Specifically adopt following manner to realize being tightly connected herein, be provided with seal between the other end of deflector 21 and the other end of heat exchange tube assemblies 100, be specifically such as pasted with sponge.
Be understandable that, also can adopt the sealing that following manner realizes between deflector 21 and heat exchange tube assemblies 100: the other end of deflector 21 and the other end of heat exchange tube assemblies 100 are integral type structure.
See Fig. 4 to Fig. 6, yet another embodiment of the invention provides a kind of roof machine, and it is single cooler type.This roof machine comprises condenser 2 and evaporimeter 7, wherein, and the structure of both condenser 2 and evaporimeter 7 at least one of them heat-exchanger rig adopting embodiment of the present invention to provide.
In the present embodiment, all adopt the structure of above-mentioned heat-exchanger rig for evaporimeter 7 and condenser 2.
See Fig. 4 and Fig. 5, for the condenser 2 in the present embodiment roof machine, it comprises two heat-exchanger rigs, and the quantity of the heat exchange tube assemblies 100 of each heat-exchanger rig is two.Four heat exchange tube assemblies 100 surround the four sides inner concave shape structure for accommodating blower fan 3.Four sides inner concave shape structure central space is for placing blower fan 3.
In prior art, the space that roof machine condenser surrounds is also larger, the technical scheme that above-described embodiment provides, under the prerequisite not changing roof machine shell sizes, this part space is used, increase the heat exchange area of condenser 2, improve ability efficiency, make under the condition of complete machine housing given volume, make full use of its spatial volume.
See Fig. 4 and Fig. 6, for the evaporimeter 7 in the present embodiment roof machine, evaporimeter 7 comprises heat-exchanger rig.The Single port of heat exchange tube assemblies 100 is communicated with dry pipe 18, and the another port of heat exchange tube assemblies 100 is communicated with liquid-dividing head 19.
In the present embodiment, evaporimeter 7 itself adopts a convex structure, and is equipped with deflector 21, and evaporimeter 7 area is increased.And, evaporimeter 7 putting position be convex surface at windward side, object be utilize bending circular arc pipeline produce centrifugal force, make the refrigerant mainly participating in heat exchange be distributed in windward side, windward side wind field is good, and heat exchange is good, and heat exchange dead band can be avoided as much as possible, in wind field good region heat exchange.
The concrete structure of roof machine in the present embodiment is introduced again in detail below in conjunction with Fig. 4 to Fig. 6.
(1) general structure of roof machine
As shown in Figure 1, roof machine is levels structure, and upside is condensation side, and downside is evaporation side.
(2) condensation side
As shown in Figure 4, Figure 5, condensation side forms primarily of grid 1, condenser 2, blower fan 3, guard 4, motor 12 and baffle liner 13.Four angles of grid 1 are provided with angle post 17.Wherein, condenser 2 is four pieces of curved surface condensers by the assembled concave inward structure of bend pipe 14, and the heat exchanger tube in heat exchange tube assemblies 100, is specially copper pipe and can be level trend, also can be vertical trend.Four pieces of condensers 2 are assembled into two module condensate devices, certainly, also can be assembled into the large condenser of single module.Shown in Fig. 5 is the situation of composition two modules.Each module is equipped with sub-steam pipe 15 and liquid-dividing head 16 (also directly can use liquid trap).The air inlet/outlet mode that condensation side adopts side to return out.
Roof machine condenser 2 adopts four pieces of curved surface condenser 2 convex surfaces to be assembled into a concave inward structure to the mode of convex surface by bend pipe 14, when making condensation side space plane size certain, is increased condenser 2 area further.
When refrigerant flows in the bending arc shape pipeline of condenser 2, the state of the vehicle repair major skewness caused by centrifugal force coordinates roof machine condensation side side to return the air inlet/outlet mode, make condenser 2 gaseous coolant mainly participating in heat exchange in wind field good region heat exchange, thus reduce the harmful effect in roof machine heat exchanger heat exchange dead band.
(3) evaporation side
As shown in Fig. 4, Fig. 6, evaporation side primarily of: evaporimeter 7, return air inlet 6, air outlet 9, lower house 10, inner blower parts 22, deflector 21 and compressor (comprising the parts such as electrical appliance kit) 20 and evaporation side pipeline composition.Evaporimeter 7 is a monoblock type curved surface evaporimeter, and its convex surface is facing to return side, and concave surface is facing to air side.The air blow and return of evaporation side can adopt side to go back to side and send to return down with side and send, and send in the present embodiment to adopt side to go back to side.Evaporimeter 7 is equipped with the conventional conduit components and parts such as discharge 18 and liquid-dividing head 19; Return air inlet 6 is a long straight rectangular configuration, and it is highly more than or equal to evaporimeter 7 height, and its area is greater than air outlet 9.Air is transported to air side from return side and is transported to indoor from air outlet 9 by inner blower parts 22.Deflector 21 is positioned at return side, it is a Curved arc structure, mainly contains two effects: one is match with curved surface arcuation evaporimeter 7, and composition is applicable to the air channel of air flowing, the air of return side is guided to the bottom of evaporimeter 7 always, reduce local losses during air flowing; Two is that the system components and parts such as compressor 20 and electrical appliance kit parts and evaporimeter 7 are completely cut off, and provides its installing space.
The evaporimeter 7 of roof machine adopts an overall Curved arc structure, is equipped with curved surface arcuation deflector 21 and forms return air duct, when making space size certain, increased evaporator area further.
When refrigerant flows in the bending arc shape pipeline of condenser 2, the air inlet/outlet mode that the state of the vehicle repair major skewness caused by centrifugal force coordinates roof machine evaporation side side to go back to side to go out, make evaporimeter 7 liquid refrigerants mainly participating in heat exchange in wind field good region heat exchange, thus reduce the harmful effect in roof machine heat exchanger heat exchange dead band.
The centrifugal force size that gaseous coolant and liquid refrigerants produce due to the difference of unit mass in identical curved pipe is also different.Centrifugal force can make the distribution of vehicle repair major refrigerant in pipeline change, and liquid refrigerants can be tending towards near convex side, and gaseous coolant is tending towards near concave side.
(4) miscellaneous part
A, as shown in Figure 4, dividing plate 11 is positioned at complete machine mid portion, and its effect is separated with condensation side at the evaporation side of complete machine; Above compressor part, have a pipe hole 5 in the corner of dividing plate 11, it is the passage that upper and lower sides pipeline connects, and refrigerant is circulated at upper and lower sides.
B, as shown in Figure 4, base plate 8 is positioned at complete machine lowermost end, for supporting complete machine and holding an evaporation side parts such as system part and drip tray.
The roof machine that technique scheme provides, due to the increase of two device heat exchange areas and the raising of heat exchange efficiency, makes the complete machine efficiency under equal conditions be improved.Further, the basis of improving efficiency need not make the amplitude of the increase of complete machine housing or increase less, making complete machine fill cabinet amount can not reduce, and saves cost of transportation.In addition, the housing of roof machine is little, and efficiency is high, and ability is high, and price also has superiority, and is conducive to product and will occupies vantage point in market competition.
