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 plate heat exchanger capable of intelligently controlling according to the outlet temperature. A second temperature sensor and a third temperature sensor are arranged at fluidoutlets separately, are used for detecting the fluid temperature of two outlets and are in data connection with a controller; the controller automatically controls the fluid flow rate of an inlet according to the fluid temperature of the two outlets; when the detected temperature is higher than the set first temperature, the controller controls the opening degree of a first valve to be increasedto increase the fluid flow rate entering the heat exchanger; and when the detected temperature is lower than the set second temperature, the controller controls the opening degree of the first valve to be reduced to reduce the fluid flow rate entering the heat exchanger. The plate heat exchanger avoids that the heat exchanging fluid is too much or too little to realize timely heat exchange and dissipation and also avoids the temperature of a heat source to be too high or too low to not to affect operation of the heat source.

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...
