Abstract

A plate-fin type heat exchanger of a transformer comprises a liquid inlet flow pipe and a liquid outlet flow pipe which are connected through a group of heat exchange sheets, liquid flow channels for transformer oil to pass through are arranged inside the heat exchange sheets and arranged in parallel, and two ends of the liquid flow channels are communicated with the inner portion of the liquid inlet flow pipe and the inner portion of the liquid outlet flow pipe respectively. Air flow channels are parallelly arranged outside the heat exchange sheets, the heat exchange sheets are parallelly arranged between the liquid inlet flow pipe and the liquid outlet flow pipe, and the heat exchange sheets are connected and fixed through reinforcing plates. According to heat exchange requirement and space installation position, the plate-fin type heat exchanger of the transformer increases flow velocity of cold air in the air flow channels, reduces resistance, increases circulation flow quantity of a section, and is convenient to maintain and not easy to accumulate ash and scale. Compared with a general traditional heat exchanger, in a limited temperature area and in the same temperature environment, the plate-fin type heat exchanger is remarkable in heat exchange efficiency, and energy-saving effect is improved remarkably.

At present, a large amount of use plate heat exchangers is arranged also to the heat exchanger of industries such as chemical industry, electric power, petrochemical industry, dynamic power machine, its fluid passage in water as heat transfer medium, through substrate and extraneous air realization heat conduction and heat convection.Advantage is to manufacture and design easyly, and shortcoming is that heat exchange weak effect, equipment volume are big, structure is not compact, take up room big, that material is economized consumption is big, invests also greatly, causes equipment cost and operating cost all than higher.
According to heat transfer theory,, install fin additional in heat exchanger tube tube bank outside usually for strengthening the heat transfer of air side; Make full use of the fin inned coefficient of rectangular fin group, with expansion heat-transfer area augmentation of heat transfer, simultaneously in order to improve the fin utilization ratio; Fully optimize fluid turbulent degree between wing; Can obtain preferable augmentation of heat transfer effect, according to on-the-spot installation site and adopt natural draft or the mechanical draft type of cooling, with the fin channels reasonable Arrangement on substrate surface.
The utility model content
The purpose of the utility model provides a kind of transformer board fin heat exchanger, and existing heat-exchanger rig heat exchange efficiency is low, equipment volume big, structure is not compact to solve, it is big to take up room, material province consumption is big, investment is also big, cause equipment cost and operating cost all than higher defective.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
A kind of transformer board fin heat exchanger comprises into fluid flow tube and goes out fluid flow tube, saidly advances fluid flow tube and goes out fluid flow tube and be connected by one group of heat exchanger fin; The heat exchanger fin set inside has the flow channel for liquids that supplies transformer oil to pass through; Flow channel for liquids is arranged in parallel, the flow channel for liquids two ends respectively with advance fluid flow tube with go out the fluid flow tube internal communication, the heat exchanger fin outer setting has the gas flow that is arranged in parallel; Heat exchanger fin is parallel to into fluid flow tube and goes out between the fluid flow tube, and said heat exchanger fin is connected fixing by stiffener.
Said heat exchanger fin comprises substrate and rectangular fin; Said substrate is welded by two blocks of identical punching press steel plates; Between the punching press steel plate, form said flow channel for liquids, outer surface of substrate is established and is coated with aluminum cladding, and rectangular fin is arranged at the substrate both sides; Said rectangular fin is stamped to form by aluminium sheet, forms the gas flow that is arranged in parallel on it.
In an embodiment of the utility model, said gas flow is parallel with the flow channel for liquids direction.
In an embodiment of the utility model, said gas flow is vertical with the flow channel for liquids direction.
This heat exchanger makes transformer oil flow along gas flow is equidirectional along flow channel for liquids direction and air according to heat exchange requirement and space mounting position, and the flow path of heat transferring medium is parallel; Perhaps transformer oil flows along the gas flow direction along flow channel for liquids direction and air in vertical direction; The flow path distributary of heat transferring medium utilizes " stack effect " with augmentation of heat transfer, strengthens the flow velocity of cold air in the gas flow; Reduce resistance; Increase section circulation flow, be difficult for ash deposit and slag buildup, easy to maintenance; Adopt steel-aluminum composite plate material, not only improved corrosion resistance, avoided using the material of expensive simultaneously; Reduced cost, in the finite temperature zone, identical temperature environment; Finned plate heat exchanger is more obvious than general conventional traditional heat exchanger heat exchange effect, and energy-saving effect significantly improves.
