Abstract
The utility model relates to a high-efficiency bellow heat exchanger for cooling liquid, which comprises a shell. A heat exchange pipe and partition boards are arranged in a cooling chamber of the shell; the upper side and the lower side of the shell are respectively connected with a liquid inlet pipe mouth and a liquid outlet pipe mouth; and two ends of the heat exchange pipe are respectively connected with a front water chamber and a rear water chamber and communicated with a water inlet pipe mouth and a water outlet pipe mouth. The high-efficiency bellow heat exchanger is characterized in that an arc spiral groove is arranged on the pipe wall of the heat exchange pipe; and partition boards of the cooling chamber are arranged at interval from up down and arranged from left to right in a staggering way. The heat exchange pipe is a stainless steel heat exchange pipe provided with the arc spiral groove. The high-efficiency bellow heat exchanger markedly improves the heat exchange efficiency; as the stainless steel pipe is adopted, the corrosion resistance is greatly enhanced, and the service life can be effectively prolonged; the arc spiral groove ensures that the inside of the pipe is not easy to scale, and the cleaning frequency can be reduced; by adopting the stainless steel pipe, the mechanical property is improved, and the vibration resistance is enhanced; and in addition, the pipe wall is relatively thinned, so materials can be saved, the cost is reduced, the volume and the weight of an oil cooler are reduced, and the structure is more compact.
Description
Technical field
The utility model relates to a kind of efficient ripple screwed pipe heat exchanger that is used for liquid cools.
Background technology
Heat exchanger is mainly used in the cooling to lubricated wet goods liquid.The quality of heat exchanger performance depends on the performance of heat exchanger tube to a great extent.Existing heat exchanger is by formations such as housing, heat exchange (cooling) tube bank, front and back hydroecium, the liquid turnover mouth of pipe, the water turnover mouths of pipe; usually heat exchanger tube is a light pipe; heat exchange property is not high enough; in order to improve exchange performance; existing mode is to adopt the copper pipe of good heat conductivity as heat exchanger tube; this not only makes the cost of product improve greatly, and selects for use copper pipe also to exist this corrosion resistance strong inadequately, and self intensity is low, the problem of easy fouling.In addition, the dividing plate setting in the existing heat exchanger cooling chamber is also unreasonable, and turbulence effect is strong inadequately, also can influence the heat exchanger effectiveness of heat exchanger to a certain extent.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art existence and provides a kind of rate of heat exchange height, the more rational efficient ripple screwed pipe heat exchanger of structure setting.
The utility model for the technical scheme that problem adopted of the above-mentioned proposition of promptly determining is:
Include housing, cooling chamber is installed on heat exchanger tube and disposes dividing plate in the housing, the upper and lower side of housing is connected to the feed liquor mouth of pipe and the fluid mouth of pipe respectively, the two ends of heat exchanger tube join with forward and backward hydroecium respectively and are communicated with the water-in and water-out mouth of pipe, its difference is that the tube wall of heat exchanger tube is provided with the arc helicla flute, and the dividing plate of cooling chamber between the upper and lower every about staggered installing.
Press such scheme, described heat exchanger tube is for being provided with arc helicla flute stainless steel heat exchanger tube, this heat exchanger tube by stainless strip through roll, welding and ripple compacting form.
Press such scheme, the width of described cooling chamber dividing plate is 2/3～3/4 of cooling chamber intracavity diameter or a cross-sectional width.
The beneficial effects of the utility model are: 1, owing to adopted band arc spiral fluted heat exchanger tube, compare with original light pipe, the variation of this structural pipe wall, the inside and outside heat convection thermal resistance of pipe is reduced greatly, recirculated water forms spiral flow and boundary layer separation flow simultaneously in heat exchanger tube, thereby the heat convection of heat exchanger tube is strengthened, and having improved its heat exchange performance greatly, heat exchanger effectiveness significantly improves; 2, the cooling chamber dividing plate about be crisscross arranged and make that liquid effectively forms turbulent flow in the heat exchanger, further strengthened the heat exchange effect; 3, adopt stainless steel tube, its corrosion resistance has bigger enhancing, and can effectively be prolonged service life, and the arc helicla flute is less scaling in the pipe, can reduce wash number; 4, stainless steel tube has not only improved mechanical performance, has strengthened the antivibration ability, and because the relative attenuate of tube wall can be saved material, reduces cost, and reduces the volume and weight of oil cooler, makes its structure more compact.
