Description

Technical Field

[0001] The utility model belongs to the technical field of liquid cooling radiators, and in particular relates to a split water cooling radiator. Background Art

[0002] The radiator is a component used to reduce the operating temperature of the device. Currently, PC cooling mainly includes air cooling, water cooling and passive cooling.

[0003] As the power consumed by electronic components increases, the heat they emit during operation also increases. In addition, there are too many internal components in the computer case, which will generate a lot of heat during operation and is prone to uneven distribution. Poor heat dissipation will lead to a sharp decline in the reliability and life of components in the circuit, which puts higher requirements on heat dissipation. Accordingly, in order to improve the reliability and life of the entire circuit, active (such as air cooling, water cooling) / passive cooling methods are generally adopted to cool key heat-generating components to reduce heat accumulation, such as active heat dissipation of CPU and GPU devices on computer motherboards. However, with the surge in the overall stacking density of the circuit and the density of devices, the existing air-cooled heat dissipation is not effective enough for chips with higher power consumption, and the existing water-cooled heat dissipation has a low internal turbulence and cannot maximize the water cooling effect. Therefore, a single heat dissipation mode cannot meet the overall heat dissipation requirements of devices under small space and high heat flow conditions.

[0004] With regard to the above-mentioned related issues, there is currently no good comprehensive heat dissipation solution. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-4 The utility model provides the following technical solutions: a water-cooled radiator, including a water-cooling block, a pipe, namely a water inlet pipe 8 and a water outlet pipe 9, a cold row 11, and a pump body 10. The water-cooling block includes a base 1 in contact with the heat dissipation device, and there are multiple groups of rectangular water-cooling channels 2 inside the base 1. The four walls of the rectangular water-cooling channel 2 are arranged with two-by-two staggered oblique ribs 3. The inclination angle of the oblique ribs 3 is 30° to 60°, which is the best. The oblique ribs on adjacent walls are staggered, and the staggered distribution is based on the midline of two ribs of the adjacent rib group. In order to improve the applicability of the utility model, the parameters such as the rib spacing and rib height of the staggered ribs in the rectangular water-cooling channel 2 and the ribs 6 in the heat dissipation fin group 5 can be adjusted accordingly according to the actual heat dissipation scenario. Preferably, the rib length is between 0.5-0.75 of the width of the rectangular cooling channel, and the aspect ratio is between 4:1-10:1. The upper side of the water-cooling channel base 1 is provided with extended heat dissipation ribs 6, which are arranged at a certain angle along the cooling airflow direction of the fan 7, and the heat dissipation ribs 6 are provided with a heat dissipation fin group 5 for enhancing heat dissipation, and a fan assembly 7 is installed on one side of the heat dissipation fin group 5. Above the base 1, there is a mounting base 4 for fixing the radiator. The water-cooling block and the radiator 11 are connected by an inlet pipe 8 and an outlet pipe 9, and a pump body 10 is installed on the outlet pipe 9 for driving the water flow. In this embodiment, by means of a rectangular water-cooling channel with staggered oblique ribs arranged inside the water-cooling block and a heat dissipation fin group on the upper side, air cooling and water cooling are combined to improve the cooling efficiency, and the internal cooling fluid can also achieve secondary heat exchange, which simplifies the structure of the split water cooling to a certain extent and also improves the overall heat dissipation in the chassis.

[0026] In order to accelerate the heat exchange between the cooling fluid in the radiator 11 and the outside, in this embodiment, as a preferred technical solution of the utility model, staggered oblique ribs 3 similar to those in the rectangular water cooling channel 2 are arranged in the cooling pipe inside the radiator to enhance convective heat exchange.

[0027] In order to enhance the heat exchange effect, in this embodiment, commonly used thermal conductive silicone grease is used to fill the space between the heat dissipation component and the base 1 to reduce the contact thermal resistance.

[0028] To sum up, with the help of the above-mentioned technical scheme of the utility model, the water cooling block base 1 is fixed and contacts the CPU surface (the CPU is arranged under the water cooling block base 1), and is filled with silicone grease. After the pump body 10 is energized, the radiator 11 exchanges heat with the cooling water, and the cooled water flows into the rectangular water cooling channel 2 through the water inlet pipe 8, and takes away the heat generated by the CPU through convection heat exchange. The heat dissipation fin group 5 on the upper side of the base 1 can also take away the heat and reduce the temperature of the base 1. The rectangular water cooling channel 2 and the heat dissipation fin group 5 can increase the area of ​​convective heat exchange and increase the turbulence to accelerate heat exchange. After passing through the water outlet, the water flow is pushed back to the radiator 11 by the pump body 10 through the water outlet pipe 9 to complete the cycle through secondary heat exchange with the air.

[0029] Figure 5 70W / cm 2 Simulation comparison of the maximum temperature and average temperature of the chip surface under different structures under heat flow, example-1 is a smooth water cooling head without fins arranged in the water cooling channel, example-2 is a water cooling head with traditional parallel transverse ribs, and example-3 is a water cooling block of the utility model. It can be seen from the figure that the water cooling radiator of the utility model can significantly improve the heat dissipation efficiency and performance.

[0030] The utility model arranges multiple groups of water-cooling channels with staggered oblique ribs on the wall inside the base, which can not only increase the heat exchange area, but also enhance the fluid disturbance near the wall to further enhance the heat exchange; the ribs above the base and the heat dissipation fin group thereon can further reduce the base temperature by convective heat exchange with the air, and can also form a heat dissipation channel with a fan as the inlet and multiple outlets, which can be combined with other components to form an overall heat dissipation duct. For example, in a computer case, the graphics card is located at the inlet, and the upper and rear sides of the case correspond to the outlet, so that an inner case duct with a route of graphics card-CPU-memory bar-upper and rear sides of the case can be formed, thereby reducing the overall temperature inside the case.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for those skilled in the art to

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
