Stair type heat radiator of heat radiating fins

Abstract

A radiation fin stepped type radiator belongs to the technical field of transformer accessories. The radiation fin stepped type radiator comprises an oil inlet tube, an oil return tube and a set of radiation fins which are adapted between the oil inlet tube and the oil return tube and used for leading hot oil led in by the oil inlet tube to the oil return tube after heat dissipation of the hot oil; the oil inlet tube comprises a horizontal tube section and an inclined tube section, the inclined tube section is formed by bending the horizontal tube section, the radiation fins comprise parallel radiation fins arranged in parallel and stepped radiation fins arranged in stepped shape; the parallel radiation fins are adapted between the horizontal tube section and one end of the oil return tube, and the stepped radiation fins are adapted between the inclined tube section and the other end of the oil return tube, wherein, the horizontal tube section is a tube section with an oil inlet, while the inclined tube section is a tube section far from the oil inlet. The radiation fin stepped type radiator has the advantages of embodying the effects of uniform flow distribution and balanced heat dissipation, and the material can be saved by application of the stepped radiation fins.

Description

technical field [0001] The invention belongs to the technical field of transformer accessories, and in particular relates to a stepped radiator with cooling fins. Background technique [0002] The heat dissipation effect of the transformer depends to a large extent on the structure of the heat sink. The structure of the currently used heat sink consists of figure 2 As shown, it includes oil inlet and return pipes 1 and 2 and a set of heat sinks 3 connected between the oil inlet and return pipes 1 and 2. The hot oil drawn from the transformer enters through the oil inlet pipe 1 and flows to a group of heat sinks. 3 in the heat dissipation cavity, and the cooled transformer oil is led out from the oil return pipe 2 and enters the transformer, so that the circulation cooling is carried out. The heat sink of this structure mainly has the following disadvantages: since the oil inlet pipe 1 is in a straight and long strip structure, it is obvious that the amount of oil distribut...

AI Technical Summary

Problems solved by technology

The heat sink of this structure mainly has the following disadvantages: since the oil inlet pipe 1 is in a straight and long strip structure, it is obvious that the amount of oil distributed to each heat sink 3 is not uniform. Near 11, that is, the amount of oil received by the heat sink 3 on the right of the position shown in the figure is large; The effect is inconsistent

In view of this, the following problems are caused: processing a group of heat sinks 3 to the same size without distinction seems unrealistic and blind

But the problem is not only this, but also because the heat sink 13 far away from the oil inlet 11 cannot have the proper heat dissipation effect, which makes it difficult to reduce the temperature rise of the transformer, which will affect the operation of the transformer in the slightest, and burn the transformer in severe cases. , causing trouble to the power supply and distribution network
