Description

Technical Field

[0001] This utility model relates to the technical field of a temperature equalization plate, and more particularly to a temperature equalization plate with a support column reinforcement structure. Background Technology

[0002] Existing heat spreaders mainly consist of a shell, a plurality of support columns, and a working fluid. The support columns are spaced apart and distributed inside the shell, thereby achieving rapid heat conduction and heat dissipation through vapor or liquid phase changes of the working fluid.

[0003] However, while existing heat spreaders possess excellent heat conduction and dissipation capabilities, the following problems remain to be addressed in practical applications: Because the support columns are first welded to the shell, followed by powder sintering and / or capping, various defects, such as breakage between the support columns and the shell, frequently occur during the powder sintering or capping process, with longer support columns exhibiting more severe breakage. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] Please see Figures 1 to 4 As shown, this utility model provides a temperature equalization plate with a support column reinforcement structure, which mainly includes a shell 10, a plurality of (two or more) support columns 20, a reinforcement structure 30 and a working fluid 40.

[0023] The shell 10 mainly includes a first shell plate 11 and a second shell plate 12. The first shell plate 11 and the second shell plate 12 are made of materials with good thermal conductivity, such as copper, aluminum, magnesium, or their alloys. The first shell plate 11 mainly includes a bottom plate 111 and a surrounding plate 112 that bends upward from the periphery of the bottom plate 111. A flange 113 extends outward from the end of the surrounding plate 112 away from the bottom plate 111. The first shell plate 11 also includes a recessed area 114, which is formed in the middle region of the bottom plate 111. That is, the longitudinal distance from the inner bottom surface of the recessed area 114 to the flange 113 is greater than the longitudinal distance from the bottom plate 111 to the flange 113. In this embodiment, the second shell plate 12 is a flat plate, but this form is not a limitation. The periphery of the second shell plate 12 is in close contact with and sealed to the flange 113 of the first shell plate 11, so as to form a cavity A between the first shell plate 11 and the second shell plate 12.

[0024] Each support column 20 is evenly distributed in the cavity A and is sandwiched between the first shell plate 11 and the second shell plate 12. In this embodiment, the support column 20 is a solid cylinder, which can be made of a material with good thermal conductivity such as copper, aluminum, magnesium or their alloys.

[0025] In one embodiment, each support column 20 can be welded using a spot welding machine (or, more accurately, a butt welder). During operation, pressure is first applied to bring each support column 20 into close contact with the inner surfaces of the aforementioned base plate 111 and the recessed area 114. Then, current is applied, and under the influence of resistance heat and a large amount of plastic deformation energy, the two separated metal atoms approach the lattice distance to form metallic bonds, generating a sufficient amount of common grains on the bonding surface to achieve a welded bond. Similarly, one end of each support column 20 can also be fixed to the inner surfaces of the aforementioned base plate 111 and the recessed area 114 using a welding material such as copper paste.

[0026] In one embodiment, each support column 20 mainly includes a plurality of first support columns 21 and a plurality of second support columns 22. The height of each second support column 22 is greater than the height of each first support column 21. Each second support column 22 is arranged in the aforementioned sunken area 114, while each first support column 21 is arranged in the aforementioned base plate 111.

[0027] The reinforced structure 30 is fitted with each of the support columns 20 corresponding to a portion of the structure, and mainly includes a plate 31 and a plurality of hollow sleeves 32 extending from the plate 31. Each hollow sleeve 32 is fitted around the outside of each second support column 22.

[0028] In one embodiment, each hollow sleeve 32 includes a plurality of arc-shaped plates 321, and one end of each arc-shaped plate 321 facing away from the plate body 31 is configured as a triangular block 322, and an airflow channel 323 is formed between any two adjacent triangular blocks 322.

[0029] The working fluid 40 can be pure water, which is injected into the aforementioned cavity A and subjected to a degassing and sealing process, thereby forming a vacuum chamber in cavity A.

[0030] In one embodiment, the temperature equalization plate with the support column reinforcement structure of the present invention further includes a powder sintering structure 50, which is coated on the surface of the aforementioned base plate 111, surrounding plate 112, each first support column 21, each second support column 22 and the second shell plate 12.

[0031] In one embodiment, the powder sintering structure 50 is located between each hollow sleeve 32 and each second support column 22.

[0032] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model, or reasonable combinations of features and solutions from various embodiments, are all within the protection scope of the present utility model.
