Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the terms of orientation and positional relationship indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.

Fig. 1 to 2 are schematic structural views of preferred embodiments of the present application, as shown in the figures, the oil tank of the combined type wind power generation transformer includes an oil tank side wall 1 and a heat sink assembly 2, a fixing strip 11 protruding to the outside is provided on the oil tank side wall 1, an installation groove 12 using the oil tank side wall 1 as one of the groove walls is provided on the fixing strip 11, the lower end of the installation groove 12 is closed, the heat sink assembly 2 includes a heat conduction plate 21 capable of being attached to the oil tank side wall 1, installation strips 22 capable of being inserted into the installation groove 12 are provided on both sides of the heat conduction plate 21, a plurality of heat sinks are provided on one side of the heat conduction plate 21 far away from the oil tank side wall 1, a plurality of elastic pieces 13 are provided on the groove wall of the installation groove 12 far away from the oil tank side wall 1 so that the heat conduction plate 21, the heat conduction effect is improved.

In this embodiment, an arc-shaped limiting groove 23 is formed in one side, facing the oil tank side wall 1, of the upper end of the mounting bar 22, and an elastic protrusion 14 capable of extending into the limiting groove 23 is arranged at a corresponding position of the oil tank side wall 1.
