Description

Technical Field

[0001] The utility model belongs to the technical field of liquid cooling radiator structures, and in particular relates to a turbulent heat-averaging liquid cooling radiator. 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 structure of the straight-through liquid cooling radiator is simple. 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, thereby greatly improving the heat dissipation efficiency. However, the turbulence effect formed by the traditional turbulator in the liquid cooling channel is consistent, and the power devices on the radiator are basically heated. The temperature of the coolant is the lowest at the water inlet. Due to the heat accumulation, the closer to the water outlet, the higher the coolant temperature, which leads to a low temperature of the power device near the water inlet, and a high temperature of the power device near the water outlet. The temperature accumulation causes the surface temperature of the radiator near the liquid outlet to be higher than the surface of the liquid inlet, resulting in an uneven distribution of the overall temperature of the radiator, which in turn leads to uneven temperature of the power device, affecting the operating characteristics of the power device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that a large temperature difference exists at both ends of the liquid cooling channel of a straight-through liquid cooling radiator combined with a turbulator, which affects the heat dissipation performance, thereby providing a turbulent heat-averaging liquid cooling radiator.

[0005] A turbulent heat-averaging liquid-cooled radiator comprises a radiator, a liquid cooling channel is provided in the radiator, the liquid cooling channel comprises a liquid inlet and a liquid outlet, a turbulator is arranged in the liquid cooling channel; the turbulator is in the shape of a spiral coil, the axis of the turbulator is a straight line, and the pitch of the turbulator near the liquid inlet end is greater than the pitch near the liquid outlet end.

[0006] Furthermore, the liquid cooling channel is cylindrical.

[0007] Furthermore, a plurality of the liquid cooling channels are provided, and the plurality of the liquid cooling channels are parallel to each other.

[0008] Furthermore, five liquid cooling channels are provided.

[0009] Furthermore, the outer diameter of the turbulator is smaller than the inner diameter of the liquid cooling channel.

[0010] Furthermore, the radiator is a rectangular parallelepiped structure, and the axis of the liquid cooling channel is perpendicular to two opposite surfaces of the radiator, and forms a liquid inlet and a liquid outlet.

[0011] Furthermore, the heat sink is made of one of aluminum and copper.

[0012] Beneficial effect: The utility model discloses a turbulent heat-averaging liquid-cooled radiator, in which a spiral coil-shaped turbulator is arranged in a liquid-cooling channel, and the pitch of the turbulator at the end close to the liquid inlet is larger than the pitch at the end close to the liquid outlet, thereby forming a weaker turbulence effect at the end close to the liquid inlet and a stronger turbulence effect at the end close to the liquid outlet, so that the ability of the coolant in various places in the liquid-cooling channel to carry away heat is more uniform, reducing the difference in heat dissipation effect of various components installed on the upper surface of the liquid-cooled radiator, and making the temperature distribution of various components for which the radiator provides heat dissipation more uniform.

[0020] Reference Figure 1 and Figure 2 As shown, this embodiment discloses a turbulent heat-averaging liquid-cooled radiator, 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, the axis of the turbulator 3 is a straight line, and the pitch of the turbulator 3 near the liquid inlet end is greater than the pitch near the liquid outlet end.

[0021] The present embodiment discloses a turbulent heat-averaging liquid-cooled heat sink 1, in which a spiral coil-shaped turbulator 3 is arranged in a liquid-cooling channel 2, and the pitch of the turbulator 3 at the end close to the liquid inlet is larger than the pitch at the end close to the liquid outlet, thereby forming a weaker turbulence effect at the end close to the liquid inlet and a stronger turbulence effect at the liquid outlet, so that the ability of the coolant at various locations in the liquid-cooling channel 2 to carry away heat is more uniform, reducing the difference in heat dissipation effect of various components installed on the upper surface of the liquid-cooled heat sink 1, and making the temperature distribution of various components for which the heat sink 1 provides heat dissipation more uniform.

[0022] Specifically, the liquid cooling channel 2 is cylindrical in shape, five of them are arranged side by side, and the multiple liquid cooling channels 2 are parallel to each other.

[0023] In this embodiment, the outer diameter of the turbulator 3 is slightly smaller than the inner diameter of the liquid cooling channel 2. As a preferred embodiment of this embodiment, the turbulator 3 is divided into three sections connected in sequence, the first section is close to the water inlet, the third section is close to the water outlet, and the middle section is the second section. The three sections of the turbulator 3 all have a fixed pitch, and the pitch of the first section is greater than that of the second section, and the pitch of the second section is greater than that of the third section.

[0024] Specifically, the radiator 1 is a rectangular parallelepiped structure, and the axis of the liquid cooling channel 2 is perpendicular to two opposite surfaces of the radiator 1 and forms a liquid inlet and a liquid outlet.

[0025] As a preference of this embodiment, the heat sink 1 is made of one of aluminum and copper.

[0026] Working principle: The power devices on the radiator 1 generate heat at basically the same rate, and the temperature of the coolant is lowest at the water inlet. As the heat accumulation gets closer to the water outlet, the coolant temperature gets higher, which results in the power devices near the water inlet having a low temperature, while the power devices near the water outlet have a high temperature, which is not conducive to the temperature uniformity requirement of the devices. The coolant of the liquid-cooled radiator 1 of this invention enters the heat dissipation channel of the radiator 1 from the liquid inlet. At the front end of the heat dissipation channel, due to the large pitch of the turbulator 3, the turbulence effect is weak, and the heat dissipation effect is poor at this time. When the coolant enters the rear end of the heat dissipation channel, due to the small pitch of the turbulator 3, the turbulence effect is strong, and the heat dissipation effect is strong at this time, so that the heat taken away by the front and rear ends of the heat dissipation channel of the coolant is evenly distributed, and finally the coolant flows out of the heat dissipation channel from the liquid outlet, taking away the heat.

[0027] 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.

[0028] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. 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.
