Problems solved by technology

[0017] In order to solve the lack of integrally formed three-dimensional water-cooling devices in the prior art, multiple plane water-cooling plates are usually spliced ​​together in the prior art. This method has many disadvantages, such as limited shape, excessive volume, and presence of flow channel joints. Heat leak points lead to problems such as uneven heat distribution

Embodiment approach 1

[0073] combine Figure 3-7 Describe this embodiment, an ultra-thin three-dimensional water-cooling device of this embodiment, the device is processed into a three-dimensional shape by a water-cooled plate, the thickness of the water-cooled plate is 0.5mm-3.5mm, and the water-cooled plate is composed of two plates superimposed on each other and The fixed connection is realized by diffusion welding, wherein at least one plate side wall is etched with a water flow channel, the water flow channel is located between the two plates, and any one of the two plates is provided with a connection with the water flow channel The water inlet and outlet corresponding to the water end and the water outlet.

[0074] In this embodiment, a water flow channel is etched on the side wall of one plate, and the other plate is a flat plate, such as image 3 shown; it is also possible to etch the water flow channel on the side walls of the two plates, and then fasten the sides of the two plates with ...

Embodiment approach 2

[0100] combine Figure 8-14 Describe this embodiment, an ultra-thin three-dimensional water-cooling device of this embodiment, the device is bent and processed into a three-dimensional shape by a water-cooled plate, the thickness of the water-cooled plate is 0.5mm-3.5mm, and the water-cooled plate is composed of three plates. Superimposed and fixedly connected by diffusion welding, wherein the middle plate is provided with a hollowed-out water flow channel, and any one of the plates on both sides is provided with an inlet port corresponding to the water inlet end and the water outlet end of the water flow channel. Water inlet and outlet.

[0101] The hollow water flow channel in this embodiment can be formed by wire cutting, laser cutting or plasma cutting, among which wire cutting is better, because the wire cutting method has high dimensional accuracy, which can be as high as 0.02mm, and there is no waste on the cut surface , The deformation of the plate is small.

Abstract

The invention discloses an ultrathin three-dimensional water-cooling device and a machining method thereof, and belongs to the field of water-cooling plate machining. The ultrathin three-dimensional water-cooling device provided by the invention is machined into a three-dimensional shape from a water-cooling plate, the thickness of the water-cooling plate is 0.5mm-3.5mm, and the width of a part vertical to the plate surface of the water-cooling plate, of a water flow flowing channel, is 50%-70% of the thickness of the water-cooling plate. The water-cooling device can be machined into an integrated spatial three-dimensional structure with any size as needed; and moreover, the machined three-dimensional shape is unlimited, a leakage point at a turning point / bending part is avoided, and non-uniform local heat dissipation due to the heat leakage point is avoided. The water-cooling device is applicable to heat dissipation for a component.

Description

technical field [0001] The invention relates to an ultra-thin three-dimensional water cooling device and a processing method thereof, belonging to the field of water cooling plate processing. Background technique [0002] In the prior art, most of the heat dissipation in the plane is used, there are few three-dimensional heat dissipation structures, and the efficiency of the plane heat dissipation is low. In some cases, the plane heat dissipation cannot meet the heat dissipation requirements, and the space heat dissipation can greatly improve the heat dissipation efficiency and achieve the purpose of rapid heat dissipation. is a research focus in this field. [0003] There are generally three methods to solve the problem of heat dissipation at high temperature: 1. Water cooling method, 2. Air cooling method, 3. The method of using heat insulation materials, among which: [0004] 1. Water cooling method [0005] The conventional water cooling method is in the form of a flat...
