[ detailed description ] embodiments

The utility model will be described in detail below with reference to the drawings, wherein examples of the embodiments are shown in the drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Please refer to fig. 1: a double vortex type heat exchanger is characterized by comprising a base plate 10, a cover 20 and a water inlet and outlet hole formed in the cover, wherein a double vortex pipeline is arranged in the base plate 10 and is respectively a hot water flow passage 12 and a cold water flow passage 13. When the cover 20 is covered on the chassis 10, the double vortex pipelines are closed to form two mutually sealed and separated vortex pipelines, and water cannot permeate into the vortex pipelines. The two vortex pipes correspond to the water outlet and the water inlet on the cover 20, respectively.

in industrial production and design, the heat exchanger can be rectangular, square, circular, trapezoidal or regular polygon, in this embodiment, we choose to make it circular, then the chassis 10 and the cover 20 are circular, and the center of the circle is provided with the starting point of the dual vortex pipe, which forms the hot water flow passage 12 and the cold water flow passage 13, respectively. The more practical use scene of course can also be designed into regular polygon, inside spiral double-vortex pipeline.

Because the cold water flow and the hot water flow are required to be coiled in opposite directions, if the cold water flows anticlockwise, the hot water flows clockwise, and the vicinity of one water inlet is necessarily corresponding to the other water outlet.

As shown in fig. 1, hot water enters the heat exchanger from the first water inlet 21 at the center of the circle, and flows counterclockwise along the spiral hot water flow passage 12 until reaching the first water outlet 23.

The cold water channel 13 enters from the second water inlet 22 at the circumference, and flows clockwise along the spiral cold water channel 13 until reaching the second water outlet 24.

A first water outlet 23 corresponding to the hot water channel 12 is disposed near a second water inlet 22 corresponding to the cold water channel 13, and a first water inlet 21 corresponding to the hot water channel 12 is disposed near a second water outlet 24 corresponding to the cold water channel 13.

The cover 20, the base plate 10 and the dual vortex duct in the base plate 10 are made of plastic materials, which meet the food contact standard.

Or the cover 20, the base pan 10 and the dual vortex tube in the base pan 10 are all made of stainless steel.

Still further, it is made of, inter alia, 304 stainless steel.

The working process of the heat exchanger is as follows:

hot water enters the hot water flow channel 12 from the first inlet 21, cool boiled water after temperature reduction flows out from the first water outlet 23, cold water enters the cold water flow channel 13 from the second inlet 22 and flows out from the second water outlet 24, the flow directions of the cold water and the hot water are opposite, the flow channel is narrow and large in height in the flowing process of the cold/hot water, namely the contact area of the cold/hot water is large, the hot water in the flow channel can be continuously cooled due to the flowing length, and the temperature of the cold water can be resistant to temperature rise due to the length of the flow channel. Therefore, the heat of the hot water is absorbed by the cold water when the temperature of the hot water is reduced, and the preheated water with the absorbed heat and the increased temperature enters the heating pipe again, so that the purposes of heat exchange and preheating are achieved, and the water outlet flow of the cold boiled water is increased. The purposes of energy conservation and high efficiency are achieved.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
