Description

Technical Field

[0001] This utility model relates to the field of cold plate technology, and more specifically, to a composite material cold plate. Background Technology

[0002] Traditional cold plates typically employ a planar structure on the side facing the coolant chamber, with the coolant chamber in direct contact with the cold end surface, achieving heat exchange through conduction and convection. However, this design suffers from drawbacks: the planar structure results in a small contact area between the coolant and the cold end, leading to high thermal resistance and difficulty in improving heat dissipation efficiency. Therefore, we propose an improvement by developing a composite material cold plate. Utility Model Content

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-6A composite material cold plate includes a shell 1, a coolant cavity 101 is provided on one side of the shell 1, and a cold end substrate 2 is provided at the opening of the coolant cavity 101. A connecting plate 201 is provided on the side of the cold end substrate 2 facing the inside of the coolant cavity 101, and a plurality of spade teeth 202 are provided on the side of the connecting plate 201 away from the cold end substrate 2. The cold end substrate 2, the connecting plate 201 and the spade teeth 202 are integrally formed, which increases the contact area with the coolant and thus improves the heat dissipation efficiency. The integrally molded cold-end substrate 2, connecting plate 201, and spade teeth 202, on the one hand, avoid gaps at the joints of various components, reduce thermal resistance, and allow the heat absorbed by the cold-end substrate 2 to be transferred more smoothly to the connecting plate 201 and spade teeth 202; on the other hand, the spade teeth significantly increase the contact area with the coolant, allowing the heat to be carried away more fully by the coolant. This dual effect significantly improves heat dissipation efficiency and solves the heat dissipation bottleneck caused by poor heat conduction and limited contact area in traditional spliced ​​structures. Furthermore, the cold end substrate 2, the connecting plate 201, and the shovel teeth 202 are all made of copper diamond composite material. Specifically, the cold end substrate 2, the connecting plate 201, and the shovel teeth 202 are stamped and formed from copper diamond composite material to form an integral structure. The integral molding setting makes the heat conduction effect better.

[0020] Furthermore, the cold end substrate 2 is positioned so that the middle part of the side away from the connecting plate 201 is protruding. This arrangement facilitates contact between the cold end substrate 2 and the component to be cooled. The cold end substrate 2 is connected to the housing 1 by welding.

[0021] Furthermore, the coolant cavity 101 has an installation port 102 at its opening. The inner wall of the installation port 102 is inserted into the cold end substrate 2. The installation port 102 is provided to provide positioning and the necessary space for the installation of the cold end substrate 2. At the same time, the initial fixation formed by the insertion can provide a stable assembly state for subsequent welding processes and reduce the sealing problems caused by component displacement during welding.

[0022] Furthermore, the housing 1 has two connecting ports 103, both of which are connected to the coolant cavity 101; the shovel teeth 202 are located between the two connecting ports 103, so that there is space for coolant mixing between both ends of the shovel teeth 202.

[0023] Furthermore, the housing 1 is fixedly connected to a connecting pipe 105 that communicates with the connecting port 103. A connecting nozzle 106 is fixedly connected to one side of the connecting pipe 105. The connecting pipe 105 is welded together with the housing 1 and the connecting nozzle 106. The connecting nozzle 106 is used to connect with a pipeline for conveying coolant.

[0024] Furthermore, a positioning groove 104 is provided on the housing 1. The position of the positioning groove 104 corresponds to the position of the connecting port 103, and the positioning groove 104 is inserted into the bottom end of the connecting pipe 105. The positioning groove 104 can play a positioning role for the connecting pipe 105 during welding.

[0025] Furthermore, the housing 1 has a plurality of mounting holes 107, which are used to mount the present application onto the corresponding component by means of bolts.

[0026] The coolant enters the coolant cavity 101 through one of the connecting nozzles 106, connecting pipes 105 and connecting ports 103, and then cools the cold end substrate 2 through the cold end substrate 2, connecting plate 201 and spade teeth 202, and then is discharged through one of the connecting ports 103, connecting pipes 105 and connecting nozzles 106.
