[0001] The utility model relates to the technical field of radiators, in particular to a VC heating copper block temperature sensing probe tool. 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, temperature detection of vapor chambers is typically performed manually using thermocouple wires, which results in large manual errors and low efficiency. Utility Model Content

[0017] Example: See Figure 1 ,

[0018] A VC heating copper block temperature sensing probe point tooling includes a heating copper block body 1, multiple first thermocouple wires 21, multiple heating rods 3, and multiple temperature sensing probe assemblies. Multiple heating rods 3 are installed inside the heating copper block body 1, and the heating rods 3 do not contact each other. Multiple grooves 14 are provided on the upper surface of the heating copper block body 1, and the first thermocouple wires 21 are fixed in the grooves 14. The first thermocouple wires 21 do not contact each other. Multiple through holes 15 are provided on the heating copper block body 1, and temperature sensing probe assemblies are installed in the through holes 15.

[0019] The working principle of the temperature equalizing plate 6 is as follows: the temperature of the heat source is transferred to the temperature equalizing plate 6, so that the working medium in the closed plate-shaped cavity in the temperature equalizing plate 6 changes phase, and the working medium circulates in the evaporation and condensation state, quickly conducts and diffuses the heat, and achieves the characteristic of rapid temperature uniformity. In the temperature detection process of the temperature equalizing plate 6, the actual working process of the heat source and the temperature equalizing plate 6 is simulated. The heating copper block body 1 is located below the temperature equalizing plate 6, and the heating rod 3 is used to heat the heating copper block body 1. The heated heating copper block body 1 is equivalent to the heat source. The heat source is in contact with the temperature equalizing plate 6, that is, the upper surface of the heating copper block body 1 is in contact with the lower surface of the temperature equalizing plate 6, and the heat of the heating copper block body 1 is transferred to the temperature equalizing plate Plate 6, the interior of the temperature equalizing plate 6 uses two-phase phase change to absorb heat to transfer heat, and the first thermocouple wire 21 is used to detect (collect) the temperature of the heated 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 heated copper block body 1; the temperature sensing probe assembly is used to detect the temperature of the lower surface of the temperature equalizing plate 6 at different positions and different heat dissipation times, thereby calculating the temperature changes and trends at different positions of the temperature equalizing plate 6, combined with the temperature changes and trends at different positions on the upper surface (heat source) of the heated copper block body 1, to judge whether the heat dissipation power and heat dissipation temperature equalization performance of the temperature equalizing plate 6 meet the requirements, and the temperature detection precision and accuracy are higher.

[0020] The temperature sensing probe assembly includes two temperature sensing probe devices and an insulating wire sleeve 53; the temperature sensing probe device includes a temperature sensing probe 51, a spring 52 and a second thermocouple wire 22. The temperature sensing probe 51 is connected to the second thermocouple wire 22 through the spring 52. The insulating wire sleeve 53 is covered on the outside of the two temperature sensing probe devices. In the natural state, the temperature sensing probe 51 is higher than the upper surface of the heating copper block body 1. In the working state, under the action of the spring 52, the temperature sensing probe 51 is flush with the upper surface of the heating copper block body 1. The insulating wire sleeve 53 keeps the two temperature sensing probe devices insulated from the heating copper block body 1, preventing the temperature of the heating copper block body 1 from affecting the temperature data collected by the temperature sensing probe 51. In the working state, that is, when detecting the temperature of the temperature averaging plate 6, the temperature averaging plate 6 is located above the heating copper block body 1. Under the action of gravity, the temperature sensing probe 51 is pressed into the heating copper block body 1 as the spring 52 expands and contracts, and the upper end of the temperature sensing probe 51 contacts the lower surface of the temperature averaging plate 6, which is used to detect and collect the instantaneous temperature of the temperature averaging plate 6. During the detection process, the temperature sensing probe 51 does not cause any damage to the temperature averaging plate 6. This tooling structure is suitable for large-scale full inspection and testing of VC, heat pipes, and modules. Without damaging the temperature averaging plate 6, it can be used as a mass production jig for repeated testing to output key temperature data with higher accuracy and precision.

[0021] The heating copper block temperature sensing point tooling also includes a cover plate 7, which is a glass fiber locking plate. The cover plate 7 is located at the lower end of the through hole 15, which can ensure that the temperature sensing probe assembly is insulated from the outside world and ensure the accuracy of the temperature measurement by the temperature sensing probe 51.

[0022] The groove 14 is filled with solder paste 4, which is located outside the first thermocouple wire 21. The upper surface of the solder paste 4 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 the temperature detection process, the solder paste 4 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 two wires and ensuring the accuracy of temperature detection on the heating copper block body 1.

[0023] Multiple heating rods 3 are evenly connected within the heating copper block body 1, and multiple grooves 14 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 the upper surface of the heating copper block body 1. 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 grooves 14 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.

[0024] 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 grooves 14 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 grooves 14 are provided on the upper surface of the third body 13. Its upper surface contacts the temperature equalizing plate 6 for temperature detection. The first body 11, the second body 12 and the third body 13 are all provided with a through hole 15 for installing a temperature sensing probe assembly, which facilitates temperature detection at different positions on the temperature equalizing plate 6.

[0025] The groove 14 has one or more of square, circular or triangular cross-sectional structures.

[0026] In summary, the VC heating copper block temperature sensing probe point 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 of the upper surface (heat source) of the heating copper block body; the temperature sensing probe assembly detects (collects) the temperature of the lower surface of the temperature equalizing plate at different positions and at different heat dissipation times, thereby calculating the temperature changes and trends at different positions of the temperature equalizing plate, and combined with the temperature changes and trends at different positions of the upper surface (heat source) of the heating copper block body, it is judged whether the heat dissipation power and heat dissipation temperature equalization performance of the temperature equalizing plate meet the requirements, and the temperature detection accuracy is higher; more importantly, the temperature sensing probe assembly does not cause any damage to the temperature equalizing plate during the tooling detection process, and can be widely used in large-scale full inspection and testing of VC, heat pipes, and modules.
