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

[0047] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0048] like Figure 1-3 A water-cooled plate heat exchanger with a circular structure is shown, including a base plate 10 and a cover plate 20. The base plate 10 and the cover plate 20 are of circular structure, and the cover plate 20 and the base plate 10 are assembled together to form a circular cavity. Cooling fluid (preferably water) flows in the cavity, and baffles 401-403 and cylindrical fins 501-503 are arranged on the substrate 10, the baffles include the first baffle 401 located in the center of the substrate, surrounded by the first The second baffle plate 402 outside the baffle plate 401 and the third baffle plate 403 surrounding the outside of the second baffle plate 402; the first baffle plate, the second baffle plate, and the third baffle plate are circular arcs with the center point of the substrate as the center structure;

Abstract

The invention provides a circular-structure plate heat exchanger for controlling flow by comparing adjacent temperatures. The circular-structure plate heat exchanger comprises a base plate and a coverplate, the base plate and the cover plate are of a circular structure, the cover plate and the base plate are assembled together to form a circular cavity, cooling fluid flows in the cavity, an inletis formed in the center of the cover plate, and a temperature sensor is arranged on the outer wall face of the base plate; the temperature sensor is in data connection with the controller, and the controller automatically controls the fluid flow of the inlet according to the data of the temperature sensor; and the controller extracts the temperature data according to the time sequence, the temperature difference of the temperature data is obtained by comparing the temperature data of the adjacent time periods, and the controller automatically controls the fluid flow of the inlet according tothe temperature difference. According to the circular-structure plate heat exchanger for controlling flow by comparing the adjacent temperatures, the situation that heat exchange and heat dissipationcannot be conducted in time due to too much or too little heat exchange fluid is avoided, and it is avoided that the temperature of a heat source is too high or too low to affect operation of the heatsource.

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 circular structure plate heat exchanger in which a flow guide structure and column ribs are combined. 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 stamped concave-convex stainless steel plates. The concave-convex lines between 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. ...
