Problems solved by technology

However, in practical applications, it is found that the intelligence of the heat exchanger is not high, and it is impossible to achieve intelligent control and uniform heat transfer. Therefore, it is necessary to design a plate heat exchanger based on intelligent control.

Embodiment Construction

[0049] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] Such as Figure 1-3 A water-cooled plate heat exchanger shown includes a base plate 10 and a cover plate 20, the cover plate 20 and the base plate 10 are assembled together to form a cavity, and a cooling fluid (preferably water) flows in the cavity, and the base plate 10 is provided with The baffles 401-404 and cylindrical ribs 501, 502, the baffles include a first baffle 401 located at the center of the base plate, a second baffle 402 surrounding the first baffle 401, and a second baffle surrounded by the second baffle The third baffle 403 outside 402;

[0051] As preferred, such as Figure 1-2 As shown, the first baffle plate 401 includes four pieces, and intervals are set between adjacent first baffle plates 401, and there is a vertical relationship between adjacent first baffle plates 401, and the extension lines of the four firs...

Abstract

The invention provides a water-cooled plate heat exchanger with a uniform heat exchange effect. A second valve and a third valve are arranged on pipelines of a first outlet and a second outlet correspondingly, the second valve and the third valve are in data connection with a controller, the controller controls the opening degrees of the second valve and the third valve, and therefore the flow offluid of the two outlets is controlled. By adjusting the flow of the fluid of the outlets, the heat exchange amount participating in the fluid on the two sides is adjusted, it is guaranteed that the temperatures on the two sides are kept uniform, and the situation that as the local temperature is too high, a heat source is not subjected to heat exchange in time is avoided.

Description

technical field [0001] The present invention is a further improvement on the previous application, relates to the technical field of heat exchangers, and in particular relates to an intelligently controlled plate heat exchanger combining a flow guiding structure and a column rib. Background technique [0002] The plate heat exchanger is the heat exchanger with the highest heat exchange efficiency among all kinds of heat exchangers at present. It has the advantages of small space occupation and convenient installation and disassembly. It is composed of concave-convex stainless steel plates formed by stamping. The concave-convex lines between the two adjacent plates are combined at 180 degrees. Therefore, the concave-convex ridges between the two plates of the plate heat exchanger form staggered contact points, and the contact points After being combined by vacuum welding, the high-pressure resistant staggered flow structure of the plate heat exchanger is formed. These stagger...
