Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a VC heating copper block tooling. Background Art

[0002] A vapor chamber (VC) is a common mechanism for rapid heat conduction and dissipation. Its operating principle is that a working medium circulates in a closed, plate-like cavity, evaporating and condensing, achieving rapid heat conduction and diffusion, and rapidly achieving uniform temperature. As a new two-phase flow heat dissipation technology, the vapor chamber offers advantages such as high thermal conductivity, excellent temperature uniformity, and reversible heat flow. It overcomes the limitations of traditional heat pipes, such as small contact area, high thermal resistance, and uneven heat flux density. It has become an effective solution for dissipating high-heat-density electronic devices in the future electronics industry.

[0003] The heat dissipation industry has increasingly stringent requirements for temperature detection. Before R&D or product shipment, the vapor chamber must be temperature-tested to detect temperature changes at different locations and times during the heat dissipation process. Currently, thermocouple wires are typically used for vapor chamber detection. Thermocouple wires are a type of temperature sensing element that utilizes two metal conductors of different materials. However, manual operation and the presence of human error result in low efficiency and insufficient accuracy. Utility Model Content

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant content and are not intended to limit the present invention. It should also be noted that, for ease of description, only the portions relevant to the present invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Example: See Figure 1 ,

[0019] A VC heating copper block tooling includes a heating copper block body 1, multiple first thermocouple wires 21, and multiple heating rods 3. Multiple heating rods 3 are installed inside the heating copper block body 1, and the heating rods 3 do not contact each other. Multiple first grooves 41 are provided on the upper surface of the heating copper block body 1, and the first thermocouple wires 21 are fixed in the first grooves 41, and the first thermocouple wires 21 do not contact each other.

[0020] The working principle of the temperature averaging plate 6 is as follows: the temperature of the heat source is transferred to the temperature averaging plate 6, causing the working medium in the enclosed plate-shaped cavity within the temperature averaging plate 6 to undergo a phase change. The working medium circulates in a state of evaporation and condensation, rapidly conducting and diffusing heat, achieving the characteristic of rapid temperature uniformity. During the temperature detection process of the temperature averaging plate 6, the actual working process of the heat source and the temperature averaging plate is simulated. The heating copper block body 1 is located below the temperature averaging plate 6, and the heating rod 3 is used to heat the heating copper block body 1. The heated heating copper block body 1 acts as a heat source. The heat source contacts the temperature averaging plate 6, that is, the upper surface of the heating copper block body 1 contacts the lower surface of the temperature averaging plate 6. The heat from the heating copper block body 1 is transferred to the temperature averaging plate 6, and the heat is transferred away by absorbing heat through two-phase phase change inside the temperature averaging plate 6. The first thermocouple wire 21 is used to detect (collect) the temperature of the heating copper block body 1 at different positions and different heat dissipation times, thereby calculating the temperature changes and trends at different positions on the upper surface (heat source) of the heating copper block body 1, which is used to determine whether the heat dissipation power and heat dissipation and temperature uniformity performance of the temperature averaging plate 6 meet the requirements.

[0021] The first groove 41 is filled with a first solder paste 51, which is located outside the first thermocouple wire 21. The upper surface of the first solder paste 51 is flush with the upper surface of the heating copper block body 1. This flushness ensures that the upper surface of the heating copper block body 1 is in contact with the lower surface of the temperature plate 6. During temperature detection, the first solder paste 51 is located outside the first thermocouple wire 21, ensuring that the first thermocouple wire 21 and the heating copper block body 1 are insulated, preventing temperature changes caused by contact between the first thermocouple wire 21 and the heating copper block body 1, thereby ensuring accurate temperature detection on the heating copper block body 1.

[0022] Multiple heating rods 3 are evenly connected within the heating copper block body 1, and multiple first grooves 41 are evenly distributed on the upper surface of the heating copper block body 1. In this embodiment, the multiple heating rods 3 are placed parallel to each other and at equal spacing, which can uniformly heat the heating copper block body 1. The multiple first grooves 41 are placed parallel to each other and at equal spacing, which are used to detect the temperature at different positions on the heating copper block body 1.

[0023] The heating copper block body 1 includes a first body 11, a second body 12 and a third body 13 fixedly connected in sequence from bottom to top. The upper surface cross-section of the third body 13 is the smallest, and a plurality of first grooves 41 are provided on the upper surface of the third body 13. In this embodiment, the surface areas of the first body 11, the second body 12 and the third body 13 become smaller in sequence. A threaded hole is provided on the first body 11 for fixing the heating copper block tooling, and the second body 12 is used to install the heating rod 3. The upper surface cross-section of the third body 13 is the smallest, and a plurality of first grooves 41 are provided on the upper surface of the third body 13. Its upper surface is in contact with the temperature equalizing plate 6 for temperature detection.

[0024] The first groove 41 has one or more of square, circular or triangular cross-sectional structures.

[0025] The VC heating copper block fixture also includes a temperature averaging plate 6 and multiple second thermocouple wires 22. Multiple second grooves are provided on the lower surface of the temperature averaging plate 6. The second thermocouple wires 22 are fixedly connected to the second grooves, and the second thermocouple wires 22 do not touch each other. The structure of the second grooves (not shown) can refer to the first grooves 41. The multiple second thermocouple wires 22 are used to detect (collect) the temperature at different positions and different heat dissipation times on the lower surface of the temperature averaging plate 6, thereby calculating the temperature changes and trends at different positions of the temperature averaging plate 6. Combined with the temperature changes and trends at different positions on the upper surface (heat source) of the heating copper block body 1, it is determined whether the heat dissipation power and heat dissipation temperature equalization performance of the temperature averaging plate 6 meet the requirements, resulting in higher temperature detection precision and accuracy.

[0026] The second groove is filled with second solder paste 52, which is located outside the second thermocouple wire 22. The lower surface of the second solder paste 52 is flush with the lower surface of the vapor chamber 6. During temperature measurement, the second solder paste 52 is located outside the second thermocouple wire 22, ensuring insulation between the second thermocouple wire 22 and the vapor chamber 6. This prevents temperature fluctuations caused by contact between the two wires and ensures accurate temperature measurement on the vapor chamber 6.

[0027] The number of second thermocouple wires 22 is the same as that of first thermocouple wires 21, and the second thermocouple wires 22 correspond vertically to the first thermocouple wires 21. The same number of second thermocouple wires 22 and their corresponding vertical positions facilitate comparison of temperature changes on the heat spreader 6 and the heated copper block body 1, improving the accuracy of determining the heat dissipation power and heat dissipation and temperature equalization performance of the heat spreader 6.

[0028] In summary, the VC heating copper block tooling provided by the present invention heats the heating copper block body through multiple heating rods, so that the heating copper block body is equivalent to a heat source; multiple first thermocouple wires are used to measure (collect) the temperature of the heating copper block body at different positions and at different heat dissipation times, thereby calculating the temperature changes and trends at different positions on the upper surface (heat source) of the heating copper block body, which are used to judge whether the heat dissipation power and heat dissipation temperature equalization performance of the temperature equalization plate meet the requirements; multiple second thermocouple wires are used to detect (collect) the temperature of the lower surface of the temperature equalization plate at different positions and at different heat dissipation times, thereby calculating the temperature changes and trends at different positions of the temperature equalization plate, and combining the temperature changes and trends at different positions on the upper surface (heat source) of the heating copper block body to judge whether the heat dissipation power and heat dissipation temperature equalization performance of the temperature equalization plate meet the requirements, and the temperature detection precision and accuracy are higher.

Other variations or modifications may be made based on the above-described utility model, and such variations or modifications are still within the scope of the present invention.
