It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The implementation of the present embodiment is described in detail below with reference to specific drawings.

Example one

As shown in fig. 3, in this embodiment, a condensing assembly 1 is provided to exchange heat with a material to be cooled, which may be liquid or gas. The condensation assembly 1 comprises two mutually fixed heat sink plates 11, the edges of which are sealed and a gap is left between them. Convex turbulent flow structures 12 are arranged on the radiating plate pieces 11, and a gap between the two radiating plate pieces 11 and a cavity of each turbulent flow structure 12 jointly form an inner cavity which is used for containing cooling liquid. Each heat dissipation plate 11 is further provided with an inlet and an outlet which are communicated with the inner cavity, and cooling liquid can enter or leave the inner cavity.

Adopt condensation subassembly 1 in this embodiment, when treating the heat dissipation material and carry out the heat transfer, treat that the heat dissipation material flows through its both sides face and inside coolant liquid and carry out the heat transfer, the heat transfer cooling after treat the heat dissipation material leave condensation subassembly 1, the heat absorption intensifies the back coolant liquid and leaves from the export, new coolant liquid from the entry entering continue with next round treat the heat dissipation material and carry out the heat transfer. The turbulent flow structure 12 can slow down the flow rate of the material to be cooled, increase the contact area, and then improve the cooling efficiency of the unit area, and can reduce the required cooling area on the premise of providing the same cooling effect. Moreover, as shown in fig. 4, when the plurality of condensing assemblies 1 are arranged side by side, the flow disturbing structure 12 of the adjacent condensing assembly 1 can restrict the flow passage 3, thereby further improving the heat dissipation efficiency.

Preferably, on the radiating plate piece 11, the vortex structure 12 evenly distributed makes each part radiating effect even on the one hand, and on the other hand, because two radiating plate pieces 11 of condensation subassembly 1's structure is the same completely, further vortex structure 12 also symmetry, even design for the die sinking complexity is low, manufacturing is more convenient, production quality and efficient.

The heat dissipation plate 11 in this embodiment is rectangular, and two opposite corners of the heat dissipation plate are respectively provided with an opening communicated to the inner cavity to respectively form an inlet 14 and an outlet 13, so that the distance between the two is as far as possible, thereby avoiding a circulation dead angle of the cooling liquid in the inner cavity and ensuring continuous and efficient circulation and heat exchange.

Preferably, in the present embodiment, the two heat dissipation plates 11 are completely symmetrical in structure, and the respective turbulent structures 12 are corresponding in position, and the two heat dissipation plates are combined to form a complete chamber, so as to increase the heat dissipation contact surface. In addition, when a plurality of condensing assemblies 1 are arranged side by side, the positions of the turbulent flow structures 12 of any adjacent condensing assemblies 1 can be ensured to correspond to each other, so that a regular flow channel 3 is formed, and the heat exchange efficiency is optimized.

Preferably, the spoiler structure 12 in this embodiment is a spherical structure, and the two spoiler structures 12 corresponding to each other in position have an approximately spherical cavity 121 after being combined. The spherical structure has the advantages that the heat exchange line effect in any direction is the same, the spherical structure is insensitive to the flowing direction of the material to be heated, and the spherical structure is particularly suitable for heat exchange of hot gas with violent internal thermal motion and large flow direction randomness.

Because the two sides of the condensing assemblies 1 are both provided with the turbulent flow structures 12, after the condensing assemblies are arranged in the shell side by side, the flow channel 3 is limited by the turbulent flow structures 12 between every two adjacent condensing assemblies 1, the heat exchange area is increased, the flow speed of the materials to be exchanged is reduced, the heat dissipation efficiency of a unit area is finally improved, and the condenser 2 can have a smaller size under the same heat dissipation effect.

As shown in fig. 4, on two adjacent condensing assemblies 1, the outer ends of the spoiler structures 12 at corresponding positions are abutted against each other to limit the outflow channel 3, so that the material to be radiated can only flow through the side of the spoiler structure 12, and can avoid flowing through between the end parts of the two spoiler structures 12, resulting in no sufficient contact with the spoiler structure 12.

As shown in fig. 2, the housing includes an upper fixing plate 22, a lower fixing plate 24, and a front baffle 21 and a rear baffle 23 arranged in parallel with each condensing unit 1, and is enclosed to form a structure with two open sides. The front baffle 21, the condensing modules 1 and the rear baffle 23 are mounted at the upper end to the upper fixing plate 22 and at the lower end to the lower fixing plate 24.

The cooling liquid enters the interior of the condenser 2 along the cooling liquid inlet pipe 26, enters each condensation assembly 1 in turn to participate in heat exchange, and then flows out of the condenser 2 from the cooling liquid outlet pipe 25.

An outlet 27 for the condensate to flow out is formed on the upper fixing plate 22, and the condensate is prevented from attaching to the inside of the condenser 2 and affecting the heat exchange efficiency.
