Abstract
The invention discloses a spiral plate forced oil and water cooler for a transformer. The cooler comprises a heat exchange body, wherein the periphery of the heat exchange body is provided with a hot oil inlet, an oil outlet, a cold water inlet and a water outlet respectively; a water passage for circulating cold water and an oil passage for circulating oil are formed in the heat exchange body, have spiral structures and are formed by composite metal plates; the composite metal plate comprises a first metal plate and a second metal plate which are oppositely arranged; and a space formed between the first metal plate and the second metal plate is connected with a leakage alarm. A heat exchange material is the composite metal plate formed by the first metal plate and the second metal plate. The key technical problems of low efficiency, high probability of rusting, low reliability, incapability of alarm for leakage and the like of the conventional spiral plate forced oil and water cooler are solved. The spiral plate forced oil and water cooler has high efficiency, excellent anti-corrosive property, high reliability and leakage alarm function.
Description
Technical field
The present invention relates to a kind of cooler, particularly a kind of transformer spiral-plate forced oil water cooler.
Background technology
The spiral-plate forced oil water cooler that transformer uses at present, generally adopts traditional a kind of general steel plate material.Water and oil lay respectively at the both sides of steel plate, in the time that steel plate is excellent, can there is not Seepage in water and oil, but, on steel plate, there is crack, hole, the side that in water and oil, pressure is larger will be along the crack of steel plate or hole flow to transformer inside, so, the performance of transformer is caused to very big damage.
In view of above technical problem, be necessary to provide in fact a kind of transformer spiral-plate forced oil water cooler that can overcome above-mentioned defect.
Summary of the invention
Object of the present invention provides a kind of transformer spiral-plate forced oil water cooler, once leak or oil leakage phenomenon, can find in time and solve in time, in case leak-stopping water or leakage of oil infiltrate through in transformer.
The technical solution used in the present invention is:
A kind of transformer spiral-plate forced oil water cooler, comprise heat exchanging body, heat exchanging body periphery is respectively arranged with hot oil inlet, oil export, cooling water inlet and delivery port, described heat exchanging body inside is provided with the oily passage of aquaporin that cooling current are logical and fuel feeding circulation, described aquaporin and oily passage are helical structure and are formed by clad metal sheet, this clad metal sheet comprises the first metallic plate and the second metallic plate that are oppositely arranged, and the space forming between this first metallic plate and the second metallic plate is connected with leak alarm; Top and the bottom of described heat exchanging body are respectively arranged with cover plate, and described oil export and cooling water inlet are separately positioned on corresponding cover plate; In described aquaporin and oily passage, be respectively arranged with the spacing column for location, the length of described spacing column is identical with the width dimensions of aquaporin or oily passage respectively.The material of described the first metallic plate and the second metallic plate is identical or different;
Described leak alarm is liquid-level type alarm;
Compared with prior art, cooler of the present invention at least has the following advantages: between cooler water of the present invention and oil, be separated by by clad metal sheet, this clad metal sheet is made up of the first metallic plate being oppositely arranged and the second metallic plate, and the space forming between the first metallic plate and the second metallic plate is connected with leak alarm, so, once when water or oil generation seepage, first flow in alarm and cause and report to the police, thereby technical staff can solve Seepage in time, and then prevent that oil or seepage are in transformer.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail
Refer to shown in Fig. 1 and Fig. 2, transformer of the present invention comprises heat exchanging body 5 with spiral-plate forced oil water cooler, these heat exchanging body 5 inside are provided with two clad metal sheets that are parallel to each other, these two clad metal sheets that are parallel to each other form helical structure, in addition, two clad metal sheets of being parallel to each other form twice and are spaced from each other and coaxial spiral flow channel, and cold fluid and hot fluid flows respectively in two runners, and bending runner provides flowing and heat-transfer effect of optimization for two kinds of fluids.
Please consult especially shown in Fig. 1, the top of described heat exchanging body 5 and bottom are respectively arranged with cover plate 8, are respectively arranged with oil export 2 and cooling water outlet 3 on the cover plate 8 of top and bottom, are respectively arranged with hot oil inlet 1 and delivery port 4 in two sides of heat exchanging body 5.
Described clad metal sheet comprises the first metallic plate 61 and the second metallic plate 63 that are oppositely arranged, this first metallic plate and the second metallic plate are one or both metal materials, can use as required the metallic plate of different-thickness and material compound, refer to shown in Fig. 3, between this first metallic plate and the second metallic plate, form cavity, with leave can be mobile for liquid gap, this gap communicates with leak alarm 7 inside that are arranged on heat exchanging body 5 bottoms by cover plate 8, to give the alarm when the unexpected seepage of any one fluid.In addition, be welded with respectively the spacing column 9 for location in described spiral flow channel, the length of described spacing column 9 equates with the size of corresponding spiral flow channel.
Described leak alarm 7 is liquid-level type alarm, and this leak alarm is the container that fills certain depth liquid, once influent in this container, the water level of liquid in container raises, and reports to the police thereby start alarm.
The present invention adopts double-level-metal plate, and between double-level-metal plate, alarm is installed, therefore, once oil or water generation seepage, it must, through alarm, therefore, also not have can find in time Seepage in inflow transformer at water or the oil of seepage, thereby greatly improve the security performance of cooler, also greatly reduced Seepage having a strong impact on transformer.
