Another core of the present utility model is to provide a kind of air-conditioning using above-mentioned dry type shell and tube evaporator.
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the accompanying drawings and be embodied as
The utility model is described in further detail for mode.
Refer to the part-structure signal that Fig. 2, Fig. 2 are coolant distributor assembly disclosed in this utility model embodiment
Figure (gas-liquid separator is not shown).
The coolant distributor assembly of dry type shell and tube evaporator disclosed in this utility model embodiment, including tube sheet 4,
Cylinder 8, liquid-distributing plate 5, gas averaging board 6, cover plate 1 and gas-liquid separator, as shown in Figure 2, the annexation tool between each parts
Body is: cylinder 8 is connected with tube sheet 4, and tube sheet 4 is divided into refrigerant inlet district and refrigerant exit district, actually cylinder by cylinder 8
8 is the separation carried out tube sheet 4 by the rib at middle part, and liquid-distributing plate 5 is connected on the inwall of cylinder 8, and sets near tube sheet 4
Putting, gas averaging board 6 is also connected on the inwall of cylinder 8, and constitutes liquid chamber between liquid-distributing plate 5 and gas averaging board 6, on gas averaging board 6 also
Being fixedly connected with the feed tube 7 leading to liquid chamber, cover plate 1 is connected with tube sheet 4, and cover plate 1 constitutes air chamber with gas averaging board 6,
Being provided with the air inlet pipe 2 leading to air chamber on cover plate 1, feed tube 7 exposes after passing cover plate 1, the gas outlet of gas-liquid separator with
Air inlet pipe 2 is connected, and liquid outlet is connected with feed tube 7, and certainly, the entrance of gas-liquid separator should be connected with refrigerant pipeline.
The distribution principle of coolant distributor assembly disclosed in above-described embodiment is as follows:
The liquid refrigerants being flowed into feed tube 7 by the liquid outlet of gas-liquid separator will be directed into, in liquid chamber, utilizing liquid
Momentum liquid refrigerants can be sprawled on liquid-distributing plate 5 as liquid film, meanwhile flowed into the gas of air inlet pipe 2 by gas-liquid separation outlet
State coolant enters in air chamber, and gas, after gas averaging board 6 rectification, is perpendicular to liquid film in the way of impact jet flow and flows into liquid chamber, and
Final carrying of liquids is by entering tube sheet 4 behind the hole on liquid-distributing plate 5.
As can be seen here, in this coolant distributor assembly, defined on liquid-distributing plate 5 owing to liquid refrigerants spreads over uniformly
Liquid film, and the gas after gas averaging board 6 rectification carries the liquid film on liquid-distributing plate 5 and enters in tube sheet 4, compared to existing skill
Art, this kind of coolant distributor assembly achieves gas-liquid two-phase coolant and is here divided evenly in tube sheet 4, given full play to vaporizer
Heat exchange property, under identical heat exchange amount, it is possible to reduce the consumption of heat exchanger tube, and finally reduce dry type shell and tube evaporator
Cost.
Being liquid chamber between gas averaging board 6 and liquid-distributing plate 5, liquid chamber needs the space of suitable size, to ensure to enter in liquid chamber
Liquid the momentum of self can be utilized rapidly to sprawl as uniform liquid film on liquid-distributing plate 5, this utility model embodiment pushes away
Recommending the distance between gas averaging board 6 and liquid-distributing plate 5 is 3mm-10mm, and the distance between gas averaging board 6 and liquid-distributing plate 5 needs can basis
The parameters such as the actual flow velocity of coolant, flow carry out adaptation, such as can be as required by between the two away from being adjusted to 5mm, 8mm
Deng numerical value.
Being air chamber between gas averaging board 6 and cover plate 1, air chamber needs also exist for the space of suitable size, to ensure to enter air chamber
Air-flow the pressure in air chamber can be avoided excessive by gas averaging board rectification simultaneously, in this utility model embodiment recommend gas averaging board 6
And the distance between cover plate 1 is 10mm-100mm, the distance between gas averaging board 6 and cover plate 1 needs the reality according to gaseous coolant
The parameter such as flow velocity, flow carries out adaptation, such as can be as required by between the two away from being adjusted to the numerical value such as 50mm, 70mm.
Understandable, liquid refrigerants has bigger momentum when entering liquid chamber from feed tube 7, and this can be to liquid-distributing plate
5 impact, if liquid-distributing plate 5 and feed tube 7 just to position just offer equal liquid hole, then a large amount of liquid coolants will be directly
By entering tube sheet 4 after equal liquid hole, this does not just have the effect of equal liquid, to this end, disclosed cold in this utility model embodiment
Matchmaker's dispenser assembly, liquid-distributing plate 5 and feed tube 7 just to position be imperforate section, i.e. equal liquid hole is not offered in this position, accordingly,
The position that tube sheet 4 is corresponding with imperforate section is without area under control, does not i.e. lay heat exchanger tube in this position.
Further, in order to can guarantee that the liquid refrigerants being laid on liquid-distributing plate 5 can be fully brought into by gas coolant
In tube sheet 4, hole corresponding on gas averaging board 6, liquid-distributing plate 5 and tube sheet 4 in the present embodiment conllinear on coolant inflow direction is arranged,
The diameter in the hole on gas averaging board 6 and liquid-distributing plate 5 is advisable with 3mm-4mm.
In order to avoid tube sheet 4 being caused greater impact when gas-liquid mixed phase coolant enters tube sheet 4, liquid-distributing plate in the present embodiment
Also it is reserved with the buffer chamber for buffering coolant fluid between 5 and tube sheet 4, and the spacing between liquid-distributing plate 5 and tube sheet 4 is
3mm-10mm, the distance between liquid-distributing plate 5 and tube sheet 4 needs to enter according to parameters such as the actual flow velocity of coolant fluid, flows
Row adaptation, such as can be as required by between the two away from being adjusted to the numerical value such as 5mm, 8mm.
