High-efficiency cold and heat exchange membranes made of ultra-thin metal plates shaped like a semicircle

Abstract

The invention discloses a semicircular high-efficient cold-hot exchange membrane fabricated from an ultrathin metal plate, comprising one ultrathin metal plate with a thickness of 0.05-0.3 mm, wherein the plate body of the ultrathin metal plate is uneven; a concave part is formed between convex parts; the convex parts are uniformly or densely distributed on the front face or back face of the plate body; each convex part is hemispherical or semi-ellipsoidal. According to the semicircular high-efficient cold-hot exchange membrane fabricated from the ultrathin metal plate, the restriction from a plane cold-hot exchange area is prevented, the cold-hot exchange can be performed after the plane cold-hot exchange area is increased by multiple times or more than ten times, and the cold-hot exchange efficiency can be increased by multiple times, more than ten times and even several tens of times in comparison with the plane cold-hot exchange. The semicircular high-efficient cold-hot exchange membrane fabricated from the ultrathin metal plate has the advantages that a strong buffer performance is obtained, so that impact waves are automatically dispersed to all convex parts of the plate body, and an automatic protection effect is achieved, therefore the membrane can be fabricated from a thinner metal plate, a higher cold-hot exchange efficiency is obtained, and the blasting problem is not worried necessarily.

Description

[0001] (1) Technical field: [0002] The invention relates to heat exchange between cold and hot media, in particular to a high-efficiency cold and heat exchange membrane made of ultra-thin metal plates in a semicircular shape. [0003] (two) background technology: [0004] Cold and heat exchange, as the name implies, is the heat transfer between the cold and hot media separated by the conductive diaphragm. Depending on the application, one case is to heat the cold media, and the other case is to cool the hot media. The efficiency of heat transfer depends on the temperature difference between the cold and hot media, the material, thickness and contact area of ​​the conductive diaphragm. [0005] The traditional conductive diaphragm uses a smooth thin metal plate, and the thinner the thickness of the thin metal plate, the better the heat transfer efficiency. For example, an ultra-thin metal plate is used, but the problem is that the ultra-thin metal plate has no pressure cushion...

Problems solved by technology

[0005] The traditional conductive diaphragm uses a smooth thin metal plate, and the thinner the thickness of the thin metal plate, the better the heat transfer efficiency. For example, an ultra-thin metal plate is used, but the problem is that the ultra-thin metal plate has no pressure cushioning performance, and it will suffer a slight impact. The force (generated by the medium) will burst and cause the leakage of the medium
