Embodiment Construction

[0015] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] like figure 2 As shown, within the range of the projected surface of the contact surface of the two entities, one of the entities 2 is selected, and a threaded hole of a general specification is set in its operable area without affecting its function, and the other entity 1 is required to be in the The projection area where the threaded hole is located is its own entity, that is, it must not be in a hollow state.

[0017] like image 3 As shown, when disassembly is required, a screw of corresponding specifications is loaded in the threaded hole, and the screwdriver's rotational force is converted into several times of pushing force by using it, so that the adhesive force can be easily overcome and the two parts can be separated.

[0018] What is described above is only a preferred embodiment of the present invention, and the presen...

Abstract

The invention discloses a method for separating parts by a thread hole. In a projection surface range of contact surfaces of two solids, one solid is selected, a thread hole with a general specification is formed in an area of the solid capable of operating without influencing functions, and the other solid is self solid in the projection area of the thread hole; when the disassembly is needed, a screw with a corresponding specification is loaded in the thread hole, and the rotating force of the screw is converted to multiple times of pushing force so as to overcome the binding force to separate the two solids. The method can thoroughly separate the contact planes of the two solids under the effect of binding force in a connecting state to prevent the condition of polluting working planes and tools.

Description

technical field [0001] The invention is a method for lightly separating parts by using threaded holes, and relates to the improvement of the metal structure of power electronic parts. Background technique [0002] In the application field of power electronics, power modules or power components are usually mounted on a heat sink. The usual method is: add thermal conductive silicone grease to the contact surface of the two parts, and then lock them with screws to make the two parts fully contact to ensure the best heat conduction effect. [0003] During the above installation process, the heat-conducting silicone grease fills the space where the contact surface is not tightly sealed, and the screw locking process almost squeezes out the air on their contact surface, and then the joint is almost in a vacuum state. Due to the effect of atmospheric pressure, the larger their contact surface, the greater the atmospheric pressure, the greater the vacuum adsorption force between th...
