Description

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

(1) Technical field:

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.

(two) background technology:

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.

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. The force (generated by the medium) will burst and cause the leakage of the medium.

(3) Contents of the invention:

Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to propose a high-efficiency cold and heat exchange film made of an ultra-thin metal plate and shaped like a semicircle with sufficient strength and high heat transfer efficiency.

A semi-circular high-efficiency cooling and heat exchange film made of an ultra-thin metal plate that can solve the above technical problems, the technical solution includes an ultra-thin metal plate, the difference is that the body of the ultra-thin metal plate is uneven, The concave parts are formed between the convex parts, and the convex parts are located on the front or back of the plate body, and the convex parts are in the shape of a hemisphere or a semi-ellipsoid.

According to different usage occasions, the convex parts are evenly distributed or densely distributed on the plate body.

The thickness of the ultra-thin metal plate is 0.05mm-0.3mm.

Beneficial effects of the present invention:

1. The present invention uses an ultra-thin metal plate to make a semicircular high-efficiency cold and heat exchange film, which is not limited by the plane cold and heat exchange area, and can increase the plane cold and heat exchange area several times, ten times for cold and heat exchange , The cold and heat exchange rate can be several times, ten times or even dozens of times higher than that of the planar cold and heat exchange.

2. The present invention has strong cushioning performance, and will automatically disperse the shock wave to each convex part of the plate body to play an automatic protective role. Therefore, it can be made of a thinner metal plate to obtain a higher heat exchange rate. , and there is no need to worry about the problem of brute force.

(5) Specific implementation methods:

The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

The present invention uses an ultra-thin metal plate to make a semicircular high-efficiency cold and heat exchange membrane. The ultra-thin metal plate 1 with a thickness between 0.05mm and 0.3mm is selected and manufactured by stamping or hydraulic forming, so that the ultra-thin metal The board body of the board 1 is uneven, and the concave parts are formed between the convex parts 3. Normally, the convex parts 3 are on the front of the board body, and the shape of the convex parts 3 is hemispherical (or approximately hemispherical). Or semi-ellipsoidal (or approximately semi-ellipsoidal), according to needs, the convex parts 3 are evenly distributed or densely distributed on the plate body, as shown in Figure 1 .

The plate body of the ultra-thin metal plate 1 increases the contact area between the ultra-thin metal plate 1 and the hot and cold medium virtually due to arching numerous convex parts 3, and the contact area increases by several times, tens of The amount increases several times or even dozens of times, so as to obtain a very high cold and heat exchange rate.

The technical solution of the present invention is mostly used in distilled water machines, distilled water pots, wine steamers and novel air conditioners.

Taking the actual application of the above-mentioned distilled water machine, distilled water pot and wine steamer as an example, the cold and heat exchange interface adopts an inverted ultra-thin metal plate 1, so that the hemispherical or semi-ellipsoidal convex parts 3 densely covered on the plate body are downward. , the size of each convex part 3 can be made larger, and a cold water pipe 2 is directly arranged to lead to each convex part 3 so that each convex part 3 is filled with cold water 4; Cold and heat exchange is carried out on the surface of the plate body at part 3, and the condensed water or wine drops 5 are lifted along the arc of the convex part 3 to the lowest point to drop, and a collection vessel is provided below the cold and heat exchange interface to receive water or wine drops , through the above method, you can simply and conveniently collect distilled water or wine, as shown in Figure 2.
