Abstract
Description
Technical Field
[0001] This application relates to the field of airborne electronic equipment enclosures, and more particularly to a liquid-cooled heat dissipation enclosure. Background Technology
[0002] With the increasing integration of electronic devices, components are becoming smaller and smaller, resulting in highly concentrated heat dissipation. This places higher demands on the reliability of electronic devices. The main cause of premature failure in electronic devices is overstress, namely electrical, thermal, and mechanical stress, with a close relationship between electrical and thermal stress. Electronic devices require suitable operating temperatures; prolonged overheating can lead to malfunctions or failures. Temperature changes significantly affect the failure rate of electronic components; data shows that 70% of electronic device failures are related to excessively high thermal environments. The percentage increase in failure rate for electronic devices at an initial temperature of 50°C is shown for different temperature rises. The failure rate of electronic devices increases exponentially with increasing temperature. This is because thermal coupling occurs between components through convection, conduction, and radiation. Therefore, temperature has a crucial impact on the performance of electronic devices. Utility Model Content

[0030] This application provides a liquid-cooled heat dissipation chassis.
[0031] like Figures 1 to 4 As shown, a liquid-cooled heat dissipation chassis includes a front mounting plate 1, a rear mounting plate 2, an upper cooling plate 3, a lower cooling plate 4, a left cooling plate 5, and a right cooling plate 6. The front mounting plate 1, rear mounting plate 2, upper cooling plate 3, lower cooling plate 4, left cooling plate 5, and right cooling plate 6 form a cubic chassis. In this embodiment, the upper cooling plate 3, lower cooling plate 4, left cooling plate 5, and right cooling plate 6 are joined together by electron beam welding, resulting in higher welding strength and more reliable sealing. The front mounting plate 1 is connected to the end faces of the upper cooling plate 3, lower cooling plate 4, left cooling plate 5, and right cooling plate 6 by bolts, and the rear mounting plate 2 is also connected to the end faces of the upper cooling plate 3, lower cooling plate 4, left cooling plate 5, and right cooling plate 6 by bolts.
[0032] The upper cold plate 3 and the lower cold plate 4 are both provided with fluid channels 7; the right cold plate 6 is provided with an inlet channel 8 and an outlet channel 9 arranged at intervals, and the left cold plate 5 is provided with a conveying channel 10.
[0033] The inlet of the liquid inlet channel 8 is connected to external coolant. The outlet of the liquid inlet channel 8 is connected to the inlet end of the fluid channel 7 of the upper cold plate 3. The outlet of the fluid channel 7 of the upper cold plate 3 is connected to the inlet of the conveying channel 10. The outlet of the conveying channel 10 is connected to the inlet of the fluid channel 7 of the lower cold plate 4. The outlet of the fluid channel 7 of the lower cold plate 4 is connected to the inlet of the outlet channel 9. The outlet of the outlet channel 9 is connected to an external pipe. The coolant passes sequentially through the liquid inlet channel 8, the fluid channel 7 of the upper cold plate 3, the conveying channel 10, the fluid channel 7 of the lower cold plate 4, and the outlet channel 9.
[0034] Furthermore, in this application, the central axes of the inlet and outlet of the same fluid channel 7 are perpendicular to the right cold plate 6. That is, the inlet and outlet of the same fluid channel 7 are aligned, and the flow direction of the fluid in the inlet and outlet of the same fluid channel 7 is perpendicular to the right cold plate 6. Moreover, the central axes of the inlet and outlet of the fluid channel 7 are vertically coincident.
[0035] The left cold plate 5 and right cold plate 6 are only wider in the areas without flow channels, while the width between them is smaller in the areas with flow channels. Furthermore, the inlet flow channel 8, outlet flow channel 9, and conveying flow channel 10 are all located on a single side cold plate, resulting in a smaller area of greater width on both side cold plates. This application places the inlet flow channel 8 and outlet flow channel 9 flowing to the upper cold plate 3 on one side plate, and the conveying flow channel 10 flowing to the lower cold plate 4 on another side plate. Moreover, the flow channels on the left cold plate 5 and the right cold plate 6 are almost aligned, reducing the narrower areas and increasing the wider areas, thereby improving the usable installation space inside the chassis.
[0036] The inlet of the inlet channel 8 and the outlet of the outlet channel are located in the middle of the right cold plate 6, and the inlet of the inlet channel 8 and the outlet of the outlet channel are located on the side of the right cold plate 6 near the front mounting plate 1. The inlet channel 8 extends from the end face of the right cold plate 6 near the front mounting plate 1 towards the rear mounting plate 2 to the middle of the right cold plate 6, and then turns and extends to the upper cold plate 3. The outlet channel 9 extends from the end face of the right cold plate 6 near the front mounting plate 1 towards the rear mounting plate 2 to the middle of the right cold plate 6, and then turns and extends to the lower cold plate 4. In this embodiment, the direction from the front mounting plate 1 to the rear mounting plate 2 is the first direction, and the extension length of the inlet and outlet channels along the first direction is less than half the length of the right cold plate 6 along the first direction. The inlet channel 8 and the outlet channel 9 are L-shaped, and the infusion channel on the left cold plate 5 is strip-shaped, with its length direction perpendicular to the upper cold plate 3.
[0037] The right cold plate 6 has a mounting block 11 on its end face near the front mounting plate 1. The mounting block 11 protrudes from the right cold plate 6 toward the left cold plate 5. The front mounting plate 1 has a groove to accommodate the mounting block 11. The mounting block 11 has a first channel communicating with the liquid inlet channel 8 and a second channel communicating with the liquid outlet channel 9.
[0038] The mounting block 11 has a first connector 12 and a second connector 13 on its side facing away from the mounting plate. The first connector 12 is connected to the first channel, and the second connector 13 is connected to the second channel.
[0039] The fluid channels 7 within the upper cooling plate 3 and the lower cooling plate 4 are arranged in a serpentine pattern.
[0040] Weight reduction grooves 14 are provided on the outer and inner surfaces of the upper cold plate 3 and the lower cold plate 4. Weight reduction design is implemented for the structure outside the flow channel.
[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
