger tube 402 is made of plastics, relative to using heat dissipation metal pipe,
The weight of absorber 400 can be greatly lowered, it is achieved thereby that lightweight.Owing to plastics possess excellent corrosion resistance,
Thus also be able to avoid producing on-condensible gas owing to absorber 400 is corroded, add the work efficiency of Absorption Refrigerator.
The heat exchanger tube 302 of plastic production is relative to metallic heat exchanging tube, and its sealing is more prone to.
Inventor finds through research, traditional absorber using metallic heat exchanging tube, due to metal sealing difficulty relatively
Greatly, in order to ensure the sealing property of absorber so that its housing can only use steel plate or foundry goods to make, thus increases further
The weight of absorber, and corrosion-resistant are added.

Away from for 7mm.Use the heat exchanger tube 402 of above-mentioned pipe with small pipe diameter, big density array, unit volume obtains bigger heat-exchange surface
Long-pending, thus on the premise of meeting high heat exchange efficiency, realize less volume.Between between the adjacent heat exchanger tube 402 of same row
Gap is only 1mm, in this gap location, the surface tension of lithium-bromide solution and gravity synergy so that lithium-bromide solution is at this
At gap, existing lower drip moves, and also has diffusion and piles up such that it is able to ensureing chilled water submergence heat exchanger tube 402 all the time.Lithium bromide is molten
Liquid carries out immersion with heat exchanger tube 402 and falling film type combines heat exchange.Meanwhile, under the capillary effect of lithium-bromide solution, bromine
Change lithium solution without being full of whole shell-and-tube heat exchanger housing 401, it is thus only necessary to lithium-bromide solution can whole submergence heat exchange all the time
Pipe 402.Therefore, it is possible to according to the size adjustment lithium-bromide solution of lithium-bromide solution flow at the deposition height of gap location, make
Obtaining, lithium-bromide solution flow hour little at cooling load, lithium-bromide solution also can the heat exchanger tube of submergence uniformly 402.So, it is not necessary to
Repeatedly pumping can ensure contacting of lithium-bromide solution and heat exchanger tube 402, has effectively stopped dry spot phenomenon, has reduced parasitic energy
Consume and operating cost so that absorber 400 is able to miniaturization.
