Embodiment Construction

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0050]In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indica...

Abstract

The invention is applied to the technical field of shock absorption, and provides a damping shock absorber, a pipeline structure, a metal plate structure and refrigerating and heating equipment. The damping shock absorber comprises N shells, N is equal to or greater than 2, N is a natural number, an inner cavity is arranged in each shell, the inner cavity of at least one shell is filled with damping fluid substances capable of flowing with the motion of the shell, and the N shells can be enclosed into an assembly with a through hole adaptive to passing through of a pipeline. The damping shockabsorber is provided with two or more shells, the inner cavities of the shells are filled with the damping fluid substances, when the pipeline or a metal plate vibrates, vibration energy is transferred to the damping fluid substances through the shells, the damping fluid substances move in the inner cavities and collide and rub, and thus the vibration energy of the pipeline or the metal plate is consumed; meanwhile, the damping shock absorber has mass and can change the natural vibration frequency of the pipeline or the metal plate to avoid resonance. In conclusion, the damping shock absorbercan effectively suppress the vibration of the pipeline or the metal plate, and thus prevents the pipeline from fatigue fracture due to violent vibration.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction, and more specifically relates to a damping vibration absorber, a pipeline structure, a sheet metal structure and refrigeration and heating equipment. Background technique [0002] For equipment with structural parts such as piping and / or sheet metal, such as air conditioners, refrigerators, etc., during operation and transportation, the piping and sheet metal are prone to large vibration and stress, which may cause damage to piping and sheet metal in severe cases. Fatigue failure of gold structures. Commonly used vibration reduction methods mainly include imposing constraints on the structural parts to fix them, or adding counterweights to the structural parts, in order to change the natural vibration frequency and mode shape of the piping or sheet metal structure. However, due to the widespread use of frequency conversion technology, these methods are difficult to reduce the vibrati...
