Embodiment Construction

[0010] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0011] see figure 1 , the surface of the heat dissipation plate 1 is provided with several first-level U-shaped grooves 2, and between the first-level U-shaped grooves 2 are several convex strips 3, and the cross-section of the convex strips 3 perpendicular to the axial direction of the heat dissipation plate 1 is rectangular and inverted U. The convex strips 3 with a rectangular cross section and the convex strips 3 with an inverted U-shaped cross section are arranged alternately; the convex strips 3 with a rectangular cross section are provided with a secondary U-shaped groove 4; the opening of the secondary U-shaped groove 4 is a convex curved surface ;...

Abstract

The invention discloses a concave-convex face radiating plate. Multiple first-level U-shaped grooves are formed in the surface of the radiating plate. Multiple protruding bars are arranged between the first-level U-shaped grooves. The sections, perpendicular to the axial direction of the radiating plate, of the protruding bars are in a rectangular shape and an inverted U shape, and the protruding bars with the rectangular sections and the protruding bars with the inverted-U-shaped sections are arranged alternately. Due to the fact that the U-shaped grooves are arranged, a low-temperature medium is closer to the bottom faces of the grooves, the effective heat exchange area of the radiating plate is enlarged, the installation stability of a radiator can be improved due to the arrangement of the buckling grooves, and the phenomenon that the radiating efficiency is affected due to relative displacement generated by vibration of a high-temperature object is avoided.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a heat dissipation plate with a concave-convex surface. Background technique [0002] A heat sink is a structure that conducts heat from a high-temperature object to fluids such as air, water, and oil through heat conduction and heat radiation. In the prior art, people increase the heat transfer area by changing the arrangement of the grooves, but improving the arrangement of the grooves will increase the process steps, or increase the difficulty of mold manufacturing, increase the production cost, and the effective heat dissipation area does not increase significantly. The effect is not ideal. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a heat dissipation plate with a concave-convex surface, which has a large effective heat dissipation area, good heat dissipation effect and stable installati...
