Abstract
The utility model relates to a metal heat-exchange special shaped corrugated tube which is used for the automobile industry, the internal-combustion engine industry, the motor industry, the petroleum industry, the chemical engineering industry, the machine industry, the train industry, the ship industry, the medicine industry, etc. The shape of the utility model comprises an oval, a plain edge oblate shape, a peach shape, a trapezoid, a half arc shape, an oblate shape, etc., and special shaped tubes are provided with discontinuous convex-concave corrugation. The utility model has the advantages of scientific and novel design, simple and practical manufacturing process, various corrugated tube shapes, low cost, reliable product performance, high thermal efficiency, thermal resistance reduction, no scale formation, long service life, compact structure and small thermal stress.
Description
The utility model relates to the special-shaped bellows of a kind of metal heat exchange that is applied in the industries such as automobile, oil, chemical industry, machinery, train, boats and ships, medicine on the heat exchanger.
At present, the special-shaped bellows of a kind of metal heat exchange that is applied on the heat exchanger in the industries such as domestic and international automobile, internal combustion engine, motor, oil, chemical industry, machinery, train, boats and ships, medicine does not have desirable solution always.Generally at the special occasions of above-mentioned these industries such as the space is less and adopt finned metal heat exchange shape tube in the heat exchanger that thermic load is bigger, this is because shape tube has heat exchange property preferably, and shape tube takes up space little, tube wall is thin, but along with adopting finned metal heat exchange shape tube can not satisfy the less and heat exchange property requirement of the heat exchanger that thermic load is bigger in space far away in the heat exchanger of these industry special occasions of develop rapidly of domestic and international industry, because finned metal heat exchange shape tube manufacturing cost is higher, the manufacturing process complexity, easy fracture, fin easily comes off, increase thermal resistance, cause heat exchanger failure, cause power consumption big.Therefore, the special-shaped bellows of development metal heat exchange is a scientific research task anxious to be solved both at home and abroad always.
The purpose of this utility model be exactly conceive science novelty, features simple and practical process, multiple bellows form in order to provide a kind of, cost price is cheap, properties of product are reliable, heat transfer efficiency is high, reduce thermal resistance, non-scaling, life-span length, compact conformation, metal heat exchange abnormal shape bellows that thermal stress is little.
The purpose of this utility model is achieved in that the special-shaped bellows of this metal heat exchange comprises ellipse, flat limit oblateness, peach shape, trapezoidal, half arc, oblateness etc., and its shape is that the convex-concave of interruption shape ripple is arranged on these section tubes.Main points of the present utility model are its planform and operation principle.Its operation principle and using method are: utilize the bellows interior fluid to excite turbulent flow under general flow velocity, destroy the boundary layer, thereby improve the coefficient of heat transfer greatly, and the low gas side employing of heat exchanging coefficient adds the method for fin at bellows, thereby makes the heat-exchange method of present the best reach combination inside and outside pipe.Adopt variable-cross-section special shaped bellows, use with the exchange capability of heat of area than light pipe, improve 4 times, more finned straight tube improves 2-5 doubly, and can reach non-scaling, solves the thermal stress effects that the exchange heat pipe that expands with heat and contract with cold produces.
Concrete structure of the present utility model is provided by following enforcement and accompanying drawing thereof.
