Abstract
The invention refers to a kind of compound rib cover heat exchanger for dynamic, energy source, chemistry, cooling, air conditioning and mechanical process fields. It is made up of four concentric cylinders. The character lies in: the outer surface of the inner three cylinders set several discontinuous lengthwise ribs, separates the ring channels into several sector channels with the same quantity to the ribs. In order to upgrades the efficiency of the heat exchanger, the compound rib cylinders are separated into several segments with the lengthwise ribs, the segments are crossly placed in order to form the disturbance to the gas flow. The merits of the invention are that the process difficulty is small, the reinforced heat exchanging is prominent, the resistance increases tightly, thus it overcomes the deficiencies of current compound pipe heat exchanger.
Description
Technical field
The present invention 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, belong to power and energy project technical 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 low manufacturing cost, but efficiently usually contradicts with lower resistance (hanging down 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 pore heat exchanger, it constitutes at the two ends welded seal by a plurality of primary elements also together again, this primary 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.The advantage of this heat exchanger is easy to process, and is reliable, not yielding, cracking, and flow resistance is little, however heat exchange waits further reinforcement.
Summary of the invention
The objective of the invention is above-mentioned composite bushing heat exchanger is further improved, a kind of composite rib double-tube heat exchanger that is equipped with longitudinal rib is provided, this composite rib double-tube heat exchanger can make heat exchange be strengthened.
Technical scheme of the present invention 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 discontinuous longitudinal ribs, and circular ring path has been divided into and the corresponding a plurality of sector channels of rib number.
Advantage of the present invention is that the process technology difficulty is little, and resistance is little, and has overcome the weak point of existing composite bushing heat exchanger, realizes enhanced heat exchange, makes 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, be equipped with many longitudinal ribs 5 on the outer surface of interior three sleeves 2,3,4, circular ring path has been divided into and the corresponding a plurality of sector channels 6 of rib number.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, be equipped with many discontinuous longitudinal ribs (5) on the outer surface of interior three sleeves (2,3,4), circular ring path has been divided into and the corresponding a plurality of sector channels of rib number (6).
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.
