Technical Field

[0001] The invention relates to a vortex and turbulent fin structure, belonging to the technical field of heat exchangers. Background Art

[0002] With the development of modern society and the accelerated pace of life, various high-energy and efficient tools and vehicles have become the goal pursued by people. This is reflected in the automotive and electrical fields, which is reflected in the improvement of power and performance of various functional components (such as engines, computer CPUs and other core components), which brings about a greater demand for heat generation. Therefore, the corresponding radiator must be more efficient and have better heat exchange efficiency. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a vortex and turbulent fin structure that can overcome the deficiencies of the prior art.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] A vortex and turbulent fin structure comprises a toothed heat dissipation fin. A plurality of coolant overflow slots are evenly distributed in the toothed slots of the toothed heat dissipation fin. A vortex generating structure is arranged beside the coolant overflow slots.

[0006] The aforementioned eddy current generating structure comprises a base plate fixedly connected to the toothed heat dissipating fins, on which a number of vertical small plates corresponding to the coolant overflow slot holes are evenly distributed, and each vertical small plate passes through the corresponding coolant overflow slot hole.

[0007] The aforementioned base plate is a grid plate, the horizontal slats of the grid plate correspond to the overflow slots of the coolant, and the vertical slats correspond to the toothed grooves of the toothed heat dissipation fins.

[0008] The grid plate is placed on the toothed heat dissipation fins and is fixedly connected to the toothed heat dissipation fins by welding.

[0009] The aforementioned vertical small plates are triangular plates, which are evenly distributed on the horizontal slats of the grid plate.

[0010] Compared with the prior art, the present invention discloses a vortex and turbulent fin structure, which improves the existing heat dissipation fins, opens a plurality of coolant overflow slots on the heat dissipation fins, and adds a vortex generating structure next to the coolant overflow slots. Specifically, the vortex generating structure includes a base plate fixedly connected to the toothed heat dissipation fins, and a plurality of vertical small plates corresponding to the coolant overflow slots are evenly distributed on the base plate, and each vertical small plate passes through the corresponding coolant overflow slot. The present invention can form a vortex in the fluid inside the radiator by adding coolant overflow slots on the heat dissipation fins and combining the vortex generating structure, which significantly improves the heat exchange efficiency and solves the problem that the existing single-structure fins such as straight fins and notched fins can only form laminar flow and turbulent flow, resulting in low heat exchange efficiency and high energy consumption.

[0011] The beneficial effects of the present invention are:

[0012] The present invention has a simple structure, low manufacturing cost and convenient assembly. It can form a vortex in the fluid inside the radiator, promote the mixing of cold and hot gases on the fin surface and above the fin, greatly improve the heat exchange efficiency and meet greater heating requirements.

[0013] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0022] like Figure 1-Figure 6 As shown, a vortex and turbulent fin structure includes a toothed heat dissipation fin 1, a plurality of coolant overflow slot holes 2 are evenly distributed in the toothed slots of the toothed heat dissipation fin 1, and a vortex generating structure 3 is provided next to the coolant overflow slot holes 2.

[0023] The vortex generating structure 3 includes a base plate 31 on which a plurality of vertical small plates 32 corresponding to the coolant overflow slot holes 2 are evenly distributed, so that each vertical small plate 32 passes through the corresponding coolant overflow slot hole 2, and the base plate 31 is fixedly connected to the toothed heat dissipating fins 1.

[0024] The base plate 31 is a grid plate, the horizontal slats 312 of the grid plate correspond to the coolant overflow slots 2, the vertical slats 311 correspond to the toothed grooves of the toothed heat dissipation fins 1, and the grid plate is placed on the toothed heat dissipation fins 1 and fixed to the toothed heat dissipation fins 1 by welding.

[0025] The vertical small plates 32 are triangular plates, which are evenly distributed on the transverse strips 312 of the grid plate.

[0026] When the fluid passes through the toothed heat dissipation fins 1, the fluid is affected by its toothed structure and the coolant overflow slots 2, which can destroy the fluid boundary layer and form turbulence; and then affected by the vertical small plates 32, eddies are formed, which effectively improves the heat exchange efficiency between the fluid and the fins, greatly improving the heat exchange capacity of the heat exchanger.
