Abstract
The utility model relates to a composite edge sleeve heat-exchanger, which is adapted to the fields of power, energy, chemicals, refrigeration, air-condition and mechanical processing, etc. The utility model comprises four concentric sleeves, which is characterized in that: the outside surfaces of three sleeves are provided with a plurality of longitudinal edges, and each annular channel is divided into a plurality of sectorial channels in corresponding to the edge number. In order to enhance the efficiency of the heat-exchanger, the composite edge sleeve is improved further: the longitudinal edge is divided into a plurality of sections, and sections crosses with each other to disturb air flow. The utility model has the advantages of small difficulty in processing technology and small resistance, which overcomes the defects of current composite sleeve heat-exchanger and achieves reinforced heat exchange, thereby enhancing the efficiency of the heat-exchanger further.
Description
Technical field
The utility model relates to a kind of improvement that can be used for the composite bushing heat exchanger used in the fields such as power, the energy, chemical industry, refrigeration, air-conditioning, machining, belongs to fluid thermal exchange field.
Background technology
Heat exchanger is all widely applied in fields such as power, the energy, chemical industry, refrigeration, air-conditioning, machining.The requirement of heat exchanging device is efficient, lower resistance (low operating cost) and manufacturing cost, but efficiently usually contradicts with lower resistance (low operating cost) and low manufacturing cost.Compactness of the various compact heat exchangers that adopt (the effective heat transfer area in the unit volume) and heat transfer efficiency are higher at present.Flow channel is in tens millimeter magnitudes in the general compact heat exchanger, and processing welding and operation all cause distortion, problems of crack easily, so manufacturing technology requires very high.Particularly use the heat exchanger that is used as regenerator in the increasing miniature gas turbine recent years, higher owing to it is applied under the higher temperature (about 600 ℃) to material and process technology requirement, and require less resistance.At present, a kind of composite bushing heat exchanger is abroad arranged, also be called the tubule heat exchanger, it is tied together by a plurality of primary elements, constitutes at the two ends welded seal again, this element is made up of 4 concentric sleeves, these 4 sleeves form 3 donuts, the fluid of middle annulus Nei Tongre (or cold), two annulus logical cold (or heat) fluid in addition, realize the exchange of cold fluid and hot fluid, as shown in Figure 1.This heat exchanger is some sleeves, and only more than 20 millimeters of maximum outside diameters, and what see from the end is pore one by one.The advantage of this heat exchanger is easy to process, and is reliable, not yielding, cracking, and flow resistance is little, however its heat exchange efficiency is still not ideal enough, waits further raising.
Summary of the invention
The purpose of this utility model is that above-mentioned composite bushing heat exchanger is further improved, and provides a kind of and can strengthen the composite rib double-tube heat exchanger that the higher sleeve pipe of heating heat exchange efficiency is equipped with longitudinal rib.
The technical solution of the utility model is: a kind of composite rib double-tube heat exchanger that constitutes by 4 concentric sleeves, be characterized on the outer surface of interior three sleeves, being equipped with many longitudinal ribs, and be divided into and the corresponding a plurality of sector channels of rib number by each circular ring path.
The utility model has the advantages that the process technology difficulty is little, and resistance is little, and has overcome the weak point of existing composite bushing heat exchanger, realize enhanced heat exchange, make efficiency of heat exchanger that further raising arranged.
Description of drawings
Fig. 1 is existing composite bushing heat exchanger structure schematic diagram;
Fig. 2 is the composite rib double-tube heat exchanger structural representation that is equipped with longitudinal rib;
Fig. 3 is the composite rib double-tube heat exchanger structural representation of longitudinal rib segmentation and arranged crosswise.
The specific embodiment
By shown in Figure 2, the composite rib double-tube heat exchanger, it is characterized in by being that 1,2,3,4 four concentric sleeve is formed from outside to inside according to this, on the outer surface of interior three sleeves 2,3,4, be equipped with many longitudinal ribs 5, be divided into and the corresponding a plurality of sector channels 6 of rib number by each circular ring path.In order further to improve efficiency of heat exchanger, above-mentioned composite rib sleeve pipe is done further to improve, improving one's methods is that longitudinal rib is divided into multistage, arranged crosswise is to form the disturbance to air-flow, by shown in Figure 3 between each section.Thereby enhanced heat exchange further improves heat exchanger efficiency.
Claims (2)
1, a kind of composite rib double-tube heat exchanger, it is by forming for (1), (2), (3), (4) four concentric sleeves according to this from outside to inside, it is characterized in that, on the outer surface of interior three sleeves (2,3,4), be equipped with many longitudinal ribs (5), be divided into and the corresponding a plurality of sector channels of rib number (6) by each circular ring path.
2, composite rib double-tube heat exchanger according to claim 1 is characterized in that described longitudinal rib (5) is by multistage and become arranged crosswise to constitute.
