Description
Technical field
The utility model relates to heat exchanger field, is specially a kind of two-tube gap topping up leakage alarm air cooler.
Background technology
The air cooler full name is an aerial cooler, it be with the various cold fluids in the flowing pipe as cooling medium, the hot-air outer to flowing pipe cools off.Aerial cooler mainly is applied to every field such as petrochemical industry, boats and ships are supporting, power station in the heat exchange field, have advantages such as easy to assembly, good effect of heat exchange, compact conformation and noiseless.After this structure air cooler running time was long, the cooling tube of core group inside was because long-time corrosion has the risk that cooling medium leaks in the generator tube.If air cooler is installed in motor internal and uses, in case taking place, cooling medium leaks, can cause fatal infringement to motor.
For solving the problem that causes cooling medium to leak after corroding appears in air cooler cooling tube long-play, general way is to improve cooling tube material or employing double pipe structure in the industry at present.Wherein adopt the concrete grammar of double pipe structure to be: cooling tube is the double-layer composite pipe that forms by cooling off interior pipe and the cooling mutual expanded joint of outer tube, wherein cool off the outer tube wall circumferential interval and have the guiding gutter that connects the cooling outer tube along the longitudinal direction, the fin expanded joint is on the cooling outer tube, when interior pipe leaks, the water that spills is by the guiding gutter of outer tube wall, flow to the warning device position, warning device is reported to the police, the prompt facility administrative staff, this moment, the air cooler operation had risk, need in time take suitable remedial measure to air cooler.Though this structure has solved the problem that cooling medium leaks, but also there is following shortcoming in actual applications: behind the outer tube wall fluting, contact area in making during the Guan Yuqi expanded joint has reduced, slotted section has formed an air cavity volume, and the heat transfer coefficient of air is very low under this operating mode, causes this structure air cooler heat transfer efficiency more much lower than single tube structure.
Summary of the invention
The utility model causes the low problem of whole air cooler heat transfer efficiency in order to be full of air in the groove that solves existing leakage alarm air cooler outer tube wall, and a kind of two-tube gap topping up leakage alarm air cooler is provided.
The utility model is to adopt following technical scheme to realize: two-tube gap topping up leakage alarm air cooler, comprise by interior pipe and the mutual expanded joint of outer tube and the two-layer compound cooling tube that forms, the outer tube wall circumferential interval has the guiding gutter that connects outer tube along the longitudinal direction, expanded joint has fin on the outer tube, also comprise air side front tube sheet and air side back tube sheet with end, outer tube two ends expanded joint, water side front tube sheet and water rear flank tube sheet with end, interior pipe two ends expanded joint, wherein water side front tube sheet and the water rear flank tube sheet outside is equipped with drive end bearing bracket and rear end cap respectively, innovative point of the present utility model is to leave the anterior diastema that communicates with guiding gutter between air side front tube sheet and the water side front tube sheet, leave the post gap that communicates with guiding gutter between air side back tube sheet and the water rear flank tube sheet, be provided with sealing gasket around anterior diastema and the post gap; The pod apertures that drive end bearing bracket, water side front tube sheet below have mutual perforation and be communicated with anterior diastema, on the drive end bearing bracket and be positioned at the pod apertures place leak pressure sensor alarm is housed, rear end cap, water rear flank tube sheet below have mutual perforation and the aqueous medium that is communicated with post gap is filled mouth.Described leak pressure sensor alarm is existing known products, and its structure and operation principle are well known to those of ordinary skill in the art.
Adopt structural design of the present utility model, after assembling was finished, before using for the first time, the aqueous medium from the rear end cap was filled mouthful water filling in the post gap, will be full of aqueous medium in the guiding gutter between outer tube and the interior pipe afterwards.Because generally the specific heat of air is 1.2KJ/ (KgK), specific heat of water is 4.2KJ/ (KgK), and the heat-transfer effect of water is well more a lot of than air, this air cooler of between inner and outer pipes, filling aqueous medium, and whole heat transfer efficiency can improve about 9% as calculated.If the air cooler of this structure leaks, because the pressure of cooling medium is than the pressure height of water conservancy diversion trough inner water, so can not produce backflow, and the pressure that monitors by the leak pressure sensor alarm that is positioned at the drive end bearing bracket below changes, whether pipe leaks in can detecting very easily, in time takes measures.
Compared with prior art, the utility model is simple in structure, design is ingenious, easy and simple to handle, not only improved the heat transfer efficiency of two-tube air cooler, and efficiently solve the problem that cooling medium leaks, change and fast detecting whether to leak by pressure cooling medium to interior pipe, in time take measures, can ensure that air cooler is applied in to require safe, long service life, not in the occasion of easy-maintaining.
