Detailed description of the invention
The liquid dispensing apparatus of the absorption-type cold-hot water dispenser of below, present invention will be described in detail with reference to the accompanying embodiment.
Fig. 2 is the part stereogram of the liquid dispensing apparatus of the absorption-type cold-hot water dispenser of embodiment of the present invention, and Fig. 3 to Fig. 5 is the figure that represents the arrangement of diversified distribution openings.
With reference to figure 2, the liquid dispensing apparatus 90 of embodiment of the present invention has the open rectangular chute 91 in top.In the bottom surface of chute 91, form multiple distribution openings 93 across interval, described distribution openings 93 is for making liquid flow to the heat-transfer pipe 92 of arranging in bottom.The shape of distribution openings 93 can be the diversified shapes such as circle, polygonal, but circular.
Chute 91 forms by the top chute 911 of the 1st influent and with the bottom chute 912 that the mode of reporting to the leadship after accomplishing a task with top chute 911 is arranged in these top chute 911 bottoms.Thus, flow into the flow direction bottom chute 912 of top chute 911, and spread to heat-transfer pipe 92.In embodiment of the present invention, chute is arranged as 2 grades, but the present invention is not limited thereto, can be in varied mode by its progression increase and decrease.
As the liquid dispensing apparatus 90 of embodiment of the present invention is applied to the evaporimeter of absorption-type cold-hot water dispenser, in chute 91, flow into refrigerant liquid, as be applied to absorber, in chute 91, flow into absorption liquid.The liquid dispensing apparatus 90 of embodiment of the present invention is not only applied to absorption-type cold-hot water dispenser, and can be applied to all occasions of distributing or scattering liquid.
As mentioned above, owing to having multiple distribution openings 93 in the area distribution of regulation in chute 91, the ratio of liquid wets heat-transfer pipe 92 changes along with the position of this distribution openings 93, so the position of distribution openings produces larger impact to the heat transfer performance of heat-transfer pipe 92.Therefore, distribution openings 93 must be formed on when can getting fully heat-transfer pipe 92 wet heat transfer performance is remained to most suitable position.
With reference to figure 3, to Fig. 5, when the zone definitions of reporting to the leadship after accomplishing a task of reporting to the leadship after accomplishing a task between region or chute 91 and heat-transfer pipe 92 between chute 911,912 is target area (S1), distribution openings 93 is positioned at target area (S1).In addition when the average diameter of distribution openings 93 that is positioned at target area (S1) is made as to D, can will be effective coverage (S2) than the zone definitions of the little D/2 in target area (S1).The region (S3) that connects the distribution openings 93 at the gabarit place that is positioned at target area (S1) here, at least accounts for 50% of effective coverage (S2).
Account for 85% when above of all chutes 91 if meet the position of distribution openings 93 as above and the distribution openings 93 of area condition, the liquid scattering from chute 91 can fully contact with heat-transfer pipe 92, can guarantee thus the heat transfer performance of heat-transfer pipe 92.
Then, the chute 91 by liquid dissemination to heat-transfer pipe 92, must only be delivered to below from distribution openings 93 by liquid, and must prevent flowed into overflow.The in the situation that of overflowing liquid from chute 91, can not give design discharge to the heat-transfer pipe 92 or other chutes 91 that are positioned at chute 91 belows, cause thus the reduction of the heat transfer performance of heat-transfer pipe, and the liquid overflowing will by mistake flow into heat-transfer pipe 92 or other chutes 91 and hinders flowing of liquid, causes thus the reduction of the heat transfer performance of heat-transfer pipe.Therefore, chute 91 need have the minimum constructive height that does not make the overflow flowing into.
Applicant is conceived to the height of chute 91 and the number of chute 91, the area of distribution openings 93 and the refrigerating capacity correlate of absorption-type cold-hot water dispenser, with the minimum constructive height of inferring out following chute 91.
The height of supposing above-mentioned chute 91 is H (m), and the gross area of above-mentioned distribution openings 93 is A (m
2), the number of above-mentioned chute 91 is N, when the refrigerating capacity of absorption-type cold-hot water dispenser is RT (usRT), liquid dispensing apparatus 90 will meet following formula 1:
[formula 1]
H>2.8×10
-12×RT
2／(A
2×N
2)
, meet the overflow that the liquid dispensing apparatus 90 of above-mentioned formula 1 will not make flows into and be assigned to below.Above-mentioned formula 1 can be applied to top chute 911 and bottom chute 912 simultaneously.Here, the number of chute 91 (N) means the number of the chute at different levels.For example, as shown in Figure 2, in the situation that chute is 2 grades, because top chute 911 is 2, so N is 2, because bottom chute 912 is 8, so N is 8.
In addition, when from top chute 911 to bottom chute 912 influent, as the liquid splash of wandering bottom chute 912 is to beyond bottom chute 912 time, as explanation before, liquid will by mistake flow into heat-transfer pipe 92 and hinders flowing of liquid, causes thus the reduction of the heat transfer performance of heat-transfer pipe.Therefore, bottom chute 912 need have and prevents that wandered liquid splash is to outside minimum constructive height.
The height of supposing above-mentioned bottom chute 912 is H2 (m), and the area of the distribution openings 93 of above-mentioned bottom chute 912 is A2 (m
2), the refrigerating capacity of absorption-type cold-hot water dispenser is RT (usRT), the area of the distribution openings 93 of top chute 911 is A1 (m
2), when the number of above-mentioned chute 91 is N, liquid dispensing apparatus will meet following formula 2:
[formula 2]
H2>(1+4.8×10
-6×RT／(A1×N))
0.5×1.2×10
-12×RT
2／(A2
2×N
2)
The bottom chute 912 that, meets above-mentioned formula 2 can prevent that wandered liquid splash is to chute outside.Here, the number of chute 91 (N) means the chute number at different levels.
Then, chute 91 during to chute 91 below or heat-transfer pipe 92, must moderately be sent liquid dissemination with desirable flow.The size of the distribution openings 93 of this and chute 91 is relevant, thereby the size of the distribution openings 93 of chute 91 must meet defined terms.
Fig. 6 is the figure that represents the liquid flow based on distribution openings size, and Fig. 7 is the chart that represents the changes in flow rate based on distribution openings size.
As shown in Figure 6, as too small in the diameter of distribution openings 93 (D), because liquid flows out with droplet-like, not only can not flow out continuously, but also because the rise time of drop is poor compared with being difficult to obtain greatly desirable flow (Fig. 6 A); As excessive in the diameter of distribution openings 93 (D), because being full of whole distribution openings 3, liquid can not flow out, in the situation that being formed with multiple distribution openings 93, can not make each distribution openings 93 trickle equably, the liquid spreading in a side distribution openings 93 is thus many, produces the inhomogeneous problem (Fig. 6 B) of liquid distribution amount of each distribution openings 93.Therefore, be necessary to design rightly the diameter of distribution openings 93, scatter liquid (Fig. 6 C) equably and with the flow of regulation thereby make all distribution openings 93.
When the height of supposing chute 91 is H (mm), applicant finds that the diameter (D, mm) of distribution openings 93 meets in the situation of following formula 3, can make each distribution openings 93 equably and send liquid with the flow of regulation:
[formula 3]
0.9<D<0.45×H
As shown in Figure 7, as the diameter of distribution openings 93 (D) is less than 0.9mm, because the urgency of the flow (Q) of liquid subtracts and the heat-transfer pipe 92 of can not getting wet fully, as the diameter of distribution openings 93 (D) is greater than 0.45 × Hmm, the thickness thickening of the liquid film on heat-transfer pipe because flow too increases, thereby the heat transfer performance of reduction heat-transfer pipe.Therefore,, when the height of chute 91 (H) meets above-mentioned formula 3, can keep the peak performance of heat-transfer pipe 92.
So far illustrated about preferred embodiment of the present invention, but the present invention is not limited to this, can in the scope of the detailed explanation of the scope of patent application, invention and accompanying drawing, implements all distortion, this also naturally belongs to scope of the present invention.
