Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 , figure 2 As shown, the heat exchanger of the present invention is composed of a heat exchange tube 5 with fins 14, an upper oil collection chamber 1, a lower oil collection chamber 2, horizontal and oblique ribs 4, 3, and the like. The upper oil collection chamber 1, the heat exchange tube 5 and the lower oil collection chamber 2 are connected with the transformer oil circuit, the heat exchange tube 5 is made of rolled round or oval aluminum or aluminum alloy, and the heat exchange tubes 5 are arranged vertically and parallel , according to design needs can be set to 4 to 20 rows. The upper oil collection chamber 1 and the lower oil collection chamber 2 are parallel to each other, and are horizontally arranged at the upper and lower ends of the multiple rows of vertical heat exchange tubes 5. Above the upper oil co...

Abstract

The invention discloses a tubular radiator for a transformer, comprising an upper oil collecting chamber and a lower oil collecting chamber that are parallel to each another and communicated with an oil circuit of the transformer. The upper oil collecting chamber and the lower oil collecting chamber are communicated with a plurality of rows of heat exchange tubes vertical to the oil collecting chambers. The tubular radiator is characterized in that the heat exchange tubes are rolled round or elliptic aluminium or aluminium alloy heat exchange tubes with fins. A stress automatic adjusting device is arranged between the upper oil collecting chamber and the lower oil collecting chamber on both sides of a plurality of rows of the heat exchange tubes. The invention solves the problems of low heat dissipation, easiness to rust and large weight, and has the advantages of high heat dissipation, good corrosion resistance, difficulty to leak and light weight.

Description

technical field [0001] The invention relates to a tube radiator for a transformer. Background technique [0002] At present, the plate radiator used in the transformer generally adopts the traditional ordinary steel plate material. The use of ordinary steel plate material determines that the fin radiator has low heat dissipation efficiency, easy to rust and heavy weight. Contents of the invention [0003] The purpose of the present invention is to provide a tube radiator for transformers, which can effectively solve the technical problems of low heat dissipation efficiency, easy to rust and heavy weight in the background technology. [0004] To achieve the above object, the present invention is achieved by taking the following technical solutions: [0005] A tubular radiator for transformers, comprising upper and lower upper and lower oil collection chambers connected to the transformer oil circuit in parallel, and the upper and lower oil collection chambers are connecte...
