Description

Technical Field

[0001] This utility model relates to the field of cold plate technology for electronic devices, and in particular to a multi-scale microchannel sealing structure. Background Technology

[0002] Multi-scale liquid cooling systems in electronic devices, where the main liquid cooling channel's cold plate and the microchannel cold plate are connected, typically employ eutectic welding, a brazing process performed at relatively low temperatures. During eutectic welding, a vacuum is evacuated and a protective gas is introduced into the eutectic furnace. However, the process curves for different weldment characteristics are difficult to determine, making it challenging to control welding and holding times. Furthermore, precise control of the vacuum level within the eutectic furnace can easily lead to weld voids after welding, affecting the density and weld success rate of the weldment. This results in a low yield and poor sealing of the produced weldments. Patent CN217470618U proposes a multi-scale liquid cooling channel sealing structure. This solution achieves sealing through screw assemblies and sealing gaskets. This sealing method is suitable for sealing connections between multi-scale liquid cooling channels, without affecting the fluid flow path, and solves the sealing problem between the main liquid cooling channel's cold plate and the microchannel cold plate at a low cost and without risk.

[0003] However, the sealing gasket used in this sealing structure to achieve the sealing between the main cold plate and the micro cold plate is a single-piece structure, so its sealing effect needs to be improved. In view of the above reasons, this application proposes a multi-scale microchannel sealing structure with high sealing connection effect. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a multi-scale microchannel sealing structure with high sealing connection effect.

[0005] The technical solution of this utility model is: a multi-scale microchannel sealing structure, including a main cold plate body and a microcold plate body disposed on one side of the main cold plate body. A main channel is opened in the main cold plate body, and the microcold plate body is installed at the position corresponding to the main channel. A channel hole penetrating the main cold plate body is opened on one side of the main channel.

[0006] The micro-cooled plate body has micro-channel holes, and the micro-channel holes are opened at the corresponding channel hole positions. A clamping ring is fixedly connected to the side of the micro-cooled plate body, and the inner ring of the clamping ring is set as a through hole at the corresponding channel hole position.

[0007] A sealing gasket is provided on one side of the outer ring of the flow channel hole, which is installed on the inner concave surface of the clamping ring.

[0008] Optionally, the sealing gasket has a built-in cavity and is made of soft rubber, with one side of the sealing gasket being engaged with the concave surface of the retaining ring.

[0009] Optionally, the main cold plate body has multiple mounting slots on its side, and each mounting slot has a slot on its side located on the main cold plate body, and the other side of the sealing gasket is fitted into the slot.

[0010] Optionally, each of the micro-cold plate bodies has two sets of microchannel holes.

[0011] The micro-cold plate body also has corresponding threaded holes;

[0012] The mounting slot has a threaded groove at the position corresponding to the threaded hole.

[0013] Optionally, bolts are rotatably installed in both the threaded hole and the threaded groove, corresponding to the threaded rotation.

[0014] Optionally, the main cold plate body has a flow channel opening on its side, and the flow channel opening is connected to the main flow channel.

[0015] Optionally, mounting bosses are provided at the four corners of the main cold plate body.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This utility model achieves a tight seal between the micro-cold plate body and the main cold plate body by setting bolts, which is used to meet the sealing of multi-scale microchannels. Moreover, the sealing method can be adjusted according to the actual structure and usage of the cold plate, so the sealing structure is highly operable.

[0018] This utility model, through the special structure of the sealing gasket, achieves the separation of the hollow cavity while bringing the micro-cooling plate body close to the inner wall of the mounting groove, thereby sealing the contact surfaces between the clamping ring and the mounting groove, thus improving the sealing effect. As the bolts are continuously rotated to install the micro-cooling plate body, the sealing effect will be enhanced.

[0019] In summary, the multi-scale microchannel connection designed in this invention has strong sealing performance and high adjustability. The special structure of the sealing gasket continuously enhances its sealing performance during assembly, achieving a highly efficient sealing effect. Attached Figure Description
