Abstract
The invention discloses a supercooling device for improving supercooling degree through baffling expansion and an air conditioning unit. The invention forms a plurality of flash areas which are gradually enlarged along the flowing direction of the refrigerant through the gaps arranged among each group of baffle plate groups, so that when fluid impacts and passes through the flash areas with the sharply enlarged cross section area, the pressure of the fluid is sharply reduced to cause the refrigerant to be evaporated into gas, thereby achieving the supercooling effect.
Description
Technical field
The present invention relates to field of air conditioning more particularly to a kind of supercooling apparatus and air-conditioning that raising degree of supercooling is expanded by baffling
Unit.
Background technique
Heat exchanger is the important component of commercial unit.Compared to other heat exchangers, shell-and-tube heat exchanger is due to sexual valence
It is most widely used than high.The research that exchanger capacity is continuously improved never is interrupted, and improving condenser degree of supercooling is way therein
One of diameter.The problems such as that there are pressure drops is big for supercooling apparatus at this stage, and manufacture is difficult, moreover, lower degree of supercooling is also supercooling
The bottleneck of structure development.
Summary of the invention
Have the defects that degree of supercooling is low to solve heat exchanger in the prior art, the invention proposes one kind to pass through baffling
Expansion improves the supercooling apparatus and air-conditioner set of degree of supercooling.
The invention proposes a kind of supercooling apparatus, including the box body with refrigerant channel, further include be arranged at intervals on it is described
Multiple groups baffle groups on refrigerant channel, the shwoot that there is every group of baffle groups at least one to be gradually expanded along refrigerant flow direction
Area.
In the present invention, the baffle groups include: at least one piece of both ends be bent to form bending part bending plate and with bending
The spaced inclined plate in portion, the interval section between the bending part and inclined plate form shwoot area.
Preferably, bending plate is equipped at intervals with two pieces, and the interval between two adjacent bending parts of the bending plate, which is formed, to be dodged
Send out area.
Baffle groups are equipped with the mounting hole of multiple installation heat exchanger tubes, and close with the inner wall of the upper side or downside of box body
Envelope connection.
Preferably, two neighboring baffle groups recline respectively two sides of box body or so inner wall setting.
Preferably, the section width d of the shwoot slot of shwoot area inlet is the mm of 20 mm >=d >=2.
Preferably, the section of the angle c of the inclined plate and bending part is 160 ° >=c >=90 °, the angle bisection of the angle c
Line is parallel with the flow direction of fluid.
Preferably, the section of the spacing b of adjacent two pieces of baffle groups is 1 m >=b >=0.1m.
Preferably, the section of the height h of the box body is the m of 0.5 m >=h >=0.15, the height area of the baffle groups h1
Between be 0.8h >=h1 >=0.5h.
The present invention also proposes a kind of air-conditioner set, uses above-mentioned supercooling apparatus.
Compared with prior art, the present invention is formed multiple along refrigerant flowing by the gap being arranged between every group of baffle groups
The shwoot area that direction is gradually expanded, thus when fluid impact passes through its pressure of shwoot area that cross-sectional area sharply becomes larger by fluid
It strongly reduces and causes refrigerant evaporation at gas, to achieve the effect that supercooling, due to being provided with the baffle groups at multiple groups interval
To achieve the effect that multiple stage flash evaporation, fluid-pressure drop is gradually reduced, the degree of supercooling of heat exchanger has been stepped up.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the schematic perspective view of one embodiment of baffle groups of the present invention；
Fig. 3 is the top view of one embodiment of baffle groups of the present invention；
Fig. 4 is the top view of another embodiment of baffle groups of the present invention.
Specific embodiment
As shown in Figure 1, the invention proposes a kind of supercooling apparatus, comprising: the box body 1 of supercooling apparatus, box body is in long strip,
Refrigerant flows into simultaneously from the one or both ends of box body 1 and forms refrigerant channel, the outlet outflow being arranged in the middle part of box body 1, in box body
The baffle groups 2 that multiple groups are located on refrigerant channel are arranged at intervals with, baffle groups 2 are equipped with the installation of multiple installation heat exchanger tubes
Hole, the gap of every group of baffle groups 2 form multiple shwoot areas being gradually expanded along refrigerant flow direction, thus when fluid impact is logical
It crosses fluid to strongly reduce across its pressure of shwoot area that cross-sectional area sharply becomes larger and cause refrigerant evaporation at gas, to reach
The effect of supercooling, the baffle groups due to being provided with multiple groups interval to having achieved the effect that multiple stage flash evaporation, make fluid-pressure drop by
Step reduces, and has stepped up the degree of supercooling of heat exchanger.
In the present invention, two neighboring baffle groups 2 recline respectively two sides of box body or so inner wall setting, make refrigerant etc.
Route after fluid is flowed into from the end of box body 1 becomes a curve, makes full use of the intracorporal area of box.
As shown in Figure 2,4, baffle groups include: bending plate 21 and inclined plate 22, and the both ends of bending plate 21 are bent to form bending
Portion 211, bending part 211 is combined with the inclined plate 22 for being arranged at intervals on 21 both ends of bending plate respectively, between inclined plate 22 and bending part 211
Gap formed shwoot area.And be designed on bending plate 21 and inclined plate 22 for install and across heat exchanger tube mounting hole.Wherein,
On the inner wall for the upper side or downside that bending plate 21 and inclined plate 22 are fixed on box body 1, and it is tightly connected by being fully welded with inner wall.
When installing baffle plate, the inlet shwoot slot face fluid flow direction B in shwoot area makes the angular bisector and fluid of angle c
Flow direction is parallel, guarantees flow board expansion shwoot effect.
As shown in figure 3, in a specific embodiment, bending plate 21 altogether there are two, and two bending plates 21 are adjacent along box
The setting of 1 width direction interval of body, the gap between bending part 211 for keeping two bending plates 21 adjacent also forms one and is gradually expanded
Shwoot area, increase the quantity in shwoot area, shwoot facilitation effect is more preferable.
In specific value of the invention, the section of the spacing b of adjacent two pieces of baffle groups is 1 m >=b >=0.1m, preferably b=
0.4m.The section width d of the inlet shwoot slot in shwoot area is the mm of 20 mm >=d >=2, the mm of preferably d=5.The height h's of box body
Section is the m of 0.5 m >=h >=0.15, and the height section h1 of baffle groups is 0.8h >=h1 >=0.5h, preferably h1=0.6h.Box body
Height h can be calculated and determine according to heat exchange, repeat to consider pressure drop and efficiency.The section of the angle c of inclined plate and bending part is 160 °
The comprehensive shwoot for determining novel baffle of >=c >=90 °, bending angle c and shwoot groove width d promotes ability, and width is smaller, bending
Angle is bigger, and shwoot promotes ability stronger.
The present invention also proposes a kind of air-conditioner set, uses above-mentioned supercooling apparatus.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
