The invention provides a liquid-cooled plate heat exchanger with variable intervals, including a bottom plate and a cover plate, the bottom plate and the cover plate are square structures, the cover plate and the bottom plate are assembled together to form a square cavity, and the cooling liquid flows in the cavity. A baffle and a rib are arranged on the bottom plate, and the baffle includes a first baffle located at the center of the bottom plate, a second baffle surrounded outside the first baffle, and a second baffle surrounded by the second baffle. The third baffle on the outside and the fourth baffle surrounding the outside of the third baffle, a plurality of ribs are arranged inside the first baffle; the ratio of the length of the baffle wall between the first interval and the first baffle > The ratio of the length of the baffle wall of the second compartment to the baffle wall of the second baffle > The ratio of the length of the baffle wall of the third compartment to the baffle wall of the third baffle > The ratio of the baffle wall of the fourth compartment to the baffle wall of the fourth baffle ratio of lengths. Through the change of the ratio of the space to the wall of the baffle plate, the more the space diffuses to the outside, the smaller the space is, which can improve the heat exchange effect and enhance the heat transfer.

The invention provides a water-cooling tube plate type heat exchanger which comprises a base plate and a cover plate. The cover plate and the base plate are assembled together to form a fluid space. Abaffle plate and a cylindrical fin are arranged on the base plate. The baffle plate comprises a first baffle plate located at the center of the base plate, a second baffle plate encircling the outerside of the first baffle plate and a third baffle plate encircling the outer side of the second baffle plate. The heat exchanger comprises a fluid inlet and fluid outlets formed in the cover plate. Acold fluid inlet is formed in the center of a first square, and the two fluid outlets are separately formed in outer positions of parallel lines formed by two fourth baffle plates. The invention aimsto provide a center diffusing type water cooling plate. A refrigerant inlet / outlet mode of a common water cooling plate is changed by the water cooling plate, the flow equalizing property of a refrigerant in the cold plate is improved by additionally arranging the baffle plate, and the heat-dissipating characteristic of the water cooling plate is improved by arranging column ribs.

The invention provides a water-cooling plate type heat exchanger distributing flow according to a wall surface temperature. When a temperature detected by a fourth temperature sensor is higher than atemperature detected by a fifth temperature sensor by a certain value, a controller automatically controls the flow of a first outlet to be decreased and the flow of a second outlet to be increased; and when the temperature detected by the fifth temperature sensor is higher than the temperature detected by the fourth temperature sensor by a certain value, the controller automatically controls theflow of the first outlet to be increased and the flow of the second outlet to be decreased. By detecting the temperatures of the fourth temperature sensor and the fifth temperature sensor, the water-cooling plate type heat exchanger can determine the amount of heat exchange in a left area and a right area, and automatically control the distribution of fluid on both sides according to the amount ofheat exchange on both sides to ensure that the internal fluid is uniform in heat exchange and the surface temperatures of a lower wall surface are uniform.

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.

The invention provides a design method of a water-cooled tube plate type heat exchanger. The heat exchanger comprises a base plate and a cover plate, the cover pate and the base plate are assembled together to form a fluid space, the base plate is provided with baffles and cylindrical fins, the baffles comprise the first baffle located at the center of the base plate, the second baffle surroundingthe first baffle and the third baffle surrounding the second baffle, and a nusselt number and other formulas are designed through parameters. According to the design method, through a large number ofresearches, the structure of the heat exchanger is simulated, the nusselt number and other formulas of the structure are determined for the first time, and the heat dispersion performance and pump power consumption of a water-cooled plate can be estimated by the formulas.
