Abstract
The utility model relates to a parallel flow evaporator for an air conditioner which comprises a coolant inlet, a coolant outlet, multi-hole flat tubes, fins, blocking covers, baffles and a flow collecting tube. Each coolant flowing unit is composed of the multi-hole flat tubes, the baffles and the blocking covers, wherein, the multi-hole flat tubes are used for manufacturing a parallel flow condenser. Two or more than two coolant flow units are connected by connecting rings. The fins are assembled among the multi-hole flat tubes or on both sides of the multi-hole flat tubes are clamped with protective plates. The utility model has the characteristics of low producing cost, high heat exchanging efficiency and good operational reliability.
Description
The utility model relates to refrigeration plant, especially a kind of idle call parallel-flow evaporator.
The used high-efficiency evaporator of existing air-conditioning is very different on structural design with parallel flow condenser efficiently, therefore can not parallel flow condenser production technology simple with technology, reliable, that versatility is good equips and produces the evaporimeter that matches with it.And to design or purchase special equipment production in addition, and as laminated evaporator, not only need to purchase expensive lamination mould and production line, and the scope of application is narrower, be difficult to large-scale promotion and use.
The purpose of this utility model just provides that a kind of production cost is low, heat exchange efficiency is high, can use the production technology of existing parallel flow condenser and equip the idle call parallel-flow evaporator of producing.
The utility model purpose is realized by following technical scheme:
The idle call parallel-flow evaporator is formed a refrigerant flow unit by the porous flat pipe that is used to make parallel flow condenser, header, dividing plate, blanking cover, two or more refrigerant flow units are tied with draw-barring, put between the porous flat pipe fins set or both sides again, the folder upper guard board promptly forms parallel-flow evaporator.Refrigerant enters header from the refrigerant inlet on the header, under the tissue of dividing plate, header and coupling ring, flowing through porous flat pipe by the flow route that designs freezes, last refrigerant flows out from the refrigerant exit on the header, air then passes the passage of being made up of porous flat pipe and fin and is cooled, and finishes heat transfer process.
Idle call parallel-flow evaporator of the present utility model has the following advantages:
1, because the heat exchanger channels of refrigerant is a porous flat pipe, the floor of passage makes passage that the higher coefficient of heat transfer be arranged;
2, the refrigerant flow unit of dividing plate, draw-barring passage and the varying number by varying number is set at diverse location, the heat exchange of refrigerant and air is formed once, secondary, three times ... cross-exchange etc. different number of times, and can avoid taking place flow dead, the balance thermic load improves heat exchange efficiency;
What 3, the porous flat pipe cross section can be done is very little, by the most optimized parameter the pipe distance and the fin pitch of waves is set, and helps reducing air drag, increases the air side heat exchange area, improves heat exchange efficiency;
4, the import and export of refrigerant can design easily in all directions, and structure and process limitation are very little, both can reduce the space and occupy, and reduce the pressure loss again;
5, the process equipment of available manufacturing parallel flow condenser is made the parallel-flow evaporator of plurality of specifications, and the generalization degree height of process equipment reduces production costs greatly;
6, production technology and parts and parallel flow condenser are basic identical, and operating pressure is lower than condenser, so its reliability of products height.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation;
Fig. 2 is a local diagrammatic sketch among Fig. 1;
Fig. 3 is a partial cutaway diagrammatic sketch in side among Fig. 1.
The idle call parallel-flow evaporator comprises refrigerant inlet 1, refrigerant exit 2, fin 3, porous flat pipe 4, backplate 5, blanking cover 6, dividing plate 7, header 9, refrigerant inlet 1, refrigerant exit 2 is located on the header 9, porous flat pipe 4, blanking cover 6, dividing plate 7, header 9 is formed a refrigerant flow unit, header 9 links to each other with porous flat pipe 4, blanking cover 6 is located at header 9 ends, dividing plate 7 is arranged in the header 9, two become plural refrigerant flow unit by draw-barring 8, header 9 is communicated with, the refrigerant of a refrigerant flow unit can enter another refrigerant flow unit by the draw-barring path 10 in the draw-barring, be assembled between the porous flat pipe 4 fin 3 or both sides again, folder upper guard board 5 promptly forms the idle call parallel-flow evaporator.Refrigerant inlet 1 and refrigerant exit 2 can be arranged on all directions of header 9, the quantity of dividing plate 7, and the position can be set as required.
