Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of liquid cooling radiator structures, and in particular relates to a liquid cooling radiator with a fixed turbulator. Background Art
[0002] Power modules generate a lot of heat when working. Effectively managing this heat is critical to ensuring the long-term reliability and performance of the power module. The direct-flow liquid cooling heat sink achieves efficient heat dissipation of the power module by directly introducing the coolant into the flow channel in close contact with the heat source of the power module.
[0003] The straight-through liquid-cooled radiator has a simple structure. By setting a plurality of straight liquid-cooling channels inside the radiator, the heat on the power module can be quickly removed to achieve high-speed heat dissipation. However, the coolant will form a laminar state when it flows directly and naturally in the liquid-cooling channel, and a large temperature gradient will be generated in the radiator, which reduces the heat dissipation effect. Therefore, in the prior art, turbulators are often set inside the heat dissipation channel, which can optimize the fluid dynamic characteristics, increase the heat exchange area, and reduce the generation of laminar flow and temperature gradient, thereby improving the heat dissipation efficiency to a certain extent. However, in order to facilitate the insertion of the turbulator, the size of the turbulator is generally slightly smaller than the liquid-cooling channel. Therefore, when the coolant passes through, the turbulator will vibrate and rotate in the liquid-cooling channel, which not only leads to a decrease in the turbulent effect, but also the friction between the turbulator and the liquid-cooling channel will produce particle debris, polluting the coolant and even damaging the radiator. Utility Model Content

[0006] Furthermore, the turbulator includes three turbulator sections.
[0007] Furthermore, the angle formed by the axes of adjacent turbulator sections is 3° to 5°.
[0008] Furthermore, the angles formed by the axes of adjacent turbulator sections are of the same size.

[0010] Furthermore, the pitch of the turbulator at one end close to the liquid inlet is greater than the pitch of the turbulator at one end close to the liquid outlet.

[0023] Reference Figure 1 and Figure 2 As shown, this embodiment discloses a liquid-cooled radiator with a fixed turbulator, including a radiator 1, a liquid cooling channel 2 is opened in the radiator 1, the liquid cooling channel 2 includes a liquid inlet and a liquid outlet, and a turbulator 3 is arranged in the liquid cooling channel 2; the turbulator 3 is in the shape of a spiral coil, including a plurality of turbulator 3 sections connected in sequence, and the axes of adjacent turbulator 3 sections form an angle.
[0024] The present embodiment provides a liquid-cooled radiator with a fixed turbulator 3. The turbulator 3 is arranged in the liquid-cooling channel 2 of the radiator 1. The turbulator 3 is in the shape of a spiral coil and includes a plurality of turbulator 3 sections connected in sequence. The axes of adjacent turbulator 3 sections form an angle, so that the turbulator 3 and the inner wall of the liquid-cooling channel 2 are abutted to form a large friction force, so that the turbulator 3 is fixed in the liquid-cooling channel 2, thereby reducing the vibration and rotation of the turbulator 3 in the liquid-cooling channel 2, and avoiding mutual friction, thereby ensuring the heat dissipation effect of the liquid-cooled radiator 1.
[0025] Specifically, the turbulator 3 includes three sections of turbulator 3 , and the angle formed by the axes of adjacent sections of the turbulator 3 is 3° to 5°.
[0026] As a preference of this embodiment, the angles formed by the axes of adjacent turbulator 3 sections are of the same magnitude, both 4°, and the adjacent angles formed by the axes of the turbulator 3 sections are in opposite directions, so that the turbulator 3 has a better fixing effect in all directions.
[0027] As a further improvement of this embodiment, the pitch of the turbulator 3 near the liquid inlet is greater than the pitch near the liquid outlet, so that the turbulence effect of the coolant on the liquid outlet side is better than that on the liquid inlet side, making the temperature distribution of the coolant in the liquid cooling channel 2 more uniform, thereby improving the heat dissipation performance of the radiator 1.
[0028] Specifically, the liquid cooling channel 2 is cylindrical, and a plurality of the liquid cooling channels 2 are provided, and the plurality of the liquid cooling channels 2 are parallel to each other. As a preferred embodiment of this embodiment, five liquid cooling channels 2 are provided. The radiator 1 is a rectangular parallelepiped structure, and the axis of the liquid cooling channel 2 is perpendicular to the two opposite surfaces of the radiator 1, and forms a liquid inlet and a liquid outlet. As a preferred embodiment of this embodiment, the material of the radiator 1 is one of aluminum and copper.
[0029] In this embodiment, the outer diameter of the turbulator 3 is smaller than the inner diameter of the liquid cooling channel 2 .
[0030] In this embodiment, the heat sink 1 is made of aluminum or copper, and the turbulator 3 is made of stainless steel.
[0031] Working principle: The turbulator 3 is placed in the liquid cooling channel 2 of the radiator 1. Due to the bending angle of the turbulator 3, the turbulator 3 will abut against the inner wall of the heat dissipation channel in the heat dissipation channel, generating a large friction force, thereby suppressing the rotation, vibration and axial displacement of the turbulator 3.
[0032] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
