Structure.Illustrate as a example by regenerator 201 and condenser 202 below.Fig. 3 A be in the embodiment of the present invention condenser 202 with
The perspective view of side regenerator 201；Fig. 3 B is condenser 202 and side regenerator 201 in the embodiment of the present invention
Cross-sectional structure schematic diagram.In Fig. 3 A and Fig. 3 B, there are two shell-and-tube heat exchangers 300, shell-and-tube heat exchanger 300 structure in left side
Becoming condenser 202, the shell-and-tube heat exchanger 300 on right side constitutes regenerator 201 with the solution dispenser 321 in figure.
Shell-and-tube heat exchanger 300 includes heat exchanger tube 310 and shell-and-tube heat exchanger housing 322.Some row's heat exchanger tubes 310 are presented
Lower floor's arrangement (illustrate only part heat exchanger tube 310 in figure), heat exchanger tube 310 is fixed in shell-and-tube heat exchanger housing 322.Shell
Formula heat exchanger shell 322 constitutes the tube side of shell-and-tube heat exchanger 300, and heat exchanger tube 310 constitutes the shell side of shell-and-tube heat exchanger 300.

Degree increases the heat exchange area of more than ten times under same volume, compensate for the problem that plastics heat transfer property is not enough so that heat exchanger tube
The heat transfer property of 310 can reach the requirement of Absorption Refrigerator.Owing to heat exchanger tube 310 is made of plastics, relative to using gold
Belonging to radiating tube, the weight of shell-and-tube heat exchanger 300 can be greatly lowered, it is achieved thereby that lightweight.Owing to plastics possess excellent
Good corrosion resistance, thus also be able to avoid producing on-condensible gas owing to heat exchanger tube 310 is corroded, add absorption system
The work efficiency of cold.Meanwhile, the heat exchanger tube 310 of plastic production is relative to metallic heat exchanging tube, and its sealing is more prone to.
Inventor finds through research, and traditional shell-and-tube heat exchanger using metallic heat exchanging tube, due to the sealing of metal
Difficulty is relatively big, in order to ensure the sealing property of shell-and-tube heat exchanger so that its housing can only use steel plate or foundry goods to make,
Thus further increase the weight of shell-and-tube heat exchanger, and corrosion-resistant.
To this end, in the present embodiment, the shell-and-tube heat exchanger housing 322 of shell-and-tube heat exchanger 300 is also adopted by plastics and makes,
Sealing between shell-and-tube heat exchanger housing 322 and heat exchanger tube 310 can readily be realized, shell-and-tube heat exchanger housing
The thickness of 322 can reduce.So, further mitigate the weight of shell-and-tube heat exchanger 300, resisting of shell-and-tube heat exchanger 300
Corrosive nature is also strengthened.As a kind of embodiment, shell-and-tube heat exchanger housing 322 and heat exchanger tube 310 can use identical
The plastics of kind are made, one-body molded by Shooting Technique, thus provide excellent sealing property.
Between adjacent two row's heat exchanger tubes 310, spaced set has multiple support bar 301, support bar 301 and heat exchanger tube
310 is arranged in a crossed manner and be mutually perpendicular to heat exchanger tube 310.Support bar 301 is used for supporting two neighbouring row's heat exchanger tubes 310, and

Become, to ensure lightweight.As a kind of embodiment, support bar 301 uses otherwise identical plastic to make with heat exchanger tube 310, in order to system
Make.
Solution dispenser 321 is cuboid, and inside has cavity, and cavity is for flowing for lithium bromide weak solution.Solution divides
Orchestration 321 is arranged on the top of the shell-and-tube heat exchanger 300 on right side, to be collectively forming regenerator 201.In solution dispenser 321
It is evenly arranged with multiple discharge orifice 340.As a kind of embodiment, discharge orifice 340 is strip hole, at the width of solution dispenser 321
It is in a row that degree side upwardly extends and equidistantly offer three shapes.On the length direction of solution dispenser 321, spaced set is many
Excretion discharge orifice 205.Discharge orifice 205 for being sprayed to the heat exchanger tube 310 of lower section uniformly by the lithium bromide weak solution in cavity.
In the present embodiment, solution dispenser 321 can also be adopted made of plastic, to reach further lightweight.Make
For a kind of embodiment, solution dispenser 321 is and shell-and-tube heat exchanger housing 322 can use the plastics of identical type to make,
To facilitate manufacture, to assemble and seal.
Except realizing the lightweight of shell-and-tube heat exchanger 300, inventor also wants to realize the small-sized of shell-and-tube heat exchanger 300
Change.The shell-and-tube heat exchanger 300 of miniaturization can make Absorption Refrigerator 100 overall volume less such that it is able to is applicable to house
Front yard or other occasions less demanding to refrigeration work consumption.
But, inventor finds during shell-and-tube heat exchanger 300 miniaturization:
When shell-and-tube heat exchanger 300 is as condenser 202, heat exchanger effectiveness is the highest, is difficult to meet makes after miniaturization
With requiring.Inventor finds through research, and the reason that the heat exchange efficiency of condenser 202 is the highest is: when coolant steam enters cold
Form water droplet on heat exchanger tube 310 surface after there is heat exchange heat release liquefaction with heat exchanger tube 310 in condenser 202, and at the work of gravity
Collecting under with and freely drip, condensed water constantly drips to lower section each row heat exchanger tube 310 during lower, at heat exchanger tube 310 table
Face formed decline moisture film, especially at the bottom camber line of heat exchanger tube 310, the thickness of moisture film is the thickest, increase coolant steam with
Heat transmission resistance between heat exchanger tube 310, is unfavorable for contacting of coolant steam and heat exchanger tube 310, thus causes heat exchanger effectiveness not
High.
When shell-and-tube heat exchanger 300 is as regenerator 201 and absorber 203 a part of, along with the fall of refrigeration work consumption
Low, the circulating load of required working medium also decreases, and correspondingly occurs that heat exchanger tube 310 outer surface can not be brominated lithium solution and fill
Divide moistening and the unfavorable phenomenon of " dry spot " occurs.In order to avoid there is dry spot, inventor attempts strengthening the flow of circulating pump, remote
Far more than the worker quality liquid of the circulating load of actual requirement, constantly the hydrops pond bottom regenerator 201 and absorber 203 is sprayed
Pour on the heat exchanger tube 310 at top.But which increase the flow of circulating pump, add parasitic energy consumption and run into
This.It is contrary in Absorption Refrigerator to miniaturization, the trend of family oriented development.
When shell-and-tube heat exchanger 300 is as vaporizer 204, owing to the specific heat capacity of chilled water is very big, complete specified refrigeration
The flow of the chilled water of the required evaporation of amount is the most fewer, needs the coolant distributor arranging complexity so that chilled water is accurately divided
It is fitted on each heat exchanger tube 310, makes chilled water fully infiltrate heat exchanger tube 310 and uniformly decline along heat exchanger tube 310 surface formation thickness
Moisture film (abbreviation falling liquid film).Along with coolant evaporation of water, chilled water constantly reduces, to such an extent as to can not be sufficiently humidified so as to heat exchanger tube 310
And cause heat exchanger tube 310 appearance that the phenomenon of " dry spot " occurs.The appearance of dry spot, makes the coefficient of heat transfer of vaporizer 204 be substantially reduced.
Thus, in order to ensure to be sufficiently humidified so as to, need to configure special refrigerant pump, use the chilled water far more than actual evaporation,
Under refrigerant pump pumping, constantly from the bottom of vaporizer 204, the chilled water not having evaporation is sprayed the top of vaporizer 204.
The existence of refrigerant pump, on the one hand increases the volume weight of refrigeration machine, makes vaporizer 204 be difficult to miniaturization, on the other hand increases fortune
Row cost.
For these reasons, the centre-to-centre spacing that inventor exchanges between external diameter and the adjacent heat exchange tubes 310 of heat pipe 310 is carried out
Optimize.The external diameter of heat exchanger tube 310 is set to 3mm～5mm, will be located in the centre-to-centre spacing of the adjacent heat exchanger tube 310 of same row
It is set to 4mm～6mm, the centre-to-centre spacing of neighbouring heat exchanger tube 310 is set to 5mm～8mm.In the present embodiment, heat exchange
The external diameter of pipe 310 is 3mm；The centre-to-centre spacing of the adjacent heat exchanger tube 310 being positioned at same row is 4mm；Neighbouring heat exchanger tube 310
Centre-to-centre spacing be 7mm.Use the heat exchanger tube 310 of above-mentioned pipe with small pipe diameter, big density array, unit volume obtains bigger heat
Exchange area, thus on the premise of meeting high heat exchange efficiency, realize less volume.
So, when shell-and-tube heat exchanger 300 is as condenser 202, between the adjacent heat exchanger tube 310 of same row between
Gap is only 1mm, and the least gap can play the capillary beneficial effect of chilled water so that heat exchanger tube 310 surface condensation
Chilled water collect and lower at gap location.The chilled water first condensed will not drop onto the surface of lower floor's heat exchanger tube 310 and form water
Film, makes the water film thickness being suspended on heat exchanger tube 310 bottom cambered surface be minimized, thus improves the overall work of condenser 202
Efficiency.So so that condenser 202 is able to miniaturization.
When shell-and-tube heat exchanger 300 is as regenerator 201 and absorber 203 a part of, adjacent the changing of same row
Gap between heat pipe 310 is only 1mm, in this gap location, the surface tension of lithium-bromide solution and gravity synergy so that bromine
Change lithium solution to move at the existing lower drip of this gap location, also have diffusion and pile up such that it is able to ensureing chilled water submergence heat exchange all the time
Pipe 310.Lithium-bromide solution carries out immersion with heat exchanger tube 310 and falling film type combines heat exchange.Meanwhile, open on lithium-bromide solution surface
Under the effect of power, lithium-bromide solution is without being full of whole housing 201, it is thus only necessary to lithium-bromide solution can whole submergence heat exchange all the time
Pipe 310.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 310.So, it is not necessary to
Repeatedly pumping can ensure contacting of lithium-bromide solution and heat exchanger tube 310, has effectively stopped dry spot phenomenon, has reduced parasitic energy
Consume and operating cost so that regenerator 201 and absorber 203 are able to miniaturization.
When shell-and-tube heat exchanger 300 is as vaporizer 204, the external diameter of heat exchanger tube 310 only has 3mm, and same row's is adjacent
Heat exchanger tube 310 between gap be only 1mm, the least gap can play the capillary beneficial effect of chilled water.?
Under the synergy of chilled water surface tension and gravity, a chilled water part forms accumulation, diffusion this row of moistening at gap location
Heat exchanger tube 310, another part is dropped onto on the heat exchanger tube 310 of lower floor by gap.Then, in each gap of heat exchanger tube 310
Place, a chilled water part drops onto lower floor by gap, and another part piles up diffusion this heat exchanger tube 310 of moistening.By that analogy,
Chilled water flows successively through each layer heat exchanger tube 310.Chilled water flows through a layer heat exchanger tube 310, all relies on action of gravity to complete.At volume
When determining steady operation under cooling condition, chilled water, through going up most row's heat exchanger tube 310, arrives when most descending row's heat exchanger tube 310, the completeest
Pervaporation, needn't use refrigerant pump.When chilled water flows through gap, under the dual function of surface tension and gravity, at gap location
Existing flowing, has again accumulation；Gap can be automatically adjusted the chilled water piling height at gap location according to the size of chilled water flow.
When chilled water flow is big, the liquid height that gap location is piled up can flood heat exchanger tube 310, and 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 310 surface, coolant
Liquid can infiltrate heat exchanger tube 310, reduces heat exchanger tube 310 surface and the chance of " dry spot " occurs, improves heat transfer coefficient.So, it is not necessary to
Special refrigerant pump and coolant distributor are set, reduce operating cost, be also beneficial to the miniaturization of vaporizer 204.
