Abstract
The utility model relates to a reverse spiral winding tubular cooler and relates to the technical field of convection heat exchange. The reverse spiral winding tubular cooler is characterized in that an oil inlet (1-1) and an oil outlet (1-2) are formed at two ends of a box (1) of the cooler, a water inlet (1-3) and a water outlet (1-4) are formed at two lateral ends of the box (1), a shell (2) is disposed on the outer side of the box (1), multiple layers of reverse spiral winding tube bundles (3) are concentrically disposed inside the box (1), and the spiral winding directions of the odd layers of the reverse spiral winding tube bundles (3) and the even layers of the reverse spiral winding tube bundles (3) are opposite. The reverse spiral winding tubular cooler has the advantages that the fluid flowing state is changed to form intense turbulence effect; the length of the reverse spiral winding tube bundles can reach four to six times of that of the shell, and sufficient heat exchange of cold and hot media inside and outside the heat exchange tube bundles can be achieved; the reverse spiral winding tubular cooler is high in pressure bearing capacity, compact in structure, capable of slowly releasing thermal stress, high in heat exchange coefficient, high in heat transfer efficiency, and quite flexible, adaptable and reliable.
Description
Technical field:
The utility model relates to heat convection technical field, is specifically related to a kind of reverse spiral winding pipe type cooler.
Background technology:
In heat convection field, select energy-saving and cost-reducing type cooler to become the important indicator that project quality inspection is checked and accepted, traditional shell cooler exists that heat exchange efficiency reduced year by year, maintenance capacity are large, condensate water reclaims the problems such as difficulty, capital expenditure and power consumption are large.
Utility model content:
The purpose of this utility model is to provide a kind of reverse spiral winding pipe type cooler, it has changed the flow regime of fluid, form strong turbulence effects, because the tube bank of the reverse spiral winding of its screwed pipe can reach four to six times of shell length, can make cold and hot medium inside and outside heat-exchanging tube bundle, fully carry out exchange heat again, its bearing capacity is high, compact conformation, can slowly-releasing thermal stress, and the coefficient of heat transfer is large, heat transfer efficiency is high, has suitable flexibility, adaptability and reliability.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises casing 1, housing 2, the two ends of casing 1 are provided with oil-in 1-1, oil-out 1-2, the two ends of casing 1 side are respectively arranged with water inlet 1-3, delivery port 1-4, housing 2 is arranged on the outside of casing 1, it also comprises reverse spiral winding tube bank 3, and several layers of reverse spiral winding tube bank 3 are arranged on the inside of casing 1 with one heart.
The odd-level of several layers of described reverse spiral winding tube bank 3 and the spiral winding opposite direction of even level, odd-level is clockwise, even level is counterclockwise, on the contrary odd-level is counterclockwise, even level is clockwise.
Described reverse spiral winding tube bank 3 is common tube or screwed pipe, and when reverse spiral winding tube bank 3 is screwed pipe, its winding direction is contrary with the hand of spiral of screwed pipe.
The utility model has following feature:
One, adopt the reverse spiral winding structure of helix tube: existing longitudinal disturbance when medium flows in the reverse spiral winding tube bank 3 of screwed pipe, rotatablely move again, thoroughly destroyed thermal boundary layer, and fluid continuously changes direction in the process of travelling forward.
Two, the high coefficient of heat transfer: adopt reverse spiral winding structure, changed the flow direction of medium, improved heat exchange area, under specific operation, the coefficient of heat transfer of the reverse spiral winding pipe type cooler of screwed pipe can reach 14000W/m
2.
Three, compact monolithic construction: its volume only has 1/5 left and right of the volume of shell-and-tube heat exchanger, saves space, and volume is little, lightweight, is convenient to install, dismantles and cleans, and has reduced the maintenance cost in once mounting and later stage.
Four, long service life, the extension device replacement cycle, saves cost of equipment.
The utlity model has following beneficial effect: the flow regime that has changed fluid, form strong turbulence effects, again because the tube bank of the reverse spiral winding of its screwed pipe can reach four to six times of shell length, can make cold and hot medium inside and outside heat-exchanging tube bundle, fully carry out exchange heat, its bearing capacity is high, compact conformation, can slowly-releasing thermal stress, and the coefficient of heat transfer is large, heat transfer efficiency is high, has suitable flexibility, adaptability and reliability.
