Description
Technical field
The utility model relates to a kind of air-cooled ducted air conditioner evaporimeter, and particularly a kind of American air-cooled ducted air conditioner evaporimeter belongs to the air conditioner refrigerating technical field.
Background technology
American air-cooled ducted air conditioner adopts copper pipe cover aluminium foil form with evaporimeter more, two evaporimeters is combined into inverted V-shaped arranges, as shown in Figure 1.The evaporimeter of this structure, no matter be two combs, three combs, still four combs all adopt down the stream that outes to arrange that its refrigerant inlet pipe all is arranged on the two ends of inverted V-shaped, refrigerant goes out pipe and is arranged on the other end, only once intersects at the middle part of each evaporimeter.This stream layout of American air-cooled ducted air conditioner evaporimeter, very simple on pipe arrangement, also implement easily.But there are some defectives in it aspect heat transfer, be embodied in: the flow process of each stream of refrigerant is long, and evaporator area can not be fully used, and the heat exchange effect is not very desirable.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, heat exchange efficiency is high, the air-cooled ducted air conditioner evaporimeter of good effect of heat exchange, to overcome weak point of the prior art.
A kind of air-cooled ducted air conditioner evaporimeter by this purpose design, comprise constitute inverted V-shaped about two evaporimeters, its architectural feature is the windward side side that the refrigerant inlet pipe in each stream on the evaporimeter is arranged on evaporimeter, and its refrigerant goes out the outlet air surface side that pipe is arranged on evaporimeter.
Described evaporimeter is divided into different blocks by stream, and block is arranged in order along the length direction of evaporimeter, does not intersect mutually.
Before refrigerant inlet pipe in the described block was arranged on along the width of evaporimeter, refrigerant went out pipe and is arranged at last.Respectively be 3～8 about described block.
Described evaporimeter is made up of two rows and above copper pipe.
The utility model adopts the principle of piecemeal design and suitable distributary design to design the stream of evaporimeter, allows refrigerant all flow through every row of evaporimeter; Simultaneously, the air-flow in conjunction with the evaporimeter cavity distributes the copper pipe quantity of reasonable Arrangement on every row; For improving the refrigeration exchange capability of heat, the flow direction of refrigerant is arranged to along distributary, evaporates while the assurance refrigerant flows in evaporimeter, reduces the heat transfer temperature difference between refrigerant and air to greatest extent, reduces the irreversible loss that different transfer of heat causes, improves the heat exchange effect.
The utility model can maximally utilise the area of evaporimeter by the combination of piecemeal design and suitable distributary design principle, guarantees maximum heat exchange effect.Prove through test of many times, adopt the exchange capability of heat of the American air-cooled ducted air conditioner evaporimeter of this structural design to improve more than 10%.
Description of drawings
Fig. 1 is the stream arrangement schematic diagram of prior art.
Fig. 2 is the stream arrangement schematic diagram of the utility model one embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 2, this air-cooled ducted air conditioner evaporimeter, by about two evaporimeters be merged into inverted V-shape.Each evaporimeter is made up of two rows and above copper pipe, has provided four rows' structure among the figure.Refrigerant inlet pipe in each stream on the evaporimeter is arranged on the windward side side of evaporimeter, and its refrigerant goes out the outlet air surface side that pipe is arranged on evaporimeter.Evaporimeter is divided into different blocks by stream, and block is arranged in order along the length direction of evaporimeter, does not intersect mutually.Before refrigerant inlet pipe in the block was arranged on along the width of evaporimeter, refrigerant went out pipe and is arranged at last.
That is: the air quantity according to the evaporimeter diverse location distributes, and designs different copper pipe trends, to improve the heat exchange effect.Along the flow direction of air, about two heat exchangers respectively be divided into six blocks, each block constitutes a stream, with dashed lines is divided between each stream.According to the piecemeal design principle, the evaporimeter on the left side is divided into by the 7th refrigerant inlet pipe 7
INGo out pipe 7 with the 7th refrigerant
o, the 8th refrigerant inlet pipe 8
INGo out pipe 8 with the 8th refrigerant

o, the 11 refrigerant inlet pipe 11
INGo out pipe 11 with the 11 refrigerant
o, the 12 refrigerant inlet pipe 12
INGo out pipe 12 with the 12 refrigerant
o6 streams forming; The evaporimeter on the right is divided into by the first refrigerant inlet pipe 1
INGo out pipe 1 with first refrigerant
o, the second refrigerant inlet pipe 2

o, the 5th refrigerant inlet pipe 5
INGo out pipe 5 with the 5th refrigerant
o, the 6th refrigerant inlet pipe 6
INGo out pipe 6 with the 6th refrigerant
o6 streams forming.Each stream adopts along the distributary principle and designs, the mode of promptly withing too many people coming in and going out, and the import of each stream is the windward side of evaporimeter, exports to be lee face, i.e. the first refrigerant inlet pipe 1
IN, the second refrigerant inlet pipe 2
IN, the 3rd refrigerant inlet pipe 3
